Definitions
- the invention relates to a method for the spatial assignment of location-related information and a terminal for performing the method.
- the terminal receiving this information is required to determine the location to which the information relates and to compare it with the location at which the terminal is located. It is problematic that the geographical positions of places are usually neither exactly nor uniquely determined, for example, places such as intersections, junctions, etc. are assigned in different maps, different geographical positions and updates of maps, etc., partly the geographical Change positions of places in the map or add new places, such as new branches.
- a conceivable method for the spatial allocation in a terminal of information relating to a location would be a normalized assignment of an identity number to significant locations, such as road sections, motorway exits, etc., wherein the information provider and the terminal have identical tables of identification numbers and assigned locations , Although this procedure is clear, it can not be continuously updated without administratively complex centralized maintenance. Furthermore, due to the abstract identification number assignment in a terminal-side old code table, a spatial assignment of information received from an information provider at least at a designated by a new identity number new location, such as a new motorway exit, not possible.
- places can be assigned names. In this case occurs on long roads, especially highways, the requirement of subdivision by additives, such as "between junction x and y", on.
- the requirement of subdivision by additives such as "between junction x and y"
- the exit neighboring towns problematic.
- the object of the invention is to provide an efficient method for the spatial allocation in a terminal of information relating to a location and which are transmitted by an information provider to the terminal.
- the object is solved by the independent claims.
- the method according to claim 1 is particularly useful for the transmission of traffic information. However, it is also suitable for other application examples.
- Transmitted geographical coordinates of the location to which information relates may be present, for example, in two-dimensional coordinate representation, in particular as the geographical length and latitude of the location.
- location coordinate data By additional location data designated
- Location characteristics of the location may include, in particular, the street class and street number of the location. Further, they may include one or more names of the place. Furthermore, they may include additional attributes of the location, such as the information as to whether it is at an intersection, junction, etc., on which lane and whether at the end, beginning or middle, etc.
- the location for the terminal is defined. Due to the Ortszusatzdatei, in particular the street class and the street number, can still be a plausibility check.
- the location can be further processed and / or output based on the location coordinate data or on the basis of further data stored in the reference file for this location coordinate data.
- the location to which the information provider's information relates can be determined from the location overhead data transmitted along with this information and its location coordinate data by searching that location overhead data in the terminal's reference file.
- the additional use of location overhead data thus increases the likelihood of proper spatial allocation of received information to a location in the terminal and also avoids errors when, for example, using updated maps or using other than previously used maps, the geographic coordinates of a particular location according to the updated or other maps at the information provider change or differ from another information provider, while in the terminal only location coordinates for a particular map version are present.
- the spatial assignment of information received in a terminal to the location to which it relates can be optimized by the type of location coordinate data and location auxiliary data transmitted to a terminal by information providers.
- location information includes the street class and street number of the location to which the received information relates, and / or the names of those locations; the additional location data also expediently have attributes of the location, such as the information as to whether there is an intersection or junction, to which lane they relate, beginning, end or middle of a lane etc.
- the location coordinate data identifies the location to which information relates, conveniently by an identification number representing the geographical coordinates of the location.
- an identification number representing the geographical coordinates of the location.
- the information, location coordinate data and location additional data are expediently transmitted in a predetermined format and / or predetermined order, preferably in both, from the information provider to the terminal, which facilitates automated processing in the terminal.
- an identification of those digital map of a traffic network to which the location coordinate data relate advantageous because so due to the location coordinates associated with this digital map in the terminal, the place is easier to identify.
- the method can be used for the transmission and spatial assignment of different information.
- information may be traffic information of a traffic information provider for a terminal that can be arranged in a vehicle.
- traffic information may be traffic information of a traffic information provider for a terminal that can be arranged in a vehicle.
- the method can also be used in particular for interactive navigation, in which an unambiguous identification of a navigation information relevant place, such as the current location of the vehicle, is of importance.
- the transmission of information from the information provider to the terminal can be done in different ways. In particular, it is possible to transmit the information with or without coding via radio, mobile radio, paging, etc.
- the information is expediently output to a user of the terminal. For this they can be further processed. Thus, due to location coordinate data and / or additional location data, possibly with further data transmitted or taken from the reference file, a message for the user can be generated. In particular, if the location of the terminal is known to it, filtering of the information regarding e.g. local relevance to the user possible, with only relevant data is output to the user of the terminal.
- a link of the location with the received information is possible; for example, the message "congestion on A3 between junction x and y" can be converted into "traffic jam in front of you at two kilometers distance with 30 km length".
- a correction of the reference file in the terminal and / or the information provider in case of divergences of transmitted location coordinate data of a location is possible due to the co-transmitted location additional data in the reference file location coordinate data.
- a single correction of the specific location is possible;
- the location coordinate data transmitted by the information provider to the terminal may be stored to a location in the terminal's reference file as location coordinate data of the location defined there by the location overhead data corresponding to the associated location overhead data.
- a terminal according to the invention has a reference file with at least one assignment of location coordinate data to location auxiliary data on.
- information shown in FIG. 2 transmitted together with location coordinate data and additional location data, is allocated spatially in accordance with the method illustrated abstractly in FIG.
- a traffic message illustrated by way of example in FIG. 2 comprises, in addition to the information (1,2) represented as “event” (1) and "30 km congestion” (2), location coordinate data 3 and location auxiliary data 4, 5 designated as GeoCode.
- Such a message is transmitted by an information provider, such as a traffic information center 6 via mobile, paging, radio, etc. 7 to a terminal 8.
- an information provider such as a traffic information center 6 via mobile, paging, radio, etc. 7 to a terminal 8.
- the traffic information 9 is spatially assigned to the location to which the information relates 1.2 due to a reference file 10 shown in FIG.
- the location coordinate data 3 called GeoCode can be used for this purpose. These are formed here by rounding and omitting low order digits to about 100 m accuracy from the geographic longitude 12 ° 34'99 "and latitude 56 ° 78'99" of the location to which the information relates (e.g., 12345678).
- the location to which the information 1,2 relates is uniquely determined and can for the relevance check of the information 1,2 and / or output with the information 1,2 to the user of the terminal 8 and / or navigation are used.
- the relevance check may e.g. only filter out the information that is of importance to the user due to his location, which is determinable on the basis of route determination and / or GPS, etc. For example, only information of the road on which the user is traveling with the terminal 8 and / or in the direction of travel roads and / or a certain spatial radius can be considered.
- the location additional data 4, 5 under the entry in the reference file 10 do not match the transmitted location coordinate data 3 with the location auxiliary data 4, 5 transmitted with these location coordinate data 3, an entry with this location auxiliary data 4, 5 is searched for in the reference file 10 and its location as the location to which the information 1,2 refers.
- attributes such as names, etc., of the location may be used for review.
- the attributes may also be used to supplement a message to be issued to a user of the terminal 8, for example by adding a name stored in the reference file in the terminal ("Departure Pasing") etc. of a location to that location information.
- a sequence of the test is shown in FIG.
- the location coordinate data 3 of the transmitted traffic message 9 in the terminal 8 in a reference file 10 are searched (12). If an entry is found here (13), it is checked for consistency and plausibility (14) by comparing the additional location data 4, 5 in the received traffic message 9 and in the reference file 10 in the terminal 8. If the location overhead data 4, 5 match, the location coordinate data 3 is defined as consolidated georeference 15 and considered as location 16 to which the information 1,2 refers. If, however, there is no entry for the location coordinate data 3 of the traffic message 9 (17), the location is determined on the basis of the location additional data 4, 5.
- This may in particular be the road class 4 (eg "highway” or “A”) and the road number 5 (eg "8").
- the road class ("A") and the road number can also be communicated together in one field ("A8")
- Attributes such as the name (“Stachus” or “Karlsplatz” or “Departure Pasing"), are determined for the obtained information 1,2 and with this can be output to a user (as description 19).
- information 1,2 regarded as relevant on the basis of the location etc. can be output to a user of the terminal 8 with or without attributes.
- location coordinate data 3 and additional location data 4,5 and / or possibly also attributes 11 in the traffic message 9 and in the reference file 10 do not match, e.g. this error in the reference file 10 of the terminal 9 are automatically corrected or a new reference file 10, for example via mobile phone or otherwise, are loaded from the information provider to the terminal.
- the method according to the invention is also particularly suitable for navigation, since this is as accurate and error-free as possible localization is of great importance.
- the method is implemented in a program which is stored in the terminal. Furthermore, in particular for navigation methods, a map file can be used in the method and stored in the terminal.
- a reference file can be stored in the terminal; a reference file can also be stored on an exchangeable storage medium, such as a smart card or the like, wherein data from the memory can be read by a reading device in the terminal.
- a processor is provided there.
- the information provider's information is received in the terminal in a receiving device for radio and / or mobile radio and / or pagers, etc.
- the output of possibly revised or supplemented information 1,2 etc. to a user of the terminal via an example acoustic or optical output device.
- a return channel in particular the uplink of a mobile radio channel, can be provided for error correction or the download of a current reference file 10 into the terminal.
- the terminal is particularly suitable for installation in a vehicle. For determining the position, it may include, for example, a GPS receiver and / or a position determination by an internal map, the steering wheel position and odometer and / or speed counter, etc.
Abstract
Description
Die Erfindung betrifft ein Verfahren zur räumlichen Zuordnung von auf einen Ort bezogenen Informationen und ein Endgerät zur Durchführung des Verfahrens.The invention relates to a method for the spatial assignment of location-related information and a terminal for performing the method.
Zur automatischen Auswertung ortsbezogener Informationen, wie beispielsweise Verkehrsinformationen, ist im diese Informationen empfangenden Endgerät die Ermittlung des Ortes, auf welchen sich die Informationen beziehen, und ein Abgleich mit dem Ort, an welchem sich das Endgerät befindet, erforderlich. Dabei ist problematisch, daß die geographischen Positionen von Orten in der Regel weder genau noch eindeutig bestimmt sind, da beispielsweise Orten, wie Straßenkreuzungen, Abzweigungen etc. in unterschiedlichen Karten, unterschiedliche geographische Positionen zugeordnet sind und bei Aktualisierungen von Karten etc. sich teilweise die geographischen Positionen von Orten in der Karte ändern oder neue Orte, wie neue Abzweigungen, hinzukommen.For the automatic evaluation of location-related information, such as traffic information, the terminal receiving this information is required to determine the location to which the information relates and to compare it with the location at which the terminal is located. It is problematic that the geographical positions of places are usually neither exactly nor uniquely determined, for example, places such as intersections, junctions, etc. are assigned in different maps, different geographical positions and updates of maps, etc., partly the geographical Change positions of places in the map or add new places, such as new branches.
Ein denkbares Verfahren zur räumlichen Zuordnung in einem Endgerät von Informationen, die sich auf einen Ort beziehen, wäre eine normierte Vergabe einer Identitätsnummer zu bedeutenden Orten, wie Straßenabschnitten, Autobahnabfahrten etc., wobei beim Informationsanbieter und im Endgerät identische Tabellen von Identifikationsnummem und zugeordneten Orten vorliegen. Dieses Verfahren ist zwar eindeutig, jedoch ohne administrativ aufwendige zentrale Pflege nicht laufend aktualisierbar. Femer ist aufgrund der abstrakten Identitätsnummernvergabe bei einer endgerätseitigen alten Code-Tabelle eine räumlich Zuordnung einer von einem Informationsanbieter empfangenen Information zumindest bei einem durch eine neue Identitätsnummer bezeichneten neuen Ort, wie einer neuen Autobahnabfahrt, nicht möglich.A conceivable method for the spatial allocation in a terminal of information relating to a location would be a normalized assignment of an identity number to significant locations, such as road sections, motorway exits, etc., wherein the information provider and the terminal have identical tables of identification numbers and assigned locations , Although this procedure is clear, it can not be continuously updated without administratively complex centralized maintenance. Furthermore, due to the abstract identification number assignment in a terminal-side old code table, a spatial assignment of information received from an information provider at least at a designated by a new identity number new location, such as a new motorway exit, not possible.
In einem anderen vorstellbaren Verfahren können Orten Namen zugewiesen werden. Dabei tritt bei langen Straßen, insbesondere Autobahnen, das Erfordernis der Unterteilung durch Zusätze, wie beispielsweise "zwischen Anschlußstelle x und y", auf. Hinsichtlich einer automatischen Auswertung von von einem Informationanbieter an ein Endgerät übermittelten Informationen sind unterschiedliche Schreibweisen, beispielsweise Umlaute und Abkürzungen, sowie unterschiedliche Bezeichnungen, wie Stachus bzw. Karlsplatz in München, sowie die uneinheitliche Bezeichnung von Ausfahrten etc. durch der Ausfahrt benachbarte Ortschaften problematisch.In another conceivable method, places can be assigned names. In this case occurs on long roads, especially highways, the requirement of subdivision by additives, such as "between junction x and y", on. With regard to an automatic evaluation of information transmitted by an information provider to a terminal are different spellings, such as umlauts and abbreviations, and different names, such as Stachus or Karlsplatz in Munich, and the inconsistent designation of exits, etc. by the exit neighboring towns problematic.
Möglich ist ferner die Zuordnung eines Ortes durch geographische Koordinaten, wie geographische Längen- und Breitengrade eines Ortes. Jedoch tritt hier das Problem auf, daß derselbe Ort, beispielsweise eine Straßenkreuzung, in unterschiedlichen Karten an unterschiedlichen Positionen liegt, was problematisch ist, wenn die Verkehrsinformationszentrale Daten erhält, welche sich auf unterschiedliche Karten beziehen, oder wenn sich aufgrund einer Aktualisierung einer Karte die geographischen Koordinaten eines Ortes in der Karte ändern. Bereits bei relativ geringen Ungenauigkeiten der Angabe der geographischen Koordinaten eines Ortes ist dieser in einem Endgerät nicht mehr eindeutig zuordenbar. Eine eindeutige Zuordnung von Orten zu genormten geographischen Koordinaten würde jedoch einen hohen administrativen Aufwand bei der Definition und der Pflege nach sich ziehen.It is also possible to assign a place by geographical coordinates, such as latitude and longitude of a place. However, the problem arises here that the same location, for example a street intersection, is in different maps in different positions, which is problematic when the traffic information center receives data relating to different maps, or if due to updating a map the geographical Change coordinates of a place in the map. Already with relatively small inaccuracies of specifying the geographic coordinates of a place that is no longer uniquely assignable in a terminal. A clear assignment of places to standardized geographic coordinates, however, would entail a high administrative effort in the definition and the care.
"Verkehrsfunk digital: traffic message channel" aus "
Aufgabe der Erfindung ist die Schaffung eines effizienten Verfahrens zur räumlichen Zuordnung in einem Endgerät von Informationen, die sich auf einen Ort beziehen und die von einem Informationsanbieter an das Endgerät übermittelt werden. Die Aufgabe wird durch die unabhängigen Ansprüche gelöst.The object of the invention is to provide an efficient method for the spatial allocation in a terminal of information relating to a location and which are transmitted by an information provider to the terminal. The object is solved by the independent claims.
Das Verfahren nach Anspruch 1 ist insbesondere zur Übertragung von Verkehrsinformationen verwendbar. Es ist jedoch auch für andere Anwendungsbeispiele geeignet.The method according to
Übermittelte durch Ortskoordinatendaten repräsentierte geographische Koordinaten des Ortes, auf welchen sich Informationen beziehen, können beispielsweise in zweidimensionaler Koordinatendarstellung, insbesondere als geographische Länge und Breite des Ortes, vorliegen. Durch Ortszusatzdaten bezeichneteTransmitted geographical coordinates of the location to which information relates, represented by location coordinate data, may be present, for example, in two-dimensional coordinate representation, in particular as the geographical length and latitude of the location. By additional location data designated
Ortseigenschaften des Ortes können insbesondere die Straßenklasse und Straßennummer des Ortes umfassen. Ferner können sie einen oder mehrere Namen des Ortes beinhalten. Des weiteren können sie zusätzliche Attribute des Ortes umfassen, wie beispielsweise die Information, ob er an einer Kreuzung, Abzweigung etc. liegt, auf welcher Fahrbahn und ob an deren Ende, Anfang oder Mitte er liegt etc..Location characteristics of the location may include, in particular, the street class and street number of the location. Further, they may include one or more names of the place. Furthermore, they may include additional attributes of the location, such as the information as to whether it is at an intersection, junction, etc., on which lane and whether at the end, beginning or middle, etc.
Wenn zu von einem Informationsanbieter an ein Endgerät übermittelten Informationen mitübermittelte Ortskoordinatendaten in einer Referenzdatei im Endgerät enthalten sind, ist der Ort für das Endgerät definiert. Aufgrund der Ortszusatzdatei, insbesondere der Straßenklassse und der Straßennummer, kann noch eine Plausibilitätsprüfung erfolgen. Der Ort kann aufgrund der Ortskoordinatendaten oder aufgrund weiterer in der Referenzdatei zu diesen Ortskoordinatendaten abgespeicherter Daten weiterverarbeitet und/oder ausgegeben werden. Wenn jedoch die übermittelten Ortskoordinatendaten des Ortes in der Referenzdatei im Endgerät nicht enthalten sind, und eventuell auch, falls die Ortszusatzdaten zu den Ortskoordinatendaten in der Referenzdatei nicht mit den übermittelten Ortzusatzdaten übereinstimmen, ist der Ort, auf welchen sich die Informationen des Informationsanbieters beziehen, feststellbar aufgrund der zusammen mit diesen Informationen und ihren Ortskoordinatendaten übertragenen Ortszusatzdaten, indem diese Ortszusatzdaten in der Referenzdatei des Endgerätes gesucht werden. Die zusätzliche Verwendung von Ortszusatzdaten erhöht damit die Wahrscheinlichkeit der richtigen räumlichen Zuordnung von erhaltenen Informationen zu einem Ort im Endgerät und vermeidet auch Fehler, wenn aufgrund beispielsweise aktualisierter Karten oder Verwendung anderer als früher benutzter Karten die geographischen Koordinaten eines bestimmten Ortes laut der aktualisierten oder anderen Karten beim Informationsanbieter ändern bzw. bei einem anderen Informationsanbieter abweichen, während im Endgerät lediglich Ortskoordinaten zu einer bestimmten Kartenversion vorliegen.If information transmitted to an end device by an information provider is transmitted with transmitted location coordinate data in a reference file in the terminal, the location for the terminal is defined. Due to the Ortszusatzdatei, in particular the street class and the street number, can still be a plausibility check. The location can be further processed and / or output based on the location coordinate data or on the basis of further data stored in the reference file for this location coordinate data. However, if the transmitted location coordinate data of the location in the reference file is not included in the terminal, and possibly also if the location auxiliary data is related to the location coordinate data in the terminal Reference file does not match the transmitted location overhead data, the location to which the information provider's information relates can be determined from the location overhead data transmitted along with this information and its location coordinate data by searching that location overhead data in the terminal's reference file. The additional use of location overhead data thus increases the likelihood of proper spatial allocation of received information to a location in the terminal and also avoids errors when, for example, using updated maps or using other than previously used maps, the geographic coordinates of a particular location according to the updated or other maps at the information provider change or differ from another information provider, while in the terminal only location coordinates for a particular map version are present.
Die räumliche Zuordnung von in einem Endgerät empfangenen Informationen zu dem Ort, auf welchen sie sich beziehen, ist durch die Art der mit Informationen von einem Informationsanbieter an ein Endgerät übermittelten Ortskoordinatendaten und Ortszusatzdaten optimierbar.The spatial assignment of information received in a terminal to the location to which it relates can be optimized by the type of location coordinate data and location auxiliary data transmitted to a terminal by information providers.
Insbesondere umfassen, wie oben ausgeführt, Ortszusatzdaten die Straßenklasse und Straßennummer des Ortes, auf welchen sich die empfangenen Informationen beziehen, und/oder die Namen dieser Orte ; die Ortszusatzdaten weisen ferner zweckmäßig Attribute des Ortes auf, wie die Information, ob eine Kreuzung oder Abzweigung vorliegt, auf welche Fahrbahn sie sich beziehen, Anfang, Ende oder Mitte einer Fahrbahn etc..In particular, as noted above, location information includes the street class and street number of the location to which the received information relates, and / or the names of those locations; the additional location data also expediently have attributes of the location, such as the information as to whether there is an intersection or junction, to which lane they relate, beginning, end or middle of a lane etc.
Die Ortskoordinatendaten identifizieren den Ort, auf welchen sich eine Information bezieht, zweckmäßig durch eine Identifikationsnummer, welche die geographischen Koordinaten des Ortes repräsentiert. Bei einer Rundung der geographischen Koordinaten des Ortes auf 10 bis 500 m, insbesondere 100 m, also Aufnahme nur der hierzu höherwertigen Stellen (= ab 100 m-wertig) der Länge und Breite in den Ortskoordinatendaten (= GeoCode-Ortskoordinatendatei), sind die Ortskoordinatendaten sehr kompakt; die geringerwertigen Stellen der Ortskoordinaten, in welchen aufgrund unterschiedlicher Karten häufig Fehler auftreten und welche die räumliche Zuordnung nicht sehr vereinfachen, werden ignoriert.The location coordinate data identifies the location to which information relates, conveniently by an identification number representing the geographical coordinates of the location. When rounding the geographical coordinates of the place to 10 to 500 m, in particular 100 m, so recording only the higher-ranking places (= from 100 m-valued) of the length and width in the location coordinate data (= GeoCode location coordinate file), are the location coordinate data very compact; the least significant digits of the location coordinates, in which errors often occur due to different maps and which do not greatly simplify the spatial allocation, are ignored.
Die Informationen, Ortskoordinatendaten und Ortszusatzdaten werden zweckmäßig in einem vorgegebenen Format und/oder vorgegebener Reihenfolge, vorzugsweise in beidem, von dem Informationsanbieter an das Endgerät übermittelt, was eine automatisierte Verarbeitung im Endgerät erleichtert.The information, location coordinate data and location additional data are expediently transmitted in a predetermined format and / or predetermined order, preferably in both, from the information provider to the terminal, which facilitates automated processing in the terminal.
Insbesondere wenn mehrere standardisierte Kartendateien gebräuchlich sind, ist eine Identifikation derjenigen digitalen Karte eines Verkehrsnetzes, auf welche sich die Ortskoordinatendaten beziehen, vorteilhaft, weil so aufgrund der diesen Ortskoordinaten zugeordneten digitalen Karte im Endgerät der Ort einfacher identifizierbar ist.In particular, when a plurality of standardized map files are in use, an identification of those digital map of a traffic network to which the location coordinate data relate, advantageous because so due to the location coordinates associated with this digital map in the terminal, the place is easier to identify.
Das Verfahren ist zur Übermittlung und räumlichen Zuordnung von unterschiedlichen Informationen einsetzbar. Insbesondere können Informationen Verkehrsinformationen eines Verkehrsinformationsanbieters für ein in einem Fahrzeug anordenbares Endgerät sein. Neben reinen Verkehrsinformationen, beispielsweise zu Staus, Reisezeiten, Durchschnittsgeschwindigkeiten etc. ist das Verfahren insbesondere auch zur interaktiven Navigation einsetzbar, bei welcher eine eindeutige Identifikation eines Navigationsinformationen betreffenden Ortes, beispielsweise des aktuellen Ortes des Fahrzeuges, von Bedeutung ist.The method can be used for the transmission and spatial assignment of different information. In particular, information may be traffic information of a traffic information provider for a terminal that can be arranged in a vehicle. In addition to pure traffic information, such as traffic jams, travel times, average speeds, etc., the method can also be used in particular for interactive navigation, in which an unambiguous identification of a navigation information relevant place, such as the current location of the vehicle, is of importance.
Die Übertragung der Informationen vom Informationsanbieter an das Endgerät kann in unterschiedlicher Weise erfolgen. Möglich ist insbesondere die Übermittlung der Informationen mit oder ohne Kodierung über Radio, Mobilfunk, Paging etc.The transmission of information from the information provider to the terminal can be done in different ways. In particular, it is possible to transmit the information with or without coding via radio, mobile radio, paging, etc.
Die Informationen werden zweckmäßig an einen Benutzer des Endgerätes ausgegeben. Hierfür können sie weiter aufbereitet werden. So kann aufgrund von Ortskoordinatendatendaten und/oder Ortszusatzdaten, ggf. mit weiteren übermittelten oder der Referenzdatei entnommenen Daten eine Meldung für den Benutzer generiert werden. Falls der Ort des Endgerätes diesem bekannt ist, ist insbesondere eine Filterung der Informationen hinsichtlich z.B. örtlicher Relevanz für den Benutzer möglich, wobei lediglich relevante Daten an den Benutzer des Endgerätes ausgegeben werden. Ferner ist bei Kenntnis der Position des Endgerätes, beispielsweise aus GPS, und/oder aufgrund der Verfolgung der Position des Endgerätes in einer Karte unter Berücksichtigung von Geschwindigkeit und Lenkradstellung etc. eine Verknüpfung des Ortes mit den empfangenen Informationen möglich; beispielsweise kann die Meldung "Stau auf A3 zwischen Anschlußstelle x und y" umgewandelt werden in "Stau vor Ihnen in zwei Kilometer Entfernung mit 30 km Länge".The information is expediently output to a user of the terminal. For this they can be further processed. Thus, due to location coordinate data and / or additional location data, possibly with further data transmitted or taken from the reference file, a message for the user can be generated. In particular, if the location of the terminal is known to it, filtering of the information regarding e.g. local relevance to the user possible, with only relevant data is output to the user of the terminal. Furthermore, with knowledge of the position of the terminal, for example from GPS, and / or due to the tracking of the position of the terminal in a map in consideration of speed and steering wheel position, etc., a link of the location with the received information is possible; for example, the message "congestion on A3 between junction x and y" can be converted into "traffic jam in front of you at two kilometers distance with 30 km length".
Des weiteren ist eine Korrektur der Referenzdatei im Endgerät und/oder beim Informationsanbieter bei Divergenzen von übermittelten Ortskoordinatendaten eines Ortes zu aufgrund der mitübermittelten Ortszusatzdaten in der Referenzdatei festgestellten Ortskoordinatendaten möglich. Hierbei ist insbesondere das Laden einer aktualisierten Referenzdatei vom Informationsanbieter zum Endgerät über Mobilfunk etc. möglich. Ferner ist auch eine Einzelkorrektur des speziellen Ortes möglich; beispielsweise können die vom Informationsanbeiter an das Endgerät übermittelten Ortskoordinatendaten zu einem Ort in der Referenzdatei des Endgerätes als Ortskoordinatendaten des Ortes gespeichert werden, welcher dort durch die Ortszusatzdaten definiert ist, welche den mitübermittelten Ortszusatzdaten entsprechen.Furthermore, a correction of the reference file in the terminal and / or the information provider in case of divergences of transmitted location coordinate data of a location is possible due to the co-transmitted location additional data in the reference file location coordinate data. In particular, it is possible to load an updated reference file from the information provider to the terminal via mobile communications, etc. Furthermore, a single correction of the specific location is possible; For example, the location coordinate data transmitted by the information provider to the terminal may be stored to a location in the terminal's reference file as location coordinate data of the location defined there by the location overhead data corresponding to the associated location overhead data.
Ein erfindungsgemäßes Endgerät weist insbesondere eine Referenzdatei mit zumindest einer Zuordnung von Ortskoordinatendaten zu Ortszusatzdaten auf.In particular, a terminal according to the invention has a reference file with at least one assignment of location coordinate data to location auxiliary data on.

Unter Berücksichtigung der in Figur 1 schematisch dargestellten Referenzdatei des Endgerätes werden in Figur 2 dargestellte, zusammen mit Ortskoordinatendaten und Ortszusatzdaten übermittelte Informationen gemäß dem in Figur 3 abstrakt dargestellten Verfahren räumlich zugeordnet.Taking into account the reference file of the terminal shown schematically in FIG. 1, information shown in FIG. 2, transmitted together with location coordinate data and additional location data, is allocated spatially in accordance with the method illustrated abstractly in FIG.
Eine in Figur 2 beispielhaft dargestellte Verkehrsnachricht umfaßt neben der als "Ereignis" (1) und "30 km Stau" (2) dargestellten Information (1,2) als GeoCode bezeichnete Ortskoordinatendaten 3 und Ortszusatzdaten 4,5.A traffic message illustrated by way of example in FIG. 2 comprises, in addition to the information (1,2) represented as "event" (1) and "30 km congestion" (2),
Eine derartige Nachricht wird von einem Informationsanbieter, wie einer Verkehrsinformationszentrale 6 per Mobilfunk, Paging, Radio etc. 7 an ein Endgerät 8 übermittelt.Such a message is transmitted by an information provider, such as a
Im Endgerät 8 wird die Verkehrsinformation 9 aufgrund einer in Fig. 1 dargestellten Referenzdatei 10 räumlich dem Ort, auf welchen sich die Information 1,2 bezieht, zugeordnet. Hierzu können insbesondere die als GeoCode bezeichneten Ortskoordinatendaten 3 verwendet werden. Diese sind hier unter Rundung und Weglassen niederwertiger Stellen auf etwa 100 m Genauigkeit aus der geographischen Länge 12°34'99" und Breite 56°78'99" des Ortes, auf welchen sich die Information bezieht, gebildet (also z.B. 12345678). Damit wäre auch bei nicht möglicher Zuordnung übermittelter Informationen zu einem Ort wegen Fehlens der zu ihnen übermittelten Ortskoordinaten und der Ortszusatzdaten in der Referenzdatei 10 des Endgerätes 8 aufgrund der im GeoCode (z.B. '12345678', = Ortskoordinatendaten) implizierten geographischen Länge und Breite 12°34'W und 56°78'N) eine zumindest ungefähre räumliche Zuordnung der Information 1,2 zu einem Ort möglich. Im einfachsten Falle sind die Ortskoordinatendaten 3 der Verkehrsnachricht in der Referenzdatei im Endgerät 8 auffindbar. Dann werden noch die Ortszusatzdaten 4,5 der Verkehrsnachricht mit Ortszusatzdaten 4,5 in der Referenzdatei 10 im Endgerät 8 sowie ggf. weitere Attribute (wie "Kreuzung", "Karlsplatz") verglichen. Falls unter den übermittelten Ortskoordinatendaten 3 in der Referenzdatei 10 im Endgerät 8 die Ortszusatzdaten 4,5 und evtl. auch die Attribute 11,12 mit den übermittelten übereinstimmen, ist der Ort, auf welchen sich die Information 1,2 bezieht, eindeutig bestimmt und kann zur Relevanzprüfung der Information 1,2 und/oder Ausgabe mit der Information 1,2 an den Benutzer des Endgerätes 8 und/oder Navigation verwendet werden. Die Relevanzprüfung kann z.B. nur die Informationen herausfiltern, welche für den Benutzer aufgrund seines Ortes, der aufgrund einer Routenbestimmung oder/und GPS etc. bestimmbar ist, von Bedeutung ist. Beispielsweise können nur Informationen der Straße, auf welcher sich der Benutzer mit dem Endgerät 8 fortbewegt und/oder in Fahrtrichtung liegende Straßen und/oder ein bestimmter räumlicher Umkreis berücksichtigt werden.In the
Wenn jedoch die Ortszusatzdaten 4,5 unter dem Eintrag in der Referenzdatei 10 zu den übermittelten Ortskoordinatendaten 3 nicht mit den mit diesen Ortskoordinatendaten 3 übermittelten Ortszusatzdaten 4,5 übereinstimmen, wird in der Referenzdatei 10 ein Eintrag mit diesen Ortszusatzdaten 4,5 gesucht und dessen Ort als Ort, auf welchen sich die Information 1,2 bezieht, definiert. Gegebenenfalls können stattdessen oder zusätzlich auch Attribute, wie Namen etc., des Ortes zur Überprüfung verwendet werden. Die Attribute können ferner verwendet werden, um eine an einen Benutzer des Endgerätes 8 auszugebende Nachricht zu ergänzen, beispielsweise durch Hinzufügen eines in der Referenzdatei im Endgeräte gespeicherten Namens ("Abfahrt Pasing") etc. eines Ortes zu diesen Ort betreffenden Informationen.However, if the location
Ein Ablauf der Prüfung ist in Figur 3 dargestellt. Eine von einem Informationsanbieter an ein Endgerät gesandte Verkehrsnachricht 9 mit Ortskoordinatendaten 3 und Ortszusatzdaten 4,5 sowie Informationen 1,2 wird im Endgerät 8 weiterbearbeitet. Hierzu werden die Ortskoordinatendaten 3 der übermittelten Verkehrsnachricht 9 im Endgerät 8 in einer Referenzdatei 10 gesucht (12). Falls sich hier ein Eintrag findet (13), wird dieser durch Vergleich der Ortszusatzdaten 4,5 in der erhaltenen Verkehrsnachricht 9 und in der Referenzdatei 10 im Endgerät 8 geprüft auf Konsistenz und Plausibilität (14). Falls die Ortszusatzdaten 4,5 übereinstimmen, werden die Ortskoordinatendaten 3 als konsolidierte Georeferenz 15 definiert und als Ort 16, auf welchen sich die Information 1,2 bezieht, betrachtet. Falls sich jedoch zu den Ortskoodinatendaten 3 der Verkehrsnachricht 9 kein Eintrag ergibt (17), wird der Ort aufgrund der Ortszusatzdaten 4,5 bestimmt. Dies können insbesondere die Straßenklasse 4 (z.B. "Autobahn" oder "A") und die Straßennummer 5 (z.B. "8") sein. Die Straßenklasse ("A) und die Straßennummer können auch gemeinsam in einem Feld (als "A8") übermittelt werden. Nach dieser Konsistenzprüfung oder Ergänzung 18 wird der so erhaltene Ort als konsolidierte Georeferenz betrachtet (15). Aufgrund dieses Ortes können im Endgerät gespeicherte Attribute, wie der Name ("Stachus" oder "Karlsplatz" oder "Abfahrt Pasing"), zur erhaltenen Information 1,2 bestimmt werden und mit dieser an einen Benutzer (als Beschreibung 19) ausgegeben werden. Ferner kann eine aufgrund des Ortes etc. als relevant betrachtete Information 1,2 mit oder ohne Attribute an einen Benutzer des Endgerätes 8 ausgegeben 20 werden.A sequence of the test is shown in FIG. A
Wenn Ortskoordinatendaten 3 und Ortszusatzdaten 4,5 und/oder evtl. auch Attribute 11 in der Verkehrsnachricht 9 und in der Referenzdatei 10 nicht zusammenpassen, kann z.B. dieser Fehler in der Referenzdatei 10 des Endgerätes 9 automatisch korrigiert werden oder eine neue Referenzdatei 10, beispielsweise über Mobilfunk oder anders, vom Informationsanbieter ins Endgerät geladen werden.If location coordinate
Obige Ausführungen dienen nur als Beispiel. Erfindungsgemäß ist auch eine andere Belegung der Felder der Ortszusatzdaten und/oder Ortskoordinatendaten möglich. Beispielsweise kann alternativ oder zusätzlich zu einem Feld (oder mehreren - hier 4, 5) für ein Straße etc. ein Feld für eine Stadt ("München") vorgesehen sein.The above explanations are only an example. According to the invention, another assignment of the fields of the location additional data and / or location coordinate data is also possible. For example, alternatively or in addition to a field (or more - here 4, 5) for a road, etc., a field for a city ("Munich") may be provided.
Neben der reinen Information, insbesondere Verkehrsinformation, ist das erfindungsgemäße Verfahren auch insbesondere zur Navigation geeignet, da hierfür eine möglichst exakte und möglichst fehlerfreie Ortsbestimmung von großer Bedeutung ist.In addition to the pure information, in particular traffic information, the method according to the invention is also particularly suitable for navigation, since this is as accurate and error-free as possible localization is of great importance.
Im Endgerät 8, welches hier nicht im Detail dargestellt ist, ist das Verfahren in einem Programm implementiert, welches im Endgerät abgespeichert ist. Ferner kann, insbesondere für Navigationsverfahren, eine Kartendatei im Verfahren verwendet und im Endgerät gespeichert sein. Eine Referenzdatei kann im Endgerät abgespeichert sein; eine Referenzdatei kann auch auf einem austauschbaren Speichermedium, wie einer Chipkarte oder dergleichen, gespeichert sein, wobei Daten vom Speicher durch eine Leseeinrichtung im Endgerät eingelesen werden können. Zur Abarbeitung des Programms im Endgerät ist dort ein Prozessor vorgesehen. Die Informationen des Informationsanbieters gehen im Endgerät in einer Empfangseinrichtung für Radio und/oder Mobilfunk und/oder Pager etc. ein. Die Ausgabe von evtl. überarbeiteten oder ergänzten Informationen 1,2 usw. an einen Benutzer des Endgerätes erfolgt über eine beispielsweise akustische oder optische Ausgabeeinrichtung. Ferner kann ein Rückkanal, insbesondere der Uplink eines Mobilfunkkanals, für eine Fehlerkorrektur oder das Herunterladen einer aktuellen Referenzdatei 10 in das Endgerät vorgesehen sein. Das Endgerät ist insbesondere zum Einbau in ein Fahrzeug geeignet. Zur Positionsbestimmung kann es beispielsweise einen GPS-Empfänger und/oder eine Positionsbestimmung durch eine interne Karte, die Lenkradstellung und Kilometer- und/oder Geschwindigkeitszähler etc. umfassen.In the
