Embodiment Construction

[0038]In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0039]In NR and similar systems, a logical RAN node can be further divided into a CU-CP, one or more CU-UPs, and one or more distributed node DUs. This structure is called a CU-CP / UP separation structure . In this structure, CU-CP and DU are connected by F1-C or similar interface, and CU-CP and CU-UP are connected by E1 or similar interface;...

Abstract

Provided are a safety algorithm configuration method, a control plane center node and a terminal. The method comprises the steps of sending safety algorithm information corresponding to a user plane center node CUUP to the terminal, implementing a negotiation process of the safety algorithm information corresponding to the CUUP, implementing that the CUUP can correspond to its own safety algorithminformation, and implementing the negotiation process of the safety algorithm information corresponding to the CUUP. The safety of the CUUP service is improved.

Description

Technical field[0001]The present invention relates to the field of communication technology, in particular to a security algorithm configuration method, a control plane central node and a terminal.Background technique[0002]In the New Radio (NR) system, a logical radio access network (Radio Access Network, RAN) node can be further divided into a Central Unit-ControlPlane (CU-CP), one or more A user plane central node (Central Unit-User Plane, CU-UP) and one or more distributed nodes (Distributed Unit, DU), this structure is called CU-CP / UP separation structure, these nodes can be located in different physical Within the entity. In addition, one CU-CP can be connected to multiple CU-UPs.[0003]In addition, in the prior art, the security algorithm used by all user bearers between a user and a 5g base station (gNB) is the same (including encryption algorithms and integrity protection algorithms). In this scenario, if user data of different Quality of Service (QoS) is carried on the CU-UP...
