Method, system and network for establishing a telephonic connection towards persons in closed places, like transportation systems

The invention relates to a method of constructing a Telecommunications connection to a person who is in a stationary or mobile, spatially largely completed Device, in particular in a building or in a Passenger transportation means (airplane) is, within which several, operated by a private branch exchange of the device (internal) Communications terminals are, one (private) Telecommunications terminal of the person in a particular public telecommunications network a (personal) number is assigned. The invention also relates to a corresponding A telecommunications system for stationary or mobile, are each a forming spatially largely self-contained unit facilities, particularly for buildings or means of passenger transport (plane) with a provided within the device, and from outside the Means callable PBX and with several within the means provided, operated by the PBX (Internal) communication terminals, and a corresponding Telecommunications network.

Are generally known methods and telecommunications systems, as in the field of office communication, in which calls from a central PBX (exchange) to corresponding Extension terminals, in particular to phones relayed.

In addition, telecommunication systems with mobile Telecommunications terminal equipment, so-called mobile radio systems known that offer a high degree of mobility. Each participants is a assigned personal number under which he is always achievable, provided he is in the approximate range of Verso mobile radio system.

From DE 196 18 531 C1 is known, a call from a Telecommunications network, namely the GSM mobile network (GSM: Global System for Mobile Communications) to a PBX of a private network, namely to a DECT system (DECT: Digital Enhanced Cordless Telephone) forward, if the participants in a spatially sealed device is, as in his company where PBX is installed. The described therein PBX is connected via lines to the mobile switching center connected. The call is from there, along with a phone number, the so-called "branch routing number" to the PBX diverted. This number is instead of Location information, the so-called "location area identity") in the registered subscriber file of the mobile radio system. Based on these Number can be seen how the participants about the PBX is reachable in the private network. However, in DE 196 18 531 does not describes how the call from the PBX to that Communication terminal (DECT handset) is passed, the of Participants may use. Diversion described is not possible, if the subscriber the service area of ​​the mobile radio system left and one in a mobile device, such as in Aircraft is. Especially for business customers, for trips in Aircraft on the agenda, the availability would be in desirable to utilize aircraft time on the plane to productive can.

Currently only calls can from the plane to a Participants at the bottom by means of a credit card or a telephone credit card (Telephone calling card) are deducted, including in Aircraft increasingly phones are at almost every seat.

Thus, for example from US-A-5,592,539 is a telecommunications system , in which a passenger of a flight of an aircraft receive remote call from a ground station and a special Destination of a ground-based telecommunications network is forwarded. Given on the plane is a telephone station with Credit card reader, via which the telecommunications with the Radio ground station takes place.

In other spatially largely completed facilities such as eg in ships or trains, as well as such organizations as eg underground mines, where a telecommunications via the public telecommunications network can not take place or where an electromagnetic radio link due to interference or other reasons, for safety reasons, must not take place would, the accessibility of a person within these devices extremely desirable.

The present invention is therefore the object of a A method and a telecommunication system of each initially educate mentioned type such that one on one Telecommunications network person participating in stationary or mobile, spatially largely completed facilities continue their existing number will remain accessible, as well as a to provide appropriate telecommunications network.

This object is in the process mentioned inventively achieved in that at least during the stay of the person in the device assignment of their personal Phone number to that internal communication terminal that the Person is assigned during their stay at the facility, Saving that a private in the telecommunications terminal the person directed call together with the personal number is redirected to the PBX and that on the basis of stored assignment to the personal number assigned determined internal communication terminal and the call to this internal communication terminal is forwarded.

So at least during the stay of the person at the facility, the Mapping their existing number to that of internal Communication terminal that the person during their stay is assigned to the device, it is stored that one of the personal phone number of person-related call, together with the personal phone number or a corresponding identifier to the PBX is diverted and stored on the basis of that Mapping the assigned personal identification number or determined internal communication terminal and the call to this internal communication terminal is forwarded.

This allows, for example, in an airplane for outgoing calls already provided for internal communication terminals (Onboard phones) according to the invention now used for incoming calls will. These directed the relevant airline for each aircraft each have a special phone number, as airline passengers Call forward for looking at their personal number calls is used. Under this special phone number is the PBX in Aircraft reached. As well as the personal telephone number of the Participant (flight passenger), or a corresponding unique identifier (Seat number) is also transmitted, the call to the subscriber can are forwarded after its associated internal board telephone has been established on the basis of personal number or identifier.

The identifier may, for example as so-called Calling Party Address (CgPA) to To be available. Diversion can still by a time dependence be supplemented to start after a certain time, all calls for the redirect participants to this special number.

In an advantageous embodiment of the invention, the Communication link between the PBX and its internal communications terminals wirelessly, in particular by means Infrared signals via the infrared telephones, which are used as handsets. If electromagnetic interference within the device no Problem is, the internal communication terminal equipment can also his radio telephone, in particular the personal mobile phones Participants (passengers).

The assignment of the personal telephone number of the private Telecommunications terminal equipment to the respective internal Communication terminal and the diversion can in Means about there assigned internal Communication terminal, ie the plane at about the respective Seating provided internal board telephone, done. Each flight passenger can to decentralized means of his mobile Telecommunications terminal equipment located disk, in particular by means of its SIM (Subscriber Identification Module) card, register via the internal on-board telephone to the PBX. there is between his personal phone number and the internal board Telephone by which internal numbers or using the seat number one prepared map that on the PBX or in a located soil database is stored. The assignment can also take place centrally in a simple manner, the moment you enter by Means the personal numbers of the persons to whom the assigned means an internal communication terminal is to be taken and in conjunction with the in each case with the identifier the assigned internal communication terminal, ie, with their internal numbers or with the seat number, stored. Accordingly, the device can also already centrally upon entering the Redirecting addressed to personal phones calls to the PBX are triggered.

Especially when a telecommunication connection with an airplane or with a ship, it is advantageous when the telecommunications connection between the private telecommunications terminal equipment and the PBX centrally via a radio base station on the ground. This radio base station is for example a satellite radio station, in addition to usual operating radio transmitting telecommunications link manufactures by plane or its PBX. Already in the Radio base station, the assignment of the personal telephone number of a Flight passenger to his assigned aircraft in internal telephone done and a diverted call, together with a personal Number corresponding identifier, for example with the seat number or with the internal number of this seat assigned internal Phone will be forwarded to the PBX of the aircraft.

In a hospital, including in particular in buildings or even in Underground mines, communication, with the PBX wires via a corresponding base station and via connecting lines. For mobile devices, particularly in aircraft and ships, carried the Telecommunications link between the PBX wirelessly entsperechende a radio base station.

The above object is in a telecommunications system type stated by assigning means, in the at least during the stay of the person at the facility an assignment of their personal phone number to that of internal Communication terminal that the person during their stay is assigned to the device is saved to a private to Telecommunications terminal of the person up call together with the personal call number to the PBX redirect, wherein the allocation means stored on the basis of Mapping the personal number assigned internal determined communication terminal and forwarding calls to these internal communication terminal controls.

Thus, there is an assignment device in which the assignment of the (Personal) number of the person assigned (private) Telecommunications terminal equipment of a particular public Telecommunications network to that of internal Communication terminal that the person, at least during their is assigned the stay at the facility is stored, one of the personal number and directed together with this personal phone number or a corresponding identifier Diverted Call to exchange information with the allocator to the appropriate internal communication terminal of PBX is forwarded. With this The telecommunications system may be those already mentioned with regard to the achieve process described advantages.

In a preferred embodiment of the invention Telecommunication system, the PBX is a so-called PBX (Private Branch eXchange) or a PABX (Private Automatic Branch eXchange).

In facilities where electromagnetic interference no problem represent, the communication link between the PBX and its internal communications terminals done with electromagnetic radio signals wirelessly. For a interference-free wireless communication can also infrared phones internal communications terminals are used.

The mapping device is preferably a computer-controlled Database that, for example, within the device, eg on board of the aircraft, may be located. With the co-assigned personal Number is then only on board the aircraft with the help of Database assigning the personal telephone number of every internal telephone.

In a preferred embodiment, a radio base station provided by means of the telecommunications between the public Telecommunications network and the PBX performed centrally becomes. In this case, the allocation device (data base) part of a be intelligent network, so that the assignment via the intelligent network can be done on the ground. At the PBX on the plane However, you need a corresponding identifier (eg, Seat number) which the associated internal Communication terminal designated in the aircraft, also transferred to be so that the redirected call from the PBX to the This identifier corresponding internal phone can be forwarded.

In a preferred development of this embodiment is the Assignment means or the radio base station in provided information Related reading device by means of Data from a person associated, in particular mobile, private Telecommunications terminal can be read and / or the Call forwarding to internal communication terminal is triggered.

If an airline passenger at check-in will be assigned a seat, will also provide information on the mobile phone of flight passenger queried and together with the seat number in the Allocator stored. This can be done automatically, wherein this information should be stored separately so that no Problems with other data of airline occur. On a Such separate allocator can then transferred to a destination Call access. If present in the plane internal Phones are each addressed seated dependent, a diverted call based on the co-assigned seat number already clearly on the corresponding internal phone are forwarded on the plane.

Particularly easily call forwarding and assigning a make internal communication terminal device when the Reader is a card reader for a data carrier for the Use of a mobile, private telecommunications terminal is provided, and as a SIM card (SIM: Subscriber Identity Module) referred to as. Already at check-in which passengers can centrally appropriate registration or subscription perform by for example, the SIM card of their private mobile phone in the card reader for a Exchange of information, especially for the allocation of their personal Call to them on the plane each assigned internal Telephone, introduce.

If the allocator in information communication with the radio base station is, is a fixed seating dependent addressing the internal telephones an aircraft possible, so that the assignment of the personal numbers to the internal telephones in an Allocator can be done on the ground.

In an alternative embodiment, the assigning means is however, with the PBX in information link, so that using the mitübermittelten personal number only in the plane takes place allocated to the internal telephone.

Finally, the invention includes also a Telecommunications network for passenger transport companies, particularly for aircraft / ship or railroads comprising a as described above, preferably not public Telecommunication system and at least two each in a Passenger vehicle (aircraft) provided PBXs, each having its own special telephone number of a particular assigned to the public telecommunications network. With help of a such telecommunication network can to special numbers forwarded calls the public telecommunication network respectively at forwarded the corresponding PBX in each plane will.

Further advantages of the invention will be apparent from the description and the Drawings. Also, the above-mentioned and yet further characteristics listed according to the invention either individually find or together in any combination. The shown and described is as exhaustive understand enumeration but has exemplary character for describing the invention.

The invention is illustrated in the following drawings and will be based an exemplary embodiment explained:<dl tsize="6"><dt>Fig. 1</dt><dd>schematically shows an inventive Telecommunication system using the example of an aircraft, and</dd><dt>FIG. 2</dt><dd>shows the flow chart for an inventive method for establishing a telecommunication connection in the Telecommunications system.</dd></dl>

An illustrated in Fig. 1 plane 1 is provided with a plurality of internal Communication terminals equipped in the form of telephones, of which only represented by the reference numerals 2 and 3 show two exemplary are. Preferably at each aircraft seat such internal Communication terminal. All internal Communication terminals 2, 3 are connected to a PBX 4 connected and operated solely by this. The Communication link 5, 6 between the PBX and 4 their internal communication terminals 2, 3, or wirelessly take place via connecting lines. The PBX 4 is a PBX and an arranged Airborne 1 transmit / receive unit 7, via which using a satellite 8 Radio signals with an on-ground radio base station 9 can be exchanged.

A furnished by the airline special number "XY747" is of air passengers, the participants of a public telecommunications network PSTN 10 (PSTN = Public Switched Telecommunications Network), or the subscriber of a mobile network 11, such as GSM (Global System for Mobile communication), are, as a forwarding number used for their private telecommunications terminal 12. 13 These Special number "XY747" is the same for all passengers of the aircraft. 1

In private telecommunications terminal equipment may be for example, stationary phones 12 or involve mobile phones. 13 In this For the person (participants) B has a private mobile radio terminal and is in the mobile network 11 under his personal phone number accessible (arrow 15). The person C is a participant of the public Telkommunikationsnetzes 10 and has a conventional Telefonanchluß, which is assigned a number. The subscriber C is under this number reached (arrow 14). Are the people (Participants) outside their telecommunications networks, as they should yet still be accessible. For example, there are B and C as Passengers on the seats the no. 2 or 3 on board the aircraft 1, the special number "XY747" was assigned.

If now a private telecommunications terminal equipment, including the Mobile telephone 13 of the subscriber B with his personal phone number called, this call is 15 together with the personal treated as a phone number diverted call 1 7 and under the Special number "XY747" directed to a radio base station 18, which here a service control point SCP (Service Control Point) of an IN-network 20 represents. Using an in information communication with the radio base station 18 standing assignment device 19, in which the assignment the personal number of the subscriber (passenger flights) to him Airborne 1 seat assigned is stored, is based on the coassigned personal telephone number the assigned Seat number determined. This seat number (ID) is in a transmittable number (routing number) and reacted with the call to a service switching point (Service Switching Point) SSP in the IN network 20 passed. From there the call via the radio base station 9, the Satellite 8 and installed on a plane transmitting / receiving unit 7 at the local PBX 4 passed, in turn, the call according to co-assigned seat number to this Seat located internal communication terminal 2 forwards.

With the radio base station 18 shown in FIG. 1, there is also an Reading means 21 in connection information, by means of the check a flight passenger data to its mobile private Telecommunications terminal device 13 can be read. These Data are combined with the assigned flight passenger Seat number automatically stored in the allocator 19th

Instead of a ground-based allocator 19, the Assignment also provided for in the airplane 1 Assigning means 19 'occur, the information in the compound with PBX 4, and in the assignment of the personal Phone numbers stored on the respective seats. Based on personal phone number that together with the call to the PBX 4 is passed, then takes place by accessing the Allocator 19 'forwarding to the personal Number assigned to internal communication terminal. 2

The inventive method will now reference to Fig. 2 in more detail described, on Fig 1 by reference.: The Figure 2 shows the flowchart of method 100 in which, in a the first step 110 the subscriber B's personal phone number is assigned. If the participants in the supply area of staying mobile radio system 11, it is always available at this telephone number.

However, the subscriber is now as a passenger on board the in Fig. 1 shown aircraft 1. Therefore, in a next step 120 Call received at the mobile switching center to the Airborne installed PBX 4 diverted.

Then, in a step 130, the assignment of the personal Phone number to the phone board 2 of the participant in the Allocator 19 stored.

This assignment is the Eingan the call in a step 140 the terminal, namely the board phone 2, determined. The calling then from the Nebestelenanlage 4 of this board phone 2 next passed.
