LTE L13A - Signal Loss

[dadoba]

Hello guys,

In your E/// LTE networks somebody are facing sudden loss of LTE signal? Let me clarify, we have at this moment L13A running in our LTE network and in a LTE good coverage sometimes the UE loss signal and goes to emergency calls mode some seconds after that UE attach to the LTE network again and sometimes attach in 3G network, remember LTE RF conditions are very good.

We are thinking that's not a radio problem cause not happens to all UEs at the same time and all KPIs are fine. Does anyboby have a tip about it? Does anybody is facing this same problem?
