摘　　要：面对多场景、差异化的5G业务,为了需满足不同应用场景在如时延、网速、安全性及网络覆盖率等方面的不同网络性能要求,网络切片技术作为5G中的一项关键技术,能为不同用户提供多样化的按需定制服务,针对这个问题,本文设计在Openstack平台上实现了基于OAI组网的5G网络切片的自动部署。实验表明,该方案提高了移动通信物理资源及网络资源的利用率,使得自动部署的实现使得切片的管理编排更加灵活方便。Faced with multi-scenario and differentiated 5G services,in order to meet the different network performance requirements of different application scenarios,such as delay,network speed,security and network coverage,network slicing technology,as a key tech nology in 5G,can provide various customized services on demand for different users.To solve this problem,this paper designs and im plements an OAI-based group on Openstack platform.Automatic deployment of 5G network slices.Experiments show that the scheme improves the utilization ratio of mobile communication physical resources and network resources,and makes the implementation of auto matic deployment more flexible and convenient for slice management.
