By taking the status indicator based on terminal is counted to the interested terminal quantity of communication set as an example, the embodiment of the present invention is carried
The method of confession is described in detail.
In following Application Example, every sub-regions in group communication service region are a cell.
Status indicator is set for terminal, there are four types of states for each terminal, pass through the different value bodies of its status indicator respectively
It is existing.These four states are respectively：
It is unregistered（De-registered）State：Terminal in this state should initiate registration message and be communicated to group first
Server could initiate group service；
Registration（Registered）State：The terminal that success is registered to group communication server enters Registered states,
Group communication server can send control signaling to this state terminal, such as execute dynamic reorganization process；
It is interested（Interested）State：The state is associated with the identification information of communication set, successful to group communication service
Device sends the terminal of the identification information of interested communication set, the SOT state of termination corresponding to the identification information of interested communication set
For the state, in group calling procedure, group communication server should be called for asking in terminal initiation group under this state, and inviting should
Group calling communication is added in terminal under state.
Connection（Active）State：The state is associated with the identification information of communication set, and terminal successfully initiates/and addition group calls through
Entering this state after letter, terminal under this state can receive/and transmission group exhales data.
Based on the setting of the above-mentioned SOT state of termination, in group communication, MBMS carries processing procedure such as Fig. 3 institutes of establishment stage
Show, specifically includes following operation：
Step 300a, UE sends registration message to group communication server, and interested communication set is carried in the registration message
Identification information.
Step 310a, group communication server sets the status indicator of UE to Interested, and interested logical with UE
The identification information of letter group and the identification information association of UE access cell.
Step 300b, UE removes registration message to group communication server transmission.
Step 310b, group communication server sets the status indicator of UE to De-registered.
Step 320, group communication server count in each cell in the group communication service region of each communication set to corresponding
The interested terminal quantity of communication set.
Should be pointed out that step 300a, 310a, step 300b, step 310b, with do not have between step 320 it is stringent
Sequential relationship.Group communication server is likely to be received the registration message from UE at any time, and the shape of UE is updated according to registration message
State is also likely to be received the registration message that goes from UE at any time, and according to the state for going registration message to update UE.Group communication service
Device can be counted according to the scheduled period to the interested terminal quantity of communication set, can also be united after the state of update UE every time
Count the quantity of UE.
When group communication server judges to increase to cell pair to the interested terminal quantity of some communication set in each cell
The first terminal amount threshold that the instruction carrying answered is established（Tsetup）When, step 330, group communication server are executed to BM-SC
It sends MBMS carryings and establishes request, the location information for carrying multicast area is established in request in MBMS carryings.
In the embodiment of the present invention, so-called multicast area is the subregion in the group communication service region of communication set.
The location information of the multicast area carried in request is established in above-mentioned MBMS carryings, either constituting multicast area
The identification information of cell can also be the location information for the cell for constituting multicast area, can also be according to composition multicast area
Cell location information obtain multicast area position.
It should be pointed out that embodiment shown in Fig. 3 in, only in each cell to the interested number of terminals of some communication set
Amount increases to the corresponding first terminal amount threshold of cell and illustrates as the decision condition for establishing MBMS carryings, but not only
It is limited to a kind of this decision condition.
Step 340, BM-SC are that MBMS carryings establish corresponding communication set is asked to distribute TMGI, and to group communication service
Device returns to the response message for carrying TMGI.
Step 350, group communication server safeguard the mapping relations between TMGI and communication set mark.
What step 360~3110, MBMS were carried establishes process.
At this point, the MBMS carryings of all foundation are in un-activation（Inactive）State, without carrying out bearing resource point
Match.
After establishing MBMS carryings, still suffers from UE and registered or gone to register to group communication server, correspondingly,
Group communication server is according to the statistic of UE to the interested terminal quantity of communication set.In order to further decrease to bearing resource
Waste, the MBMS of foundation carryings can also be discharged when meeting predetermined conditions, process flow is as shown in figure 4, main
It to include following operation：
When group communication server judges to reduce to cell pair the interested terminal quantity of some communication set in each cell
The second terminal amount threshold for the instruction carrying release answered（Trelease）When, step 400, group communication server are executed to BM-
SC sends MBMS carryings and removes request, and the TMGI that communication set is carried in request is removed in MBMS carryings.
Step 410, BM-SC determine that corresponding MBMS is carried according to TMGI, releasing bearing resource, returning response message.
Step 420~470, MBMS carry release process.
Since the distribution of UE is dynamic change, the terminal number in cell in group communication service region is also to become
Change, when to certain into or out cell of the interested terminal of group communication, is likely to result in group communication server to this
Cell uses different data transmission policies, that is, uses multicast or unicast, therefore when group communication server has been certain communication
Group establishes MBMS carryings and does not discharge, and monitors to reach first to a group number for the interested terminal of communication in certain cell
When terminal quantity threshold value/second terminal amount threshold, group communication server needs to adjust multicast area, i.e. group communication server needs
Initiate bearer update process the cell is included in/pick out multicast area.Its specific implementation is as shown in figure 5, including such as
