Abstract
Method and system for synchronization of base stations in a mobile communications network, in particular for the purpose of a seamless handover, time information is transmitted, possibly on request, to the base stations from a time information server via a local area network. Since base stations which are involved in a seamless handover are generally adjacent, and the respective propagation times and/or propagation time fluctuations of time information differ only slightly in the local area network between the time information server and the base station when the base stations are adjacent, highly accurate synchronization may be achieved, especially for a seamless handover.
