基于MEC的5G无线能力开放系统研究

Research on 5G Wireless Capability Open System Based on MEC

移动边缘计算(MEC)在5G移动通信网络中扮演着重要角色,构建在5G接入网侧,靠近移动终端用户,可以有效解决5G网络对高带宽和低延时的需求。移动边缘计算(MEC)获取基站无线测量信息和空口调度信息,进行策略加工,以无线网络能力APIs形式开放给移动边缘应用(MEA)。根据业务流对应的无线测量信息和空口调度信息,结合移动边缘应用业务流的不同服务等级的预配置信息,从而给出业务流服务等级修改指导建议,并通过订阅的无线网络能力API通知给该移动边缘应用。文章重点研究5G无线能力开放系统架构、无线能力开放策略以及无线能力开放关键系统流程。

Mobile edge computing(MEC)plays an important role in 5G mobile communication network.It is built on the 5G access network side and close to mobile terminal users,which can effectively solve the demand of 5G network for high bandwidth and low delay.Mobile edge computing(MEC)obtains the wireless measurement information and air interface scheduling information of the base station,processes the strategy,and opens it to the mobile edge application(MEA)in the form of wireless network capability APIs.According to the wireless measurement information and air interface scheduling information corresponding to the business flow,combined with the preconfigured information of different service levels of the mobile edge application business flow,the guidance suggestions for modifying the service level of the business flow are given,and the mobile edge application is notified through the subscribed wireless network capability API.This paper focuses on 5G wireless capability open system architecture,wireless capability open strategy and key system processes of wireless capability open.
