Abstract

In the process of VoLTE network optimization

this essay mainly explores the methods of reducing the packet loss rate of VoLTE and increasing the value of MOS through the combination and adjustment of background parameters. In this essay

basing on the background parameters of some equipment

the parameters such as pdcchCfiMode

pdcchLaGinrMargin

dlMaxHARQTx/ulMaxHARQTx and tReorderingUl/tReorderingDl are adjusted to improve the degree of channel aggregation

increase the retransmission times of MAC layer HARQ

and increase the RLC layer sort wait timer. The obvious decrease of packet loss rate and the improvement of Mos value can be obtained

so as to improve the voice quality of VoLTE and optimize the VoLTE network efficiently. It can be widely promoted to improve the perception of VoLTE users.
