Abstract

The invention provides a method for the determination of a velocity of a user equipment by means of location services, wherein the velocity of a user equipment is calculated by a radio access network node.

Claims

1-4. -4. (Cancelled).

5. A method for the determination of velocity information of a user equipment by means of a location service, wherein said calculation is performed by a radio access network, said method comprising the steps of:

determining a first location of the user equipment;

determining a second location of the user equipment;

determining the time difference between the determination of the first and the determination of the second location; and

determining the velocity of the user equipment based on the first location, the second location and the time difference.

8. A radio access network node adapted to determine a velocity of a user equipment, said network comprising:

means for determining a first position of a user equipment;

means for determining a second position of the user equipment;

means for determining the time difference between the determination of the first and the determination of the second location; and

means for determining the velocity of the user equipment based on the first location, the second location and the time difference.
