Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for virtualizing base station hardware, and a base station.
Background
The ETSI (European Telecommunications Standards Institute) NFV (Network Function Virtualization) architecture model provides an architecture idea for Network Function Virtualization, and in the ETSI NFV classic architecture model, a system is divided into 3 blocks, i.e., infrastructure layer/virtual Network layer/MANO (Management & organization, Management organization domain). In a general NFV infrastructure layer embodiment, a hardware device is generally virtualized into a plurality of Virtual machines by using a KVM (Kernel-based Virtual Machine), and various Virtual resources are made into a cloud pool by using an Openstack; the virtual Network layer corresponds to each current telecommunication service Network, resources required by each VNF (virtual Network Element) Network Element in the virtual Network layer need to be decomposed into virtual calculation/storage/exchange resources, and the service Network Management of the VNF still adopts an NE (Network Element ) -EMS (Element Management System) -NMS (Network Management System) System, for simplification, the VNF of the base station is abbreviated as vBS in the present scheme; the MANO completes the management of software and hardware resources of an infrastructure layer and the life cycle management and arrangement of VNFs.
A base station RAN (Radio Access Network) generally includes an antenna, a Radio Remote Unit (RRU), and a Base Band Unit (BBU). The NFV implementation of RAN necessarily involves virtualization/clouding transformation of these 3 functional entities. But virtualization/clouding of these 3 functional entities each presents difficulties.
The antenna is a pure physical device, cannot be subjected to virtualization transformation, solves the coverage problem, is strongly related to the position, and is a problem to be solved by how to form a cloud;
the RRU is composed of a radio frequency hardware and a radio frequency algorithm processing chip: the rf hardware belongs to a dedicated hardware, and since the rf algorithm processing has high requirements on delay and power consumption, a dedicated DSP (Digital signal processing) chip is generally used. Therefore, the RRU cannot adopt the traditional virtualization technology, and how to virtualize the RRU is a problem to be solved; meanwhile, the RRU is limited by information of frequency bands \ systems and the like and is in a strong binding relationship with the antenna, so that the problem of how the RRU is clouded into a resource pool is also solved;
the BBU part mainly provides processing of L1& L2& L3, L1/L2-MAC is usually provided by BP board, which has high requirement on concurrency/delay/throughput/processing efficiency, and existing BP board and DSP chip processing are adopted in middle and long term, and conventional virtualization technology cannot be adopted (this is also easy to understand, and is implemented by dedicated ethernet hardware as compared with ethernet L1& L2 PHY/MAC). And the L3 part has low requirement on time delay and can run on a virtual machine on an X86/ARM general chip.
From the above analysis, it can be seen that vBS relies on dedicated hardware resources that do not support the problem of virtualization under existing virtual machine technologies (e.g., KVM/VMWare, etc.).
