Set scene:
Core net CN management radio network controller (RNC)；
Radio network controller (RNC) management community CELL1, community CELL2, community CELL3, belong to group's GROUP1 model
Enclose；
The calling subscribe UE1 of group GROUP1 resides in community CELL1, called subscriber UE2, and UE3, UE4 etc. are the most resident
At community CELL1, community CELL2 and community CELL3；
It is illustrated in figure 1 the flow chart of data processing schematic diagram of the present embodiment, specifically comprises the following steps that
Step 110, calling subscribe initiates to set up the request message of group GROUP1 to system side, and request message is turned by RNC
Give core net, after core net ruling, notify that RNC sets up group's related resource；
Step 120, RNC sets up the related resource of group GROUP1, including logic channel resource, transmission channel resources and
Physical channel resources；Specific as follows:
Group DCCH TDCCH1, mainly carries signaling data and part calling subscribe that called subscriber is correlated with
Relevant signaling data, corresponding RLC entity uses RLC UM pattern；It addition, TDCCH1 is mapped to transmission channel DCH1；
Group DCCH TDCCH2, the signaling data that main carrying calling subscribe is correlated with, corresponding RLC entity uses
RLC AM pattern；It addition, TDCCH2 is mapped to transmission channel DCH1, and its priority of logical channels meets TDCCH2 ＞
TDCCH1；
Group's dedicated data channel TDTCH1, TDTCH2 and TDTCH3, carry 3 subflows of speech data respectively, point
It is not mapped to transmission channel DCH2, DCH3 and DCH4；
About physical channel resources, RNC can set up community CELL1 in group range, community CELL2 and community simultaneously
The physical channel resources of CELL3；Can also only set up the physical channel resources of calling subscribe place community CELL1, wait until to confirm
Community CELL2 and community CELL3 resettles its corresponding physical channel resources when having called subscriber.Wherein, for calling subscribe
Community, place CELL1, RNC need to set up up-downgoing resource simultaneously；And for non-calling subscribe place community CELL2 and community
CELL3, RNC have only to set up downlink resource.
Step 130, RNC responds calling subscribe by common signal channel and sets up the request of group GROUP1, wherein carries group
Related resource configuration information, until calling subscribe responds after group sets up completion message, RNC notifies group by beep-page message
Interior called subscriber, and called subscriber group's related resource being broadcast in group by common signal channel；
Wherein, in order to time-consuming, RNC can also just respond caller before system side group resource has been not set up
