Abstract

The invention relates to a phone unit in which power consumption required to change connection between base stations is reduced. A control section (figure 2) compares the signal strength of a local station with a threshold value and, when it is not lower, continues communication. When the signal strength of the local station is determined to be lower than the threshold, a detecting section (16) detects the signal strengths of other base stations and comparison means (18) selects the one with the highest strength. Moreover, the comparison means compares the signal strength of the selected base station with that of the local station and, when it exceeds that of the local station, switches connection from the local station to the selected station. Consequently, when the phone unit exists in a zone of adequate power, no base station detecting operation is executed and the power associated with the detecting operation is conserved.
