Embodiment Construction

[0029] Embodiments of the present invention provide an IMS deregistration and registration method and device, which are used to optimize the IMS registration process and reduce the number of message interactions, thereby reducing the processing time delay of the registration process and improving service quality.

[0030] In the embodiment of the present invention, during the deregistration process, after the S-CSCF replies a 200 OK message to the UE, the third party deregistration process timer corresponding to the UE is started to control the initiation of the third party deregistration. If the UE initiates the registration process again before the third-party deregistration process timer expires, the S-CSCF compares the AS lists in the two consecutive registration processes (in the SAA of the SAR / SAA process, the HSS will carry the addresses of multiple ASs , form an AS list) to decide whether to initiate the third-party registration and third-party deregistration process. ...

Abstract

The invention discloses an IP multimedia subsystem (IMS) logoff and logon method and device so as to optimize an IMS logon process, reduce message exchange times, reduce processing time delay of the logon process and improve service quality. The IMS logoff method comprises the steps of after receiving Cx pull response messages sent by a home subscriber server (HSS), enabling a serving call session control function (S-CSCF) to send confirmation messages used for expressing acceptance of a logoff request of user equipment (UE) to an interrogating call session control function (I-CSCF) and start a third party logoff procedure timer of the UE; and when the third party logoff procedure timer of the UE is over time, enabling the S-CSCF to start the third party logoff process of the UE towards an application server (AS).

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an IP multimedia subsystem IMS deregistration and registration method and device. Background technique [0002] The IP Multimedia Subsystem (IMS) registration process occurs in various scenarios. The initial registration, deregistration, periodic registration refresh, registration and re-registration caused by changing the access point will all initiate the registration process. In the IMS registration process, user equipment (User Equipment, UE), proxy call session control entity (Proxy-CSCF, P-CSCF), query call session control entity (Interrogating-CSCF, I-CSCF), service call session Signaling interaction between the control entity (Serving-CSCF, S-CSCF), home subscription data service (Home Subscriber Server, HSS), and application server (Application Server, AS). Among the multiple sub-processes included, the Multimedia-Authentication-Request (MAR) and Multimed...
