Embodiment 1

[0041] In order to avoid the problem of uneven load of network slice instances during network slice instance configuration and the heavy load of the network slice instance configuration system, this embodiment provides a network slice instance configuration method. The network slice configuration method includes: The analysis module sends network configuration request information; receives network configuration information sent by the network data analysis module; determines the load status of the network slice instance according to the network configuration information, and determines the target network slice instance accessed by the access terminal according to the load status.

[0042] See figure 1 , figure 1 A complete flow chart of a method for configuring a network slice instance provided in this embodiment. When the access terminal needs to access the network, it configures the terminal to the network. figure 1 The network access request is sent for the access and mob...

Embodiment 2

[0068] This embodiment provides a method for sending the load status of a network slice instance. The method for sending the load status of a network slice instance includes: monitoring and analyzing the load status of all network slice instances in the network; When configuring the request information, the network configuration information is returned to the network slice instance configuration module according to the network configuration request information, and the network configuration information includes at least the load status of the corresponding network slice instance.

[0069] See figure 1 , a method for sending the load status of a network slice instance in this embodiment corresponds to figure 1 Actions at the side of the network data analysis module NWDAF.

[0070] In this embodiment, the network slice instance configuration module includes: any one of the access and mobility management module AMF and the network storage library module NRF.

[0071] In this em...

Embodiment 3

[0076] The network slice instance configuration method provided in this embodiment is a specific embodiment in the case where the AMF (Access and Mobility Management Module) actively acquires and subscribes to slice load data from the NWDAF (Network Data Analysis Module).

[0077] see figure 2 , figure 2 Flowchart for AMF (Access and Mobility Management Module) to actively obtain and subscribe slice load data from NWDAF (Network Data Analysis Module).

[0078] figure 2 Including: S01. AMF (access and mobility management module) sends a data analysis request to NWDAF (network data analysis module), requesting load data of slice instances. AMF (Access and Mobility Management Module) can request load data of all slice instances in the current network from NWDAF (Network Data Analysis Module), or only request load data of some slice instances.

[0079] S02. The AMF (access and mobility management module) receives the data analysis result returned by the NWDAF (network data a...

Abstract

The embodiment of the invention provides a network slice instance configuration method and device. The method comprises the following steps: sending network configuration request information to a network data analysis module; receiving network configuration information sent by the network data analysis module; determining a load condition of the network slice instance according to the network configuration information, and determining a target network slice instance accessed by the access terminal according to the load condition. Network configuration information is actively acquired from a network data analysis module through a network slice instance configuration side, and a network slice instance accessed by an access terminal is configured through a load condition of the network slice instance in the network configuration information. The access terminal is prevented from accessing the network slice instance with a large load, so that the load of the network slice instance is more uniform; meanwhile, the load conditions of the plurality of network slice instances can be obtained, and the network slice instance configuration side directly performs configuration when the network slice instances are configured, so that the load of the network slice instance configuration system is reduced.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the field of communication technologies, and in particular, relate to but are not limited to a method and device for configuring a network slice instance. Background technique [0002] In the fifth-generation mobile communication system, the concept of network slicing is introduced. When a user accesses the network and establishes a PDU (protocol data unit), a suitable network slice instance is selected to establish a PDU (protocol data unit), and subsequent data business. On the network side, the same type of network slice can have multiple slice instances. In addition to the current DNN, S-NSSAI (Single Network Slice Selection Auxiliary Information), location and other factors, the selection of a slice instance can also refer to the media plane of the slice instance. Packet traffic and load, etc. [0003] The current standard introduces NWDAF (Network Data Analysis Module), a net...
