Method for extending IP signaling system M3UA route supervising function

Abstract

The invention discloses an expanding method of the M3UA routing management function in an IP signaling system. The method includes the following steps: an M3UA protocol is used for communication between a signaling point and a signaling transfer point within an IP signaling network, or for communication among signaling transfer points. The routing keyword AS is arranged on a signaling point or a signaling transfer point. ASP or SGP and IP service processes and the priority of a routing are set up. A routing is used to manage message and exchange routing information among signaling points or among signaling transfer points. The signaling points or the signaling transfer points maintain the own routing lists according to the routing management information received together with the routing status of adjacent signaling points. The invention expands the present normal routing management function of an M3UA, thereby guaranteeing the reliability of the running of an IP network.

Description

technical field [0001] The invention relates to an extension technology of M3UA of an IP signaling system, in particular to an extension method of an M3UA routing management function of an IP signaling system. Background technique [0002] In traditional circuit-switching-based telecommunication networks, Signaling System No. 7 (SSNo.7, Signaling System No.7) is widely used to complete the exchange of control information. With the wide application of IP networks and the integration of multiple networks The goal is the integration of circuit switching networks and IP packet switching networks and the need to transmit traditional signaling in IP packet networks. For this reason, the Internet Engineering Task Force (ETF, The Internet Engineering Task Force) has formulated Sigtran (IP SignalingTransfer, IP Signaling transmission) series specifications, including a variety of adaptation protocols M3UA. [0003] In the traditional No.7 signaling system, the ITU (International Tel...

Problems solved by technology

[0004] The newly proposed Sigtran system pays more attention to the end-to-end adaptation transmission of signaling messages. Currently, the most commonly used L3 adaptation protocol M3UA only describes the signaling gateway (SG, Signal Gateway) and IP signaling point (IPSP, Routing management between Signaling Points, but lacks the functions of signaling routing management between signaling points (SPs) and signaling transfer points (STPs) in IP signaling networks, as well as between STPs and STPs
