The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A user equipment (UE) receives secondary security key update information for one or more candidate cells for secondary cell group (SCG) primary secondary cell (PSCell) change. UE receives a cell switch command for a secondary cell group (SCG) PSCell change and performs the cell switch from a serving cell to a target cell. For the target cell, UE performs a security key update based on the secondary security key update information. UE receives a secondary security key update identifier for each candidate cell and maintains a variable to store a secondary security key update identifier for the serving cell. If the secondary security key update identifier of the target cell is different from that of the serving cell, UE performs a security key update for the cell switch.
