Zheng Sigautie Mobile phone call is not smooth at the end of March will be the basic solution

Xinhua Zhengzhou February 9 (reporter Peng) speed of up to 350 kilometers per hour high-speed railway opened, to mobile communications brought new challenges, many passengers reflect on the high-speed rail when the mobile phone call is not smooth.　　Reporter to understand that the relevant units are stepping up the network construction and optimization, the end of March this year, Zheng Sigautie mobile phone calls problems will be basically resolved. Wuhan, Zheng Sigautie opened after the operation, passengers reflected in high-speed trains in the mobile phone call is not smooth phenomenon is more common.　　During the Zheng Sigautie trial run and after the opening, the reporter found that on the high-speed rail calls often appear on the signal is not smooth, when the call breaks, and so on, and so on, only to send and receive short message to maintain normal, this problem does bring inconvenience to some passengers. What is the reason why the high iron mobile phone call is not smooth? Zhangchungui, general manager of China Mobile Henan Branch Engineering Construction Center, said because the high-speed train speed is very fast, in a very short period of time the train will pass through several base stations, which means that the mobile phone signal will be in the rapid switching between several base stations, it is difficult to ensure the normal call needs, resulting in a drop line. In addition, the high speed train compartment tightness is also getting better, resulting in more signal decay, resulting in poor call quality.　　In addition, high-speed rail tunnels along the road is also caused by poor communication. High-speed railways are a new thing, as is the case with communications equipment and technical guarantees.　　Reporter learned that from 2009 onwards, China Mobile Henan Branch investment of 120 million yuan, began in the Zheng Sigautie Henan section of more than 300 kilometers along the special network construction, Shaanxi province by the Shaanxi Branch for the synchronous construction, the current cable laying has been basically completed. Zhangchungui said, line laying and equipment installation, and so on, will hurry to debug, and strive to the end of March to basically solve the problem of Zheng Sigautie call, complete the special network coverage.　　He added that this phase of the project is mainly to solve the 2G call problem, on this basis to improve the resolution of the 3G call problem. According to Henan Unicom Company Responsible person, the current Unicom company along the Zheng Sigautie of the network cover construction is also intensified, and synchronous resolution of the 2G and 3G call issues, in the end of March this year to complete the construction and commissioning. By then, Zheng Sigautie mobile phone calls will be basically resolved.
