Communication method, network device, terminal device and system

Abstract

The invention provides a communication method, a network device, a terminal device and a system. The communication method includes the following steps that: an RAN device acquires the information of at least one RAN network slice identifier; and the RAN device sends first information to a terminal device, wherein the first information contains the at least one RAN network slice identifier, whereinthe at least one RAN network slice identifier is in a corresponding relation with a core network slice identifier. According to the communication method, the network device, the terminal device and the system provided by the embodiments of the present invention, the information of the RAN network slice identifiers is adopted to perform communication, so that communication efficiency can be improved.

Description

technical field

[0001] The present application relates to the communication field, and more specifically, to a communication method, network device, terminal device and system. Background technique

[0002] Network slicing technology has been proposed as a key technology for future communication system research, enabling future networks to support rich services to serve various industries in society. For example, enhanced mobile broadband (eMBB) services represented by virtual reality and augmented reality, and ultra-reliable and low-latency (URLLC) services represented by autonomous driving and industrial control , and the massive machine type of communication (mMTC) business represented by intelligent logistics and sensors will greatly expand the service scope of the communication system.

[0003] The existing communication system puts all network services in a common transmission channel, which will not be able to meet the hugely different Quality of Service (QoS) requir...

Embodiment Construction

[0101] The technical solution in this application will be described below with reference to the accompanying drawings.

[0102] Before introducing the communication method, device, and system of the present application, some terms appearing in this paper are firstly described in order to facilitate the understanding of the content of the present application.

[0103] Network slice (Network slice): refers to a logical network with different network capabilities and network characteristics customized according to different service requirements or tenants on the physical or virtual network infrastructure. Network slicing can be a complete end-to-end network including terminal equipment, access network, transmission network, core network and application server, capable of providing telecommunication services and having certain network capabilities. Network slicing can also be any combination of the above-mentioned terminal equipment, access network, transmission network, core netw...
