The invention relates to a method of generating a time base in a mobile telephone, which only involves the use of a high-frequency oscillator (304), the commonly-used low-frequency oscillator being eliminated. In this way, the invention reverts to the initial architecture for mobile telephones, in which only a high-frequency oscillator was used to generate a time base. According to the invention, in order to limit the power consumption of a mobile telephone that is not in a communication mode, different operating modes (301; 302; 303) are provided, each operating mode being associated with a specific power supply mode for the time-base-generating system. In this way, the mobile telephone passes from one power supply mode to another depending on the operating conditions thereof. |
