Cellular telecommunications network having seamless interoperability between exchanges while providing voice, asynchronous data and facsimile services in multiple frequency hyperbands

A cellular telecommunications network providing seamless call delivery inter-change handoffs, inter-exchange cell reselections inter-hyperband handoffs, and inter-hyperband cell reselections for voice calls, asynchronous data calls, and facsimile calls for a mobile station roaming between multi-hyperband capable exchanges, said cellular telecommunications network comprising:

• a plurality of mobile switching centers (MSCs) having means for operating in a plurality of frequency hyperbands;
• a plurality of base stations connected to each of said plurality of MSCs, said base stations having transmission and reception equipment operating in the plurality of frequency hyperbands;
• an inter-exchange communications protocol for communicating information required for seamless interoperability between said plurality of MSCs and said plurality of frequency hyperbands, said inter-exchange communications protocol comprising:
• a plurality of signaling messages in an industry standard message format, and
• a plurality of modified message parameters within sad signaling messages, said modified message parameters including unmodified information elements, modified information elements, and new information elements which provide seamless call delivery, inter-exchange handoffs, inter-exchange cell reselections, inter-hyperband handoffs, and inter-hyperband cell reselections for voice calls, asynchronous data calls, and facsimile calls between said multi-hyperband capable exchanges and said plurality of frequency hyperbands.
