When initiating to go to register for a certain input field under many registration scenarios, do not trigger the cancellation of corresponding implicitly registered set, the embodiment of the invention provides many register methods in a kind of IMS territory, comprises following content:
User agent's network element perception UE is in the attachment state information (with above) in CS territory, judge that this UE is after the CS territory is adhered to, the interim IMPU (T-IMPU), the interim IMPI (T-IMPI) that use IMSI to derive from, and carry heavy sign-on ID (sign 1) and register to IMS.When this UE initiates registration in the PS territory, carry the T-IMPU that IMSI derives from equally, T-IMPI, and heavy sign-on ID (sign 2) is registered to IMS.
Owing to carried different heavy sign-on IDs, so S-CSCF can come these two registration differences, preservation simultaneously has identical IMPU/IMPI and two parts of information of different heavy sign-on ID/Contact address; Rather than the Contact address of the registration in back override the Contact address that preservation is said in front registration, only preserve a piece of data.Simultaneously, S-CSCF after any one registration, can arrive and download implicitly registered set among the HSS in finishing above-mentioned two input fields, registers the IMPU that is associated automatically.All follow-up conversation request can use the IMPU that is associated to carry out.Like this, no matter be that the user is registered to IMS by the CS territory, still be registered to IMS by the PS territory, perhaps two are registered to IMS simultaneously, can be by the operation of identical IMPU initiation session, and be triggered on the AS according to the service trigger criteria of " registered " by S-CSCF and handle.
Existing S-CSCF not definition to implicitly registered set under many registration scenarios go the registration behavior, can go all relevant related IMPU of registered set to register immediately under the situation that any one registration that implicit registration is concentrated goes to register finding according to present definition S-CSCF.So even under the situation of having finished above-mentioned many registrations, the CS territory still is that the PS territory initiates to go to register all to cause all IMPU to go registration, the user will be the state of " unregistered " in IMS this moment.
So need redefine the behavior of S-CSCF: when S-CSCF receive from certain territory go register requirement the time, situation for many registrations, at first seek the log-on message of the different heavy sign-on ID that whether has identical IMPU/IMPI, if also have other registration, then do not trigger the cancellation of corresponding implicitly registered set, after having only all registrations of this IMPU/IMPI correspondence all to nullify, the just real cancellation that triggers corresponding implicitly registered set.
The embodiment of the invention also provides a kind of S-CSCF, and referring to shown in Figure 9, it comprises: the receiving element of Xiang Lianing, judging unit and cancellation unit successively.
Receiving element is used to receive the register requirement of going at UE that initiate in CS territory or PS territory.
Judging unit, be used for judge current have that a heavy sign-on ID and receiving element receive go IMPU that register requirement carries and IMPI at once, send logoff signal.
Nullify the unit, be used for when receiving the logoff signal that judging unit is sent, nullify the implicitly registered set that goes register requirement to point to that receiving element is received.
Below specify by an embodiment.
Embodiment six, S-CSCF remove register requirement decision logic embodiment to many registrations, referring to shown in Figure 10, comprise the following steps:
1, S-CSCF receives the register requirement of going of UE or user agent's initiation.
2, S-CSCF judge whether to exist with this request in IMPU, IMPI and the corresponding log-on message of heavy sign-on ID.
3, set up (log-on message) when step 2 Rule of judgment, then delete the log-on message of corresponding IMPU, IMPI and middle sign-on ID with identical IMPU/IMPI and heavy sign-on ID correspondence.
4, S-CSCF judges whether also to exist with going this register requirement and has identical IMPU/IMPI, but heavy sign-on ID all the other log-on messages inequality.
If 5 step 4 Rule of judgment are false (not had all the other log-on messages), then nullify the IMPU/IMPI of this log-on message correspondence, and the concentrated relevant IMPU of corresponding implicit registration; Flow process finishes if condition is false.
6, be false (log-on message that does not have identical IMPU/IMPI and heavy sign-on ID correspondence) when step 2 Rule of judgment, then carry out abnormality processing, process ends then.
In sum, the method of the sensing bind state of circuit domain of the embodiment of the invention, Apparatus and system, can make the attachment state of AS perception UE in the CS territory, thereby execution business that can be correct, and reach for some cross-domain business and can better carry out business control, improved user's business experience.
The many register methods and the device in the IMS territory of the embodiment of the invention when having realized that a certain input field under many registration scenarios initiates to go to register, avoid triggering the cancellation of corresponding implicitly registered set.Thereby can make S-CSCF correctly know the state of UE, thereby correct triggering to AS is professional, and then has improved user's business experience.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
