Call diversion system
First Claim
1. A method for forwarding incoming cellular communications to an aircraft, comprising:
- receiving a request to divert incoming calls for a cellular telephone number to a communication system on board an aircraft;
associating a divert on busy instruction with the cellular telephone number, the divert on busy instruction representing an instruction to forward an incoming call for the cellular telephone number to the communications system aboard the aircraft; and
considering a state of a cellular telephone associated with the cellular telephone number as busy, regardless of an actual state of the cellular telephone;
wherein, an incoming telephone call to the cellular telephone number is forwarded, consistent with said considering and in accordance with the divert on busy instruction, to the communications system on board the aircraft.

Abstract
An interface (52) is provided between a satellite telephone system (4) and a cellular telephone system (5) for allowing calls to a user'"'"'s cellular telephone to be diverted to a satellite telephone (25) when the user is unable to use his cellular telephone, for example when on board an aeroplane (2) fitted with a satellite telephone system (20). The user inserts a card (which may be the SIM of his mobile phone, or a card compatible with existing satellite telephone equipment) into a suitable reader in the satellite telephone (20), which causes the satellite ground station'"'"'s card verification system (42) to connect to a host cellular network (50). The host cellular network has an interface unit (52) which emulates the operation of a normal base station, so that the host cellular system (50) acts as if the mobile user'"'"'s terminal is roaming on the host network, but is currently “busy”. The interface (52) also resets the user'"'"'s existing call diversion instructions so that when the host cellular system (5) receives a busy tone frome the base station emulator (52), it routes calls to the directory number of the terminal (20).

10. A method for routing incoming cellular telephone traffic through a land-based host network to a cellular device user aboard an aircraft, the cellular device user having an associated cellular telephone number, comprising:
-
receiving, at the host network, a request to register the presence of the cellular device user aboard the aircraft; the host network advising the cellular device user'"'"'s home network that the cellular device user is within the operating jurisdiction of the host network; associating, at the host network, a primary divert on busy instruction with the cellular telephone number, the divert on busy instruction representing an instruction to divert an incoming call to a communication system on board the aircraft; and considering a current operational state associated with the cellular telephone number as busy, regardless of an actual operational state of the cellular device; wherein, upon receipt of an incoming call to the cellular telephone number, the host forwards an incoming call to the communication system on board the aircraft consistent with the primary divert on busy instruction. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of registering to divert a telephone call to a telecommunications device on-board a vehicle, the method comprising:
-
receiving first and second identification information, the first identification information being associated with a cellular device, the second identification information being associated with the telecommunications device; associating modified divert on busy instructions with the cellular device that identify the telecommunications device as a divert on busy instruction; and setting an indication of a status of the cellular device as busy regardless of an actual status of the cellular device. - View Dependent Claims (20, 21, 22, 23)

24. A method of registering to divert incoming cellular telephone calls to an on-board telecommunications device, the method comprising:
-
registering a cellular device as roaming on a host network regardless of the actual location of the cellular device relative to the host network; and updating, in response to said registering, a primary divert-on-busy instruction of the cellular device as an on-board telecommunication device. - View Dependent Claims (25, 26, 27, 28)

29. A method of receiving a telephonic call placed to a mobile station at a telecommunications device on-board a vehicle comprising:
-
receiving a call forwarded from a home network, the call being placed to the mobile station; returning a busy signal for the mobile station regardless of an actual state of the mobile station; accessing a divert-on-busy instruction for the mobile station; and forwarding the call to the vehicle consistent with said accessing; wherein the call terminates at the telecommunications device on-board the vehicle. - View Dependent Claims (30, 31, 32)
