Is QoS has really been implemented in LTE commercial networks?

Question

I am wandering to check if QoS has really been implemented in LTE commercial networks. If yes,

i) Is this limited to VoLTE, or are there other application specific scenarios as well?
ii) Are operators already using extended QCIs in commercial networks?

Commercial deployment and application references will be highly appreciated?

Comments

I was in the impression that QoS must has been implemented in the commercial network but could not find any reference and any mention of it so  can't say anything about it...

Check if the following document is useful http://www.ixiacom.com/pdfs/library/white_papers/policy_management.pdf

And wait for some more people to comment on it.

Short answer is not yet (AFAIK) however many of the operator are very close t implement QoS and not just limited to VoLTE but to various other applications specially QCI 3 & 4.
Dont know about Extended QCI may be will ask a question to get the clarity of this topic.
