Embodiment

[0023] Such as figure 1 As shown, in the present invention, the distributed edge computing service system is composed of three types of nodes: the local edge node set serving mobile terminals, the adjacent edge node set and the cloud computing center node set. local edge node (N local ) consists of the MEC (Mobile Edge Computing) server deployed in the wireless base station in the local wireless network area where the terminal is located. It is located in the wireless cellular network area connected to the terminal and is the edge computing node of the base station. This node constitutes the terminal Edge computing local service system; adjacent edge nodes (assuming that there are k-1 adjacent edge nodes in total, forming the adjacent edge node set N near ={N 1 , N 2 ,...,N k-1}), deployed in the base station adjacent to the wireless network area, connected with the local edge node by high-speed dedicated line network, it is a set of edge nodes that can be scheduled and us...

Abstract

The invention relates to the field of mobile edge calculation and particularly relates to a user terminal task unloading method of an edge computing service system. The method comprises the followingsteps that: a local edge node receives a task unloading request of a local terminal, acquires computing resource use information of the local edge node, and adopts a local resource priority strategy based on a resource threshold according to a resource condition required by the task and a resource use condition of the currently available edge node; the local edge node requests confirmation from the selected edge node or a computing node and executes the task; and the edge node or the computing node bearing the task returns a task execution result to the terminal, and sends a task execution record to the cloud computing center. According to the method, the local edge nodes decide to unload task allocation, and the rationality and balance of resource use among the edge computing nodes are optimized under the condition that the user experience quality and the service quality are guaranteed.

Description

technical field [0001] The invention relates to the field of mobile edge computing, in particular to a user terminal task offloading method of an edge computing service system. Background technique [0002] With the rapid development of the mobile Internet, mobile user devices continue to proliferate, such as smartphones, tablet computers, smart homes, and IOT devices. The application scenarios of these devices are becoming more and more abundant, resulting in many computing-intensive usage scenarios, such as VR, AR, and intelligent recognition. However, due to its portability, mobile user equipment is restricted by computing power and battery life. With the development of cloud computing technology, cloud computing capabilities are used to give mobile devices more powerful computing power to meet application needs. However, the general cloud computing cluster is far away from the mobile user equipment, resulting in a large communication delay. It is difficult for these c...
