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, encapsulating the received uplink interaction information in the secure digital card interface format, and sending the encapsulated uplink interaction information to the host side. |

1. A wireless Internet access device, comprising:
a processor; and a computer-readable storage memory storing a program to be executed by the processor, the program including a plurality of software modules including:
a secure digital card interface software module, wherein the secure digital card interface software module is configured to, after it is detected that an electrical connection is established with a host side, receive downlink interaction information from the host side or send uplink interaction information to the host side;a wireless Internet access processing software module, wherein the wireless Internet access processing software module is configured to process the downlink interaction information from the host side, so as to implement wireless Internet access; andan adaptation software module, wherein the adaptation software module is configured to decapsulate the downlink interaction information encapsulated in a secure digital card interface format from the host side and received by the secure digital card interface software module, to deliver the decapsulated downlink interaction information to a corresponding port of the wireless Internet access processing software module, to receive the uplink interaction information reported to the host side from the port, to encapsulate the received uplink interaction information in the secure digital card interface format, and to send the encapsulated uplink interaction information to the host side through the secure digital card interface software module, wherein the adaptation software module comprises:a secure digital card partition information generation software sub-module, configured to obtain configuration information of each port of the wireless Internet access processing software module, and to generate secure digital card partition information separately corresponding to each port according to the configuration information;a secure digital card partition information report software sub-module, configured to interact with the host side according to an initialization process of a secure digital card, and to report the secure digital card partition information to the host side; anda secure digital card partition mapping software sub-module, configured to separately map a generated partition to a corresponding port of the wireless Internet access processing software module. |
