ABSTRACT:
A method for controlling a mobile communication device to enter a power-saving mode and to recover timing after the mobile communication device leaves the power-saving mode. The mobile communication device communicates with a base station through a time division multiple access (TDMA) system so that wireless signals are transmitted via frames. The method includes executing a sleep mode managing/timing recovering program for interrupting other control procedures, utilizing the sleep mode managing/timing recovering program to calculate a predetermined sleep period, controlling the mobile communication device to enter the sleep mode, executing the sleep mode managing/timing recovering program for stopping a clock signal from driving a micro-controller unit during an actual sleep period, controlling the mobile communication device to terminate the sleep mode, and executing the sleep mode managing/timing recovering program for synchronizing timing of the mobile communication device with timing of the base station according to the actual sleep period.
