APPARATUS AND METHOD FOR AVOIDING INTERFERENCE DURING A CALL IN A PORTABLE TERMINAL

摘要

Provided are a method and apparatus for avoiding interference during a call in a portable terminal that supports Unlicensed Mobile Access (UMA). The method includes measuring a Carrier to Interference and Noise Ratio (CINR) of a channel in which a call is established, and comparing the CINR with a predetermined first threshold; if the CINR of the channel is greater than the first threshold, searching for a peripheral channel and measuring a CINR of the peripheral channel; comparing the CINR of the peripheral channel with a predetermined second threshold; and if the CINR of the peripheral channel is less than the second threshold, determining that is a handover to be performed to the peripheral channel.
