and the registration packet of the DTU-DSC is used for DTU identity authentication, ensuring the reliability of a communication link and enabling the DTU to be always online. The equipment works in an unattended station for a long time, the watchdog ensures the reliable operation of the CPU, and the registration packet ensures the reliable transmission of the equipment data. Each time the device is powered on again, the DTU identity, the local mobile IP address and the local mobile port number are reported to the DSC. If the device is not online for a long time, the mobile operator will recover the IP address and the port number, so that the IP address and the port number may be different when the device logs in again each time, and all DTUs need to report their own IP addresses to the DSC each time the DTUs are powered on.
