Consult Fig. 3, another embodiment of the method for trunking communication provided by the invention comprises:

201, terminal is set up default bearer.

Terminal is set up one to particular access point title (APN, Access Point Name) packet data network (PDN, Packet Data Network) connects, this APN is the specific APN of trunking communication institute, in this process, default bearer (Default Bearer) is set up, and may also set up an independent dedicated bearer (Dedicated Bearer) for terminal in step 201 back system simultaneously;

202, the mobile management entity triggering terminal adds the trunking communication group of described terminal unit contractual.

MME is according to local subscribed services (HSS, Home Subscriber Server) subscription data of the terminal that transmits is determined which trunking communication group of terminal unit contractual, trigger voluntarily then and add these trunking communication groups, be that MME sends adding trunking communication group of instructions (TGJC to S-GW, Trunk Group Join Command) message, described TGJC message is carried the trunking communication group identification of described trunking communication group, and as IP multicast address, SGW sends TGJC message to PGW then.

203, group's insertion authority.

PGW sends TGJC message to cluster server after receiving the terminal adding TGJC message of SGW transmission; PGW and cluster server carry out group's insertion authority of terminal, PGW provides the sign of terminal to cluster server, as international mobile subscriber identity (IMSI, International Mobile Subscriber Identification Number) and portable terminal integrated services digital network (MSISDN, Mobile Subscriber International ISDN/PSTN number) sign; Cluster server is according to user's sign and the user contracting data on the cluster server thereof, perhaps, the sign of the terminal that cluster server provides according to PGW is got user's subscription data from HSS/HLR, or store the subscription data that cluster service is arranged on the cluster server, determine whether allowing this terminal to use cluster service; After cluster server is by the authentication of terminal and mandate, terminal adds the trunking communication group of described trunking communication group identification, the terminal that adds trunking communication group can be called colony terminal, just set up shared transmission channel between cluster server and the PGW; Same reason, if set up shared transmission channel between cluster server and the PGW before this, the shared transmission channel before then reusing and do not need to rebulid.

204, PGW sends the first trunking communication group bearing activation request message to SGW, and SGW sends the second trunking communication group bearing activation request message to MME.

The described first and second trunking communication group bearing activation request messages carry the APN of described trunking communication group identification and appointment;

205, MME sends the 3rd trunking communication group bearing activation request message by the base station to terminal.MME judges according to the APN of described trunking communication group identification and appointment whether the base station has set up the first downlink tunnel port-mark and IP address before sending the 3rd trunking communication group bearing activation request message; If set up the first downlink tunnel port-mark and IP address, when sending the 3rd trunking communication group bearing activation request message, send the indication base station simultaneously and use the first downlink tunnel port-mark set up and the indication information of IP address; If do not set up the first downlink tunnel port-mark and IP address, when sending the 3rd trunking communication group bearing activation request message, send simultaneously and set up group's RAB request to the base station, make the base station set up the first downlink tunnel port-mark and IP address; The first downlink tunnel port-mark and IP address refer to descending GTP-U (the GTP user plane of the S1-U interface of base station assigns, GTP, GPRS Tunnelling Protocol, general grouped wireless protocol tunnel agreement) TEID (Tunnel End Point Identifier, tunnel port-mark) and IP address thereof.

Whether the base station no matter MME judges sets up the first downlink tunnel port-mark and IP address, the base station sends to terminal with the 3rd trunking communication group bearing activation request message, and distribute a shared transmission channel of eating dishes without rice or wine to give terminal simultaneously, thereby set up the shared transmission channel from the base station to the terminal.Be similar to the shared transmission channel between SGW and the base station, all terminals in the same residential quarter under the base station also are the common shared transmission channel of eating dishes without rice or wine of using therewith between the base station.

206, MME receives group's RAB response message that the base station sends.

If the base station is when receiving the 3rd trunking communication group bearing activation request message in the step 205, also received the group's RAB request of setting up that MME sends, then the base station assigns first downlink tunnel port-mark and IP address, and send group's RAB response message to MME, carry the first downlink tunnel port-mark and the IP address of foundation in the described group RAB response message;

If the base station when receiving the 3rd trunking communication group bearing activation request message, receives the first downlink tunnel port-mark that use set up and the indication information of IP address, then reply the response message that uses the parameter of having set up and give MME.

207, the first trunking communication group bearing activation response message of MME receiving terminal transmission.
