Abstract

When a handover standby threshold falls below a received power of perch channel from a base station 150-1 of a communication partner, a mobile station 110 sends a handover standby operation request to a base station control apparatus 130, and notifies of history of movement of itself and receives powers of perch channels from base stations 150-2–150-4 surrounding the communication partner (mobile station information). The base station control apparatus 130 compares the mobile station information with history of mobile station information so that a handover destination candidate base station is selected and sent to the mobile station 110. The mobile station 110 switches the communication partner to the handover destination candidate base station when received power of the perch channel from the base station 150-1 falls below a handover threshold.
