Communication methods for host and wireless Internet access module and host communication module

Abstract

The embodiment of the invention discloses communication methods for a host and a wireless Internet access module and a host communication module to realize that the host performs wireless Internet access through the wireless Internet access module of a secure digital interface. One method comprises the following steps of: receiving secure digital card subarea information reported by the wireless Internet access module of the secure digital card interface; providing a virtual serial device and a virtual modulation / demodulation device corresponding to a subarea for an application layer; and mapping the communication of the application layer, the virtual serial device and the virtual modulation / demodulation device to the corresponding secure digital card subarea of the wireless Internet access module of the secure digital card interface. The other method comprises the following steps of: modifying a hardware ID of the wireless Internet access module of the secure digital card interface; and creating a serial device and a modulation / demodulation device according to the secure digital card subarea information so as to establish communication between the application layer and the corresponding secure digital card subarea of the wireless Internet access module of the secure digital card interface through the serial device and the modulation / demodulation device.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a wireless Internet access module, a communication method with a host, and a data card. Background technique [0002] With the development of wireless data services, wireless Internet access modules are more and more accepted due to their considerable uplink and downlink rates, simplicity and convenience, and other business features. Described wireless Internet access module adopts independent interface to be connected with computer usually, for example USB (Universal Serial Bus Stick, Universal Serial Bus), PCI-E (Peripheral Component Interconnect express, peripheral component interconnection fast transmission standard), Mini PCI-E ( Micro PCI-E) or PCMIA (Personal Computer Manufacturer Interface Adaptor, personal computer manufacturing interface standard) interface, etc. The combination of the wireless Internet access module and the computer can constitute a ...
