Document Type and Number:
WIPO Patent Application WO/2023/013954
Kind Code:
A1
Abstract:
According to one embodiment of the present disclosure, a method for controlling a secondary base station change comprises a step in which a secondary base station central unit receives a first control message from a main base station, transmits a plurality of second control messages to secondary base station distribution units, receives a plurality of third control messages from the secondary base station distribution units, and transmits, to the main base station, a fourth control message including a first container and a second container, wherein the first container includes a plurality of cell group configurations and the second container includes one NR control message.
