Analysis of LTE traffic offloading based on big data

There are more inter-RAT (Radio Access Technology) operations between LTE network and GSM/UMTS networks at the early stage of the LTE network construction due to the insufficient LTE signal coverage. The proportion of camping on LTE network impacts customer ratings and revenue of mobile operators. In this paper, a new KPI (Key Performance Indicator) related to LTE camping rate was defined based on the data of BOSS (Business & Operation Support System) and OMC (Operation & Maintenance Center) from the Big Data Platform of Shanghai Unicom, and the scenarios or areas with low LTE camping rate were identified through a multi-indicator analysis and geographic display. Therefore, we can determine the priorities of construction and optimization in order to enhance user experiences.
