Problems solved by technology

[0004] However, when the vehicle-mounted Tbox is in the Stanby state, the server needs to go through the SMS process to trigger the service. Specifically, the server needs to obtain the power management status of the vehicle-mounted Tbox, and complete the data service from MQTT to the SMS protocol through the MQTT Fallback SMS mechanism. Both the on-vehicle Tbox and the server are established based on PS/CS two sets of protocols to complete the Internet of Things business, which makes the internal process of the on-vehicle Tbox IoT business code cons
