Method for generating internetwork call routing automatically

Abstract

The invention discloses a method for generating internetwork call routing automatically, which is applied to a changeable topology distributed type IP (Internet Protocol) soft switching network. The method comprises the steps of: discovering and establishing adjacent relationships between switching nodes, interacting of interoffice call routing information based on the adjacent relationships, and automatically generating local call routing according to a configured routing strategy. The method when being applied to the switching environment of a bearer network with an IP layer between the switching nodes can generate call routing of each switching node in the distributed switching network automatically, rapidly and flexibly, finish updating of the call routing of all the switching nodes in the network automatically when the number routing change occurs due to the change of the switching topology, the Internet and the like, guarantee correct connection of the call, and can be applicable to special communication networks such as a mobile communication system for military use and an emergency communication system.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to a method for automatically generating an inter-network call route applied to a variable topology distributed IP softswitch network. Background technique [0002] When the communication network performs call service interworking between switching offices, a unified static data configuration of the entire network is required within the switching network. The call is routed through number routing analysis in each switching office that passes through, and then it is connected to the next switching office. To the switching node where the called party is located, the network service is connected to the Internet through the gateway switching node, thereby realizing the call connection process. This static call routing configuration implementation method can ensure that inter-network calls are accurately and accurately transmitted to the called party in accordance with the pre-set stra...

Problems solved by technology

[0003] In some dedicated communication networks, such as military mobile communication systems and emergency communication systems, in consideration of invulnerability and mobility, each switching node implements distributed switching, which can be used independently by a single node or in a network. In addition, switching nodes carry out mobile bearers, and when they are connected to other Internet systems, the network topology often changes during networking. Gateway switching nodes interconnected with other network systems also have network location variability. At this time, only static call routing configuration methods are used. , it is difficult to implement a unified configuration change of each node in the full switching network every time the call route changes, and it cannot adapt to the rapid change of the network topology
