ABSTRACT:
A system and method for providing two-way in-flight radio telecommunications on board an aircraft is disclosed. The radio telecommunication system includes a Gateway Mobile Switching Center (G-MSC), an Aircraft In-flight System Controller (AISC) located on board a subscriber's aircraft, a Ground In-flight System Controller (GISC), a satellite to relay messages and calls from the GISC and AISC, and a Home Location Register (HLR) which provides routing and location information for use by the GISC and the G-MSC. In an alternate embodiment of the invention, a system and method for using a mobile phone on an aircraft is disclosed. A mobile phone is connected to a seat terminal located on an aircraft by a co-ax cable. The radio frequency (RF) signals produced by a mobile phone pass through a coax cable to an Airborne Radio Base Station (A-RBS). The A-RBS converts the RF signals into signals which do not interfere with the aircraft's navigational and communication equipment and are compatible with the GISC and multiple cellular networks. These converted signals are then transmitted via satellite to a cellular network.
