The meteorological SMS (Short Message Service) has a history of more than ten years in the meteorological department. It has a wide coverage. The message can provide 70 words of text service at most because it is limited by the technical capability of the traditional SMS gateway. In 2020, as the three major operators jointly released the “5G News (5GMC) White Paper”, RCS (Rich media communications) was launched. The technology can integrate voice, message, video, community network and other functions, providing technical support for the overall upgrading of traditional short message business. Based on the RCS UP1.0 standards generally supported by mobile terminals, a “5G weather compass produce and release support system” is studied and established to provide multimedia weather messages in pictures, videos and so on. The system can also enable non-5G users to achieve 5G messages by means of MMS (Multimedia Messaging Service) pullback through the Chatbot NFS (Network File System) fall technology. It iteratively updates traditional weather messages and obtains good operation effects.
