Typical applications of telecommunication services mainly include telecommunication backhaul, terrestrial network backup and emergency response support to mobile base stations. 4G/5G base station backhaul uses satellite high-speed communication to provide operators with 4G/5G mobile base station emergency communication services , and can provide operators with temporary base station backhaul services at major events. At the same time, satellite communication can provide fast link deployment, safe and reliable communication support to terrestrial networks, effectively playing the role of "trunk backup". Our service solves the difficulties which telecom operators face with the construction of networks, cost and network efficiency in remote areas. The disaster-resistant super base station is a typical application for emergency protection. In areas where disasters frequently occur, satellite communication terminals are set up to provide backup backhaul links for the base stations via China Satcom satellites. The automatic switch between terrestrial and satellite networks serve to improve the disaster response capability of terrestrial network base stations. In addition, operators can deploy satellite emergency communication vehicles and portable VSAT stations to meet emergency communication requirements.
