Method and device for enhancing Quality of Service in Wireless Local Area Network

摘要

The disclosure provides a method and device for enhancing Quality of Service (QoS) in a Wireless Local Area Network (WLAN). The method for enhancing QoS in the WLAN includes the steps of: adding a message category in a wireless access point (S10); adding a QoS priority transmission queue according to the added message category and setting queue attributes (S11); performing QoS scheduling by using the added transmission queue and performing data transmission (S12). The device for enhancing QoS in the WLAN can ensure that a wireless full service is carried out normally according to requirements of users by expanding the message categories in Enhanced Distributed Channel Access (EDCA) QoS, adding a wireless priority queue correspondingly, and using a policy of discarding a message intelligently and the like, thereby enhancing QoS to improve the user experience.

1. 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.
