Wi-Fi network access method and wireless access device

Abstract

The embodiment of the invention provides a Wi-Fi network access method and a wireless access device. The method comprises the steps that the wireless access device acquires the cell identifier of the current service cell; whether the position information of a Wi-Fi AP which is corresponding to the cell identifier of the current service cell exists in a position mapping relation table is searched, wherein the position mapping relation table comprises the cell identifier of each cell in which the wireless access device resides before and the position information of the corresponding Wi-Fi AP, and the position information the Wi-Fi AP comprises the SSID and the working channel of the Wi-Fi AP; and if the position information of the Wi-Fi AP which is corresponding to the cell identifier of the current service cell is searched in the position mapping relation table, the wireless access device sends a detection request frame with the SSID to the Wi-Fi AP in the working channel. According to the Wi-Fi network access method and the wireless access device, which are provided by the embodiment of the invention, the scanning time is shortened, and a mobile terminal can quickly access the Wi-Fi AP.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a Wi-Fi network access method and wireless access device. Background technique [0002] With the development of mobile communication networks, Wireless Local Access Network (WLAN) has been widely deployed and used as a local area communication network with convenient access, fast speed and relatively low price. To access a Wi-Fi access point (Access Point, hereinafter referred to as: Wi-Fi AP) and use Wi-Fi services, you must first find a Wi-Fi AP. This process is called scanning. The scanning time is effectively shortened, and the access process of the mobile terminal can be accelerated. [0003] In the prior art, the process of active scanning is that the Wi-Fi access module of the mobile terminal sends a probe request (Probe Request) frame to the Wi-Fi AP on all channels or on a designated channel, and sends a Probe Request frame to the Wi-...
