A method of operating wireless communications network and base station for use in wireless communication network

A wireless communications network comprising a first plurality of base stations serving a second plurality of subscriber stations and at least one Radio Network Controller controlling said plurality of base stations, wherein a base station is adapted to detect a malfunction affecting provision of services by the base station, determine cell affected by said malfunction;

• the base station is also adapted to reduce power of signal transmitted in the affected cell if said base station continues to transmit signal in said affected cell and the Radio Network Controller is adapted to request adjustment of power of signal transmitted by base stations in cells adjacent to said affected cell to provide network coverage for the affected cell.

A base station for use in a wireless communications network adapted to detect a malfunction affecting services provided by said base station, determine cell affected by said malfunction and, if the base station continues to transmit signal in the affected cell, to reduce power of signal transmitted by said base station in the cell affected by the malfunction.
