BASE STATION AND METHOD FOR SUPPORTING SELF-CONFIGURATION AND SELF-OPTIMIZATION

Document Type and Number:

WIPO Patent Application WO/2023/234664

Kind Code:

A1

Abstract:

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A base station and a method for supporting self-configuration and self-optimization are provided. The method includes sending, by a main node (MN), a secondary node (SN) addition request message to a target candidate SN, receiving, by the MN, an addition request acknowledgment message from the target candidate SN, sending, by the MN, a radio resource control (RRC) reconfiguration message to a user equipment (UE), receiving, by the MN, an RRC reconfiguration complete message from the UE, which is an RRC reconfiguration complete message sent by the UE after accessing a candidate secondary cell group primary cell (PSCell), sending, by the MN, an SN release request message to a source SN, receiving, by the MN, an SN release request acknowledgment message from the source SN, wherein the release request acknowledgment message includes secondary cell group (SCG) UE history information, updating, by the MN, saved UE history information, sending, by the MN, UE history information to a target SN.
