METHOD FOR MANAGING OF SIGNALLING MESSAGE IN PATH-COUPLED SIGNALED PATHS TO MPLS-ENABLED CORE NETWORK

摘要

A method for processing a signaling message in an MPLS LSP based transmission network and a subscriber network supporting path-coupled signaling is provided to enhance scalability of a network by reducing a load which is added to the transmission network. A interaction supporting system is made up of a transmission network boundary router(120) and a resource management system(130). If a specified terminal(110) of a subscriber network transmits a path-coupled signaling message through a specified path(170), the transmission network boundary router connected to the subscriber network converts the message and transmits the converted message to the resource management system. The resource management system checks up the message to identify the subscriber network where a subscriber terminal(160) is located, a transmission network boundary router(140) connected with the subscriber network, and the resource management system(150). And the resource management system transmits the converted message to the identified resource management system so as to perform the path-coupled signaling on the path(190) between the boundary router and the terminal(160) of a called party.
