Cellular telecommunications network having seamless interoperability between exchanges while supporting operation in multiple frequency hyperbands |
摘要 |
A system and method of providing seamless interoperability for a mobile station roaming between cellular telecommunication systems 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). The enhanced inter-exchange communications protocol comprises a plurality of signaling messages and a plurality of modified message parameters within the signaling messages. The modified message parameters are modified to include information elements required for seamless interoperability between the multi-hyperband capable exchanges and are added as optional (overriding) parameters to the signaling messages. |
