This procedure enables an eNB to negotiate the handover trigger settings with a peer eNB controlling neighboring cells.

mobilitySettingsChange X2AP-ELEMENTARY-PROCEDURE ::= {
   INITIATING MESSAGE MobilityChangeRequest
   SUCCESSFUL OUTCOME MobilityChangeAcknowledge
   UNSUCCESSFUL OUTCOME MobilityChangeFailure
   PROCEDURE CODE id-mobilitySettingsChange
   CRITICALITY reject
}

MobilityChangeRequest ::= SEQUENCE {
   protocolIEs ProtocolIE-Container {{MobilityChangeRequest-IEs}},
   ...
}

MobilityChangeRequest-IEs X2AP-PROTOCOL-IES ::= {
   { ID id-ENB1-Cell-ID CRITICALITY reject TYPE ECGI PRESENCE mandatory }|
   { ID id-ENB2-Cell-ID CRITICALITY reject TYPE ECGI PRESENCE mandatory }|
   { ID id-ENB1-Mobility-Parameters CRITICALITY ignore TYPE MobilityParametersInformation PRESENCE optional }|
   { ID id-ENB2-Proposed-Mobility-Parameters CRITICALITY reject TYPE MobilityParametersInformation PRESENCE mandatory }|
   { ID id-Cause CRITICALITY reject TYPE Cause PRESENCE mandatory },
   ...
}

MobilityChangeAcknowledge ::= SEQUENCE {
   protocolIEs ProtocolIE-Container {{MobilityChangeAcknowledge-IEs}},
   ...
}

MobilityChangeAcknowledge-IEs X2AP-PROTOCOL-IES ::= {
   { ID id-ENB1-Cell-ID CRITICALITY reject TYPE ECGI PRESENCE mandatory }|
   { ID id-ENB2-Cell-ID CRITICALITY reject TYPE ECGI PRESENCE mandatory }|
   { ID id-CriticalityDiagnostics CRITICALITY ignore TYPE CriticalityDiagnostics PRESENCE optional },
   ...
}

MobilityChangeFailure ::= SEQUENCE {
   protocolIEs ProtocolIE-Container {{MobilityChangeFailure-IEs}},
   ...
}

MobilityChangeFailure-IEs X2AP-PROTOCOL-IES ::= {
   { ID id-ENB1-Cell-ID CRITICALITY ignore TYPE ECGI PRESENCE mandatory }|
   { ID id-ENB2-Cell-ID CRITICALITY ignore TYPE ECGI PRESENCE mandatory }|
   { ID id-Cause CRITICALITY ignore TYPE Cause PRESENCE mandatory }|
   { ID id-ENB2-Mobility-Parameters-Modification-Range CRITICALITY ignore TYPE MobilityParametersModificationRange PRESENCE optional }|
   { ID id-CriticalityDiagnostics CRITICALITY ignore TYPE CriticalityDiagnostics PRESENCE optional },
   ...
}
