Embodiment
With reference to figure 1, this figure is the preferred embodiment flow chart of group of the present invention recombination method.
Group in the present embodiment after the reorganization can be described as reorganization group, group's reorganization can be initiated by dispatching desk, dispatching desk has an operation interface, and attend a banquet (similar 1860 the customer service representatives) of dispatching desk can send the request message of dynamically recombinating to TSC (step S101) by operation interface; TSC if satisfy the reorganization condition, then starts group's reorganization (step S102) after receiving dynamic group reorganization request message.
Usually, the Media Call Control Unit of TSC is finished dynamic reorganization, since in Media Call Control Unit each group call (or session) corresponding a call control block, start in the present embodiment group's reorganization at first the counterweight set condition judge, promptly the group number of each group to be recombinated in the reorganization request according to dispatching desk judges whether to exist the session (i.e. Dui Ying call control block) of each group's correspondence described to be recombinated; If judged result is for being, the session of group's correspondence promptly to be recombinated exists entirely, and dispatching desk has the reorganization authority, then determines to start group and recombinates; And, then can notify the dispatching desk reconstructing failure if judged result for not, has one session not exist in 2 groups for example to be recombinated, in addition,, also can notify the dispatching desk reconstructing failure if dispatching desk does not have authority to do the dynamic group reorganization.
The existing interface-free resources that need not remove the group to be recombinated that has set up in the present embodiment is recombinated, after the reorganization of above-mentioned definite startup group, can create a new call control block (promptly creating the call control block of reorganization group correspondence) (step S103), described call control block of recombinating group's correspondence stores the reorganization group information, described reorganization group information comprises that mainly the Traffic Channel of the group that each is to be recombinated corresponds to the group informations of having set up before its reorganization such as Traffic Channel, promptly comprise reorganization group member information, for example the recombinate right of speech priority of group member, each reorganization group member sends the link informations such as Traffic Channel at right of speech place; Call control block in the described reorganization of establishment group correspondence is finished the response message (step S104) that just can recombinate and finish for the dispatching desk loopback.
Need illustrate, after starting group's reorganization, need also to judge current whether the someone talks, and whether needs to do right of speech ruling (not illustrating in the drawings), for example, then need to determine the group user to be recombinated that obtains right of speech by ruling if a plurality of group user to be recombinated initiation session is simultaneously arranged; Then can be transmitted to the user of the described group that recombinates by the Traffic Channel of having set up before the reorganization of network entity such as (PCF) of Packet Control Function entity by group's correspondence respectively to be recombinated for described right of speech ruling result.
And if reorganization time nobody speech, just do not relate to the right of speech ruling yet, can just finish at the call control block of the described reorganization of establishment group correspondence and can give the dispatching desk loopback response message (step S104) that reorganization is finished, dynamic regrouping process was finished after DPT received response message.
With reference to figure 2, this figure is the embodiment schematic diagram of a kind of cluster exchanging system network environment that two groups are arranged of using of the present invention.
In general cluster conversation, each group takies N forward/reverse-primary channel (Forward/Reverse Fundamental Channel, F/R-FCH) and 1 forward supplemental channel (Forward Supplemental Channel, F-SCH), as shown in Figure 2, in the present embodiment, group 1 and group 2 have been in the session, respectively taken 1 forward shared channel, wherein group 1 takies F-SCH1, and group 2 takies F-SCH2.
In each cluster conversation, the travelling carriage of each group user (MS) sends the right of speech request and transmits voice by R-FCH, transmit right of speech notice and voice messaging by F-SCH, for example group 1 and group 2 take a F-SCH (being respectively F-SCH1 and F-SCH2) respectively and are used for transmitting right of speech notice and voice messaging downwards in the present embodiment, and each group user is all used a R-FCH when upwards transmitting right of speech request and voice messaging separately.
With reference to figure 3, this figure is the present invention carries out group's recombination method at a cluster switching system shown in Figure 2 embodiment flow chart.
The dynamic reorganization of group can be initiated from dispatching desk (DPT) by the dispatcher in the present embodiment, when the dispatcher initiates dynamically reorganization because of service needed by DPT, DPT sends dynamically reorganization request message (step S201) to TSC, dynamically the group number of group 1 and group 2 is carried in reorganization request message the inside, TSC carries out group's reorganization (step S202) after receiving dynamic reorganization request message, TSC is according to the group 1 of carrying inside the request message of dynamically recombinating and the number of group 2, judge whether to exist 2 sessions (whether the call control block of promptly judging the session correspondence exists), if 2 sessions of two groups to be recombinated exist, and the dispatcher has the reorganization authority, promptly satisfying under the reorganization condition, can determine to start group's reorganization, TSC can merge 2 existing groups (group 1 and group 2) the interim group 3 of generation then, described interim group 3 promptly is the final reorganization group that forms, above-mentioned existing interface-free resources of not removing group 1 and group 2 when merging, promptly the Traffic Channel of existing group 1 that will be to be recombinated in interim group 3 and group 2 corresponds to the Traffic Channel of having set up before its reorganization.
In group's regrouping process, if a plurality of group user to be recombinated initiation session is simultaneously arranged, TSC can carry out right of speech ruling (step S203), for example, MS1 is just having right of speech in the group 1, and MS3 is just having right of speech in the group 2, TSC can be by comparing MS1 and MS3 right of speech priority when group merged, the higher user of right of speech priority obtains right of speech at last, and as the user who has current right of speech in the interim group 3, and the another one user will lose right of speech.If the right of speech of MS1 and MS3 is the same, then can discharge the right of speech of MS1 and MS3 simultaneously, each user can rob power again in the interim group 3, in addition, TSC also can be with the group user a plurality of to be recombinated of the described while initiation session of ruling result notification after the power of sanction is determined, in the present embodiment can by PCF by reorganization before the F-SCH1 of the group 1 that set up with right of speech result notification MS1 and MS2 (step S204), in addition, also can by PCF by reorganization before the F-SCH2 of the group 2 that set up with right of speech result notification MS3 and MS4 (step S205).
Need explanation, after group merged, the calling right distributing method of interim group 3 was the same with the calling right distributing method of existing cluster group, repeats no more here.
After TSC finishes group's recombination and the intact right of speech of ruling, send dynamically reorganization response message (step S206) to DPT, dynamic regrouping process was finished after DPT received response message, owing to do not remove the existing interface-free resources of group 1 and group 2, promptly realized under the situation that need not adjust existing interface-free resources the group in the session being merged, interim dynamically reorganization speed is very fast.
With reference to figure 4, this figure is the method embodiment flow chart that carries out conversation dispatching in cluster switching system shown in Figure 2.
After dynamically reorganization is finished in the present embodiment, set up the reorganization group (being interim group 3) that merges, MS1 can send right of speech request (step S301) by the R-FCH of oneself, after the success of application right of speech, TSC sends right of speech notification message (step S302-S304) by group 1 and 2 each the self-corresponding F-SCH of group that set up to each user; The MS1 that obtains right of speech then can arrive TSC (step S305) by the R-FCH transfers voice information of oneself, the Traffic Channel set up before the reorganization of TSC by F-SCH1 and these groups 1 of F-SCH2 and group's 2 correspondences sends user (the step S306 of voice messaging in all interim groups 3, step S307), the interim group 3 after the also promptly dynamic reorganization occupies 2 F-SCH channels transmission rights of speech notices and voice.
Need illustrate, in the foregoing description group 1 and group 2 are merged into an interim group 3, because group 1 and group 2 have formed an interim group 3, so interim group 3 also has the characteristics of cluster, be that synchronization can only have user's speech, other member can only listen and can not say, also promptly to 3 users of interim group (being former group 1 and 2 users of group) of while initiation session, determine to obtain right of speech by ruling, for example carry out according to interim 3 users' of group right of speech priority, at first obtain a plurality of interim 3 users' of group of initiation session session priority simultaneously, then according to 3 users' of interim group of described while initiation session session priority, ruling 3 users of interim group that wherein session priority is the highest obtain right of speech, because the control of right of speech and the forwarding unification of voice are controlled by TSC, realize simpler.
