It comprises: 1) call control entity receives a request for canceling the user, which contains cancellation reason; 2) judging the type of session and the reason value of cancellation; 3) according to the type of session and the reason value of cancellation, deciding if releasing the session.
Description
Technical field
The present invention relates to communication technical field, more specifically, relate to a kind of method that is used for the session between controlling call entity (Call Session Control Function is abbreviated as " CSCF ") release and the user.
Background technology
SIP (Session Initiation Protocol, session initiation protocol) is the standard of the Internet engineering duty group (IETF) in a kind of VoIP of in March, 1999 issue.SIP has increased a kind of important application of phone as the Internet (Internet) requirement of telephone signaling and service quality (Quality of Service is called for short " QoS ") aspect, and has had the unique user's addressing and the function of location.Recently, the practical function of SIP head and shoulders above the application of VoIP (Voice Over IP, transporting speech on IP network).SIP is the agreement of telephone signaling, be used for initiation session, the foundation and the termination of the Multimedia session of can a plurality of participants of control participating in, and can dynamically adjust and revise session attribute: as the code/decode format of session bandwidth requirement, transmission medium type (voice, video, data etc.), medium, to support of multicast and clean culture or the like.Therefore, SIP helps combining with the Internet value-added service of the multiple application of exploitation.
The IMS of correlation technique is described with reference to Fig. 1 below.
Fig. 1 shows the framework of the IMS 100 of correlation technique.
IMS (IP Multimedia Subsystem, IP Multimedia System) is 3GPP (3rdGeneration Partnership Project, 3rd Generation Partnership Project) subsystem that on packet network, superposes, adopt the bearer path of packet domain for its control signaling and media delivery, introduce Session Initiation Protocol as professional control protocol, utilize simple, the easy expansion of SIP, media combination characteristics easily, by business control is separated with carrying control, provide abundant multimedia service; Main functional entity comprises controlling call entity CSCF (the Call Session ControlFunction of functions such as control user registration, session control among the IMS, CSCF), HSS (the Home Subscriber Server of centralized management user contracting data, home subscriber server), the AS (Application Server, application server) of miscellaneous service logic control function is provided.
The IMS network uses the registration process of Session Initiation Protocol, realizes that the user inserts the IMS network.In user registration course, the IMS network authenticates and sets up the input field escape way at IP multimedia private identity, user registration success will be at home domain S-CSCF (Serving CSCF, the service call controlled entity) set up relation between IP multimedia pUblic identity and this user's current location, S-CSCF takes off user's subscription data simultaneously from HSS.
The IMS system architecture as shown in Figure 1.
As shown in the figure, the IMS system architecture has realized the fusion of PSTN (Public SwitchedTelephone Network, Public Switched Telephone Network) and traditional mobile signaling protocol net (LegacyMobile Signalling Networks).According to the request of user or network entity, CSCF can be for setting up one or more Multimedia session.According to the description of 3GPP TS 24.229, P-CSCF (Proxy-CSCF, agent call controlled entity) and S-CSCF network element need discharge session of setting up and the session of having set up by sending BYE message to the calling and called side when the user is canceled.Comprised BGCF (BreakoutGateway Control Function in the IMS framework, interrupt gateway control function), MGCF (MediaGateway Control Function, MGCF), MRFC (MultimediaResource Function Controller, Multimedia resource function controller (MRFC)), P-CSCF, SLF (Subscription Locator Function, signatory locator function), UE (UserEquipment, subscriber equipment), IMS-MGW (IMS-Media GateWay, the IMS media gateway), and MRFP (Multimedia Resource Function Processor, Multimedia resource function processor (MRFP)).
According to 3GPP TS 24.229 standards (" GPP TS 24.229 ", 3GPP standard agreement: based on the IP multimedia call control protocol of SIP and SDP; Process 3) description, as user's IMPU (IP Multimedia Public Identity, the open identity of IP multimedia) when registration lifetime expires, when perhaps network initiated to nullify, the user still need be by session of setting up to the release of calling and called side transmission BYE message and the session of having set up at the Multimedia session of activity by this IMPU initiation.
Yet the method for describing in 3GPP TS 24.229 standards can not solve some sessions of in particular cases setting up and discharge, and for example discharges for the session of setting up under the situation of urgent call, and the calling of called unregistered service can not discharge.

In step S102, S-CSCF receives the logging off users request that is used for logging off users;
In step S104, the cancellation cause value that is comprised in analysis session type and the request of analysis logging off users; And
In step S106, when logging off users, determine whether to discharge session according to conversation type and cancellation cause value.
Describe in detail according to S-CSCF user log off situation of the present invention with reference to table one and table two below, handle the method that session discharges.
1, CSCF is because the difference of type of service needs the conversation type of release to comprise following a few class:
● the session that the state that registered state is set up down is relevant: this class session can only be set up down by registered state, can not set up under unregistered state.Call Forwarding No Reply business for example;
● the following session that has nothing to do with login state that set up of registered state: this class session can be set up under registered state and unregistered state, for example the Call Forwarding Unconditional business;
● the session that unregistered state is set up down; And
● emergent session.
Specifically, CSCF can judge the three kinds of conversation type in front according to user registration state, can judge session according to the conversation request content then and whether belong to emergent session.
2, the situation of user's registration has only a kind of:
The registration that the user initiates to network, cause value is as follows:
● REGISTRATION: Client-initiated registration.
3, the situation of user log off has following several:
Client-initiated is nullified, and cause value is as follows:
● USER_DEREGISTRATION (user log off): Client-initiated is nullified.
Another controlling call entity is initiated to controlling call entity, and perhaps by the inner cancellation of initiating of controlling call entity, cause value is as follows:
● TIMEOUT_DEREGISTRATION (overtime cancellation): registration timer is overtime, the cancellation that CSCF initiates; And
● ADMINISTRATIVE_DEREGISTRATION (management is nullified): the management that CSCF initiates is nullified.
The cancellation that HSS initiates, cause value is as follows:
● PERMANENT_TERMINATION (the permanent cancellation): this IMPI of HSS indication S-CSCF (IP Multimedia Private Identity, IP multimedia secret identity) Dui Ying IMPU and implicitly registered set no longer are assigned to this S-CSCF (for example, the signatory of user changes);
● NEW_SERVER_ASSIGNED (new server-assignment): this IMPU of HSS indication S-CSCF is assigned to new S-CSCF;
● this user of SERVER_CHANGE (server change): HSS indication S-CSCF kick out allows the user select other S-CSCF; And
● REMOVE_SCSCF (cancellation service call controlled entity): the IMPU of this unregistered state of HSS indication S-CSCF no longer is assigned to this S-CSCF.
It should be noted that the situation of the cancellation of initiating about HSS, controlling call entity can only be S-CSCF, and can not be P-CSCF.
4, under the situation that user registration state changes, the session processing mode of having set up is as follows:
The session that the user sets up under unregistered state, if follow-up during session, User Status is changed to registered state by unregistered state, network does not discharge these sessions.If follow-up during session, User Status is changed to unregistered state once more by registered state, and the cause value of then network based conversation type and release different selectively discharge session.Concrete grammar is participated in following form:
