PTN+PTN6900 LTE承载解决方案研究

PTN + PTN 6900 hosting solutions for LTE research

随着LTE网络的大规模发展,原有的PTN核心层网络(PTN+PTN3900)已不能满足业务发展需要,PTN核心层需要功能更强、设备容量更大以及高带宽端口密度更多的L3层才能满足业务发展需要。本文主要探讨了承载LTE业务的华为PTN设备组网研究,提出了SGW/MME本地市、异地部署方案;以及SGW、MME对接一系列解决方案,详细描述了PTN+PTN6900系列功能强大的核心层设备的组网方式,为后期大规模LTE发展提供了更完善、更低成本的移动承载网络。

With the development of large-scale LTE network, the original core layer PTN network （PTN＋PTN3900） can not meet the needs of business development, PTN core layer requires more powerful equipment capacity greater port density and high bandwidth more L3 layer in order to meet the business development needs. This paper discusses the business of Huawei LTE bearer network research PTN equipment proposed SGW / MME local city, remote deployment scenarios; and SGW, MME docking range of solutions, a detailed description of the PTN ＋ PTN6900 series of powerful core layer devices networking, to the late development of large-scale LTE provides better, more low-cost mobile carrier network.
