Abstract:
1. A method for synchronization of base stations in a mobile communications network, the method comprising the steps of: transmitting time information via a packet-oriented local area network to the base stations; adjusting a clock transmitter for a respective base station which receives the time information based on reception time and time information content of the time information; controlling functional sequences of respective base stations, which relate to a transmission of radio time frames, based on signals from the clock transmitter; temporarily storing a data stream, which is received via the local area network from a base station, in an input buffer store which operates on a first-in-first-out principle; reading data elements from the data stream for further processing using a clock cycle governed by the clock transmitter; recording a filling level over the input buffer store; and readjusting the clock frequency of the clock transmitter based on the recorded filling level, wherein the adjustment of the clock transmitter based on the received time information is given priority over the adjustment of the clock transmitter based on the recorded filling level.
