1. A method for a wireless access point for operating wireless local area network cards in a power-saving mode in a wireless communication system, the method comprising following steps:

(a) storing data to be transmitted to the wireless local area network cards, or WLAN cards, operating in the power-saving mode in the wireless access point of the wireless communication system;

(b) receiving aging times of the WLAN cards operating in power-saving mode according to durations of the WLAN cards waiting for receiving the data stored in the wireless access point;

(c) when the aging times of the WLAN cards operating in power-saving mode 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 operating in power-saving mode in step (a); and

(d) when sizes of all the data stored in the wireless access point corresponding to the WLAN cards operating in power-saving mode 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 operating in power-saving mode in step (a) according to a WLAN-card adding rule.
