Abstract
The present invention discloses a method, an apparatus, and a system for synchronizing time, and relates to communication technologies. The method includes: receiving a time synchronization signal which includes a One Pulse Per Second (1PPS) and an absolute time data; and sending the time synchronization signals to the client through a wired medium to synchronize time. The apparatus includes a receiving module and a sending module. The system includes a time synchronization apparatus and a client. Time synchronization is implemented through an existing wired medium between base stations to accomplish μs-level time synchronization between indoor base stations without extra cabling.
