Luo Jianhong1, Fan Zhiwen2, Wang Hongbin1, et al. Study on synchronization for PTN-based node B of TD-SCDMA[J]. 2009,(2):16-18. DOI: 10.13756/j.gtxyj.2009.02.019.
As a packetized network with transmission functions
Packet Transport Network(PTN) is mainly used for the IP service bearing of Radio Access Networks(RAN).Hence
its time synchronization is of major significance.This paper introduces the PIN synchronization demands and the IEEE 1588 sync technologies
describes the requirements and methods of PTN transport time synchronization and discusses the synchronization solutions of PTN-based node B of TD-SCDMA.
