PURPOSE: To provide TDM synchronizing method/system among mobile communication base stations, which can solve the problem that call synchronizing signals transmitted from peripheral base stations cannot instantaneously be synchronized. CONSTITUTION: The TDM synchronizing method/system among the mobile communication base stations are provided which receive and store the call signals by a phase delay correction part 11 in the respective peripheral base stations 2 when a central base station 1 simultaneously transmits the call signals to the plural peripheral base stations 2, generate GPSCLK of a one second period by a GPS reception part 13 based on GPS time transmitted from a GPS satellite 20, output a value (phase delay information) obtained by counting time till GPSCLK from the call signal to the phase delay correction part 11 by a phase delay detection part 12, read the call signal with delay by changing a read address from a storage part 11a only by an amt. of address based on phase delay information by the phase delay correction part 11 and as a result, transmit the call signal at the timing of next GPSCLK. |
