| Abstract: | Based on driving test data from several key cities,the influence on MOS of GSM voice services by voice codec mode,carrier frequency,RxQual,C/I and handover is analyzed.The relationships between MOS of WCDMA voice services and Ec/Io,the HSDPA download speed and CQI are also provided.Finally,suggestions on network optimization are given in view of the problems arising from statistical analysis. |
