Patent ID: 8411555

Claim:
A method for evaluating a second cell for a potential handover of a terminal that is served by a first cell, wherein the first and the second cells are co-located, and wherein the second cell is operating on a second frequency carrier in a OFDM system and the first cell operating on a first frequency carrier other than the second frequency carrier in the OFDM system or the first cell is operating in another radio access technology system than the OFDM system, the method comprising: receiving measures from the terminal on the quality of the first and the second cell, wherein the quality measure of the first and second cells comprises an intra-cell interference component and the quality measure of the first cell includes an intra-cell interference component if the first cell is included in the OFDM system; detecting the downlink carrier power of the second cell; adjusting the quality measure received from the second cell, by compensating for the intra-cell interference component in the quality measures and compensating for the intra-cell interference component in the quality measure of the first cell if the first cell is included in the OFDM system; evaluating the best cell for serving the terminal by comparing the adjusted quality measure of the second cell with the quality measure of the first cell, as adjusted if the first cell is included in the OFDM system.
