Abstract
To save energy and to increase the standby time and talk time of a mobile telephone, the activity of the mobile telephone is segmented, even during standby periods, and activation is allowed to occur only if the reception quality of signaling surrounding the standby condition is sufficient. When the mobile telephone is on standby, given the redundancy of the activation signaling, only some of the signals are listened to in order to decide whether it is necessary to listen to the others and to activate the mobile telephone. When the mobile telephone is communicating and the other party is silent, the energy consumed in receiving and above all in decoding the received signals is reduced by eliminating demodulated signals of too poor quality.
