Abstract

The invention relates to a virtual resource distribution method based on a self-backhaul small cellular network, and belongs to the technical field of mobile communication. The method comprises the steps: obtaining the usable virtual resource information of each base station, the user state information and slicing demand information through a virtual network manager, wherein the user state information comprises user channel quality information and buffering queue information, so as to distribute virtual resources to a user served by each service provider, and dynamically adjusting the band proportion, used for wireless backhaul, of a self-backhaul small base station. Meanwhile, the method guarantees the demands of each service provider for the minimum mean speed, the system stability and small cellular backhaul capacity. The method achieves the purpose of making the most of the band resources, also reduces the processing time delay of the user at the small base station, and can maintain the stability of a system queue while improving the mean benefits of the service providers.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a virtual resource allocation method based on a self-backhauled small cell network. Background technique [0002] With the rapid increase in the number of mobile users and the widespread popularization of smart terminals, next-generation network technologies need to provide higher system capacity, spectrum utilization, and lower latency. Therefore, wireless network virtualization technology has emerged as the times require. In a wireless network virtualization scenario, traditional operators are decoupled into two independent roles: an infrastructure provider (Infrastructure Provider, InP) and a service provider (ServiceProvider, SP). InP abstracts and slices physical resources in the network (including spectrum, power, antenna, backhaul, etc.) to provide SPs with virtual networks with different requirements; SPs can lease physical resources from different InPs to pr...
