Abstract:
1. A method in a base station comprised in a wireless communication system, the base station comprising processing circuitry for automatically adjusting the size of a cell served by the base station, the method comprising: estimating, by the processing circuitry, a parameter value related to the number of unsuccessful connection attempts made by one or more user equipments with respect to the base station during a measurement period and/or related to the number of connections between the base station and one or more user equipments that are dropped during the measurement period; comparing, by the processing circuitry, the estimated parameter value with a threshold value; and adjusting, by the processing circuitry, the size of the cell based on the comparison result, wherein adjusting the size of the cell comprises decreasing the size of the cell if the estimated parameter value exceeds the threshold value, and wherein the size of the cell is decreased by increasing a cell edge threshold value related to the extension of the cell border, which cell edge threshold value serves as a threshold value for a user equipment attempting to be served by the base station in the cell, such that the user equipment is served by the base station if a received signal strength as perceived at the user equipment for the cell exceeds the cell edge threshold value.
