摘要
中国电信大量使用卫星传输技术传输应急基站信号,为降低数据配置复杂度,提高卫星带宽使用效率,应急基站可以应用IP技术传输3G信号。本文探讨了在中国电信主流卫星调制解调器和应急基站E1接口之间应用IP传输技术,简化了数据配置的方法,并在中国电信上海卫星地面站开展验证测试,实地验证了IP传输技术的应用效果。
China Telecom backhauls CDMA BTS link over satellite under emergency situations. To improve the satellite link efifciency, reduce the complexity of re-conifguration of mobile system, the deployed E1 based 3G BTS could be carried by IP. This research is focusing on converting the E1 connection between BTS/BSC and satellite modem, which China Telecom primarily used, into IP transmission, and simpliifes the BSC data re-conifguration. The result was also conifrmed by live-environment test at an earth station in Shanghai.
