Definitions

  • the invention relates to a method and an arrangement for retrieving data.
  • Data retrieval is known from the use of a computer network, e.g. the internet. Due to the abundance of data in the computer network, the search for the actually interesting and relevant data is usually extremely difficult. In particular, if the user does not know the actual filter during the search, it is difficult for him to obtain a suitable search result.
  • the object of the invention is to provide a possibility for data retrieval, where location information helps with a specific query of the data, a user not necessarily having to know the corresponding location information.
  • a method for data retrieval in which a first computer is coupled to a second computer via a communication link. Location information of the second computer is determined. The second computer uses the second computer to call up data which are relevant with regard to the location information.
  • the first computer can serve as a data server that keeps the location-related data available to the second computer.
  • a location of the second can automatically Computer are determined and this location is communicated to the first computer in the request of the second computer based on a location attribute.
  • the evaluation of the location on the first computer means that the result of the query, that is to say the data transmitted to the second computer, is relevant to the second computer with regard to its location information.
  • the location information can also be specified. Relevant location information can thus already be called up for a location of interest without the second computer actually having to be located at this location.
  • the location information can be in a computer network consisting of several first computers, e.g. the Internet, or specifically requested from a very specific first computer (data server).
  • the location information can be determined in particular via a satellite navigation system (Global Positioning System, GPS) or a cell-oriented communication network (e.g. DECT or GSM radio network).
  • a satellite navigation system Global Positioning System, GPS
  • a cell-oriented communication network e.g. DECT or GSM radio network.
  • the second computer is a mobile unit, in particular in a vehicle. If the second computer is in motion, the retrieved data can be dynamically adapted to changing location information. E.g. it is possible to determine the current location of the second computer at predetermined times and to send a query to the first computer with this location information. The retrieved data can update the previously retrieved data.
  • Users can be offered numerous regional services without having to worry about their position.
  • information about regional events, the traffic situation around the user or tourist information about nearby cities and / or sights can be kept ready. In particular, it should be pointed out that the user does not even have to know his whereabouts and is nevertheless offered the nearest destinations.
  • the query is not limited to a special service, but can, enriched with the attribute of
  • Location information, cross-network and / or cross-service On the one hand, a search on the Internet based on the location information can provide the desired information regarding nearby sights, but the traffic information can be retrieved from a central traffic computer (the attribute of the location information being used as a filter for the flood) possible information serves).
  • Relative location within a radio network, e.g. m a cluster of a DECT or GSM network;
  • Predefined no automatic location determination depending on the actual location of the second computer, but specification of the desired location for use as a targeted filter (attribute: location information at Query in the computer network and / or with a single data server).
  • determining the location it makes sense to call up the data from the first computer that has a predetermined distance from the location information determined on the second computer with regard to a desired filter (for example hotels), for example: "All hotels are at a distance of five kilometers from the current position ".
  • a search can be initiated via a suitable interface on the first computer and / or a computer network of several first computers.
  • the result of the search is displayed to the user on the second computer.
  • There he can further specify the search if necessary or request additional information about the data found.
  • the combination of several search services ensures a particularly satisfactory result in practice.
  • the second computer can have a program that processes independently retrieved data and / or initiates suitable queries with one or more computers and presents the processed result to the user.
  • the logic of the search engine m moves to the second computer.
  • a combination of logic in the second computer and logic in the first computer can lead to a particularly good search result.
  • the mobile unit can be in particular:
  • a mobile computer e.g. a PDA (Personal Digital Assistant), a notebook or a radio telephone with an extended range of functions;
  • a navigation computer in a vehicle e.g. a PDA (Personal Digital Assistant), a notebook or a radio telephone with an extended range of functions;
  • a navigation computer in a vehicle e.g. a PDA (Personal Digital Assistant), a notebook or a radio telephone with an extended range of functions;
  • the retrieved data has local information (additional location information) that is used to determine a path from the location information to the local information.
  • An example is the search for a cinema closest to the current location information.
  • the data retrieved provides the nearest cinema with address.
  • the route can be determined automatically by the
  • Location information is used as a starting point and the local information as a destination. Now, for example, a shortest or a fastest route can be determined using a navigation system.
  • the local information is determined indirectly on the basis of the data retrieved.
  • the data retrieved could include a user group. If the addresses of these users are not included in the retrieved data, they can be queried via an address database (e.g. by searching for names). Once the address has been found, the current location information can serve as the starting point and the determined address of a user in the group can serve as the destination for a route determination.
  • the route is preferably determined dynamically, since the position of the second computer (and thus the location information) can change at predetermined times.
  • an arrangement for retrieving data is also given: a) in which a first computer is coupled to a second computer via a communication link; b) in which location information of the second computer can be determined; c) in which, based on the second computer, data which are relevant with regard to the location information can be called up by the first computer.
  • Fig.l is a sketch showing a block diagram with computers for data retrieval
  • FIG. 2 shows a processor unit which can be used as a first computer or as a second computer.
  • the mobile computer 101 (second computer in the above embodiments) calls data from at least one first computer (m FIG. 1 computer 102 or computer network 103 with the computers 104, 105 and 106) via a radio interface or a landline connection (see connections 107 and 108) from.
  • the data are relevant with regard to location information determined by the mobile computer 101 (see attributes 109 and 110).
  • the computers (102 or 104 to 106) deliver data which have a certain relevance with regard to the location information.
  • the location information is determined automatically by the mobile computer 101: the position can be determined absolutely by means of satellite navigation, the position becomes relative
  • the Location information can be specified manually.
  • the location information is taken into account transparently on the computers 102 or 104 to 106, ie the "location information" attribute is used by the mobile computer when querying as a special filter. How the attribute was assigned a value is irrelevant for the computers 102, 104, 105 and 106 (transparent service).

  • Memory SPE and an input / output interface IOS which is used in different ways via an interface IFC: output is displayed on a monitor MON and / or output on a printer PRT via a graphic interface. An entry is made using a mouse MAS or a keyboard TAST.
  • the processor unit PRZE also has a data bus BUS, which ensures the connection of a memory MEM, the processor CPU and the input / output interface IOS. Furthermore, additional components can be connected to the data bus BUS, e.g. additional memory, data storage (hard disk) or scanner.
