Embodiment Construction

[0119] The present application provides a network slice selection method and device, which are used to select a suitable network slice for a terminal when the terminal does not report network slice related information. Among them, the method and the device are based on the same or similar idea of ​​the same invention. Since the method and the device have similar problem-solving principles, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated. In the description of the embodiments of the present application, "and / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which may mean: A exists alone, A and B exist simultaneously, and There are three cases of B. The character " / " generally indicates that the contextual objects are an "or" relationship. The at least one involved in this application refers to one or more; a...

Abstract

The invention discloses a network slice selection method and a network slice selection device, which are used for selecting a network slice for a terminal without the capability of reporting NSSAI. The method comprises the following steps that an access and mobility management function AMF sends a slice selection request to a network slice selection function NSSF, the slice selection request is used for requesting to select a network slice for a service of a terminal, the slice selection request carries dynamic feature information of the terminal, and the dynamic feature information is used for selecting the network slice; and the AMF receives the identification information of the network slice from the NSSF.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for selecting a network slice. Background technique [0002] The fifth-generation mobile communication (the 5th-generation, 5G) system adopts network slicing technology. Network slicing is a combination of hardware, software, policies and spectrum dynamically deployed by network operators to meet the quality of service of a specific user set from a business perspective. kind of combination. Network slicing provides terminals with end-to-end network services from the radio access network to the core network. Specifically, in a network that supports slicing technology, network functions are divided into multiple virtual network function (virtual network function, VNF) modules, and each VNF module can be used to perform different network functions, such as sorting, segmentation, encryption and decryption By dynamically ...
