Method and apparatus for selecting selective security mode and flow management in a wireless communication system

Abstract

The disclosure relates to a fifth generation (5G) communication system or a sixth generation (6G) communication system for supporting higher data rates beyond a fourth generation (4G) communication system such as long term evolution (LTE). A method performed by a core network entityfor selecting a selective security mode for applying selective security is provided. The method receives first information block from RAN. The first information block includes UE capability to support selective security and preferred selective security mode. Further, core network entity may determine if RAN and core network entity are capable of supporting the preferred selective security mode. Finally, the core network entity applies the preferred selective security on the one or more incoming data packets based on the encryption status of the incoming data packets, when at least one of RAN and core network entity supports the preferred selective security mode.
