Claim Text:
1. A mobile communication method applied to a mobile communication system comprising a general base station that manages a general cell and a specific base station that manages a specific cell, the method comprising: a step A of notifying, by the general base station, the specific base station of scheduling information indicating an uplink radio resource to be assigned to general mobile terminals that are mobile terminals in a connected state in the general cell, at a time interval of a predetermined time; and a step B of notifying, by the specific base station, the general base station of general mobile terminal interference information indicating interference that the specific cell receives according to the uplink signals transmitted from the general mobile terminals at the time interval of the predetermined time after the step A; wherein the general mobile terminal interference information indicates an interference received by the specific cell according to an uplink signals transmitted from the general mobile terminals at the time interval of the predetermined time, the specific cell has a coverage area smaller than a coverage area of the general cell, the general mobile terminal interference information includes an identifier of the general mobile terminal giving interference to the specific cell at the time interval of the predetermined time, the time interval of the predetermined time includes a plurality of unit times at which an uplink radio resource is to be assigned to the general mobile terminals, a time interval of a first predetermined time is set as the time interval of the predetermined time and a time interval of a second predetermined time is set after the time interval of the predetermined time, and the method comprises: a step E of assigning, by the general base station to the general mobile terminal identified according to the identifier included in the general mobile terminal interference information corresponding to the time interval of the first predetermined time, a same uplink radio resource at the plurality of unit times included in the time interval of the second predetermined time; and a step F of instructing, by the general base station, the general mobile terminal identified according to the identifier included in the general mobile terminal interference information corresponding to the time interval of the second predetermined time to perform handover to a frequency that is different from a frequency used in the specific cell.
