8.5.67 Measurements logging for ANR

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

When in idle mode, CELL_PCH, URA_PCH state or CELL_FACH state when second DRX cycle is used and Logged Measurements for ANR has been configured, the UE shall:

1> Store the available measurements according to the logged measurements configuration in variable LOG_ANR_CONFIG as specified in subclause 8.5.67.2.

8.5.67.1 General

This procedure specifies the logging of available measurements by a UE in idle mode, CELL_PCH, URA_PCH state or CELL_FACH state when second DRX cycle is used that has logged measurements configuration.

8.5.67.2 Initiation

While T327 is running, the UE shall:

1> perform the ANR measurements and evaluation on UTRAN, E-UTRAN or GERAN cells in accordance with the following:

2> if IE "Intra-UTRA ANR" is included in variable LOG_ANR_CONFIG:

3> if the UE camps normally on an UTRA cell (serving) that is part of the PLMN which is the same as one of the PLMNs in the IE "PLMN Identity" or IE "Equivalent PLMN Identity List" stored in variable LOG_ANR_REPORT_VARIABLE; and

3> if the serving cell and UTRA cell, not included in the neighbour cell list, together have not earlier been stored by UE in an entry of "Logged ANR Report Info" in the LOG_ANR_REPORT_VARIABLE; and

3> if the quality of the UTRA cell, not included in the neighbour cell list, exceeds the quality of the serving cell with more than the value of "Logging Relative Threshold", if this IE is present in the Logging Measurement Configuration message; and

3> if the quality of UTRA cell, not included in the neighbour cell list, is above the value of "Absolute Threshold"; and

3> if both the camping UTRAN cell and UTRA cell, not included in the neighbour cell list, are not CSG cells:

4> log the ANR information into the variable LOG_ANR_REPORT_VARIABLE as follows:

5> set the IEs "Serving PLMN Identity" to indicate the IE "PLMN Identity" included in MIB and "Serving Cell" to indicate cell identity of the cell the UE is camping on;

5> try to acquire the corresponding system information of the UTRA cell and set to the variable LOG_ANR_REPORT_VARIABLE as follows:

6> set the IE "Cell Identity" to indicate cell identity of this UTRA cell;

6> set the IE "PLMN Identity" to indicate the IE "PLMN Identity" included in MIB of this UTRA cell;

6> set the IE "UARFCN" and "Cell parameter ID" for a TDD cell or "Primary Scrambling Code" for a FDD cell.

2> if IE "Inter-RAT ANR for E-UTRA Indicator" is included in variable LOG_ANR_CONFIG:

3> if the UE reselected from a E-UTRA cell to an UTRA cell (serving cell) that is part of the PLMN which is the same as one of the PLMNs in the IE "PLMN Identity" or IE "Equivalent PLMN Identity List" stored in variable LOG_ANR_REPORT_VARIABLE; and

3> if the previously camped E-UTRAN cell is not included in the exclude-list for the EUTRAN frequency in SIB19 of the serving cell; and

3> if both the previously camped E-UTRAN cell and serving cell are not CSG cells; and

3> if the serving cell and E-UTRAN cell together have not earlier been stored by UE in an entry of "Logged ANR Report Info" in the LOG_ANR_REPORT_VARIABLE:

4> log the ANR information into the variable LOG_ANR_REPORT_VARIABLE as follows:

5> set the IEs "Serving PLMN Identity" to indicate the IE "PLMN Identity" included in MIB and "Serving Cell" to indicate cell identity of the serving cell;

5> set the IE "Cell Identity" to indicate cell identity of this previously camped E-UTRAN cell;

5> set the IE "PLMN Identity" to indicate the Primary PLMN which this previously camped E-UTRAN cell belongs to;

5> set the IE "Tracking Area Code" to indicate the TAC which this previously camped E-UTRAN cell belongs to;

5> set the IE "EARFCN" and the IE "EARFCN extension" when applicable and "Physical Cell Identity" of this previously camped E-UTRAN cell.

2> if IE "Inter-RAT ANR for GSM Indicator" is included in variable LOG_ANR_CONFIG:

3> if the UE reselected from a GSM cell to an UTRA cell (serving cell) that is part of the PLMN which is the same as one of the PLMNs in the IE "PLMN Identity" or IE "Equivalent PLMN Identity List" stored in variable LOG_ANR_REPORT_VARIABLE; and

3> if the previously camped GSM cell is not included in the neighbour cell list in SIB11/11bis/12 of the serving cell; and

3> if the serving cell is not a CSG cell; and

3> if the serving cell and GSM cell, not included in the neighbour cell list, together have not earlier been stored by UE in an entry of "Logged ANR Report Info" in the LOG_ANR_REPORT_VARIABLE:

4> log the ANR information into the variable LOG_ANR_REPORT_VARIABLE, as follows:

5> set the IEs "Serving PLMN Identity" to indicate the IE "PLMN Identity" included in MIB and "Serving Cell" to indicate cell identity of the serving cell;

5> set the IE "PLMN Identity", "Cell Identity" and "LAC" to indicate global cell identity of this previously camped GSM set cell;

5> set the IE "BSIC", "BCCH ARFCN" and "Band Indicator" of this previously camped GSM set cell.

2> when maximum number of entries for the ANR logging is reached, stop timer T327 and perform the same actions as upon expiry of T327, as specified in 8.5.63.5.
