Definitions

  • the present invention relates to a method and a service for providing dynamic tracking of a group of mobile terminals.
  • Location based services is also used for assistance, such as identifying closest gas station or hospital based on the location of the mobile terminal.
  • the concept of location-based services is also being used in the context of tracking movement: of specific individuals, for example prisoners, and of goods and vehicles.
  • Prior art method of tracking using location based services relies on a static geographical area in which the mobile terminal is to be tracked, i.e. a city or a province. However, the prior art does not deal efficiently with dynamic areas for tracking of a group of mobile terminals.
  • the present invention is a method for performing dynamic tracking of a group of mobile terminals.
  • the method includes steps of defining a group of mobile terminals, and identifying one of the mobile terminals as a reference point. A maximum distance to be respected between the reference point and each of the mobile terminals of the group is defined. An actual distance between each of the mobile terminals of the group and the reference point is measured. A warning signal is issued when one of the mobile terminals' actual distance exceeds the defined maximum distance.
  • the present invention is a service node for performing dynamic group tracking of a group of mobile terminals.
  • the service nodes consists of a group definition means for identifying a plurality of mobile terminals belonging to the group.
  • the group definition means includes a reference indicator for identifying one of the plurality of mobile terminals as a reference point.
  • the service node also includes a service definition means for defining a maximum distance to be respected by each mobile terminal of the group with respect to the reference point.
  • An input means receives location information for each of the mobile terminals belonging to the group.
  • a distance measuring means calculates an actual distance between each of the mobile terminals belonging to the group and the reference point, based on the received location information by the input means. Then, a warning means verifies that the actual distance calculated by the distance measuring means is shorter than the maximum distance and generates a warning signal if the actual distance of one of the mobile terminals of the group is greater than the maximum distance.

For example, triangulation may be used to determine each mobile terminal's location. Then, the difference between the locations is calculated to obtain the actual distance. It should be understood by those skilled in the art that any method for determining the actual distance between one of the mobile terminal of the group and the reference point may be used without departing from the scope of protection of the present invention.
  • step 408 verification is made to determine whether the actual distance of any of the mobile terminals of the group exceeds the specified maximum distance. If the actual distance of one of the mobile terminal is greater than the specified maximum distance, a warning signal is issued (step 410).
