Abstract:
1. A method comprising: reducing an original coverage area of a first cell of a cellular communication network by decreasing a transmission power of a pilot channel transmitted by a base station corresponding to the first cell when uplink interference in the first cell area increases above a threshold uplink interference value that is determined independent of the transmission power of the pilot channel, a mobile terminal being positioned at an edge of the first cell area, the mobile terminal having previously selected the first cell to be connected to; and at the mobile terminal, reselecting to a neighboring second cell of the cellular communication network in response to the reduction in coverage area of the first cell; and maintaining a minimum coverage area of the first cell by transmitting the pilot channel at a minimum transmission power when the uplink interference is above a further threshold value that is larger than the threshold uplink interference value.
