Problems solved by technology

[0005] In summary, during the entire registration and deregistration process, the calculation and transfer of the authentication vector takes a lot of time.
During the logout process, the authentication vector and other security context parameters need to be deleted, which not only increases the execution actions of the system, but also increases the time consumption of the entire logout process.
At the same time, if the authentication vector is not used up during the deregistration process, the calculation and generation of the authentication vector are not fully utilized in the whole process, which leads to complex functions of network elements and more message interactions in the registration process. The registration process takes a long time to process, the system load is heavy, and the service quality is poor

Abstract

The invention discloses a method and device for IP multimedia subsystem logout and login. The method and device is used for optimizing an IMS login process and reducing the times of message exchange so as to lower processing delay in the login process and improve service quality. The method for IMS logout comprises the steps that after a service call session control entity sends a confirmation message which is used for accepting a logout request sent by user equipment to an interrogating call session control entity, a security context timer corresponding to the user equipment is started; when the security context timer is in time-out, the service call session control entity deletes the security context of the user equipment.

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 server (Home Subscriber Server, HSS), and application server (Application Server, AS). Among them, among the multiple sub-processes included, the sub-process of Multimedia Authentication ...
