摘　　要：5G系统的飞速发展支持许多车联网用例对服务质量(quality of service,Qo S)的苛刻要求。但网络和应用的适配仍然存在很多问题。网络信息开放是一种潜在的解决方案,旨在实现网络向应用程序实时提供蜂窝无线网络信息,从而帮助服务提供方实现更好的策略控制并改善用户体验。提出一种基于网络信息开放的服务质量预测(predictive QoS,PQo S)方法,通过提前预测即将发生的网络变化来支持应用做出提前响应,提高用户的体验质量(qualityofexperience,Qo E)。介绍了网络信息开放及PQo S的背景,并介绍了PQo S的国内外研究、标准及落地现状;提出一种远程遥控驾驶(tele-operateddriving,To D)场景下基于网络信息开放的Qo S预测方法;对实际测试的数据进行分析,评估验证了PQo S的可行性。结果表明,基于网络信息开放的Qo S预测技术能够良好地支持包括5G ToD在内的车联网应用,为5G系统在智慧交通行业的落地提供了参考。The rapid development of 5G systems supports the stringent quality of service(QoS)requirements for many Internet of vehicles(IoV)use cases.However,there are still many problems in the adaptation of networks and applications.Network information exposure is a potential solution that also enables the network to provide real-time cellular wireless network information to applications,thereby helping service providers achieve better policy control and achieve an expe-rience for users.A predictive QoS(PQoS)method based on network information exposure was proposed.Applications could respond in advance and improve users’quality of experience(QoE)by predicting upcoming network changes.Firstly,the background of network information exposure and PQoS was introduced,and the research,standards,and im-plementation status of PQoS both at home and abroad were introduced.Then,a QoS prediction method based on network information exposure in tele-operated driving(ToD)was proposed,and experiments were carried out through actual test data and the feasibility of PQoS was verified through the evaluation and analysis.The results show that the QoS prediction based on the network information exposure can well support the application of some IoV,including 5G remote driving,which provides a reference for implementing the 5G system in the smart transportation industry.
