摘要： A mobile station connected to a wireless communication network includes a surrounding environment recording unit configured to record a surrounding environment of the mobile station; a proximity determination unit; and a proximity indication generation unit configured to generate a proximity indication. The proximity determination unit compares a past surrounding environment record that has been recorded by the surrounding environment recording unit with the current surrounding environment record. When the surrounding environment records correspond to each other, or when a degree of similarity between the surrounding environment records exceeds a predetermined degree, the proximity determination unit determines that the mobile station is in proximity to a predetermined home cell base station, and transmits the proximity indication generated by the proximity indication generating unit to a macro cell base station in response to determination that the mobile station is in proximity to the predetermined home cell base station.
