Mobile network device using a wireless SD card that uses SCSI to SD command conversion

摘要

A mobile network access device, system and method are disclosed. The method includes sending data or a command to a storing unit or a baseband processing unit according to a logical address in a Secure Digital (SD) command, where the SD command is a result of converting a Small Computer System Interface (SCSI) Command Descriptor Block (CDB) after a terminal device encapsulates the received data or command into the SCSI CDB. In the embodiments of the present invention, the wireless Internet access function is integrated into an SD card. The mobile network access device determines to send the data or command to the baseband processing unit or storing unit according to the logical address in the SD command, which reduces the size of the mobile network access device and enables developers to design smaller terminal products.

主权项

1. A mobile network access device, comprising:
a secure digital (SD) slave controller; a baseband processing unit; and a storing unit;
wherein the SD slave controller is configured to send data or a command to the storing unit or the baseband processing unit according to a logical address in an SD command,wherein the SD slave controller is further configured to send the data or command to the storing unit if the logical address in the SD command corresponds to any physical address and send the data or command to the baseband processing unit if the logical address in the SD command corresponds to no physical address;wherein the baseband processing unit is configured to send the data or command to an application module corresponding to the baseband processing unit if the SD slave controller sends the data or command to the baseband processing unit according to the logical address in the SD command; and the storing unit, configured to use a physical address corresponding to the logical address to read from and write to the storing unit according to the SD command if the SD slave controller determines to send the data or command to the storing unit according to the logical address in the SD command.
