Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] Secure Digital Memory Card (secure digital memory card) is called for short SD card (the application document of the present invention adopts the name of SD card later), and standard size is 32mm * 24mm * 2.1mm. The SD card combines SanDisk's flash memory card control and MLC (Multilevel Cell, multi-level cell) technology with Toshiba's 0.16u and 0.13u NAND (Not AND, NAND gate) technology , Connect with a dedicated driver through a 9-pin interface. The 9-pin interface can be connected in two ways, which are Secure Digital Input and Output (SDIO for short) and Serial Peripheral Interface (SPI for short). Figure 1A Shown is the appearance of the SD card and the schematic diagram of the 9-pin interface interface. Among them, the n...

Abstract

The embodiment of the invention discloses a wireless internet module and a communication method and a data card for same and host, so as to realize wireless internet for the host through a secure digital interface. The method comprises the following steps: simulating each port on the wireless internet processing function unit of the wireless internet as a secure digital card partition and reporting to the host side; receiving encapsulated downlink mutual information in the form of secure digital card interface from the host side and then sending the same after being decapsulated to corresponding ports; and receiving uplink mutual information reported to the host side from each port, and sending to the host side after encapsulating the uplink mutual information in the form of secure digital card interface. The wireless internet module comprises an adaptive unit which is used for communication between the host side and wireless internet processing function unit. The digital card is a standard secure digital card or a micro secure digital card or a mini-secure digital card in outline, comprising a 9-pin secure digital card interface and the wireless internet module.

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 ...
