The present application under Section 35 §119 of the Code of laws of the United States, claims the priority of an application entitled "Soft Handover Method for Multimedia Broadcast/Multicast Service in a CDMA Mobile Communication System" (How soft transfer service for a multimedia broadcast/multicast service in a mobile communication system mdcr), registered in the Patent office Korea on April 27, 2002 under the number 2002-23283, the contents of which are incorporated by reference into the present description.

The technical field

The present invention relates to a soft transfer service in mobile communication system multiple access code division multiplexing (mdcr) and, in particular, to a soft transfer service in a multimedia broadcast/multicast service.

Prior art

Currently, due to the development of the communications industry, services provided by mobile multiple access code division multiple access (referred to hereinafter as mdcr), expand at the expense of the multicast connection-oriented media, which transmit not only data for transmission of the speech signal, but also the data of large capacity, such as packet data and channel data. To maintain funds multicast connection-oriented media, was to offer the broadcast/multicast service, in which one data source maintains a number of terminals of subscribers (referred to hereinafter as "TA"). Broadcast/multicast service can be divided into cell broadcast service (referred to hereinafter as "IED"), i.e. based on the message, and a multimedia broadcast/multicast service (referred to hereinafter as "MUMU"), which supports multimedia data such as image and speech in real time, a still image, and text.

SVU is a service for the broadcast transmission of many messages on THE located in a particular zone. Specific service area, which provides an IED may be the entire area of the cell, where the functioning of the SAF. IMDS is a service for simultaneous voice data and image data and requires considerable resources transfer. Services MVM provided by the broadcast channel, as many services may be provided simultaneously in one cell.

In General, in an asynchronous mobile communication system is essentially not possible synchronization times between nodes B, because the nodes have their own independent timers, and the reference time of the nodes may vary from node to node. The unit of measurement timer called the Xia frame number of the node In (LCI). Each node may include multiple cells, and each cell has a timer that increases its value at regular intervals from LCI. Unit timer assigned to each cell, called a number system frame (NSC). One of the NSC has a duration of 10 MS, and the NSC has a value from 0 to 4095. One of the NSC consists of 38400 chips and one chip has a duration of 10 MS/38400.

Therefore, when the radio network controller (referred to hereinafter as "cattle") transmits data MUMU on the nodes, if there is no separate synchronization process between nodes (or cells), the corresponding nodes (or cells) will transmit data MUMU at different points in time. This means that when ONE moves into a new cell (or node), then he will not be able to take advantage of the existing service.

It is obvious that moves from the area of one cell area to another cell, and is not in the area of one cell. At this point, the standard voice continues due to the soft transfer service. However, soft handover maintenance services MWMO has not been previously defined. Therefore, if the terminal of the subscriber who receives the service provided by MUMU from a particular node In the zone of the specified cell, moves into the area of another cell, the terminal of the subscriber will not be able to continue to take data MUMU and must again perform the operation mandatory UN paid the implementation of MUMU to receive services MUMU from the new cell (or from the new node).

The invention

Detailed description the preferred option of carrying out the invention

Below are described several preferred embodiments of the present invention with reference to the accompanying drawings. In the drawings, identical or similar elements are denoted by the same positions, even if they are depicted in different drawings. In the following description, for brevity, omitted a detailed description of known functions and configurations incorporated in this application.

In the following description, the present invention presents one typical scenarios for achieving the technical objectives outlined above, and other possible embodiments of the present invention will be briefly mentioned without detailed description.

Below is a description of standard procedures for the transmission and reception Yes what were MUMU in an asynchronous mobile communication system, support service MUMU. Of course, the scheme proposed by the present invention can be applied also in an asynchronous mobile communication system having cattle and many nodes Century

Figure 1 shows that in the absence of a separate process synchronization between nodes, THAT receives data MUMU from nodes at different points in time due to the lack of synchronization between nodes Century I.e. in figure 1 illustrates the procedure of data transmission MUMU from cattle on THAT in an asynchronous mobile communication system, consisting of cattle and two nodes Century figure 1 assumes that the node has one cell.

As shown in figure 1, cattle 101 transmits data MUMU taken from the network, the first node 107 and the second node 103. With this purpose, we can assume that cattle 101 copies the data of MUMU two IMDS data block and then separately and simultaneously transmits the copied data blocks IMDS on the first and second node 102 and 103. The frame number of the connection (AUC) is transmitted together with the data of MUMU. However, while the data blocks of MUMU were transferred from cattle 101 at the same time, if we consider the transmission delay at nodes 102 and 103, the nodes 102 and 103 will accept data MUMU at different points in time. The nodes 102 and 103 must determine the number of system frame (NSC), where they will transfer data IMDS with AUC. AUC has a value from 0 to 255, and the NSC has a value from 0 to 4095. Therefore, the point of time of the data transmission MUMU with AUC, having a remainder value obtained by dividing the specific NSC 256, i.e. the resulting value obtained in the result of the operation modulo 256 on the NSC (NSC modulo 256), is defined as a specific NSC. For example, time with NSC=3076 is defined as the time data of MUMU with AUC=4.

Figure 1 position 110 represents the NSC, which is the time axis cell No. 1, and the NSC(N) and the NSC(N+1) represent the change in the NSC due to the passage of time. In accordance with the position data 110 to the BS(2) is transmitted to the NSC(N) hundredth No. 1, and the data from the BS(3) is transmitted to the NSC(N+1) - hundredth No. 1. Summarizing, the data from the BS(k) is transmitted to the NSC(N+k-2) - hundredth No. 1.

Figure 1 position 115 is the NSC, which is the temporal axis of the cell # 2, and NSC(M) and the NSC(M+1) represent the change in the NSC due to the passage of time. In accordance with the position data 115 with AUC(1) is transmitted to the NSC(M) hundredth No. 2, and data from the BS(2) is transmitted to the NSC(M+1) - hundredth No. 2. Summarizing, the data from the BS(k) is transmitted to the NSC(M+k-1) - hundredth No. 2.

Figure 1 presents an example in which the cell No. 1 and cell No. 2 is synchronized on the staff, but differ from each other by the NSC. I.e. figure 1 shows the case when the NSC in cell No. 1 is equal to N, the NSC cell No. 2 is equal to M. in General, However, different cells are combined with each other in the NSC, and at the time of the beginning of the frame. For the sake of convenience of explanation involves the I in the present invention, that different cells are combined with each other at the time of the beginning of the frame.

As cell No. 1 and cell No. 2 accept these IMDS with the same BS, different moments in time, moments in time transfer differ from each other. For example, honeycomb No. 1 transmits data MUMU with AUC(2) NSC(N), whereas the honeycomb No. 2 transmits data MUMU with AUC(2) NSC(M+1).

Figure 1 position 111 is a signal that THE No. 4, located in the area of transfer service takes from cell No. 1, and the position 112 is a signal that THE No. 4 takes from cell No. 2. THE number 4 can make a more accurate data MUMU by combining the signal received from cell No. 1, with the signal received from cell No. 2. At this point, the Union should be performed on the data of MUMU with the same AUC. For example, THE No. 4 combines the BS(2) data MUMU transmitted from the cell # 1 in the NSC(N), BS(2) data MUMU transmitted from the cell # 2 in the NSC(M+1).

However, the transmission delay between hundredth No. 1 and THE No. 4 may differ from the transmission delay between hundredth No. 2 and THE No. 4. Figure 1 is a transmission delay of the signal received from the cell # 2, and a relatively longer length than the transmission delay of the signal received from cell No. 1. Therefore, to combine THE No. 4 must be continuously store data IMDS taken from cell No. 1 in its buffer until you have taken the data of MUMU with still the same BS from cell No. 2. However, if the difference between the time when the accepted data MUMU from cell No. 1, and the time when the accepted data MUMU from cell No. 2, exceeds a predetermined value (for example, 256 chips), it becomes impossible to continuously storing the first received data MUMU in the buffer.

In order to solve the problem, MUMU with the same BS from many hundred should be THE one located in the area of transfer service within a predetermined period of time.

Therefore, in the present invention, a method of synchronizing time of transmission of many hundreds, so that the same data MUMU transmitted from multiple cells may be accepted THAT within a predetermined period of time, and the way THE merge accept the same data, MUMU. The present invention provides that if the service IMDS is supported in an asynchronous mobile communication system must synchronize the time of data transfer between nodes In order to provide a soft transmission service at THE. However, as indicated above, in an asynchronous mobile communication system to synchronize time between nodes is not provided. I.e. in an asynchronous mobile communication system, the synchronization is performed only between the cattle and the host and between the host and THE. Therefore, in an asynchronous mobile communication system supporting the service MUMU, the difference between the time data of MWMO should be minimized by achieving synchronization between the frames, to obtain a soft transfer. This allows THE one which receives the same data from different nodes, to perform soft combining accept the same data. Therefore, although THE moves from one cell to another cell THAT can continuously take data MUMU without loss of data.

To synchronize the time of the transfer of all of the nodes In the existing one cattle, as stated above, THAT informs cattle on the relative temporal information for the moments of time when it receives the data transmission from each cell, and cattle synchronizes the time of transmission of the respective nodes based on the relative time information.

In an asynchronous mobile communication system supporting the service MUMU, in accordance with the embodiment of the present invention, in order to support the service MUMU for THAT, you want a soft transmission service required the following procedures: 1) the synchronization of the nodes; 2) measurement procedure for smooth transfer of THE service in the service MWMO and the synchronization time data transmission node Century

N. the same is the detailed description of the above procedures.

1. Procedure synchronize nodes

To determine the offset of MUMU requires a synchronization of the nodes to synchronize, based on the channel interval or frame, between cattle and node C. figure 4 shows the time dependence between the cattle and the node b and the synchronization process nodes by transmitting a specific message.

As shown in figure 4, item 401 represents a time axis cattle 403, and the position 402 represents time axis node 404. Time axis 401 cattle 403 is divided into frame numbers of cattle (referred to hereinafter as "NCC"). NCC takes values from 0 to 4095 and has duration of 10 MS. Time axis 402 of the node 404 is divided into frame numbers of the node (referred to hereinafter as "LCI"). Like NCC, LCI also accepts values from 0 to 4095 and has duration of 10 MS. Figure 4 NCC and LCI is not synchronized.

The synchronization process node represents a procedure for obtaining information on the time axis 402 of the node 404 by cattle 403. The synchronization of the nodes is performed using the following steps.

Cattle 403 transmits the frame 405 synchronization nodes descending line (IO) to synchronize nodes to a particular node 404 (step a). After reception of the frame 405 synchronization of nodes NL transmitted from cattle 403, the node 404 transmits the frame 406 synchronization nodes ascending line (VL) on cattle 403 in response to the received frame 405 Singh is anizatio nodes NL (stage b). After receiving the frame 406 synchronization nodes VL cattle 403 receives information about the time axis 402 of the node 404 by determining the estimate for the difference of time between the NCC and LCI (phase C).

The following details the steps of the synchronization process nodes.

On stage and cattle 403 enters a temporary value T1 on the time axis 401, where should be transferred to the frame 405 synchronization of nodes NL, frame 405 synchronization of nodes NL and transmits the frame 405 synchronization of IO nodes with the entered time value T1 at node 404. Temporary value T1 is a temporary value, as measured by the 0,250 MS on the time axis 401. For example, in figure 4, the temporary value T1, which is to be transmitted, the frame 405 synchronization of nodes NL, is 40941,250 MS. 40941,250 MS indicates that the frame 405 synchronization of IO nodes is transmitted through 1,250 MS after the time of the beginning of the NCC 4094.

On stage, the node b 404 receives a frame 405 synchronization of nodes NL, passed from cattle 403, and identifies a temporary value T1. Next, the node 404 defines the time value T2 on the time axis 402 representing the time when the adopted frame 405 synchronization of IO nodes. Upon expiration of a predetermined time, the node 404 transmits on cattle 403 frame 406 synchronization nodes VL, which includes a temporary value T3, which represents the point in time to the Yes must be transmitted T1, T2 and the frame 406 synchronization nodes VL. Like T1, time values T2 and T3 represent the time values measured by means of 0.250 MS. For example, it is assumed that T2 is 1492,500 MS and T3 - 1505,000 MS. T2 indicates that the node 404 received frame 405 synchronization of nodes through the IO 2.5 MS after LCI 149. T3 indicates that the node 404 started the transfer frame 406 synchronization nodes VL through 5 MS after LCI 150.

On stage with cattle 403 receives a frame 406 synchronization nodes VL and allocates T2 and T3 from a received frame 406 synchronization nodes VL. Through reception of the frame 406 synchronization nodes VL cattle 403 identifies a temporary value T4 represents the time of his admission. In the cattle 403 can identify T1, T2, T3 and T4.

Cattle 403 can calculate the time the double-pass frame (VDPC) between cattle node 403 and 404, based on T1, T2, T3 and T4. Time the double-pass frame (VDPC) can be computed by

equation (1):

WDPK=T4-T1-(T3-T2).

As shown in equation (1), the double-pass frame can be defined as the amount of time needed to transmit the frame 405 synchronization of IO nodes from cattle 403 to node 404, and the time required for transmission of the frame 406 synchronization nodes VL from node 404 cattle 403.

Cattle 403 can calculate the delay for transmission in one direction (SPAN) by the time the double-pass frame. Those. value, defined as half the time the double-pass frame, as can be assumed equal to the delay in transmission in one direction. From equation (1) delay in transmission in one direction SPAN can be represented

in equation (2):

SPON=[T4-T1-(T3-T2)]/2.

Delay in transmission in one direction, represented by equation (2)shows the time required to transfer a specific frame from cattle 403 to node 404, or from node 404 cattle 403. To assume that the delay in transmission in one direction is equal to 1/2 of the time the double-pass frame, delay in transmission in one direction in the ascending line must be identical to the delay in transmission in one direction down the line. However, in the General case, since the delay in the transmission in one direction in the ascending line is different from the transmission delay in one direction down the line, the delay in transmission in one direction, calculated from equation (2), is an estimate and not an exact value.

Cattle 403 can determine the relationship between the NCC, i.e. the time axis 401 in cattle 403, and LCI, i.e. the time axis 402 at node 404, through the use of time double-pass frame. I.e. T2 becomes the time value of the time delay in transmission in one direction was PEFC is T1. For example, in figure 4 it is noted that T2 in time, when there was a delay in transmission in one direction from T1 (=40941,250)becomes equal 14941,250. If it is assumed that T4 is equal to 33 (T4=33), the delay in transmission in one direction becomes won with 51.75/2. Thus, T2 (=1492,500) on the time axis 402 of the node 404 can be represented by equation (3) on the time axis 401 cattle 403.

Equation (3):

T1(=40941,250)+51,75/2=40967,125.

T2(=40967,125) on the time axis 401 cattle 403, calculated from equation (3)can be expressed as 7,125 through the operation module. The necessity of performing the operation module is connected with the fact, as stated above, that the IAC on the time axis 401 cattle 403 has a value from 0 to 4095. Therefore, the difference between the time axis 402 of the node 404 and the time axis 401 cattle 403 can be calculated from

equation (4):

(time axis node)-(time axis cattle)=1492,5-7,125=1485,375.

So summarizing, equation (4) can be expressed as

equation (5):

(time axis node)-(time axis cattle)=T2-(T1+[T4-T1-(T3-T2)]/2)=1/2(T-T-T4+T1+T3-T2)=1/2(T2-T1)-(T4+T3).

As described above, the difference between the time axis 401 cattle 403 and the time axis 402 of the node 404 is an exact value, when the delay in transmission in one direction down the line is identical to the delay in transmission in one direction in the ascending line. However, in the General case, because detention is ka transmission in one direction down the line is not identical to the delay in transmission in one direction in the ascending line, the difference is not an exact value. In order to solve the problem, the frame synchronization of the nodes NL and frame synchronization of the nodes VL during their transmission is given the highest priority. This measure is designed to consider only pure transmission delay as delay in one direction descending and ascending line by minimizing delays transmission of the frame synchronization of the nodes NL and frame synchronization of the nodes VL. The result is a delay in transmission in one direction down the line may be sufficiently similar to the delay in transmission in one direction in the ascending line.

The temporal relationship between the time axis 402 of the node 404 and the time axis 401 cattle 403, estimated by the synchronization of the nodes is determined in accordance with how closely the delay in transmission in one direction down the line delay when transmitting in one direction in the ascending line. That is, you can determine the correct temporal relationship between the time axis 402 of the node 404 and the time axis 401 cattle 403 even on the basis of the channel interval or based on the frame. In the following description deals with the case when the estimation is correct, based on a channel interval, and a case where the assessment is correct based on the frame. The synchronization process at the fishing can be performed either periodically, either before or after the data transfer.

2. Measurement procedure for smooth transfer of THE service in the service MWMO and the synchronization time data node

In the present invention, it is assumed that synchronization is based on a channel interval or frame between the cattle and the node has already been achieved, when the displacement of MUMU is determined by the measurement error (or difference NSC-NSC) from THE node representing the difference between the moments of time unit of the chip between the nearest channel intervals or frames. Based synchronization channel interval or frame between cattle and node, as described above, can be achieved by synchronization of the nodes. In addition, in the present invention, it is assumed that the corresponding nodes have the same radius of the cell. Therefore, ONE located at the same distance from two hundred, can receive data at the same time, when two cells transmit data simultaneously. Finally, in the following description of the present invention, reference is made only to the questions essential to the understanding of the invention. The description of the case, when two cells have different radii, is not included, as it can be seen as an extension of the scope of the invention.

The synchronization process when cells transmit the same data MUMU, and comply with the Oia each of THE soft transfer service or soft combining synchronized data MUMU, can be performed in the following steps.

Step 1: measure the observed difference time NSC-NSC to determine time information for nodes within one cattle and feed the observed difference time NSC-NSC cattle.

Stage 2: analysis by CRS of temporal dependence between the nodes, based on the observed difference time NSC-NSC obtained in step 1, and determining the offset of MUMU required for nodes Century

Stage 3: submission offset MUMU defined in step 2 to the appropriate nodes In the corresponding TA.

Stage 4: preliminary data transmission to determine the time dependence between the cattle and the node before sending data MUMU, so that the node can transmit data in accordance with displacement of MUMU defined in step 3 (synchronization subscription plane).

Step 5: transfer data MUMU in accordance with the time dependence determined in step 4.

Below details the separate relevant steps with reference to the preferred embodiments of the and the accompanying drawings.

The above stages, together with the above synchronization process nodes to determine the correlation between time points in cattle and points in time in the node In between Crsi node, may be necessary for the above steps and data transmission MUMU. Alternatively, the synchronization process nodes can be made between pre cattle and node regardless of the above steps.

Procedure padded transfer service MWMU the above stages can be divided into method (first embodiment of measurements observed difference time NSC-NSC TA by TA and another method (second embodiment of measurements observed difference time NSC-NSC node by node C.

Below describes in detail the procedure of gentle transmission maintenance MUMU assuming that that is in the field of soft transfer service, where he can simultaneously receive data MUMU from two nodes Century

3. Embodiments of the

3-1. The first variant of execution (observed difference between the moments of time NSC-NSC transmitted from THE cattle)

In accordance with the above steps below presents a description of procedures for soft transfer service in an asynchronous mobile communication system in accordance with a variant implementation of the present invention.

First is a detailed description of step 1, i.e. the dimension of the observed difference time NSC-NSC ONE by ONE to determine time information for a node In the sight of the crystals of the actions of one cattle and feed the measured observable difference time NSC-NSC on THE cattle.

In order to measure the observed difference between the moments of time NSC-NSC THAT from THE cattle can either choose a specific ONE to measure or to determine the amount, taking into account the statistics of the measurement values taken from several THAT, as the observed difference time NSC-NSC. To make specific THAT could measure the observed difference between the moments of time NSC-NSC THAT cattle must choose a specific ONE. Concrete THAT can be selected through the value of the signal-to-noise (referred to hereinafter as "SNR") of the common pilot channel (referred to hereinafter as "PCR"), adopted at THE from node Century I.e. cattle allows ONE to measure the information in a time when cattle transmits data MUMU on many nodes, so THAT the receiving data MUMU from multiple nodes, i.e., ONE for which you want soft transfer service can accept data from MUMU from nodes within the minimum difference between the moments of time. Cattle can choose THE one as defined, located in the area of transmission service by value of SNR the PCR received from the host, and can allow ONE to measure the observed difference between the moments of time NSC-NSC.

The observed difference between the moments of time NSC-NSC TA measured by THE one located in the area of transfer service, where he simultaneously when IMET data from many sites, can be defined as

equation (6):

the observed difference between the moments of time NSC-NSC TA =OFF38400+Tm.

Here it is assumed that the first node and a second node corresponding to the set of nodes To transmit data MUMU on THAT. In equation (6) Tmindicates the offset of the code element signal (hereinafter chip) and can be defined as

equation (7):

Tm=TRxHCKj-TRxHCKi.

The unit of measurement Tmdefined by equation (7), is a chip and has an effective area [0, 1,... 38999]. In equation (7) TRxHCKjis time the beginning of a particular frame of the primary common physical control channel (PAFCO)taken from the jthcells, and TRxHCKirepresents the time of the beginning of the frame POPKO, which SHE took from the ithhoneycomb before TRxHCKj. Assume that jthhoneycomb corresponds to the first node, while the ithhoneycomb corresponds to the second node C. In equation (6) OFF indicates the offset of the unit frame and is defined as

equation (8):

OFF=(NSCj-NSCi) modulo 256.

In equation (8) effective area is OFF [0, 1, ... 255]. In addition, the NSCjrepresents the frame number of POPKU descending line, which SHE took from the jthcell (or the first node In time TRxHCKjand the NSCiis nome is the frame POPKU descending line, which SHE took from the ithhoneycomb (or the second node) at time TRxHCKi. Therefore, TRxHCKjrepresents the point in time of the start of frame corresponding to the NSCjwhile TRxHCKirepresents the point in time of the start of frame corresponding to the NSCi. Select THE one which will measure the observed difference between the moments of time NSC-NSC THAT was described in detail together with a description of the procedures for determining that a particular ONE is located in the area of transfer of service.

THE reporting of the measured observable difference between the moments of time NSC-NSC THAT cattle may additionally provide information on the capacity of the PCR for nodes In a running dimension. Information about the power can be used cattle in the process of determining a specific position between the two nodes, where is THE. Ie, if the power level of the PCR from the first node is higher than the power level of the PCR from the second node b, then cattle can determine what THAT is located closer to the first node than the second node C. This example corresponds to the case when the transmit power of the PCR of the first node is identical to the transmit power of the PCR second node Century When the power levels of the PCR from the nodes differ from each other, as cattle pre has information about different capacity, cattle can determine the position of THE using in which ormatio of transmitted power in addition to power, you took THAT. However, as is an important power receiving DIC THAT it is preferable to assume that, if the levels of the received power of the PCR identical to each other, that is in the field of soft transfer service.

The observed difference between the moments of time NSC-NSC THE one calculated in step 1, is fed to THE cattle, using message control wireless link (referred to hereinafter as "URL"). The observed difference between the moments of time NSC-NSC THE fed to cattle, represents information on the dependence between the values of the time axis (or NSC) nodes Century

Below is a detailed description of phase 2, i.e. determine the temporal dependencies between nodes depending on the NSC values computed in step 1, and define offsets MUMU to be issued on the appropriate nodes of the Century and Also in the description of stage 2, it is assumed that, as the two cells have the same radius of hundred, then the transmission service is defined with a center point located at the same distance from the two nodes Century, I.e. it is assumed that, as the transmit power levels of the two nodes are identical to each other, and the distances from the nodes To also identical to each other. Therefore, the data transmitted by the two nodes with the same power, arrive at THE same time. When two cells have different radii with the t, determining the time of transmission of the same data MUMU can optionally be performed using power from two hundred. Ie, if two cells have different radii, information about the power levels can be further used to determine the point in time data transmission MUMU.

When an observed difference between the moments of time NSC-NSC THAT is specific to THE stage 1, the observed difference between the moments of time NSC-NSC THAT represents the value represented by equation (6). The observed difference between the moments of time NSC-NSC THAT can be defined as the difference between the transmission time of two nodes at a particular point in time and can be represented

equation (9):

the observed difference between the moments of time NSC-NSC TA = time of transmission of node # 1 - time transmission of node # 2.

In equation (9) "time of transfer" means the time axis on the side of the transmission in relation to hundred nodes, represented by the NSC, and can be considered on the basis of the chip. I.e. the time the transfer takes the value from 0 to hwowof the chip. If the torque transmission time has a value from 0 to 38400wowchip (0≤time transfer≤38400wowchip), can be specified that the transfer is in the NSC(1), and if the time of transmission has the t value between Nsch thchip and (NSC+1)hthchip (pwowchip≤time transfer≤(n+1)hwowchip), can be stated that the transfer is done with the NSC(n).

In equation (9) assumes that the jthhundredth is honeycomb No. 1 (or the first node), and assume that ithhundredth is honeycomb No. 2 (or the second node). In this case, OFF(=NSCj-NSCimodulo 256) represents the difference in frames between hundredth No. 1 and hundredth No. 2, and Tmrepresents the difference between adjacent frames cell No. 1 and cell No. 2.

Cattle can select a particular cell for data transmission in the same time as the NSC selected cell. I.e. the AUC, representing the sequence data can be recorded at the NSC, indicating the time of data transmission. Bias MUMU, the difference between a one-room "AUC" data transmission and the time of data transmission from the BS may be determined

equation (10):

bias MUMU=(time transfer - BS)=0.

The data transmitted from cattle on site In accordance with equation (10), is transmitted to the NSC, which has the same magnitude as the corresponding AUC. The NSC has a value from 0 to 4095, and the BS has a value from 0 to 255. Thus, when the NSC is greater than 255, if the remainder is determined by division of the NSC on 256 identical to the AUC, it is determined that h is about the NSC is equal to the AUC.

You can also transfer data from the BS to a particular cell by applying a maximum difference of time, as the amount of displacement of MUMU instead of sending data at the time of the NSC, which has the same value as described in connection with the above method. The amount of displacement of MUMU can be computed by

equation (11):

bias MUMU=(time transfer - AUC)=OFF0 x 38400 + Semenyaka.

In equation (11) OFF0 has a concrete value from 0 to 255 and can be defined using the cattle, and Semenyaka has a value from 0 to 38399 (0≤Semenyaka≤38399) and can also be defined using the cattle. I.e. by identifying specific offset value in selecting a particular node In the can, it is preferable to set the relationship between the AUC for the data and time of transmission of the selected node Century

For the sake of convenience in description, it is assumed that the selected particular hundredth in this case is the first node In (or honeycomb No. 1). I.e. cattle sets AUC, corresponding to the number of data, given the NSC cell # 1 or the first node). As described above, it is assumed that the BS and the NSC installed and have the same magnitude. I.e. cattle defines the transfer of data from the BS, having the same amount in the NSC time cell No. 1.

If you have defined the relationship between the AUC and the NSC for one is the notes, as indicated in connection with the above-described example, the amount of displacement of MUMU representing the relationship between the AUC, i.e. a single-digit number of data to be transmitted to the honeycomb No. 1, for cell No. 2 that share a region transmission service hundredth No. 1, and the NSC, i.e. the time axis of the honeycomb No. 2, can be determined using the observed difference time NSC-NSC cell No. 1 and cell No. 2, adopted on step 1.

When an observed difference between the moments of time NSC-NSC cell No. 1 and cell No. 2 is determined by the OFF38400+Tmas described in connection with the above example, and the relationship between the NSC time transfer cell No. 1 and BS unambiguous non data MUMU is determined using the "time transfer modulo 256 = BS", as described in connection with the above assumption, then the amount of displacement of MUMU for cell No. 2 can be determined

equation (12):

bias MUMU=(time transfer cell No. 2 - AUC) = OFF38400+Tm.

Therefore, in cell No. 1 data having a specific value of AUC, are transmitted to the NSC, which has the same magnitude as and BS, and sauté No. 2, data is transferred at the time of transmission, having a magnitude determined by the sum of the AUC and OFF38400+Tmas shown in equation (12). Since the difference of time between hundredth No. 1 hundredth and No. 2 can be calculated by OFF38400+T in the measurement result in step 1, you can see that the AUC is transmitted from each cell at the same time.

In the General case, when the time transfer is not identical to the BS in cell No. 1, as shown in the above example, and has a predetermined offset, represented by equation (11), the time of transmission of cell No. 2 can be calculated

equation (13):

bias MUMU = (time transfer cell No. 2 - AUC)

= (time transfer cell No. 2 - time transfer cell No. 1) + (time transfer cell No. 1 - AUC)

= (observed difference between the moments of time NSC-NSC between hundredth No. 1 and hundredth No. 2) + (bias MUMU cell No. 1)

= (OFF x 38400 + Tm) + (OFF0 x 38400 + Semenyaka).

According to equation (11) and equation (13) the time to transfer a single AUC of each node is equal to "time transfer cell No. 1 = BS + OFF0 x 38400 + Semenyaka for cell No. 1 and time transfer cell No. 2 = BS + OFF x 38400 + Tm+ OFF0 x 38400 + Semenyaka for cell No. 2. Since the difference of times of transmission between hundredth No. 1 and hundredth No. 2 is equal to "OFF x 38400 + Tm", i.e. as "the time of the transfer cell No. 2 - time transfer cell No. 1 = OFF x 38400 + Tm"that can be understood from the above formula that the same BS are transmitted at the same time.

To summarize, the relationship between the time of transmission with the s in a single node and the BS is determined by equation (10) or equation (11). When given the relationship between the AUC and the time of the transfer, this process may be omitted. If it is determined the correlation between the time of transmission of one cell and the BS, the relationship between the time of transmission of neighboring cells and the AUC determined for sites that are adjacent to one hundredth, through the use of the observed difference time NSC-NSC obtained in step 1 of the temporal dependencies between the frames. For another cell adjacent to that hundredth, the relationship between time of transfer and AUC can be determined by this same process through the use of equation (12) or equation (13).

In the present invention the relationship between the time of transmission and BS is referred to as "bias MUMU". Bias MUMU can be defined by cattle as a result of performing the above process on the honeycomb nodes Century

Below is a detailed description of phase 3 filing offset value of MUMU defined in step 2 to the appropriate nodes and the corresponding TA.

The amount of displacement of MUMU cell (or node), defined by cattle, is transmitted to THE node b by the message, URL and message application part of the site (PCUV), respectively. Bias MUMU, some cattle may be transferred either to the corresponding node, or node, is and which is not transmitted in real time, the data of MUMU, in order to simultaneously control the time of transmission on multiple nodes Century, I.e. to determine for each node At time of data transmission MUMU, subject to synchronization, offset, MUMU, to be enumerated in each cell, previously transmitted to multiple nodes, so they are pre-informed about the bias MUMU. Therefore, the initial offset of MUMU between adjacent nodes, the node uses the offset of MUMU to determine the time of data transmission MUMU in preparation for the transfer of THE service or start of service MUMU. When receiving the offset of MWMU the node and THE determined time of transmission of data in accordance with the amount of displacement of MUMU, thereby allowing to perform soft combining the same data transmitted from multiple cells.

As shown in figure 2, when SHE takes the offset of MUMU (first bias MWMU) for cell # 1 and the offset of MUMU (second bias MWMU) for cell No. 2, the signal received from the cell # 1 in "the NSC(k) + first bias MUMU", and the signal received from the cell # 2 in "the NSC(k) + second bias MUMU"represent the same data. The signals may be soft combined. In the above formulas, k in the NSC(k) can take values from 0 to 4095. Meanwhile, the message to install odenplan the frame of channel data and the message to install the radio link is available for messages URL and message PCUV, used, respectively, in the procedure of the transfer bias, MUMU. Of course, can be changed the message format for transmitting displacements of MUMU on THE node Century

Below is a detailed description of phase 4 (phase synchronization of the subscriber plane) determine the time dependence between the cattle and the node before sending data MUMU, so that the node can transmit data in accordance with displacement of MUMU defined in step 3.

The synchronization process subscriber plane is the process of synchronizing data streams downstream of the selected channel or maintain or restore the current state of synchronization and runs on transport unidirectional broadband channel lur data, i.e. the Protocol between cattle and cattle, and unidirectional transport channel lub data, i.e. the Protocol between cattle and node C. In General, the synchronization process subscriber plane for a particular radio link is performed to synchronize all transport unidirectional data channels for the radio.

Synchronization of the subscriber plane, in fact, is the process of determining the time of transmission to cattle, i.e. time NCC timer cattle, where the corresponding data frame should be copied and transmitted, when cattle property is extended to convey their particular frame of data on THE scheduled NSC node C. This process is described with reference to figure 3. Figure 3 position 301 represents the time of cattle. Cattle, in fact, going to convey AUC(12) within a certain period of time a node In a presented position 303. In order to make such a transfer shall be defined moment in time, when they should be transferred to the corresponding AUC(12). Therefore, as represented by the position 302, cattle passes temporal information about AUC(12) on site In conjunction with the synchronization signal IO. A node In a pre-304 sets the time of start of window revenues (VMEP) and 305 of the end of the box, receipt (VLOOP) by use of the control signal. The window of receipt is established in order to guarantee an optimal period of time during which the node receives a particular message and then performs a stable re-transmit the appropriate message through the appropriate process. When a message is passed to cattle, are received within an appropriate period of time, the node calculates the time 306 receipts (EAP), the difference of time between the time when the transmitted message was received, and WOOP 305. In this case, the EAP has a positive value. The calculated VP is transmitted to cattle, using the synchronization message overhead lines. Based on the EAP in the community of the AI synchronization VL, Cattle determines that the transmission runs fine, and then continuously performs the data transfer. When a message is passed to cattle, is supplied to the node after VLOOP 306, calculated VP has a negative value, and cattle pushes forward transfer AUC(12)based on EAP, thereby transmitting the AUC(12) as represented by the position 303. In the opposite case, i.e. when a message is passed to cattle, comes to LMNOP 304, calculated VP more open admission and cattle delays the transmission of the BS(12), based on the EAP.

3-2. The second option run (measurement site)

In accordance with the above steps the following is a description of the procedure of soft transfer service in an asynchronous mobile communication system in accordance with another variant of implementation of the present invention.

First is a detailed description of step 1, i.e. the dimension of the observed difference time NSC-NSC node by node to determine time information for nodes within one cattle and feed the measured observable difference time NSC-NSC node In cattle.

Relative temporal information between nodes, measured by the node B, i.e. the observed difference between the moments of time NSC-NSC node, is determined by equation (14) is similar to the method of measuring the observed difference IOM is now time NSC-NSC through THAT in the first embodiment.

Equation (14):

The observed difference between the moments of time NSC-NSC node = TRxj-TRxi.

In equation (14) TRxiis time the beginning of the specific channel interval of the primary PCR on the time axis of the node, which measures the observed difference between the moments of time NSC-NSC node, and TRxjrepresents the time that is closest to TRxifrom the number of times the beginning of the channel interval of the primary PCR, taken from cells of the same node Century

As shown in figure 2, position 206 corresponds to the observed difference time NSC-NSC node, measured in cell No. 1. Here TRxicorresponds to the time of the beginning of the transmission channel interval No. 1 with the NSC(3) on the time axis 208 cell No. 1, and TRxjcorresponds to the time of the beginning of the reception channel interval No. 7 with the NSC(15) of the number of blocks of data transmitted from the cell # 2 on the time axis 209 cell No. 1. Another definition of the observed difference time NSC-NSC node will be given with reference to figure 2. TRxjmeasured on the time axis 210 cell No. 2, represents the time when the honeycomb No. 2 begins to take timeslot primary PCR from cell No. 1. Similarly, TRxirepresents the time of the beginning of the channel interval of the primary PCR transferred to one hundredth the 2 at the time, closest to TRxjon the time axis 211 cell No. 2. In the present invention two definitions can be used together. Two definitions provide the same measurement, and the positions 206 and 207 in figure 2 correspond to the values of the measurements. The smallest unit of the observed difference time NSC-NSC node defined by equation (14)is the chip, and its effective area can be defined as[-1280, ... 1279, 1280].

Although the above was the definition of the observed difference time NSC-NSC node In between the channel intervals of the PCR, can also be the definition of the observed difference time NSC-NSC node In between the frames of the PCR. To measure the observed difference time NSC-NSC node In the definition of the difference between the points in time of the beginning of the frame can be given as

equation (15):

the observed difference between the moments of time NSC-NSC node = TRxj- TRxi.

In equation (15) TRxiis time the beginning of a particular frame of the primary PCR on the time axis of the node, which measures the observed difference between the moments of time NSC-NSC node, and TRxjrepresents the time that is closest to TRxifrom the number of times the start frame of the primary PCR, taken from cells of the same node B. Minimum unit n is blademail difference time NSC-NSC node, defined by equation (15)is the chip or unit smaller than the chip, and its effective area can be defined as [-19200,0000 ... 19200,0000] for units of the chip.

In the case of the measurement node, each node can transmit the received power of the PCR with the other nodes In cattle together with the measured value. The reason for sending information about the received power of the PCR is that, when the transmit power levels of the PCR from two hundred differ from each other, the area of transmission service cannot be determined with the center of the TA, located at the same distance from two hundred. In General, the area of the transmission service is defined with a center point at which the levels of the received power from the two neighboring hundred identical to each other. However, when the transmit power levels from two hundred differ from each other, even if THAT is the same distance from two hundred, the levels of the received power of the PCR received from the respective sites, which differ from each other. Although the transmit power levels from two hundred different, the PCR signals from the honeycomb can be received with the same power THAT located in the area of transmission service. This means that, although THAT is located in the area of transfer service, it is located at various distances from two hundred. Thus, it can be seen that is closer to the OTE, with relatively low transmit power. In this case, the honeycomb having a relatively low transmit power is preferably transmitted data MUMU, not two cells transmitted data MUMU at the same time. Therefore, each node can transmit the received power of the PCR is similar to the honeycomb on cattle together with the measured value.

Below is a detailed description of phase 2, i.e. offsetting MUMU to be feeding on each node, based on the ratio between the NSC values computed in step 1, in which the magnitude of the measurement calculated in step 1, provide information about the correlation between the values of the time axis (or NSC) of the respective nodes Century

Description of the method for measuring node is given separately with reference to the case when the observed difference between the moments of time NSC-NSC node is determined as the difference of time between channel spacing PCR and when an observed difference between the moments of time NSC-NSC node is determined as the difference of time between frames of the PCR. In addition, it is assumed that, when the observed difference between the moments of time NSC-NSC node is determined as the difference of time between channel spacing PCR, cattle already informed about the difference between time of transmission of each node In d is the same on the basis of the channel interval through synchronization of the nodes. So cattle can optionally perform the update process synchronization between the two nodes, the difference between the time of transmission which is already known even on the basis of the channel interval in the measurement node Century

Figure 2 shows the time dependence between different cells within the two nodes and the observed difference between the moments of time NSC-NSC. Cattle accepts the observed difference between the moments of time NSC-NSC node, the resulting measurement node, each node C. for Example, figure 2 site # 1 site # 1 and site # 2 site # 2 are adjacent to each other, and cattle accepts the observed difference between the moments of time NSC-NSC node from the node # 1 and node # 2.

The first node 202 receives the PCR transmitted from the cell # 2 of the second node 203, measures the observed difference 206 times NSC-NSC and passes the resulting value to cattle 201. The observed difference between the moments of time NSC-NSC transmitted from the first node 202, defined as the first NSCvarious206. Similarly, the second node 203 receives the PCR transmitted from the cell # 1 of the second node 202, measures the observed difference 207 times NSC-NSC and passes the resulting value to cattle 201. The observed difference between the moments of time NSC-NSC transmitted from the second node 203 will be determined as the second NSCvarious207.

Figure 2 position 208 is predstavljaet NSC torque transmission time, when the honeycomb No. 1 starts the transmission of the channel interval of the PCR, and the position 209 represents the time when the honeycomb No. 1 starts receiving a channel interval of the PCR from cell No. 2. In addition, the position 211 NSC is the time of the transfer, when the honeycomb No. 2 starts the transmission channel of the PCR interval, and the position 210 represents the time when the honeycomb No. 2 starts receiving a channel interval of the PCR from cell No. 1.

Therefore, in figure 2 the first NSCvariousmeasured by the first node 202 may be measured as the amount represented by the position 206, while the second NSCvariousmeasured by the second node 203 can be measured as the amount represented by the position 207.

As cattle 201, as described above, a known temporal relationship between hundredth No. 1 and hundredth No. 2 even on the basis of the channel interval, we can assume in figure 2 that cattle 201 informieren that timeslot No. 1 NSC(3) cell No. 1 is synchronized with a channel spacing No. 7 NSC(15) cell No. 2. Therefore, cattle 201 may perform a more sophisticated synchronization point of time of transmission through the use of the first NSCvarious206, measured and transmitted by the first node 202 and the second NSCvarious207, measured and transmitted by the second node 203.

Figure 2 time axis 208 of the cell # 1 and the time axis 211 cell # 2 is not synchronized with each other. I.e. channel online is tearing No. 1 NSC(3) on the time axis 208 is not synchronized correctly with channel interval No. 7 NSC(15) on the time axis 211. Timeslot number 7 NSC(15) ahead of timeslot number 1 NSC(3) on the time axis. I.e. receiving a channel interval No. 1 NSC(3) hundredth No. 1 begins at the point in time when the transmission channel interval No. 7 NSC(15) hundredth No. 2 was completed by about half.

The first NSCvarious206 and the second NSCvarious207, measured by the node B, and then transferred to cattle 201 may reflect the difference between the time interval between channel No. 7 NSC(15) from the cell # 2 and channel interval No. 1 NSC(3) from cell No. 1.

Equation (16)

Average 1 = (first NSCvariousthe second NSCvarious)/2

Equation (17)

SREDNEE = (second NSCvariousthe first NSCvarious)/2

When determining equations (16) and equation (17), the relationship between the time of transmission nodes can be correctly described using the mean values. I.e. if cell No. 1 time of the beginning of the transmission, meaning the time when he was actually transmitted timeslot number 7 NSC(15) from cell No. 2, can be defined as "the time of the beginning of the channel interval No. 1 NSC(3) + mean 1". In the case of figure 2, as the average 1 has a negative value, timeslot number 7 NSC(15) from cell No. 2 begins with average value 1 to channel interval No. 1 NSC(3) from cell No. 1.

Alternatively, from the point of observation cell No. 2, when compared with a channel in which arvalem No. 7 NSC(15) from cell No. 2, timeslot number 1 NSC(3) from cell No. 1 can be defined as "the time of the beginning of the channel interval 7 NSC(15) + SREDNEE". In the case of figure 2, as SREDNEE has a positive value, timeslot number 7 NSC(15) from cell No. 2 begins with values SREDNEE after channel interval No. 1 NSC(3) from cell No. 1 202.

Therefore, the process of establishing the relationship between the NSC one node In and AUC data transmission and the subsequent establishment of the relationship between the NSC and the AUC of the next node, as shown in the description of the first variant of implementation, can be described as the process of using mean values.

Suppose that the relationship between the NSC and the AUC cell No. 1 is installed

equation (18):

bias MUMU for cell No. 1 = (point in time of the beginning of cell No. 1 - AUC) = OFF0 x 38400 + Semenyaka.

The relationship between the NSC and the AUC cell No. 2 can be determined using the average value as shown in equation (18). Figure 2 Raman 201, as previously previously informed that the synchronization between channel interval No. 1 NSC(3) from cell # 1 and channel spacing No. 7 NSC(15) from cell No. 2 was even made on the basis of the channel interval according to the time axis 208 and the time axis 211.

I.e. cattle 201 previously informed of what

time transfer cell No. 2 - point lying is no transfer cell No. 1 = channel interval No. 7 NSC(15) - timeslot number 1 NSC(3) = timeslot number 6 + frame No. 12

= 6 x 2560 + 12 x 38400 chips.

The synchronization information may, however, be a mistake. Therefore, it is possible to obtain a correct synchronization information on the basis of the chip through the use of averages. It is defined as

equation (19):

time transfer cell No. 2 - time transfer cell No. 1 = 6 x 2560 + 12 x 38400 chips + SREDNEE = 6 2560 x + 12 x 38400 chips +(second NSCvariousthe first NSCvarious)/2.

Therefore, the amount of displacement of MUMU for cell No. 2, i.e. the expression of the relationship between the AUC and the time of transmission of cell No. 2 can be determined

equation (20):

bias MUMU for cell No. 2 = (time transfer cell No. 2 - BS) = (time of transmission of cell No. 2 - time transfer cell No. 1) + (time transfer cell No. 1 - AUC) = (6 x 2560 + 12 x 38400 chips + (second NSCvariousthe first NSCvarious)/2 + (OFF0 x 38400 + Semenyaka).

From equation (20) implies that, if it is determined the correlation between the time of transmission of specific cell (cell No. 1 in equation 20) and the AUC, the relationship between the time of transmission of the other neighboring cells and AUC can be determined using the relationship between time of transmission of a particular cell (or cell # 1) and the AUC.

When an observed difference between the moments of time NSC-NSC node To determine aetsa as the difference of time between frames OPK, it is assumed that cattle are already informed about the difference between time of transmission of each node In even on the base frame by means of synchronization of the nodes.

So cattle can optionally perform the update process synchronization between the two nodes, the difference between the time of transmission which is already known even on the basis of the frame by measuring node Century, Its detailed description is similar to the case when the observed difference between the moments of time NSC-NSC node is determined as the difference of time between channel spacing PCR. The resulting expression is given

equation (21):

bias MUMU for cell No. 2 = (time transfer cell No. 2 - BS) = (time of transmission of cell No. 2 - time transfer cell No. 1) + (time transfer cell No. 1 - AUC) = (HR difference between the time of transmission of the cell # 2 and the time of transmission of cell No. 1) + (second NSCvariousthe first NSCvarious)/2 + (OFF0 x 38400 + Semenyaka).

In equation (21) assumes that cattle is already known (HR difference between the time of transmission of the cell # 2 and the time of transmission of cell No. 1) in the synchronization of the nodes. In equation (21) of the first NSCrasnikand the second NSCrasniki.e. the observed difference between the moments of time NSC-NSC measured by each node In predstavlyaet the difference between the time of the beginning of the frame in a cell and the time of the beginning, closest to the time of the beginning of the frame in sautéed number of frames OPK taken from the same cell. In equation (21) assumes that the difference between the time of transmission of cell No. 1 and BS pre-defined as (OFF0 x 38400 + Semenyaka).

Stage 3 and stage 4 in the second embodiment is identical to stage 3 and stage 4 of the first variant execution, so their detailed description is not repeated.

Detailed description of cattle, a node In a and THAT in accordance with the above procedures is given below with reference to the accompanying drawings.

4. The principle of operation of embodiments of the invention

4-1. The principle of operation of the first variant embodiment of the invention

Figure 5 shows the sequence diagram of signals illustrating a method of synchronizing time data transmission MUMU through node depending on the value of the measure observed difference time NSC-NSC TA from the TA in accordance with the embodiment of the present invention.

As shown in figure 5, cattle sends a request for measurement of a specific PCR THAT through the use of messages URL control measurement in step 501. I.e. cattle selects THE one located in the area of transmission service as a specific ONE that will perform the measurement, and then sends a request to the measurement of DIC to select the config THAT so SHE performs a measurement operation. As described above, cattle can choose a specific ONE and request the selected ONE to perform measurements. Alternatively, when the measurement of the displacement of MUMU need to determine the time data in the node during data transmission MUMU, bias MUMU can be determined using statistical difference values times the NSC-NSC THAT reported from several TA. So it is not necessary to determine whether to perform transmission service on a specific ONE. However, in order to send a request for a measurement on a particular ONE is selected, located in the area of transfer of service.

After receiving the message, the URL management dimension THAT measures, at step 502, the value of SNR the PCR and transmits the measured SNR value of the PCR in cattle by means of the message the URL of the report on the measurement. Cattle takes the measured value of the SNR of the PCR from THE specific and determines based on the measured SNR of the PCR, is there a specific ONE related to transmission service. If it determines that a particular ONE is located in the area of transfer service, cattle can perform on stage 503 synchronizing nodes in order to obtain the time information of the node associated with the transfer of a specific TA. The synchronization of the nodes may be within the and at one stage or independently performed independently determine displacement of MUMU to determine the time of data transmission MUMU node C. I.e. the synchronization of the nodes can be performed before the measurement process to determine the offset of MUMU. Cattle can obtain the time information of the node by means of the procedure of synchronization of nodes with an accuracy of about 0,125 MS.

In synchronization nodes of cattle transmits its own temporal information and the NCC(T1) to the corresponding node In the message, the synchronization of IO nodes. The corresponding node includes a transmission process on cattle message synchronization nodes VL, which includes temporal information (T2, expressed through LCI)indicating the time when the received synchronization message nodes NL and temporal information (T3)indicating the time when the message is sent to the synchronization of the nodes VL.

At step 504 cattle passes the message set the URL of the management dimension to request measurement of the difference of the NSC on THE one located in the area of transmission service. After receiving the message, the URL management dimension THAT measures the observed difference between the moments of time NSC-NSC and then passes to step 505 of the measured observable difference between the moments of time NSC-NSC THAT cattle using a report message about the measurement. Cattle then calculates the offset time data transmission MUMU between related nodes by using the observed difference is of omental time NSC-NSC TA from the TA and the observed difference time NSC-NSC measured during synchronization of the nodes. As described above, for the reference cell (or node), the frame data or time data which most behind, the difference between the NSC measured for the corresponding nodes In through THAT, and the NSC reference cell is set as the offset value of MUMU corresponding cell.

At step 507 cattle passes the calculated amount of displacement of MUMU on the corresponding node through the use of messages PCUV, for example, a request message to install the radio. After receiving the offset of MUMU from cattle node In preparing for determining the point in time transmission of multimedia data in accordance with the amount of displacement of MUMU and passes to step 508 response message to install radio in cattle in response to the request message to install the radio.

At step 509 cattle informs ONE about a certain amount of displacement of MUMU through the use of messages for the installation of one-way radio data transmission or message the URL for the installation of one-way radio data transmission. THE normal mode takes the amount of displacement of MUMU from cattle and transmits at step 510 the message that the installation is complete a one-way radio data transmission to cattle, after the installation is complete, or return to source the condition for the corresponding one-way radio data transmission for a multicast or broadcast transmission. If the synchronization point of time of transmission because of the soft transfer service is performed on site In and THAT, based on the amount of displacement of MUMU, at step 511, the synchronization procedure of the subscriber plane occurs between cattle and node C. the synchronization Procedure of the subscriber plane is performed using messages sync IO, including the AUC for a particular data frame, and message synchronization overhead lines, including RR for specifying the difference between the time when the data frame transmission received at the node, and VLOOP and BS included in the received frame data. This synchronization procedure the subscriber plane is performed to synchronize the time of a data frame transmission. Finally, cattle, after receiving the response message for the installation of the radio link from the node and the message that the installation is complete unidirectional radio transmission of data from ONE begins to transmit the multimedia streaming data MUMU for unidirectional radio data transmission for a multicast or broadcast transmission after synchronization is complete, the subscriber plane.

Figure 6-8 presents a flowchart illustrating the principle of operation of a node In cattle and TA, respectively, according to a variant implementation of the present invention, respectively.

First will be described the principle of action the I node with reference to Fig.6. At step 601, the node b determines, is the request message for the installation of the radio link from cattle. If you receive a request message to install the radio, then at step 602, the node receives the synchronization message of the IO nodes from cattle and then performs a series of operations for synchronization of nodes to inform cattle about his time information through the use of message synchronization nodes VL. At step 603, the node allocates the amount of displacement of MUMU from the received request message for the installation of radio and applies the selected offset MUMU for the process installation time transmission node for the corresponding multimedia streaming. After the completion of the reconfiguration of the radio link for MUMU in accordance with the amount of displacement of MUMU, the node configures the request message to install the radio link for the transmission of information at step 604. After that, at step 605, the node transmits the configured error message prompted to install the radio on cattle, thereby informing cattle on completion of the installation process time transmission node for the corresponding multimedia streaming. Finally, at step 606, the node transmits a synchronization message overhead lines, including EAP and the accepted information of the BS, on cattle for synchronization of frames between the cattle and the scrap Century Meanwhile, the node performs a synchronization procedure of the subscriber plane and then transmits the data MUMU taken from cattle at the time defined in accordance with the amount of displacement of MUMU defined by cattle.

The following describes the principle of cattle with reference to Fig.7. At step 701 cattle passes the message to the URL management measurement on THAT. Message URL management dimension represents a set of messages that allows corresponding to THE measured SNR of the PCR. At step 702 cattle accepts the message, the URL of the report on the measurement, including the value of the SNR of the PCR, the measured ONE. At step 703 cattle determines from the accepted values of SNR the PCR, is THE one who conveyed the message the URL of the report on the measurement, the transmission service. If you need transmission service for THAT, then at step 704 cattle transmits the synchronization message to the IO nodes on the node for obtaining temporal information of the node associated with the service. Next, cattle performs a synchronization procedure of the nodes through message reception synchronization of the nodes VL with time information from the node C. in Addition, at step 705 cattle passes the message to control the dimension of the TA, located in the area of transfer of service, so that it measures the observed difference between the moments of time NSC-NSC. At step 706 cattle accepts the message is their report on the measurement, includes the observed difference between the moments of time NSC-NSC measured. At step 707 cattle determines the amount of displacement of MUMU each cell through the use of accepted the observed difference time NSC-NSC and the observed difference time NSC-NSC measured during synchronization of the nodes. At step 708 cattle passes the calculated amount of displacement of MUMU to the corresponding node using the message PCUV prompted to install the radio. The node b determines the point in time streaming multimedia MUMU using the offset value of MUMU from cattle. If defined point in time data transmission MUMU, the node transmits a request message to install radio on cattle. At step 709 cattle accepts the request message to install the radio link transmitted from node C. At step 710 cattle transmits the amount of displacement of MUMU to the corresponding ONE with the message the URL of reconfiguration unidirectional channel data. After receiving the offset of MUMU THAT is preparing to receive MUMU. If the preparation for receiving MUMU completed, that informs cattle on the completion of preparation for reception of MUMU through the use of messages that the installation is complete a one-way radio data transmission. At step 711 cattle accepts THE message that the installation is complete adsonar the slow channel data as a message that the installation is complete or return to its original state for the corresponding one-way radio data transmission. Finally, at step 712 cattle transmits the synchronization message IO with the AUC on the node for frame synchronization with the node C. in Addition, cattle receives from a node In the synchronization message overhead line, which includes information about the EAP and adopted by the AUC. Cattle can synchronize subscriber plane using EAP from a received message synchronization overhead lines. After synchronization of the subscriber plane cattle transmits data MUMU at the time of transfer, determined in accordance with the magnitude of the displacement of MUMU.

Below will be described the principle of TA with reference to Fig. At step 801 THAT receives the control message by the measurement from the corresponding Raman spectra. If accepted, the message management dimension, then at step 802 THAT measures the SNR value of the PCR in accordance with the set information in the message management measurement and then transmits the measured value of the SNR of the PCR to the appropriate cattle through the use of message the URL of the report on the measurement. If cattle determines from the value of the SNR of the PCR that is related to transmission service, that takes from cattle message the URL of the management dimension to request measurement of the observed difference time NSC-NSC at step 803. THE measures of the observed difference between the moments of time NSC-NSC in response to the message, the URL management measurement and then informs on the stage 804 cattle on the measured observable difference time NSC-NSC through the use of message the URL of the report on the measurement. Cattle then determines the amount of displacement of MUMU of the observed difference time NSC-NSC from TA and transmits a certain amount of displacement of MUMU on THAT together with the message on the reconfiguration of the radio link. At step 805 THAT takes a message to install a one-way radio data transmission with the amount of displacement of MUMU. If the amount of displacement of MUMU transmitted from cattle, is received normally, then at step 806 THAT informs cattle of the normal reception of the shift value of MUMU through the use of messages that the installation is complete a one-way radio data transmission, thereby completing the preparation for receiving services MUMU. After that, SHE manages the time of the beginning of reception of frame data to the stream data transmitted from the node B, by using the accepted value of the offset of MUMU, thereby minimizing the loss of received data and allowing you to perform soft combining.

4-2. The principle of operation according to the second variant embodiment of the invention

The present invention also provides a way to synchronize time streaming data MUMU in the node by using the observed difference time NSC-NSC calculated by the synchronization process nodes, and the observed difference time NSC-NSC measured by node C. Method sync is the time of transmission of the node relates to a method of using the observed difference time NSC-NSC the measured node, instead of the observed difference time NSC-NSC measured TA, and a brief description of which is given below.

In the second embodiment of the present invention cattle performs the synchronization process nodes in order to obtain temporal information for multiple nodes Century as a result of this process cattle can obtain the time information of the node with an accuracy of about 0,125 MS. After that cattle transmits the observed difference between the moments of time NSC-NSC measured by each node using the message PCUV request to start measuring. Cattle calculates the amount of displacement of MUMU for all nodes In the multicast group, based on the observed difference time NSC-NSC measured and transmitted by the nodes, and the observed difference time NSC-NSC calculated in the synchronization process nodes. Cattle calculates based on the chip offset of MUMU for each node based on the received values of observed difference time NSC-NSC as follows.

First node In the frame data or the time of transmission of which the most behind, is set as the reference node Century After cattle calculates the difference between the observed difference between the moments of time NSC-NSC measured reference node, and the observed difference between the moments of time NSC-NSC, change the military each node In a, and determines the average value of the difference as an offset value of MUMU for the corresponding node C. the reason for the choice of the method of the delay time of the transmission of individual node based on the reference node, the time data which is most behind is to reduce data loss that can occur if the time data is moving forward. After that cattle performs the synchronization process subscriber plane for each cell through the use of personnel Protocol and then transmits the streaming data MUMU in accordance with the amount of displacement of MUMU for individual cells defined in the previous step.

The second option execution allows not only the synchronization between the nodes associated with the transfer of a specific ONE, but also the synchronization of all nodes included in the multicast scope within a single node C. figure 9 presents the sequence diagram of signals illustrating the method of synchronization time transmitting node based on the measured value of the observed difference time NSC-NSC node In a node In accordance with another embodiment of the present invention. As shown in Fig.9, cattle performs on stage 901 synchronising nodes with the aim of gaining the temporal information of the node, associated with the transmission service. Cattle can obtain the time information of the corresponding node In through synchronization of nodes with an accuracy of about 0,125 MS. During synchronization of the nodes of cattle transmits its own temporal information and the NCC(T1) to the corresponding node In conjunction with the synchronization message node NL. The node includes a transmission process on cattle message synchronization nodes VL, which includes temporal information (T2, expressed through LCI)indicating the time when the received synchronization message nodes NL and temporal information (T3)indicating the time when the message is sent to the synchronization of the nodes VL. If you have completed the procedure for synchronization of the nodes, cattle issues a command to all nodes In the dimension of the observed difference time NSC-NSC by sending a message to PCUV General request to start the measurement at step 902. Upon receipt of a message PCUV General query to start measuring from cattle, each node measures the observed difference between the moments of time NSC-NSC. If you have completed the measurement of the observed difference time NSC-NSC, the node transmits the measured observable difference between the moments of time NSC-NSC on cattle. At step 903 cattle takes the total response message at the start of the measurement, including the observed difference of the moments of the belts NSC-NSC measured all nodes Century cattle calculates the offset of MUMU for each node, based on the adopted General response message to start measuring. That is, at step 904 cattle calculates the amount of displacement of MUMU for each node, based on the observed difference time NSC-NSC calculated by the synchronization process nodes, and the observed difference time NSC-NSC measured and transmitted by the node C.

At step 905 cattle passes the calculated amount of displacement of MUMU to the corresponding node using the message PCUV, for example, a request message to install the radio. As was shown above, cattle can transmit information about the amount of displacement of MUMU among multiple nodes In all of the several hundred. I.e. as even honeycomb, where the data MWMU not transmitted at the present time, may determine the time of data transmission MUMU-dependent offset value of MUMU, cattle can transmit a predetermined bias MUMU several hundred. Of course, the transfer method bias, MUMU from cattle on site In or THAT can be modified in the meaning of the message PCUV and message URL. In addition, the offset of MUMU can be transferred either sequentially or simultaneously on the site and In THE.

The node B, after receiving the offset of MUMU from cattle, determines the time of transmission of multimedia data in accordance with adopted the nd offset MUMU. If it is determined transmission data MUMU, then at step 906, the node sends a reply message to install radio on cattle. At step 907 cattle informs ONE about a certain amount of displacement of MUMU through the use of messages for the installation of one-way radio data transmission or message the URL for the installation of one-way radio data transmission. If the amount of displacement of MUMU normally adopted, that performs the set or reset the time of transmission on the corresponding one-way radio data transmission for a multicast or broadcast transmission. If you have completed the install or reset time of the transfer, it sends the message that the installation is complete a one-way radio data transmission to cattle at step 908. At step 909 cattle performs a synchronization procedure of the subscriber plane with node C. In the synchronization procedure, the user plane synchronization message IO, including the AUC for a particular data frame, and the synchronization message overhead lines, including EAP, indicating the difference between the time when the received frame data transmission to the node B, and UNEP, and BS included in the received frame data, are used between cattle and node C. This procedure synchronization subscription to the plane is d the I the synchronization time transmitting data frames. Finally, cattle, after receiving the response message for the installation of the radio link from the node and the message that the installation is complete unidirectional radio transmission of data from ONE begins sending media stream data of MUMU for unidirectional radio data transmission for a multicast or broadcast transmission.

Figure 10-12 presents a flowchart illustrating the principle of operation of a node In cattle and TA, respectively, according to another variant implementation of the present invention, respectively.

First will be described the principle of operation of a node In a with reference to figure 10. At step 1001, the node performs a synchronization procedure of the sites with cattle. If the synchronization of the nodes is completed, then at step 1002, the node receives a General query message to start measuring from cattle. Adopted by the General query message at the start of measurement is a set of messages to measure the observed difference time NSC-NSC between nodes Century, the Node measures the observed difference between the moments of time NSC-NSC between neighboring nodes and transmits the measured observable difference between the moments of time NSC-NSC cattle together with the General response message at the start of the measurement at step 1003. At step 1004, the node b determines, is the request message for the installation of the radio link from cattle. If at step 1004 it is determined that a message was received request is and the setting of the radio link, at step 1005, the node allocates the amount of displacement of MUMU defined by the cattle from the received request message to install the radio, and then applies the selected offset MUMU in the process of determining the time of transmission of the node for the corresponding multimedia data stream. The node configures at step 1006 the response message to install the radio and then transmits the configured response message to install radio on cattle at step 1007, thereby informing cattle on the completion of the process of determining the time of transmission of the node for the corresponding multimedia data stream. The following describes the principle of cattle with reference to 11. At step 1101 cattle performs a synchronization procedure nodes with predefined nodes Century At step 1102 cattle transmits a message PCUV General request to start a measurement on the nodes Century message Sent PCOV is the set of messages to request the measurement node, receiving a message, the observed difference time NSC-NSC between its neighboring nodes Century Nodes, upon receipt of a message PCUV General query to start measuring, measure the observed difference between the moments of time NSC-NSC and then transmit the measured observable difference between the moments of time NSC-NSC cattle using a common response within the statutory launch the measurements. At step 1103 cattle accepts the observed difference between the moments of time NSC-NSC measured by the node B, using a General response message to start measuring. At step 1104 cattle determines the amount of displacement of MUMU, depending on the accepted value of the measure observed difference time NSC-NSC. At step 1105 cattle transmits a certain amount of displacement of MUMU on the node through the use of messages PCUV, such as a request message to install the radio. The node then sets or returns to its original state one-way radio data transmission media in accordance with the amount of displacement of MUMU. If the installation or the reset is completed, the node sends a reply message to install radio on cattle, and cattle receives a response message to the radio installation at step 1106. Cattle passes the amount of displacement of MUMU on THE message, the URL for the installation of one-way radio data transmission at step 1107 and receives a completion message is set or reset for the corresponding one-way radio data transmission for MUMU at step 1108.

Next will be described the principle of TA with reference to Fig. At step 1201 THAT takes the amount of displacement of MUMU defined by cattle message on installation and the ku one-way radio data transmission. After you install or reset one-way radio data transmission in accordance with the amount of displacement of MUMU, at step 1202 THAT informs CRS that the installation is complete or return to the original state of the corresponding one-way radio data transmission by using a message that the installation is complete one-way radio data transmission, thereby completing the preparation for receiving services MUMU.

4-3. Other examples of the first variant embodiment of the invention

In the present invention, the method of synchronization time data transmission MUMU node uses the observed interference of times NSC-NSC calculated in the chips using THE one located in the area of transfer service, by allocating the NSC of the PCR transmitted from each node Century Determined that enters the field of transmission service, if there are two or more wireless links with the SNR value of the PCR is higher than a predefined value (see 3GPP specification TS25.101 chap 8.7.1, 8.7.2), through the use of message set the URL of the management measure for measuring individual values of SNR the PCR. Cattle passes the message set the URL of the management dimension to request measurement of the difference of the NSC on THE one located in the area of transfer service is I, thus taking the measured value of the observed difference time NSC-NSC between linked cells using the message the URL of the measurement request. Cattle determines the amount of displacement of MUMU individual cells, depending on the received measured values of the observed difference time NSC-NSC THAT in accordance with the above formulas. Cattle passes a certain threshold correction of the NSC on the appropriate ONE using the message URL. After that cattle performs the synchronization process subscriber plane on an individual cell through the use of personnel of the Protocol, and then transmits the streaming data MUMU in accordance with the magnitude of the correction NSC individual cells defined in the previous step. THE one which will measure the observed difference between the moments of time NSC-NSC THAT can be determined based on the measurement of the PCR reported by the node B, as described above. The number THAT can be one or more. Statistically calculated the observed difference between the moments of time NSC-NSC SHE received from a specific ONE, and it can be used to determine the observed difference time NSC-NSC TA to be used to synchronize the time of transmission of node C. in Addition, even when the displacement of MUMU is determined by with tistichesky calculated the observed differences moments of time NSC-NSC taken from a few THAT a certain offset to MUMU is calculated for a few hundred and then passed to several hundred.

For example, it is assumed that, when a certain number THAT is equal to N, then the observed difference between the moments of time NSC-NSC SHE received from each ONE is defined as an observable difference between(i) the time the NSC THE NSC. Further assume that the parameter i has a value from 1 to N, and the observed difference between(i) the time the NSC-NSC THAT represents the measured value of the observed difference time NSC-NSC SHE received from the iwowTA. In this case, the statistically determined the magnitude of the observed difference time NSC-NSC THAT can be defined

equation (22):

the observed difference between the moments of time NSC-NSC TA = 1/N x [observed difference(1) time NSC-NSC THAT + the observed difference(2) times the NSC-NSC TA + ... + an observed difference(N) time NSC-NSC TA].

As another method, Raman stores statistical information about the observed differences moments of time NSC-NSC THAT transmitted from THE one that perform the transfer between two cells using the selected channel, and then transmits the data MUMU using statistical values stored in it, without the extra dimensions by ONE.

Cattle pic is constantly stores information about the observed differences moments of time NSC-NSC THAT transmitted at the moment one THAT performs transmission service between hundredth No. 1 and hundredth No. 2. Specifically, when the transfer of one between THE hundredth No. 1 hundredth and No. 2, THAT measures the observed difference between the moments of time NSC-NSC or THE observed difference between the moments of time NCC-NSC and then transmits the measured value to cattle. The observed difference between the moments of time NCC-NSC THAT represents the AUC difference data sent from the cell (for example cell No. 1), which is currently installed wireless link, and the NSC cell No. 2, to which must be added the wireless link, and the NSC cell # 1 and the NSC cell No. 2 can be obtained through use of the NCC, NSC cell No. 1. Therefore, the observed difference between the moments of time NCC-NSC THAT can be analyzed as information about the observed difference time NSC-NSC. If the observed difference time NSC-NSC THAT is accepted from one THAT the cattle can modify information about an existing observable difference time NSC-NSC THAT, as determined

equation (23):

the observed difference(0 statistical) moments of time NSC-NSC TA = t x (the observed difference(statistic 1) time NSC-NSC TA) + (1-t) x (the observed difference(new) time NSC-NSC TA).

In equation (23) "t" has a value from 0 to 1 and can be predelena cattle. The observed difference(new) time NSC-NSC THAT is a accept the observed difference between the moments of time NSC THE NSC, and the observed difference(statistic 1) time NSC-NSC THAT represents a previously stored the observed difference between the moments of time NSC-NSC. In the cattle can get the observed difference(statistical 0) times the NSC THE NSC, and the node stores the observed difference(0 statistical) moments of time NSC-NSC as THE observed difference between the moments of time NSC-NSC. Stored the observed difference between the moments of time NSC-NSC THAT can be used as the magnitude of the observed difference time NSC-NSC THE synchronization of nodes for services MUMU.

5. The transmitter node

On Fig depicts the design of the transmitter node according to the embodiment of the present invention. As shown in Fig, the node In the receiver 1301 packet data MUMU receives the data packets, MUMU from cattle. If the AUC data packet, MUMU equal AUC=k, then the NSC frame POPKO, where the transmission of the data packet, MUMU equal to the NSC=k+OFF, and the time delay between the time the start of frame, MUMU and time of the beginning of the frame POPKU should be equal to Tm. In this case, OFF and Tmcomputed using the calculator 1303 HR delay and chip time delay is, based on the information about the offset of MUMU in accordance with equation (24) and equation (25) below.

Equation (24):

Equation (25):

Tm= offset of MUMU - OFF x 38400

In equation (24)means the maximum integer less than or equal to a specific value of "x".

The calculator 1303 HR delay and chip delay applies based on the frame time delay of the data packet, MUMU-based frame delay 1305, and based on chip time delay of the data packet, MUMU - based chip delay 1329. Based on the frame time delay applied to based on the frame delay 1305, is set such that the transmission of the frame MUMU can start at the NSC=k=OFF, while based on chip time delays applied to based on chip delay 1329, is set such that the transmission of the frame MUMU can begin in Tmchip-time after time began POPKU with NSC=k+OFF.

Package data MUMU taken from cattle that is fed to the channel encoder 1307 using based on the frame delay 1305 after calculated based on the frame time delay. The output of the channel encoder 1307 processed by the correlator 1309 rate and interleaver 1311, and then is split into in-phase (I) bit stream and a quadrature phase (Q) the flow of bits through the serial-to-parallel (S/P) Converter 1315 for the formation of a complex stream of characters. The signals I and Q streams of bits multiplied by the expander 1317 on orthogonal code with a variable coefficient of expansion (OPCR) COPCRwith a chip rate for the extension. From the output of the expander 1317 signal Q-bit stream is multiplied by the multiplier 1321 j and converted to the imaginary signal, and the output of multiplier 1321 added to the I signal-flow of bits through the adder 1319, forming a complex signal with a chip rate. The integrated output signal of the adder 1319 multiplied by scramblase codescramblein the scrambler 1331 after based on chip time delay, calculated based on the chip delay 1329, based on POPKU. The output signal of the scrambler 1331 is multiplied by the gain of the channel through multiplier 1333 and then modulated by the modulator 1335. The output signal of the modulator 1335 converted to radio frequency (RF) signal processor 1337 and then transmitted RF antenna 1339.

In the synchronization procedure, the subscriber plane value of Tthe entrythat means the time at which the message sync IO, taken by the receiver 1301 packet data MUMU served on the transmitter 1323 PG. In addition, the AUC included in the synchronization message IO, served on the determinant 1327 LTOA_MBMS. The determinant 1327 LTOA_MBMS determines the amount LTOA_MBMS for the NSC, the appropriate adopted AUC, based n the accepted value of the AUC and the offset of MUMU, taken from cattle message PCOV. Value LTOA_MBMS represents the maximum time offset of MUMU must do, in order to transmit data from the BS+smesheniem. Value LTOA_MBMS is determined in accordance with the interval between samples (UTI), or the basic unit of transmission data, and the PULSE is equal to one of values: 10 MS, 20 MS, 40 MS and 80 MS. That is, when the PULSE more value LTOA_MBMS should be more. Value LTOA_MBMS represents a time interval during which you must enter data with the accepted value of the AUC, so that they can be transferred from the relevant NSC(BS+smesheniem). Thus, if the PULSE is long, the data should be received in advance, in order that they were passed through the interleaver 1311 in the required time. Interleaver 1311 punctuates data by IMP. Thus, if the PULSE is greater than 10 MS, for example, if the PULSE is 20 MS, the value LTOA_MBMS must be installed by an amount which is greater than 10 MS, considering the delay of the data interleaver 1311 before the NSC (i.e. AUC+smesheniem), when it should be transferred to the corresponding BS. Value LTOA_MBMS defined identifier 1327 LTOA_MBMS served on the transmitter 1323 PG. The transmitter 1323 EAP specifies the value of the EAP, based on the accepted value of Tthe entrythe value LTOA_MBMS and size of WOOP, RA is her adopted using messages PCOV. The value of VP is determined

equation (26):

VP = LTOA_MBMS - WOOP - Tthe entry.

A certain amount of VP is transmitted to cattle by means of the transmitter 1325 EAP message, the synchronization overhead lines.

As was shown above, in an asynchronous mobile communication system supporting the service MUMU when SHE moves into an area where it can receive data from multiple nodes, the present invention provides THE soft transfer. Therefore, even if the subscriber of MUMU moves from the present cell to a new cell, the present invention provides a stable subscriber service MUMU. In addition, when it is in transmission service, the present invention allows ONE to perform soft combining data received from multiple nodes, thereby reducing the transmit power of node C. In the present invention contributes to the improvement of output power.

SUBSTANCE: proposed method is characterized in that additional links are organized in network and provision is made for transferring sync signals in backup driving network component, output signals of the latter being generated bypassing internal generator from sync signals arriving from last first-priority component nn and from last second-priority component mm. Sync signal arriving from main sync signal supply is conveyed in series over network through backup driving network component bypassing internal generator; variation (reduction) in quality level of sync signals being used is entered in status message of STM-N heading. As a result, using backup path running to main driving component through m components does not cause closed-circuit synchronization.

SUBSTANCE: invention relates to POST synchronisation, transferred over DSL, i.e. for VoDSL, DSL, receiving data from a packet transmission network, more specifically ETHERNET. A retransmission unit, such as DSLAM, receives Ethernet packets and retransmits information in them over a digital subscriber line.

The synchronising device comprises an extraction unit for selecting at least one stream of received Ethernet packets, and a unit for generating the clock signal, configured as an adaptive synchronisation unit for generating a reference clock signal in accordance with the arrival time of a packet in the selected stream or streams of packets. The reference clock signal can be transmitted to time referencing units in modems. The extraction unit can analyse reception of Ethernet packets so as to find packet streams from a single user transfer target, each packet in the stream carries information in real time, belonging to a service in real time, and then select one or more streams, which should be used by the adaptive synchronisation generator.
