Abstract

A method of informing a network of a change of user equipment capability includes: stopping a registration timer on the user side set currently when the user equipment capability changes; sending a register request message carrying information of new user equipment capability to the network; analyzing, by the network, the register request message, and storing the information of new user equipment capability for reference by subsequent establishment of a session; stopping a current registration timer on the server side set for the user equipment; initiating a new registration timer on the server side for the user equipment; sending a response message carrying information of the new registration timer on the server side to the user equipment; resetting the registration timer on the user side based on information of the new registration timer on the server side in the response message. The capability change is informed to the network in time.

Claims

1. A method of informing a network of a change of user equipment capability, comprising:

stopping a registration timer on the user side set currently by a user equipment when the user equipment capability changes;

sending a register request message carrying information of new user equipment capability to the network;

analyzing, by the network, the register request message, and storing the information of new user equipment capability for reference by subsequent establishment of a session;

stopping a current registration timer on the server side set for the user equipment;

initiating a new registration timer on the server side for the user equipment;

sending a response message carrying information of the new registration timer on the server side to the user equipment;

resetting the registration timer on the user side based on information of the new registration timer on the server side in the response message.

2. The method of informing a network of a change of user equipment capability according to claim 1, wherein said response message is a 200 OK message.

3. The method of informing a network of a change of user equipment capability according to claim 1, wherein said information of the new user equipment capability is stored in network nodes responsible for processing a session.

4. The method of informing a network of a change of user equipment capability according to claim 1, wherein said information of the registration timer on the server side means a new time length set by the network for resetting the registration timer on the user side or the shortest and longest refresh time allowed by the network

5. The method of informing a network of user equipment capability according to claim 1, wherein if the register request message carries the information of user equipment capability and the current registration timer on the server side has not expired, the network determines that the register request message is one sent due to the user equipment capability change

6. The method of informing a network of change of user equipment capability according to claim 1, wherein said method is triggered automatically when the user equipment monitors a change of the user equipment capability or triggered manually.
