– the UE is camped on a cell belonging to Area Configuration (see TS 25.331 [4]), if configured;

– the UE is camped on the RAT where the logged measurement configuration was received.

Otherwise, the logging of measurement results shall be suspended.

NOTE: Even if logging of measurement results is suspended, the logging duration timer and time stamp will continue, and the logged measurement configuration and corresponding log are kept.

[TS 25.331, clause 8.1.3.6 (TP3)]

This test is applicable for all UEs that support Logged MDT services.

8.6.2.4a.2 Conformance requirement

[TS 25.304, clause 5.7 (TP1, TP2)]

If the configuration of logged measurements is valid, the UE shall perform logging of measurement results if all of the following conditions are met:

– the UE is in camped normally state in idle mode, CELL_PCH or URA_PCH state;

– the UE is camped on a cell belonging to Area Configuration (see TS 25.331 [4]), if configured;

– the UE is camped on the RAT where the logged measurement configuration was received.

Otherwise, the logging of measurement results shall be suspended.

NOTE: Even if logging of measurement results is suspended, the logging duration timer and time stamp will continue, and the logged measurement configuration and corresponding log are kept.

[TS 25.331, clause 8.5.65.2 (TP1, TP2)]

While T326 is running, the UE shall:

1> perform this logging in accordance with the following:

2> perform the logging while camping normally on an UTRA cell and the RPLMN of the UE is present in the "PLMN Identity List" stored in LOGGED_MEAS_REPORT_VARIABLE and, if the IE "Area Configuration" is present in variable LOGGED_MEAS_CONFIG, that is part of the concerned area;

2> perform the logging at regular intervals, as defined by the IE "Logging Interval” in variable LOGGED_MEAS_CONFIG;

2> when adding a logged measurement entry in variable LOGGED_MEAS_REPORT_VARIABLE, include the fields in accordance with the following:

3> set the IE "Relative Time Stamp" to indicate time relative to the moment at which the logged measurement configuration was received;

3> if GNSS location information became available during the last logging interval:

4> if the UE has been able to calculate a 3-dimensional position:

5> set IE "Ellipsoid point with altitude" or the IE "Ellipsoid point with altitude and uncertainty ellipsoid" to include the location coordinates;

4>else:

5> set IE "Ellipsoid point" or the IE "Ellipsoid point with uncertainty circle" or the IE "Ellipsoid point with uncertainty ellipse" to include the location coordinates:

4> a value of the IE "Confidence", different from "0" should be calculated, as the probability that the UE is located within the uncertainty region of the one of the IEs "Ellipsoid point with uncertainty ellipse" or "Ellipsoid point with altitude and uncertainty ellipsoid".

3> set the IE "PLMN Identity" of the Logged Measurements Serving Cell to indicate the PLMN Identity of the cell the UE is camping on obtained from system information;

3> set the IE "Cell ID" to indicate cell identity of the cell the UE is camping on obtained from system information;

3> set the IE "CPICH Ec/N0" and "CPICH RSCP" to include measured quantities of the cell that the UE is camping on for UTRA FDD;

3> set the "P-CCPCH RSCP" to include measured quantities for the cell that the UE is camping on for UTRA 1.28 Mcps TDD;

3> set the IE "Logged Measurements Intra Frequency Neighbouring Cells list", "Logged Measurements Inter Frequency list", "Logged Measurements E-UTRA frequency list", "Logged Measurements E-UTRA frequency extension list", in order of decreasing ranking quantity as used for cell re-selection in each frequency for at most the following number of neighbouring cells; 6 intra-frequency and 3 inter-frequency neighbours per frequency as well as 3 inter-RAT neighbours, per frequency per RAT;

3> set the IE "Logged Measurements GSM Neighbouring Cells list" in order of decreasing RXLEV.
