Claim Text:
1. A method in a radio base station in a communication network for determining where in a cell a user equipment, UE, being served by the radio base station is located, wherein the radio base station has a coverage area defining the cell, the method comprising: receiving at least a first and subsequently a second Reference Signal Received Power, RSRP, value from the UE, comparing the received first and second RSRP values, selecting a first threshold value based on the comparison indicating increasing RSRP values corresponding to the UE moving towards a cell-centre area, or selecting a second threshold value based on the comparison indicating decreasing RSRP values corresponding to the UE moving towards a cell-edge area, determining a factor, f, which is the ratio between a received RSRP value of the radio base station and a sum of RSRP values of neighbouring radio base stations for the UE, and comparing the factor f with said first and second threshold values in order to determine the location of the UE in the cell.
