Abstract
The present disclosure describes promoting roaming of a wireless terminal in a wireless local area network (WLAN). The AP obtains signal quality and/or data transmission quality of the wireless terminal periodically, and determines whether the obtained signal quality and/or data transmission quality of the wireless terminal satisfies a predetermined threshold. Upon determining that the predetermined threshold is not satisfied, the AP proactively sends a probe response frame to the wireless terminal. The probe response frame notifies the wireless terminal of a wireless signal strength of the AP to promote roaming to a neighbouring AP.
Claims15
A method for promoting roaming of a wireless terminal in a wireless local area network (WLAN), the method being applicable at an access point (AP) and comprising:
- the AP obtaining signal quality and/or data transmission quality of the wireless terminal periodically;
- the AP determining whether the obtained signal quality and/or data transmission quality of the wireless terminal satisfies a predetermined threshold;
- and
- upon determining that the predetermined threshold is not satisfied, the AP proactively sending a probe response frame to the wireless terminal,
- wherein the probe response frame notifies the wireless terminal of a wireless signal strength provided by the AP to promote roaming to a neighbouring AP.
A network device for promoting roaming of a wireless terminal in a wireless local area network (WLAN), the network device being capable of acting as an access point (AP) and comprising memory to store executable instructions, an interface to communicate with the wireless terminal and a processor to:
- obtain signal quality and/or data transmission quality of the wireless terminal periodically;
- determine whether the obtained signal quality and/or data transmission quality of the wireless terminal satisfies a predetermined threshold;
- and
- upon determining that the predetermined threshold is not satisfied, proactively send a probe response frame to the wireless terminal,
- wherein the probe response frame is proactively sent to notify the wireless terminal of a wireless signal strength provided by the AP to influence wireless signal strength sensing at the wireless terminal and promote roaming to a neighbouring AP.
