Communication method, device and system

Abstract

The invention provides a communication method, device and system. The method comprises: a first policy control network element sends a subscription message to a usage monitoring network element, the subscription message comprising identification information of a first slice and identification information of terminal equipment, the subscription message being used for subscribing to usage state information of the terminal equipment in the first slice; the first policy control network element receives first indication information from the usage monitoring network element, the first indication information being used for indicating that the usage of the terminal equipment in the first slice is exhausted; the first policy control network element sends availability state information of the first slice to a mobility management network element, the availability state information being used for indicating that the first slice is unavailable; or the first strategy control network element sends a user route selection strategy to the terminal equipment, the user route selection strategy not comprising the identification information of the first slice. Based on the scheme, when the usage of the terminal equipment in the first slice is exhausted, the terminal equipment can be prevented from using the service of the first slice, and correct communication can be realized.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202010143072.7 and the application title “Communication Method, Device and System” filed with the China Patent Office on March 04, 2020, the entire contents of which are incorporated herein by reference. technical field [0002] The present application relates to the technical field of communication, and in particular to a communication method, device and system. Background technique [0003] In the prior art, when a terminal device uses a slice, there may be a quota limit, for example, the quota of the terminal may be limited to be equal to the quota of the slice, or equal to the quota of the slice multiplied by a percentage. [0004] When the usage of a terminal device reaches the quota, if the terminal device continues to use the slice, an error may occur. Contents of the invention [0005] The present application provides a communication method, device and system, ...
