Abstract

The invention provides a virtualized base station and a virtualized base station uplink and downlink data transmission method, which relate to the technical field of communications. Wherein, a base station of the present invention includes: a physical layer running on a hardware accelerator; and, a data link layer and a network layer running on a general-purpose hardware platform; wherein, the data link layer and the network layer use the application container engine Docker accomplish. Such a base station uses a hardware accelerator to realize the functions of the physical layer of the base station, and uses a general processing server based on the Docker engine to realize the functions of the data link layer and the network layer of the base station. , which greatly improves the computing performance of the entire system and reduces the processing delay; on the other hand, the use of Docker's high resource utilization can further improve the system performance of the base station.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a virtualized base station and a method for transmitting uplink and downlink data of the virtualized base station. Background technique [0002] With the development of virtualization technology, network virtualization has gradually extended from traditional wired network to wireless network, and has become a research hotspot of 5G (5th-Generation, fifth-generation mobile communication technology). However, unlike the relatively stable characteristics of wired network resources, wireless resources will change dynamically with changes in time and space, which requires very high real-time processing of virtual machines. Therefore, for the particularity of wireless network resources, wired network virtualization technology Further enhancements are needed to accommodate wireless network resource virtualization. [0003] The virtualization technology used in the traditional IT ...
