Mobility KPI in LTE

Mobility is defined as the product of the handover preparation success rate and the handover execution success rate.

The handover preparation success rate is derived by taking the number of successful handover preparations and dividing it by the number of attempts.

The handover preparation attempt is typically pegged when the source eNB sends either an X2 Handover Request message, or an S1 Handover Required message.

The source eNB reception of an X2 Handover Request Ack message, or an S1 Handover Command message, is considered a successful handover preparation.

The handover execution success rate is calculated in a similar manner by taking the number of successful handover executions and dividing it by the number of attempts.

The handover execution attempt is typically counted when the source eNB sends an RRC Connection Reconfiguration message to the UE which includes mobility control information.

The source eNodeB reception of either an X2 UE Context Release message, or an S1 UE Context Release Command message, is considered a successful handover preparation.
