A movable switching system provides cell, or small network of cells, which moves with the aircraft or other vehicle on which it is located, but whose operation appears to the user as an ordinary fixed base station of the "host " network to which it is connected. A cellular mobile switching centre (116), on board the aircraft, detects a call attempt or registration attempt from a mobile unit (110) and generates a temporary onboard identity for association with the mobile identity code. The cellular identity is passed to a network registration unit (145) to allow a location update to allow calls to the cellular telephone (110) to be routed to the mobile station (141). Consequently, any incoming calls intended for the mobile user will now be directed to the network (104), as the mobile user is currently registered there. |
