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.
