Non-public network configuration method and device, CU, DU and base station

Abstract

The embodiment of the invention discloses a non-public network configuration method and device, a CU, DUs, a base station and a computer readable storage medium, and the method comprises the steps that the CU obtains the configuration information of CAG cells of one or more DUs in the base station to which the CU belongs; and the CU informs the DU of the information of the activated CAG cell. According to the embodiment of the invention, the blank of CAG cell configuration in a CU-DU separated network architecture is filled up; the CAG cell configuration of the CU node and the DU node is realized, so that the CU/DU can cooperatively page UE and user initial access based on the CAG cell configuration, and notify other base stations of the CAG cell configuration for inter-base-station resource coordination.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to a non-public network configuration method, device, CU, DU, base station, and computer-readable storage medium. Background technique [0002] NPN (non-public networks, non-public network) means that one or more cell access users in the mobile communication network are restricted and conditional, while ordinary cells can allow all legal subscribers of operators (and roaming user) access. The NPN network can use the concept of CAG (Closed Access Group, closed access user group) for access control. CAG refers to a group of subscribers who are allowed to access one or more specific cells, and the same user can belong to multiple CAGs, each CAG is identified by a CAG ID (Identity, identification). UE (User Equipment, user equipment, also known as terminal) maintains a CAG ID list (allowed CAG ID list) of the CAG to which it belongs, and each CAG cell broadcasts a CAG ID, members of the c...
