  • Research on technology of cross-domain collaboration based on MEC for Internet of Vehicles
  • LEI Kairu, YU Bingyan
  • Information and Communications Technology and Policy. 2024, 50(3): 18-26. DOI:10.12267/j.issn.2096-5931.2024.03.003
  • Abstract ( 68 ) HTML( 29 )   
  • The technology of cross-domain collaboration based on MEC for Internet of Vehicles (IoV) is the key research point in the integration scenario of MEC-based C-V2X systems. The scenarios mainly include security, efficiency, collaboration, video, and information services. Each scenario involves processes and context specification information in the cross-domain collaborative interaction. At present, the technology of cross-domain collaboration based on MEC for IoV is in the early stage of development internationally, and organizations such as ETSI and 5GAA have not established corresponding and relatively complete international standards. Based on the mainstream edge computing system architecture of IoV, this paper focuses on the research of cross-domain requirements, interaction migration process and context specification based on MEC for application layers of IoV scenarios.

  • As an emerging emerging industry in China, the biopharmaceutical industry is facing difficulties both internally and externally. Digital transformation has become a necessary path for overcoming adversities. However, the digital transformation of the biopharmaceutical industry is currently constrained by four major bottlenecks: insufficient data foundation, relatively lagging policy regulation, lack of targeted evaluation systems, and shortage of compound talents. The progress of transformation is relatively backward. It is recommended to accelerate the digital transformation of the biopharmaceutical industry by unifying data standards, establishing public data resource systems, innovating regulatory models, constructing transformation evaluation systems, and cultivating talent teams.
