Abstract

The embodiment of the invention provides an IMS network registration method and a related device, and relates to the field of communication. The terminal device establishes a bearer with the IMS network; receiving a response message returned by the IMS network based on the P-CSCF device discovery request sent by the terminal device, and when it is determined that the response message does not carry the address information of the P-CSCF device allocated by the IMS network, or the address information of the P-CSCF device carried in the response message is invalid, reading locally pre-configuredalternative address information, and initiating a registration request to the IMS network based on the alternative address information. Visibly, when the IMS network is abnormal and the address of theP-CSCF equipment cannot be returned; the terminal equipment is pre-configured with the alternative address information of the P-CSCF equipment, so that IMS registration can be performed by using thealternative address information, and the situation that the terminal equipment cannot be successfully registered to the IMS network due to the fact that the IMS network is abnormal is avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular to an IMS network registration method and a related device. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) network, the PS (Packet Switched, packet switching) call based on the IMS (Internet Protocol Multimedia Subsystem, IP Multimedia Subsystem) network is becoming more and more important, and some countries have begun to withdraw 2G, 3G Network, once the UE (User Equipment, user terminal) registers with the IMS network and there is a problem, it will cause the mobile phone to be unable to make calls. [0003] The CSCF (Call Session Control Function, call session control function) entity is a key component in the IMS network, and the P-CSCF (Proxy-CSCF, proxy call session control function) device is the first node for the UE to access the IMS network. Before the UE initiates a registration request to the IMS network, it needs to obtain the add...
