Communication World Network News （CWW） Recently, China Telecom Hunan Company (hereinafter referred to as "Hunan Telecom") and ZTE completed the commercial verification of 5G-A "intelligent dual domain collaboration" innovation scheme in Changsha. Through the intelligent collaboration capability of frequency domain and airspace, it has solved the problems such as the decline of network overlapping domain performance and the imbalance of inter cell services under the traditional interoperability scheme, and effectively improved the user's business experience, It further promoted the efficiency of 5G network resources and the secondary growth of traffic. The deployment and performance verification of the actual scenario show that the intelligent dual domain collaboration scheme breaks through the boundary effect of the cell, significantly enhances the user experience, and further promotes the realization of seamless perception imagination.
After years of development, Hunan Telecom's 5G network has established a high-quality 5G network with multi band integration, including 3.5G, 2.1G and 800M. In different scenarios, the deployed 5G networks have different performance and networking methods in terms of frequency band, coverage, capacity, etc. In view of these complex networking situations, Hunan Telecom and ZTE launched the innovative scheme of "intelligent dual domain collaboration", which aims to achieve the effect of "good 5G signal and excellent experience" through intelligent technology and 5G-A cross station 3CC and other new features, that is, no matter what frequency bands are deployed in the 5G network, it can provide users with the best carrier or carrier combination service quality, This will improve the user experience and further stimulate network traffic.
At the same time, Hunan Telecom has closely linked this innovative scheme with the "signal upgrading" action of the Ministry of Industry and Information Technology, and actively expanded the breadth and depth of 5G network coverage in universities, supermarkets, residential areas, etc., so that the majority of 5G users can quickly experience more high-quality, efficient and intelligent 5G-A services. "Intelligent dual domain collaboration" has achieved remarkable results in multi scene commercial verification in Changsha. At Changsha University of Technology, the downlink user experience has more than doubled; In Nanhu Building, the average user experience at the edge of the community has increased by more than 23%; In residential areas, the uplink experience of users in residential buildings has increased by more than 36%. From the application effect of multiple scenarios, the overall network traffic also stimulates more than 9%, which fully reflects the serialized linkage ability of "intelligent dual domain collaboration" to achieve "traffic upgrading" through "signal upgrading", driving "experience upgrading".
Hunan Telecom and ZTE jointly launched the country's first "intelligent dual domain collaboration" technology, which demonstrated the consistency of 5G technology with market demand in the development and evolution of technology, and achieved efficient control of operating costs and overall improvement of investment benefits of indoor distributed systems on the business side. Later, Hunan Telecom will continue to work with ZTE to explore 5G-A innovation plans and intelligent applications, inject surging innovation power into 5G networks, and create high-quality 5G-A commercial networks.
