Fog computing network service transmission method based on grading caching

Abstract

An embodiment of the invention discloses a fog computing network service transmission method based on grading caching. The method comprises the steps as follows: first F-UE (Fog computing-User Equipment) generates a service request, and the first F-UE responds to the service request; the service request is sent to a first F-AP (Fog computing-Access Point) if the F-UE itself cannot respond to the service request; the first F-AP instructs other F-UE connected with the first F-AP to respond to the service request; the first F-AP itself responds to the service request if other F-UE cannot respond to the service request; the service request is sent to a centralized processing center if the first F-AP itself still fails to respond to the service request; the centralized processing center instructs other F-AP connected with the centralized processing center to respond to the service request; data service is obtained from a large-scale centralized cache to respond to the service request if other F-AP cannot respond to the service request; data service is obtained from a data center to respond to the service request if the data service obtained from large-scale centralized cache still cannot respond to the service request. With the adoption of the provided embodiment, efficient and reliable data service transmission is realized.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a service transmission method based on a hierarchical cache in a fog computing network. Background technique [0002] Cloud radio access network is a new energy-efficient network architecture that enables communication operators to provide users with high data rate services. The cloud wireless access network architecture mainly includes three components: traditional access points, centralized cloud baseband processing pools, and outbound links connecting traditional access points and centralized cloud baseband processing pools; among them, traditional access points Mainly RRH (Remote Radio Head, remote radio frequency unit). [0003] In the prior art, the basic data processing flow of the cloud wireless access network is as follows: After receiving the data service request sent by the user terminal, the RRH directly uploads the data service request to the centralize...
