Efficient oneM2M protocol conversion platform based on NB-IoT access

The protocol is the foundation of IoT technology, which plays an important role in the IoT device interworking and interoperability. The 5G wireless communication system provides large-scale NB-IoT terminals access with F-RAN, and the vertical industry applications need support for the device management. As one of the most influential protocol in the IoT application, the oneM2M protocol not only has a complete architecture, but also has an interface with other IoT protocols. Therefore, to bridge the gap between the operator and industrial enterprises, the main contributions of this paper are as follows: Firstly, a general multi-protocol conversion method is proposed based on oneM2M platform where the protocol classification is used in different scenarios. Secondly, the F-RAN architecture of oneM2M platform is designed and implemented with NB-IoT device access. Thirdly, a multiplexing scheme to process the device information is proposed for interworking proxy entity (IPE), which improves the conversion efficiency for different protocols. Finally, the feasibility and efficiency of the scheme are verified.
