Abstract
PROBLEM TO BE SOLVED: To provide a master base station and a secondary base station that implement efficient handover in a dual connectivity scheme.
SOLUTION: A communication control method in a mobile communication system supports dual connectivity communication using a master base station for establishing RRC connection with a user terminal 100 and a secondary base station 200S for providing additional radio resources to the user terminal. The communication control method comprises an inter-master base station handover procedure for performing handover of the user terminal from a source master base station 200M1 to a target master base station 200M2 without changing the secondary base station.
