AI Technical Summary
When existing wireless communication systems switch between PC5 paths and Uu paths, they cannot ensure consistency of security policies, resulting in communications that may be intercepted, tampered or damaged, and there is no effective way to solve these security problems.
During the path switching process, the signaling integrity protection policy is set to REQUIRED based on the path switching policy associated with the service, and the consistency of the UP security protection policy is maintained on the PC5 and Uu paths to ensure the security of communication.
It realizes reliable protection of signaling and data during path switching, prevents malicious attacks and tampering, and ensures the security and continuity of communication.
