APPARATUS AND A METHOD FOR IMPROVING CALL DROP IN A MOBILE COMMUNICATION TERMINAL BY PREDICTING CALL DROP DURING A CALL

摘要

PURPOSE: An apparatus and a method for improving call drop in a mobile communication terminal are provided to prevent call drop during a call by receiving a new channel through handover when the call drop during a call is predicted.;CONSTITUTION: A receiving station(603) receives a signal from a serving base station, and a counter(609) is updated depending on whether or not a received signal succeeds in a decoding operation. A storage unit(611) stores the variation of the counter. If the counter value is same as or lower than the reference value, a control unit(607) predicts call drop during a call in consideration of the variation of the counter stored at the storage unit. If the call drop is predictable, the control unit requests the new channel from the serving station. The control unit sets up the initiation value of the counter according to the radio link timeout.;COPYRIGHT KIPO 2010
