Question on MME [CLOSED]

+1 vote
91 views

MME just stores the QOS info for each bearer.

During the srvcc, how does it determine that a particular bearer is CS or PS ? (I think it is with QCI, as voice has a QCI=1)

Any info /pointers regarding this will be very helpful.

Thanks a lot Salil. So is it safe to assume that all bearers except QCI=1 are PS.
Should be safe to assume, QCI 7 can also represent the voice but that is Non-GBR so should be treated PS.
Thanks a lot for the clarification.

An UE is registered in roaming in LTE network in combined registration (in both MME and VLR).
When the UE returns to its home network in 3G network, does the home network generate both MAP-CANCEL (to the previous VLR) and CLR (to the previous MME)?
Is it implementation dependent in the Home network? (HLR & HSS)
If only MAP-CANCEL is generated, when the MME will remove the IMSI records from its internal database?
