MOBILE COMMUNICATIONS NETWORK AND WIRELESS BASE STATION

摘要

A mobile terminal selects a radio base station that is the access point for the mobile terminal in accordance with received-radiowave characteristic values for respective radio base stations. The multiple radio base stations include a macrobase station and multiple picobase stations. Each picobase station includes a load measurement unit adapted for measuring or calculating the communication load index of the picobase station itself; an adjustment-value setting unit adapted for setting an adjustment value that is used by the mobile terminal to change the received-radiowave characteristic value of the picobase station itself, depending on the communication load index; and an adjustment-value signaling unit adapted for signaling the adjustment value set by the adjustment-value setting unit to the mobile terminal.
