Abstract: A method for a wireless access point for operating WLAN cards in a power-saving mode in a wireless communication system. The method includes: (a) storing data to be transmitted to the WLAN cards in the wireless access point of the wireless communication system; (b) receiving aging times of the WLAN cards according to durations of the WLAN cards waiting for receiving the data stored in the wireless access point; (c) when the aging times are smaller than a default, comparing unit-data-transmission amounts of the WLAN cards with the data stored in the wireless access point corresponding to the WLAN cards; and (d) when all the data stored in the wireless access point corresponding to the WLAN cards are less than the unit-data-transmission amounts of the WLAN cards, sequentially transmitting the data stored in the wireless access point corresponding to the WLAN cards according to a WLAN-card adding rule.

Abstract: A method for accessing discrete data includes transmitting a write command to a memory, determining whether each data following a header of the file needs to be encrypted according to a data format of a file that is to be written into the memory, transmitting the file header and each data following the file header to a logic unit, turning on the logic unit for encrypting the data determined to be encrypted and writing the encrypted data into the memory, turning off the logic unit for writing the data determined not to be encrypted into the memory directly, and sending a first response signal from the memory when the writing of the file is finished.
