Management based MDT: MDT data is collected from UEs in a specified area. The area is defined as a list of cells (UTRAN or E-UTRAN) or as a list of tracking/routing/location areas. The management based MDT is an enhancement of the management based trace functionality. Management based MDT can be either a logged MDT or Immediate MDT.

Immediate MDT: See 3GPP TS 37.320 [30]

Logged MDT: See 3GPP TS 37.320 [30]

Logged MBSFN MDT: Collection of MBSFN measurements in idle and connected mode. Applicable only for eUTRAN.

Signalling based MDT:MDT data is collected from one specific UE. The UE that is participating in the MDT data collection is specified as IMEI(SV) or as IMSI. The signalling based MDT is an enhancement of the signalling based subscriber and equipment trace. A signalling based MDT can be either a logged MDT or Immediate MDT.

MBSFN Area: See 3GPP TS 36.300 [37]

MBSFN Area Reserved Cell: See 3GPP TS 36.300 [37]
