China Mobile unveils 6G architecture with a digital twin network (DTN) concept

China Mobile, the world’s largest telecom carrier by mobile subscribers, unveiled its overall architecture design for 6G in a white paper on Tuesday, as it steps up its push into research and development of the next-generation wireless technology. China Mobile’s 6G network architecture is claimed to be the first systematic 6G architecture design in the telecom industry, according to the company.  However, state owned China Unicom published a similar white paper for 6G tech in April 2021.

China Mobile’s 6G architecture is based on both a systems design and networking design of architecture implementation.  The “White Paper” proposes a three-body, four-layer and five-sided 6G overall architecture design, which is the industry’s first systematic 6G network architecture design. Among them, the “three bodies” are the network ontology, the management orchestration body, and the digital twin; the “four layers” are the resource and computing power layer, the routing and connection layer, the service-oriented function layer, and the open enabling layer, and the “five layers” are the control layer. face, user face, data face, intelligent face, security face. On this basis, the “White Paper” also proposes that a virtual twin should be created digitally to realize a digital twin network architecture with network closed-loop control and full life cycle management; so as to realize plug-and-play, flexible deployment and other characteristics of the network architecture. Distributed homemade network.

The 6G architecture creates a virtual twin through digital means to realize a digital twin network architecture (DTN) with network closed-loop control and full lifecycle management; The service defines the end-to-end system to realize the full service system architecture (HSBA); In the group network, the distributed autonomous network (Dan) with distributed, autonomous and self-contained features is implemented, which supports on-demand customization, plug and play and flexible deployment.

According to the latest data, the total number of China Mobile customers has reached 967 million, with a net increase of 202,000 this month and a cumulative net increase of 9.706 million this year. The cumulative number of China Mobile’s “5G package users” has reached 4.95 million.  Note that the “5G package” statistic counts those on 5G plans who have NOT yet upgraded to 5G service.  The three state owned operators reported a total of 899.3 million subs at end-May. They have added 241 million since the start of the year and at this rate will run down the 1 billion mark themselves by the middle of August. But the real number of 5G users is just over half that – 410 million, according to the MIIT. That’s up from 355 million in December and, taking into account the debut of the fourth operator, China Broadcast Network, as early as this month, China’s total should easily pass 460 million by the end of the year.
