In NSA configuration, during data traffic, initially it is splitted on NR and LTE. When VoLTE call starts, data traffic continues only on LTE and after the call it comes back on EN-DC.
Now the question: if there is any carrier aggregation in LTE, this is present during both VoLTE call and after call?
In my network I can see CA is released during the call and throughput decreases so much!
What is the right behavior?
