Method for adaptive routing in multidimensional messaging route communication network / 2431945

Quality control (QC) of communication channels (CC) coming into a communication node (CN) is performed in each CN. CC QC results are sent to all CN of the communication network. CC transmission speed (TS) is estimated depending on the CC quality. TS of one-dimensional routes (OR) is the determined depending on CC TS coming into OR according to CN routing tables. Further, a messaging multidimensional route (MR) is formed, through which all multi-packet messages are transmitted, wherein at the beginning, the MR includes the OR with the highest TS, and then OR with the next lower TS and so on, until the MR TS ensures timely transmission of the entire message of given length with the required probability, and the message is then sent on the MR. Quality and CC TS are determined from packet transmission results based on primary and secondary characteristics of CC quality. OR TS is calculated for independent series-connected CC which form OR in a point-point connection from a CN which is the source and to a CN which is the recipient of the message, the total number of which is limited by the maximum allowable time for delivering the message. Initial formation of OR for carrying the message from the CN which is the source of the message to the CN which is the recipient of the message is carried out on the Bellman-Ford routing protocol.

DISCLOSURE of SPOSOBNOSTEY INVENTIONS

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention will be more fully understood from the detailed description presented herein below accompanying drawings, which are given for illustration only and thus do not limit the present invention. The following description includes details in order to ensure full understanding of the present invention. However, specialists in the art it will be obvious that the present invention may be practiced without these details. For example, in the following description, specific terms are used, but the present invention is not limited to these terms.

In some cases, known structures and devices are omitted in order to avoid ambiguities of the concept of the present invention or the basic functions of structures and devices are shown in block diagram and/or flowchart. The same reference numbers will be used throughout the drawings to refer to same or similar parts.

Figure 1 is a drawing for illustrating transmission schemes in compressed mode.

Figure 1 shows a schematic structure of a frame in accordance with the scheme of transfer in compressed mode. In accordance with the scheme of transfer in compressed mode, any single frame or two is nepreryvnyh frame are used as the compressed frame, including gap compressed mode (CF) in the frame or between two continuous frames. In other words, some of the slots of the frame, which is defined to be used as a compressed frame, so that the slots included in the CF period, are not used in data transmission. These slots are used to carry out the operation of the interruption of transmission/reception data in the CF period and search the neighboring cell and the neighboring network.

In order to reduce the effect of reducing the coefficient of expansion of the spectrum of the signal due to the existence of the CF period and to maintain the quality of communication, data can be transferred in a state of increased transmit power in relation to some of the slots of the compressed frame. As shown in figure 1, the slots for data transmission with the increased transmit power are preferably before the beginning of the CF period and after CF period ends. The value of power, increased in some slots compressed frame may be determined in accordance with the reduction in transmission time. Examples of factors to measure the quality of communication may include the ratio of erroneous bits (bit error rate - BER) and frame error rate frame error rate FER).

The network can be determined which frame is used as the compressed frame. The compressed frame is periodically generated in the compressed mode, and can be generated on request the su, if you want to. The speed and type of compressed frame can be determined by the requirements of the different media channels and measurements.

Further, the scheme of discontinuous transmission (DTX) in the uplink direction will be described as another method of power control. In the communication system in order to reduce the power consumption of the battery of the user equipment and to increase the capacity of the channel in the uplink direction, the operation of discontinuous transmission developed in the transmission in the uplink direction. That is, a user equipment discontinuously transmits data. In view of the user equipment, used method for different power control in accordance with the interval in which data is transmitted, and an interval in which no data is transmitted, that is, DTX-interval.

For example, if DTX interval is used, data is not always transmitted. Accordingly, when data is transmitted, the user equipment is in a condition or state of "on" and when no data is transmitted, the user equipment is in the condition of minimization of energy consumption, such as the sleep state or the Off state.

If the scheme of discontinuous transmission in the uplink direction and the transmission scheme in compressed mode are operating simultaneously, the exact preferably checked the user equipment. Next, the operation of the user equipment in accordance with the variants of implementation of the present invention, when the transmission scheme in compressed mode in the uplink direction and the scheme of discontinuous transmission in the uplink direction are simultaneously applied, will be described in detail.

First, the operation of the user equipment associated with a discontinuous transmission enhanced dedicated channel (E-DCH) in accordance with the embodiment of the present invention, will be described.

Figure 2 is a drawing to illustrate the operation of a discontinuous transmission E-DCH.

Referring to Figure 2, the channel E-DCH is a channel for transmitting packet data in the uplink direction and displayed in the physical channel, such as an enhanced dedicated physical data channel (E-DPDCH) and an enhanced physical control channel (E-DPCCH). Channel E-DPDCH physical channel used to transmit E-DCH data, and channel E-DPCCH is a physical channel used to transmit the management information associated with the E-DCH. In General, channel E-DPDCH and channel E-DPCCH are transmitted simultaneously.

When E-DCH is transmitted via the E-DPDCH and E-DPCCH in order to allow the receiving side, for example, the base station (node-B), it is easy to implement E-DCH demodulation using detection of E-DCH or estimation of the channel parameters, the dedicated physical control channel (DPCCH) is also passed. In more detail, the management information generated at the first level, is transmitted through the DPCCH. For example, can be transmitted, at least one of: information feedback information FBI), the command control transmit power (transmit power control - TRS) and indicator combination transport format transport format combination indicator (TFCI), including the upward pilot signal to support the estimation of channel parameters.

Meanwhile, the management information, which is not transmitted through DPCCH, that is, the management information, which is typical in the E-DCH may be sent via E-DPCCH as the management information used in the E-DCH demodulation. For example, TFCI, HARQ information, and information of the scheduling request may be submitted via E-DPCCH. At this time, E-DPDCH, E-DPCCH and DPCCH may be transmitted simultaneously and multiplexed using different codes or different orthogonal phase components.

As shown in figure 2, the user equipment starts DPCCH transmission before transmitting the E-DPDCH and E-DPCCH. In other words, E-DPDCH and E-DPCCH transmission begins at a specified time after DPCCH transmission begins, or after a predefined number of slots transmitted. DPCCH signal, which is transmitted before the E-DPDCH and E-DPCCH transmitted, called the DPCCH preamble.

Figure 3 shows the case where two slots are used as the DPCCH preamble. D is more, the number of slots used as a DPCCH preamble is denoted as N.

The user equipment transmits DPCCH at a specified time after the transmission of the E-DPDCH and E-DPCCH is finished, or after a predefined number of slots transmitted, and then finishes the process of transmission of E-DCH. DPCCH signal, which is transmitted after the transmission of the E-DPDCH and E-DPCCH is finished, is called the DPCCH postamble. Figure 2 shows the case where one slot is used as the DPCCH postamble. Further, the number of slots used as the DPCCH postamble, denoted as M

As described above, the DPCCH DPCCH preamble and postamble, respectively, are transmitted before and after the E-DPDCH and E-DPCCH transmitted so that the reception side, for example, a base station (node-B), detects E-DCH with greater probability of success.

In the DPCCH preamble, the number of slots used as a DPCCH preamble may be determined in accordance with the communication status of the user equipment. For example, if the user does not transmit data during a time longer than the specified interval prior to transmitting the E-DCH, then more slots can be used as a DPCCH preamble, compared with the case where the user does not transmit data for a specified interval or less.

If the user does not transmit data during a given interval, or the smaller the interval is, the number N1 of slots used as a DPCCH preamble, can be equal to 2. In contrast, if the user does not transmit data during a time longer than the specified interval, the number N2 of slots used as a DPCCH preamble, may be equal to 15. This is because if no data is transmitted for a longer time, it is preferable that the management information required for synchronization in the uplink direction, shall be transferred to and more control information required for the implementation of power control is to be transferred.

As shown in figure 2, in the transmission of DPCCH, as described above, the DPCCH preamble is transmitted a predetermined number N of slots, for example, two slots before transmitting the E-DPDCH and E-DPCCH and DPCCH postamble is transmitted a predetermined number M of slots, for example, one slot after the transmission of the E-DPDCH and E-DPCCH. The process of transmission of DPCCH preamble, transmitting the E-DPDCH and E-DPCCH and DPCCH transmission postamble is considered as one transmission unit. One transmission unit, depicted on the left side of figure 2, is called the first transmission unit and a transmission unit shown on the right side of Figure 2 is called the second transmission unit. In this case, the predefined DTX-interval can be set between the first transfer unit and second transfer unit. No data is transmitted in DTX-interval. If the DTX interval is completed, the DPCCH preamble is transmitted again, E-DCH, that is, E-DPDCH and E-DPCCH is transmitted, and the DPCCH postamble is transmitted, thus completing the data transfer of one transfer unit.

Now will be described a method of transmitting E-DCH user equipment, when the circuit intermittent transmission and the transmission scheme in compressed mode E-DCH simultaneously applied.

Figure 3 is a drawing to illustrate the operation of the user equipment in accordance with the embodiment of the present invention, when the transmission scheme in compressed mode and the scheme of discontinuous transmission simultaneously applied in the transmission of E-DCH.

As described above, for the transmission of E-DCH, E-DPDCH and E-DPCCH is transmitted, and DPCCH is transmitted together with the E-DPDCH and E-DPCCH. DTX-interval in accordance with the scheme of discontinuous transmission exists between the first transmission unit, which is transmitted first and the second transmission unit, which is transmitted to the next. That is, transmission data corresponding to the first block transmission is completed and, after DTX interval, the transmission data corresponding to the second transmission unit, starts the transmission of DPCCH preamble.

At this time, as shown in Figure 3, if part of the DPCCH preamble of the second transmission unit is determined to be transmitted in the CF period in accordance with the scheme of transfer in compressed mode, DPCCH premable not transmitted in part or in all slots, blocking the affected CF period, but E-DPDCH and E-DPCCH and DPCCH and the remaining preamble, the DPCCH signal and the DPCCH postamble is transmitted, in accordance with the embodiment of the present invention. If the DPCCH postamble is determined to be transmitted in the CF period in accordance with the scheme of transfer in compressed mode, the DPCCH postamble is not transmitted in part or all of the slots that overlap the CF interval, but the E-DPDCH and E-DPCCH and DPCCH preamble, the DPCCH signal and the remaining DPCCH postamble is transmitted.

This is because the checksum for error checking (error check sum - ECS) can be used in the E-DCH data, the HARQ operation is performed, and the deterioration of the reception due to the lack of DPCCH DPCCH preamble and postamble at the receiving side can easily be restored, though at least one of the mentioned DPCCH DPCCH preamble and postamble determined to be transmitted in the above-mentioned CF period and cannot be transferred.

If the user equipment does not transmit data during a time longer than a specified time interval, as shown in Figure 4, the number N2 of slots, polzuuschihsa as DPCCH preamble, can be set to 15. This is because, as described, if no data is transmitted for a longer time, it is preferable that the management information required for synchronization in the line up, should be transferred to, and more control information required for controlling the power must be transmitted.

In the present embodiment, like the version of the implementation in figure 3, if part of the long DPCCH preamble is determined to be transferred to the CF period in accordance with the scheme of transfer in compressed mode, long DPCCH preamble is not transmitted in part in all the slots that overlap the CF period, but the E-DPDCH and E-DPCCH and DPCCH and the remaining preamble, the DPCCH signal and the remaining DPCCH postamble is transmitted, in accordance with the embodiment of the present invention.

Similarly, if the DPCCH postamble is determined to be transmitted in the CF period in accordance with the scheme of transfer in compressed mode, the DPCCH postamble is not transmitted in part or all of the slots that overlap the CF period, but the E-DPDCH and E-DPCCH and DPCCH preamble, the DPCCH signal and the remaining DPCCH postamble is transmitted.

5 is a drawing to illustrate the operation of the user equipment in accordance with another embodiment of the present invention, when the transmission scheme in a compressed re is the ima and the scheme of discontinuous transmission simultaneously applied in the transmission of E-DCH.

In the present embodiment, unlike the embodiments shown in figure 3 and 4, if part of the long DPCCH preamble is determined to be transferred to the CF period in accordance with the scheme of transfer in compressed mode, the DPCCH and the remaining channel signals of the entire transmission unit associated with said long DPCCH preamble and the slots that overlap the CF period, are not transmitted in accordance with the embodiment of the present invention. That is, all remaining DPCCH preamble, the DPCCH signal, the DPCCH postamble, E-DPDCH and E-DPCCH is not transmitted.

Similarly, if the DPCCH postamble is defined to be transferred to the CF period in accordance with the scheme of transfer in compressed mode, the DPCCH and the remaining channel signals of the entire transmission unit associated with the DPCCH preamble and the slots that overlap the CF period, are not transmitted in accordance with the embodiment of the present invention. That is, all remaining DPCCH preamble, the DPCCH signal, the DPCCH postamble, E-DPDCH and E-DPCCH is not transmitted.

The management information for synchronization in the uplink direction and control information required to control the power transmitted through the long DPCCH preamble transmitted after the data has not been transmitted within a specified time interval. Accordingly, if the long DPCCH preamble is e is taken normally, it is difficult to establish synchronization in the uplink direction. In this case, a fatal error may occur in transmitting/receiving data.

Next, the operation of the user equipment associated with a discontinuous transmission high-speed dedicated physical control channel (HS-DPCCH), will be described as one of the embodiments of the present invention.

6 is a drawing to illustrate the functioning of the discontinuous transmission of HS-DPCCH.

Channel HS-DPCCH signal is sent to the feedback in the uplink direction, associated with the transfer of high-speed downstream shared channel (high speed-downlink shared channel (HS-DSCH)Signal feedback associated with HS-DSCH, includes HARQ acknowledgement (ACK/NACK) and an indication of the quality of the channel.

When HS-DPCCH is transmitted like the E-DCH in order to allow the receiving side, for example, the base station (node-B), it is easy to implement E-DCH demodulation using E-DCH detection or estimation of the channel DPCCH is also passed. That is, the management information for managing capacity and the necessary management information, including the pilot signal to perform the estimation of the channel parameters may be passed through the DPCCH. At this time, the HS-DPCCH and DPCCH can be simultaneously transmitted and multiplexed using different codes or different orthogonal phase comp the components.

As shown in Fig.6, the user equipment starts the transmission of DPCCH before transmission of HS-DPCCH. That is, the transmission of HS-DPCCH begins at a specified time after transmit DPCCH or a predefined number of slots transmitted. DPCCH signal, which is transmitted before the HS-DPCCH is transmitted, called the DPCCH preamble. 6 shows the case when two slots are used as the DPCCH preamble. Further, the number of slots used as a DPCCH preamble, denoted as N.

The user equipment transmits DPCCH at a specified time after the transmission of HS-DPCCH is completed or after a predefined number of slots transmitted, and then finishes the process of transmission of HS-DPCCH. DPCCH signal, which is transmitted after the transmission of HS-DPCCH is finished, is called the DPCCH postamble. 6 shows a case where one slot is used as the DPCCH postamble. Further, the number of slots used in the DPCCH postamble, denoted as M

As described above, the DPCCH DPCCH preamble and postamble, respectively, are transmitted before and after the HS-DPCCH transmitted so that the reception side, for example, a base station (node-B), detects the HS-DPCCH with a higher probability of success,

As shown in Fig.6, in the transmission of DPCCH, as described above, the DPCCH preamble is transmitted a predetermined number N of slots, for example, two slots before transmitting the HS-DPCCH and DPCCH postembolization number M of slots, for example, one slot after the HS-DPCCH transmission.

The process of transmission of DPCCH preamble, the transmission of HS-DPCCH and DPCCH transmission is counted as one transmission unit. One transmission unit, shown on the left side of Fig.6, refers to the first transmission unit and one transmission unit, shown on the right side 6, belongs to the second transmission unit.

In this case, the predefined DTX-interval can be set between the first transfer unit and second transfer unit, and data is not transferred to the DTX-interval. If DTX interval is over, the DPCCH preamble is transmitted again, DPCCH and HS-DPCCH are transmitted and DPCCH postamble is transmitted, in conclusion, thus, data of one transmission unit.

At this time, compared with the scheme of discontinuous transmission E-DCH, while the E-DPDCH and E-DPCCH are transmitted from the slot directly next to the two slots, in which the DPCCH preamble is transmitted in a discontinuous transfer scheme E-DCH is transmitted on the HS-DPCCH from the middle part of the slot directly next to the slot in which the DPCCH preamble transmitted in a discontinuous transfer scheme for the HS-DPCCH as shown in Fig.6.

Even in the transmission of the DPCCH postamble, while the E-DPDCH and E-DPCCH are transmitted to slot directly in front of the slot in which the DPCCH postamble is transmitted in a discontinuous transfer scheme E-DCH, HS-DPCCH is transmitted to the middle part of the slot directly in front of the slot in which the DPCCH postamble is transmitted, in prerun the th scheme to transmit HS-DPCCH, as shown in Fig.6.

Now will be described the method for transmission of HS-DPCCH user equipment, when the circuit intermittent transmission and the transmission scheme in compressed mode HS-DPCCH simultaneously applied.

7 is a drawing to illustrate the operation of the user equipment in accordance with another embodiment of the present invention, when the transmission scheme in compressed mode and the scheme of discontinuous transmission simultaneously applied in the transmission of HS-DPCCH.

As described above, for transmission of HS-DPCCH, HS-DPCCH is transmitted and DPCCH is transmitted together with the HS-DPCCH. DTX-interval in accordance with the scheme of discontinuous transmission exists between the first transmission unit, which is transmitted first and the second transmission unit, which is transmitted next.

That is, transmission data corresponding to the first block transmission is completed and, after DTX interval, the transmission data corresponding to the second transmission unit, starts the transmission of DPCCH preamble.

At this time, if a portion of the DPCCH preamble of the second transmission unit is determined to be transferred to the CF period in accordance with the scheme of transfer in compressed mode, the DPCCH preamble is not transmitted in part or all of the slots that overlap the CF period, but the HS-DPCCH and DPCCH and the remaining preamble, the DPCCH signal and the DPCCH postamble is transmitted, in accordance with the present embodiment is about inventions.

If the DPCCH postamble is defined to be transferred to the CF period in accordance with the scheme of transfer in compressed mode, the DPCCH postamble is not transmitted in part or all of the slots that overlap the CF period, but the HS-DPCCH and DPCCH preamble, the DPCCH signal and the remaining DPCCH postamble is transmitted.

Fig is a drawing to illustrate the operation of the user equipment in accordance with another embodiment of the present invention, when the transmission scheme in compressed mode and the scheme of discontinuous transmission simultaneously applied to HS-DPCCH transmission.

In the present embodiment, unlike the implementation shown in Fig.7, if part of the DPCCH preamble is determined to be transferred to the CF period in accordance with the scheme of transfer in compressed mode, the DPCCH and the remaining channel signals of the entire transmission unit associated with the DPCCH preamble and the slots that overlap the CF period, are not transmitted in accordance with the embodiment of the present invention.

Similarly, if the DPCCH postamble is defined to be transferred to the CF period in accordance with the scheme of transfer in compressed mode, the DPCCH and the remaining channel signals of the entire transmission unit associated with the DPCCH preamble and the slots that overlap the CF period, are not transmitted in accordance with the choice made is tvline of the present invention. That is all from: DPCCH preamble, DPPCCH signal, the remaining DPCCH postamble, and HS-DPCCH is not transmitted.

This is due to the fact that ECS for error checking cannot be applied to the HS-DPCCH data and HARQ operation cannot be performed. Accordingly, if at least one of the DPCCH DPCCH preamble and postamble is passed to the CF period and thus cannot be transmitted, then the probability of deterioration of the reception due to the lack of DPCCH DPCCH preamble and postamble at the receiving side is high.

Specialists in the art it will be obvious that various modifications and variations can be made in this invention without deviating from the essence or scope of the invention. Thus, it is understood that the present invention covers the modifications and variations of this invention provided that they fall under the scope of the attached claims and are equivalent. Although the examples that are used when the E-DPDCH/E-DPCCH and HS-DPCCH are transmitted together with the DPCCH discussed in the above-described embodiments, implementation, specialists in the art it will be obvious that the method is equivalent or similar to the transmission method described in the present description, can be used in relation to various other channel signals.
