Wireless internet access module, communication method for host and wireless internet access module, and data card

摘要

Embodiments of the present invention relate to wireless Internet access, a communication method for a host and a wireless Internet access module, and a data card, 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 encapsulated in the secure digital card interface format, and delivering the decapsulated downlink interaction information to a corresponding port; and receiving uplink interaction information reported to the host side from each port, encapsulating the received uplink interaction information in the secure digital card interface format, and sending the encapsulated uplink interaction information to the host side. The wireless Internet access module includes an adaptation unit, configured to implement communication between a host side and a wireless Internet access processing function unit. The data card has a form of a shape of a standard secure digital card or a micro secure digital card or a mini secure digital card, and includes a 9-pin secure digital card interface and the wireless Internet access module.
