The information including the IP address of the IMS terminal may also be carried in the second authentication request message in this step.

Step 304: The configuration server completes the authentication according to the recalculated authentication information, determines an address list corresponding to the IP address, and carries the address list in a reset message and sends the message to the IMS terminal.

For the implementation of determining the address list corresponding to the IP address by the configuration server, refer to step 102. The description in the description is not repeated here.

The reset message can be implemented by a message package message.

Step 305: The IMS terminal sends a replace response message to the configuration server. The reset response message may be implemented by a message package message.

Step 306: The configuration server sends a finish session message to the IMS terminal. Then, the IMS terminal can select an address in the address list, and access the SBC corresponding to the address according to the address; wherein, by way of example and not limitation, in an implementation manner of the embodiment of the present invention, the IMS The terminal may randomly select an address in the address list, and access the corresponding SBC according to the randomly selected address. In another implementation manner of the embodiment of the present invention, the IMS terminal may select the distance from the IMS in the address list.
