Description

Die Erfindung betrifft ein Ortungs- und Navigationssystem nach dem Oberbegriff des Anspruchs 1.The invention relates to a location and navigation system according to the preamble of claim 1.

Stand der TechnikState of the art

Es ist ein Ortungs- und Navigationssystem bekannt (Elektronik, 1987, Heft 20, Seite 30), das mit Kartenunterstützung arbeitet. Das System hat den Nachteil, daß der Fahrzeugführer aus einer Vielzahl von Kar­tenausschnitten den dem jeweiligen Aufenthaltsort des Kraftfahrzeuges entsprechenden Kartenausschnitt heraussuchen muß. Dabei können Fehler nicht ausgeschlossen werden. Außerdem stellt das Aussuchen des Karten­ausschnitts eine Belastung für den Fahrzeugführer dar.A location and navigation system is known (Elektronik, 1987, number 20, page 30) that works with map support. The system has the disadvantage that the vehicle driver has to look for the map section corresponding to the respective location of the motor vehicle from a large number of map sections. Errors cannot be excluded. In addition, the selection of the map section is a burden for the driver.

Es ist weiterhin ein Verfahren nach dem Oberbegriff des Anspruchs 1 vorgeschlagen worden (P 37 16 320.5), bei dem der Aufwand für das Be­stimmen des Aufenthaltsortes einer mobilen Funkstation in einem zellu­laren Funktelefonnetz dadurch verringert wird, daß die ortsfesten Funk­stationen ihre individuellen Feststationsnummern und gegebenenfalls auch Feldstärkeinformationen an die mobilen Funkstationen aussenden. In jeder mobilen Funkstation kann dann aus diesen Informationen eine den ungefähren Aufenthaltsort der mobilen Funkstation enthaltende Standort­information abgeleitet werden.A method according to the preamble of claim 1 has also been proposed (P 37 16 320.5), in which the effort for determining the location of a mobile radio station in a cellular radio telephone network is reduced by the fact that the fixed radio stations have their individual base station numbers and, if appropriate, also Send field strength information to the mobile radio stations. In each mobile radio station, location information containing the approximate location of the mobile radio station can then be derived from this information.

The advantages that can be achieved with the invention are, in particular, that the user of a mobile radio station no longer has to search for the relevant map section himself, but that this map section is automatically searched out with little technical effort.

Beschreibungdescription

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung anhand einer einzigen Figur dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing using a single figure and is described in more detail below.

Die Figur zeigt ein Blockschaltbild eines in Funkzellen Z1, Z2, Z3, ... aufgeteilten zellularen Funktelefonnetzes. Jede Funkzelle enthält eine ortsfeste Funkstation F1, F2, ..., und mobile Funkstationen M1, M2, ... bewegen sich innerhalb der Funkzellen.The figure shows a block diagram of a cellular radio telephone network divided into radio cells Z1, Z2, Z3,... Each radio cell contains a fixed radio station F1, F2, ..., and mobile radio stations M1, M2, ... move within the radio cells.

Die ortsfesten Funkstationen F1, F2 weisen je ein Sendeteil 10, 11, ein Empfangsteil 12, 13 und eine Sende-Empfangsantenne 14, 15 auf. Die ortsfesten Funkstationen können gegebenenfalls auch Relaisstationen sein.The fixed radio stations F1, F2 each have a transmitting part 10, 11, a receiving part 12, 13 and a transmitting / receiving antenna 14, 15. The fixed radio stations can optionally also be relay stations.

Jede mobile Funkstation M1, M2, ... weist ein zu einem Funktelefon gehörendes Sendeteil 16, 17 und ein Empfangsteil 18, 19 auf. Mit dem Empfangsteil ist ein Informationsspeicher 20, 21 und mit diesem ein optischer oder elektronischer Kartenspeicher 22, 23 verbunden, an den sich ein Display 24, 25 zum Anzeigen eines Kartenausschnitts anschließt. Jede mobile Funkstation Ml, M2, ... hat eine Sende-Empfangsantenne 26, 27. Die Informationsspeicher 20, 21 der mobilen Funkstationen sind vor­zugsweise Bestandteil eines Mikroprozessors oder Mikrocomputers des Funktelefons.Each mobile radio station M1, M2, ... has a transmitting part 16, 17 belonging to a radio telephone and a receiving part 18, 19. An information memory 20, 21 is connected to the receiving part and an optical or electronic card memory 22, 23 is connected to it, to which a display 24, 25 for displaying a map section is connected. Each mobile radio station M1, M2, ... has a transceiver antenna 26, 27. The information memories 20, 21 of the mobile radio stations are preferably part of a microprocessor or microcomputer of the radio telephone.

Die Wirkungsweise des vorstehend erläuterten Funktelefonnetzes ist folgende.The operation of the radio telephone network explained above is as follows.

Zwischen den ortsfesten Funkstationen F1, F2, ... und den mobilen Funk­stationen M1, M2, ... werden Informationen ausgetauscht, wie zum Bei­spiel die individuellen Feststationsnummern der ortsfesten Funkstationen F1, F2, ..., sowie Feldstärke- und/oder Laufzeitinformationen (je nach Funknetz). Diese Informationen werden in den Informationspeichern 20, 21 der mobilen Funkstationen gespeichert. Aus den gespeicherten Informationen ermitteln die mobilen Funkstationen M1, M2, ... eine Standortinformation, die dem ungefähren Aufenthaltsort der jeweiligen mobilen Funkstation ent­spricht. In dem optischen oder elektronischen Kartenspeicher 22, 23 der mobilen Funkstationen sind die Kartenausschnitte des von der mobilen Funk­station befahrenen Gebietes, zum Beispiel eines Landes, einzeln abrufbar gespeichert. Der Informationsspeicher 20, 21 ist nun so beschaffen, daß in ihm eine Tabelle abgelegt ist, die die Korrelation zwischen Aufenthalts­orten und zugehörigen Kartenausschnitten herstellt. Vorzugsweise beim Ein­schalten einer mobilen Funkstation, zum Beispiel M1, erfolgt das Auslesen der den ungefähren Aufenthaltsort kennzeichnenden Standortinformation aus dem Informationsspeicher 20, das automatische Heraussuchen des zugehörigen Kartenausschnitts anhand der gespeicherten Tabelle und das Anzeigen des betreffenden Kartenausschnitts auf dem Display 24.Information is exchanged between the fixed radio stations F1, F2, ... and the mobile radio stations M1, M2, ..., such as the individual base station numbers of the fixed radio stations F1, F2, ..., as well as field strength and / or runtime information (depending on the radio network). This information is stored in the information stores 20, 21 of the mobile radio stations. The mobile radio stations M1, M2,... Determine location information from the stored information, which corresponds to the approximate location of the respective mobile radio station. In the optical or electronic map memory 22, 23 of the mobile radio stations, the map sections of the area traveled by the mobile radio station, for example a country, are stored individually and can be called up. The information store 20, 21 is now such that a table is stored in it, which establishes the correlation between whereabouts and associated map sections. Preferably, when a mobile radio station, for example M1, is switched on, the location information characterizing the approximate location is read out of the information memory 20, the associated map section is automatically selected based on the stored table and the relevant map section is displayed on the display 24.

Anschließend kann während der Fahrt die Korrelation dauernd oder in festen Abständen überprüft werden. Ein neuer Kartenausschnitt wird vorzugsweise dann herausgesucht, wenn die mobile Funkstation die Feststationsnummer einer anderen ortsfesten Funkstation, zum Beispiel F2, empfängt. Jede neue, sich von der gespeicherten Information unterscheidende Information, die das Empfangsteil der mobilen Funkstation Ml empfängt, überschreibt in dem Informationsspeicher 20 die vorher gespeicherte Information.The correlation can then be checked continuously or at fixed intervals while driving. A new map section is preferably selected when the mobile radio station receives the base station number of another fixed radio station, for example F2. Any new information, different from the stored information, which the receiving part of the mobile radio station M1 receives, overwrites the previously stored information in the information memory 20.
