Surveying, if detected unsuccessfully, representing that UE uses complete guarantor and the AES of source RNC, then target eNodeB uses in second step
Complete guarantor and AES process safety detection that the UE that source station band comes uses in source eNodeB, detection is passed through, and UE is in target
The RRC of eNodeB side re-establishes successfully.
14th step：Target eNodeB sends RRC and reconfigures (CONNECTION RECONFIGURATION) message to UE,
The complete guarantor of target eNodeB and AES are allocated to UE.
15th step：UE receives after RRC reconfigures (CONNECTION RECONFIGURATION) message, receives new
Complete protect and AES configuration, and send RRC and connect and reconfigure (CONNECTION RECONFIGURATION COMPLETE) and arrive
Target eNodeB is stood, and so far UE and the follow-up message of target eNodeB use that Target Station is complete to protect algorithm and AES.
