Embodiment
When certain mobile subscriber in any wireless network services need apply for a dynamic group calling, the SCP of network internal (Service Control Point, service control point) judgement user's legitimacy, by after will inquire about available group ID, and distribute to this dynamic group calling, send this group calling attribute to GCR by the interface between SCP and the GCR simultaneously, then dynamic group calling is created and is finished.
Travelling carriage enters certain Serving cell, then listens to the system message on the BCCH broadcast channel always, decodes the Cell ID of current service cell.If it is different with before Cell ID that travelling carriage is found the Cell ID of new sub-district, just this new Cell ID is issued intelligent network.This process will be maintained to that dynamic group calling is canceled or kick out after, just at this dynamic group calling duration of existence, the each occurrence positions change of all group memberships all automatically sends to intelligent network to new positional information, the positional information real-time update group call region attribute that intelligent network then sends according to the member.If find that group call region changes, then send to GCR by the interface between SCP and the GCR, order GCR carries out corresponding operation.
Exist a database to store the Cell ID of all sub-districts in order among the SCP.If SCP receives the position message message of sending from travelling carriage, then with the sub-district id information in the USSD word string as input parameter, search the Target cell that this travelling carriage will arrive, and generate new group call region attribute.If find that group call region changes, then upgrade the group call region attribute among the GCR immediately.
A dynamic group calling zone comprises two parts, the one, and the sub-district at this dynamic group calling member place, the 2nd, two sub-districts that this sub-district is adjacent.The purpose of doing like this has 2 points, and the one, for just only guarantee to carry out group calling avoiding the waste of resource in the zone that the user is arranged, the 2nd, in order to guarantee that the mobile subscriber goes to the group calling of next sub-district from a sub-district and do not interrupt.
Therefore, the group call region in the dynamic group calling business is that the current location of all group call member when applying for group calling according to the dynamic group calling applicant is set at the beginning, and along with each member's position changes, group call region also carries out real-time update.The renewal of group call region if the group call member position changes or walked out current group calling service area, just may cause the variation of group call region according to Event triggered.Therefore, group call region upgrades and is divided into two kinds, may increase some sub-district from group call region, also may be some sub-district of deletion from the zone.
Below in conjunction with accompanying drawing embodiment is described in detail.
Fig. 1 and Fig. 2 are respectively the flow chart that SCP increases by the two kinds of situations in sub-district and SCP deletion sub-district, its processing procedure all is in SCP, SCP starts this handling process according to the positional information of travelling carriage and analyzes group call region, then send updating message to GCR if the discovery group call region changes, order GCR carries out corresponding operation.
The constructive process of dynamic voice group call region is as follows:
Step 1: certain mobile subscriber initiates to apply for a dynamic group calling, and after intelligent network was received the dynamic group calling request that the user sends, SCP judged user's legitimacy;
Step 2: after user validation passed through, the available group ID of SCP inquiry distributed to this dynamic group calling, and other members to group calling send the positional information that request position information USSD word string obtains each group call member simultaneously;
Step 3: SCP analyzes and draws this dynamic group calling zone, and SCP sends to GCR with attributes such as group call region, group ID and priority by the interface between SCP and the GCR simultaneously;
When step 4: GCR receives this message, create this dynamic group calling immediately.
The real-time update way step of dynamic voice group call region is as follows:
Step 1: after certain dynamic voice group call was created and finished, network sent the USSD business request information to group call member;
Step 2: after receiving the USSD business request information of sending from network side, travelling carriage can solve this message, and the group calling ID that distributes in the USSD word string is write SIM card, by USSD service request response message current location information is returned to intelligent network simultaneously;
Step 3: if travelling carriage enters certain new Serving cell, then listen to the system message on the BCCH broadcast channel always, decode the Cell ID of current service cell; If this Cell ID is different with before Cell ID, in the time of need carrying out sub-district gravity treatment or handover, travelling carriage just reports to intelligent network with new Cell ID automatically by the USSD word string in the execution USSD service request;
Step 4 a: database of storing all sub-district Cell ID in order should be arranged among the SCP; If SCP receives the execution USSD service request position message message that sends from travelling carriage, then with the sub-district id information in the USSD word string as input parameter, search the Target cell that this travelling carriage will arrive, generate new group call region attribute; If find that group call region changes, then send updating message immediately to GCR, order GCR upgrades group call region attribute wherein.
Step 3 will be maintained to that dynamic group calling is canceled or kick out after just finish.At this dynamic group calling duration of existence, all group memberships have position change to need automatically new positional information to be sent to intelligent network at every turn, the positional information real-time update group call region attribute that intelligent network sends according to each member.If find that group call region changes, then send to GCR by the TCP/IP interface, order GCR carries out corresponding operation.
