摘要

Method and apparatus for synchronizing base stations (30n) employing an independent synchronous source or identifying a base station (30n) as a master source. An RNC (C-RNC) (36, 38, 40) or a base station (30n) may designate one base station (30n) or UE (20, 22, 24) to acquire measurements derived from base stations (30n) to achieve synchronization. Synchronization activities may be regularly scheduled or may be undertaken when periodic measurements indicate that a drift value exceeds a given threshold.
