By stable I mainly meant a UE can attach and be used for hours without losing connection or things crashing.
When we do this, we may run one or two speed tests, but mostly just use the UE for work, email, web browsing, etc.
We have connected and disconnected a handful of times in a single boot of processes. Some portion of these fail, I haven't been tracking an exact count. Once it fails, we have to bounce the MME and eNB processes.
Current best guess is a bad state gets stuck somewhere in the MME. We are looking into it. If we find anything we'll contribute to the project.
We are trying 10MHz this week. Got a little distracted there once things "worked" for a little.
We will not be trying handovers. I was not under the impression that worked. Do you mean X2 or S10 handovers?
