After a four-year absence, the 2024 Zhangjiajie Lantern Festival has returned with the theme of "Lantern Festival Wonderful Meeting, National Tide Carnival", attracting many citizens and tourists to watch. In order to ensure the smooth communication at the event site, Zhangjiajie Mobile went all out to carry out this communication guarantee work with high standards, strict requirements and strong measures.
Carefully planned to ensure that communication is foolproofAfter receiving the support task, Zhangjiajie Mobile attached great importance to it and set up a 63-member special working group for emergency support for the Lantern Festival, which organized multiple rounds of on-site net testing to collect data from January 12, and conducted in-depth surveys on the event site to sort out the on-site network structure and main coverage. Combined with the security needs, a detailed communication support plan was formulated for the insufficient capacity and possible congestion in Dayong Ancient City, Dayong Fucheng, Yanhe Road, People's Square and other areas, and the capacity balance and expansion adjustment were scientifically carried out.
In order to meet the rapidly growing business volume needs of densely populated areas during the event, so that the majority of citizens and tourists can enjoy checking in and taking pictures while visiting the park, and enjoy high-quality and high-speed network communication services, Zhangjiajie Mobile has expanded the capacity of more than 60 communities around the surrounding sites for large traffic and high-traffic scenarios in the core area, and added 16 temporary base stations for the first gathering area, coordinated 3 large-scale emergency communication vehicles, added 67 new communities, and increased the network carrying capacity in the region by 227% to ensure customer perception.
Apply new technologies and build a high-quality network with high standardsThe Lantern Festival Dragon and Lion Championship was held in the ** Sports Center, and Zhangjiajie Mobile and ZTE took the lead in opening the 3CC test station on the spot, completing the 5G-A three-carrier aggregation pilot, and the measured downlink rate reached a theoretical peak of 425Gbps compared to 2The 6G single-carrier rate is increased by 25 times, providing users with the ultimate mobile network experience.
It is reported that 5G-A three-carrier aggregation is referred to as 3CC, which is one of the key features of 5G-A6g (100+60m) and 4The 9G (100M) frequency band three-carrier networking achieves 260M usable ultra-large bandwidth, and is deeply integrated based on the characteristics of different frequency bands, further increasing the network thickness, expanding the coverage depth, and improving the ultimate performance.
Respond to challenges and demonstrate your expertiseIn order to cope with the communication peak that may occur on the day of the Lantern Festival, Zhangjiajie Mobile conducted a load assessment in advance and adopted 26g+4.9G+700M+4G collaborative networking, and complete large-capacity and large-capacity traffic deployment for guaranteed cells such as AMBR rate limiting, uplink power control, fast AMC in the access phase, and capacity stalls based on PRB utilization. During the event, Zhangjiajie Mobile dispatched a total of 61 support personnel and 37 support vehicles, and the wireless connection rate in the guarantee area was 99More than 3%, the drop rate is 08% or less, 4 The total number of 5G active users reached 1290,000 people, and the 4G perception rate reached 1438mbps，5g 2.6G perception rate 7665Mbps, 5G 700M, sensing rate 3252mbps, in the densely populated Dayong Ancient City, Huilong Road, Nanzheng Street, Jiefang Road and other performance venues, on-site test calls, Internet access, WeChat, Douyin and other services can be used stably and smoothly.
Construction, maintenance, optimization and other comprehensive coordination to ensure that the work and the process of activities are closely connected. On the day of the Lantern Festival, the Zhangjiajie mobile technology team stuck to their posts, on-site support personnel carried out on-site network perception monitoring of the event, and background personnel monitored the status of the base station in real time and adjusted the capacity warning community in time. During this guarantee activity, the network operation remained stable during the whole period, and there was no large-scale call congestion and important customer complaints, achieving the guarantee goal of "zero major network failures, zero important customer complaints, and zero major network security incidents".
