Wireless resource allocation method based on network slices

Abstract

The invention provides a wireless resource allocation method based on network slices. A centralized wireless resource manager periodically allocates wireless resources to each slice in a network, and sends information of the wireless resources allocated to each slice to a wireless resource manager of each slice; the wireless resource manager of the slice allocates the wireless resources to each terminal equipment in the slice, and periodically performs distributed negotiation based on a matching process with the wireless resource managers of other slices in the network; resources of the matched slices are shared finally; furthermore, the wireless resource manager of a resource contribution slice periodically adjusts the proportion of the shared resources in the resource pool of the slices to dedicated resources; and in addition, the wireless resource manager of each slice also can re-allocate the wireless resources of the slices between the terminal equipment so as to be suitable for the time-varying performance of a channel and the mobility of the terminal equipment. Due to autonomous management of the wireless resources by the slices, the load pressure of the centralized wireless resource manager is reduced.

Description

Technical field [0001] The present invention relates to wireless communication technology, in particular to a wireless resource allocation method based on network slicing. Background technique [0002] In recent years, the continuous emergence of various new technologies and new services has placed higher demands on wireless access networks. For example, virtual reality (Virtual Reality, VR) technology requires lower latency, and driverless car technology requires the network to provide higher reliability. In order to meet these differentiated needs, the traditional method of operators is to purchase specialized software and hardware equipment for each type of business. However, this method will bring high costs and make network maintenance extremely complicated. [0003] In order to solve the above-mentioned problems, network slicing technologies based on Network Function Virtualization (NFV) and Software Defined Network (SDN) have emerged. Specifically, a physical network can b...

Problems solved by technology

Although this resource allocation method has a good effect, due to the time-varying channel environment and the mobility of terminal equipment, etc., the centralized wireless resource manager needs to frequently collect the latest global information for timely resource adjustment, which will hinder the centralized wireless resource management. When the number of terminal devices in the network is large, allocating specific resources to each terminal device will also bring a large computational burden to the centralized wireless resource manager.
