42.4.1.4 Network Control measurement reporting / Uplink transfer / Continuation in Idle mode.

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

42.4.1.4.1 Conformance requirement

The procedure for NC measurement report sending shall be initiated by the mobile station at the expiry of the NC measurement report interval timer T3158. At expiry of the timer T3158 the mobile station shall restart the timer T3158, perform the measurements and send the PACKET MEASUREMENT REPORT message containing the ‘NC measurement report struct’ on PACCH.

A set of measurement reporting parameters (NETWORK_CONTROL_ORDER and NC_REPORTING_PERIOD(s)) is broadcast on PBCCH. The parameters may also be sent individually to an MS on PCCCH or PACCH, in which case it overrides the broadcast parameters. The individual parameters are valid until the RESET command is sent to the MS or there is a downlink signalling failure or the MS goes to the Standby state.

42.4.1.4.2 Test Purpose

To verify that if the NC parameters are changed while in packet transfer mode, the MS continues to use the changed parameters after returning to packet idle mode.

Initial conditions

System Simulator:

1 cell, GPRS supported.

Test procedure

MS is brought into uplink packet transfer mode. SS commands MS to NC2 with PACKET MEASUREMENT ORDER. SS checks that the MS is sending the PACKET MEASUREMENT REPORT at the expiry of the reporting period. SS allows the MS to complete the data transfer. SS checks that after entering packet idle mode MS continues being in NC2 mode by receiving the PACKET MEASUREMENT REPORT.

The test is repeated twice for k=1, and k=2.

K=1:

READY TIMER is set to 2 min, NC_REPORTING_PERIOD_I set to 61.44 sec and NC_REPORTING_PERIOD_T set to 1.92 sec.

K=2:

READY TIMER is set to 30 sec, NC_REPORTING_PERIOD_I set to 7.68 sec and NC_REPORTING_PERIOD_T set to 1.92 sec.

CHANNEL REQUEST

‘Single block packet access’

For Rel4 and earlier MS: SS verifies that either Rel5 requirements are fulfilled OR: CHANNEL REQUEST arrives :

  • After NC_REPORTING_PERIOD_T from last execution of step 4b for first CHANNEL REQUEST.
    Note: When the MS enters Idle mode, the Channel Request may be delayed by one Paging block of the MS.
  • After NC_REPORTING_PERIOD_I from last CHANNEL REQUESTs (step 8) for following CHANNEL REQUEST(s).

For Rel5 and later MS: SS verifies that CHANNEL REQUEST arrives :

  • After NC_REPORTING_PERIOD_I from step 7

After NC_REPORTING_PERIOD_I from last CHANNEL REQUEST (step 8) for following CHANNEL REQUEST(s).

42.4.1.5.1 Conformance requirement

The procedure for NC measurement report sending shall be initiated by the mobile station at the expiry of the NC measurement report interval timer T3158. At expiry of the timer T3158 the mobile station shall restart the timer T3158, perform the measurements and send the PACKET MEASUREMENT REPORT message containing the ‘NC measurement report struct’ on PACCH.

A set of measurement reporting parameters (NETWORK_CONTROL_ORDER, NC_REPORTING_PERIOD(s) and optionally REPORT_TYPE, MULTIBAND_REPORTING, SERVING_BAND_REPORTING, XXX_MULTIRAT_REPORTING, XXX_REPORTING_OFFSET, XXX_REPORTING_THRESHOLD (XXX indicates frequency band or radio access technologies), FDD_REPORTING_THRESHOLD_2, REP_PRIORITY, REPORTING_RATE, INVALID_BSIC_REPORTING, SCALE_ORD, FDD_REP_QUANT, Qsearch_P, 3G_SEARCH_PRIO), E-UTRAN_REP_QUANT, E-UTRAN_FDD_REPORTING_THRESHOLD, E-UTRAN_FDD_REPORTING_THRESHOLD_2, E-UTRAN_TDD_REPORTING_THRESHOLD, E-UTRAN_TDD_REPORTING_THRESHOLD_2, E-UTRAN_FDD_MEASUREMENT_REPORT_OFFSET and E-UTRAN_TDD_MEASUREMENT_REPORT_OFFSET, Qsearch_P_E-UTRAN) is broadcast on BCCH and, excepting E-UTRAN parameters, on PBCCH if it exists.

The MS shall send measurement reports to the network as defined in subclause 10.1.4.1.
The MS shall only perform autonomous cell re-selection when the reselection is triggered by a downlink signalling failure as defined in subclause 6.5 or a random access failure as defined in 3GPP TS 44.018 and 3GPP TS 44.060 or if the cell is barred or the C1 criterion falls below zero. The MS shall only determine whether the cell is barred once camped on the cell.

Test procedure

MS is in packet idle mode in cell A (Carrier 1). MS sends a CHANNEL REQUEST for the measurement report. SS assigns resources for it. MS sends a PACKET MEASUREMENT REPORT. SS receives one more PACKET MEASUREMENT REPORT by repeating the above steps. SS starts sending the corrupted blocks on the MS PCH channel in such a way that DSC < 0. SS checks that the MS does reselection to cell B.

Maximum duration of the test
