数据业务密度图生成方法以及在TD—LTE网络规划中的应用

中国移动通信集团公司TD—LTE发展脚步的加快，TD-LTE网络规划成为重中之重。TD—LTE网络定位于高速数据业务，用于缓解目前GSM网络数据业务负荷过高的急迫问题，并且不同于GSM网络和TD—SCDMA网络，TD-LTE同频组网等特点决定了后期网络优化手段有限，因此，TDLTE网络前期规划就显得尤为重要，其中，关键点就是找准数据业务热点，实现有效分流。数据业务密度图是分析现网数据业务分布情况，从而确定TD—LTE覆盖区域的有效手段。本文结合TD—LTE扩大规模试验网天津工程的相关情况具体阐述生成方法和在网络规划中的应用。

Method of data service density diagram generation and its application in TD-LTE network planning

With the development of TD-LTE, China Mobile Communications Corporation of the accelerated pace of TD-LTE network planning has become a priority. TD-LTE network targeted at high-speed data services, for the relief of the pressing problems of the GSM network data traffic load is too high, and differs from the GSM network and TD-SCDMA network, TD-LTE, the same frequency network decided the optimizations of TD-LTE network limited means, so TD-LTE network pre-planning is particularly important. In which the key point is to identify the hot data services and achieve effective triage. Data traffic density map to analyze the distribution of the data services of the current network situation, so as to determine an effective means of TD-LTE coverage area. In this paper, TD-LTE to expand the scale test Tianjin specific elaborated method of generating and network planning.
