Patent ID: 7079873

Claim:
A method for reducing transmission power consumption of a cell phone, the cell phone comprising: a transceiver module for transmitting signals to a base station and receiving signals transmitted from the base station; and a processor for controlling operation of the cell phone; wherein when the transceiver module receives a receiving time data transmitted from the base station, the processor reads a receiving time interval from the receiving time data; if the processor transmits a connection signal to the base station through the transceiver module after the receiving time interval, the base station transmits another receiving time data to the cell phone; the method comprising: when the transceiver module receives the receiving time data transmitted from the base station, determining a virtual receiving time interval according to the receiving time interval in the receiving time data, the virtual receiving time interval being longer than the receiving time interval; stopping signal transmission to the base station until the virtual receiving time interval is passed; and resuming the connection signal transmission to the base station after the virtual receiving time interval.
