  • Patent number: 8320936
    Abstract: A method in a mobile communication system for determining a distance between a first mobile terminal and a second mobile terminal. Based on a trigger distance between the first and the second mobile terminal, a triggered location server defines an area surrounding the first mobile terminal and optionally defines an area surrounding the second mobile terminal. The trigger distance may be provided by an application e.g. for providing a location based service. If the first mobile terminal determines that it has moved outside of its area, it sends a trigger to the triggered location server. If the trigger distance between the first and the second mobile terminal is reached, the triggered location server may report this to the application as an event.

  • Publication number: 20110117922
    Abstract: A method in a mobile communication system for determining a distance between a first mobile terminal (101) and a second mobile terminal (102). Based on a trigger distance (203) between the first and the second mobile terminal (101,102), a triggered location server (104) defines an area 201 surrounding the first mobile terminal (101) and optionally defines an area 202 surrounding the second mobile terminal (102). The trigger distance (203) may be provided by an application e.g. for providing a location based service. If the first mobile terminal (101) determines that it has moved outside of its area, it sends a trigger to the triggered location server (104). If the trigger distance (203) between the first and the second mobile terminal (101,102) is reached, the triggered location server (104) may report this to the application as an event.
