开放5G网络架构与开源平台

[摘要] 提出一种开放网络研究框架，及其开放网络架构解决方案。认为5G的3种业务场景向3类关键技术指标的灵活映射需求，决定了基于公共资源池的网络切片化是必然之选，网络架构的开放性是保障敏捷切片所必须的，网络和技术指标的演进也决定了传统垂直封闭网络架构不可持续。在该开放研究框架中，各层、各域均给出了相应的技术模块，传统垂直封闭网络协议架构也分别进行了解耦和集中化重构。该方案尝试性地满足性能、效率和业务需求，并与开源协作开发模式结合。

[Abstract] This paper proposes an open framework and corresponding open network architecture. The flexible mapping from three kinds of application scenarios to three groups of key performance indicators (KPIs) determines that it is necessary to construct specific network slice from a common resource pool. The openness of network architecture is the base to guarantee the agile slicing. In addition, the evolution of network and KPIs need also change the style of conventional vertical close architecture. The proposed open architecture provides corresponding modules in each layer and domain, and redesigns the conventional architecture with decoupling and centralization. This solution tries to meet the needs of cellular performance, network efficiencies and application requirement, and combines with the open source cooperation practices.
