Patent ID: 8417274

Claim:
A base station comprising: a scheduling unit configured to assign a radio resource used for receiving uplink data by transmitting transmission rate control data for controlling transmission rate for uplink data; and a call admission control unit configured to control an admission of a call, wherein the scheduling unit comprises: a first determination unit configured to determine whether or not a transmission frequency of transmission rate control data for decreasing transmission rate for uplink data is equal to or higher than a transmission frequency threshold, a second determination unit configured to determine whether or not a counted number value of rate lowering event occurrences exceeds a counted number threshold, the rate lowering event being an event that decreases transmission rate for uplink data, and a setting unit configured to set admission permission information to information for limiting an admission of a new call in a case where the transmission frequency is equal to or higher than the transmission frequency threshold, and where the counted number value of rate lowering event occurrences exceeds the counted number threshold, and the call admission control unit determines whether or not to permit the admission of a new call based on the admission permission information set by the scheduling unit.
