11.2.9d Packet Enhanced Measurement Report
3GPP44.060General Packet Radio Service (GPRS)Mobile Station (MS) - Base Station System (BSS) interfaceRadio Link Control / Medium Access Control (RLC/MAC) protocolRelease 17TS
This message is sent either on the PACCH if in packet transfer mode or on an assigned block on a PDTCH, from the mobile station to the network to report enhanced measurement results. The message contains measurement results from the Network Control measurements.
Message type: PACKET ENHANCED MEASUREMENT REPORT
Direction: mobile station to network

Table 11.2.9d.2: PACKET ENHANCED MEASUREMENT REPORT information element details
TLLI / G-RNTI (32 bit field) |
NC_MODE (1 bit field) 0 Mobile station in mode NC1 |
BA_USED (1 bit field), These fields shall contain the value of the BA_IND, 3G_BA_IND and PSI3_CHANGE_MARK respectively in the messages defining the used Neighbour Cell list or E-UTRAN Neighbour Cell list. In case PBCCH exists, PSI3_CHANGE_MARK shall be used. |
PMO_USED (1 bit field) |
BSIC_Seen (1 bit field) Bit |
SCALE (1 bit field) |
Serving cell reporting If the structure "serving cell data" is missing, this indicates that no valid measurement exist for the serving cell. RXLEV_SERVING_CELL (6 bit field) |
Neighbour cell reporting Repeated Invalid BSIC Bitmap type reporting: If this structure is present and more bits than needed are available at the end of the message, the MS shall set the value of the redundant bitmap positions to ‘0’. At least 96 neighour cell entries shall be encoded in the bitmap. If this structure is present, some remaining bits indicating no report at the end of the message may be omitted if these bits do not fit into the message. This shall not lead to an error in the receiver of that message. If E-UTRAN neighbour cells are to be reported, then this structure shall be omitted and replaced by the bitmap reporting structure in the release-8 extension of this message. REPORTING_QUANTITY (6 bits): |
G-RNTI extension (4 bit field) This field contains the extra 4 bits of the G-RNTI not included in the TLLI / G-RNTI field which are necessary to provide a unique identifier in Iu mode. |
E-UTRAN Neighbour cell reporting BITMAP_LENGTH (7 bit field) 1+val(BITMAP_LENGTH) indicates the number of entries in the reporting bitmap. Bitmap type reporting: REPORTING_QUANTITY (6 bits): |
E-UTRAN Measurement Report |
UTRAN CSG Measurement Report |
E-UTRAN CSG Measurement Report |
SI23_BA_USED (1 bit field) This field contains the value of the SI 23_BA_IND field in the SYSTEM INFORMATION TYPE 23 message defining the E-UTRAN Neighbour Cell list used. In the case SYSTEM INFORMATION TYPE 23 message is not broadcast in the cell or if the mobile station does not support network sharing this field shall be set to 0. Range 0 to 1. |
