Telecommunications signalling using the internet protocol
View Patent ↗When a telecommunications network involves use of the Internet Protocol, signalling information is passed by providing between a user and the Internet Protocol an interface protocol ( 56 ) which interfaces with one or both of the Transport Control Protocol and the User Datagram Protocol. The interface protocol layer provides selected parts of SS7 facilities.
1. A method of providing a user of a telecommunications network with Signalling System Number 7 functionality, the network operating Internet Protocol and at least one of Transport Control Protocol and User Datagram Protocol and having between the user and the Core Network of the telecommunications network at least one interface, characterised by providing between the user, and the Internet Protocol an interface protocol layer, said interface protocol layer interfacing with at least one of Transport Control Protocol and User Datagram Protocol whereby Signalling System Number 7 information is transmitted across said at least one interface,
wherein the interface protocol layer is provided between the user and a signalling application adopting Signalling Connection Control Protocol Service Access Points (SCCP SAPs) to access the signalling transport service and the Internet Protocol,
and wherein, the interface protocol layer providing both connectionless and connection-oriented functions of SCCP SAPs.
