Problems solved by technology

[0006] Although the 5G network architecture defined by 3GPP allows a terminal device to access and use multiple network slices at the same time, it restricts the use of different application identifiers for terminal devices to access different network slices, that is, an application-related service message can only use a single network slices for message transmission, which cannot meet the needs of a single industry application using multiple network slices for communication; in addition, the existing technology does not solve the problem of how to select an appropriate network slice for downlink communication between industry applications or IoT platforms and terminal devices

Abstract

The invention provides an Internet of Things service routing method. A mapping relationship between a service feature and a network slice is established on an Internet of Things platform; or establishing a routing strategy for determining the network slices according to the service characteristics, so that the Internet of Things platform can select a proper network slice to send the service message to the terminal equipment according to the service characteristics of the service message sent by the industry application, thereby meeting various network requirements of the industry application.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method, device and system for Internet of Things service routing. Background technique [0002] In the next-generation mobile communication network architecture (ie, 5G network architecture) formulated by the 3rd Generation Partnership Project (3GPP) standards organization, the physical network can be abstractly divided into multiple network slices, and each network slice constitutes a End-to-end logical networks are logically isolated from each other. Each slice can flexibly provide one or more network services according to the requirements of the demand side, and does not affect each other with other slices in the network. [0003] In order to support various services of customers, such as enhanced mobile broadband (eMBB) services represented by high-definition video and virtual reality, ultra-reliable low-latency communication (Ultra-reliable and Low-latency Communi...
