The technical field to which the invention relates

The present invention generally relates to a method for providing packet synchronization in the base station (BS) of a mobile communication system and in particular to a method of providing synchronization forward and reverse packet with respect to time using an additional channel (DC) and additional code channel (DCC) for fast transfer of large amounts of data on the BS, whereas the intermittent mode of transmission (PP).

In particular, the present invention relates to a method of providing packet synchronization, defined in relation to the time of the physical channel and time of the beginning and end of a transmission and to a method for providing Protocol UAA (adaptation level 5 asynchronous transfer mode for high-speed data transmission between base stations through a system of transceiver base stations (PBS) and base station controller (ASC) in the mobile communication system in the conditions of the radio channel, which allow the processing of data with a high transmission rate.

Art
< / is for voice communication, but the standard was developed by the IMT-2000 (international mobile telecommunication - 2000) to facilitate high-speed data transmission. Mobile communication systems (IMT-2000 is capable of transmitting high-quality speech and moving images, as well as to receive information on the Internet.

System for mobile communications mdcr consists of BS containing PBS and KBS, the switching center mobile communications (SMC) and mobile station (MS). The radio link between the MS and the CBE contain a straight line directed from CBE to MS, and return line directed from the MS to the CBE.

All channels are divided into physical channels and logical channels. The logical channel is the physical channel, and perhaps the establishment of many logical channels on the same physical channel. If the physical channel is released, it is automatically exempt logical channels. However, to establish a new logical channel is no need to create a physical channel. If the physical channel can carry a different logical channel, has already been busy for other logical channels, all you need to do is to allocate a new logical channel in the already established physical channel.

Physical channels rate the channels are called so because they are intended for communication between the BS and a particular MS and contain the main channel (OK), a dedicated control channel (CGS) and DK. OK, used compatible with TIA/EIA-95-B (standard of the telecommunications industry Association/electronic industry Association) sends the speech data and alarm signals. To the common channels are channels that are common to base stations and a large number of MILLISECONDS. Direct physical channel transmitted to the MS from the BS, is a channel search call (paging channel), and the reverse channel transmitted by the BS from the MS, is a channel access information intended for the user. These common channels compatible with the standard IS-95-B.

Data transmission in the mobile communication system is characterized by the packet transmission of concentrated data entered in the intervals between long periods without data. Therefore, the mobile communication system of the next generation is designed so that it could operate in the intermittent mode of transmission (PP), in which a dedicated channel is allocated only when there is data to send.

In PP mode data frame is transmitted only when the data to be transmitted exist in the specified period of time in PP mode, the data frame is not transmitted. PP has such obvious advantages as the minimum transmit power, lower noise, which adversely affect the system, and increasing overall system throughput.

PP mode is supported on the SSI and di. In this regard, the SSI can be used as a control channel, which provides the service packet. In PP mode of the SSI passed zero frames for power control and no data is transmitted on the DC. Given the limited radioresource, bandwidth BS and power consumption of the MS, dedicated traffic channels and control channels are connected only during the actual data transmission and are released during the absence of the transfer, when they are in the PP mode. Communication is on a shared channel, and specialty channels are released. As a result, the efficiency radioresource increases. Are the different States of the channels in accordance with the allocation of channels and the presence or absence of information about the state to implement the PP mode.

In Fig. 1 shows a diagram of the transition from one state to another for typical services over a packet transmission is incorporated an active state 11, condition 12 retention management, condition 13 expectations, the idle state 14 state 15 zero package and state 10 initialization. Options services are connected in condition 12 hold control, active state 11 and condition 13 of expectations. Here it should be noted that the present invention relates to a base station that supports PP mode for di and SSI in the active state 11 state 12 retention management.

In Fig. 2 shows a reference model 3G IOS (Specification of interoperability for digital terrestrial interface between SMC and BS and between the BS-mi in the General system for mobile communications.

As shown in Fig. 2, the interface A1 and interface A2/A5 (only for channel data) is defined for signal transmission and for transmission of user information, respectively, between SMC 20 and 32 KBS. Interface A3 is defined for connecting the receiving BS 40 to functional block 34 selection/distribution frames (BSR), the sending BS 30 for soft/softer transfer service between BS-mi. Using the interface A3, signalling data and user data are transmitted between the receiving BS 40 and drilling and blasting 34 sends the BS 30. The A7 interface defined for transmit/receive C the Institute of wired communication between the BS-mi 30 and 40 and between the BS 30 and SMC 20 are in direct communication line, directed from SMC 20 to the BS 30, the reverse link directed from the BS 30 to SMC 20, and a communication line connected between the BS-mi 30 and 40. SMC 20 has a block 22 call control and mobility and the switch 24. SMC 20 is connected to the data network (not shown), such as the Internet, through block 50 with the function of internetworking (FMO).

As shown in Fig.3, the sending BS 30 determines that the MS has formed/finished data transmission/reception to/from another MS or WAPD (3A). Then send BS 30 determines packet traffic required during software maintenance, selects the receiving BS 40, which will contribute a certain packet traffic, and transmits the request message packet (A7 - message sapro 40 checks whether part or all of the requested resources, and sends a reply message packet (A7 - response message about packet) containing information about the resources allocated for packet traffic, the sending BS 30 (3C). Meanwhile, the sending BS 30 waits to receive a response message about packet within the first preset time TFODafter sending a request message packet. After receiving a response message about packet within TFODsending BS 30 prepares a number of selectors frames based on information in the response message packet, and transmits the message about the initiation packet (A7 message about the initiation packet, which specifies the set of resources allocated for real-world usage of the receiving BS 40 (3d). Meanwhile, the receiving BS 40 waits to receive messages about the initiation of a packet within a second predetermined time after transmission of a response message about packet. If the receiving BS 40 receives a message about the initiation of a packet within TPCOSit conveys a message about the connection (A3 - a message about the connection) delaram frames on the sending BS 30 (3rd). Sending BS 30 transmits a confirmation message compounds (A3 - a confirmation message connection) on the receiving BS 40, push the receiving BS 40 that the physical channels for packet traffic ready (3f). Meanwhile, the receiving BS 40 waits to receive a confirmation message connection during the third predetermined period of time TConn.3after the message is transmitted on the connection. If the receiving BS 40 receives a confirmation of the connection within TConn.3she sends a confirmation message initiation packet (A7 - confirmation message initiating a packet) on poison BS 30 (3g). Meanwhile poisonous BS 30 waits to receive a confirmation message initiating a connection during the fourth predetermined time Tp. the INICwhen you send a message initiating a packet when performing 3d. If the sending BS 30 receives a confirmation message initiating a packet within Tp. the INICit transmits the command through the scanned messages to MS, ordering the MS to prepare for packet traffic (3h). Then, the MS transmits a confirmation message level 2 on the sending BS 3 what about the traffic within a specified period of time, or until the sending BS 30 will not extend or complete packet traffic (3j). If the time TFODexpires, the sending BS may select a transmission request message for packet - A7. If the time Tp. the INICexpires, the sending BS may choose to re-transmit this message to complete the preparation for packet traffic or to request the CCM to investigate the Association of the call. If the time Tp. SOSexpires, the receiving BS may refuse to select all radioresource intended for cell cell cell cell) included in this message.

As shown in the table. 6, due to the fact that the field type of the physical channel defines only the channels of IS-95, not the channels mdcr-2000, when the standard mdcr-2000 used in the mobile communication system, the base station cannot identify the channels, as channels mdcr-2000 will be confused with the channels of IS-95.

The set of protocols trafc channel A3 is the set of protocols used for traffic channels assigned to a given selector frame. Its structure is shown in the table. 7.

As can be seen from the table. 7, only the Protocol UAA (adaptation level 2 asynchronous transfer mode PMA), which is used for voice services, in the set of protocols that are used to channel traffic A3. Therefore, this set of protocols is not suitable for data with a high transmission rate.

The above-described known technique has the following problems with the BS and between the BS and not with the line contacts between BS and MS.

The standard IS-95B is not possible to distinguish between OK and DK, and the standard mdcr-2000 does not allow to distinguish OK, SSI and di in the information fields of the selectors of frames shown in the table. 5, and in the procedure shown in Fig.3. Therefore, the BS may not properly identify the channels. In addition, high-speed data transfer cannot be transferred, so as soon as the Protocol OIA, which is used for voice services, in the set of protocols trafc channel A3.

The duration and start time of the packet data cannot be provided by competing bidirectional DC or SKU message packet synchronization, shown in the table. 8. The duration of the PP back to the DC and the SKU is not provided, so it is impossible to make the service fast packet to BS. Sushnosti inventions

Therefore, the present invention is to provide a method that allows PBS to identify the channels through the identification (ID), which allows to identify the primary and secondary channels of the standard IS-95B and the main channel, dedicated control channel and the additional channel (OK, I & C and DK) standard mdcr-2000 in the message transmitted by the BS or received from the BS.

Another objective of the present invention is the provision of the Protocol UAA (adaptation level 5 asynchronous transfer mode, ATM), which is used for efficient data transmission with high speed transfer box set of protocols trafc channel A3.

Another objective of the present invention is the provision of a message packet synchronization, which is defined to support the duration and start time of the packet data on competing bidirectional DC or DCC, as well as to ensure the duration of PP reverse DC and DCC.

Another objective of the present invention is to provide a method for forming messages and synchronization forward and reverse packet in the form of a single message or by forming them on otdelennost units, in order to carry out the operation for packet data transmission in a more accurate time.

These and other problems are solved by the creation of a method of establishing a recreation center that provides batch synchronization for high-speed data transmission in a mobile communication system. In the way of establishing DK transceiver sends the base station determines the packet traffic and transmits to the transceiver receiving the base station, the request message packet containing timing information forward and backward packet, and having the time of use of the channel, which is defined taking into account the mode discontinuous transmission (PP) to maintain the necessary resources when you need to transfer large amount of data with a high transmission rate. Then the transceiver receiving the base station transmits to the transceiver sends the base station a response message about packet containing information regarding the resources allocated for packet traffic.
