Abstract
Embodiments of the present invention relate to the communications field and disclose a method, a local gateway, and a system for local voice survivability, to implement local voice survivability without configuring a DNS proxy function on a local gateway or configuring a server on a user terminal. A specific solution is: detecting, according to a preset detection period, an activity state of a server recorded in a server monitoring list, where the server monitoring list records a voice server on an Internet protocol IP multimedia subsystem IMS network in advance; intercepting, when it is detected that all servers in the server monitoring list are in an unavailable state, a service data stream sent by a user terminal to the server; and providing a corresponding service response for the user terminal according to content of the intercepted service data stream. The present invention applies to a process of voice survivability.
