ABSTRACT:
A method and apparatus for reducing power consumption by controlling listening periods in a wireless telecommunications device having a plurality of power-saving modes are provided. The method includes: setting a first power-saving mode and a second power-saving mode, each of the first and second power-saving modes having a power-saving mode period in which power is saved and data is not transmitted and received, and a standby period in which data is transmitted and received; detecting the standby mode periods from the first and second power-saving modes; adjusting starting periods of the first and second power-saving modes so that the detected standby mode periods of the first and second power-saving modes overlap; and controlling power according to the adjusted first and the second power-saving modes.
