A kind of method and system of service user to join in group-calling
Technical field
The present invention relates to communication technique field, relate in particular to a kind of method and system of service user to join in group-calling.
Background technology
Voice group call service (VGCS) is to realize that a plurality of people can talk (6 speakers comprise speaker's service-user and 5 dispatchers at the most), can the understand business of (hearer's quantity is unrestricted) of more people; Wherein, the dispatcher is the fixing or mobile subscriber who is identified as the dispatcher in network; Voice Broadcast Service (VBS) is to realize 1 people's speech (having only 1 speaker), a plurality of people's obedient (hearer's quantity is unrestricted) business.The voice communication mode of the point-to-multipoint that VGCS, VBS realized the some people speech, listen to has in many ways broken through the limitation of point-to-point communication, can set up calling fast.
In the prior art, Group Call Register (GCR) is realized group-calling service with mobile services switching centre (MSC), wherein GCR is used for preserving the group calling attribute data, also preserve whether ongoing sign of current group calling, when group calling is initiated, when MSC will initiate the attribute data of group calling to the GCR inquiry, GCR is provided with the state of initiation group calling for carrying out (On-going), when group calling finished, MSC notified GCR, and the state that GCR is provided with this group calling is idle (Idle).
When group calling was initiated, MSC was when GCR inquiry group calling attribute data, if GCR checks that the state of the group calling that will initiate is On-going, then notifying this group calling of MSC is On-going.If service-user is initiated group calling, then the MSC refusal is called out, and notice calling business user " user is busy "; If the dispatcher initiates group calling, then MSC directly is linked into this dispatcher in the group calling of On-going.
When group calling began to set up, network side was set up a group-calling channel in each sub-district in group call region, and notice (notification) message will go up broadcasting by the notification channel (NCH) of each sub-district in group call region; The position of NCH can obtain from the system message of Broadcast Control Channel (BCCH); Notification message content comprises that group call reference, group-calling channel are described, calling strengthens multilevel precedence (EMLPP) and cryptographic keys.In order to allow the late comer to add in the group calling, to continue in the group-calling process to send a notification message, in group call region, dial group ID when service-user like this and initiate certain group calling, MSC inquiry GCR learns this group calling well afoot, refuse the calling that this service-user is initiated, cause value is filled out and is " user is busy ", and this service-user can be sought notification message and added this group calling on the NCH channel this moment; Wherein group call region is the gang sub-district that predefine calls out for a specific VGCS in the network, and with the numerical value sign, this is designated group call region ID; Group ID is the numerical value of service-user marshalling, and service-user is divided into different function groups, with group ID sign.
The shortcoming of prior art is:
Group calling is in setting up process, and the group-calling channel of some sub-district may distribute failure, such as, the higher available TCH resource etc. that causes not having that assignment message is lost because link load causes group-calling channel, wireless channel is loaded;
Group calling is carried out in the process, the group calling passage of some sub-district also may discharge unusually because of some reason, such as, when service-user uses the up speech of group-calling channel, if the cause value of BSS in up release indication (UPLINK RELEASE INDICATION) message that MSC reports is not to call out control (Callcontrol) or wave point failure (Radio interface failure), MSC can discharge the group-calling channel of this sub-district; Being released in the sub-district of group-calling channel is the Notification message of not broadcasting the group call reference that comprises this group calling and group calling channel bank descriptor; After causing certain group calling to be set up, if when having service-user just in this group-calling channel is not set up successful sub-district, to attempt initiating the ongoing group calling of other user, MSC is the calling of this service-user initiation of refusal directly, and this service-user can not find the Notification message of the group call reference that carries this group calling this moment on the NCH channel of this sub-district, causes this service-user can't add this group calling.
