The Telecommunications Industry Association has published a new joint standard, GSM MAP and TIA-41 MAP -- Revision B -- cdma2000 Support, J-STD-038-B.
The document is a revision of J-STD-038-A.
The scope of this standard is the services, information flows and message mappings that require interworking and interoperability functional specifications to support roaming between ANSI-41 MAP and GSM MAP networks.
The purpose of 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.
This standard describes an interworking and interoperability function to support this cross-technology roaming between ANSI-41 and GSM networks. It also defines the required network message mappings between ANSI-41 MAP and GSM MAP to support the mobile terminal and associated services. This standard includes the support of cross-technology roaming from an ANSI-41-based network to a GPRS network.
J-STD-038-B was created by TIA TR-45.2 Subcommittee on Wireless Intersystem Technology and ATIS Wireless Technologies and Systems Committee (formerly Committee T1's Technical Subcommittee T1P1) and released in August.
The TIA is based in Arlington, VA. For more information visit www.tiaonline.org.
