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.Field of SearchHandoffMobile assisted or initiated Serving site initiated Handoff initiated by another source (e.g., target, user initiated, mobile switching center (MSC), or mobile telephone switching office (MTSO), etc.) Base station detail Channel allocation Having storage detail Channel seizing To or from mobile station Multiple base stations Base station selection Optimum frequency selection Including private cordless extension system Multi-users Channel selection or allocation Including public cordless extension system | |
