Description

Machinery of consultation of registration timeout time and re-registration method and cancellation method

Technical field

The present invention relates to the communications field, relate in particular to the machinery of consultation of registration timeout time, cancellation and customer separating method, re-registration method, reach cancellation method.

Background technology

IP (procotol, Internet Protocol, be called for short IP) IP multimedia subsystem, IMS (IPMultimedia Core Network Subsystem, be called for short IMS) be by third generation partner program (3rd Generation Partnership Project, abbreviation 3GPP) a kind of IP-based network framework that proposes, it has made up an opening and service environment flexibly, supports multimedia application, and provides abundant multimedia service for the user.

IMS is based on the communication network framework of IP, irrelevant with access technology, except being GPRS (General Packet Radio Service, GPRS), WLAN (Wireless Local Area Network, WLAN (wireless local area network)) grouping exchange (PacketSwitched such as, abbreviation PS) access network provides outside the business, can also be GSM (GlobalSystem for Mobile communications, global system for mobile communications), UMTS mobile cellular networks such as (Universal Mobile Telecommunications System, unified mobile communcations systems) provides professional.

Mobile cellular network such as GSM, UMTS adopts circuit-switched technology, is called circuit switching (Circuit Switched is called for short CS) territory, can provide basic speech business for the user, and based on the supplementary service of speech business.When IMS was inserted in the CS territory, it developed into a kind of access way, and business provides by IMS is unified fully, and this technology is called IMS centralized traffic (IMS Centralized Service is called for short ICS).

The IMS centralized traffic has the following advantages:

(1) IMS provides consistent business for access waies such as circuit commutative field, packet-switched domains, and network enabled merges.

(2) support the CS network to the evolution of IMS network.

(3) not only support to have ICS ability subscriber equipment, also support the existing subscriber equipment that does not possess the ICS ability, non-ICS subscriber equipment is also referred to as traditional subscriber equipment.

The present invention only pays close attention to non-ICS subscriber equipment.

Figure 1A right and wrong ICS user terminal inserts the Organization Chart of realizing IMS centralized control business by the CS territory, comprise following network element: user terminal (User Equipment, be called for short UE) 102A, adaption function (Local CS Access AdaptationFunction-network equivalent is inserted in the local circuit territory, be called for short L-CAAF-n) 104A, Visited Mobile Switching Center/VLR Visitor Location Register (Visited Mobile Switch Center/Visit LocationRegister, be called for short VMSC/VLR, VLR is used for storing the data of visitor, as information such as user's signing service data) 106A, home subscriber server (Home SubscriberServer, be called for short HSS) 108A, MGCF (Media Gateway ControlFunction, be called for short MGCF) 110A, media gateway (Media Gaeway, be called for short MGW) 112A, IMS circuit domain control function (IMS CS Control Function, be called for short ICCF) 114A, and CSCF (Call Session Control Function is called for short CSCF) 116A.

L-CAAF-n 104A is the adaption function of introducing for non-ICS subscriber equipment is linked into IMS, and it both can separate with VMSC/VLR 106A, also can unify.UE102A process L-CAAF-n 104A sets up 3 paths to the ICCF 114A in IMS territory: session control path, carrying control path and bearer path, wherein:

The session control path is carried on the CS territory, UE 102A adopts the CS control signaling of standard to insert L-CAAF-n 104A, the L-CAAF-n 104A information that wherein session control is relevant is by unstructured supplementary service data (the UnstructuredSupplementary SerVice Data on the circuit domain bearer path, be called for short USSD) through HSS 108A, insert ICCF114A.

Simultaneously, L-CAAF-n 104A will wherein control for information about the directly transparent VMSC/VLR 106A that is sent to the carrying of CS territory, be linked into IMS through MGCF 110A then, arrive ICCF 114A by CSCF 116A, form and carry the control path.

Bearer path is that UE 102A is linked into IMS by L-CAAF-n 104A, VMSC/VLR 106A and MGW 112A, and sets up medium with the remote user equipment of this session and be connected.

The IMS centralized traffic is utilized the interactive sessions control information between UE 102A and ICCF 114A of session control path, and sets up and the control media bearer by carrying control path, and ICCF 114A serves as the IMS user agent, replaces subscriber equipment to insert IMS.

Among Figure 1A, UE 102A need transmit session control signaling by L-CAAF-n 104A, VMSC/VLR106A, ICCF 114A, need simultaneously to transmit bearer control signalling by L-CAAF-n104A, VMSC/VLR 106A, MGCF 110A, CSCF 116A, ICCF 114A, logical ne is more like this, can merge the framework that Figure 1A is reduced to Figure 1B by network element.

Figure 1B is the IMS centralized control service application scene of simplification of prior art and the schematic diagram of session path.Shown in Figure 1B, by strengthening the VMSC/VLR106A among Figure 1A, merging such as user agent function with L-CAAF-n 104A, VMSC/VLR 106A, ICCF 114A, form a new logical ne EMSC (Enhanced MobileSwitch Center, mobile switching centre strengthens entity) 104B.UE 102B adopts the CS control signaling of standard to insert EMSC 104B, and EMSC 104B adopts session initiation protocol SIP, and session carrying and session control signaling are inserted CSCF 116B.Bearer path is that UE102B is linked into IMS by MGW 112B, and sets up medium with the remote user equipment of this session and be connected.DTF (Domain Transfer Functionality, territory transfer function entity) 114B is responsible for user's CS territory, the switching in IMS territory, and TAS (Telecom ApplicationService, telecommunication application server) 118B is responsible for the realization of user's supplementary service.

In the CS territory, CS user need regularly initiate the position and upgrade, this is because CS user maintains close ties with between travelling carriage and the network in order to keep, and allows network in time grasp mobile station state and position, and the network requirement travelling carriage is initiated the periodic location update request to network at regular intervals.Be to notify the mobile station position update cycle by system by broadcast mode cycle time, forces travelling carriage according to sending the period position update request from the trend network this cycle time.

At network side, need in the L-CAAF-n in the CS territory and VMSC/VLR or EMSC, also be set with the CS position renewing timer, when the mobile subscriber initiates position updating request, L-CAAF-n and VMSC/VLR or the EMSC CS position renewing timer of just resetting, if timer overflows, illustrate that the user may shut down or out of reach, then L-CAAF-n and VMSC/VLR or EMSC carry out " user's separation " (CS Detach) operation in the CS territory.

In addition, the IMS territory has stipulated that also the employing IMS registration timeout time judges whether the user is nullified.When the IMS terminal use initiates to register, carried the registration timeout time in the registration message.After S-CSCF receives register requirement, according to local policy is set the registration timeout time, this time can be less than or equal to the registration timeout time of carrying in user's register requirement, returns to the IMS terminal use then.The user must need to carry out the heavy registration process of IMS before IMS registration timeout timer expiry.If overtime timer overflows, then the IMS network is carried out overtime logout flow path.

In IMS, the IMS subscriber equipment must first be registered in IMS when using professional that IMS provides.When the user does not use network,, need in IMS, nullify as user's shutdown.For non-ICS subscriber equipment, it sees another patent " the non-ICS user's registration and the method for nullifying in the IMS centralized control business " in IMS registration and the flow process of nullifying, and replaces it to carry out IMS registration/heavily registration and log off procedure by L-CAAF-n.Replace the user briefly to describe to L-CAAF-n or EMSC below in registration of IMS territory and logout flow path.

As shown in Figure 2, non-ICS user is implemented in IMS registration/weight registration process and may further comprise the steps:

Step S202, non-ICS user initiates the periodic location update request to L-CAAF-n or EMSC, and L-CAAF-n and VMSC/VLR or EMSC carry out the CS territory user position update flow process of standard.

Step S204, VMSC/VLR or EMSC change to " user adheres to " with the CS User Status, and after CS user's loopback user position update success acknowledge message, CS user initiates register requirement by L-CAAF-n or EMSC to the IMS territory, carries out the Standard User register flow path in IMS territory.

Step S206, the S-CSCF in IMS territory carries out user registration process, and notice HSS user is registered, after HSS upgrades user registration state, S-CSCF notice L-CAAF-n or EMSC user registration success.

As shown in Figure 3, non-ICS user realizes that at IMS the process of nullifying may further comprise the steps:

Step S302, non-ICS user initiates user's detach request to L-CAAF-n or EMSC, and L-CAAF-n and VMSC/VLR or EMSC carry out CS territory user's separation process of standard.

After step S304, VMSC/VLR changed to " user separates " with the CS User Status, CS user initiated de-registration request by L-CAAF-n or EMSC to the IMS territory, carries out the user log off flow process in IMS territory.

Step S306, the S-CSCF in IMS territory carries out user log off to be handled, and notice HSS user is canceled, after HSS upgrades the user log off state, S-CSCF notice L-CAAF-n or the success of EMSC user log off, L-CAAF-n or EMSC separate acknowledge message to CS user's loopback user.

Present problem is, the IMS registration timer time that is provided with among the CS position renewing timer time that L-CAAF-n and VMSC/VLR or EMSC set, the S-CSCF may be inconsistent, realizes in IMS centralized control business that therefore there is serious problem in non-ICS user at the heavy login mechanism of IMS.Such as, under the IMS registration timer time situation that the CS position renewing timer time of setting in L-CAAF-n and VMSC/VLR or EMSC is provided with in greater than S-CSCF, CS territory position renewing timer is not overtime, CS user also is in state of activation, but, just can not trigger the heavy register flow path of user in the IMS territory because of not triggering the user position update flow process yet.And the registration timeout timer time that actual S-CSCF is provided with is overtime, and the user that it can will also be in state of activation nullifies in the IMS territory, causes non-ICS user to call out or conversation failure in the IMS territory, can't realize the IMS business.

If under the IMS registration timer time situation that the CS position renewing timer time of setting in L-CAAF-n and VMSC/VLR or EMSC is provided with in less than S-CSCF, when the user log off mode adopts the timer mode, so the CS position renewing timer time overtime after, in the CS territory CS user has been carried out user's lock out operation, CS user will place " user's separation " state.But not overtime because of the IMS registration timer, the user still keeps login state in the IMS territory, causes the User Status in CS territory and IMS territory inconsistent, and subsequent user all can't realize at the registration in IMS territory and session service etc.

Therefore need provide a kind of mechanism, both sides' time-out time can be consulted in assurance CS territory and IMS territory when the user registers.This mechanism need be registered the user/weigh in the registration process and realize.

S-CSCF will include the registration of IMS registration timeout time or ICCF is given in the sip message loopback of heavily succeeding in registration, and ICCF preserves this time-out time and starts the registration timeout timer.Simultaneously ICCF uses USSD on session control path, CS territory, will carry the registration of IMS registration timeout time or L-CAAF-n is given in the message loopback of heavily succeeding in registration.L-CAAF-n stores the IMS registration timeout time.Or S-CSCF will include the registration of IMS registration timeout time or the sip message that heavily succeeds in registration sends to EMSC, and EMSC stores the IMS registration timeout time.

Fig. 5 A is in the IMS centralized control business of the present invention, and non-ICS user realizes the flow chart that time-out time is consulted in the IMS registration process.CS user is in IMS registration or heavy registration process, embodiment that the registration timeout time consults is carried out as shown in Figure 5 in CS territory and IMS territory, it has described L-CAAF-n replaced C S user when the IMS territory is initiated registration or heavily registered, update time is issued S-CSCF in the CS position, S-CSCF resets IMS registration timeout timer time according to local policy, and gives ICCF and L-CAAF-n with the loopback of registration timeout time.Concrete steps are as follows:

Step S502A, CS user initiate CS user to L-CAAF-n and adhere to request or position updating request, and L-CAAF-n and VMSC/VLR carry out user position update and handle, and CS user upgrades successfully in position, CS territory, and User Status is " user adheres to " among the VLR at this moment.Position of the every initiation of CS user is upgraded, L-CAAF-n and the VMSC/VLR CS position renewing timer of need resetting.If L-CAAF-n and VMSC/VLR are at the unification of CS territory, the shared CS position renewing timer of L-CAAF-n and VMSC/VLR.

Step S504A, when CS user after position, CS territory is upgraded successfully, L-CAAF-n replaced C S user initiates in the registration in IMS territory or heavily registration.L-CAAF-n is on session control path, CS territory, use USSD that HSS is issued in user's registration or heavy login request message, HSS uses USSD that ICCF is issued in user's registration or heavy login request message, carries the CS position renewing timer time in registration or the heavy login request message.

Step S506A, ICCF adopt IMS standards registration flow process as the user agent in IMS territory, initiate SIP registration or heavy login request message to I-CSCF, comprise the CS position renewing timer time in SIP registration or the heavy registration message.

Step S508A, I-CSCF initiates user-authorization-request to HSS, and HSS judges whether the user is registered, sends the user-authorization-answer response to I-CSCF then, returns the S-CSCF address of having distributed.

Step S510A, I-CSCF sends SIP registration or heavy login request message according to the S-CSCF address to S-CSCF, comprises the CS position renewing timer time in registration or the heavy registration message.

Step S512A, S-CSCF judges it is registration or heavily registration according to user profile, and reset the registration timeout timer according to CS position renewing timer time and the local policy in registration or the heavy registration message, if S-CSCF finds that this request is an ICCF replaced C S Client-initiated register requirement, then adopt CS position update time as the IMS registration timeout time, guarantee CS territory and the consistency of IMS territory timer expiry time.S-CSCF initiates the server-assignment request to HSS, HSS stores this user's S-CSCF address, if it is " registered " state with user data update then that the user registers for the first time, HSS initiates the server-assignment response to S-CSCF then, and information such as user contracting data are issued S-CSCF.

When configuring registration timer after the time, S-CSCF starts this timer, carries out the overtime cancellation of user when this timer expiry.This timer of when the user heavily succeeds in registration once more, resetting.

Step S514A, S-CSCF issues professional controlling platform with user's registration or heavy registration message, and professional controlling platform is carried out user's registration or is heavily registered professional control flow.

Step S516A, S-CSCF comprises the IMS registration timeout time that S-CSCF sets to the sip message that I-CSCF initiates 200 OK registration or heavily succeeds in registration in the message, and the sip message that I-CSCF will register or heavily succeed in registration is issued ICCF.ICCF need preserve this time-out time and start the registration timeout timer, carries out the overtime cancellation of user when this timer expiry.When receiving user's response this timer of the time resetting that heavily succeeds in registration once more.

Step S518A, ICCF use USSD that the user's registration or the message that heavily succeeds in registration are issued L-CAAF-n by HSS on session control path, CS territory, carry the IMS registration timeout time that S-CSCF sets in the message, and L-CAAF-n stores the IMS registration timeout time.

Fig. 5 B is in the IMS centralized control business of the present invention, and non-ICS user realizes another embodiment flow chart that time-out time is consulted in the IMS registration process.CS user is in IMS registration or heavy registration process, EMSC replaced C S user initiates registration to the IMS territory, and S-CSCF is issued update time in the CS position, and S-CSCF resets IMS registration timeout timer time according to local policy, and give EMSC with the loopback of registration timeout time, concrete steps are as follows:

Step S502B-S508B, CS user do not register in CS territory and IMS, and CS user initiates CS user to EMSC and adheres to request, and EMSC carries out user position update and handles, and carries out subscription authentication and user data insertion process.CS user after position, CS territory is upgraded successfully, EMSC replacement CS position renewing timer, and to CS user answer success response message.

Step S510B, when CS user after position, CS territory is upgraded successfully, EMSC replaced C S user initiates the registration in the IMS territory.EMSC uses SIP that user's login request message is issued I-CSCF, carries the CS position renewing timer time in registration or the heavy login request message.

Step S512B, I-CSCF initiates user-authorization-request to HSS, and HSS judges whether the user is registered, sends the user-authorization-answer response to I-CSCF then, returns the S-CSCF address of having distributed.

Step S514B, I-CSCF sends the SIP login request message according to the S-CSCF address to S-CSCF, has carried the CS position renewing timer time in the registration message.

Step S516B, S-CSCF is according to CS position update time in the registration message and local policy resetting IMS registration timeout timer, if S-CSCF finds that this request is an EMSC replaced C S Client-initiated register requirement, then adopt CS position update time as the IMS registration timeout time, guarantee CS territory and the consistency of IMS territory timer expiry time.

Step S518B, S-CSCF initiates the server-assignment request to HSS, HSS stores this user's S-CSCF address, if it is " registered " state with user data update then that the user registers for the first time, HSS initiates the server-assignment response to S-CSCF then, and information such as user contracting data are issued S-CSCF.When configuring registration timer after the time, S-CSCF starts this timer, carries out the overtime cancellation of user when this timer expiry.This timer of when the user heavily succeeds in registration once more, resetting.

Step S520B, S-CSCF issues professional controlling platform with user's registration or heavy registration message, and professional controlling platform is carried out user's registration or is heavily registered professional control flow.

Step S522B, S-CSCF comprises the IMS registration timeout time that S-CSCF sets to the sip message that I-CSCF initiates 200 OK registration or heavily succeeds in registration in the message, and the sip message that I-CSCF will register or heavily succeed in registration is issued EMSC.EMSC stores the IMS registration timeout time.

The CS user that Fig. 5 B describes is equally applicable to the heavy register flow path of CS user at IMS at the IMS register flow path.

So far, CS user is in the flow process that the IMS territory is registered or heavily registered, L-CAAF-n or EMSC and S-CSCF have successfully carried out the negotiation of registration timeout time, L-CAAF-n or EMSC have issued S-CSCF update time with the CS position, S-CSCF has reset the IMS registration timeout time update time according to local policy and CS position, and given ICCF and L-CAAF-n or EMSC with the IMS registration timeout time loopback that resets, finished the timer expiry time negotiation mechanism in CS territory and IMS territory.

The described method of the embodiment of the invention described non-ICS user by CS territory access situation under in IMS territory registration or when heavily registering, L-CAAF-n or EMSC issue the CS position update time in CS territory, the S-CSCF in IMS territory resets the IMS registration timeout time update time according to local policy and CS position, the IMS registration timeout time can be set in strategy and adopt CS position update time, guarantee CS territory and the consistency of IMS overtime timer time, ensure that CS user is in the registration in IMS territory and the consistency of exit state and CS territory User Status.

Flow chart according to a kind of cancellation of the present invention and customer separating method, as shown in Figure 6A, when CS position update time is consistent with IMS position update time, adopts the timer expiry mode that non-ICS user is nullified and carry out in the CS territory flow process that the user separates at IMS and may further comprise the steps:

Step S602A, because the user does not have activity, the CS position renewing timer is overtime, and L-CAAF-n or VMSC/VLR carry out user's lock out operation, and User Status is updated to " user's separation ", and L-CAAF-n nullifies the user.

Step S604A, if ICCF exists, it is overtime that while ICCF detects its registration timer, ICCF carries out user log off.

Step S606A, it is overtime that while S-CSCF detects the IMS registration timer, and S-CSCF carries out user log off, S-CSCF notice HSS user log off, HSS change user log off state, and to S-CSCF hair family cancellation success message.

Wherein, step S602A independently carries out to step S606A.

Flow chart according to another kind of cancellation of the present invention and customer separating method, shown in Fig. 6 B, when CS position update time is consistent with IMS position update time, adopts the timer expiry mode that non-ICS user is nullified and carry out in the CS territory flow process that the user separates at IMS and may further comprise the steps:

Step S602B, because the user does not have activity, the CS position renewing timer is overtime, and EMSC carries out user's lock out operation, and User Status is updated to " user's separation ", and L-CAAF-n nullifies the user.

Step S604B, if ICCF exists, it is overtime that while ICCF detects its registration timer, ICCF carries out user log off.

Step S606B, it is overtime that while S-CSCF detects the IMS registration timer, and S-CSCF carries out user log off, S-CSCF notice HSS user log off, HSS change user log off state, and to S-CSCF hair family cancellation success message.

Wherein, step S602B independently carries out to step S606B.

Adopt method provided by the invention, when non-ICS user inserts by the CS territory, L-CAAF-n/VMSC, ICCF, S-CSCF, EMSC can initiate to nullify to the user simultaneously, guarantee that User Status is in the IMS territory and the consistency in CS territory.

User's overtime cancellation realization flow was as follows when time-out time was consistent:

Under CS position update time prerequisite consistent with the IMS registration timeout time, user's starting logout flow path of in background technology, describing, the mode that can also adopt timer to nullify.L-CAAF-n/VMSC, ICCF, S-CSCF, EMSC adopt timer expiry to nullify.

Fig. 7 A is in the IMS centralized control business of the present invention, and non-ICS user realizes the flow chart of the embodiment that timer is nullified.Shown in Fig. 7 A, when having described non-ICS subscriber equipment inertia according to logout flow path, the L-CAAF-n/VMSC/VLR position renewing timer is overtime, and L-CAAF-n/VMSC/VLR initiates CS user and separates, and VLR changes to user data " user's separation " state.Equally, ICCF the S-CSCF registration timer overtime after, ICCF carries out user log off to be handled, S-CSCF also carries out user log off to be handled, and notice HSS user log off, concrete steps are as follows:

Step S702A, CS user does not initiate position updating request to L-CAAF-n for a long time, the time that this moment, the CS position renewing timer among the L-CAAF-n/VMSC was set is overtime, and L-CAAF-n/VMSC/VLR carries out CS user's lock out operation, and VLR is changed to user data " user's separation " state.

Step S704A, the time that the user's registration timeout timer in ICCF is set is simultaneously overtime, and ICCF nullifies processing to the user.

Step S706A, the time that the user's registration timeout timer in S-CSCF is set is simultaneously also overtime, and S-CSCF nullifies processing to the user.

Step S708A, S-CSCF issues professional controlling platform with user log off message, and professional controlling platform adopts the IMS normal process, carries out the user log off service control function.

Step S710A, S-CSCF initiates the server-assignment request to HSS, and HSS changes to User Status " cancellation " state, and HSS initiates the server-assignment response to S-CSCF, and notice S-CSCF user is canceled.

Above step S702A, S704A, S706A are the independent cancellation step of carrying out.

Shown in Fig. 7 B, when having described non-ICS subscriber equipment inertia according to logout flow path, the CS position renewing timer among the EMSC is overtime, and EMSC initiates CS user's lock out operation.Equally, after the S-CSCF registration timer was overtime, S-CSCF also carries out user log off to be handled, and notice HSS user log off, and concrete steps are as follows:

Step S702B, CS user for a long time not initiate position updating request to EMSC, and the time that the CS position renewing timer among this moment EMSC is set is overtime, and EMSC carries out CS user's lock out operation, user data is changed to " user's separation " state.

Step S704B, the time that the user's registration timeout timer in S-CSCF is set is simultaneously also overtime, and S-CSCF nullifies processing to the user.

Step S706B, S-CSCF issues professional controlling platform with user log off message, and professional controlling platform adopts the IMS normal process, carries out the user log off service control function.

Step S708B, S-CSCF initiates the server-assignment request to HSS, and HSS changes to User Status " cancellation " state, and HSS initiates the server-assignment response to S-CSCF, and notice S-CSCF user is canceled.

Above step S702B, S704B are the independent cancellation step of carrying out.

So far, the user nullifies successfully in the IMS territory, in the CS territory user is placed " user's separation " state simultaneously.

The invention provides in a kind of IMS centralized control business the heavily implementation method of registration and unregistration, overcome the inconsistent problem that may cause of CS position renewing timer time and IMS registration timeout time.

Find after deliberation, when the CS position renewing timer time greater than IMS registration timer time situation under, can be before the IMS registration timeout time arrives by L-CAAF-n or ICCF, EMSC, automatically replace non-ICS subscriber equipment to carry out the IMS registration process, reach the purpose that keeps user IMS login state.

Initiate CS user's separation or L-CAAF-n, EMSC when detecting non-ICS subscriber equipment inertia when non-ICS subscriber equipment in addition, L-CAAF-n initiatively sends de-registration request message to ICCF, or EMSC initiatively initiates to nullify to the IMS territory, thereby guarantees that CS user correctly nullifies at IMS.This method can solve the problem that the CS position renewing timer time caused less than the IMS registration timer time that is provided with among the S-CSCF, and this cancellation method also can be used under the situation of CS position renewing timer time more than or equal to the IMS registration timer time simultaneously.

In IMS centralized control business, CS user upgrades and under the registered situation in IMS territory, realizes the implementation method of the heavy registration process of IMS in successful position in the CS territory.

Wherein, in IMS centralized control business, CS user upgrades and is registered in the IMS territory in successful position in the CS territory, and non-ICS user is the implementation method of registration and unregistration heavily, wherein, L-CAAF-n, EMSC or ICCF replace subscriber equipment execution IMS heavily to register according to IMS registration timeout time cycle property ground.

Wherein, the IMS registration timeout time is that L-CAAF-n, EMSC or ICCF obtain the IMS registration timeout time from IMS registration response.

L-CAAF-n, EMSC or ICCF carried out IMS and heavily register before the registration timeout timer expiry.If carry out heavy registration process by ICCF, when L-CAAF-n receives the CS position updating request, can send the heavy register requirement of IMS to ICCF by CS session control path, perhaps do not send.After ICCF receives the heavy register requirement of L-CAAF-n, can send the heavy register requirement of SIP, perhaps not send to I/S-CSCF.If carry out heavy registration process by L-CAAF-n or EMSC, when L-CAAF-n or EMSC receive the user position update request, can send the heavy register requirement of IMS to S-CSCF, perhaps do not send.If the CS position renewing timer is overtime among L-CAAF-n or the EMSC, L-CAAF-n or EMSC judge that the user is inactive, or arrive non-ICS user's CS territory detach request, and then L-CAAF-n or EMSC send the user log off request message to the IMS territory.

Fig. 8 inserts adaption function entity or IMS circuit controlled function entity or mobile switching centre's entity according to local circuit of the present invention territory to replace subscriber equipment to carry out the flow chart of the heavy process registration of IMS.They replace subscriber equipment execution IMS heavily to register according to IMS registration timeout time cycle property ground, comprise the steps:

Step S802, L-CAAF-n or ICCF or EMSC be according to the IMS registration timeout time, starts heavy registration timer, sends heavy register requirement to call session control function module in the IMS registration timeout time before overtime.

Wherein, the time-out time of the heavy registration timer of IMS guaranteed to send heavy register requirement to call session control function module before the IMS registration timeout time less than the IMS registration timeout time.

Step S804, call session control function module CSCF carry out the heavy registration process of IMS, upgrade subscriber equipment IMS login state.

Step S806, call session control function module returns the response of heavily succeeding in registration to L-CAAF-n or ICCF or EMSC.。

Step S808, L-CAAF-n or ICCF or EMSC reset and weigh registration timer, return execution in step S802.

Fig. 9 A replaces subscriber equipment to carry out the flow chart of the heavy process registration of IMS according to L-CAAF-n of the present invention or EMSC according to IMS registration timeout time cycle property ground.

Wherein, L-CAAF-n heavily registers according to IMS registration timeout time cycle property ground replacement subscriber equipment execution IMS and comprises the steps:

Step S902A, L-CAAF-n start heavy registration timer according to the IMS registration timeout time, by CS session control path, use USSD to send heavy register requirement to ICCF before the IMS registration timeout time.

Wherein, the time-out time of the heavy registration timer of IMS guaranteed to send heavy register requirement to call session control function module before the IMS registration timeout time less than the IMS registration timeout time.

Step S904A, ICCF sends the heavy register requirement of SIP to call session control function module CSCF.Call session control function module is carried out IMS and is heavily registered service logic, upgrades subscriber equipment IMS login state.Call session control function module returns the response of heavily succeeding in registration to ICCF.ICCF uses USSD to send the response of heavily succeeding in registration to L-CAAF-n by CS session control path.

Step S906A, L-CAAF-n replacement registration timeout timer returns execution in step S902A.

L-CAAF-n is after the CS position renewing timer is overtime, and replace subscriber equipment to carry out log off procedure and may further comprise the steps: L-CAAF-n uses USSD that the user log off request message is issued ICCF; ICCF is to the sip message of I/S-CSCF transmission user log off, and S-CSCF carries out user log off and handles, and notice HSS user log off; S-CSCF returns user SIP to ICCF and nullifies success response message, and ICCF uses USSD to L-CAAF-n loopback user log off success message on the session path of CS territory.

Fig. 9 B is that EMSC replaces subscriber equipment to carry out the flow chart of the heavy process registration of IMS according to IMS registration timeout time cycle property ground according to the present invention, comprises the steps:

Step S902B, EMSC start heavy registration timer according to the IMS registration timeout time, by session and carrying control path, send the heavy register requirement of SIP to call session control function module CSCF before the IMS registration timeout time.

Wherein, the time-out time of the heavy registration timer of IMS guaranteed to send heavy register requirement to call session control function module before the IMS registration timeout time less than the IMS registration timeout time.

Step S904B, call session control function module is carried out IMS and is heavily registered service logic, upgrades subscriber equipment IMS login state, if change update time of CS position need be consulted the IMS registration timeout time again.Call session control function module returns the response of heavily succeeding in registration to EMSC.

Step S906B, EMSC determine whether the IMS registration timeout time change, if change is just preserved and adopted the new IMS registration timeout time.The registration timeout timer of resetting then returns execution in step S902B.

EMSC is after the CS position renewing timer is overtime, and replace subscriber equipment to carry out log off procedure and may further comprise the steps: EMSC is to the sip message of I/S-CSCF transmission user log off, and S-CSCF carries out user log off and handles, and notice HSS user log off; S-CSCF returns user SIP to EMSC and nullifies success response message.

Adopt method provided by the invention, when non-ICS user inserts by the CS territory, if the CS position is greater than the IMS registration timeout time update time, can be implemented in and carry out the user in the IMS registration timeout time and heavily register, reach in overtime back update time, CS position and carry out user log off, guaranteed the consistency of CS user in CS territory and IMS territory User Status in the IMS territory.

When time-out time was inconsistent, CS position update time was greater than the heavily registration of IMS hour of log-on and the realization flow of overtime cancellation.

When the S-CSCF in IMS territory does not accept CS position update time according to local policy, L-CAAF-n or EMSC receive the IMS registration timeout time, and after comparing update time with the CS position, a kind of situation may appear be CS position update time greater than the IMS registration timeout time, the heavily registration when needing settling time inconsistent and the problem of overtime cancellation.

In the described method of present embodiment, described non-ICS user and carried out location update operations in the CS territory, and successfully registered in the IMS territory.S-CSCF with IMS registration timeout time announcement L-CAAF-n and ICCF or EMSC.Need to solve CS position update time at L-CAAF-n or EMSC greater than IMS registration timeout time situation under, CS user heavily registers in the IMS territory before IMS registration timeout timer expiry, after avoiding IMS registration timeout timer expiry, at the automatic logging off users in IMS territory, make the CS user who still is in state of activation can't carry out the IMS session service.

Do not need simultaneously to solve when CS user does not initiate user position update for a long time yet and operate, the problem that CS user nullifies in the IMS territory when having exceeded the time of CS position renewing timer setting blanking time.This moment, user's lock out operation need be carried out in the CS territory, and User Status is updated to " user separates ".So just require in the IMS territory to initiate user log off earlier, nullify inactive CS user, the consistency of the User Status in assurance IMS territory and the User Status in CS territory.

In the time that IMS registration timeout timer is set, automatically the embodiment that initiates heavily registration by L-CAAF-n replaced C S user as shown in figure 10, it has described CS position update time greater than under the IMS registration timeout time situation, in L-CAAF-n, set a heavy registration timer in addition, the setting of time is less than the IMS registration timeout time, registration timer is overtime when weighing, the heavy register flow path of L-CAAF-n will be triggered, this moment, L-CAAF-n replaced C S user heavily registered in the IMS territory, kept the login state of CS user in the IMS territory.Concrete steps are as follows:

Step S1002A, CS user upgrade successfully in position, CS territory, and succeed in registration in the IMS territory.The S-CSCF in IMS territory has issued L-CAAF-n with the IMS registration timeout time in the registration response, L-CAAF-n judges that the IMS registration timeout time is less than CS position update time, L-CAAF-n is at heavy registration timer of inner setting, and time-out time is less than the IMS registration timeout time.While L-CAAF-n is replacement CS position renewing timer when the user position update success, and S-CAAF is replacement IMS registration timeout timer when user registration success.

Step S1004A, overtime when the heavy registration timer of L-CAAF-n inner setting, triggered the heavy register flow path of L-CAAF-n, L-CAAF-n is with regard to the heavy register flow path of replaced C S user initiation in the IMS territory.L-CAAF-n uses USSD that the heavy login request message of user is issued HSS on session control path, CS territory, and HSS uses USSD that the heavy login request message of user is issued ICCF.

Step S1006A, when CS user initiates user position update, because of having replaced the user, L-CAAF-n carries out the periodicity emphasis registration in the IMS territory, this moment, L-CAAF-n can send the heavy register requirement of user to ICCF, carry out the heavy registration process of IMS one time, can not send yet, do not influence the user registration state of IMS.

Step S1008A, ICCF adopt IMS standard weight register flow path as the user agent in IMS territory, and the sip message that the user heavily registers is issued I-CSCF.

Step S1010A, I-CSCF initiates user-authorization-request to HSS, and HSS judges whether the user is registered, sends the user-authorization-answer response to I-CSCF then, returns the S-CSCF address of having distributed.

Step S1012A, I-CSCF sends the sip message that the user heavily registers according to the S-CSCF address to S-CSCF.

Step S1014A, S-CSCF judges it is heavily to register according to user profile, S-CSCF replacement IMS registration timeout timer, and to the request of HSS initiation server-assignment, HSS stores this user's S-CSCF address, initiate the server-assignment response to S-CSCF, information such as user contracting data are issued S-CSCF.

Step S1016A, S-CSCF issues professional controlling platform with the heavy registration message of user, and professional controlling platform is carried out the user and is heavily registered professional control flow.

Step S1018A, S-CSCF sends the sip message that 200 OK heavily succeed in registration to I-CSCF, and I-CSCF issues ICCF with the sip message that heavily succeeds in registration.

Step S1020A, ICCF use USSD that user's message that heavily succeeds in registration is issued L-CAAF-n by HSS, the heavy registration timer of L-CAAF-n replacement inner setting on session control path, CS territory.

When CS user normally carried out user position update, L-CAAF-n carried out the normal flow heavily registered at IMS.L-CAAF-n receives after the message that heavily succeeds in registration in IMS territory in this case, the heavy registration timer of the inner setting of also need resetting.

In the time that IMS registration timeout timer is set, automatically initiate the embodiment of heavily registration shown in Figure 10 B by EMSC replaced C S user, it has described CS position update time greater than under the IMS registration timeout time situation, in EMSC, set a heavy registration timer in addition, the setting of time is less than the IMS registration timeout time, registration timer is overtime when weighing, the heavy register flow path of EMSC will be triggered, this moment, EMSC replaced C S user heavily registered in the IMS territory, keep the login state of CS user in the IMS territory, concrete steps are as follows:

Step S1002B, CS user upgrade successfully in position, CS territory, and succeed in registration in the IMS territory.The S-CSCF in IMS territory has issued EMSC with the IMS registration timeout time in registration response, EMSC judges the IMS registration timeout time less than CS position update time, and EMSC is at heavy registration timer of inner setting, and time-out time is less than the IMS registration timeout time.While EMSC is replacement CS position renewing timer when the user position update success, and S-CSCF is replacement IMS registration timeout timer when user registration success.

Step S1004B-S1006B, when the heavy registration timer of EMSC inner setting overtime, triggered the heavy register flow path of EMSC, EMSC replaced C S user initiates the heavy register flow path in the IMS territory, the sip message that the user heavily registers is issued I-CSCF, if there is change the CS position update time, need carry CS position update time after changing.

When CS user initiates user position update, because of having replaced the user, EMSC carries out the periodicity emphasis registration in the IMS territory, and this moment, EMSC can carry out the heavy registration process of IMS one time, also can not carry out, and did not influence the user registration state of IMS.

Step S1008B, I-CSCF initiates user-authorization-request to HSS, and HSS judges whether the user is registered, sends the user-authorization-answer response to I-CSCF then, returns the S-CSCF address of having distributed.

Step S1010B, I-CSCF sends the sip message that the user heavily registers according to the S-CSCF address to S-CSCF.

Step S1012B-S1014B, S-CSCF judges it is heavily to register according to user profile, S-CSCF need judge whether the CS position changes update time, if there is change to change again the IMS registration timeout time.The IMS registration timeout timer of resetting then, and initiate the server-assignment request to HSS, HSS stores this user's S-CSCF address, initiates the server-assignment response to S-CSCF, and information such as user contracting data are issued S-CSCF.

Step S1016B, S-CSCF issues professional controlling platform with the heavy registration message of user, and professional controlling platform is carried out the user and is heavily registered professional control flow.

Step S1018B, S-CSCF sends the sip message that 200 OK heavily succeed in registration to I-CSCF, and I-CSCF issues EMSC with the sip message that heavily succeeds in registration, the heavy registration timer of EMSC replacement inner setting.

When CS user normally carried out user position update, EMSC carried out the normal flow heavily registered at IMS.EMSC receives after the message that heavily succeeds in registration in IMS territory in this case, the heavy registration timer of the inner setting of also need resetting.

So far, L-CAAF-n or EMSC replaced C S user heavily succeed in registration in the IMS territory, avoid IMS registration timeout timer expiry after S-CSCF the user is nullified, the problem that makes the user who still is in state of activation in the CS territory can't carry out the IMS session takes place.

In the time that IMS registration timeout timer is set, automatically the embodiment that initiates heavily registration by ICCF replaced C S user as shown in figure 11, it has described CS position update time greater than under the IMS registration timeout time situation, in ICCF, set a heavy registration timer in addition, the setting of time is less than the IMS registration timeout time, and is overtime when heavy registration timer, will trigger the heavy register flow path of ICCF, this moment, ICCF replaced C S user heavily registered in the IMS territory, kept the login state of CS user in the IMS territory.Concrete steps are as follows:

Step S1102, CS user upgrade successfully in position, CS territory, and succeed in registration in the IMS territory.L-CAAF-n has issued ICCF with the CS position update time when registration, the S-CSCF in IMS territory has also issued ICCF with the IMS registration timeout time in the registration response.ICCF judges the IMS registration timeout time less than CS position update time, and ICCF is at heavy registration timer of inner setting, and time-out time is less than the IMS registration timeout time.While S-CAAF replacement IMS registration timeout timer when user registration success, ICCF start heavy registration timer when user registration success.

Step S1104, overtime when the heavy registration timer of ICCF inner setting, triggered the heavy register flow path of ICCF, ICCF is with regard to the heavy register flow path of replaced C S user initiation in the IMS territory.ICCF adopts IMS standard weight register flow path as the user agent in IMS territory, and the sip message that the user heavily registers is issued I-CSCF.

Step S1106 when CS user initiates user position update, carries out the periodicity emphasis registration because of ICCF has replaced the user in the IMS territory, this moment, L-CAAF-n can replaced C S user initiate the heavy register requirement of user to ICCF, also can not send.ICCF receives the heavy login request message of L-CAAF-n, can carry out the heavy registration process of IMS one time, also can not carry out, and does not influence the user registration state of IMS.

Step S1108, I-CSCF initiates user-authorization-request to HSS, and HSS judges whether the user is registered, sends the user-authorization-answer response to I-CSCF then, returns the S-CSCF address of having distributed.

Step S1110, I-CSCF sends the sip message that the user heavily registers according to the S-CSCF address to S-CSCF.

Step S1112, S-CSCF judges it is heavily to register according to user profile, S-CSCF replacement IMS registration timeout timer, and to the request of HSS initiation server-assignment, HSS stores this user's S-CSCF address, initiate the server-assignment response to S-CSCF, information such as user contracting data are issued S-CSCF.

Step S1114, S-CSCF issues professional controlling platform with the heavy registration message of user, and professional controlling platform is carried out the user and is heavily registered professional control flow.

Step S1116, S-CSCF sends the sip message that 200 OK heavily succeed in registration to I-CSCF, and I-CSCF issues ICCF with the sip message that heavily succeeds in registration, the heavy registration timer of ICCF replacement inner setting after the user heavily succeeds in registration.

So far, ICCF replaced C S user heavily succeeds in registration in the IMS territory, avoid IMS registration timeout timer expiry after S-CSCF the user is nullified, the problem that makes the user who still is in state of activation in the CS territory can't carry out the IMS session takes place.

When the IMS registration timeout time greater than CS position update time, L-CAAF-n or EMSC replace the user heavily to register in the IMS territory.When the user is in non-responsive state, it is not issued periodic position and upgrades, and causes the CS position of network side overtime update time, this moment need be in the CS territory and the IMS territory carry out overtime cancellation.Simultaneously when CS position update time less than the IMS registration timeout time, the overtime cancellation problem when at this moment also needing settling time inconsistent.

In the described method of the embodiment of the invention, when non-ICS user has carried out location update operations in the CS territory, and successfully register in the IMS territory, S-CSCF with IMS registration timeout time announcement L-CAAF-n or EMSC.When CS user does not initiate the user position update operation for a long time, exceeded the time that the CS position renewing timer is set blanking time, this moment CS position update time of L-CAAF-n or EMSC less than or greater than IMS registration timeout time situation under, L-CAAF-n in the CS territory or EMSC judge user's inertia, just initiate user log off in the IMS territory, nullify inactive CS user, and at CS territory execution user lock out operation, User Status is updated to " user separates " consistency of the User Status in assurance IMS territory and the User Status in CS territory.

After the CS position renewing timer is overtime, the embodiment that L-CAAF-n replaced C S user initiatively initiates at IMS territory logout flow path is shown in Figure 12 A, it has been described after the CS position renewing timer among L-CAAF-n and the VMSC/VLR is overtime, L-CAAF-n judges that the user is inactive, triggered the logout flow path of L-CAAF-n in the IMS territory, this moment, L-CAAF-n replaced C S user nullified in the IMS territory.L-CAAF-n and VMSC/VLR carry out user's lock out operation after nullifying successfully in the IMS territory in the CS territory, and concrete steps are as follows:

Step S1202A, CS user upgrade successfully in position, CS territory, and succeed in registration in the IMS territory.The S-CSCF in IMS territory has issued L-CAAF-n with the IMS registration timeout time in the registration response.L-CAAF-n is replacement CS position renewing timer when the user position update success, and S-CAAF is replacement IMS registration timeout timer when user registration success.

Step S1204A, L-CAAF-n carries out periodicity user for CS user at IMS at the overtime former generation of IMS registration timer and heavily registers, but CS user does not initiate periodically user position update for a long time in the CS territory, the CS position renewing timer that be provided with among L-CAAF-n and the VMSC/VLR this moment is overtime, and L-CAAF-n judges that the user is inactive.

Step S1206A, overtime when the CS position renewing timer, L-CAAF-n determines that the user is inactive, VMSC/VLR to the user before user's lock out operation is carried out in the CS territory, the replaced C S user of L-CAAF-n elder generation initiates the logout flow path in the IMS territory.L-CAAF-n uses USSD that the user log off request message is issued HSS on session control path, CS territory, and HSS uses USSD that the user log off request message is issued ICCF.

Step S1208A, when CS user initiates user's detach request, L-CAAF-n replace the user carry out the flow process of nullifying in the IMS territory therewith flow process be consistent.

Step S1210A, ICCF as the user agent, adopt IMS standards registration flow process in the IMS territory, and the sip message of user log off is issued I-CSCF.

I-CSCF initiates user-authorization-request to HSS, notice HSS user log off, and HSS sends the user-authorization-answer response to I-CSCF, and I-CSCF is issued in the S-CSCF address.

Step S1212A, I-CSCF issue S-CSCF according to the S-CSCF address with the sip message of user log off.

Step S1214A, S-CSCF issues professional controlling platform with user log off message, and professional controlling platform is carried out the professional control flow of corresponding user log off.

Step S1216A, S-CSCF initiates the server-assignment request to HSS, and HSS changes to User Status " cancellation " state, and HSS initiates the server-assignment response to S-CSCF, and notice S-CSCF user is canceled.

Step S1218A, the sip message that S-CSCF initiates 200 OK user log off successes to I-CSCF, I-CSCF will nullify successful sip message and issue ICCF, and ICCF carries out log off procedure after receiving and nullifying success response, and it is unregistered state that User Status is set.

Step S1220A, ICCF use USSD that the user is nullified success message in the IMS territory and issue L-CAAF-n by HSS on session control path, CS territory, and L-CAAF-n carries out log off procedure after receiving and nullifying success response, and it is unregistered state that User Status is set.

Step S1222A, receive that IMS nullifies success response after, L-CAAF and the user lock out operation of VMSC/VLR execution in the CS territory change to User Status " user separates " state in VLR.

After the CS position renewing timer is overtime, the embodiment that EMSC replaced C S user initiatively initiates at IMS territory logout flow path as shown in Figure 14B, it has been described after the CS position renewing timer among the EMSC is overtime, EMSC judges that the user is inactive, triggered the user log off flow process of EMSC to the IMS territory, this moment, EMSC replaced C S user nullified in the IMS territory.EMSC carries out user's lock out operation after nullifying successfully in the IMS territory in the CS territory, and concrete steps are as follows:

Step S1202B, CS user upgrade successfully in position, CS territory, and succeed in registration in the IMS territory.The S-CSCF in IMS territory has issued EMSC with the IMS registration timeout time in registration response, EMSC judges that the IMS registration timeout time is greater than CS position update time.

Step S1204B, CS user do not initiate periodically user position update for a long time in the CS territory, the CS position renewing timer that be provided with among the EMSC this moment is overtime, and EMSC judges that the user is inactive.

Step S1206B, after the CS position renewing timer was overtime, the user data deletion need be carried out to CS user in the CS territory.But because of the IMS registration timeout time greater than CS position update time, this moment, user log off can not initiated to the user in the IMS territory.Therefore for keeping the consistency of CS territory and IMS territory User Status, EMSC issues I-CSCF with regard to the logout flow path of replaced C S user initiation in the IMS territory with the sip message of user log off.

Step S1208B, I-CSCF initiates user-authorization-request to HSS, notice HSS user log off, HSS sends the user-authorization-answer response to I-CSCF, and I-CSCF is issued in the S-CSCF address.

Step S1210B, I-CSCF issue S-CSCF according to the S-CSCF address with the sip message of user log off.

Step S1212B, S-CSCF issues professional controlling platform with user log off message, and professional controlling platform is carried out the professional control flow of corresponding user log off.

Step S1214B, S-CSCF initiates the server-assignment request to HSS, and HSS changes to User Status " cancellation " state, and HSS initiates the server-assignment response to S-CSCF, and notice S-CSCF user is canceled.

Step S1216B, the sip message that S-CSCF initiates 200 OK user log off successes to I-CSCF, I-CSCF will nullify successful sip message and issue EMSC.

After step S1218B, EMSC receive and nullify success response, carry out log off procedure, User Status is set is " user's separation " state in the CS territory.

So far, carried out user's lock out operation in the CS territory during CS user's inertia, also nullify successfully in the IMS territory simultaneously, guaranteed User Status in the CS territory and the consistency in IMS territory, CS user need adhere to again in the CS territory and re-register just in the IMS territory and can carry out the IMS session.This logout flow path is applicable to that too CS user initiates user's detach request, and L-CAAF-n or EMSC replaced C S user nullify at IMS, and L-CAAF-n and VMSC/VLR or EMSC carry out user's lock out operation then.

The invention provides CS user in a kind of IMS centralized control business in the CS position implementation procedure that update time, nullified in the IMS territory overtime back.

Find after deliberation, when the CS position renewing timer time less than IMS registration timer time situation under, when L-CAAF-n or EMSC detect non-ICS subscriber equipment inertia, be that non-ICS subscriber equipment is not initiated user position update in the CS position renewing timer time-out time, L-CAAF-n or EMSC initiatively initiate user log off to the IMS territory, can solve the inconsistent problem that causes of the IMS registration timer time that is provided with among CS position renewing timer time and the S-CSCF like this, this cancellation method also is applicable to the situation of CS position renewing timer time more than or equal to IMS registration timer time-out time simultaneously, is applicable to that also CS user normally initiates the situation that the user separates.

In IMS centralized control business, CS user upgrades and is registered in the IMS territory in successful position in the CS territory, in the CS position method that update time, nullified in the IMS territory overtime back, wherein, when subscriber equipment not execution cycle property position renewal in update time in the CS position, L-CAAF-n or EMSC judge that the user is inactive, so L-CAAF-n or EMSC replaced C S user, S-CSCF to the IMS territory sends the user log off request message, carries out the user log off operation at IMS.

Wherein, when the user after successfully nullify in the IMS territory, VMSC/VLR or EMSC carry out user's lock out operation in the CS territory to the user, and the CS User Status is changed to " user separates " state.

Figure 13 is the flow chart according to cancellation method of the present invention.As shown in figure 13, this method may further comprise the steps:

Step S1302, L-CAAF-n or EMSC issue I-CSCF in the IMS territory with the user log off request message.

Step S1304, I-CSCF is transmitted to the S-CSCF that the user serves with de-registration request, and S-CSCF carries out user log off and handles, and notice HSS user log off.

Step S1306, then S-CSCF through I-CSCF to L-CAAF-n or EMSC loopback user log off success message.

Wherein, in step S1306, after L-CAAF-n or EMSC receive and nullify success response, carry out the user at CS territory log off procedure, it is unregistered state that User Status is set.

Adopt method provided by the invention, when non-ICS user inserts by the CS territory, carry out at IMS territory user log off in the IMS territory overtime back update time if the CS position, can be implemented in the CS position less than the IMS registration timeout time update time, has guaranteed the consistency of CS user in CS territory and IMS territory User Status.

So far, carried out user's lock out operation in the CS territory during CS user's inertia, also nullify successfully in the IMS territory simultaneously, guaranteed User Status in the CS territory and the consistency in IMS territory, CS user need adhere to again in the CS territory and re-register just in the IMS territory and can carry out the IMS session.This logout flow path is applicable to that too CS user initiates user's detach request, and L-CAAF-n or EMSC replaced C S user nullify at IMS, and L-CAAF-n and VMSC/VLR or EMSC carry out user's lock out operation then.

The present invention is in order to solve CS position update time and inconsistent problem of IMS registration timeout time, the present invention is in the registration or heavy register flow path of CS user in the IMS territory, carry CS position update time in registration that sends to the IMS territory by L-CAAF-n or EMSC or the heavy login request message, S-CSCF is according to CS position update time and local policy resetting the IMS registration timeout time, and give L-CAAF-n or EMSC with the time loopback of IMS registration timeout, finish the negotiations process of the registration timeout time in CS territory and IMS territory.Below embodiment is described in detail, but not as a limitation of the invention.
