Method and apparatus for a signalling message transport mechanism
First Claim
1. A method of transmitting signalling information in a telecommunications network between peer user/application parts, the method comprising:
- transferring signalling information 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 a peer user/application part is located;
determining at the MTP level 3, from said destination signalling point identifier, a destination address suitable for conveying the signalling information to the destination signalling point or to an intermediate signalling point en route to the destination signalling point;
providing an adaptation layer between the MTP level 3 and the IP part at the originating signalling point, as well as at intermediate and destination signalling points, the adaptation layer providing an interface between the MTP level 3 and TCP/UDP levels and listening to a predetermined port number to receive and process incoming TCP connections or UDP packets; and
in the event that said destination address is an Internet Protocol (IP) address and port numbertransferring, via the adaptation layer, the signalling information and the determined IP address and port number to an IP part for transmission over an IP network to the destination or intermediate signalling point.

Abstract
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/application part is located. The MTP level 3 determines from the destination signalling point identifier, a destination address suitable for conveying the signalling information to the destination signalling point. In the event that the destination address is an Internet Protocol (IP) address and Port number, the 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.

10. Apparatus for transmitting signalling information in a telecommunications network between peer user/application parts, the apparatus comprising:
-
first processing means implementing a Message Transfer Part (MTP) level 3 for receiving signalling information from a first user/application part, the information including a destination signalling point identifier identifying the signalling point at which a peer user/application part is located, the MTP level 3 determining from said destination signalling point identifier, a destination address suitable for conveying the signalling information to the destination signalling point or to an intermediate signalling point en route to the destination signalling point; second processing means implementing an IP part for transmitting the signalling information and the determined IP address and port number over an IP network to the destination or intermediate signalling point, in the event that said destination address is an IP address and port number; and an adaptation layer between the MTP level 3 and the IP part at the originating, intermediate and destination signaling points, the adaptation layer providing an interface between the MTP level 3 and Transmission Control Protocol/User Datagram Protocol (TCP/UDP) levels and listening to a predetermined port number to receive and process incoming TCP connections or UDP packets.
