3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
42.4.6.1 Network Control PEMR – Activation with SI Messages
42.4.6.1.1 Conformance requirement
1 The behaviour of the mobile station is controlled by the parameter NETWORK_CONTROL_ORDER broadcast in the PSI5 message on PBCCH, in the SI13 and SI2quater messages on the BCCH and in the PSI13 message on PACCH.
When in mode NC1 or NC2, the mobile station shall perform the NC measurements as defined in 3GPP TS 05.08. The reporting periods are indicated in the NC_REPORTING_PERIOD_I and NC_REPORTING_PERIOD_T field of the PSI5, the SI2quater, the PACKET CELL CHANGE ORDER or the PACKET MEASUREMENT ORDER message
On expiry of timer T3158, the mobile station shall restart timer T3158 with the indicated reporting period, perform the measurements and send either the PACKET MEASUREMENT REPORT message or the PACKET ENHANCED MEASUREMENT REPORT to the network. The condition for sending the PACKET ENHANCED MEASUREMENT REPORT message instead of the PACKET MEASUREMENT REPORT message is based on the REPORT_TYPE parameter and if the MS has received BSIC information for all cells.
2 In packet idle mode, the reporting period is NC_REPORTING_PERIOD_I rounded off to the nearest smaller integer multiple of DRX period if NC_REPORTING PERIOD_I is greater than DRX period, else, the reporting period is DRX period

Test procedure
MS is powered on and Attach procedure is completed. The negotiated Ready Timer value in ATTACH ACCEPT indicates the ready timer function is active for 60 seconds. When the measurement reporting time becomes valid, the MS sends a CHANNEL REQUEST message indicating ‘Single block packet access’ on RACH. The network shall then respond with an IMMEDIATE ASSIGNMENT message granting a ‘single block access’ on a PDCH. The mobile station shall then send the PACKET ENHANCED MEASUREMENT REPORT message in the allocated radio block on the assigned PDCH as indicated in the Measurement Parameters struct.

The procedure for NC measurement report sending shall be initiated by the mobile station at 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 either the PACKET MEASUREMENT REPORT message containing the ‘NC measurement report struct’ or the PACKET ENHANCED MEASUREMENT REPORT on PACCH.

The behaviour of the mobile station is controlled by the parameter NETWORK_CONTROL_ORDER broadcast in the PSI5 message on PBCCH, in the SI13 and SI2quater messages on the BCCH and in the PSI13 message on PACCH. Alternatively, the network may send the NETWORK_CONTROL_ORDER parameters in a PACKET MEASUREMENT ORDER or in a PACKET CELL CHANGE ORDER message on PCCCH or PACCH to a particular mobile station.
When in mode NC1 or NC2, the mobile station shall perform the NC measurements as defined in 3GPP TS 05.08. The reporting periods are indicated in the NC_REPORTING_PERIOD_I and NC_REPORTING_PERIOD_T field of the PSI5, the SI2quater, the PACKET CELL CHANGE ORDER or the PACKET MEASUREMENT ORDER message
The procedure for NC measurement report sending shall be initiated by the mobile station at 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 either the PACKET MEASUREMENT REPORT message containing the ‘NC measurement report struct’ or the PACKET ENHANCED MEASUREMENT REPORT on PACCH.
Following a downlink TBF establishment, the PACKET MEASUREMENT REPORT or PACKET ENHANCED MEASUREMENT REPORT message shall not be sent on the uplink PACCH associated with this TBF until two PACKET DOWNLINK ACK/NACK messages has been sent to the network.

42.4.6.6 Network Control PEMR / Packet Cell Change Order
42.4.6.6.1 Conformance requirement
For (NC) measurement reporting, the Mobile Station shall use PACKET ENHANCED MEASUREMENT REPORT messages instead of PACKET MEASUREMENT REPORT messages if that is indicated by the parameter REPORT_TYPE and if at least one BSIC is allocated to each frequency in the BA(GPRS) list.
Reference:
3GPP TS 04.60 / 3GPP TS 44.060 5.6.1
42.4.6.6.2 Test purpose
To verify that the MS sends PEMR following the report type specified in Packet Cell Change Order.

System simulator:
2 GPRS cells A and B SI2quater includes GPRS MEASUREMENT PARAMETERS description. In both cells Network Control Order is NC2 and PMR shall be used.

Test procedure
MS is brought into downlink transfer mode. SS sends data blocks and MS answers with PACKET DOWNLINK ACK/NACK until at least one PACKET MEASUREMENT REPORT has been received.
SS sends then a PACKET CELL CHANGE ORDER message to MS ordering the MS to select Cell-B and to use NC2 and PEMR.
The MS performs a cell update.
MS is brought into downlink transfer mode. SS sends data blocks and MS answers with PACKET DOWNLINK ACK/NACK until at least one PACKET ENHANCED MEASUREMENT REPORT has been received.
