Abstract
Method and apparatus for messaging between disparate networks. A service control gateway (SCG) provides the capability to extend advanced intelligent network (AIN) services transparently between circuit switched and packet networks. In one embodiment, the invention works by translating signaling system 7 (SS7) transaction capabilities application part (TCAP) messages into session initiation protocol (SIP) INVITE messages. SIP messages, which may be responses to the translated messages referred to above, are translated back into TCAP messages. Data from messages is stored in an interaction database, a data structure maintained at the SCG. The SCG uses the interaction database to properly format translated messages for each network.
