The UE will not indicate the availability of MDT measurements in another RAT or in a PLMN that is not in the MDT PLMN list.

The network may decide to retrieve the logged measurements based on this indication. In case Logged MDT measurements are retrieved before the completion of the pre-defined logging duration, the reported measurement results are deleted, but MDT measurement logging will continue according to ongoing logged measurement configuration.

In case the network does not retrieve Logged MDT measurements, UE should store non-retrieved measurements for 48 hours from the moment the duration timer for logging expired. There is no requirement to store non-retrieved data beyond 48 hours. In addition, all logged measurement configuration and the log shall be removed by the UE at switch off or detach.

The UE may:

1> maintain a list of the set of cells to which the UE has Radio Links if the IE "Cell ID" is present.

[TS 37.320, clause 5.1.1.3.1 (TP2)]

The UE will not indicate the availability of MDT measurements in another RAT or in a PLMN that is not in the MDT PLMN list.

Reference

TS 25.304 clause 5.7, TS 25.331 clauses 8.5.65.2, 8.5.64.3 and TS37.320 clause 5.1.1.3.1.

8.6.3.4.3 Test Purpose

1. Verify indication of availability of Logged MDT measurements in HANDOVER TO UTRAN COMMAND message.

2. Verify that logged measurement configurations and logs are maintained despite periods of interruptions due to UE transitions to other RAT.

8.6.3.4.4 Method of test

Parameter	Unit	T0	T1	T2
UTRA RF Channel Number		Mid Range Test Frequency
CPICH Ec(FDD)	dBm/3.84MHz	-60	-80	-60
PCCPCH_RSCP (TDD)	dBm	-60	-80	-60

Table 8.6.3.4-1 and table 8.6.3.4-2 illustrate the downlink power to be applied for the 2 cells at various time instants of the test execution. Columns marked "T0" denote the initial conditions, while column marked “T1” and “T2” is to be applied subsequently. The exact instants on which these values shall be applied are described in the texts in this clause.

The UE is in CELL_DCH state of cell 1.

SS transmits a LOGGING MEASUREMENT CONFIGURATION message to the UE to configure logged measurements.

SS disconnects the CS call.

SS transmits an RRC CONNECTION RELEASE message to the UE to disconnect the connection.

The UE transmits an RRC CONNECTION RELEASE COMPLETE message using unacknowledged mode.

Wait 10s to allow UE to activate logging.

The SS configures its downlink transmission power settings according to columns "T1" in tables’ 8.6.3.4-1 and 8.6.3.4-2. The UE performs cell re-selection to Cell 9 and performs location update.

UE triggers an MO call and enters U10 call active state.

The SS configures its downlink transmission power settings according to columns "T2" in tables’ 8.6.3.4-1 and 8.6.3.4-2.

The SS sends a MEASUREMENT INFORMATION to trigger the MS to perform measurements on the UTRAN cell.

The UE sends a MEASUREMENT REPORT to SS.

The SS sends INTERSYSTEM TO UTRAN HANDOVER COMMAND indicating the dedicated channel of the target cell to the MS through the GSM serving cell.

The UE handover to UTRAN cell from GERAN cell, and send HANDOVER TO UTRAN COMMAND message.

SS transmits a UE INFORMATION REQUEST message, and the IE "Logged Measurements Report Request" is present.

The UE shall transmit a UE INFORMATION REPONSE message, with IE "Logged Measurement Info-FDD" or "Logged Measurement Info-TDD".
