Jiangsu Unicom in network operation ａnd maintenance to digital, intelligent transformation, ａnd HUAWEI in the direction of intelligent operation ａnd maintenance cooperation, through the IES (Infrastructure enabling system) intelligent scheduling solution to realize the unified alarm monitoring, diagnosis ａnd self-healing of multi vendor products in the wireless domain of the province, the success rate of fault diagnosis is 90+%, greatly raised. Increase the efficiency of operation ａnd maintenance. Based on a profound understanding of business, Jiangsu Unicom, through a large number of operation ａnd maintenance data analysis, divided the project goals in a professional ａnd stage stage, ａnd jointly promoted the successful deployment of the IES intelligent scheduling solution with HUAWEI. HUAWEI has the operation ａnd maintenance experience of the global 1500+ network ａnd the perfect network operation ａnd maintenance fault tree model. The intelligent IES scheduling solution can make use of the model to analyze ａnd delimit the alarm of multi vendor products in the fields of wireless ａnd IPRAN transmission, ａnd realize the root cause analysis ａnd automatic healing. With the development of technology ａnd business, the network becomes more complex ａnd the demand of digital operation is becoming more ａnd more urgent. The successful practice of HUAWEI ａnd Jiangsu Unicom IES intelligent scheduling platform provides valuable experience for the transformation of industry ａnd maintenance. In the future, it will continue to enrich the application scene, help the operators to further improve the efficiency of operation ａnd maintenance, guarantee the efficiency of operation ａnd maintenance. The network is stable. On the morning of July 23rd, Beijing time (Jiang Junmu), in response to some American congressmen＇s criticism of HUAWEI＇s cooperation with the University, Xu Zhijun, chairman of HUAWEI, refuted in the financial times, calling it "ill-informed", ａnd focusing on the outside world. Information - HUAWEI supports US universities for basic research, which will benefit the public ａnd will not pose a threat to the United States. In this article, Xu stressed the importance of academic freedom ａnd discussed the key role of cooperation between universities ａnd enterprises for the progress of science ａnd technology, ａnd indicated that HUAWEI did not expect to obtain direct commercial returns when providing support, ａnd the research results were published in the form of professors, doctorates ａnd graduate students. He pointed out in particular that it is an arduous ａnd long process for any basic research project to benefit the society. It requires a close cooperation between universities ａnd enterprises, which requires a long ａnd hard struggle of scientists ａnd engineers, ａnd their efforts ａnd contributions should be respected rather than accusations. The full text is as follows: Not long ago, several U.S. congressmen severely criticized HUAWEI ａnd asked the Secretary of education to investigate whether HUAWEI＇s basic scientific research partnership with American universities would pose a threat to the security of the United States. I think these behaviors show their ignorance of science. In recent interviews with the media, I mentioned that these criticisms were "ignorant". I don＇t want to have a personal attack. On the contrary, I just want to emphasize the importance of academic freedom. Academic freedom is the basic attribute of modern universities, the cornerstone of all scientific ａnd technological progress, ａnd helps to train the next generation of scientific research personnel. Academic freedom is the cornerstone of higher education. It is because American universities can maintain academic freedom ａnd are not disturbed by political ａnd external factors, so that the best talents in the world have been studied ａnd studied in the United States, ａnd the status of the global technology leaders in the United States has been achieved. I am a doctor of Engineering in basic research. According to the National Science Foundation (National Science Foundation), "basic research" refers to "activities committed to acquiring new knowledge or ideas, but not considering specific processes or product applications." The R & D activities of enterprises mainly focus on commercial applications, while universities are concerned about applications such as mathematics, algorithms, materials science ａnd so on, which are unlikely to generate revenue. Even if a research project will eventually yield a return, it may take several decades from theoretical research to commercialization. University ａnd enterprise cooperation can effectively shorten the process. Knowledge ａnd resource exchange among enterprises, academia ａnd research institutions (also known as "knowledge transfer") have become the key driving force for scientific ａnd technological progress. However, over the past ten years, the federal government＇s funding for university research projects has continued to decline, ａnd now it accounts for less than 50% of the total university research funding. Most of the rest comes from sponsorship from companies such as HUAWEI. HUAWEI＇s research funding to American universities is relatively limited, which was about $10 million last year. But the support we provide is exactly what the university needs, including funding, venues ａnd laboratory equipment. At the same time, we have created abundant training ａnd practice opportunities for postgraduates ａnd university students. When providing these support, we do not expect to get direct business returns. HUAWEI supports American universities for basic research, which will benefit the public ａnd will not pose a threat to the United States, as critics say. Our research results are published publicly in the form of papers written by professors, doctorates ａnd postgraduates. In 2017, HUAWEI invested 13 billion 800 million US dollars in R & D field. Over the past ten years, HUAWEI has invested more than $60 billion in global research ａnd development. HUAWEI has been authorized by nearly 80 thousand patents around the world, including nearly ten thousand patents authorized in the United States, ａnd many of the basic patents in the telecommunications industry, which is also a contribution to the development of the digital economy. It is an arduous ａnd long process for any basic research project to benefit the society. It requires a close cooperation between universities ａnd enterprises, which requires a long ａnd hard struggle of scientists ａnd engineers, ａnd their efforts ａnd contributions should be respected.
