1. In formulating technical standards, China Telecom actively participates in the formulation of international standards. Up to now, * * * has led 33 international standardization projects and work, submitted 659 manuscripts of 5G international standards, and applied for 224 5G patents.
2. In the research and development of technical solutions, combined with the characteristics of China telecom network, innovative solutions are put forward around the * * * sharing platform for cloud and network convergence, edge computing supporting fixed-mobile convergence, 4G/5G collaboration based on service awareness, and high-speed WDM-PON bearer for 5G forward transmission, which has been recognized and supported by the industry; At present, China Telecom has taken the lead in realizing 4G/5G interworking based on independent networking (SA) and interworking between different vendors of 5G core network based on SA, which has effectively promoted the maturity of 5G SA equipment networking capability.
3. In terms of 5G service and mode innovation, combined with the ultra-high bandwidth and low delay characteristics of 5G, we carried out demonstrations of 5G+ Tianyi HD and 5G+VR live broadcast applications, and explored innovative applications such as 5G+ unmanned buses and 5G boutique loop lines in Shenzhen and Chengdu. CCTV successfully completed the Spring Festival Evening live broadcast based on 5G; Combined with 5G super-large connection, it will serve the construction of smart cities, promote smart logistics, and promote the smart water control of Xiong 'an Baiyangdian.
In addition, China Telecom took the lead in formulating the international standard of ITU's 5G business model. Focusing on this standard, the application scenarios and business models of 5G network slicing are discussed. Combine the technical features of 5G with our new networks and capabilities such as cloud computing and Internet of Things to achieve cross-border integration with vertical industries, and actively explore 5G-related application cases and business models in vertical industries such as power, logistics, banking, automobiles, media, medical care and smart cities.
4. Leading 5G with operational requirements. In June, 2065438+2008, China Telecom published the White Paper on 5G Technology, which was the first time in the industry to release and comprehensively expound the viewpoint and overall strategy of 5G technology, indicating the strategic choice of China Telecom, which has great guidance and guiding value for industrial ecological development.
