Each radio cell contains a fixed radio station F 1 , F 2 , ..., and mobile radio stations M 1 , M 2 , ... move within the radio cells.

Die ortsfesten Funkstationen F 1, F 2 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 F 1 , F 2 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 M 1, M 2, ... 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 M 1, M 2, ... hat eine Sende-Empfangsantenne 26, 27. Die Informationsspeicher 20, 21 der mobilen Funkstationen sind vor­ zugsweise Bestandteil eines Mikroprozessors oder Mikrocomputers des Funktelefons. Each mobile radio station M 1 , M 2 , ... 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 M 1 , M 2 , ... 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 the following.

Zwischen den ortsfesten Funkstationen F 1, F 2, ... und den mobilen Funk­ stationen M 1, M 2, ... werden Informationen ausgetauscht, wie zum Bei­ spiel die individuellen Feststationsnummern der ortsfesten Funkstationen F 1, F 2, ..., 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 M 1, M 2, ... eine Standortinformation, die dem ungefähren Aufenthaltsort der jeweiligen mobilen Funkstation ent­ spricht. In dem optischen oder elektronischen Kartenspeicher 22, 23 der mobilen Funkstationen sind die Kartenausschnitte des von der mobilen Funk­ station 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 Aufenthalts­ orten und zugehörigen Kartenausschnitten herstellt. Vorzugsweise beim Ein­ schalten einer mobilen Funkstation, zum Beispiel M 1, 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 F 1 , F 2 , ... and the mobile radio stations M 1 , M 2 , ..., such as the individual fixed station numbers of the fixed radio stations F 1 , F 2 , ... , as well as field strength and / or transit time information (depending on the radio network).

Determine location information that 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 locations and associated map sections. Preferably, when a mobile radio station, for example M 1 , is switched on, the location information characterizing the approximate location is read out from the information memory 20 , the associated map section is automatically searched out on the basis of 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 F 2, empfängt. Jede neue, sich von der gespeicherten Information unterscheidende Information, die das Empfangsteil der mobilen Funkstation M 1 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 searched out when the mobile radio station receives the base station number of another fixed radio station, for example F 2 . Any new information, different from the stored information, which the receiving part of the mobile radio station M 1 receives, overwrites the previously stored information in the information memory 20 .
