AI Technical Summary
Technical Problem
In the context of 6G wireless communication systems, the DU (Distributed Unit) may have an RRC entity, making it challenging to ensure proper security protection for RRC messages due to the lack of access to security information like security keys, which existing security protection procedures cannot address.
Method used
The implementation of a radio base station with a control unit that acquires security information from the core network and transmits it to the DU, enabling encryption and integrity protection for RRC messages directly at the DU level.
Benefits of technology
Ensures reliable security protection for RRC messages even when RRC entities are located in the DU, maintaining communication security in the 6G wireless network.
