Abstract: A mobile communication method is applied to a mobile communication system including a general base station and a specific base station. A distance between an edge closest to the general base station among edges of a coverage area of the specific cell and the general base station is a distance LMIN. A distance between an edge most distant from the general base station among the edges of the coverage area of the specific cell and the general base station is a distance LMAX. The mobile communication method comprises: a step A of instructing, by the general base station, a general mobile terminal, located in a belt-like annular area indicating a range from the distance LMIN to the distance LMAX in a connected state in the general cell, to perform handover to a frequency different from a frequency used in the specific cell.

Abstract: A communication control method in a mobile communication system having a first base station and a second base station having a smaller coverage area than the first base station, comprises: a step A of transmitting information indicating interference in uplink detected by the second base station, from the second base station to the first base station; a step B of performing processing by the first base station and/or the second base station to change a radio environment around the boundary of a coverage area of the second base station; and a step C of identifying an interfering user terminal in the uplink by the first base station, from first user terminals being connected with the first base station, based on radio environment information reported by the first user terminals.

Abstract: A communication control method in a mobile communication system, comprises: a step A of transmitting, from a first base station, a first synchronization signal at a first frequency band in the center of a particular carrier, the first synchronization signal being for use to establish synchronization; and a step B of transmitting, from the first base station, a second synchronization signal in a second frequency band different from the first frequency band within the particular carrier, the second synchronization signal being for use to establish synchronization.
