On July 30, the beidou-3 short message communication service achievement conference was held in Beijing. China Ordnance Industry Group Co., Ltd. and China Mobile Communications Group Co., Ltd. jointly demonstrated the new functions of the Beidou short message communication service of the Volkswagen smart phone, as well as the satellite ground integration solutions and technical solutions based on the beidou-3 short message communication service. This marks that the short message communication service of the beidou-3 system has entered a new stage of the development of the mass application from the industrial application. Short message communication is a unique service of Beidou system that is different from other global satellite navigation systems. The short message communication service of beidou-3 system covers China and surrounding countries and regions. It has the characteristics of low cost, wide coverage, high reliability and random access. It can effectively supplement the ground mobile communication network to meet the service needs of China's economy and Society for emergency communication, search and rescue in areas without ground network coverage. According to Yan Zhe, deputy general manager of China Ordnance Industry Group Co., Ltd., as an important part of the national emergency system, short message communication services play an active role in people's livelihood support, disaster relief and mitigation, field search and rescue, marine fishery, transportation, border patrol and other aspects. The short message communication application service platform of beidou-3 system, which has been completed synchronously, provides a strong support for the efficient, safe and standardized management of short message communication services, and improves the short message communication service capacity and level qualitatively. China Ordnance Industry Group Co., Ltd., in conjunction with China Mobile Communications Group Co., Ltd., China Electronics Technology Group Co., Ltd. and domestic mobile phone manufacturers, has overcome a number of key core technologies, completed the research and development of the first mobile phone Beidou short message communication RF baseband integrated chip in China, and innovated and realized the "No. 1 dual network" design of popular mobile phones that "do not change cards, numbers, and add peripherals", For the first time, it realized the satellite communication capability of Volkswagen smart phones, effectively solving the problem of "not in the service area". Yang Changfeng, chief designer of the Beidou satellite navigation system project and academician of the Chinese Academy of engineering, said: "we have successfully broken through a series of major key technologies, successfully completed the beidou-3 short message communication service platform, and is the first in the world to integrate the short message communication service into the mass mobile phone. This is another major achievement of Beidou's innovative development." (news agency)
