Definitions

  • the invention relates to a cordless telephone system with cell-providing base stations located at geographically different locations and with mobile parts which are set up to establish a connection within the radio cell of a base station.
  • the object on which the invention is based is to make it easier for people, in particular travelers who are unfamiliar with the location, to reach a specific destination.
  • Comfortable solutions for this task are to rent a taxi with a local driver or a rental car with a satellite navigation system. These solutions are too expensive for the majority of travelers.
  • the cost-effective solutions namely to find the destination and a route using timetables and city maps, are again the most inconvenient and require a considerable amount of time.
  • the invention achieves the present object, starting from a cordless telephone system of the type mentioned at the outset, in that at least several of the base stations are assigned at least one central computer which is used for processing geographic data and their assignment to traffic routes is set up so that the system is set up to transmit at least one geographic destination entered by a user via the base station to the central computer after establishing a connection between a handset and the central computer Determination of an expedient geographical connection between the position of the base station given by geographical coordinates and the transmitted destination, and for the transmission of a corresponding route information via the base station to the mobile part.
  • the invention enables an individual query of the travel route by any traveler who carries with him a suitable handset, for example borrowed on arrival in a city.
  • “geographical coordinates” are usually not understood to mean physical coordinates in the sense of a task of geographical longitude and latitude, but merely designations, for example of stations or places.
  • a useful embodiment is characterized in that the system is set up to transmit a list of geographical destinations to the handset after a connection has been established between a handset and a base station, which can be shown on a display of the handset. This gives the user a choice and he can then enter the selected destination, be it e.g. by voice or via the keyboard so that it is transmitted to the central computer.
  • a particularly convenient handling is achieved if at least one of the displayed destinations of the transmitted list can be provided with a marking with the aid of an input device and the at least one marked destination can be transmitted to the central computer via the base station.
  • An expedient development of the invention which also enables rapid processing, is characterized in that a coordinate register is provided which contains the geographical coordinates of the base stations and their identifications, and the central computer by comparing a received identification with the entries in the coordinate register for retrieval that is set up for the base station specific coordinates.
  • the geographic coordinates can also be stored in a memory of each base station, so that a comparison with the identification does not necessarily have to be made.
  • the list can be an alphabetical list of street and / or place names.
  • the route information is a sequence of street names and / or traffic lines with stations.
  • Another convenience is the user if the handsets have a built-in printer.
  • voice information from the central computer and / or a base station can be transmitted to a mobile part, since additional information can thus be transmitted to the user quickly.
  • the handset In order to be able to call up information in speech at any time and also outside of a radio cell, it is recommended that the handset has a speech memory for the transmitted speech information. In the interest of increased convenience of use, it may be appropriate for the user to be able to enter the geographic destinations in a voice-controlled manner.
  • FIG. 1 shows a cordless telephone system according to the invention in a schematic illustration
  • FIG. 2 shows a flow diagram of a possible connection processing.
  • Fig. 1 four radio cells FZ1 ... FZ4 are symbolized by circles or ellipses. These radio cells are formed by base stations FP1, FP2A, FP2B, FP3, FP4 of a cordless telephone system. These radio cells are installed at stations STA1 ... STA4, for example subway stations, airports, public places, etc. In this example it was assumed that the station STA2 has two base stations STA2A, STA2B to cover the station area and to form a correspondingly larger radio cell FZ2 due to the larger spatial extent.
  • Each STAL ... STA4 station has geographic coordinates or other variables within a city, in general an area, which serve to determine the location, for example on a map.
  • GK1 ... GK4 which are assigned to the stations STAl ... STA4.
  • each base station FP1 ... FP4 has a memory SPE for an identification ID of the device.
  • this memory SPE can also contain the geographic coordinates GK of the station STAL ... STA4, which, however, is not necessary for the function of the system described below.
  • All base stations FP1 ... FP4 are connected to at least one central computer ZRE, for example an additional computer from the local transport company, which contains all the necessary data about the city's traffic network or route network, which is required to determine the cheapest connection between two locations.
  • the central computer ZR contains a coordinate register GKR in which the geographic coordinates GKT. All stations STAi and the identifications ID_ of the base stations in a corresponding assignment to the geographic coordinates.
  • the base stations FP2A, FP2B of the station STA2 are assigned identical geographic coordinates, since these base stations cover a common radio cell FZ2.
  • the cordless telephone system naturally includes mobile parts which can establish a radio connection to base stations.

  • DECT Digital Enhanced Cordless Telecommunications
  • a relatively large-area display ANZ for example an LCD display
  • a small printer PRI is also built into the handset PP.
  • the function of the system according to the invention is explained below using an example of use. A person arriving in a city rents a PPx handset, for example at an airport tourist office.
  • the user of the PPx handset now switches the device on and sets, e.g. by a suitable key selection on the TAF key field, a connection to the base part, e.g. FPl, fro.
  • a connection to the base part e.g. FPl, fro.
  • each base station has its own identification, the so-called "Radio Fixed Part Identification” RFPI, which, for example is explained in more detail in the ETSI standard ETS 300 175-6, Sept. 1996.
  • the user can now, for example, press a button for establishing a connection, and the known “set-up” and “connect” information is exchanged between the handset and the base station.
  • a list of streets in the city or only part of such a list is then transmitted to the handset PPx, usually from the central computer ZRE, and is shown on the display ANZ.
  • the user can now "scroll” in this list, for example by pressing the up / down buttons.
  • corresponding information is "scrolled" to the base station and from this to the central computer ZR, and the next part of the list is forwarded to the handset PPx and shown on the display ANZ.
  • the user can now select a destination selected by him, for example a street or an underground / subway station, which is best done by marking the corresponding destination on the Display occurs.
  • a destination for example a street or an underground / subway station
  • the selected destination can be passed on as information "destination" to the base station or to the central computer ZR.
  • the above-mentioned process can also be carried out by entering a destination in alpha-numerical form.
  • the central computer ZR After the central computer ZR has received the desired destination, it transmits the most convenient route for the user, in this case e.g. from the airport to a hotel or subway station.
  • This route information WIF can now be stored in the handset PPx and simultaneously shown on the display ANZ or, if a printer PRI is available, can also be printed out on a paper strip as information WIF. This has the advantage that the user can then e.g. can be stowed in a pocket and only has to use the paper strip, which is insignificant in terms of weight, until it requests a route to a new destination via its PPx handset.

  • voice information especially from the central computer, in particular requests to enter certain information or to actuate certain keys.
  • a such voice information can help shorten the operating sequence considerably.

  • a corresponding voice evaluation which is switched on between the user and the central computer and is located, for example, in the central computer or in the base stations, it is also possible to have the entire information exchange controlled by voice.
  • the user can enter a desired destination when asked, for example, "Now clearly speak your destination into the microphone", e.g. "Südbahnhof".
  • the central computer can now transmit corresponding information in voice to the user via the base station, e.g. "Use bus line 13A and drive seven stops".
  • This information can optionally also be stored in a voice memory of the handset, so that the user can access it at any time, even after leaving the radio cell of the base station.
  • the combination "language display” is also possible and particularly useful in many cases.
