Abstract
The process for controlling the power supply (16) of a telephone (1) of a cellular radiotelephone network (2), of which the transmission power (13) is controlled (14) by the network (2) according to a power class indicated by the telephone (1), consists of determining the charge level of the power supply (16), deducing the maximum transmission power able to be reached, according to the charge level, comparing the maximum transmission power and the transmission power controlled (14) by the network (2), and downgrading the mobile telephone (1) if the former is lower than the latter (14).

Process for controlling the power supply (16) of a mobile telephone (1) of a cellular radiotelephone network (2), of which the transmission power (13) is controlled (14) by the network (2) according to a power class indicated by the telephone (1), the process being characterised in that
- the charge level of the power supply (16) is determined,
- the maximum transmission power able to be reached is deduced from the charge level,
- the maximum transmission power and the transmission power controlled (14) by the network (2) are compared, and
- the mobile telephone (1) is downgraded if the former is lower than the latter (14).
Processing according to 3, wherein the maximum transmission power is estimated according to the current output by the power supply (16).
