driving, by the host device, the port by using a port driver corresponding to the port type according to the report obtained;
obtaining, by the host device, an IP address for the host device and an IP address for the wireless terminal which are assigned by the wireless terminal;
establishing, by the host device, a communication link that is based on the network layer data transfer protocol between the host device and the wireless terminal through interaction with the wireless terminal via the port according to the assigned IP address for the host device and the IP address of the wireless terminal; and
transmitting, by the host device, an IP packet containing a service packet and a type of the service packet via the communication link that is based on the network layer data transfer protocol so as to allow parsing of the service packet according to the type of the service packet, and
wherein the network layer data transfer protocol comprises an IP protocol, an SPX protocol/IPX protocol, or a NetBEUI protocol, and
the IP address for the host device and the IP address for the wireless terminal obtained by the host device are assigned by the wireless terminal using a Dynamic Host Configuration Protocol DHCP function of the wireless terminal.
8. The method according to claim 7 , wherein
the service packet and the type of the service packet are transmitted through data portion of the IP packet via the communication link based on the IP protocol.
9. The method according to claim 7 , wherein the wireless terminal is configured to have capability of a data card or machine-to-machine (M2M) wireless terminal.
10. The method according to claim 7 , wherein the type of the service packet comprises SCSI data, an AT command, IP data, or DIAG data.
