AI Technical Summary

Technical Problem

In the IMS network, when third-party registration fails, the user equipment and the agent call session control function entity cannot learn of the registration failure in time, resulting in data inconsistency and affecting the normality of the user's use of the IMS communication network.

Method used

Introduce a waiting timer mechanism. After the user equipment completes registration, the S-CSCF entity starts the timer and performs third-party registration when the timer arrives to ensure that the user equipment and agent call session control function entity can learn the registration status in time and avoid data Inconsistent.

Benefits of technology

Through the waiting timer mechanism, it is ensured that user equipment and agent call session control functional entities can handle exceptions of third-party registration failures in a timely manner, avoiding data inconsistencies and improving user registration success rate and network stability.

Abstract

The present invention discloses a third party registration processing method based on the IMS network, which comprises that a UE completes the registration on a S-CSCF entity; the S-CSCF entity starts a waiting timer; the UE and a P-CSCF entity initiate and complete a registration status subscribing respectively to the S-CSCF entity; the S-CSCF entity initiate a third party registration to an AS when the waiting time of the waiting timer is enough. Through the present invention, the S-CSCF entity performs a waiting after the UE is successfully registered, to make the subscribing success of the registration status of the P-CSCF and the UE take precedence over the third party registration and avoid the situation of conflicting data of the UE, the P-CSCF, the S-CSCF and an HSS, to make the UE, the P-CSCF and the S-CSCF effectively process the abnormal circumstance occurred when the third party registration fails.
