A cellular telephone system comprises a plurality of base stations which cover a plurality of cells. The system also includes a plurality of portable telephones communicable with the base station over radio frequency channels. A base station covering a given cell transmits an IM control signal indicating that there exists IM interference in the given cell. In response to the IM control signal, each of the portable telephones reduces its receiver sensitivity, so that the IM interference can be alleviated. |
