Method and device for enhancing service quality in wireless local area network

Abstract

The invention discloses a method and a device for enhancing service quality in a wireless local area network. The method for enhancing the service quality in the wireless local area network comprises the following steps: adding packet classification to a wireless access point; adding a QOS priority level transmission queue according to the added packet classification and setting a queue property; and performing QOS dispatching by using the added transmission queue and performing data transmission. The device for enhancing the service quality in the wireless local area network can ensure that a wireless full service is normally performed according to the requirement of a user by strategies of expanding the packet classification in EDCA QOS, correspondingly adding a wireless priority level queue, intelligently dropping a packet and the like, so that the service quality is enhanced to improve user experience.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for enhancing service quality in a wireless local area network. Background technique [0002] As a way for users to access the network, wireless local area network (WLAN) has advantages that cannot be compared with wired access: simple wiring and easy mobility. And with the evolution of technology, the bandwidth of wireless LAN is also increasing day by day. However, in terms of QOS (Quality of Service, quality of service), currently only EDCA (Enhanced Distributed Channel Access, Enhanced Distributed Channel Access) QoS in IEEE802.11e can meet data service transmission, while full service (data, voice and video, etc.) is clearly insufficient. [0003] EDCA QOS has the following limitations: 1. There are only four categories of messages, namely AC_BE, AC_BK, AC_VI, and AC_VO, and the corresponding priority queue has only four levels, which cannot meet t...

However, in terms of QOS (Quality of Service, quality of service), currently only EDCA (Enhanced Distributed Channel Access, Enhanced Distributed Channel Access) QoS in IEEE802.11e can meet data service transmission, while full service (data, voice and video, etc.) is clearly insufficient

[0003] EDCA QOS has the following limitations: 1. There are only four categories of messages, namely AC_BE, AC_BK, AC_VI, and AC_VO, and the corresponding priority queue has only four levels, which cannot meet the needs of all business scenarios; 2. EDCA QOS is Relative priority, in the case of a bad environment, the business with high priority will also be affected; for example, in home applications, when the IPTV (Interactive Internet TV) service and Internet service are carried out at the same time, the user is most concerned about the IPTV service. Users cannot accept the occurrence of mosaics or video pauses and delays, while the impact on online services is relatively tolerable; the current EDCA QOS cannot fully guarantee high-priority services, such as guaranteeing priority IPTV services, etc.
