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

A wireless Internet access system, comprising:

• a host device;
• a data card that is provided with an antenna, a radio frequency unit, and a baseband processor, wherein the data card communicates with the host device by use of a secure digital interface and comprises a wireless Internet access module;
• wherein the wireless Internet access module is configured to simulate a device management port and a modem port on a wireless Internet access processing function unit on the wireless Internet access module into a secure digital card partition and report the secure digital card partition to the host device;
• wherein the host device is configured to receive information of the secure digital card partition reported by the wireless Internet access module, to load a serial port driver and a modem driver corresponding to the wireless Internet access module, to encapsulate a command or data delivered by an application layer to the device management port or modem port into a secure digital card interface format, and to map the encapsulated command or data to a corresponding secure digital card partition of the wireless Internet access module;
• and
• wherein the wireless Internet access module is configured to receive the command or data encapsulated in the secure digital card interface format from the host device, to decapsulate the encapsulated command or data, and to transfer the decapsulated command or data to the corresponding device management port or modem port, so as to manage the wireless Internet access module through the device management port or implement dial-up Internet access through the modem port;
• wherein being configured to simulate the device management port and the modem port and report the secure digital card partition to the host side comprise:
• being configured to obtain configuration information of the device management port and the modem port of the wireless Internet access processing function unit;
• being configured to generate secure digital card partition information separately corresponding to the device management port and the modem port according to the configuration information;
• being configured to interact with the host side according to an initialization process of a secure digital card;
• and
• being configured to report the secure digital card partition information to the host side.
