A local voice escape method, local gateway and system

Abstract

The embodiment of the invention discloses a local voice escape method, a local gateway and a system, which relate to the communication field and realize local voice escape without relying on the local gateway to configure the DNS proxy function or the user terminal to configure the server. The specific scheme is: detect the active state of the server recorded in the server monitoring list according to the preset detection period; the voice server in the Internet Protocol IP Multimedia Subsystem IMS network is pre-recorded in the server monitoring list; when the server is detected When all the servers in the monitoring list are in failure state, intercept the service data flow sent by the user terminal to the server; and provide corresponding service service response for the user terminal according to the content of the intercepted service data flow. The present invention is used in the process of voice escape.

Description

technical field [0001] The invention relates to the communication field, in particular to a local voice escape method, a local gateway and a system. Background technique [0002] The Internet protocol (Internet protocol, referred to as IP) multimedia subsystem (IP multimedia subsystem, referred to as IMS) is a network architecture to achieve network integration. With the development of communication technology, IMS can not only realize the original voice over Internet protocol , referred to as VOIP) service, can also more effectively manage network resources, user resources and application resources, so that users can use various terminals across various networks, so IMS is more and more widely used. [0003] In the establishment of an IMS network, it is generally based on public networks, and these networks generally cannot provide carrier-class reliability services, so network failures or equipment failures often occur, making IP phones unable to communicate with the centr...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the above-mentioned local voice escape, the inventor found that there are at least the following problems in the prior art: In the solution of prior art 1, to realize local escape, the local gateway must be configured with a DNS proxy so that the SIP service of the local gateway can be inserted into the According to the service priority returned by the DNS server, if the local gateway is not configured with a DNS proxy, local escape cannot be achieved

In the solution of the existing technology 2, the local gateways of different terminals are different, and need to be configured independently, which increases the deployment cost
