WIRELESS LOCAL AREA NETWORK DISCOVERY AND SELECTION METHOD, DEVICE AND SYSTEM, AND TERMINAL

摘要

Embodiments of the present invention provide a wireless local area network discovery and selection method, device, and system, and a terminal. The method includes: sending, when packet switched data is initiated to a cellular network, a registration request to a wireless local area network discovery and selection device; receiving a notification message sent by the wireless local area network discovery and selection device, where the notification message is sent when the wireless local area network discovery and selection device determines that a wireless local area network needs to be used to offload the packet switched data in the cellular network, and the notification message carries access parameter information; and selecting a target wireless access point according to the access parameter information. With the technical solutions of the embodiments of the present invention, the foregoing WLAN discovery and selection operations are performed when a terminal initiates packet service data to a cellular network, which can effectively improve efficiency of WiFi discovery and selection.
