Network slice configuration method, network slice configuration device, radio access network RAN node and terminal

Abstract

The invention provides a network slice configuration method, a network slice configuration device, a radio access network RAN node and a terminal, wherein the method comprises the steps of: sending basic slice configuration information to the terminal, so that the terminal reports pre-configured network slice selection assisted information used for network slice selection; and, according to the network slice selection assisted information, sending a target message to the terminal, so that the terminal determines a target RAN slice in multiple alternative RAN slices corresponding to each supported core network CN slice according to the target message. By means of the network slice configuration method, the network slice configuration device, the radio access network RAN node and the terminal provided by the invention, multiple CN slices are mapped to an RAN slice, so that one RAN node can support a lot of CN slices; therefore, the radio resources of the RAN node can be saved; and furthermore, the processing capability of the RAN node can be improved.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular to a network slice configuration method and device, a radio access network RAN ​​node and a terminal. Background technique [0002] The new generation communication system introduces a network slicing (network slicing) technology, which allows a network, a core network (Core Network, CN) and a radio access network (Radio Access Network, RAN) to be divided into multiple slices (slices). Different services are transmitted in different slices without interfering with each other. The billing policy, security policy, and service quality policy of each slice may be different. [0003] In related technologies, there is still a one-to-one mapping relationship between CN slices and RAN slices, but the update domain of CN slices is in a location area, and there may be a lot of CN slices in a location area, which means that a RAN node can support The number of CN slice slices is very l...

AI Technical Summary

Problems solved by technology

If one-to-one mapping between RAN slices and CN slices is required, a RAN node cannot support it due to its limited wireless resources and processing capabilities

This will cause the RAN isolation performance of many CN slices to vary greatly due to different RAN nodes
