SECURITY ON THE ACCESS LEVEL IN WIRELESS COMMUNICATIONS Russian patent published in 2021 - IPC H04W12/02 

FIELD: wireless communications.

SUBSTANCE: radio access network (RAN) node (12) configures security at an access-related layer (AS) in the user plane in a wireless communication system (10), which includes a radio access network (RAN) (10B) and a core network (10A) (CN). The RAN node (12) is configured to receive signaling (20) from CN (10A), which indicates a decision by CN (10A) as to whether or not the RAN node (12) should activate AS security in user plane, and which indicate whether or not the RAN node (12) is allowed to reject the decision by CN (10A). For example, signaling (20) may indicate whether the CN decision is a command that the RAN node (12) should match or a preference that the RAN node (12) is allowed to reject. Independently, the RAN node (12) can also be configured to activate or not activate AS security in the user plane, depending on the signaling (20).

EFFECT: technical result consists in increasing the flexibility of resource allocation at the access level (AS) in the user plane.
