Claim 20:
21. A method in a communication system which comprises an entity for managing mobility of a user equipment (UE), a first base station, and a second base station, the method comprising:
identifying, by the entity, a total aggregate maximum bit rate (AMBR) of the UE (UE-AMBR) based on a subscribed UE-AMBR;
transmitting, by the entity to the first base station, an initial context setup request message including the total UE-AMBR;
determining, by the first base station, a first base station UE-AMBR and a second base station UE-AMBR based on the total UE-AMBR;
transmitting, by the first base station 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
transmitting, by the second base station to the first 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.
