Abstract: The present invention provides a data card and a method for Internet access of the data card. The method for Internet access of the data card includes: after the data card is connected to a host, mapping the data card into an Internet access device by using an Ethernet interface protocol; obtaining, by the data card, dial-up information, and dialing by using the dial-up information to request to connect to a network; and performing, by the Internet access device, communication between the host and the network. By using the technical solutions provided by embodiments of the present invention, fast Internet access may be implemented without installing a driver.

Abstract: A communication method for a host and a wireless Internet access module, and a data card, are provided so that the host implements wireless Internet access with the wireless Internet access module of a secure digital interface. The method includes simulating each port on a wireless Internet access processing function unit in a wireless Internet access module into a secure digital card partition and reporting the secure digital card partition to a host side; receiving downlink interaction information from the host side encapsulated in a secure digital card interface format, decapsulating the downlink interaction information, and delivering the decapsulated downlink interaction information to a corresponding port; and receiving uplink interaction information reported to the host side from each port, and encapsulating the received uplink interaction information in the secure digital card interface format.
