In some high-density scenarios such as exhibitions and stadiums, a large number of users may connect to a single radio or VAP if the number of access users on the radio or VAP is not limited. These users work on the same channel, and concurrent services and air interface competition may occur, degrading user experience.
In these scenarios, the number of users on a radio or VAP is typically limited to ensure user experience. Once the maximum number of access users is reached, new users are not allowed to access the network. However, such configuration may cause a failure for VIP users to access the network, therefore degrading access experience of VIP users.
Preferential access of VIP users allows VIP users to access the network and disconnects online non-VIP users when the number of access users reaches the maximum. This therefore ensures access experience of VIP users.
