根据主流移动通信网所需的时间同步精度要求,对地面传送网支持同步信号传递取代卫星同步信号的各种方案进行分析,得出1588V2(IEEE Std1588-2008)技术方案从传送网改造、时间精度满足度方向上最为合适。同时,还对1588V2协议的组网方案进行研究,完成了现网1588V2时间精度组网测试、站点相应测试和业务效果测试,得出1588V2可良好的应用于TD-SCDMA网络的结论。
According to the requirements of time synchronization accuracy required by the mainstream mobile communication networks, various schemes for supporting synchronous signal transmission instead of satellite synchronization signals for terrestrial transmission networks are analyzed, and the technical solution of 1588V2 (IEEE Std 1588-2008) is transformed from transmission networks to time precision The most appropriate direction of satisfaction. At the same time, it also studied the networking scheme of 1588V2 protocol, completed the 1588V2 time precision network test, the site corresponding test and business effect test, and concluded that 1588V2 can be well applied to TD-SCDMA network.
