Hi Experts,
Can we check any LTE SMS related KPI from OSS?

Is this SMS over NAS or SMS via IMS?
In former case, check MME documentation and in later case you should check IMS documentation.

Thanks. I think signaling indicates over NAS.
But will it use SGs as MME will route to MSC-S.

Anyone knows how to check SMS traffic in LTE or due to NAS/SGs we have to check from 3G end?
