Kind Code:
B2
Abstract:
The present invention is designed to optimize the operation for starting data communication when traffic is produced on the base station side in dual connectivity A structure is provided in which, when a user terminal (20) is in DRX mode in a first carrier that is used in a secondary base station (12), a master base station (11) communicates with the user terminal by using a second carrier, and, when traffic is produced in in the subject station or in the secondary base station, transmits command information for allowing the user terminal to transition from DRX mode to non-DRX mode, to the user terminal.
