First Claim
1. A method for providing an operational mode of wireless communication between at least one mobile terminal and at least one first network device inside a vehicle, such as aircraft, the method comprising steps of:
- communicating from the mobile terminal information indicating an operational mode that the mobile terminal uses for a wireless connection between the mobile terminal and the first network device inside the aircraft, connecting the mobile terminal via the first network device inside the aircraft to wirelessly communicate with a second network device outside the aircraft, where the wireless connection between the first network device and the second network device uses an operational mode of communication capable of communicating with external wireless networks outside the aircraft, characterized by limiting a transmitting power value for a wireless connection between the mobile terminal and the first network device to a limit power value, selecting said limit power value on the basis of providing a determined quality of service of the connection and minimizing interference with external wireless networks, selecting at least one frequency value to establish a wireless connection between the mobile terminal and the first network device on the basis of minimizing the interference effect with external wireless networks, and configuring the operational mode of communication in the wireless connection inside the aircraft on the basis of said limit power value and said frequency value.

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).
