Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method and control appliance of replay call.
Background technology
In global system for mobile communications (GSM, Global System for Mobile communications), no matter caller is done at terminal (like equipment such as mobile phones) is still done called; When access network; Article one message when the access communications network is channel request channel request message, after base station controller (BSC, Base Station Controller) is received this message; Judge whether idle signaling channel (sdcch, Standalone Dedicated Control CHannel); If idle signaling channel is arranged, then BSC can issue immediate assignment message and give the terminal, lets terminal transfer to this idle sdcch, makes the terminal on said idle sdcch, send relevant service call message.If in follow-up handshaking procedure, BSC receives the assignment request of core net control appliance, can once more terminal transfer be arrived on the special-purpose speech channel channel (tch, Traffic CHannel).
Whether yet can't distinguish in the channel request message is the high priority terminal.Therefore,, will cause the calling at this terminal of BSC refusal, thereby influence the timely access at high priority terminal in case sdcch is congested.
And under special circumstances, for the calling that initiate at some high priority terminals, require when channel resource can not satisfy current all communication requirements, still can guarantee to obtain channel resource, reach in time communication objective.Said high priority terminal is meant need be by the terminal of preferential replay, and for example when disasters such as earthquake took place, some disaster relief personnel's calling needed priority treatment etc., and this Terminal Type is through the information of priority is set in advance.Corresponding with the high priority terminal is ordinary terminal, and ordinary terminal is not provided with the priority of calling, when channel resource occurring and can not satisfy active user's calling, and can be by the call seizing at high priority terminal.
In order to guarantee the calling under the state of emergency; GSM/ third generation collaborative project (3GPP; Third Generation Partnership Project) network protocol specifies the terminal can initiate urgent call; Urgent call described in the present specification is meant the urgent call of GSM/3GPP agreement regulation, for example urgent calls such as 112 or 911.When the user dials 112 or 911, in channel request message, can indication be urgent call, like this, BSC just can this calling of preferential replay, and while core net control appliance also can this calling of priority treatment.After the core net control appliance is received emergency call request, can route calls to EC, the user just can converse with EC like this, such as reporting to the police etc.
The inventor finds that in the research process to prior art prior art can only route the call to EC, calls and can not directly call the quilt that the user hopes.Such as, the party A-subscriber hopes to call out the party B-subscriber, if but initiate ordinary call, when network congestion, this calling possibly be dropped and can't insert.If but used urgent call, could only be routed to EC again.If through EC on behalf of being transferred to the party B-subscriber, the one, inconvenient; The 2nd, number is handled in the speech channel of EC has restricted number, the calling that need continue when the high priority terminal very for a long time, EC just can not in time be handled, and has influence in time continuing of high priority terminal urgent call.
