Abstract
The present invention discloses a processing method for the call originating of unregistered users, which comprises the following steps that S402, the calling subscriber unregistered condition is informed to an agent-call session control function module in the condition that a interrogating-call session control function module or a serving-call session control function module learns that the calling subscriber is an unregistered subscriber; S404, the unregistered condition of the calling subscriber is informed to a subscriber equipment, and the registration information of the calling subscriber is deleted or not deleted after the agent-call session control function module learns the unregistered condition of the calling subscriber; and S406, a registration process is reinitiated or finished after the subscriber equipment learns the condition that the calling subscriber is unregistered. Through the present invention, the problem that the subscriber data inconsistency caused by network logout under the situations that the registration status subscribing is not built and the building is failing can be solved.
Description
Technical field
The present invention relates to the communications field, relate more specifically to a kind of processing method that is used for the call from unregistered user of IP Multimedia System.
Background technology
IP Multimedia System (IP Multimedia Core Network Subsystem, be called for short IMS) dialogue-based initiation protocol (Session Initiation Protocol, be called for short SIP, it is a kind ofly to create two sides or in many ways, revise or the application layer protocol of the session that terminates).Major function entity among the IMS comprises: controlling call entity (the Serving Call Session Control Function that is used to control functions such as user's registration and session control, abbreviation CSCF), be used to manage concentratedly home subscriber server (the HomeSubscriber Server of user contracting data, be called for short HSS) and the application server (Application Server is called for short AS) that is used to provide miscellaneous service logic control function.
Fig. 1 shows the flow process of IMS user's registration and user registration state subscription.As shown in Figure 1, this flow process relates generally to following network element and equipment: subscriber equipment (User Equipment, abbreviation UE), proxy call session control function module (Proxy Call Session ControlFunction, abbreviation P-CSCF), module with query calling session controlling function (InterrogatingCall Session Control Function, abbreviation I-CSCF), service call conversation control function module (Serving Call Session Control Function is called for short S-CSCF), HSS and AS.
The IMS network uses the registration process of Session Initiation Protocol to realize that the user inserts the IMS network.User registration success will be set up relation between public user identity and this user's current location at home domain S-CSCF.Registration process may further comprise the steps as shown in Figure 1:
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's registration of S-CSCF is finished; If do not need to 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 subscribing notification, returns the subscribing notification success response after the success of renewal user registration state.
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 subscribing notification, returns the subscribing notification success response after the success of renewal user registration state.
From process shown in Figure 1 as can be seen, if the third-party registration failure then can cause 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 not as yet successfully, the last user of S-CSCF and HSS then can occur is unregistered state, is the situation of registered state on UE, the P-CSCF.This process may further comprise the steps as shown in Figure 2:
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.
From process shown in Figure 2 as can be seen, after if UE succeeds in registration, UE and P-CSCF subscribe to failure (, S-CSCF load congested suddenly as network is excessive etc.) to user registration state, then the S-CSCF network of initiating nullify UE and P-CSCF can't perception, the last user of S-CSCF and HSS will occur is unregistered state, and the last user of UE, P-CSCF is the situation of registered state.This process may further comprise the steps as shown in Figure 3:
S302～S322, this process is identical with S102～S120;
S324, S-CSCF burst load is excessive, reaches the processing upper limit;
S326-S336, P-CSCF and UE send the login state subscription request to S-CSCF, and S-CSCF returns failure response owing to reach the processing upper limit to P-CSCF and UE;
S338, HSS sends the deletion user data requests to S-CSCF;
S340, S-CSCF deletes user data, and the login state subscription of UE and P-CSCF is failed owing to this moment, goes up the situation that the user has been canceled so UE and P-CSCF can't be known S-CSCF;
S342, S-CSCF is to the success response of HSS loopback deletion user data.
Above-mentioned fault produces, can make before UE re-registers during this period of time in, conversation request, non-conversation request that UE initiates all can not be successful.And because the UE state still is a registered state, so this section period can very long (half of the response time of succeeding in registration).This defective had both caused UE, P-CSCF, the last data of S-CSCF, 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 invention provides a kind of processing method that is used for the call from unregistered user of IP Multimedia System.
