摘　　要：由于移动互联网业务的快速发展,移动回传网络体现出大容量、分组化的特征,在LTE时代,运营商的移动回传网络要实现由MSTP向分组的转型。文章首先介绍IP RAN技术的特点和组网方案,然后搭建仿真平台对IP RAN和MSTP两种技术的承载效率进行定量分析。仿真结果表明,IP RAN与MSTP相比具有更高的传送效率,利用IP RAN技术建网后网络扩容的时间点相比MSTP技术得以推后,可降低LTE时代移动回传网络的运营成本。As for the quick development of mobile Internet service, the mobile backhaul network is required to increase its capacity and give better support to packet service. In the period of LTE, operators＇ mobile backhaul networks need to be upgraded from MSTP to packet transport technologies. This paper introduces the IP RAN technology and its networking scheme at first, and then we built a simulation testbed to compare the transport efficiency of IP RAN and MSTP technology. Simulation results show that the IP RAN postpones the time point of network expansion for its higher transmission efficiency, so the OPEX for LTE network can be reduced significantly.
