Abstract
Provided is an apparatus and method for saving power in a dual mode portable terminal that concurrently supports a cellular network and an unlicensed band network. The method includes, upon disassociating from an in-association Access Point (AP) of an unlicensed band network, measuring a Received Signal Strength Indicator (RSSI) from the AP during a predetermined time and calculating an average value of the RSSI; and comparing the calculated average value with a predetermined threshold value and deciding whether to perform a mode conversion between a low power mode and a general mode.
