Abstract
The present invention provides a P-CSCF calling forbidden user identifying method and system which is used in an IP multimedia subsystem, wherein, the method comprises the following processes: during the S-CSCF inception registering process of the equipment of the user, the S-CSCF carries the information of the calling forbidden user in a response message of a structural registering success; after receives the response message of registering success, the P-CSCF updates the information of the calling forbidden user and the information of the non-forbidden user according to the response message of registering success; when a home subscriber server informs the S-CSCF that the identity identification of the user is revised as the calling forbidden, the S-CSCF carries the information of the calling forbidden user in a structural subscribed informing message; after receives the subscribed informing message, the P-CSCF analyzes the subscribed informing message, to update the information of the calling forbidden user and the information of the non-forbidden user.
Description
Technical field
The present invention relates to the communications field, and particularly, (Proxy Call Session Control Function, P-CSCF) identify forbidden is called out (barred) user's method and system to relate to proxy call conversation control function entity in the IP Multimedia System.
Background technology
IP Multimedia System (IP Multimedia Core Network Subsystem, IMS) user need at first register if carry out session, and the process of registration is exactly that the position of oneself is registered on network.
(Notify) mechanism of subscribing to (Subscribe)/notify makes network entity can subscribe to certain resource status, when resource status modification, is responsible for the network entity of resource and can notifies the subscriber.After succeeding in registration, P-CSCF (Proxy Call Session Control Function, Proxy Call Session Control Function) can be to S-CSCF (Serving Call Session ControlFunction, service call conversation control function) sets up the subscription of user registration state, like this, after user registration state changed, S-CSCF can notify P-CSCF, guaranteed the consistency of whole network data.If revised user configuration information, HSS (Home SubscriberServer, home subscriber server) needs to send user data synchronization request (PPR) and gives S-CSCF, simultaneous user's information.
An IMS user can have a plurality of publicly-owned identify labels, and wherein, the publicly-owned identify label of barred (forbid call out) can be initiated registration, be nullified, but can't make a call, multimedia conversation business such as subscription.
Fig. 1 is IMS user's register flow path figure, and Fig. 2 is the subscription flow chart of P-CSCF to user registration state, and known P-CSCF exhales user's handling process to see accompanying drawing 3 to the beginning.Relate generally to following network element and equipment: subscriber equipment (User Equipment, UE), P-CSCF, I-CSCF, S-CSCF, HSS.
At present, IMS user's register flow path is seen Fig. 1, may further comprise the steps:
101, UE sends register requirement to P-CSCF, has the publicly-owned identify label of user in the request;
102, when P-CSCF receives register requirement, dispose the I-CSCF (Interrogating Call SessionControl Function, inquiry CSCF) that finds the user attaching Network Access Point by DNS inquiry or this locality, and register requirement is forwarded to I-CSCF;
103, I-CSCF sends a request message to HSS, and request distributes S-CSCF;
104, HSS returns the ability of the S-CSCF name or the S-CSCF of distribution to I-CSCF;
105, I-CSCF sends to selected S-CSCF with login request message;
106～116, if S-CSCF need carry out authentication to the user, need so to obtain the authentification of user vector to HSS, and according to the Ciphering Key that returns in 107 message, structure challenge request (401 Unauthorized message) is after this challenge request is forwarded to UE, UE constructs challenge responses, after S-CSCF receives 115 challenge responses message, judge user's legitimacy, finish authentication, authentication the user; If do not need authentication, can directly carry out 117;
117, S-CSCF sends user's configuration data request of obtaining to HSS;
118, HSS stores S-CSCF information, and user's subscription data, charging address information are returned S-CSCF;
119, S-CSCF makes up the response of succeeding in registration, and response message P-Associated-URI header field value is carried all publicly-owned identify labels of user, but does not comprise the publicly-owned identify label of barred;
120, S-CSCF will succeed in registration to respond and be transmitted to I-CSCF;
121, I-CSCF will succeed in registration to respond and be transmitted to P-CSCF;
122, P-CSCF receives the response of succeeding in registration, and the information of carrying in the registration message is kept at this locality, and the response of will succeeding in registration is transmitted to UE;
Initial registration, refresh registration flow process are in full accord.Logout flow path and register flow path basically identical, just slightly different on 102, if detecting to initiate to nullify, P-CSCF do not exist, directly return failure to UE.
Known P-CSCF is shown in Figure 2 to the subscription flow process of public user login state.As shown in Figure 2, may further comprise the steps:
201, after the success of UE initial registration, P-CSCF can initiate the subscription to this user registration state;
202, P-CSCF registers the shape subscribe request to the publicly-owned identify label structure of user, and subscription request message is sent to I-CSCF;
203, I-CSCF obtains the S-CSCF address by inquiry HSS;
204, I-CSCF sends to S-CSCF with subscribe request;
205, S-CSCF constructs the success response of subscribe request, and I-CSCF is passed in response;
206, I-CSCF is forwarded to P-CSCF with response;
207, S-CSCF sends a notification message (Notify) to P-CSCF, and the login state of informing P-CSCF user does not carry the publicly-owned identify label of barred in the notification message;
208, follow-up when publicly-owned identify label login state changes, S-CSCF can initiatively send the Notify notification message, and the publicly-owned identify label of barred is not carried in the change of notice P-CSCF user registration state in the notification message;
209, P-CSCF receives the Notify notification message, upgrades local user's information, replys success response.
Known P-CSCF exhales user's handling process shown in Figure 3 to the beginning, as shown in Figure 3, may further comprise the steps:
301, UE sends conversation request to P-CSCF, user's initiation session (conversation request can be carried a P-Preferred-Identity, and this message header is that optionally it comprises the publicly-owned identify label of this user's a registration);
302, request message arrives P-CSCF, P-CSCF can check at first whether P-Preferred-Identity exists: if there is the P-Preferted-Identity message header, whether the data in the P-CSCF inspection message header are initiation session user's a current registered publicly-owned identify label, if, then P-CSCF replaces the P-Preferred-Identity hair toward S-CSCF with an identical P-Asserted-Identity head (be used to inform S-CSCF, this publicly-owned identify label is trusty) of content; If P-Preferred-Identity does not comprise a common identity sign of having registered, then P-CSCF can delete this message header, in this case, perhaps under the situation that does not have the P-Preferred-Identity head, P-CSCF will add a P-Asserted-Identity head, its content mails to the session request message S-CSCF of user attaching then for initiating user's default publicly-owned identify label;
303～308, originating S-CSCF carries out controlling and processing services, afterwards the session request is transmitted to terminating S-CSCF, and terminating S-CSCF carries out certain controlling and processing services, and called P-CSCF is mail in request, and called P-CSCF issues called UE with the session request;
309～313, called UE is responded session and is set up successful respond to called P-CSCF, and session is set up successful respond and arrived calling UE via called P-CSCF, terminating S-CSCF, originating S-CSCF, caller P-CSCF.
By above description as can be seen, at present, the 3GPP related protocol does not propose effective solution to how to handle the publicly-owned identify label of barred at P-CSCF, therefore the technology that adopts at present exist following three obviously not unusually:
1, through P-CSCF, I-CSCF, S-CSCF, HSS, after the initial registration success, and if then barred user initiates to nullify, because P-CSCF can't get access to the publicly-owned identity information of barred, P-CSCF checks that user data does not exist, and can refuse this user's cancellation.
2, beginning exhales the user to use the publicly-owned identify label initiation session of barred, current mechanism is because P-CSCF can't discern the publicly-owned identify label of this barred, as P-CSCF during in user's initiation session, judge that the publicly-owned identify label of user that conversation message carries does not up exist, P-CSCF will revise conversation request (replace original publicly-owned identify label be a registration the publicly-owned identify label of default subscribers), and will talk about and be routed to S-CSCF, this causes the user to make a call with the publicly-owned identify label of barred also can be routed to S-CSCF by P-CSCF, and S-CSCF thinks that also this calling is legal, causes the IMS system can't forbid the calling of the publicly-owned identity of barred user.
3, HSS modification user's publicly-owned identify label is barred, initiates notice and informs S-CSCF, and S-CSCF sends subscribing notification to P-CSCF, only can carry the publicly-owned identify label of non-barred in the message, and P-CSCF can't the perception user's modification be barred.
Therefore, need a kind of mechanism that can make the effective identify forbidden calling party of P-CSCF.
