Research on Wireless Key Techniques of VoLTE
摘要
Abstract
The research of VoLTE mainly focuses on the coverage, quality, capacity and new wireless techniques of voice coverage. For voice coverage, the maximal coverage capability and performance in existing TD-LTE networks were analyzed and veriifed by using link budget and trial results. For voice quality, the network trial results show that the MOS of VoLTE is signiifcantly outperformed than GSM. For capacity, the maximal number of concurrent users and the limited channels were presented under different conifgurations by means of theoretical analysis, which will provide the research direction on capacity enhancement. For new wireless techniques, principles and trial results of multi-bearer, RoHC, C-DRX, SPS, RoHC and TTI-Bundling were introduced.关键词
