LTE user-perceptive quality mainly includes two aspects, data rate and voice. Based on the theoretical analysis and test re-sults, it analyzes the influence on the data rate, such as overlapping coverage, PCI Mod3 interference, LTE/3G PS inter-opera-tion, etc. At the same time, it analyzes the key factors affecting LTE voice CSFB delay and return LTE network performance when voice is over. Furthermore, it presents the relevant optimization suggestions.
