In the past weekend, I believe that many people's circle of friends has been screened by Polar code. Because on the just-concluded 3GPP RAN1 #87, the Polar code led by Huawei and the Chinese Legion was officially adopted as the control channel coding scheme of the 5G eMBB scenario, which laid a good foundation for the subsequent standard formulation and industrial layout. If you think that the Polar code is the highest honor of the Chinese Legion at the 3GPP Joint Conference, it may be wrong. At the 3GPP Joint Conference in the middle of this month, the performance of the Chinese Legion was amazing, and even Polar code was just an appetizer. Because at the just-concluded 3GPP SA2#118 meeting, after a heated discussion, China Mobile successfully led the 5G system design and was the only speaker of the project. Dr. Sun Wei from the China Mobile Research Institute of Network Technology served as the rapporteur. . This project is R15 "5G System Architecture", referred to as 5GS, is the first technical standard of the whole 5G design, and is also the basic standard for 5G system-wide design, marking the entry of the 5G standard into the substantive phase. It is reported that the 5GS project will formulate two basic standards of "5G system overall structure and function" and "5G system basic process", which is expected to be completed in December 2017. In late October last year, the 5G network architecture discussion officially kicked off in 3GPP. After intense discussions among companies in the global communications field, the “next generation system architecture design†led by China Mobile was applauded! In the promotion of this project, the 5G core network team from China Mobile Research Institute has made great efforts. In the previous study, which lasted more than a year, China Mobile took the lead in the next-generation system architecture research project “NextGen†(TR 23.799). Driven by the concept of innovation, China Mobile has pushed 5G into a network of “software, service, and agilityâ€, but it has been challenged by conservative forces in the new architecture design. After all, the standard dispute involves huge commercial interests. The standard dispute has long surpassed the technical boundary, but the contest between comprehensive strength and discourse power. Through unremitting efforts, under the active promotion of operators such as China Mobile, AT&T, and Germany, China's IMT-2020 Promotion Group and Huawei, the company has formed an important consensus on the overall architecture of the 5G system: the "service-based" modular design will become The main features of the 5G system architecture. Compared with the traditional "request-response" based network process, the design concept based on "microservice" is expected to bring disruptive design to the 5G system architecture. Bao Jianfeng smashed out, plum blossoms came from bitter cold. This is not only the glory moment of the China Mobile Research and Development Team, but also the glory moment of China Mobile. It is also the glory moment of the entire Chinese army. On the other hand, we must realize that the unification of the 5G standard requires a joint effort and a game of chess around the world. In the context of global collaboration, global collaboration is essential. In fact, we can see this trend from the list of SupporTIng Companies. China Telecom, represented by China Mobile and Huawei, is joining the global industry governance in a more open and inclusive manner. Metal boxed access control Power Supply
