ABSTRACT:
A method for saving battery power in a wireless telephone which receives mode information from a base station in which information on a first mode where only a voice channel is searched, information on a second mode where a voice channel and a data channel are alternately searched while changing a search period of the data channel, and information on a third mode where a voice channel and a data channel are alternately searched at stated periods are registered. The method comprises searching mode information transmitted from the base station; searching a voice channel upon receiving first mode information from the base station; alternately searching a voice channel and a data channel while changing a search period of the data channel, upon receiving second mode information from the base station; and alternately searching the voice channel and the data channel at stated periods, upon receiving third mode information from the base station.
