  • the present invention employs 'representative' locations (e.g., a proxy location, a pseudo location, an abstract location, a symbolic location, etc.), and allows the user to set different user preferences for different locations to provide the user with different terminal operations according to his physical location.
  • 'representative' locations e.g., a proxy location, a pseudo location, an abstract location, a symbolic location, etc.
  • the use of 'representative' locations and different user preferences for different locations can provide the user with different terminal operations depending upon where the user is physical located.
  • the present invention provides a location information system that reflects (or considers) user preference information (e.g., user profile settings), provides an interface between each entity of such system, and provides a scheme for activating the user preference information that is set (or designated or established) for a particular region (e.g., physical location) when the user physically moves into (or enters) the corresponding location (or region) that has been previously set.
  • user preference information e.g., user profile settings
  • a location information system reflecting user preference information refers to being able to set different terminal operations and functions for a certain region (physical location) designated by the user.
  • the user of a terminal may set (designate) his ring tone to vibrate mode when at work and to bell sound mode when at home, and also set (designate) his terminal such that international calls cannot be made when at home or such that data service cannot be received.
  • the terminal can detect such settings as the user moves about with his terminal such that the terminal is automatically put in vibrat e mode when the user enters his workplace or put in ring mode when the user leaves his workplace.
  • the user preference information (e.g., a user profile) can be stored in a network entity called a user preference repository (e.g., Privacy Check Entity: PCE), and when a request for location tracking of a user is received (i.e., a request to track the current location of the user's terminal), the user's actual physical location value (e.g., x, y, z coordinates, GPS coordinates, etc.) is not reported, but a value that represents the location (or region or area) pre-designated by the user (namely, a representative location, a proxy location, a pseudo location, an abstract location, a symbolic location, a conceptual location, a theoretical location, etc.) that reflects (or considers) the user preference information is employed for reporting.
  • a user preference repository e.g., Privacy Check Entity: PCE
  • PCE Privacy Check Entity
  • the representative location does not indicate the user's actual physical location, but may preferably indicates a larger region or wider area in which the user is physically located.
  • One advantage of employing the concept of 'representative locations' is that the various necessary information and corresponding relationships between the user's actual location (which may continuously change due to the user's mobility) and the user preferences (profile settings allowing the user's terminal to operate in a certain manner) designated for certain physical locations are more efficiently handled and managed.
  • This reporting of the 'representative location' refers to checking the user profile (e.g., the PCE) having user preferences stored therein, comparing the user's actual physical location value with a pre-designated user preference upon receiving a user location tracking request, and reporting a representative location that represents (or signifies or denotes) the user's actual location.
  • the representative location indicates one of the locations within one or more ranges of a 'preference zone' that had been designated by the user. For example, the user may designate one of his preference zones to be called 'home', which may indicate the city in which he resides in.
  • This 'home' zone may have one or more ranges (e.g., smaller regions, boundaries, territories, etc.) designated therein, such as neighborhood names, and each range would have its own representative location that would be used to report the neighborhood name that the user is located in, instead of the user's actual location at a particular street or address within that neighborhood.
  • ranges e.g., smaller regions, boundaries, territories, etc.
  • regions can be set as a representative location, and many representative locations can be set differently for each respective region.
  • the regions that are set as a preference zone and the user preference information of each preference zone may be set or modified only by the authorized user himself.
  • Figure 1 depicts an exemplary structure of the location information system of an embodiment of the present invention.
  • the location information system can be comprised of a storage media 10, a location server 11, a remote server 12 and a user terminal 13.
  • the storage media 10 is a network element that exists at one portion of the wireless network, and an example would include a Privacy Check Entity (PCE) or the like.
  • PCE Privacy Check Entity
  • the storage media 10 stores user preference information (user profiles) related to a terminal operation in a particular region, user preference information (e.g., representative locations) that are set for each range of a user preference zone, and the like.
  • the location server 11 can comprise a subscriber profile function unit, a location calculation function unit that calculates a current location of the terminal (user), and other entities necessary to support the location information service.
  • the subscriber profile function unit can store information regarding whether a service (referred to as a 'user preference service' hereafter) related to a terminal operation in a particular region has been set or not (e.g., user preference service is on or off), and information related to the user preference zone that is set by the user. Because the related art entities that handled the location information service did not perform any functions related to user preference information according to the user's location, it can be said that such new particular entities for handling the functions related to the preference information are necessary.
  • the subscriber profile function unit stores the information related to the preference zone and the information related to whether a preference information service was set or not, and when the user enters a particular location, appropriate procedures are performed to allow activation of the particular terminal operations (e.g., user preferences) that the user had designated. Namely, the subscriber profile function unit reports to the remote server 12 that the user has entered a user preference zone, which was designated by that user, and allows the remote server 12 to activate the preference information pre-designated by the user.
  • the remote server 12 can request and receive the user preference information of the particular region that is stored in the storage media 10.
  • the subscriber profile function unit compares the user's actual physical location value provided from the location calculation function unit with the preference information stored in the storage media 10, and reports the 'representative location' that is set for the user preference information.

  • the remote server 12 may be a physical entity that exists independently, or may be included within one entity that is already part of a conventional wireless network architecture. Thus, for activating the operations of a particular terminal 13 in a few regions designated by the user, interfaces between the location server 11 and the remote server 12, between the storage media 10 and the remote server 12, and between the remote server 12 and the terminal 13 must be separately defined. Also, the storage media 10 and the remote server 12 are indicated as being separate entities, but in another embodiment, the storage media 10 may be included within the remote server 12.
  • the operation of a particular terminal is set according to the user's location, and a field that can transfer the set preference information per user location is added within the protocol interface between the terminal 13 and the storage media 10. Namely, a field for transferring preference information is added to the data transmission format between the terminal 13 and the storage media 10.
  • the storage media 10 can store particular user preference information, and the location server 11 can determine whether the user enters a preference zone previously set by the user and reports this to the remote server 12. Accordingly, the remote server 12 activates the preference information (particular operation) of the terminal 13 designated by the user if the user enters a user preference zone.

As a result of the check, if the user's current location is within a particular registered preference zone, the subscriber profile function unit reports this fact to the remote server 12, but if the user's current location is not within a particular preference zone, then the process returns to step S12.

Abstract

L'invention a pour but de fournir, à des utilisateurs dotés de terminaux sans fil ou mobiles, un mécanisme destiné à rapporter un emplacement représentatif, sur la base d'établissement de profils d'utilisateurs et d'emplacements physiques courants d'utilisateurs. L'emplacement représentatif n'est pas l'emplacement physique actuel de l'utilisateur, mais un emplacement conceptuel utilisé pour signaler l'emplacement physique de l'utilisateur, en vue d'activer diverses fonctions et capacités du terminal utilisateur, conformément à l'endroit où se trouve l'utilisateur. Il devient alors possible, en employant des emplacements représentatifs, de traiter et de gérer plus efficacement diverses informations requises et des relations correspondantes entre l'emplacement réel de l'utilisateur, emplacement qui peut continuellement changer en raison de la mobilité de l'utilisateur, ainsi que les préférences de l'utilisateur contenant des établissements de profils permettant au terminal utilisateur de fonctionner de la manière prévue pour certains emplacements physiques.
