A method of connecting a mobile terminal and an AP. The mobile terminal has a short-distance wireless communication module and a mobile communication module, and the AP provides a wired/wireless communication interface. The SID and NID of a network with the AP are stored as SID_Bond and NID_Bond at an initial bonding with the AP. It is determined whether a channel established with the AP has been terminated. If the channel is terminated, the SID_Bond and NID_Bond are compared with an SID and NID for the present position. If they are different, the short-distance wireless communication module is transitioned to a low-power mode.
