Abstract: A cellular mobile telephone system usable on board a passenger transport vehicle includes a first transmitter-receiver station on board the vehicle and connected to an antenna external to the vehicle to establish an external radio link between the vehicle and a terrestrial mobile telephone network via a satellite. A base station system having at least one antenna inside the vehicle is connected to a base station controller. The base station system and the base station controller have functions analogous to those of a base station system in a standard mobile telephone network.

Abstract: A cellular mobile telephone system which can be used on board a vehicle enables conventional mobile telephones to be used on board an aircraft, for example. It includes a first transceiver on board the vehicle and connected to an antenna on the outside of the aircraft to set up an external radio link with a terrestrial mobile telephone network via a satellite. It further includes a second transceiver having an antenna inside the aircraft and connected to a base station controller. The second station and the base station controller have functions similar to those of a base station system in a conventional mobile telephone network, for example a GSM network. The base station controller is connected to the first transceiver. To prevent long signaling link set-up times, the base station controller includes software for setting up a signaling link between the aircraft and the terrestrial mobile telephone network in advance, as soon as at least one mobile telephone is switched on.

Abstract: A system enabling use of mobile telephone terminals to a first standard in a private telecommunication network to a second standard includes a GSM radio transceiver, a DECT radio transceiver and a converter for applying a GSM terminal declaration and location procedure. The system converts between the signaling protocol standardized by the GSM and a DECT/GAP signaling protocol accepted by the private automatic branch exchange. If necessary, it transcodes between the GSM speech code and a speech code accepted by the private automatic branch exchange.

Abstract: The server includes one pair of simulators for each pair of machines, a first machine and a second machine of any given pair being connected to respective ones of two simulators respectively simulating the behavior of the second machine and the behavior of the first machine. It further includes means for interconnecting all of the simulators, each simulator being capable of communicating with each of the other simulators. For a given pair of machines, the simulator of the second machine includes means for making the first machine believe that certain resources of a third machine are situated in the second machine of the pair in question. Application to providing new services, in particular for making it possible to use GSM terminals in a DECT private network.

Abstract: Apparatus for connecting telephone switch to fixed telephone network or PSTN via a radiotelephone network of GSM type or type derived therefrom. A fixed radiotelephone terminal (RT) has a processor that identifies calls containing an identity belonging to a predetermined set of international mobile subscriber identities (IMSIs), and calls containing an identity belonging to a predetermined set of temporary mobile subscriber identities (TMSIs), both of the sets corresponding to user terminals (UT1, . . . , UT10) which are connected to the switch. The radiotelephone network issues a distinct invoice for each user terminal (UT1, . . . , UT10) even though the same fixed radiotelephone terminal (RT) is used by a plurality of different users, and the radiotelephone network can perform direct inward dialing to each user terminal (UT1, . . . , UT10).
