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 ...
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。 六、C-RAN和Mass MIMO5G RAN进步带来了C-RAN(集中式...
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...
Network Slicing is considered as one of the key feature by 3GPP in 5G. A network slice can be looked as a logical end-to-end network
network device, wherein the RAN control entity is coupled to a baseband unit (BBU) and remote radio head (RRH), and circuitry to partition a physical RAN infrastructure or C-RAN into one or more network slices, and partition the BBU and/or RRH according to a deployment scenario of the ...
With Open RAN, Massive MIMO, network slicing, and 5G vRAN architecture adding complexity and diversity to the RAN landscape, the test tools and processes of the past no longer suffice. Flexible RAN enabling enhanced mobile broadband, (eMBB), ultra-reliable low latency communications (URLLC), and...
5G has been widely deployed and it now presents tremendous potential for service providers to monetize new services for consumers and enterprises. Network slicing is a key enabler for unlocking opportunities through service differentiation and guaranteed performance. Using an end-to-end approach, Ericsson...
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. ...
