Description

Inceptive filtering regulation processing method

Technical field

The present invention relates to the communications field, relate in particular to a kind of inceptive filtering regulation processing method.

Background technology

IP Multimedia System (IP Multimedia Core Network Subsystem is called for short IMS) is based on Session Initiation Protocol (a kind of application layer protocol of the session of creating two sides or in many ways, revise, terminate).Main functional entity comprises the controlling call entity CSCF (Serving Call Session ControlFunction) of functions such as control user registration, session control among the IMS; Manage the home subscriber server HSS (HomeSubscriber Server) of user contracting data concentratedly, the application server AS (Application Server) of miscellaneous service logic control function is provided.

Fig. 1 is that IMS user's registration and user registration state are subscribed to flow chart.Relate generally to following network element and equipment: UE (User Equipment), be subscriber equipment; P-CSCF (ProxyCall Session Control Function) carries out Proxy Call Session Control Function; I-CSCF (Interrogating Call Session Control Function) carries out the query call conversation control function; S-CSCF (Serving Call Session Control Function) carries out service call conversation control function; HSS (Home Subscriber Server) carries out the signatory management function of home subscriber; AS (Application Server) moves various telecommunication services.

The IMS network uses the registration process of Session Initiation Protocol, realizes that the user inserts the IMS network.User registration success will be set up the relation between public user identity and this user's current location at home domain S-CSCF.Registration process is as shown in Figure 1, may further comprise the steps:

S102～S104, UE registers to S-CSCF.

S106～S110, S-CSCF obtains user contracting data from HSS, and storage.

S112～S116, S-CSCF make up to succeed in registration and respond and issue, and P-CSCF and UE are known user registration success.

S118～S122, S-CSCF carry out third-party registration according to the triggering rule in the user contracting data to AS, the third-party registration success, and AS returns success response to S-CSCF.The last user of S-CSCF registers completion; If need not carry out third-party registration, can directly carry out S124.

S124～S130, P-CSCF initiates login state subscription, and S-CSCF handles and subscribes to successfully, returns the subscription success response, and issues subscribing notification; P-CSCF receives after subscribing notification upgrades the user registration state success and returns the subscribing notification success response.

S132～S146, UE initiates login state subscription, and S-CSCF handles and subscribes to successfully, returns the subscription success response, and issues subscribing notification; UE receives after subscribing notification upgrades the user registration state success and returns the subscribing notification success response.

From Fig. 1 process, can find out; If the third-party registration failure causes user's registration failure (in the prior art; It is to be that SESSION_TERMINATED representes with acquiescence triggering rule in the register initial filter rule of user data that third-party registration failure causes user's registration failure); S-CSCF can initiate network and nullify, the deletion user data; If the login state subscription that this moment, P-CSCF and UE initiated is success as yet, can occur that the user is a unregistered state on S-CSCF and the HSS, UE, P-CSCF is last is registered state.This process is as shown in Figure 2, may further comprise the steps:

S202～S220, this process is identical with S102～S120.

S222, the third-party registration failure, AS returns the third-party registration failure response.

S224, the third-party registration failure causes S-CSCF to initiate the network cancellation, and S-CSCF deletes user data, and owing to the also not success of login state subscription of this moment UE and P-CSCF, UE and P-CSCF can't know that S-CSCF goes up the user and is canceled.

Above-mentioned fault generating, can make before register again during this period of time up to UE in, conversation request, non-conversation request that UE initiates all can not be successful.And because UE state registered state not still, this section period can be very long (response time of succeeding in registration half the).This defective had both caused UE, P-CSCF, S-CSCF, the last data of HSS inconsistent, caused the user can not use the serious consequence of IMS communication network again.

Summary of the invention

One or more problems in view of the above; The present invention proposes a kind of inceptive filtering regulation processing method; Overcome the defective in the existing third-party registration process, can when the third-party registration failure causes user's registration failure, make UE and P-CSCF perceive registration failure.

Inceptive filtering regulation processing method according to the present invention may further comprise the steps: whether step S302 has in the register initial filter rule of the user data that the service call session control function entity inspection is wherein preserved because the third-party registration failure causes the rule of user's registration failure; Step S304; In the initial filter criteria of user data, exist because the third-party registration failure causes under the situation of initial filter criteria of user's registration failure; Service call session control function entity carries out according to the register initial filter rule in the user data that the third party triggers and handle the initial filter criteria that the third-party registration failure causes user's registration failure, issues the response of succeeding in registration after handling the initial filter criteria that the third-party registration failure causes registration failure; And step S306, call conversation control function entity if also there is untreated register initial filter rule, then carries out third-party registration according to untreated initial filter criteria, up to handling initial filter criteria after issuing the response of succeeding in registration.

Wherein, service call session control function entity is from home subscriber server download user data and preserve.In step S304, service call session control function entity will succeed in registration to respond and be issued to proxy call conversation control function entity and subscriber equipment.In step S304, if because the third-party registration failure causes the initial filter criteria of registration failure to carry out the third-party registration failure, then no longer handle untreated initial filter criteria, service call session control function entity issues the registration failure response.In step S304, service call session control function entity is issued to proxy call conversation control function entity and subscriber equipment with the registration failure response.Wherein, inceptive filtering regulation processing method is used for IP Multimedia System.

Through method of the present invention, overcome the defective in the existing third-party registration process, can, the third-party registration failure make UE, P-CSCF, S-CSCF can handle unusual that the third-party registration failure takes place when causing user's registration failure.
