Abstract
An emulator functionality is provided at both ends of a satellite communication link that is used between wireless network cells inside a vehicle, such as an aircraft, and a terrestrial communication system. The emulator is capable of providing required state signalling without a connection between a base station of the wireless network inside the vehicle and a base station controller of the terrestrial communication system. In accordance with an exemplary embodiment of the invention the satellite communication link can be switched to an off-state when it is not needed for transferring calls or other information. A further non-limiting exemplary embodiment of the invention provides for a use of alternative satellite connections depending on the location of the vehicle is provided.
