5G中无线网(RAN)是这样支持网络切片的! 一、网络切片(Networkslicing)是3GPP定义的”允许运营商提供具有客户特定功能的专用逻辑网络“,同时不会因此失去通用基础设施规模经济;也就是允许从网络资源提供抽象服务,满足具有不同要求的用例。其中: 每组用户服务(如语音)由移动网络运营商的一个网络切片提供;而一些终端(UE)...
network slicing两种架构 ran网络架构 目录 1. UE初始接入 2. gNB-CU内的移动性管理 3. 丢失PDU的集中重传机制 4. 多连接操作 5. F1启动和小区激活 6. RRC状态转换 7. RRC连接重建立 8. Multiple TNLAs for F1-C 1. UE初始接入 (1)流程图 (2)简要说明 ① UE向gNB-DU发送RRCSetupRequest消息。 ② ...
这是由于今天的CN已经高度虚拟化,CN的功能一般都运行在通用计算机上。 网络切片(network slicing) 网络切片是服务于特定业务或客户需求的一个逻辑网络。它是在基于服务的架构中选择必要功能配置组合在一起而构成的。如:可以构造一个网络切片来支持与LTE类似具有完全移动性的宽带应用,或者构造一个网络切片支持非移动但是...
TS 23.501 defines Network Function, Slice, and Slice Instance in terms of Network Slicing Network Function:A 3GPP adopted or 3GPP defined processing function in a network, which has defined functional behavior and 3GPP defined interfaces. (Note: A network function can be implemented either as a n...
The proposed RAN Network Slicing solution is shown to reliably sustain service guarantees of critical applications, while coexisting with non-critical services. Application-dependent, dynamic, inter-slice resource sharing enables an efficient use of available RAN spectrum. Finally, we demonstrate dynamic ...
五、切片与虚拟化5G RAN引入了网络切片(Network Slicing)的概念,允许在单个物理基础设施上创建多个虚拟网络(Virtual Networks)。网络切片可以定制网络资源以满足特定应用的需求,从而确保最佳性能和效率。此外,5G RAN带来的网络功能虚拟化允许更灵活和可扩展的部署。
Network slicing is considered to be a crucial feature of fifth generation cellular systems. By dividing the network infrastructure into multiple logical segments, network slicing can support parallel services with different requirements. While technology developments focus on slicing the core networks, there...
The 3GPP specifications recognized this requirement for next-generation mobile apps, and so they introduced network slicing, a virtualization primitive that allows an operator to run multiple differentiated virtual networks, called slices, layered on top of a single physical network. ...
从业务层需求看,5G引入切片(Slicing)技术。端到端网络切片(Network Slicing)基于统一的物理网络设施提供多个逻辑网络服务,以实现业务快速上线与灵活扩容,助力新业务拓展和垂直行业应用的引入。网络切片既能提供传统的MBB基础通信服务,也能满足垂直行业差异化的数据传输需求,同时也可以支撑差异化的网络应用相关服务。
