Background of achievements
5G network intelligence is one of AsiaInfo’s strategic development goals of “One Consolidation, Three Developments”. AsiaInfo has started in the 4G era to conduct targeted technical pre-research and talent reserve in advance for the field of 5G network and data intelligence, and created a full-stack product system in the field of 5G network intelligence which has been fully implemented in the commercial use of China’s 5G in last two years. At the same time, AsiaInfo has also become one of the main contributors to international standard proposals in the field of network intelligence in international standard organizations such as ITU, 3GPP, and ETSI.
In August 2021, the Chinese Association for Artificial Intelligence organized a meeting in Beijing to appraise the technological achievements of the “R&D of 5G network intelligent system and industrial large-scale application” jointly completed by AsiaInfo and Tsinghua University.
The Achievement Appraisal Committee is led by 4 academicians. Among them, Academician Sun Ninghui (Academician of Chinese Academy of Engineering and Academic Director of the Institute of Computing Technology of Chinese Academy of Sciences) serves as the Chairman of the Committee, Academician Zhang Yaqin (Academician of American Academy of Arts and Sciences, Academician of the Australian Academy of Engineering and Dean of Institute for AI Industry Research and Chair Professor of Intelligence Science of Tsinghua University), Academician Yao Yudong (Academician of Canadian Academy of Engineering, Tenured Professor of Stevens Institute of Technology), Academician Yang Qiang (Academician of Canadian Academy of Engineering, Chief AI Officer of WeBank, Director of Computer Department of HKUST), Professor Chen Shanzhi (Member of the Standing Committee of Party Committee and Deputy General Manager of CICT), Professor Hu Qinghua (Dean of the School of Artificial Intelligence, Tianjin University), Professor Cao Jiguang (Deputy Director of the Institute of Technology and Standards of CAICT), Researcher Ge Jingguo from Institute of Information Engineering of CAS, and Researcher Chen Shudong from Institute of Microelectronics of CAS serve as committee members.
