Abstract:
An interface between an SS7 gateway and an IP network allows application layer data, such as MAP and TCAP messages, to be transported unchanged through the interface. The invention also provides a protocol for transporting MAP and TCAP messages that eliminates the need for SS7 protocols, and in particular, eliminates the need to implement the Signaling Connection Control Part (SCCP). The interface is particularly useful for connecting a private wireless office system to an SS7 network to allow roaming between the private wireless office telephone system and the PLMN.
