Abstract
PROBLEM TO BE SOLVED: To provide a communication control method master base station secondary base station and user terminal that achieve efficient handover in a duplex connection system.
SOLUTION: A master base station (MeNB) 200M transmits a secondary base station change request message to request change of duplex connection resources at a secondary base station (SeNB) 200S to the SeNB 200S via an X2 interface. The secondary base station change request message includes identification information on a serving gateway (S-GW) 300U connected with the MeNB 200M via an S1 interface. The identification information is an S1 tunnel endpoint ID (S1-TEID) of the S-GW 300U or an IP address of the S-GW 300U.
