Abstract

The invention relates to the provision of deferred location reporting wherein the reporting is triggered by a trigger location change event. Trigger location change events are either related to a user of a cellular telecommunication network entering, leaving or changing an area, or to an area, which is entered or left by a user.

Claims

1. Method for deferred provision of location information of a user of a cellular telecommunication network to a client external to the network, wherein the method comprises the steps of:

defining (11, 21) or receiving a definition of at least one trigger location change event for a user,

receiving (12, 22) from the client (C1) a request for a deferred provision of deferred location information for a user,

monitoring (13, 23) said trigger location change event for said user,

detecting (14, 24) the occurrence of the trigger event,

determining (15, 25) the location of the user,

transforming location information of a user related to a structure of the cellular telecommunication network into location information related to geographical coordinates, and

providing (16, 26) the location of the user to the client.

2. Method according to claim 1, wherein a trigger location change event is a change, an entering, or a leaving of one of an area served by a mobile services switching centre, a serving General Packet Radio Service support node, a cell, a location area, a routing area, or a service area.

3. Method according to any of the preceding claims, wherein the determining of the location of the user comprises the execution of a positioning method.

4. Method according to any of the preceding claims, wherein the user dedicates the accuracy of location information provided to the client.

5. Method according to any of the preceding claims, wherein equipment of the user performs the monitoring and detecting of a trigger location change event and initiates the provision of the location to the client.

6. Method according to any of the preceding claims, wherein a node of the cellular telecommunication network performs the monitoring and detecting of a trigger location change event and initiates the provision of location information to the client.

7. Method according to claim 6, wherein a node performing home location register functions stores an indicator that a trigger location change event is defined for the subscriber.

8. Method according to claim 6 or 7, with the additional step of verifying that the user granted a permission to provide the client with location information.

9. Method according to any of the preceding claims, wherein the trigger location event is defined as an entering or leaving of a particular predefined area.

10. Method according to claim 9, wherein information about the velocity of a user when entering or leaving the particular predefined area is provided to the client.

11. User equipment for communicating in a cellular telecommunication network characterised by means for monitoring whether a change, an entering, or a leaving of one of an area served by a mobile services switching centre, a serving General Packet Radio Service support node, a cell, a location area, a routing area, or a service area occurred, and means for initiating a determining of the location of the user equipment.
