8.7.1 Inter-RAT / UTRAN ANR measurement, logging and reporting / E-UTRAN cell

8.7.1.1 Test Purpose (TP)

(1)

with { UE in UTRA CELL_DCH state }

ensure that {

when { UE receives a LOGGING MEASUREMENT CONFIGURATION message containing Logged ANR configuration Info with E-UTRA Indicator set to TRUE }

then { UE reads “Logged ANR configuration info” and configure UE to perform inter-RAT ANR measurements for E-UTRAN to be reported in the logged ANR report provided to the network in the UE INFORMATION RESPONSE message }

}

(2)

with { UE in E-UTRA RRC IDLE state and T327 timer is running }

ensure that {

when { UE performs cell reselection to a UTRAN cell belonging to the PLMN or the list of Equivalent PLMNs where the Logging Measurement Configuration was received and source E-UTRAN cell is not included in the blacklist for the E-UTRAN frequency in SIB 19 on target UTRAN cell }

then { UE performs inter-RAT ANR logging for the E-UTRAN cell to be reported in the logged ANR report provided to the network in the UE INFORMATION RESPONSE message }

}

(3)

with { UE in UTRA IDLE state and UE has a Inter-RAT ANR logging measurement stored for E-UTRAN cell and the registered PLMN is the same as the IE "PLMN Identity" stored in LOG_ANR_REPORT_VARIABLE }

ensure that {

when { receiving RRC CONNECTION SETUP message }

then { UE includes the ANR Logging Results Available IE in the RRC CONNETION SETUP COMPLETE message }

}

(4)

with { UE in UTRA CELL_DCH state and UE has inter-RAT ANR logging results available for E-UTRAN and the registered PLMN is the same as the IE "PLMN Identity" stored in variable LOG_ANR_REPORT_VARIABLE }

ensure that {

when { UE receives an UE INFORMATION REQUEST message with Logged ANR Report Request IE which is asking for ANR log from UE }

then { UE sends an UE INFORMATION RESPONSE message with ANR logged data for E-UTRAN }

}

8.7.1.2 Conformance requirements

References: The conformance requirements covered in the current TC is specified in: TS 25.304, clauses 5.8.2.2; TS 25.331, clauses 8.1.3.6, 8.5.63.3, 8.5.64.3 and 8.5.67.2

[TS 25.304, clause 5.8.2.2 (TP2)]

If configured to perform inter-RAT ANR via the Logging Measurement Configuration message, the UE may perform inter-RAT ANR logging only when:

– after inter-RAT cell reselection from E-UTRAN or GSM to a normal UTRAN cell belonging to the PLMN or the list of Equivalent PLMNs where the Logging Measurement Configuration is received.

During the inter-RAT ANR process, the UE may log the corresponding information of the previously camped E-UTRAN or GSM cell as specified in TS 25.331.

[TS 25.331, clause 7.2.1 (TP2)]

The UE shall perform ANR measurements and logging as specified in [4], when logged ANR measurement is configured.

[TS 25.331, clause 8.1.3.6 (TP3)]

The UE shall compare the value of the IE "Initial UE identity" in the received RRC CONNECTION SETUP message with the value of the variable INITIAL_UE_IDENTITY.

…

If the values are identical, the UE shall:

…

1> submit an RRC CONNECTION SETUP COMPLETE message to the lower layers on the uplink DCCH after successful state transition per subclause 8.6.3.3, with the contents set as specified below:

2> if an IE "Logged ANR Report Info" in variable LOG_ANR_REPORT_VARIABLE is present and the registered PLMN is the same as the IE "PLMN Identity" stored in variable LOG_ANR_REPORT_VARIABLE:

3> include IE "ANR Logging Results Available".

[TS 25.331, clause 8.5.63.3 (TP1)]

Upon receiving the LOGGING MEASUREMENT CONFIGURATION message the UE shall:

1> if IE "Logged ANR configuration Info" is present:

2> if variable LOG_ANR_CONFIG was already stored, discard the existing logged measurement configuration for ANR purpose as well as the associated logged measurement information as specified in 8.5.66;

2> store the received IEs in the IE "Logged ANR configuration Info" in variable LOG_ANR_CONFIG;

2> store the current Registered PLMN in the IE "PLMN Identity" in variable LOG_ANR_REPORT_VARIABLE;

2> start timer T327 with the timer value set to the IE "Logging Duration" included in IE "Logged ANR configuration Info".

[TS 25.331, clause 8.5.64.3 (TP4)]

The UE shall:

1> if IE "Logged ANR Report Request" is present:

2> if Registered PLMN is the same as the IE "PLMN Identity" stored in variable LOG_ANR_REPORT_VARIABLE:

3> if IE "Logged ANR Report Info" in variable LOG_ANR_REPORT_VARIABLE is present:

4> set IEs "Logged ANR Report Info" in the UE INFORMATION RESPONSE as follows:

5> include the IEs "Logged ANR Report Info List" and set it to include entries from LOG_ANR_REPORT_VARIABLE;

5> clear the logged measurement results included in the list of IEs "Logged ANR Report Info List" from the LOG_ANR_REPORT_VARIABLE;

5> clear the variable LOG_ANR_CONFIG and stop timer T327.

2> transmit a UE INFORMATION RESPONSE message on the uplink DCCH using AM RLC.

[TS 25.331, clause 8.5.67.2 (TP2,TP4)]

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 “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 PLMN as the IE “PLMN Identity” stored in variable LOG_ANR_REPORT_VARIABLE; and

3> if the previously camped E-UTRAN cell is not included in the blacklist 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:

4> log the ANR information into the variable LOG_ANR_REPORT_VARIABLE, if E-UTRA related ANR information has not been logged before, as follows:

5> set the IEs "Serving PLMN Identity" 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 "Physical Cell Identity" of this previously camped E-UTRAN cell.
