PROBLEM TO BE SOLVED: To provide a mobile communication method and a radio base station that are able to prevent a problem involved in an extended off period in the case where an extended DRX period is configured.SOLUTION: In an RRC connected state of RRC connection being set between a radio terminal 10 and a radio base station 110, a DRX period (intermittent reception period) is configured that includes an on period when a downlink signal transmitted by a serving base station should be monitored and an off period other than the on period S210. In the case of the DRX period being configured, the radio terminal 10 sends the radio base station 110 a timing adjustment request uplink signal via an uplink control channel even if a radio resource for an uplink data channel is not allocated S230. |
