A METHOD FOR IMPROVE OF THE HANDOVER PERFORMANCE IN SUBWAY AND THE SYSTEM THERE OF

摘要

PURPOSE: A method for enhancing mobile phone handover performance in an underground section and a system therefor are provided to achieve a smooth mobile communication handover when a mobile subscriber passes through a long distance underground section in a call-connected state. CONSTITUTION: The first distributor(20) receives and distributes the output signal of a base station(10) installed every subway station. The first signal transport part(21) receives the output signal of the first distributor(20) and connects it to a leakage coaxial cable. A low loss transport path(23) transfers the output signal of the first signal transport part(21) without data loss. The second signal transport part(22) receives and processes the output signal of the first signal transport part(21) transferred through the low loss transport path(23). The second distributor(30) receives and distributes the output signal of the second signal transport part(22). The first leakage coaxial cable(35) and the second leakage coaxial cable(36), respectively connected to the output side of the second distributor(30), are extended toward their respective subway stations in order to form handover areas inside the subway stations of platforms.
