Patent ID: 8412219

Claim:
A base station comprising: a scheduling unit configured to allocate a radio resource to be used for reception of uplink data; and a call reception control unit configured to control reception of a call, wherein: the scheduling unit includes a reporting unit configured to report a total resource allocation amount of the radio resource to the call reception control unit at predetermined intervals, the radio resource being allocated by the scheduling unit; the call reception control unit includes a management unit configured to manage a total resource usage amount of the radio resource used for reception of uplink data by updating the total resource usage amount of the radio resource used for reception of uplink data on the basis of the total resource allocation amount reported by the scheduling unit, and a determination unit configured to determine whether or not reception of a new call is permissible by adding an initial radio resource to be allocated to the new call to the total resource usage amount managed by the management unit; in response to release of an existing call for which the scheduling unit does not perform radio resource allocation at each transmission time interval, the management unit updates the total resource usage amount by subtracting the radio resource allocated to the existing call for which the scheduling unit does not perform the radio resource allocation at each transmission time interval; and in response to release of an existing call for which the scheduling unit performs radio resource allocation at each transmission time interval, the management unit manages the total resource usage amount without subtracting the radio resource allocated to the existing call for which the scheduling unit performs the radio resource allocation at each transmission time interval.
