3GPP proposes a variety of 5G and 4G interoperability solutions, including 5G SA networking and NSA networking. The SA scheme is 5G NR direct access to 5GC, the control signaling is completely independent of the 4G network, and the 5G network and the 4G network are coordinated through the core network interoperation; the NSA anchors the 5G control signaling to the 4G base station through 4G. The base station accesses the EPC or 5GC.

Xu Zhijun, vice chairman of Huawei, said at the meeting that there are two major needs in the Chinese market on 5G: eMBB (enhanced mobile broadband) and industry digitalization. “Industry digitization requires 5G SA”. Xu Zhijun emphasized that only the networking mode of SA can realize the three application scenarios of eMBB, mMTC and uRLLC, and finally achieve high rate (10Gbps), low latency (1ms) and large connection.

In fact, with the SA solution, the 5G network can support new features such as network slicing and MEC, which can better support vertical industry applications such as low latency and various industrial Internet.

At the same time, the SA solution can avoid frequent network transformation problems under the NSA scheme, and at the same time, the service capability is stronger and the terminal cost is low.

In 2018, China Telecom released the “China Telecom 5G Technology White Paper”, proposing the establishment of a SA-based, SA/NSA hybrid network cross-provincial cross-domain scale trial network.

Ke Ruiwen, chairman of China Telecom, announced at the meeting that China Telecom has now built a cross-provincial cross-scale scale trial network of SA-based and SA/NSA hybrid networks, which will be launched in 17 cities including Beijing, Shanghai, Guangzhou, and Shenzhen. 5G innovation demonstration pilot.

In terms of 5G core capabilities, China Telecom also vigorously carried out technological innovation. It is the first to propose three clouds (access cloud, control cloud, and forwarding cloud) 5G architecture, which has become the basic solution of China’s 5G network architecture.

This core concept has also been integrated into 3GPP international standards; it has completed the industry’s first 5G SA end-to-end. The network’s network slicing laboratory verified and verified the multi-slice scenario for the first time in the Guangdong trial network; it has successfully completed the independent research and development of the MEC platform and can provide network service integration capabilities and third-party service management capabilities.

Demonstrate 5G application scenarios for many industry applications

The construction of 5G networks requires clear industry application scenarios.

For consumers, 5G smart terminals are direct access methods using 5G networks. This time, there are also many terminal upstream and downstream manufacturers participating in China Telecom’s 5G Innovation Cooperation Conference.

Exhibitors include manufacturers shift away Wingtech, Shenzhen G & Wireless Co., Ltd., as well as Huawei, ZTE, Xiaomi, OPPO, Vivo, Nokia, Samsung, HTC and other live demonstration of each model 5G modules, as well as smartphones Intelligent devices such as smart speakers and VR glasses have a total of 19 models.

Sina Technology experienced the use of a smartphone to connect to a 5G network. From the perspective of watching online video scenes, it can realize random drag and play without buffering.

At the same time, China Telecom also displays 5G cloud games, cloud VR and other applications. Cloud games do not need to download and install packages, which reduces the threshold for the use of large games.

Cloud VR implements computing on the cloud and rendering on the cloud, greatly reducing latency and better VR experience. “5G is not just 2C, it is 2B.” Ke Ruiwen said when talking about the 5G application scenario. These 2B customers include both corporate and government agencies.

For 2B customers, China Telecom has released many 5G innovative applications. It is reported that China Telecom’s 5G joint trial customers have exceeded 200, and 5G innovative application development in the top 10 vertical industries such as transportation, medical care, media, tourism, police, ecology, party building, car networking, education, and manufacturing.

Take smart police as an example, through the integration of 5G network, smart devices, AI, cloud computing, 3D big data visualization, and other technologies, to achieve high-altitude patrols, motorcycle patrols, and cloud linkage command applications, provide comprehensive wisdom Police solution.

China Telecom and Shenzhen Public Security jointly built the world’s first 3G+X-based stereo patrol and intelligent police, using cloud computing, big data, Internet of Things, artificial intelligence, and police platforms to enhance the efficiency of mobile law enforcement.

Another example is 5G+ intelligent transportation. Based on 5G high bandwidth and low latency, it can support high-definition video backhaul, 4K video remote interaction, remote mobile air traffic command, and cloud network convergence to solve many existing traffic problems. China Telecom and Chengdu have created a three-way traffic control and Chengdu smart bus landing scene.

These 5G applications will undoubtedly bring tremendous growth momentum to the industry. Xu Zhijun believes that for smart healthcare, smart industry, and other industries, 5G will increase its production efficiency by 10 times.
