|
|
|
1. X2 setup process is performed between the two eNBs
|
|
|
|
1. Both eNBs are connected to the same EPC that supports the path switch required for X2 HO
|
|
|
|
1. UE measures the source/target cell’s signal quality based on the different cell IDs
|
|
|
|
1. UE is initially attached to eNB 0 and its mobility is emulated using an attenuator (real mobility can also be used) allowing the UE to handover from eNB0 to eNB1 that causes the related X2 HO signalling to be triggered as a consequence of the A3 event

1. Handover decision performed by source eNB (based on RSRP criteria-A3 event is supported) and then the X2 Handover Request is sent to the target eNB

1. X2 Handover Request ack is sent back from target eNb to source eNB

1. Path switch request is sent by target eNB to the MME

**Note 1: For the moment, OAI CN does not yet support the path switch message required for X2 HO, so to test you need to use a 3rd party EPC**
