Patent ID: 6850761

Claim:
A method for determining the position of a mobile station located in a coverage area of a base station in a radio system and for using location information, in which method the base station comprises equipment for receiving signals from the same mobile station simultaneously by at least two antenna beams directed in different directions, the method comprising: measuring signal levels of signals received from a same mobile station by different antenna beams of said base station, comparing the signal levels of the signals received from the same mobile station by the different antenna beams, determining a direction to the mobile station in relation to the bas station on the basis of a relations between the signal levels measured for the different antenna beams, and calculating a distance from the mobile station to the base station on the basis of a timing advance, given to the mobile station by the base station and propagation speed of the radio signals, wherein said distance and said direction is used for making a decision whether or not said mobile station should be transferred to another base station by a handover.
