Definitions
- the present invention relates to a telephone system for use in a vehicle, which is applicable to cellular telephone systems such as GSM or DCS cellular systems and U.S. standard systems.
- a telephone system for a vehicle comprising a vehicle transceiver, on board said vehicle, and connectable to a cellular telephone network for bi-directional communication therewith, a server terminal, on board said vehicle, connected to said transceiver and having an identification address, a plurality of user terminals, distributed on board the vehicle, each capable of accepting an identity of a user of the cellular telephone system and each connected to said server terminal whereby a plurality of users may communicate simultaneously with said network via the server terminal, and a location data base for identifying users of the cellular telephone system when their identifies are accepted by respective user terminals and for associating those users with said identification address to permit communication to be established between those users and the cellular telephone system via the server terminal.
- the telephone system further comprises a plurality of interface systems each for providing a communication path between said transceiver and a switching network within a respective region, the switching network being connected to said telephone network and connectable to at least one of said interface systems when the vehicle is located in the region corresponding to that interface system thereby providing a communication path between said transceiver and said telephone network, and control apparatus operable to select which one of said interface systems should provide the communication path to the transceiver when the vehicle is located in the regions corresponding to a plurality of interface systems.
- the location data base is connected to said telephone network and is accessible to enable said network to locate each of said accepted users and thereby enable bi-directional communication between said telephone network and each of said identified users.
- control apparatus is further operable to control simultaneously the handover of said established communication when the vehicle moves from a first one of said regions to a second one of said regions.
- a method of operating a telephone system within a vehicle to enable a plurality of users to simultaneously communicate with a ground based cellular telephone system comprises establishing a fixed connection through a plurality of user terminals distributed on board the vehicle to a server terminal having an identification address, establishing a connection between said server terminal and an onboard transceiver, identifying users of the cellular telephone system when their identities are accepted by respective user terminals, and associating identified users with said identification address to permit simultaneous communication to be established between those users and the cellular telephone system via the server terminal.
- the vehicle may suitably be an aircraft, train or boat.
- Figure 1 is a schematic view of a telephone communication system.
- Figure 2 is a schematic view of the vehicle telephone systems.
- Figure 3 schematically shows the aircraft in transit.
- the telephone system of this example enables subscribers to a cellular mobile telephone system to use telephones within an aircraft without causing interference with the aircraft equipment.
- the system is particularly applicable to subscribers to a known GSM/DCS network in which the user has a SIM card which the user may locate in a receptor in a phone to use the services available to him.
- the system may however be used with any mobile telephone system.
- a plurality of users within an aircraft 10 are able to transmit or receive telephone messages through a transceiver located within the aircraft 10 which communicates via a satellite 12 to a ground earth station 14 using standard E1-link (CEPT E1) links 11 and 13.
- IP internet protocol
- MSC Mobile switching centre
- PSTN public service telephone network
- the IP system 16 is integrated into the conventional cellular network topology as one part of the network structure. It is one alternative medium to link the mobile traffic from one location to another. At GES the Gl signal is converted into IP traffic.
- Figure 2 illustrates the aircraft telephone system 20 in more detail.
- the transmission and receipt of telephone message to and from the aircraft 10 are handled by a transceiver which in the example is an aeronautical earth station (AES).
- AES aeronautical earth station
- the aeronautical earth station communicates with a satellite 12 via E1 link 11 in a conventional way.
- the aeronautical earth station is connected to a server terminal 23 such as a PC server terminal via a fixed connection 22 which may be a CEPT-E1 2 Mbit fixed connection.
- the PC has software which controls the mobile telephones 25 which are distributed throughout the aircraft 10.
- Each mobile telephone (or user terminal) is connected via a fixed connection 26 such as an RS-232 serial bus or universal serial bus (USB).
- RS-232 serial bus or universal serial bus (USB).
- USB universal serial bus
- the actual RS-232/USB network can be built by using twisted pair, fibre links or tiered star connections.
- the user By inserting the SIM card into the aircraft mobile or by connecting the user's own mobile the user indicates when he wishes to use the telephone system so that he is identified by his own telephone number. This enables the user to be contacted in the aircraft and to utilise the services which are normally available and also allows the user to be identified for billing.
- the mobile telephones 25 are connected into an Intranet cluster in the aircraft mobile network.
- a user places his SIM card into the aircraft mobile telephone 25, or the telephone is connected to the transceiver via the PC server terminal and can thereby communicate with the ground based telephone network via satellite link.
- the mobile switching centre which is part of the telephone network is updated with the SIM identity.
- the cellular network thereafter identifies that that the user is in the aircraft.
- the server PC 23 has its own identification address which is equivalent to the address stored in the visitor location register (VLR) database in a conventional mobile switching centre (MSC).
- the database could be in any suitable form and stored at any suitable unit; in this example it is stored in an Intranet location register (ILR) database.
- the Intranet location register database is updated when the SIM card is replaced by a user in the aircraft so that the mobile has a new location area code (LAC).
- LAC new location area code
- Each aircraft mobile network (AMNW) forms one location area and users in the aircraft are always associated with that area code when connected in the aircraft.
- an Intranet mobile cluster whereby a plurality of users are associated with a single IP address allows the handover of calls to be carried out more conveniently.
- the Inmarsat satellite system has at least three satellites 30 in orbit each of which covers a certain region or area over the globe 32.
- One handover area is above the Norwegian sea.
- the new routing ground earth station therefore has to be selected in accordance with the position of the aircraft.
- the telephone system therefore selects which one of the satellites and ground earth stations should provide the communication path to the transceiver when the aircraft is located in regions corresponding to more than one satellite to provide the strongest signal. As the aircraft moves from one region to another the IP address of the aeronautical mobile network remains the same. This minimises the chance that the short satellite link timeout, which affects calls to and from the aircraft, results in calls being dropped.
