When the application B needs to forward the packet to the terminal B, the industry application B first sends the packet to the service gateway B that is connected to the service. The service gateway B extracts the destination terminal identifier from the packet, and passes the remote terminal according to the destination terminal identifier. The routing table is queried to the next hop of the current forwarding. The next hop of the current forwarding is the service gateway A. Then, the terminal information and the service information corresponding to the packet are obtained according to the terminal subscription relationship, and corresponding to the packet. The terminal information and the service information and the predetermined priority policy insert the message into the predetermined forwarding queue of the corresponding priority, and control the predetermined forwarding queue to forward the message to the service gateway A; the service gateway A checks whether the terminal B is in the online state. If online, the terminal information and the service information corresponding to the packet are obtained according to the terminal subscription relationship, and the packet is inserted into the predetermined forwarding queue of the corresponding priority according to the terminal information and the service information corresponding to the packet and the predetermined priority policy. The control predetermined forwarding queue forwards the message to the terminal B.
