Both China Telecom and China Mobile have to develop satellite phones. The Ministry of Industry and Information Technology stipulates that Tiantong No. 1 must be registered in real names. Operator World Network exclusively learned that China Telecom and China Mobile signed a supplementary agreement for network interconnection of the Tiantong No. 1 satellite mobile communication system. It seems that these two major operators will work together to develop satellite mobile communications. It also raises questions, how is the development of satellite mobile communications now?It is reported that 29 provincial-level companies of China Telecom have completed the inter-network data production work, and there are still two provinces such as Shandong and Liaoning that have not completed the work. China Telecom requires relevant provincial companies to increase coordination efforts, complete the signing of provincial interconnection agreements and data production as soon as possible, and cooperate with satellite companies and the network transportation department of group companies to complete the Tiantong No. 1 inter-network dialing test work. At the same time, Operator World Network learned that Tiantong No. 1 is currently operated by China Telecom Group. China Telecom, as the only operator among my country's basic telecommunications operators that has a satellite mobile communication license, released the Tiantong-1 dedicated 1740 number segment for the commercial market for the first time on May 16, 2018. Data show that the Tiantong-101 satellite used in the Tiantong-1 satellite mobile communication system is my country's first mobile communication satellite. Its basic principle is to rely on the wide-area coverage capabilities of artificial satellites and provide communication services for a large geographical area through relay communication means. The biggest advantage of satellite communications is that there are no blind spots in coverage. Secondly, satellite communications have a long communication range and large capacity. It is worth mentioning that the Ministry of Industry and Information Technology recently issued a document clarifying the Tiantong-1 satellite phone, requiring that the Tiantong-1 satellite phone dedicated for emergency communications will only be provided to members of the national emergency system and government emergency departments, and effective management and technical measures will be taken to conscientiously implement the responsibilities for the distribution and real-name registration of relevant satellite phone numbers xzturui.com
