Description
Technical field
The present invention relates to communication technical field, be specifically related to the processing method of local service in a kind of mobile network.
Background technology
Development along with mechanics of communication, people no longer are satisfied with single voice communication mode, and multimedia communication mode that need be brand-new, this multimedia communication is not only simple video, voice communication, also comprise instant message, with the business that browses the location, business such as collaborative work, Streaming Media, particularly new traffic mode and traditional voice merge.Trend based on Internet (internet) and communication network fusion, on mobile Packet Based Network basis, introduced the IP Multimedia System (IMS) of all-IP (Internet Protocol) business network framework, be used for handling the IP multimedia service that day by day increases and control whole call flow.
IP multimedia service utilizes PS territory and multimedia to carry and realizes based on the session control ability of IETF (internet engineering task group) definition.IP Multimedia System is as CS (circuit switching) territory, PS (packet switch) territory subsystem, can finish the function such as initiation, maintenance, release of calling, also will carry out conversion and control and multimedia service is provided support media stream, it comprises a plurality of different functional entitys.
Topmost functional entity is CSCF (controlling call entity) and HSS (home subscriber server) among the IMS.According to CSCF residing position difference in network, the effect that it is born is also different, has following three types: P-CSCF (proxy CSCF), I-CSCF (inquiry CSCF), S-CSCF (serving CSCF).
P-CSCF is UE (subscriber equipment) first contact point at the IMS network, finishes Proxy (agency) function.Subscriber equipment obtains the address of P-CSCF by one " local CSCF finds flow process ".P-CSCF accepts SIP (session initial protocol message), and the request that will receive and service are handled or transmitted.The URI that P-CSCF does not ask in the INVITE to SIP makes amendment.
I-CSCF considers the network security aspect, finishes network concealed function, and I-CSCF inquired about and determines the S-CSCF that the user serves to HSS when the user registered.I-CSCF can serve as all users' of network tie point, also can be as the Service Access Point of roamer in the current network service area.In one network a plurality of I-CSCF can be arranged.
S-CSCF carries out conversation control function, and the call state of recording user is finished CCF, is topmost operation controlling entity.Different S-CSCF is because AS (application server) difference that is connected can be finished different business functions.
HSS writes down each IMS user's user profile (Subscriber Number, address information; The security information that is used for authentication and authorization; Support the positional information between user's registration, record different system; User characteristic data) and business datum (service trigger criteria and professional trigger logic), cooperate CSCF to finish most important routing function, roaming function, HSS provides authentication, mandate, IMSI (international mobile subscriber identity)/IP map addresses, position location functionality etc. simultaneously.
Mobility from IMS, when the user roams out home network, all business of user all are routed to home network by the P-CSCF on visit ground, by the S-CSCF of home network business are mapped to this locality or third party's (third party can be a network or only be an independent application server).The key of this model is the S-CSCF control customer service by home network, no matter whether the user roams, use which kind of equipment and access network, what the user was unique controls via home network, to guarantee professional consistency and simplicity, its network architecture as shown in Figure 1.
In existing mobile network's standard,, provide identical IMS local service access mechanism for home subscriber and calling party.The IMS local service is discerned by a global routable PSI (public service identity), carries out route according to normal IMS routing mode.But in some cases, the local service sign is not global routable, as uses local numbering plan, will insert local service in the following way:
(1) home network is according to the indication of receiving from user terminal UE, the address whether the decision roamer asks an IMS local service or use local numbering plan, and this indication is included among the REQUEST URI of the SIPINVITE message that UE initiates;
(2) P-CSCF is routed to service request the S-CSCF of home network;
(3) S-CSCF is according to this locality indication and certain filtering rule from UE receives, the application server AS of home network will be forwarded to before the session, AS treatment S IP URI, as adress analysis and modification (translating into global routable address format PSI), AS may need from SIP signaling or the accesses network by HSS identification user place;
(4) AS returns to S-CSCF with the session request, and S-CSCF carries out route by normal IMS routing mode, arrives the destination, as PSI corresponding server in the accesses network.
In the prior art, if the IMS local service is not to be discerned by a global routable public service identity PSI, as adopt local numbering plan, needing UE to recognize this so when initiating the IMS local service is a local service, and comprise indication in the REQUEST URI parameter in the SIP INVITE, make home network can recognize the address whether roamer asks an IMS local service or use local numbering plan.But, how to judge for user terminal whether certain business is the IMS local service, ineffective at present and unified method.

Card number service 200;
……
Step 203: user terminal is initiated the IMS service request.
Step 204: according to the IMS local service information of the current accessed network of the IMS service request address lookup record of initiating;
Step 205: judge whether the address of IMS service request is arranged in the IMS local service information of the current accessed network of record.
If exist, show that then this business is a local service, at this moment, enters step 206: in the REQUEST URI of service request SIP INVITE parameter, indicate local service.
Then, enter step 208: carry out local regular traffic and handle,, mainly comprise following process with reference to Fig. 3:
(1) P-CSCF of accesses network is routed to service request the S-CSCF of home network;
(2) S-CSCF is according to local service indication and the certain filtering rule received from UE, the application server AS of home network will be forwarded to before the session, AS treatment S IP URI, as adress analysis and modification (translating into global routable address format PSI), AS may need from SIP signaling or the accesses network by HSS identification user place;
(3) AS returns to S-CSCF with the session request, and S-CSCF carries out route by normal IMS routing mode, arrives the destination, as PSI corresponding server in the accesses network.
If there is no, show that then this business is not a local service, at this moment, enter step 207, in the REQUEST URI of service request SIP INVITE parameter, do not indicate local service.
Then, enter step 209: carry out non-local regular traffic and handle, mainly comprise following process:
(1) P-CSCF of accesses network is routed to service request the S-CSCF of home network;
(2) S-CSCF carries out route according to the non-local service indication of receiving from UE by normal IMS routing mode, arrives the destination.
In above-mentioned flow process, user terminal need indicate whether this service request is local service in the REQUEST URI of service request SIP INVITE parameter when sending service request.The present technique field personnel know, the INVITE request that is used to make a call.INVITE comprises message header and data field two parts.The INVITE head comprises main, called address information, information such as call subject and call priority; The data field then is the information about conversation media, can be realized by Session Description Protocol SDP, is mainly used in the media processing capacity of describing terminal.Wherein, whether be local service request to the URI parameter if being used to refer to.For the roamer, when the user roams out home network, all business of user all are routed to home network by the P-CSCF on visit ground, determine the address whether this user asks an IMS local service or use local numbering plan by the S-CSCF of home network according to the REQUEST URI parameter of SIP INVITE, like this, could guarantee that S-CSCF carries out correct control to customer service.
Describe the implementation process of the inventive method above with reference to Fig. 1 in detail, now be exemplified below:
For example: a U.S. mobile subscriber roams into China, register to the network of China Mobile, China Mobile its all local service information that provide is provided on the WEB server, local service information is as IP telephone service 17951, freephone 800, card number service 200......, the user obtains these local service information by visiting this WEB server, and be kept in the user terminal, write down the network identity of China Mobile simultaneously.When the user wishes to initiate IP telephone service, before normal called number, dial 17951, user terminal is analyzed according to the local service information of preserving, recognize 17951 be a local service number after, local service sign on the REQUEST URI of service request SIP INVITE parameter is mid-just.Network is handled according to normal local service handling process then.
For fear of the local service information of in user terminal, preserving too much accesses network, when roaming user terminal leaves the current accessed network, the IMS local service information of the accesses network of deletion record immediately, perhaps wait for the scheduled time after the IMS local service information of accesses network of deletion record.The concrete stand-by period is determined by operator.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
