Abstract:
An object of the present invention is to provide a mobile communication system which ensures that hand-over to a small base station, for a specific user provided with a service by the small base station, will always be performed even when the small base station is being used by a general user who does not receive the service. The mobile communication system comprises: a base station; a plurality of small base stations provided in an area covered by the base station as a countermeasure against dead zones of the base station; a terminal for receiving a specific service provided by the plurality of small base stations; and an RNC which has an identification number, registered therein, of the terminal for receiving a service provided by each of the plurality of small base stations, and which, when the identification number from the terminal is received, checks whether or not a free channel is available in the small base station registered corresponding to the identification number, and, if there is no free channel available in the small base station registered corresponding to the identification number, requests that a terminal not registered in the small base station be handed over to another base station and then performs hand-over to the small base station having the identification number of the terminal registered therein.
