SIGNALLING MESSAGE TRANSPORT MECHANISM

摘要

A method of transmitting signalling information in a telecommunications network between peer user/application parts. Signalling information is transferred from a first user/application part to a Message Transfer Part (MTP) level 3, the information including a destination signalling point identifier identifying the signalling point at which the peer user/applicati on part is located. The MTP level 3 determines from the destination signalling point identifier, a destination address suitable for conveying the signallin g information to the destination signalling point. In the event that the destination address is an Internet Protocol (IP) address and port number, th e signalling information and the determined IP address and port number are transferred to an IP part for transmission over an IP network to the destination signalling point.
