Abstract

The invention discloses a system state-based task scheduling method. The method comprises the steps that in a coverage range of an MEC server, a user initiates a task request to the server, and the task request enters a task queue of a buffer region of the server to perform queuing; the server performs scheduling on the task request in the task queue, and the task request is processed through a calculation mode of the server or a calculation mode of a mobile device of the user; for scheduling of the processed task request, different scheduling policies are selected according to different conditions of a system state; the server updates the system state every a period of time and performs selection on the scheduling policies; the scheduling policy which enables a communication data quantity to be minimal is searched for according to a formula; the server selects the optimal scheduling policy and selects an MEC calculation mode or a local calculation mode to process tasks. According to the method, the communication data quantity is reduced by utilizing calculation and storage resources of the mobile device of the user; the task processing delay is optimized; the service quality of the user is improved; and the server burden is reduced.

Description

technical field [0001] The invention relates to the field of communication data processing, in particular to a task scheduling method based on system state. Background technique [0002] Due to the industrialization of mobile devices such as smartphones and tablet computers, the number of mobile Internet applications based on mobile devices has also shown explosive growth. These applications will generate a large amount of communication data, and will also cause huge consumption of computing resources. In order to solve the above problems, the mobile communication industry has proposed the concept of Mobile Edge Computing (MEC). MEC is an emerging model that provides users with computing and storage resources by setting up mobile edge computing servers at the edge of the mobile wireless access network. The MEC server can transfer part of the computing tasks of users within the coverage area to the MEC server for computing, and use the powerful computing resources of the MEC...
