ABSTRACT:
A method of transmitting signalling information in a Public Land Mobile Network (PLMN) between a pair of peer application part. An adaptation layer is interposed between the SCCP of an SS7 network and a TCP/IP part to allow signalling data to be transmitted to and from the SCCP via an IP based network. The adaptation layer provides for translation between Destination Point Codes (DPCs) and or global titles, used as addresses in the SS7 network, and IP addresses/port numbers for use in the IP network. The adaptation layer also provides for formatting of SCCP messages suitable for processing by the TCP/IP layers, and also for formatting signalling information flowing in the reverse direction.
