Mobility management method and system for mobile edge computing

Abstract

The invention discloses a mobility management method and system for mobile edge computing. The method comprises the following steps that a change of an IP address of UE is acquired to obtain a changeof a bearing path, and a position change of the system UE is determined by analyzing a data packet; after target MEC acquires a bearing change of the system UE, the system UE is guaranteed to continuously use services of an MEC application in a process of moving in different MEC regions; the mobile edge computing application is migrated from system source MEC to system target MEC according to a migration decision; after the system migration is completed, the system target MEC carries out routing update and provides a local mobile edge computing service for the system UE; and the system targetMEC provides services for the system UE and sends a notification to the system source MEC simultaneously, and the system source MEC determines whether to be closed or not according to a use conditionof a system application. According to the method, the energy optimization can be effectively realized on the premise of guaranteeing the customer service quality.

Description

technical field [0001] The present invention relates to the technical field of mobility management decision-making, in particular to a mobility management method and system for mobile edge computing. Background technique [0002] The explosive growth of traffic in today's world, the near real-time response time required by virtual reality and the massive number of connections required by the Internet of Things have also exceeded the capacity of existing networks. In order to meet the above challenges, the industry has adopted MEC (Mobile Edge Computing) in the 5G mobile network. [0003] According to the definition of ETSI (European Telecommunications Standards Institute), MEC provides IT and cloud computing capabilities for the radio access network by deploying general-purpose servers in the radio access network. The MEC system allows mobile devices to offload computing tasks to network edge nodes, such as base stations and wireless access points, so that services can be l...

Problems solved by technology

[0013] The first limitation of existing technology 2 is that the modeling of user movement is too simple, and the movement of users on a two-dimensional plane cannot be simply equivalent to a one-dimensional model

The second limitation is that it is unscientific to treat the two types of costs of the system as constants. The farther the distance between the user and the MEC, the communication cost should increase accordingly.
