Embodiment 1

[0042] This embodiment provides a cell communication control method that enables a terminal to maintain connections with multiple CAG cells at the same time, see figure 1 shown, which includes:

[0043] S101: When the target network element determines that at least two CAG cells need to be used to provide connection services for the terminal, apply for cell resources of corresponding CAG cells for the terminal.

[0044] It should be understood that, the target network element in this embodiment determines the number of CAG cells that need to be used by the terminal, which may be flexibly determined according to the current requirements of the terminal and / or other factors. In addition, the target network element in this embodiment may be a CU, or a base station or the like. The cell resources applied for in this embodiment may include, but not limited to, physical parameters of the cell, service bearer parameters, and the like.

[0045] S102: The target network element sends...

example 1

[0050] The target network element receives the handover request message sent by the source network element (such as the source base station) corresponding to the terminal, and according to the handover request message determines that at least two CAG cells need to be used to provide connection services for the terminal, and applies for at least two CAG cells for the terminal. The cell resource of the CAG cell.

[0051] In this example, the above handover request message may carry first configuration information, and the first configuration information includes but is not limited to at least one of the following:

[0052] Target candidate cell identification;

[0053] CAG ID of one or more CAG cells supported by the terminal;

[0054] When the target candidate cell includes a CAG cell, it is the CAG membership information of the target candidate cell of the CAG cell, and the CAG membership information is used to indicate whether the terminal user is a CAG member of the CAG cell....

example 2

[0068] In this example, the target network element determines whether at least two CAG cells need to be used to provide connection services for the terminal according to the terminal measurement report.

[0069] For example, when the target network element has currently provided at least one CAG cell connection service for the terminal and determines that N CAG cells need to be added for the terminal to provide connection services for the terminal according to the terminal measurement report of the terminal, apply for N corresponding CAG cells for the terminal Cell resources, where N is an integer greater than or equal to 1; and when the terminal measurement report includes a CAG cell, it includes CAG membership information of the CAG cell.

[0070] In an application scenario in this example, the target network element is the target CU, and the target CU can pass the terminal according to the terminal measurement report (for example, the measurement quality information of multi...

Abstract

The embodiment of the invention provides a cell selection and communication control method and device, a network element, a terminal and a storage medium, and the method comprises the steps: enablinga target network element to apply for the cell resources of a corresponding CAG cell for the terminal when the target network element determines that at least two CAG cells need to be used for providing a connection service for the terminal at present; sending the applied cell resources to the terminal; therefore, the terminal can be connected with at least two CAG cells at the same time, the terminal can be connected with a plurality of CAG cells at the same time, and compared with the prior art that only the terminal and one CAG cell are connected in a single mode, the cell connection mode is enriched, and the communication performance and the satisfaction degree of user experience are improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a cell selection and communication control method, device, network element, terminal and storage medium. Background technique [0002] In related technologies, Non-Public Networks (Non-Public Networks, NPN) means that one or more cells in the mobile communication network have restricted and conditional access to users, while ordinary cells allow all Access by legitimate subscribers (and roaming users). 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. [0003] The 5G network architecture is innovative and flexible in networking. In the 5G network, the base station can be separated into two functional entities: a Centralized Unit (CU) and a Distributed Unit (DU). ...
