1. A method of cutting off a transmission signal of a main transmitter of a mobile telephone relayed by a cell of a base station, the method comprising:
- cutting off the transmission signal by the main transmitter of the mobile telephone if the power of the transmission signal emitted by the main transmitter of the mobile telephone is greater than the power of each transmission signal of other transmitters relayed by the same cell of the base station, andif the power of the transmission signal of the main transmitter of the mobile telephone does not decrease after several identical successive transmitted-power regulating commands (TPC) emitted by the base station.

Abstract
Method of cutting off a transmission signal of a main transmitter relayed by a cell of a base station and associated system. According to this method, the transmission signal is cut off:—if the power of the transmission signal emitted by the main transmitter is greater than the power of each transmission signal of other transmitters relayed by the same cell of the base station, and—if the power of the transmission signal of the main transmitter does not decrease after several identical successive transmitted-power regulating commands (TPC) emitted by the base station.

6. A system for cutting off the transmission signal of a main transmitter of a mobile telephone relayed by a cell of a base station, the system comprising:
- the main transmitter of the mobile telephone comprising a receiver to receive transmitted-power regulating commands (TPC) emitted by a base station and a transmitter to transmit the signal emitted by the main transmitter, comprising a first integrator to compute a sum of the power variation commands of the transmitted-power regulating commands (TPC) emitted by the base station, a second integrator to compute a sum of the corresponding variations of effective power that are emitted by the main transmitter, a comparator to compare the sum of the power variation commands with the sum of the variations of corresponding effective power, and a generator to generate a cut-off signal for the main transmitter of the mobile telephone, the generator being of the main transmitter.
