What is use of PCO under PDN connectivity request?
Need to know is it mandatory to send.
Hi @ankgitm, please check this video:
This will help to understand PCO role.
Any quick explanation, layman language?
It’s in default IMS EPS bearer to further proceed for registration for SIP signalling.
Is it not used for LTE network without VoLTE?
Not it’s for VoLET IMS bearer attach.
In my view I find it in LTE network as well.
If you have, get IMS APN with LTE APN in PDN connectivity.
It is used to get the IP of which p-cscf UE need to connect through PDN.
Indeed, p-cscf for VoLTE and DNS IP for LTE.
