Embodiment Construction

[0198] figure 1 It is a schematic diagram of a communication system. Such as figure 1 As shown, the system includes: DU, a control plane (CU-Control Plane, CU-CP) of the centralized unit, and a user plane (CU-User Plane, CU-UP) of the centralized unit.

[0199] Such as figure 1 As shown, the system may be a network device system, which is composed of one CU-CP, multiple DUs, and multiple CU-UPs. Among them, CU-CP and DU can be connected through F1-C interface, between CU-UP and DU can be connected through F1-U interface, between CU-UP and CU-CP can be connected through E1 interface.

[0200] Among them, the DU covers the physical layer of baseband processing and some functions of the media access control (Media Access Control, MAC) layer / radio link control (Radio Link Control, RLC) layer. Considering the transmission resources of the Radio Remote Unit (RRU) and the DU, some physical layer functions of the DU can be moved up to the RRU. With the miniaturization of RRUs, ev...

Abstract

The present application provides a security negotiation method and device. The method includes: the terminal receives the security negotiation information sent by CU‑CP / CU‑UP, the security negotiation information includes: the integrity protection indicator of CU‑UP; The integrity protection indicator of the CU‑UP described above determines whether to enable the user plane integrity protection of the terminal. In the scenario where CU‑CP and CU‑UP are separated, the user plane security negotiation with the terminal can be completed.

Description

technical field [0001] The present application relates to the field of wireless communication, in particular to a security negotiation method and device. Background technique [0002] The basic processing unit of the future network on the access network side is split into a centralized unit (Centralized Unit, CU) and a distributed unit (Distributed Unit, DU), where the centralized unit can be split into a control plane functional entity and a user plane Functional entities correspond to control plane functional network element devices and user plane functional network element devices. Specifically, this functional decoupling is mainly for further functional splitting of the centralized unit of the access network device. In order to ensure communication security in this scenario, an effective access security negotiation mechanism needs to be provided. [0003] However, the current security negotiation mechanism is mainly an authentication server (Authentication Server, AS) ...
