11.2.9 Packet Measurement Report
04.603GPPGeneral Packet Radio Service (GPRS)Mobile Station (MS) - Base Station System (BSS) interfaceRadio Link Control / Medium Access Control (RLC/MAC) protocolRelease 1999TS
This message is sent on the PACCH from the mobile station to the network to report measurement results. The message may contain measurement results from the Network Control measurements or from the Extended measurements, but not both simultaneously. More than one message may be required depending on the number of measurements to report. For a (3G) multi-RAT mobile station, report on 3G cells may be included as a result of Network Control measurements.
Message type: PACKET MEASUREMENT REPORT
Direction: mobile station to network

Table 11.2.9.2: PACKET MEASUREMENT REPORT information element details
TLLI (32 bit field) |
PSI5_CHANGE_MARK (2 bit field) |
BA_USED (1 bit field) In case of NC measurement report, these fields shall be included and contain the value of the BA_IND, 3G_BA_IND and PSI3_CHANGE_MARK respectively in the messages defining the used Neighbour Cell list. In case PBCCH exists, PSI3_CHANGE_MARK shall be used. |
PMO_USED (1 bit field) |
NC_MODE (1 bit field) 0 Mobile station in mode NC1 |
RXLEV_SERVING_CELL (6 bit field) |
INTERFERENCE_SERVING_CELL (6 bit field) |
EXT_REPORTING_TYPE (2 bit field) bit |
I_LEVEL_TN0 (6 bit field) |
FREQUENCY_N (6 bit field) NC Measurements If PBCCH is allocated in the cell, the resulting frequency/cell list for NC Measurements is the GSM Neighbour Cell list defined in sub-clause 5.6.3.2. If PBCCH is not allocated in the cell, the resulting frequency/cell list for NC Measurements is – The BA(GPRS) (defined in sub-clause 5.6.3.2) before the MS has acquired the complete GSM Neighbour Cell list from the BCCH messages. In this case, the MS shall not include R99 extension (‘Additions in release 99’) in the PACKET MEASUREMENT REPORT message. – The GSM Neighbour Cell list (defined in sub-clause 5.6.3.2) after the MS has acquired the complete GSM Neighbour Cell list from the BCCH messages. EXT Measurements The ‘EXT Measurements Parameters’ can be repeated either in a sequence of PSI5 message instances or in a sequence of Packet Measurement Order message instances where each message instance can contain one or more sub-lists of frequency (ARFCN) parameters. The sub-lists of either of the messages shall then be concatenated into a resulting frequency list in order of appearance within a message instance and then in order of ascending message instances. Each added frequency position in the resulting frequency list shall then be assigned an ascending index used for measurement reports. If the same frequency is defined more than once in the resulting list, each occurrence will get en index, but measurements shall only be performed and reported for the last added position. For EXT measurements the FREQUENCY_N = 0 refers to the first frequency within the first message instance and FREQUENCY_N = n refers to the last frequency in the ‘EXT Frequency list struct’ within the last message instance. |
