Mobile network vendor ZTE on Monday said it has completed 4G LTE network stress test for China Telecom in Shanghai — offering better performance.
China Telecom organized the test in Shanghai and ZTE network delivered exceptional performance, where one single CS accessed a maximum of 450 subscribers simultaneously for the first time. The access success rate reached 100 percent and the CPU load was lower than 30 percent.
The 450 subscribers accessed the video services at the same time, which made the cell’s throughput exceed 100Mbps, but the CPU load was still lower than 9 percent, said ZTE.
In addition, ZTE that competes with Huawei, Ericsson, Nokia Networks, Alcatel-Lucent, etc. designed the test case for signaling storm. The 450 subscribers executed paging and activating repeatedly. In this case, system KPIs were fully normal, and the CPU utilization was about 36 percent. ZTE claims that its 4G network handled the burst of large traffic, proving that the system can handle issues resulting from the signaling storm.
The Chinese telecom equipment vendor also shared its successful tests with other mobile operators in the world.
During Hong Kong Sevens in 2013, CSL’s LTE network built by ZTE provided over 40,000 subscribers with premium quality services.
In Admiralty Station, a busy subway station in Asia, 4G sites deployed by ZTE satisfied the most stringent requirements, even when the single cell’s RRC connections reach 800, the CPU load still keeps at a lower level, ensuring the stable performance of system.
Earlier, Hong Kong CSL’s network performance was ranked No. 1 in the third party comprehensive evaluation.
Austria H3G’s wireless KPIs topped the third party test.
