Method for call number allocation and device for carrying out the method

0001The invention relates to a method for call allocation, a terminal and a Communications center.

0002To the owner of a terminal, in particular a terminal for a motor vehicle, a call to a special phone number, in particular a possible to enable rapid emergency etc., the terminal is equipped with a Notruffunkion will. Useful mobile devices can be realized in particular through mobile. However, a call from a terminal is only possible in mobile networks when the terminal in the network is known, so for example, a mobile phone contract for the finished terminal and this is allocated to a mobile number. The administration, in particular the accounting and correspondence, etc. for the mobile telephone network participating terminal is very complicated; exceed the administrative costs revenue from charges in a rare for a single terminal call the Vehicle at a (possibly of several) target number, such as an emergency number.

0003The object of the invention is, therefore enabling the call to a destination number from a predetermined set of target numbers, in particular an emergency number by a terminal under optimization of mobile network other costs incurred. The task is solved by the subject matters of the independent claims.

0004The inventive method can be a terminal predetermined destination numbers, especially emergency numbers to call, without, for example, through a mobile phone contract and an associated terminal phone number in the communication network, in particular to mobile network, to be identified. The fact that the terminal of the call the predetermined target numbers a caller number from a predetermined group cation network possible by the terminal. Here are appropriately reserved Caller numbers only for terminals without identification in the communication network, especially for emergency uses. It is also the use of the method for (eg rare) supplying traffic data (FCD) of a vehicle to a traffic center to a specific target number possible. Also, a recovery the method of toll accounts with Toll-destination number possible. After a Call a terminal at a target number, the him temporarily Assigned unlocked caller number again for a call of a terminal at a destination number will.

0005The selection of the target numbers from the predetermined set of target numbers, in particular an emergency number, by the terminal can to a manual input, particularly pressing an emergency button, to be carried out. this makes possible a rapid alert in the event of an accident or the like, with call due to a pressed emergency button etc. Entering an emergency telephone number is saved. Further, it is possible to generate the trigger signal automatically, in particular by operated in an accident sensors, such as acceleration and / or Strain sensors, which permits a particularly rapid assistance in the event of Accident and allows also a call allows even when due the accident, the parties are no longer able, even with a target number, especially emergency number to call.

0006The target number expediently contains the number of an emergency call center. Moreover contains the target number expediently the position of the destination number calling terminal. This is at least approximately the location of the terminal and automates thus quickly and accurately detected and processed further, for example in an emergency call center. The position of the terminal in the destination number is expediently in the form of its longitude and latitude, especially after the number an emergency call center, received; by the emergency call center and the terminal standardized rounding, ie by the transmission of the longitude and width, each with a predetermined number of digits are the longitude and width very easily automated weiterbearbeitbar; Moreover, in terminals, which also used for navigation or traffic detection and traffic information are, in part, the terminal position in the form of latitude and Width of a positioning device, in particular GPS, known. Further it is expedient if the called destination number in addition to the number of PSAP and possibly the position terminal a time value on the date contains the call of the terminal at the destination number; Therefore, the terminal suitably a time recording device, so watch or clock, on whose Time information for generating corresponding digits of the called destination number is used. So is also the time of an accident in which the automated Target number assigned to users, in particular an emergency call center, weiterbearbeitbar. The transmission of the terminal position and / or the timing of the call the terminal at a destination number in the form of the statement at certain positions the target number has the advantage that these data without receiving a phone full connection when the target number assigned to users, in particular a Notrutzentrale, can be further processed.

0007When the terminal receives an acknowledgment of his call, is an information of Terminal owner on the successful call possible, particularly in the case is an accident expedient.

0008Further features and advantages will be apparent from the following description an embodiment with reference to the drawing. In which:<dl tsize="7"><dt>Fig. 1</dt><dd>schematically the call of a motor vehicle at a target number via a mobile network,</dd><dt>FIG. 2</dt><dd>as a flowchart roughly the expiry of a call and its processing.</dd></dl>

00091 shows on a road locomotive vehicles 1 to 4 with built Mobile radios, each with associated mobile numbers (0172-1 to 0172-4) and a vehicle 5 with a terminal according to the invention without their own mobile number and a telecommunication center 6 of a communication network, here a cellular network and an emergency call center. 7

0010The terminal 8 in the vehicle 5 to call a Determine target number. The target number may be a number, for example, when a vehicle FCD data as its Speed ​​and / or position etc. sends to a traffic control center. It can for example also be a number for toll detections. In the event of an accident of the vehicle 5 can this particular phone number 117 may be an emergency call center. 7 Such a call can manually by pressing an emergency Faste or sensors in the vehicle, in particular acceleration and / or deformation sensors in Event of an accident, etc., are triggered. The call of the terminal 8 in the vehicle 5 via an antenna 9 of the vehicle via radio 10 in a customary for mobile devices Way through a telecommunication center 6 of the communication network in an emergency call center. 7

0011In the telecommunication center 6 of the communication network are the numbers of identified devices, such as mobile phone numbers of the terminals of the vehicles 1 to 4 is stored as the caller numbers; the devices in the vehicles ie 1 to 4 have, for example, mobile phone contracts and own assigned Mobile caller numbers. In addition to an Excellent communications, mobile network here, characterizing caller number (0172, etc.) have the terminals own, they identifying caller numbers. This caller numbers 1 to 4, etc. are in the Central communication stored in a memory 11 as numbers of identified Terminals. However, the terminal 8 in the motor vehicle 5 is in the central communication unit the communication network not as a participant with a contract and a caller number stored. The allocation of own caller numbers only for rare calls specific target numbers, especially emergency numbers used, Terminals 8 would also be of administrative, especially accounting reasons, to expensive. Therefore, in the case of a call of the terminal 8 in the telecommunication center 6 of the communication network to the terminal for the duration his call at a destination number from a predetermined set of target numbers, in particular an emergency number (117) an emergency call center 7, a caller number x₁ from a predetermined group of 12 reserved for this purpose caller numbers x₁, x₂etc. allocated. After completion of the communication between the terminal and the Target number, especially emergency center number (117), the temporarily the terminal assigned caller number re-released for another call from a not in the central communication unit 6 of the communication network identifed terminal.

0012In the central communication unit 6ES communications network is here before awarding a caller number x₁, x₂ etc. from the group of 12 reserved for this purpose caller numbers examined whether the called terminal from the destination number (117) of the emergency center contained 7 etc. in the predetermined group of 13 target numbers (117, etc.). If it is included, the call of the terminal 8 is at the target number or their early identifed participants passed the PSAP 7 here 25th In the emergency call center 7 can take in addition to their number (117) in the target number forwarded number components are evaluated. In particular, the present case, the terminal position determination device, namely here a GPS unit, to. The thus determined position is in addition to the number (117) the emergency call center 7 in the called total target number 14 from the terminal 8 to the telecommunication center and 6 of this further to the PSAP 7 received. The position may, in particular rounded in the form of geographical Length and width of a communication network number (recordable as 0172 in a mobile network) and the destination number (117) of the emergency call center 7 are transferred. For this purpose, the terminal that retained by the positioning device and rounded position l₁, l₂, l₃, l₄, b₁, b₂, b₃, b₄ appended to the number. In headquarters and in the terminal 8 is standardized as, in particular, at what position and at what length, the position is transmitted to the total target number 14th This is quick and error-free position determination of the terminal 8 and thus an accident etc. possible.

0013Further, the called total target number included 14 other data. Especially can an indication t₁, t₂, t₃, t₄ on the time of the call of the terminal at contain a target number. This is standardized in the terminal and at the headquarters. You can, for example, by a time detecting unit in the terminal 8 to Formation of corresponding points are used in the total target number 14th The Transmission of data as a virtual phone number ingredients has the advantage that this data via the communications network to the subscriber with the destination number (117) be transferred and automatically there and thus for example even without building a solid compound evaluated between the terminal and the subscriber with the destination number are. Especially when in the total target number 14 is also a reason the call, such as "accident" or the like., defining that in the terminal and in PSAP same standardized code is transmitted, is a preferred treatment certain calls possible. Moreover, the call answer can such without waiting for busy, tangled in a long communication subscriber the destination number (117) with other terminals, be delayed. In the emergency center 7 a destination number processing device is provided. This detects transmitted additional portions of the total target number 14, in particular place and / or time and / or other (the "accident"), evaluates them and initiates appropriate measures in particular the sending of emergency vehicles to the specified location.

0014Figure 2 is a flowchart showing the flow of a call and its further processing. After an accident in (step 15) and its detection or manual Input in step 16 is generated, the total target number 14 in step 17, which possibly a communication network number (0172, etc.), the target number (117) an emergency call center, as found in the terminal from a positioning device geographical Position in a defined format l₁, l₂, l₃, l₄, b₂, b₃, b₄The time t₁, t₂, t₃, t₄ (two Ask for the hour, two digits for the minute, etc.) and other data (here: "Accident") comprises. In step 18 it is checked and determined in the fixed network, that the called Destination number or the part 117 of the total target number 14, a number is selected from the group given target numbers. Since the terminal 8 does not own has number in the communication network, it is in step 19 for the duration of the call a temporary caller number x₁ reserved from a given group 12 Caller numbers x₁, x₂ etc. assigned and in step 20, the call to the destination number with the other components l₁ to "accident" of the total target number 14 received .. Here, a full connection are recorded or it can instead only the transmitted by the total target number 14 Data l₁ to "accident" automatically be evaluated. Also takes place in an acknowledgment of the call to the terminal 8 where this acknowledgment for example, by an output device, such as a Warning can be issued etc.. In step 21, according to the communication between terminal 8 and the emergency call center 7 to the target number that the terminal 8 assigned caller number x₁ enabled again for the next call a Terminal.
