Abstract

The invention provides an IMS registration method, an S-CSCF and a terminal. The IMS registration method comprises steps that the present registration expriation date of a terminal registration IMS is acquired; whether time difference of the present time and the cut-off time of the present registration expriation date is smaller than a pre-determined threshold; if the time difference is smaller than the pre-determined threshold, the registration expriation date is prolonged according to preset rules. The method is advantaged in that stable transition of the IMS registration expriation date can be realized in a terminal conversation process, user experience is improved, and increase of a signaling load during IPSec re-negotiation in a conversation process can be avoided.

Description

technical field [0001] The invention relates to the technical field of communication, and in particular to an IMS registration method, an S-CSCF and a terminal. Background technique [0002] Generally, if a user wants to enjoy the rich services provided by the Internet Protocol Multimedia Subsystem (IMS for short), he must first register with the IMS network. After the registration is successful, the UE will receive a timeout value (Expires). The value indicates the valid period for UE to register with the IMS network. When the valid period expires, the UE must re-initiate the registration process to maintain the validity of its public user identity, otherwise the serving call session control function server (Serving-CSCF, referred to as S-CSCF) will delete The UE cannot enjoy various services provided by the IMS network naturally. [0003] However, in the live network, it often occurs that the validity period of the IMS registration expires during the user's call, which br...
