BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. In this embodiment, a cluster communication processing method is provided. FIG. 1 is a flowchart 1 of a cluster communication processing method according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps: Step S102: Obtain system information. The system information carries the TPCH parameter information of the cluster paging channel TPCH capable of monitoring the cluster paging message; Step S104, receiving the cluster paging message according to the TPCH parameter information; Step S106, searching according to the received cluster Call the message for cluster communication. Through the above steps, the receiving of the cluster paging message is controlled by the newly added dedicated channel, so that the user can quickly access the cluster system for communication, and the effect of the concurrent communication with the original system is better. In order to prevent the UE from performing repeated processing on the same paging message on the TPCH, in the case that the cluster call message is identified by the sequence number, the following processing may be performed according to the received cluster paging message: determining the received cluster call message Whether the serial number is the same as the serial number of the previously processed cluster paging message; if the judgment result is yes, the received paging message is discarded, no processing is performed, and if the determination result is negative, , performing cluster communication according to the received cluster paging message. When the cluster communication is performed according to the received cluster paging message, the service identification information for receiving the cluster control plane data and the cluster service data may be obtained from the cluster paging message. For example, the service identifier information may be a temporary The Trunking Radio Network Temporary Identifier (TRNTI) is used to receive the cluster control plane data and the cluster service data according to the obtained service identifier information. The service identifier information may be used to identify the channel information for transmitting the service, and the UE may further parse the received service based on the service identifier information. When receiving the cluster control plane data and the cluster service data according to the service identifier information, the following processing may be adopted: First, the cluster group control channel TGCCH for transmitting the cluster control plane data is determined according to the service identifier information; and the cluster control is received according to the determined TGCCH. The data of the cluster group service channel TGTCH for transmitting the cluster service data is determined according to the received cluster control plane data; the cluster service data is received according to the determined TGTCH, wherein the TGCCH and the TGTCH are all newly added channels in the LTE system. The new channel not only achieves the rate of the user accessing the cluster group, but also has good isolation from other services of the LTE system, so that the cluster communication in the LTE system is concurrent with other common services and does not affect each other. Similarly, in order to not repeat the same cluster control plane data on the TGCCH, the cluster control plane data may be identified by the serial number. Only when the data of the cluster control plane changes, the serial number changes, so Determining whether the sequence number of the received cluster control plane data is the same as the sequence number of the previously processed cluster control plane data; if the judgment result is the same, the received cluster control plane data may be directly discarded, and the judgment result is If the value is NO, the cluster control plane data is not processed and is the new cluster control plane data. Therefore, the TGTCH is determined based on the received cluster control plane data. Preferably, the foregoing embodiments and preferred embodiments are applied to a Long Term Evolution (LTE) system, and coexist with LTE services by applying different channel resources without affecting each other. It should be noted that when different channel resources and LTE services coexist without affecting each other, different services correspond to different channel resources, and different scenarios may be applied according to different service sequences. The corresponding processing can also be different. Certainly, when the same processing exists in both of them, the same resource can also be shared. For example, when there is an RRC link between the UE and the network side, the two can mutually use the link to send corresponding information, and the processing is performed. Not only save resources, but also high efficiency. In the embodiment, a cluster communication processing method is also provided. FIG. 2 is a flowchart 2 of a cluster communication processing method according to an embodiment of the present invention. As shown in FIG. 2, the process includes the following steps: Step S202, sending a system Information, where the system information carries TPCH parameter information of the cluster paging channel TPCH that the terminal can monitor the cluster paging message; Step S204, sending a cluster paging message on the TPCH, where the terminal is based on the TPCH parameter information Receiving a cluster paging message, and performing cluster communication according to the received cluster paging message. Preferably, in order not to repeatedly process the same cluster paging message on the TPCH, before sending the cluster paging message on the TPCH, a sequence number for identifying the cluster paging message may also be added to the cluster paging message. In order to realize the efficiency of the cluster communication and the common service of the system, after the cluster paging message is sent on the TPCH, the cluster service can be processed through the newly added channel, for example, it can be used for the transmission cluster control. The cluster control channel data is transmitted on the cluster group control channel TGCCH of the polygon data; the cluster service data is transmitted on the cluster group traffic channel TGTCH for transmitting the cluster service data. Similarly, in order to not process the same cluster control plane data on the TGCCH, a sequence for identifying the cluster control plane data may be added to the cluster control plane data before the cluster control plane data is transmitted on the TGCCH for transmitting the cluster control plane data. number.

In order to meet the requirements of the cluster and not affect the common LTE service, a new access method is provided in this embodiment to satisfy the LTE cluster listening user access. That is, in the embodiment, a cluster communication processing method is provided, by which the cluster user access is implemented on the basis of the LTE standard, so that the cluster listening user can quickly access the cluster system, and the cluster says the user and the user There is an RRC link on the network side. The cluster listens to the user and the network side does not have an RRC link. If the terminal needs to perform LTE common services during the cluster service, it must provide a method to support the concurrency of the service. Therefore, in this method, The new logical channel is adopted to support the concurrency of the cluster service and the LTE service, so that the two do not affect each other. The present embodiment will be described below. It should be noted that three logical channels (Lgch) are added in the method, including a trunking paging channel (Trunking Paging Channel, TPCH for short): for cluster paging; trunk group control channel (Trunking Group Control Channel) , referred to as TGCCH): Used to transmit downlink cluster control signaling; Trunking Group Traffic Channel (TGTCH): used to transmit downlink cluster public service data. The TPCH resource parameters specific to the LTE cluster system are carried in the System Information Block (SIB). The SIB is newly configured for adding a cluster communication service in the LTE system. SIB, the TPCH configuration information is added to the SIB, including: TPCH period (tpchCycle), indicating the paging listening period of the cluster user; T-nB indirectly indicating the transmission time (frequency) of the TPCH channel. After the UE camps on the cell, the SIB of the LTE cluster system is read, and the physical layer is configured according to the TPCH resource parameter in the SIB of the LTE cluster system. After the physical layer is configured according to the TPCH resource parameter, the cluster paging can be detected. The content of the cluster paging includes the group information and the TRNTI. The UE can determine whether the UE accesses the group according to the group information. According to the TRNTI, the physical layer of the UE can detect whether the physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) is detected. There is corresponding scheduling information, and if so, the corresponding information is detected and sent to the upper layer on the Physical Downlink Shared Channel (PDSCH). The upper media access control (Media Access Control, abbreviated as MAC) is sent to the RRC by analyzing the logical channel and determining the data on the TGCCH. The RRC configures the TGTCH to listen to the user traffic channel through the message delivered on the TGCCH. TGCCH and TGTCH are distinguished by different Lgch IDs. By analyzing the logical channel, the MAC can distinguish whether it is control signaling on the TGCCH or service data on the TGTCH. The paging is periodically broadcast on the TPCH. The cells in the paging message include a group ID indicating which group initiated the paging; TRNTI is used for the physical layer to perform descrambling; in order to make the UE not process the TPCH The paging message is added to the paging message, and the paging sequence number of each group call is different. After the UE receives the paging, if the serial number is the same as the last processed paging sequence number, the paging number is not performed. Processing, different processing corresponding pages; receiving paging and paging processing takes the following steps:

Sl, the group of the newly added user of the cluster periodically checks the Paging Radio Network Temporary Identifier (Position Paging Radio Network Temporary Identifier) on the PO subframe of the Paging Frame (PF) configured for the broadcast message. PDCCH of TP-RNTI); TP-RNTI is a newly defined radio network temporary identifier RNTI identifier for cluster paging.

S2, if there is TPCH indication information on the channel, the cluster called user will decode the TB on the PDSCH; S3, if the TB on the PDSCH is successfully decoded, the baseband will transmit the correctly decoded MAC PDU to the upper layer;

S4: For decoding the cluster paging RRC message on the TPCH, if the UE belongs to the group, start receiving the downlink control plane data related to the group by using the TRNTI in the paging message. The downlink cluster control signaling is periodically broadcasted in the TGCCH channel, and the downlink cluster control signaling includes related resource information of the transport service data channel TGTCH, including a data radio bearer (Data Radio Bearer, Jane) Information called DRB), Packet Data Convergence Protocol (PDCP) information corresponding to DRB, Radio Link Control (RLC) information, MAC resources and physical layer (PHY) related resources information. Because the cluster system is a plurality of listening users, the data on the TGCCH is periodically broadcasted. The sequence number is added to the cluster control signaling message on the TGCCH. Only when the related resource parameters in the control signaling change, the serial number is Will change. The cluster terminal processes a cluster control signaling. If a cluster control signaling is received later and the sequence number is the same as the sequence number of the previous processing, the packet is reconfigured according to the parameters in the new cluster control signaling. PDCP, RLC, MAC, PHY. The embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 12 is a mapping diagram of a logical channel and a transport channel according to an embodiment of the present invention. As shown in FIG. 12, in the LTE system, a new link 5|$ (channel, TPCH) is added to the mapping relationship between the logical channel and the transport channel. , TGCCH and TGTCH, the three logical channels are mapped to the downlink shared channel (downlink shared channel, abbreviated as DL-SCH) transport channel 13 is used to listen to the cluster according to an embodiment of the present _invention: following the procedure called whistling The schematic diagram, as shown in Figure 13, includes the following processing:

After the UE is powered on and camped on a cell, the system information of the cell, the terminal configures the physical layer according to the TPCH resource information in the cluster cell system information, and the object layer decodes the cluster paging according to the TPCH paging channel parameter. The physical layer receives the cluster on the TPCH and sends it back to the RRC. The RRC determines whether the UE belongs to the group of the cluster paging, and if so, configures the TRNTI in the cluster to the physical layer. The physical layer resolves the control signaling on the TGCCH through the TRNTI. If || ^: receives the paging on the TPCH channel, it will judge whether the serial number in the paging message is the same as the serial number in the previously processed paging message, and if it is the same, it is discarded. The physical layer is resolved to TRNTI

FIG. 14 is a schematic diagram of a clustering user access flow according to an embodiment of the present invention. As shown in Figure 14, the process includes the following processing:

The UE idle state initiates a cluster group call, and the UE initiates an RRC link. After the RRC link is successfully established, the CRNTI is obtained. The network side configures the resource information of the cluster by the reconfiguration message. After the reconfiguration succeeds, the UE analyzes the signaling and service data of the cluster according to the CRNTI and the configured resource information, and enters the cluster to say the user. The access implementation methods of several concurrent scenarios in the embodiments of the present invention are described below with reference to the accompanying drawings: FIG. 15 is a schematic diagram of a process in which a terminal has established a cluster service, enters a listening user, and subsequently accesses an LTE service according to an embodiment of the present invention. As shown in FIG. 15, the UE is in a cluster listening user, initiates an LTE service, and performs RRC chain building. After the RRC is successfully established, the CRNTI is obtained. The network side configures resource information of the LTE service by reconfiguring the message. After the reconfiguration succeeds, the UE parses the cluster to listen to the user signaling and the service plane data according to the TRNTI, and parses the LTE service signaling and service data according to the CRNTI, and enters the cluster listening user and the LTE service concurrent state. That is, the cluster service analyzes the cluster signaling and the service data through the T-RNTI. After the LTE is established, the LTE obtains the CRNTI, and the LTE service signaling and the service data are analyzed by the CRNTI. The LTE service and the cluster service are mutually synchronized and implemented by different RNTIs. Does not affect. FIG. 16 is a schematic diagram of a process in which a terminal has established a cluster service, enters a user, and subsequently accesses an LTE service according to an embodiment of the present invention. As shown in FIG. 16, the UE has established a cluster service, and is in a user state, and has an RRC link. And the data is parsed by CRNTI. Subsequent receipt of LTE service paging, initiated chain building. Because there is already an RRC link, the UE does not need to re-establish the RRC link. The UE directly sends the link request to the network through the tconcurrentLTERequest message on the DCCH. After the network receives the packet, it directly delivers the resource information required by the LTE service, and configures different DRB and Lgch resources. Information to distinguish between LTE services and clusters that say users. FIG. 17 is a schematic diagram of a process in which a terminal has established a normal LTE service and a subsequent access cluster listens to a user according to an embodiment of the present invention. As shown in FIG. 17, the UE is in an LTE service state, and subsequently receives a cluster group call page, and the UE After the group call paging of the cell is configured, the TRNTI in the paging message is configured, and the TRNTI parses the data. After receiving the group resource configuration message, the user resource information is configured according to the message content. The UE parses the LTE signaling and the service data through the CRNTI, and resolves the cluster signaling and the service data by using the TRNTI. The UE is in a state in which the common LTE service and the cluster listen to the user concurrently. That is, the LTE acquires the CRNTI after the RRC is established, and the LTE service signaling and the service data are analyzed by the CRNTI. The cluster listening user service analyzes the signaling and the service data through the T-RNTI, and the LTE service and the cluster service are mutually concurrently implemented by different RNTIs. Do not affect each other. FIG. 18 is a schematic diagram of a process in which a terminal has established a normal LTE service and a subsequent access cluster is said to be a user according to an embodiment of the present invention. As shown in FIG. 18, the terminal has established a normal LTE service. After the normal LTE service is established, the UE is already in the LTE service. Status, there is already an RRC link and the signaling and service data are resolved by CRNTI. After the RRC link is initiated, the RRC link does not need to re-establish the RRC link. The common cluster connection request is sent to the original RRC link. The tconcurrentTrunkingRequest message is sent to the network side on the DCCH, and the subsequent network side is re-allocated. The message is configured with the resource information required by the cluster service. The DRB and the logical channel information of the cluster service and the normal LTE service are distinguished by different values, that is, the LTE service and the cluster said user are distinguished by configuring different DRB and Lgch resource information.
