Abstract

This system consists of the serious connected grouped terminals, the dispatching console (DC), the residing register (RR) and the dispatching server (DS). DC is used to start the dynamically re-grouping request and manage grouped members. RR completes the database management and configuration functions including recording, changing and timely maintaining the dynamically re-grouping info. DS processes the grouped dispatch calls, including establishing/ deleting calls and informing terminals the group renewing info. Using this system, during the re-grouping operation, the system supervisor can set the valid period (VP) of this re-grouping operation if necessary. When VP is due, the system auto-deletes the set re-grouping operation without manual interposition.

Fig. 2 is that present embodiment is regularly cancelled reorganization group service realization flow figure.

Embodiment

The basic network framework of digital clustering communication system as shown in Figure 1, it comprises logic function modules such as colony terminal, base station sub-system BSS, dispatch service subsystem DSS.

Colony terminal links to each other with base station sub-system (BSS) by air interface, and the miscellaneous service for the user provides group system also provides traditional plain old telephone service, short message service and data service for the user simultaneously.

Base station sub-system BSS (Base Station Subsystem) mainly finishes various group services, the wireless access function of data service and plain old telephone service.BSS constitutes by base station transceiver BTS (BaseTransceiver System), base station controller BSC (Base Station Controller) and dispatching client PDC (PTT Dispatching Client) are common.Wherein radio receiving-transmitting unit BTS finishes the function such as modulation and demodulation, radiofrequency signal transmitting-receiving of baseband signal, base station controller BSC is finished all kinds of switchings of wireless resource allocation, call treatment, power control and support terminal, and scheduling controller PDC then finishes wireless resource allocation, dispatch call control, power control, supports all kinds of switchings under the different areas of coverage of colony terminal, compiles and distribute the cluster audio data stream.

Switching subsystem MSS (Mobile Switch Subsystem) mainly finishes phone interconnect services, common telephone call business and part value-added service.MSS is made up of moving exchanging center MSC (MobileSwitching Center) and attaching position register HLR (Home Location Register) etc.

Dispatch service subsystem DSS (Dispatching Service System) mainly finishes colony dispatching service, is made up of PTT dispatch server PDS (PTT Dispatch Server), PTT home location register PHR (PTT Home Register), scheduling proxy server DAS (Dispatching Ageng Server) and scheduling proxy client DAC (Dispatcher Agent Client).

PTT dispatch server PDS is the master control point of trunked call, is called dispatching control center again, finishes the processing of colony dispatching calling, comprises the discriminating cluster user, sets up various trunked calls such as individual call and group call, judgement cluster PTT request etc.PDS also receives the cluster speech data of reverse link as dispatch server, is distributed to corresponding forward link again according to the character of calling out.

PTT home location register PHR finishes data base administration and configuration feature, for cluster user provides group registration, group member registration, and provides the local information of cluster member and the service authority record of cluster member, finishes call statistics and billing function.

Scheduling proxy server DAS can initiate and participate in dispatching servicess such as dynamically interim reorganization and permanent reorganization, and can realize the management function of group member etc.Dispatching desk is made up of scheduling proxy client DAC and scheduling proxy server DAS, and client is responsible for the scheduling operation request of receiving scheduling platform and is submitted to server, and server is handled above-mentioned request.

Whether dynamic reorganization produces new group according to operation is divided into two types substantially:

Type A: group (or user) is added in the existing group;

Type B: group (or user) is added new the establishment in the group.

Fig. 2 shows the flow chart that present embodiment is regularly cancelled the reorganization group service, and concrete steps are as follows:

Step 201, scheduling proxy client DAC carries dynamic reorganization expiration time information and dynamic recombinant type sign (type A or type B) to dynamically reorganization request of scheduling proxy server DAS transmission in this request message;

If dynamic recombinant type A then also carries female group identification in the message.

Step 202, DAS upgrades the dynamic reorganization expiration time in the PHR database;

For the dynamic reorganization operation of type A, DAS upgrades the female group that stores in the PHR database expiration time of dynamically recombinating according to female group identification;

For the dynamic reorganization operation of type B, DAS creates the dynamic reorganization expiration time that new group upgrades this group more earlier in PHR.

Step 203, PHR recombinates respectively in fixing duration scan database that group recombinates dynamically whether expiration time has expired or is expired, if, then remove user or the group in the dynamically reorganization group and notify PTT dispatch server PDS from database, this is cancelled group's notification message and comprises the dynamic recombinant type (type A or type B) that is eliminated group and user that need cancel or group identification tabulation;

Step 204, PDS receive PHR cancel group message after, judge whether female group is in the conversation, cancelled this time calling out of user or group if then cancel, carry out next step, otherwise, directly carry out next step;

For type A, if inquiring about female group, PDS is in the conversation, then reversed user or group scheduling are gone out this calling, execution in step 205;

For type B, if inquiring about female group, PDS is in the conversation, then cancel this calling, execution in step 205 again.

Step 205, group information was changed under PHR informed terminal by PDS, the group information updating of triggering terminal, terminal is obtained current affiliated group information and record in real time by group information updating.

PHR can upgrade or other modes inform that endpoint groups information changes by the position.

In sum, dynamically reorganization is by authorizing dispatching desk to initiate, and subsequent operation is instructed according to dispatching desk by system and finished automatically, does not need manual intervention.The system manager can be provided with the useful life that dynamic reorganization generates information, and after the useful life that is provided with arrives, system will cancel this information automatically.
