TD-LTE EPC组Pool传送方案研究

Research on the TD-LTE transmission plan of EPC Pool

随着我国4G牌照的发放,中国移动开始大规模部署TD-LTE网络,采取了LTE EPC集中部署、PTN回传等组网方案及技术。本文从LTE回传现状出发,重点讨论EPC组Pool的传送方案,并结合规划实例进行说明,提出L3 PTN带宽规划和设备选型的相关建议,为EPC组Pool传送网建设提供参考。

As the 4G licenses were officially issued, China Mobile has a large-scale deployment of LTE base station also puts forward some requirements, such as the centralism construction of EPC, and the employment of PTN technology. This paper starting off the analysis of the actuality that LTE base station adopting PTN technology, focus on the TD-LTE transmission plan of Pool composed by EPC, provides some networking scheme that do apply to China Mobile LTE transport network, and gives some further living examples of Pool, put forward some relevant suggestions on network bandwidth planning and equipment selection as references.
