ABSTRACT:
A method and apparatus for providing wireless intelligent network services to mobile stations currently being served by a mobile switching center (S-MSC) that is not wireless intelligent network capable. The call is routed through a wireless intelligent network capable MSC (O-MSC). When the O-MSC receives the call, it requests instructions from a service control point (SCP) which provides a list of triggers for call states requiring further SCP instructions. Advantageously, this arrangement avoids the use of a double connection, using a loop-around trunk, in the O-MSC, as is required in the prior art.
