Definitions

  • the invention relates to a method for transmitting environmental information and a navigation method using this method.
  • the invention relates to a terminal, a navigation device and a mobile radio network base station for performing the method.
  • the cartographic information required for navigation is generally taken from a data memory of the device itself.
  • the data memory is often an exchangeable data memory, for example cards on CD-ROM.
  • the navigation device uses this map material to determine the optimal route between an entered location and a destination.
  • the current location of the vehicle is determined at any time via a location determination system, for example GPS, and a map section around the location is shown on a display, the location being marked within the map section.
  • the direction of travel to be taken is indicated by a corresponding voice output or by arrows on the display.
  • a disadvantage of this method is that the map material is not up to date.
  • this method should serve to provide the respective user with simple and inexpensive information, for example for navigation aid for pedestrians or the like.
  • the method should also only be usable for carrying out or optimizing navigation methods
  • environmental information relating to an area which is adapted to the cell belonging to the base station is stored for different base stations of a cellular mobile radio system.
  • the term “cell *” here means the transmission / reception range of the respective base station.
  • the cellular mobile radio system can be any mobile radio system, for example according to a GSM, UMTS or DECT standard.
  • the environmental information is preferably cartographic information. In principle, however, it can also be other environmental information, for example information about sights, leisure facilities or the like. Of course, it can also be a mixture of different information, i. H. act cartographic and additional information.
  • This environmental information is at least partially sent from the base station to a terminal located in the respective cell and output by the terminal.
  • the output can be made either directly to the user, for example by means of voice output or via a display. However, it can also be an output to other devices, for example to a motor vehicle navigation device connected via an interface.
  • the adjustment of the area available on the station for the respective base ⁇ information to the respective cell can be done so that the area of cover and the cell match the same.
  • the area is expediently somewhat larger than the corresponding cell, so that end devices which are located at the edge of the cell also receive information about their entire environment within a certain surrounding area and not only around a surrounding area in the direction of the respective base station who is currently connected.
  • the area is smaller than the respective cell, that is to say that no environmental information is made available for certain areas within the cell, for example.
  • cell therefore preferably includes the identical correspondence between cell and information area or a definition of the information area with a certain edge coverage outside the cell, in the broadest sense this term encompasses any adaptation to the cell, taking into account further parameters.
  • the environment information for the individual base stations can be stored centrally in a special facility in the mobile radio network and can be called up by the base stations as required. In order to minimize the data flow within the network, however, it makes sense if the environmental information is stored locally at the individual base stations.
  • Another alternative is to store the data in the so-called “base station controller * (BSC), which control several base stations (also called“ base transceiver station * (BTS) in the GSM system). This saves storage facilities and still reduces the data flow within the mobile radio system.

  • This correction data can be immediately transmitted with the environmental information.
  • a determination by the mobile radio system itself is also possible, for example by means of the “timing advance * method, in which information about the distance of the terminal from the base station or from different base stations of the mobile radio network is determined on the basis of the transit times.

Abstract

L'invention concerne un procédé pour la transmission d'informations relatives à l'environnement. Selon ce procédé, des informations relatives à une zone sont mémorisées pour différentes stations de base d'un système de radiotéléphonie mobile cellulaire, la zone étant adaptée à la cellule appartenant à la station de base. La station de base envoie au moins partiellement ces informations relatives à l'environnement à un terminal qui se trouve dans la cellule correspondante et qui les émet à son tour. Les informations relatives à l'environnement actuelles ainsi reçues peuvent être utilisées à l'intérieur d'un procédé de navigation.
