How can I findout if handover is X2 based or S1 based?

Question

In case of hub-and-spoke topology, X2 messaging can travel all the way back to an aggregation point, which may be co-located with EPC. In such scenario both X2 and S1 traverses same physical path (a.k.a X2 over S1). Please consider both Intra-MME and Inter-MME handover scenarios. Would X2 based handover in such a case yield advantage over S1 based handover. Thanks.

Answer 1

Who is I here will u specify which specific network entity ???

If u are thinking about UE how he will know whether it is going to be S1 Based or X2 Based , UE only want a new ENB info which we share in RRC Reconfig->Mobility control info so UE will not care about which type of handover happened for him.

In both handover the messages flow differs only in core network side only.
