Embodiment Construction

[0023] The features and implementation methods of the present invention will be described in detail below in conjunction with the drawings and embodiments, the content is enough to enable anyone familiar with the relevant art to easily and fully understand the technical means used to solve the technical problems of the present invention and implement them accordingly, thereby realizing The effect that the present invention can achieve.

[0024] In the present invention, a wireless access control device (Wireless Access Controller, WAC) connected to an access point (Access Point, AP) determines that there is a first access point around the mobile device (station, STA) that is more connected than the current one. When there is a second access point with better connection quality, the mobile device is notified to roam from the first access point to the second access point.

[0025] In the present invention, the access point connected to the mobile device 100 before roaming is cal...

Abstract

The invention discloses a roaming system selecting access points through a wireless access control device and a method thereof. Through a technological means that after access points of a mobile device are detected, the signal strength between each access point of the mobile device and the mobile device is transferred to a wireless access control device, and then the wireless access control device instructs the mobile device to select an online access point according to the signal strength between each access point and the mobile device, the network online quality and data transmission efficiency of the mobile device can be considered concurrently, and the technical efficacy of high-speed roaming can be achieved.

Description

technical field [0001] A roaming system and its method, in particular a roaming system and its method in which an access point is selected by a wireless access control device. Background technique [0002] Roaming (roaming) refers to a behavior that occurs when a mobile device (station, STA) is switching from a wireless signal coverage of a first access point (Access Point, AP) to a wireless signal coverage of a second access point. [0003] In the current roaming technology, mainly using WiFi technology, different access points can monitor each other's characteristics on the same channel and within a certain distance, so that the access point can detect that the mobile device has moved to two The intersection area of ​​the wireless signal coverage of two access points. Among them, the method of judging that the mobile device has moved to the intersection of the wireless signal coverage of two access points is usually determined by the mobile device itself, so the mobile de...
