Patent ID: 8509771

Claim:
A base station of a mobile communication system comprising: means for transmitting a pilot beacon to allow a mobile terminal to detect the base station; means for registering information on a mobile terminal to use the base station or information on a user corresponding to a mobile terminal to use the base station; means for controlling the transmission unit to stop transmission of the pilot beacon if a mobile terminal corresponding to the information registered with the registration unit performs handoff to the base station; means for receiving a radio wave transmitted to another base station from a mobile terminal location-registered with the another base station of the mobile communication system; and means for obtaining information on a mobile terminal location-registered with the another base station or information on a user corresponding to the mobile terminal from a mobile communication network to which the another base station is connected, wherein the means for controlling controls the means for obtaining information to obtain information on a mobile terminal having an intensity of a radio wave received by the means for receiving a radio wave equal to or higher than a threshold or information on the user corresponding to the mobile terminal based on an identifier included in the radio wave having the intensity equal to or higher than the threshold while transmission of the pilot beacon is stopped, and if the mobile terminal corresponding to the obtained information is registered with the means for registering information, the means for controlling controls the means for transmitting a pilot beacon to resume transmission of the pilot beacon, and the means for controlling controls the means for receiving to stop reception of the radio wave if all mobile terminals registered with the means for registering information are location-registered with the base station based on information on the mobile terminals location-registered with the base station or information on users corresponding to the mobile terminals, and also based on information on the mobile terminals registered with the means for registering information or information on users corresponding to the mobile terminals.
