Abstract:
A method for synchronization of base stations in a mobile radio network, comprising:transmitting a first synchronization signal from a first switching system part, causing a first base station, coupled thereto, to transmit radio frames which are aligned in time with the first synchronization signal; and transmitting a second synchronization signal from a second switching system part, causing a second base station, coupled thereto, to align its radio frame clock with the second synchronization signal, wherein the second base station receives the transmitted radio frames and determines a time error with respect to the radio frame clock, and transmits the time error to the second switching system part, and the second switching system part transmits a third synchronization signal to the second base station, with a transmission time selected as a function of the transmitted time error such that the radio frame clock of the second base station is synchronized with the radio frames of the first base station by time alignment with the third synchronization signal.
