Abstract
A method for implementing a session border controller (SBC) pool and a SBC device are provided. In the present invention, an SBC pool is formed by at least two SBCs, the at least two SBCs are mutually backed up for disaster recovery and use a same Internet Protocol (IP) address for a terminal device, and whether the terminal device is registered in the SBC pool is determined; and if the terminal device has been registered in the SBC pool, a service message is forwarded to an SBC with which the terminal device is registered. In this way, it is avoided that SBC device disaster recovery places a special requirement for the terminal device, and the terminal device does not need to be configured with two IP addresses. Furthermore, all devices in the SBC pool can process the service message of the terminal device, thereby increasing a resource utilization rate.
