李品谊. Technological research on enhance voice perception of VoLTE users based on parameter optimization[J]. 2020, 33(1): 89-92. DOI: 10.13992/j.cnki.tetas.2020.01.019.
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.
