Abstract

A mobile terminal judges whether a handover is required (S1). If yes, the mobile terminal measures reception intensities of the mobile terminal for signals transmitted by a plurality of radio base stations (S2). A management device records in adjacent area information, that a communication area of a radio base station corresponding to a reception intensity exceeding the lower limit among the reception intensities obtained by the measurement is adjacent to a communication area of the radio base station connected to the mobile terminal (S5). The radio base station selects a candidate of the radio base station for a handover of the mobile terminal from the adjacent area information and sets a priority based on the measured reception intensity for the candidate (S7). The mobile terminal executes a handover according to the priority for the candidate of the handover (S10).
