Abstract: PURPOSE: A method and an apparatus for maintaining synchronization between a base station and a mobile station in a time division duplexing frequency hopping multiple access system are provided to prevent synchronization from being missed at the mobile station due to system clock loss. CONSTITUTION: A present synchronization establishment degree is stored at a variable NFSI, a present receiving strength is stored at a variable NRSSI, and an average receiving strength until present is stored at a variable ARSSI(610). It is determined whether it is synchronized state at present(621). It is determined whether a window size and a preamble detect threshold value are after an initial set up(622). It is determined whether the NFSI corresponds to the value between the maximum value and the value obtained by subtracting Ox0F value from the maximum value(623). The window size and the pre-amble detect threshold value are set up as initial values(624). The value of the NFSI is stored at an OFSI representing the former synchronization establishment degree(625). It is determined whether the NFSI and the OFSI correspond to the value between the maximum value and the value obtained by dividing the maximum value by two(626). It is determined whether the difference between the NFSI and the OFSI is larger than or equal to 8(627,628). It is determined whether the difference between the average receiving strength until present and the present receiving strength is smaller than 6(627,628). It is determined whether the window size is smaller than the maximum value of the window size related to return to the original state(628). The window size is increased and the pre-amble threshold value is decreased since it is determined as loss state of system clock(629). The NFSI is stored in the OFSI(630).
