Abstract

A system and method of providing seamless interoperability for a mobile station roaming between cellular telecommunication systems (31) operating in multiple hyperbands such as the 1900-MHz PCS hyperband and the 800-MHz cellular telephone hyperband, utilizing United States cellular standards. An enhanced inter-exchange communications protocol based on IS-41 is utilized to communicate information required for seamless interoperability between mobile switching centers (MSCs) (MSC1 and MSC2). The enhanced inter-exchange communications protocol comprises a plurality of signaling messages (41 and 51) and a plurality of modified message parameters (42 and 52) within the signaling messages. The modified message parameters are modified to include information elements (43 and 53) required for seamless interoperability between the multi-hyperband capable exchanges and are added as optional (overriding) parameters to the signaling messages.
