First Claim
1. A method of converting data messages originally formatted for transmission over a first telecommunications network for generation of a display on a display unit of a first type, the conversion being such that messages can be transmitted over another telecommunications network for display by a selected display by a selected display unit of a second type forming part of a server-based information display system, wherein the address information in the original data message is replaced by address information appropriate to the selected display unit to generate an amended data message, and a new data message is created, addressed to the server of the information display system and having the amended data message as payload, and wherein the server converts the amended data message into control instructions suitable to display the information content of the data message on the information display unit identified in the amended data message.

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 handset (25) when the user is unable to use his cellular telephone, for example when on board an aircraft (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 from the base station emulator (52), it routes calls to the directory number of the terminal (20). Data messages originally formatted for transmission over the cellular telecommunications network for generation of a display on a display unit of a cellular telephone, can instead be transmitted over the satellite network for display on the information and entertainment system of the aircraft by replacing the address information in the original data message by address information appropriate to the selected display unit to generate an amended data message. A new data message is created, addressed to the server of the information display system and having the amended data message as payload. The onboard server has means for converting the amended data message into control instructions suitable to display the information content of the data message on the information display unit identified in the amended data message.

12. A method of forwarding a data message to a vehicle, comprising:
-
registering a user'"'"'s cellular identity as present aboard a vehicle; receiving a data message, configured for transmission through a first type of transmission system and intended for the cellular telephone associated with the user'"'"'s cellular identity, the data message including at including at least a first address and a data packet, the first address being associated with the user'"'"'s cellular identity; associating the data packet with a destination address, the destination address representing a node aboard the vehicle, said associating including reconfiguring the data message for transmission over a second type of transmission system; and forwarding the data packet to the vehicle consistent with the destination address through the second type of transmission system different from the first type. - View Dependent Claims (13, 14, 15, 16, 17)

20. A method of forwarding a data message, the method comprising:
-
registering the user'"'"'s cellular identity as present aboard a vehicle; linking the user'"'"'s cellular identity with the destination address; receiving an original data message intended for a user'"'"'s cellular telephone and configured for transmission over the public switched telephone network, the data message including at including at least a first address and a data packet, the first address being associated with the user'"'"'s cellular identity; determining the user'"'"'s cellular identity from the original data message, and locating the destination address from the link between the user'"'"'s cellular identity and the destination address, the destination address representing a display aboard the vehicle associated with the user'"'"'s cellular identity; forming a new data message including at least the destination address and data packet, the new data message being configured for transmission over a computer network; forwarding the new data message to the vehicle consistent with the destination address. - View Dependent Claims (21, 22, 23, 24, 25)

26. An apparatus for a data message to a vehicle, comprising:
-
an interface including at least a register, a processor, and a transmitter and being configured to; receive an original data message intended for a user'"'"'s cellular telephone and configured for transmission over the public switched telephone network, the data message including at including at least a first address and a data packet, the first address being associated with the user'"'"'s cellular identity; identify a destination address, the destination address representing a display aboard the vehicle associated with the user'"'"'s cellular identity; form a new data message including at least the destination address and data packet, the new data message being configured for transmission over a computer network; and forward the new data message to the vehicle consistent with the destination address; said interface being configured to send an advisory message to said destination address the advisory message indicating that a message is available for forwarding and requesting authorization to forward the message. - View Dependent Claims (27)
