1. A method, performed by a user device configured to communicate with a first base station and a second base station, for managing communication of a segmented radio resource control, RRC, message that includes N segments, the method comprising:
dividing, by an RRC layer of the user device, a first RRC message into the N segments of the segmented RRC message;
transmitting at least M segments of the segmented RRC message to the first base station, M being an integer greater than zero and less than N;
receiving from the first base station a second RRC message that configures the user device to hand over from a cell of the first base station to a cell of the second base station; and
after receiving the second RRC message, transmitting all segments of the segmented RRC message to the second base station.
