Scenario 1 when UE is not latching on source eNB or target eNB .
Source eNB starts tcrelocoverall timer after getting ho command so in this case source eNB will no get any UE context release from MME before t relocoverall then after t relocoverall expiry source eNB should release the UE context and should send UE context release to mme. MME also release the UE context and should send UE context release to target eNB . then target eNB shall release the UE context.

In second scenario if UE latching to source eNB before expiry of t relocoverall then UE continue with source eNB and source eNB shall send ho cancel to mme. Then MME shall send UE context release to target eNB .
