Document Type and Number:
WIPO Patent Application WO/2015/009000
Kind Code:
A1
Abstract:
The present invention relates to a method and an apparatus enabling a terminal to obtain information required for a wireless LAN AP search from a cellular base station in order to use a wireless LAN service, and to access a wireless LAN AP having a low network load in a short time. The communication method of a terminal according to one embodiment of the present invention may comprise the steps of: switching a channel to an AP scanning channel, which is a channel for searching for a wireless LAN AP between the terminal and the wireless LAN AP; transmitting a wireless LAN AP search signal from the AP scanning channel; receiving, from the wireless LAN AP, a wireless LAN AP response signal, transmitted after an offset time set in accordance with the load state of the wireless LAN AP; and switching the channel to a data transmitting and receiving channel for data communications with the wireless LAN AP. According to one embodiment of the present invention, the terminal can always select the AP having the lowest load by performing a search on all surrounding wireless LAN APs.
