HO PKI AS METHOD AND APPARATUS FOR AUTHENTICATION OF ACCESS STRATUM BASED ON PUBLIC KEY INFRASTRUCTURE IN HANDOVER SCENARIO OF NEXT GENERATION WIRELESS COMMUNICATION SYSTEM

摘要

The present disclosure relates to a 5G or 6G communication system for supporting a higher data rate after a 4G communication system such as LTE. A method of operating a serving base station for mutual authentication of an access stratum (AS) section during handover in a wireless communication system according to an embodiment of the present invention comprises the steps of: receiving a measurement report from a terminal; Checking whether the handover condition is satisfied; if the terminal satisfies the handover condition, checking whether a target base station to which the terminal is connected during handover falls within the same authentication area (AA) as the serving base station; , transmitting a handover command configured differently depending on whether the target base station and the serving base station belong to the same AA to the terminal.
