In the usual NFV infrastructure layer embodiments, hardware devices usually use kernel-level virtualization technology ( Kernel-based Virtual Machine (KVM) is virtualized into multiple virtual machines, and multiple virtual resources are formed into a cloud pool through Openstack. The virtual network layer can correspond to each telecommunication service network and each virtual network in the virtual network layer. The resources required by the virtualized network function (VNF) network element need to be decomposed into virtual computing, storage, and switching resources. The service network management of the VNF can use Network Element (NE)-Element Management System (EMS). ) - Network Management System (NMS) system. The VNF of the base station in this solution is simply referred to as vBS; MANO completes the management of the hardware and software resources of the infrastructure layer, the life cycle management and orchestration of the VNFs.
基站无线接入网(Radio Access Network,RAN)可以由天线、射频拉远单元(Radio Remote Unit,RRU)和基带单元(Baseband Unit,BBU)组成。RAN的NFV化实现,涉及到这3个功能实体虚拟化和云化改造。但是这3个功能实体的虚拟化和云化存在困难。The base station radio access network (RAN) may be composed of an antenna, a radio remote unit (RRU), and a baseband unit (BBU). NF's NFV implementation involves the virtualization and cloud transformation of these three functional entities. However, the virtualization and cloudization of these three functional entities are difficult.
天线是纯物理设备,无法进行虚拟化改造,同时天线是解决覆盖问题的,和位置强相关,如何成云是一个需要解决的问题。The antenna is a pure physical device, which cannot be virtualized. At the same time, the antenna solves the coverage problem and is closely related to the location. How to form a cloud is a problem that needs to be solved.
RRU可以由射频硬件和射频算法处理芯片组成,其中射频硬件属于专用硬件,同时射频算法处理芯片由于对延时、功耗效能要求很高,一般使用专用数字信号处理(Digital Signal Processing,DSP)芯片。因此RRU不能采用传统的虚拟化技术,RRU如何虚拟化是一个需要解决的问题;同时RRU受限于频段和 制式等信息,而且和天线是强绑定的关系,因此RRU如何形成虚拟资源云池也是一个需要解决的问题;The RRU can be composed of RF hardware and RF algorithm processing chips. The RF hardware belongs to dedicated hardware. At the same time, the RF algorithm processing chip generally uses dedicated Digital Signal Processing (DSP) chips due to high latency and power consumption requirements. . Therefore, RRU cannot adopt traditional virtualization technology. How to virtualize RRU is a problem to be solved; at the same time, RRU is limited by frequency band and Information such as the standard, and the strong binding relationship with the antenna, so how to form a virtual resource cloud pool is also a problem to be solved;
BBU部分可以提供L1、L2和L3的处理,L1和L2-介质访问控制(Medium Access Control,MAC)通常由基带处理器(Baseband Processor,BP)板卡提供,并且对并发性、时延、吞吐量和处理效能要求很高,相关技术中的BP板卡以及中长期内都采用的是DSP芯片处理,不能采用传统虚拟化技术(与以太网L1&L2 PHY/MAC类似,需要由专用以太网硬件实现)。而L3部分对时延要求不高,可以在X86/ARM(Advanced RISC Machines)通用芯片上的虚机运行。The BBU part can provide L1, L2, and L3 processing. The L1 and L2-Medium Access Control (MAC) are usually provided by the Baseband Processor (BP) board, and the concurrency, delay, and throughput are provided. The quantity and processing efficiency are very high. The BP board in the related technology and the DSP chip processing in the medium and long term can not adopt the traditional virtualization technology (similar to the Ethernet L1&L2 PHY/MAC, which needs to be implemented by dedicated Ethernet hardware. ). The L3 part does not require a high latency and can be run on a virtual machine on the X86/ARM (Advanced RISC Machines) general-purpose chip.
从上面的分析可以得出,vBS依赖的专用硬件资源在相关技术中的虚拟机技术(比如KVM/VMWare等)下不支持虚拟化的问题。From the above analysis, it can be concluded that the dedicated hardware resources that the vBS relies on do not support the virtualization problem under the virtual machine technology (such as KVM/VMWare, etc.) in the related art.
