The IP address allocated to the second device by the fourth network element of the second device is an intranet IP address, the fourth network element of the second device maps to the intranet IP address or intranet IP address and port identification of the second device according to the extranet IP address or extranet IP address and port identification of the second device, and the control information is sent to the second device according to the content IP address or intranet IP address and port identification of the second device. At this time, CPE1 and CPE2 respectively allocate IP addresses and port numbers of 192.168.1.10:80 and 192.168.1.12:80 to the controller and the robot, and the controller accesses the robot with address 220.181.108.120, and converts the address into intranet IP and port identifier 10.5.0.110:80 (opposite end CPE ip+robot port number) through the user plane function unit or the firewall connected thereto, thereby accessing the robot and realizing remote control.
The foregoing detailed description of the invention has been presented for purposes of illustration and description, but is not intended to limit the scope of the invention, i.e., the invention is not limited to the details shown and described.
