1. A method in a User Equipment (UE) for managing radio bearers, the method comprising:
communicating, by the UE, with a first base station over a signaling radio bearer 4 (SRB4) associated with a dedicated control channel and configured to carry at least application-layer measurement reporting information, the SRB4 associated with a logical channel identity;
receiving, by the UE and from a radio access network (RAN) including the first base station and a second base station, a message related to a data radio bearer (DRB) having the logical channel identity and terminated at the second base station; and
releasing, by the UE, the SRB4 in response to the message.
