PS TO CS message over the Sv interface is supposed to carry the info regarding the Voice bearer.
But from the contents of it, I don't see anywhere this info is sent in this message.
I am looking this from the MME perspective.
From the spec and our legacy untested code , i see that following fields are present.
2) MME Sv Address for Control Plane
3) MME Sv TEID for Control Plane
6) MM Context/ MME UE context
7) Source to Target Transparent Container
I am clear about the fields upto 5). Also the ENodeB sends the 7) Source to Target Transparent Container to MME. and MME simply transparently sends in the PS2CSRequest. But what about the 6).
Any sample message is also very helpful.
