Open5G :5G网络的开放生态
Executive Summary
Three key application scenarios in 5G break the boundaries of communication between human
beings in traditional mobile communications, forcing 5G to support communication of
human-to-machine, and machine-to-machine. However, various application scenarios and
requirements together with emergingly diversified standards and technologies call for an open 5G
(Open5G) network, which is featured with flexibility and customization. This white paper
investigates the concepts, challenges and opportunities of Open5G network. The main contributions
of this white paper is summarized as follows:
(1) Key concepts of Open5G: upon analyzing the technical requirements, the concept of open
networks is provided from three different open levels, namely, black-box, white-box and gray-box
networks. Specifically, black-box open networks provide third-party applications or developers with
supporting services and key network capabilities via open application programming interface (API).
White-box open networks refer to the fully open network, which includes open source software
developing and white-boxing hardware design. The gray-box network is an partial open network,
where telecom operators and the equipment manufacturers cooperatively design the customized
network devices. Then, the overall objectives of open network architecture are figured out. Driven by
developing requirements, open network architecture should decouple network capability providers
and solution providers, enabling the former to effectively design network architectures with finite
resources and reducin
