Discovery and selection method, equipment, system and terminal of wireless local area network (WLAN)

Abstract

The embodiment of the invention provides a discovery and selection method, equipment, system and terminal of a wireless local area network (WLAN). The method comprises the following steps of: when initiating packet switch data to a cellular network, sending a registration request to the discovery and selection equipment of the wireless local area network; receiving a notification message sent by the discovery and selection equipment of the wireless local area network when determining that the wireless local area network needs to be used to offload the packet switch data in the cellular network, wherein the notification message carries access parameter information; and selecting a target wireless access point according to the access parameter information. With the technical scheme provided by the embodiment of the invention, when a terminal initiates the packet service data to the cellular network, the operation of discovery and selection of the WLAN are carried out, and thus the efficiency of discovery and selection of WiFi (Wireless Fidelity) can be effectively improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method, device, system and terminal for discovering and selecting a wireless local area network. Background technique [0002] Wireless fidelity (wireless fidelity; WiFi) is a kind of terminal that can connect personal computers, handheld devices (such as personal digital assistants (Personal Digital Assistant; PDA), mobile phones) and other terminals wirelessly to wireless local area networks (Wireless Local Area Networks; WLAN )Technology.
