It should be noted that step S501 to step S521 is group's activation process, if group is in active state, can omit This flow if group is in silent status, firstly the need of this flow is performed, could perform group chat operation.

So far, group's activation process is completed, and after group's activation, MSRP link MSRP_1 are set up between UE_A and IM_AS_A, MSRP links MSRP_2, GC_AS and IM_AS_B are set up between IM_AS_A and GC_AS and sets up MSRP links MSRP_3, IM_ MSRP links MSRP_4, GC_AS are set up between AS_B and UE_B and establishes MSRP links MSRP_5, M_AS_ between IM_AS_C C establishes the MSRP links MSRP_6 between UE_C.

Step S522, UE_A are by MSRP_1, to ID_1 pocket transmission chat messages；

Step S523, IM_AS_A receive the chat messages that UE_A sends past ID_1, return to 200 responses, IM_AS_A passes through Chat messages are sent to GC_AS by MSRP_2；

Step S524, GC_AS receive chat messages, return to 200 responses；According to group's information, members list is obtained, and to UE_B and UE_C sends the chat messages；

Chat messages are dealt into IM_AS_B by step S525, GC_AS by MSRP_3；

Step S526, IM_AS_B receive chat messages, returning response；IM_AS_B is sent chat messages by MSRP_4 To UE_B；

Step S527, UE_B receive the chat messages, return to 200 responses；

Chat messages are dealt into IM_AS_C by step S528, GC_AS by MSRP_5；

Step S529, IM_AS_C receive chat messages, return to 200 responses；IM_AS_C is by MSRP_6 by chat messages It is sent to UE_C；

Step S530, UE_C receive the chat messages, return to 200 responses.

In group chat flow, traditional mode has first had to group activation process, establishes UE, meeting between IM_AS and GC_AS Words, in chat process session be always maintained at, so as to cause the waste of many Internet resources.

In this application, in order to overcome the above problem, the technical solution of the application can be performed as follows.

Optionally, when receiving the MESSAGE message that the first user equipment is sent, the first user equipment sends MESSAGE and disappears Breath is forwarded to group chat server to the first application server by the first application server.The RCS group message are sent into communication group the During second user equipment where two account numbers, receiving what the first user equipment was sent by the first application server After MESSAGE message, the second application server belonging to second user equipment is determined, wherein, the first application server is the Application server belonging to one user equipment；RCS groups of message are sent to second user equipment by the second application server.

Above-mentioned is included by the second application server to RCS groups of message of second user equipment transmission：Pass through the second application Service determines the device type of second user equipment；Indicate the second application service using the device type with second user equipment The information sender formula matched somebody with somebody sends RCS groups of message to second user equipment.

Specifically, the device type for determining second user equipment by the second application service includes：Second application server Obtain the log-on message of the second user equipment pre-saved；Second application server reads the second use described in log-on message The device type of family equipment.

It indicates that the second application service is used and sends RCS with the matched information sender formula of the device type of second user equipment Group's message to second user equipment includes：In the case where the device type of second user equipment is preset kind, instruction second Application server sends MESSAGE message to second user equipment；It is not preset kind in the device type of second user equipment In the case of, the second application server of instruction establishes the first MSRP links with second user equipment, wherein, the first MSRP links It is used for transmission RCS groups of message.

It should be noted that the log-on message of second user equipment pre-saved in the acquisition of the second application server it Before, the present processes further include：When second user equipment is reached the standard grade, the second application server receives and preserves second user and sets The log-on message that preparation is sent (specific field in log-on message is used to identify device type).

Above-mentioned device type includes the pre-defined first kind and Second Type, and the second application server uses and the The matched information sender formula of device type of two user equipmenies, which sends instant communication information to second user equipment, to be included： In the case that the device type of two user equipmenies is the first kind, the second application server establishes first with second user equipment MSRP links, and pass through the first MSRP links and send instant communication information to second user equipment, complete instant communication information MSRP links are closed after transmission immediately；In the case where the device type of second user equipment is Second Type, the second application clothes Business device transmission carries the MESSAGE message of instant communication information to second user equipment.

In another optional embodiment, RCS groups of message are sent to second user equipment by the second application server Including：In the case where the length of RCS groups of message is less than preset value, the second application server of instruction sends MESSAGE message extremely Second user equipment；RCS groups of message length not less than in the case of preset value, the second application server of instruction is established and the 2nd MSRP links of two user equipmenies, wherein, the 2nd MSRP links are used for transmission RCS groups of message.

Group chat server judges whether the length of instant communication information is less than preset value；Judging instant communication information In the case that length is less than preset value, the transmission of group chat server carries the MESSAGE message of instant communication information to second should Use server；Second application server sends the MESSAGE for carrying instant communication information when receiving MESSAGE message Message is to second user equipment；In the case where the length for judging instant communication information is not less than preset value, group chat server It sends and carries the MSRP message of instant communication information to the second application server；Second application server is carried receiving During the MSRP message of instant communication information, the MSRP links with second user equipment are established, and passes through MSRP links and sends immediately Communication information is to second user equipment.

It should be noted that the group chat message (instant communication information) of the application can be divided into small messaging chat and big message Chat, small messaging chat refer to message content within 900 bytes (i.e. preset value takes 900bit), can be sent with MESSAGE Message, the group chat overwhelming majority are such cases；Big messaging chat refers to message content more than 900 bytes, disappears beyond MESSAGE The scope sent is ceased, using " SIP+MSRP " sending mode, such case is seldom.Wherein, it will be assumed that UE_A and UE_B is to support The terminal (terminal of Second Type) of the application, UE_C are the conventional terminals (terminal of the first kind) for not supporting the application.
