Patent ID: 8861454

Claim:
A method for enhancing Quality of Service (QoS) in a Wireless Local Area Network (WLAN), comprising: adding a message category in a wireless access point; adding a QoS priority transmission queue according to the added message category and setting queue attributes; performing QoS scheduling by using the added QoS priority transmission queue and performing data transmission, wherein the step of performing QoS scheduling by using the added QoS priority transmission queue and performing data transmission further comprises the step of: discarding a message when wireless bandwidth is insufficient and a buffer queue of a gateway is full; wherein the step of discarding the message further comprises the step of: determining whether the priority level of a newly added message is high priority; if so, discarding a message in a low priority queue, and putting the newly added message into a high priority queue; otherwise, discarding the newly added message; wherein before the step of discarding the message in the low priority queue, and putting the newly added message into the high priority queue, further comprises the step of: determining whether the length of the low priority queue is zero; if so, discarding the newly added message; otherwise, discarding a message in the low priority queue, and putting the newly added message into the high priority queue.
