Communication method of wireless terminal and host device according to a network layer data transfer protocol, wireless terminal, and host device

摘要

The present invention provides a communication method for a wireless terminal and a host device, a wireless terminal, and a host device. The method includes: reporting, by a wireless terminal, a port type of a port corresponding to the wireless terminal to a host device, where the port type is based on a network layer data transfer protocol, so that the host device drives the port by using a port driver corresponding to the port type; establishing, by the wireless terminal, a communication link that is based on the network layer data transfer protocol between the wireless terminal and the host device through interaction with the host device via the port; and transmitting, by the wireless terminal, a service packet and a type of the service packet via the communication link that is based on the network layer data transfer protocol.

主权项

1. A communication method for a wireless terminal, comprising:
sending, by a wireless terminal, a report including a port type of a port corresponding to the wireless terminal to a host device based on a network layer data transfer protocol and assigning, by the wireless terminal, an IP address for the wireless terminal and an IP address for the host device; establishing, by the wireless terminal, a communication link that is based on the network layer data transfer protocol between the wireless terminal and the host device through interaction with the host device via the port according to the assigned IP address of the wireless terminal and the IP address for the host device; and transmitting, by the wireless terminal, 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 wireless terminal and the IP address for the host device are assigned using a Dynamic Host Configuration Protocol (DHCP) function of the wireless terminal.
