A base station includes a connection processing unit that performs connection processes between user terminals registered in a user terminal registration unit and the base station, and between user terminals other than the user terminals registered in the user terminal registration unit and the base station; a resource amount measurement unit that measures an amount of resources utilized by the base station; and a call disconnection user terminal selecting unit that selects, when the resource amount measurement unit measures that the amount of the resources is greater than or equal to a predetermined threshold value, the user terminal for which a call is to be disconnected, among the user terminals other than the user terminals registered in the user terminal registration unit. The connection processing unit disconnects a connection with the user terminal for which the call is to be disconnected.

A base station includes a call connection acceptance determination unit that determines, when a call connection request signal from the user terminal is received, whether a call connection request from the user terminal is acceptable, based on an amount of resources that is used by the base station; a redirection-setting unit that sets, when the call connection acceptance determination unit determines that the call connection request from the user terminal is not to be accepted, a different base station to which the user terminal is to be redirected; and a notification unit that reports information representing the different base station that is set by the redirection-setting unit to the user terminal.
摘要:
A base station of a mobile communication system includes a receiver that receives capability information including information regarding plural frequencies which are measurable by the user equipment; an identifying unit that identifies, subsequent to allocation of radio resources to the user equipment, one or more different frequencies which are measurable by the user equipment and different from a frequency of a serving cell, among the plural frequencies in the capability information; and a transmitter that transmits a different frequency measurement command signal for commanding the user equipment to measure the identified one or more different frequencies or all the different frequencies, which are measurable by the user equipment, to the user equipment. The receiver receives a report signal indicating presence or absence of coverage for each of the one or more different frequencies from the user equipment that performs the measurement in response to the different frequency measurement command signal.
