Background technology
Demand along with development of Communication Technique and user has produced 'no disturbance ' service, mainly is user when not wishing to have calling to disturb, and can use this business.
At present, the basic skills that realizes 'no disturbance ' service is, by in position request response, carrying AccessDeniedReason (admission reject reason) parameter, refuse to call out, but according to present CDMA (code division multiple access) agreement, this kind method can't distinguish situations such as 'no disturbance ' service and shutdown, because be not specifically designed to the field of 'no disturbance ' service in the agreement.So just can't carry out special audio playback to caller, tell caller accurately, calledly wish interruption-free at present, be not sound very accurately and can only put called shutdown etc. to caller, as, " user that you dialed shuts down " etc.
For addressing this problem, it is the parameter of expansion locreq (position requests) message that a kind of technology is arranged at present, increase an interruption-free parameter, represent this calling interruption-free, after MSC (circuit domain core network element) receives locreq message, know it is 'no disturbance ' service according to this interruption-free parameter, thereby play corresponding interruption-free prompt tone, as " user that you dialed does not wish to be disturbed " etc. to the calling subscriber.
But, can there be following shortcoming in this processing method: realize complexity, promptly adopt this method, the change of existing equipment is very big, all MSC in the whole communication network and HLR (attaching position register) need change, and need the encoding and decoding of change standard agreement message.If there is MSC not make amendment, when this MSC receives such interruption-free parameter,, can cause this call failure so owing to can not discern the interruption-free parameter, thereby make the calling subscriber not only can't hear the prompt tone of interruption-free, also can't hear other any prompt tones.
Summary of the invention
The invention provides a kind of method and system that realize special audio playback of Do Not Disturb Service, by the expanding value of the admission reject cause parameter in the Extended Protocol, whether be 'no disturbance ' service, and need not additionally to increase parameter if making MSC to judge.
Technical scheme of the present invention may further comprise the steps:
Steps A: HLR is that to send the interruption-free message carry admission reject parameter expanding value be the circuit domain core network element to MSC to attaching position register;
Step B:MSC analyzes inserting rejection parameter expanding value, when confirming that described admission reject parameter expanding value is 'no disturbance ' service, plays the prompt tone of 'no disturbance ' service and gives the calling subscriber.
Further, in the said method, steps A may further comprise the steps:
Step 1, MSC sends location request message to HLR;
Step 2, HLR judges whether the called subscriber opens 'no disturbance ' service; When if described called subscriber has activated 'no disturbance ' service, admission reject parameter expanding value is carried in the interruption-free message, and sends to MSC.
Further, in the present invention, step 2 also comprises: if described called subscriber does not activate 'no disturbance ' service, then send corresponding message to MSC.
Further, in the present invention, HLR sends corresponding message to MSC and comprises: called subscriber's shutdown message, called subscriber can normally insert message related to calls.
The present invention also provides a kind of system that realizes special audio playback of Do Not Disturb Service, comprising:
The interruption-free message sending unit is used to send the interruption-free message that carries admission reject parameter expanding value; Analytic unit is used for described admission reject parameter expanding value is analyzed, and when confirming that described admission reject parameter expanding value is 'no disturbance ' service, triggers the playback unit; The playback unit is used to play the prompt tone of 'no disturbance ' service to the calling subscriber;
The interruption-free message that interruption-free message sending unit among the HLR will carry admission reject parameter expanding value sends to the analytic unit among the MSC, analytic unit is when confirming that described admission reject parameter expanding value is 'no disturbance ' service, trigger the playback unit among the MSC, carry out playback to the calling subscriber.
Further, in the present invention, described system also comprises:
The location request message transmitting element is used to send location request message; Judging unit is used to judge whether the called subscriber opens 'no disturbance ' service, when confirming that described called subscriber has activated 'no disturbance ' service, triggers the interruption-free message sending unit;
Location request message transmitting element among the MSC sends location request message to the judging unit among the HLR, is used to judge whether the called subscriber opens 'no disturbance ' service, if the called subscriber has opened 'no disturbance ' service, then triggers the interruption-free message sending unit among the HLR.
In sum, the invention provides a kind of method and system that realize special audio playback of Do Not Disturb Service, by the expanding value of the admission reject cause parameter in the Extended Protocol, whether be 'no disturbance ' service, and need not additionally to increase parameter if making MSC to judge; The present invention does not need to increase the parameter of agreement, realizes simple; Having solved existing equipment changes bigger, MSC and HLR need change, and need change standard agreement message encoding and decoding problem and when utilizing method and system of the present invention to carry out 'no disturbance ' service, in the communication system upgrading process, even there is MSC not carry out the configuration of admission reject parameter expanding value, so when this MSC receives such admission reject parameter, even can not discern described admission reject parameter expanding value, but can not cause this call failure, can not bring any negative effect the proper communication between the user.

Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Core concept of the present invention is, HLR is judging need carry out 'no disturbance ' service the time, transmission carries the interruption-free message of admission reject cause parameter expanding value, thereby makes calling subscriber's MSC can know this professional interruption-free, and plays the prompt tone of interruption-free to the calling subscriber.
Fig. 1 is the schematic flow sheet of the method for the invention; Be provided with user's NND ('no disturbance ' service) in HLR, this flow chart may further comprise the steps:
Step 101, MSC sends LOCREQ (position requests) message to HLR.
Step 102, described HLR receives described location request message, and judge whether described called subscriber activates 'no disturbance ' service, if the called subscriber has activated 'no disturbance ' service, described HLR is at the LOCREQ response message, be in the interruption-free message, carry the admission reject cause parameter that includes expanding value, and send described interruption-free message to MSC; Described expanding value can be arranged according to actual conditions, such as, described expanding value can be " 7 ", is used for representing that the called subscriber has activated 'no disturbance ' service; If described called subscriber does not activate 'no disturbance ' service, then send corresponding message to MSC; Described corresponding message comprises: called subscriber's shutdown message, called subscriber can normally insert message related to calls.
