Patent ID: 8457068

Claim:
A method for adjusting transmission power of at least one of signals transmitted by a first base station and signals transmitted to the first base station, a cell of the first base station being at least partly comprised in a cell of a second base station, wherein the method is executed by the first base station and comprises: obtaining information related to a coverage area of the second base station and at least one of information related to a path between the second base station and at least one mobile terminal for which a handover has been previously conducted between the first and second base stations and information related to a path between the second base station and a mobile terminal for which a handover has to be conducted between the first and second base stations; computing a metric from the obtained information; and adjusting, according to the computed metric, the transmission power of the at least one of the signals transmitted by the first base station to at least one mobile terminal served by the first base station and the signals transmitted to the first base station by at least one mobile terminal served by the first base station, wherein the obtaining includes determining in the first base station the information related to the coverage area of the second base station, receiving in the first base station from the second base station the at least one of the information related to the path between the second base station and the at least one mobile terminal for which the handover has been previously conducted between the first and second base stations and the information related to the path between the second base station and the mobile terminal for which the handover has to be conducted between the first and second base stations, and dividing the received at least one of the information related to the path between the second base station and the at least one mobile terminal for which the handover has been previously conducted between the first and second base stations and the information related to the path between the second base station and the mobile terminal for which the handover has to be conducted between the first and second base stations by information determined in the first base station and related to the coverage area of the second base station.
