Claim 10:
11. A first base station in a communication system, the first base station comprising:
a transceiver; and
a controller configured to:
control the transceiver to receive, from an entity for managing mobility of a user equipment (UE), an initial context setup request message including a total aggregate maximum bit rate (AMBR) of the UE (UE-AMBR);
determine a first base station UE-AMBR and a second base station UE-AMBR based on the total UE-AMBR;
control the transceiver to transmit, to a second base station, a request message for dual connectivity, the request message including the second base station UE-AMBR, and information on a radio access bearer to be established; and
control the transceiver to receive, from the second base station, a response message in response to the request message,

wherein the first base station UE-AMBR and the second base station UE-AMBR are enforced by the first base station and the second base station, respectively.
