FIELD: information technology; physics.
SUBSTANCE: retransmitter contains a high-speed frequency shift keyer unit, which modulates forward link signal frequency with identifying high-speed latent frequency labelling, when it passes through the retransmitter. A mobile station, which is used to receive large number of forward link pilot signals and identification of high-speed latent frequency labelling resonance signal, contains a receiver to receive signals of forward link, tracking frequency circuit to provide accurate demodulation of forward link signals, advanced forward link trilateration (AFLT)- a probe for detection of pilot signals and performance of pilot signal phase change, to measure time of receiving multiple forward link pilot signals; the system of retransmitter identification, configured so that to provide a capability of latent labelling detection and identification, and thereby identification of forward link retransmitted signal. The method of defining data to determine mobile station location in the forward link of multiple pilot signals implies AFLT-search of the mobile station to detect pilot signals and to measure the earliest time of pilot signal arrival of multiple pilot signals. Then, the first pilot signal is selected, AFLT-search for the retransmitter in the first pilot signal mentioned. Afterwards, upon finding a resonance signal of high-speed latent frequency labelling, which identifies retransmitted signal, sorting of the rest of selected pilot signals by retransmitters. Along with it, the pilot signal phase change data and information about retransmitters of the pilot signals, found by AFLT-search, is transferred to mobile station location detection system or to network location detection unit.
EFFECT: decrease of mobile station detection or identification time period.
