We experience some issues with poor VoLTE quality , verified via KPIs and customer complaints in cells with very high number of UL active users(not VoLTE but total users). UL packet loss for QCI 1 is going up during congested hours . Any ideas how to alleviate the issue?
We have activated RoHC and TTI bundling. Will Semi persistent scheduling improve the situation?
Any other ideas?
Thanks for your input in advance
