Abstract: The invention relates to a method for controlling the operation of a short-range wireless terminal capable of operating in a first beacon-based network and in a second beacon-based network, and having an active state and a power save state in the first beacon-based network. For seamless operation in the two networks, the terminal moves to a power save state with respect to the first beacon-based network if operation in the second beacon-based network is required. However, the first beacon-based network is only informed that the terminal moves to a power save state and instead of powering down, the terminal becomes active in the second beacon-based network.

Abstract: The methods, apparatus, systems and computer program products provide for sensing a magnetic field, emitted by a short-range communication source, to activate short-range communication modules in a mobile terminal. In addition to sensing the magnetic field, the terminal may rely on other parameters, such as operational state of the terminal, contextual information and the like, to determine if the short-range communication module should be activated. As such, the invention reduces the overall power consumption of the terminal by limiting the active state of the short-range communication module. By conserving power the mobile terminal is capable of operating for longer periods of time without requiring charging or replacement of the power supply.

Abstract: The present invention provides an operational mode of communication which adjusts a transmitting power of a cellular system and a mobile terminal used inside a vehicle, such as an aircraft, so that the mobile terminals (102) inside the aircraft camp on the indoor cellular network (100) inside the aircraft and do not interfere with external cellular networks. This reduces possible electromagnetic interference with avionics inside the aircraft, because the transmitted power levels is limited. The frequency band used by the indoor cellular network can be determined by the service provider independent of frequency bands allocated by communication specifications and regulations. Conventional mobile terminals (102) and conventional base transceiver stations (104) applying the aircraft profile according to the invention can be used inside the aircraft while aboard to communicate with the conventional external cellular networks (150).
