发明名称 METHOD AND ARRANGEMENT FOR SYNCHRONIZATION OF BASE STATIONS IN A MOBILE COMMUNICATIONS NETWORK
摘要 In order to synchronize base stations (BS1, BS2), in particular, for the purpose of conducting a seamless handover, time information (ZI1, ZI2) is transmitted optionally on demand by a time information server (VE) via a loc al network (LAN) to said base stations (BS1, BS2). The invention can be used to attain a high level of synchronization precision, especially for conducting a seamless handover, since base stations (BS1, BS2) involved in conducting a seamless handover are normally adjacent and, in the case of adjacent base stations, the respective transit times or transit time variations of an item of time information (ZI1, ZI2) differ only slightly in the local network (LA N) between the time information server (VE) and the base station.
