Description
Technical field
The present invention relates to speech business field, particularly relate to a kind of speech business control method, system and relevant apparatus.
Background technology
The network architecture no longer discrimination circuit territory and the packet domain of LTE (LongTermEvolution), adopt unified packet domain framework, therefore it no longer supports traditional circuit domain speech business, but adopt circuit domain dropping (CircuitSwitchedFallback, CSFB) speech business (VoLTE) scheme or based on IMS carries out speech business, and its concrete mode is as follows:
CSFB is the transition scheme that LTE network carries out speech business.The thought of technology is when carrying out the UE under LTE covering in processed voice business, terminal first return back to CS (circuit domain) network, in the speech business of CS network processes, reach and reuse existing CS territory equipment for the user in TD-LTE network the object of traditional speech business is provided.
VoLTE voice scheme is the ultimate solution of operator.The core business net control of VoLTE is IMS (IP Multimedia System) network, coordinates LTE and EPC real-time performance end to end based on voice, the video communication service of packet domain.By the control of IMS system, VoLTE solution can provide the speech business suitable with circuit domain performance and supplementary service thereof, comprising: number display, call forwarding, Call Waiting, conference telephone etc.
Figure 1 shows that the structure chart of EPC and IMS (IP Multimedia System), wherein, CSCF (conversation control function) is positioned at the key-course of IMS network, according to different functions, CSCF is specifically divided into P-CSCF (Proxy-CSCF acts on behalf of session control), I-CSCF (Interrogating-CSCF, inquiry session control), S-CSCF (Serving-CSCF, serving session control), AS is application server.
LTE terminal selects CSFB or VoLTE as voice solution, be depend on network side MME to adhere to CSFB and the VoLTE ability instruction accepting to issue respectively in (AttachAccept) message or tracing section updating acceptance (TAUAccept) message, then terminal selects the voice solution of correspondence to carry out speech business in conjunction with the configuration of oneself.
In current mechanism IMS network equipment break down after EPC treatment mechanism, when mainly by link detecting, P-GW finds that some P-CSCF are unavailable, notification terminal switches to other P-CSCF to carry out speech business.But if all P-CSCF other network elements that are all unavailable or IMS domain of IMS domain break down when causing IMS domain normally cannot support the VoLTE speech business of user, the VoLTE speech business of user cannot continue.But, because terminal cannot the failure condition of sensing network side VoLTE ability, cause terminal to continue to use VoLTE voice scheme, thus cannot audio call be realized, have a strong impact on Consumer's Experience.
