Based wireless local area network admission control method for mixing business guaranteed quality of service

The present invention discloses a mixed traffic wireless local area network access control method based on quality of service, the implementation steps comprising: initializing; when a packet is transmitted between the wireless access point with a user, if the user of a the user has access to, the measurement parameters, if the user is to be accessed by a user, the parameter setting, and allowing to be accessed sequentially calculated under the assumption that the user access to each user at any one time slot a packet transmission probability, the probability of a packet delay distribution service functions and network can guarantee the quality of service in all probability the user; if the probability that the network can guarantee the quality of service for all users is not less than a preset threshold, the user is allowed to be accessed access to, or refuse. The present invention is applicable to the presence of the user and the service link rate difference parameters between the real network environment, and can guarantee the quality of service at a certain probability that the user's wireless LAN, can be used for admission control in a WLAN.
