Battery saving method in mobile voice communications

摘要

The system enables the battery power to be conserved when there is no received speech signal. The circuit for reception of speech signals in a mobile telephone (1) operates with speech signals which are distributed in time windows situated in successive frames. The process includes the reception of the first speech signals corresponding to a first time window. This is followed by measurement of quality information relating to the received speech signals and comparing this with a first threshold. The mobile telephone is then configured to receive, or not receive, the second speech signal corresponding to a second time window as a function of this comparison.
