Node and onboard station for setting up at any time a call involving a passenger on a vehicle
First Claim
1. A system for enabling a call involving a passenger on a vehicle to be set up at any time, comprising:
- an onboard station for connecting voice terminals and data terminals to a satellite network disposed on said vehicle, and an intermediate network comprising at least one node connectable to said satellite network and to at least one terrestrial telecommunication network to associate a terrestrial telecommunication network directory number with a satellite network directory number for each passenger on said vehicle, said node comprising mobile terminal simulators that simulate the behavior of mobile terminals of the terrestrial telecommunication network, and for associating a terrestrial mobile telephone telecommunication network directory number with a satellite network directory number, said node comprises;
at least one base station simulator connected to said terrestrial mobile telephone network to simulate the behavior of a dummy base station of said terrestrial mobile telephone network, and n mobile terminal simulators connected to said base station simulator to simulate the behavior of n mobile terminals remaining at all times within the area of said base station and which correspond to n passengers in said vehicle, said n simulators being connected to said onboard station via said satellite network and being adapted to be called via said terrestrial mobile telephone network using said directory numbers of said n passengers, and retransmitting calls to n subscriber numbers of said satellite network respectively associated with said n directory numbers.

Abstract
Passengers on board a vehicle make and receive calls via a satellite network. That network sees each passenger involved in a call as a temporary dummy subscriber of the satellite network. Thus the satellite network is used to manage the roaming of passengers on aircraft. An intermediate network and the terrestrial mobile telephone network therefore do not need to manage the roaming of the aircraft. The terrestrial mobile telephone network sees each node of the intermediate network as a dummy base station and each passenger involved in a call as a dummy mobile subscriber of the terrestrial mobile telephone network, in the service area of one of the dummy base stations. The terrestrial fixed telephone network sees each passenger involved in a call as a subscriber of another fixed network managed by another operator. The intermediate network sees the satellite network as a standard terrestrial mobile telephone network, able to manage the roaming of its subscribers itself.

8. An onboard station for setting up a call involving a passenger on a vehicle at any time, said onboard station enabling voice terminals and data terminals in said vehicle to be connected to a satellite network which is in turn connected to a terrestrial mobile telephone network through an intermediate network, which onboard station comprises:
-
means for storing directory numbers of passengers in said vehicle who are subscribers to a terrestrial mobile telephone network and associating them with respective satellite network subscriber numbers, said means for storing includes a base station that sets-up a wireless transmission link with the passenger'"'"'s personal mobile terminal so as to receive the passenger'"'"'s directory number, and means for routing a call to a passenger on the basis of a satellite network subscriber number used to route said call, wherein said onboard station communicates with a management unit in the intermediate network to record call management data, and erases the stored directory numbers of passengers to allow the passenger'"'"'s personal mobile terminal to receive calls from the terrestrial mobile telephone network.

9. A system for enabling a call involving a passenger on a vehicle to be set up at any time, comprising:
-
an onboard station for connecting voice terminals and data terminals to a satellite network disposed on said vehicle, and an intermediate network comprising at least one node connectable to said satellite network and to at least one terrestrial telecommunication network to associate a terrestrial telecommunication network directory number with a satellite network directory number for each passenger on said vehicle, said node comprising mobile terminal simulators that simulate the behavior of mobile terminals of the terrestrial telecommunication network, wherein each mobile terminal simulator comprises means for recording in subscriber databases of said at least one terrestrial communication network, at an address corresponding to the directory number of the passenger, a presence of a dummy mobile terminal, in order to route calls addressed to the passenger to the mobile terminal simulator. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system for enabling a call involving a passenger on a vehicle to be set up at any time, comprising:
-
an onboard station for connecting voice terminals and data terminals to a satellite network disposed on said vehicle, and an intermediate network comprising at least one node connectable to said satellite network and to at least one terrestrial telecommunication network to associate a terrestrial telecommunication network directory number with a satellite network directory number for each passenger on said vehicle, said node comprising mobile terminal simulators that simulate the behavior of mobile terminals of the terrestrial telecommunication network, wherein each mobile terminal simulator comprises means for requesting the satellite network to set-up a call to the passenger, designated by the passenger'"'"'s subscriber number in the satellite network, if the mobile terminal simulator receives a call from the at least one terrestrial communication network containing the directory number of the passenger. - View Dependent Claims (16, 17, 18, 19, 20)
