METHOD AND APPARATUS FOR HAND-OFF OF CALL-IN-PROGRESS ABSTRACT: A method and apparatus for a hand-off of a call-in- progress according to the present invention is arranged such that both a first ratio of a length of time, in which a measured value of SNR is below a predetermined "threshold" to a total length of the measuring time, and a second ratio of a length of time, in which a measured value of RSSI is below a predetermined "threshold", to a total length of the measuring time are detected and that the first ratio func- tions mainly when the "threshold" of RSSI is predetermined to a relatively low value; and the second ratio functions mainly when the "threshold" of RSSI is predetermined to a relatively high value, thereby optimizing the hand-off timing.
