MOBILE STATION AND RADIO BASE STATION

摘要

A DRX state of a mobile station UE is flexibly changed. In a mobile station UE according to the invention, in a case where a reception state of the mobile station UE is managed as a continuous reception state, and even in a case where the reception state of the mobile station UE is configured to be capable of transitioning to a Short-DRX state, a control unit 22 transitions the reception state of the mobile station UE to a Long-DRX state without transitioning the reception state to the Short-DRX state when an instruction to transition the reception state of the mobile station UE to the Long-DRX state is made via MAC-CE by a radio base station.

1. A mobile station, comprising:
a control unit configured to manage a reception state of the mobile station as any one of a continuous reception state, a first discontinuous reception state in which discontinuous reception is performed in a first discontinuous reception cycle and a second discontinuous reception state in which discontinuous reception is performed in a second discontinuous reception cycle which is a cycle longer than the first discontinuous reception cycle, wherein in a case where the reception state of the mobile station is managed as the continuous reception state, the control unit transitions the reception state of the mobile station to the first discontinuous reception state when fulfillment of a first condition is detected, in a case where the reception state of the mobile station is managed as the first discontinuous reception state, the control unit transitions the reception state of the mobile station to the second discontinuous reception state when fulfillment of a second condition is detected, and in a case where the reception state of the mobile station is managed as the continuous reception state, and even in a case where the reception state of the mobile station is configured to be capable of transitioning to the first discontinuous reception state, the control unit transitions the reception state of the mobile station to the second discontinuous reception state without transitioning the reception state to the first discontinuous reception state when an instruction to transition the reception state of the mobile station to the second discontinuous reception state is made via a control element in a MAC layer by a radio base station.
