I was looking into IEs of handover required and handover command messages defined in 36.413 specification.
Sending "handover type" in handover required message towards the MME make sense but again get back the same IE in handover command message from MME in the handover command message, I could not make out the reason behind it.
Can someone please explain the reason of presence of "Handover Type" IE in the handover command message when eNodeB already knows which type of request it sent to MME for an UE ?
Is there any possibility MME can change the type of Handover in handover command message ? If yes then what could be the scenarios ?
