Beijing Subway Line Line 6 lost communication signal operators said it was irrelevant

Sina Science and technology news November 22, in response to the recent Beijing subway line Line 6 station in the telecommunications, Unicom mobile phone signal failure, Beijing Telecom and Beijing Unicom have said it has nothing to do with them, because the subway line Line 6 communication equipment is built and maintained by the MTRC itself, the actual contractor is the Tong Group Shanghai Company. Communication signal fault reason and Unicom Telecom has nothing to do recently, there are media reports, found in Beijing subway line Line 6, Mobile has a stable 2G signal, Unicom 2G network slightly weak, but still can call, and telecommunications CDMA mobile phone is not any signal. After the Beijing Telecom 10000 Customer Service hotline consultation, customer service staff said the situation is true, but Beijing Metro line Line 6 communication equipment is not Beijing telecom construction, can only wait for the subway company to repair. Beijing Unicom Customer Service staff also said the Beijing subway line Line 6 communication equipment and Beijing Unicom has nothing to do. Metro communication signals are the responsibility of the MTRC. The matter has again aroused people's concern about the traffic management and construction maintenance mode in the subway. Previously, the telecommunications operators and the MTRC has repeatedly "admission fee" controversy, so that the subway communication signal coverage, especially the construction of new Subway communications network has become a "long-standing." Later, under the coordination of the Beijing Municipal government, the Metro company and the three telecommunications operators agreed on the principle of the construction and operation of metro Communication network. Under the agreement, telecom operators will pay the MTRC a certain amount of fees each year in accordance with the number of subway base stations, that is, admission fees. In order to avoid duplication of construction and unnecessary rework after the building, the Beijing municipal government requested Beijing to follow up the new subway to complete the communication network, radio and television network and the communication coverage. On the basis of this agreement, three operators formed a new mode of joint-construction and sharing. If the communications network is built by the MTRC, whether repo or commissioned, three telecom operators will jointly negotiate with the MTRC. As a result, 2012, the subway communication signal began to fully unobstructed, in September 2012, Beijing Unicom announced that the Beijing subway Line 1, Line 2, all the platform has completed the Unicom 3G signal coverage, and 1, Line 2 Metro tunnel Unicom 3G coverage will be completed at the end of the year. China Telecom's Beijing company said at the time that Beijing Telecom's 2G network signal had covered the platforms and tunnels currently operating 11 subway lines, the 3G signal is also covered by 10 metro lines and will be implemented as soon as possible 3G coverage of all the lines that have been opened, including 10 metro lines (1th, 2nd, 5th, 8th, 9th, 10th , 13th, 15th, Daxing, also Zhuang line of the platform, the tunnel has completed the 3G signal coverage. Beijing Metro Line Line 6 is constructed by Tong No. Shanghai Company However, the technology of metro communication is far more complicated than terrestrial communication, therefore, it is the key to build and maintain a good communication network, and the MTRC is also entrusted with the construction and maintenance of a third party's professional technology company. For example, the Beijing metro line Line 9 is a successful communication and signal system design by China Tong Group, while the Beijing metro line Line 6 Communication System Project is responsible for the whole implementation by the new Hisense Technology company, Shanghai company. But, specifically to the Beijing Metro line Line 6 is what caused the communication signal fault and who is responsible for, it is not clear. (Cang)
