Title: Apparatus and method for time synchronization

Abstract: An apparatus for time synchronization of a femtocell base station receives, via neighboring macrocell base stations adjacent to a femtocell base station, timing packets generated by timing servers directly connected to the neighboring macrocell base stations, and if time synchronization using a GPS satellite is impossible, obtains system time information from a timing packet received via one corresponding to a master base station, among the neighboring macrocell base stations, and performs time synchronization.
