ABSTRACT:
In a mobile communication apparatus, power consumption at the time of waiting can be reduced, and hand-off can be easily performed to other systems. The mobile communication apparatus is provided with a memory part (32) which memorizes a selection signal of the first fixed communication apparatus for selecting the first fixed communication apparatuses, the signal being obtained by receiving a signal transmitted from the first fixed communication apparatuses when a hand-off is performed between the first and second fixed communication apparatuses; a comparing part (33) for comparing a memorized selection signal of said first fixed communication apparatuses with a newly received selection signal of the first fixed communication apparatus; and a hand-off process part (31) for performing hand-off to a second fixed communication apparatus from said first fixed communication apparatus in accordance with the comparison result. Thus, hand-off can be easily performed to second fixed communication apparatus, and power consumption during the waiting time can be reduced.
