Embodiment Construction

[0083] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0084] For most MEC scenarios, devices and users on edge sites can only access services within the signal coverage of edge base stations (or MEC servers). When they are moved out, they have to reconnect to another MEC server or cloud server, resulting in QoS degradation or service interruption. Therefore, considering the randomness of user mobility, how to se...

Abstract

An embodiment of the present application provides a method and device for dynamic service migration, the method includes: according to the movement state of the target mobile user currently at the border of the first edge server, obtaining the location where the target mobile user moves from the coverage area of ​​the first edge server to The probability of the coverage of the second edge server; and obtain the total cost of migration required for the service corresponding to the target mobile user to move from the first edge server to the coverage of the second edge server; construct Markov according to the probability and the total cost of migration Decision-making process, and iteratively solve the linear equation corresponding to the Markov decision-making process to obtain the corresponding target dynamic service migration strategy. On the basis of effectively reducing the transmission delay in dynamic communication service migration, this application can also effectively balance the cost of migration data, and then provide a more optimal service migration decision, that is, it can effectively improve the dynamic communication service migration of mobile users accuracy and reliability.

Description

technical field [0001] The present application relates to the technical field of information processing, and specifically relates to a dynamic service migration method and device. Background technique [0002] With the popularity of mobile terminals and the Internet of Things (IoT), Mobile Edge Computing (MEC), as a new architecture that uses mobile base stations to extend cloud computing services to the edge of the network, has emerged as the times require. It integrates cloud computing and mobile computing technologies, and transfers some applications, data and services from centralized cloud data centers to the edge of the network where edge servers are deployed. Since local edge servers are closer to users and IoT devices than centralized cloud data centers, QoS (such as response time and throughput) and privacy can be improved and overhead can be reduced. Therefore, Mobile Edge Computing (MEC) is becoming more and more popular in supporting various innovative applicati...
