Description / Abstract: The scope of this standard are the services, information flows and message mappings which require interworking and interoperability functional specifications to support roaming between ANSI-41 MAP and GSM MAP networks. The scope of this volume is to provide a description of interstandard roaming along with an overview and network reference model for the Interworking and Interoperability Function (IIF).
Purpose
The purpose for this standard is to define and describe the functions necessary for roaming between ANSI-41 MAP and GSM MAP based networks in the support of roaming subscribers. This includes a capability to allow a subscriber to an ANSI-41 based network (e.g., a TDMA or CDMA native subscriber) with a mobile terminal supporting GPRS service to roam to a GPRS network in GSM Foreign Mode.
