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)
This field contains the TLLI / G-RNTI of the mobile station. This field is encoded as defined in sub-clause 12.16.

NC_MODE (1 bit field)
This field indicates if the mobile station was in mode NC1 or NC2 when sending the measurement report.

0 Mobile station in mode NC1
1 Mobile station in mode NC2

BA_USED (1 bit field),
3G_BA_USED (1 bit field)
PSI3_CHANGE_MARK
(2 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.
In case PBCCH does not exist, BA_USED and 3G_BA_USED shall be used.

PMO_USED (1 bit field)
This parameter shall contain the value of the PMO_IND in the PACKET CELL CHANGE ORDER or PACKET MEASUREMENT ORDER messages that has modified the used Neighbour Cell list. If no such message has been received, PMO_USED shall be set to zero.

BSIC_Seen (1 bit field)
This parameters indicates if a GSM cell with invalid BSIC and allowed NCC part BSIC is one of the six strongest, see 3GPP TS 45.008.

Bit
0 No cell with invalid BSIC and allowed NCC part of BSIC is seen
1 One cell or more with invalid BSIC and allowed NCC part of BSIC is seen

SCALE (1 bit field)
The value of this field is defined in 3GPP TS 45.008.

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)
This field contains the value of the RXLEV parameter for the serving cell calculated by the mobile station (see 3GPP TS 45.008). This field is encoded as the binary representation of the RXLEV parameter value defined in 3GPP TS 45.008.
Range 0 to 63

Neighbour cell reporting

Repeated Invalid BSIC
This structure contains the report of cells with invalid BSIC.
BCCH-FREQ-NCELL (5 bits). This field represents the index of the BA(GPRS), see 3GPP TS 44.018.
BSIC (6 bits). Base station identity code of the corresponding index in the BA(GPRS).
RXLEV (6 bits). GSM reporting quantity, see 3GPP TS 45.008.

Bitmap type reporting:
This structure contains the report of cells with valid BSIC.
Each bit of the bitmap points to the corresponding index of the Neighbour Cell list defined in sub-clause 5.6.3.3 ("Deriving the Neighbour Cell list from the GSM Neighbour Cell list and the 3G Neighbour Cell list").

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):
Measurement quantities are defined in 3GPP TS 45.008.

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:
This structure contains the report of cells with valid BSIC.
Each bit of the bitmap points to the corresponding index of the Neighbour Cell list defined in sub-clause 5.6.3.3 ("Deriving the Neighbour Cell list from the GSM Neighbour Cell list and the 3G Neighbour Cell list").

REPORTING_QUANTITY (6 bits):
Measurement quantities are defined in 3GPP TS 45.008.

E-UTRAN Measurement Report
This information element contains the measurement reports for one or more E-UTRAN neighbour cell. This field is defined in sub-clause 11.2.9.

UTRAN CSG Measurement Report
Measurement reporting for UTRAN CSG cells is defined in 3GPP TS 45.008. This information element contains the measurement results and routing parameters for one UTRAN CSG or hybrid cell. It is defined in sub-clause 12.61.

E-UTRAN CSG Measurement Report
Measurement reporting for E-UTRAN CSG cells is defined in 3GPP TS 45.008. This information element contains the measurement results and routing parameters for one E-UTRAN CSG or hybrid cell. It is defined in sub-clause 12.60.

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.
