Embodiment Construction

[0022] Service interruption among the present invention refers to that in the network that signaling end point, signaling gateway and media gateway controller form, the application server process (ASP) on the media gateway controller cannot transmit the second layer user adaptation of signaling transmission protocol layer user messages that cause service interruption of its users.

[0023] In order to avoid the loss of signaling messages caused by application server (AS) service interruption, when the application server service interruption occurs, the user adaptation layer of the signaling transmission protocol layer 2 reports the corresponding type of information to the layer 2 protocol it serves on the signaling gateway side. The service interruption primitive; on the application server process side on the media gateway controller, the user adaptation layer of the second layer of the signaling transport protocol reports the service interruption primitive of the corresponding...

Abstract

The invention discloses a service interruption processing method, as the service interruption of an application server happens, on the side of signalling gateway and on the course side of the application server, according to the protocol type, using MTP level-2 user adaptation layer (M2UA) to report corresponding original language of service interruption to its user; using the user to disconnect all the links processed by the application server; and as the service is recovered, notifying the user.

Description

technical field [0001] The invention relates to communication network technology, in particular to a processing method for service interruption in a signaling system. Background technique [0002] Signaling system is the key technology of modern communication network, and the reliable transmission of signaling messages by telecommunication equipment is the key to ensure high availability of telecommunication network. In the traditional telecommunication network, there are already a series of norms and technologies to ensure the reliability of the signaling system, such as the currently mature narrowband No.7 signaling system. With the gradual maturity of IP packet network technology, IP packet network can be used to carry voice, data, multimedia and other services. The traditional circuit-switched network and packet network are in the stage of integration. In order to realize the intercommunication between traditional circuit-switched network and IP packet network, There is...
