Table 10.5.73/GSM 04.08

CBQ, CELL_BAR_QUALIFY (1 bit field)

CELL_BAR_QUALIFY is used by the network to control mobile station cell selection and reselection. The use andcoding of this parameter is defined in GSM 05.08.

CELL_RESELECT_OFFSET (6 bit field)

CELL_RESELECT_OFFSET is coded as the binary representation of the "CELL_RESELECT_OFFSET" inGSM 05.08. It is a value used by the mobile station to apply a positive or negative offset to the value of C2 as defined inGSM 03.22 and GSM 05.08.

TEMPORARY_OFFSET (3 bit field)

The TEMPORARY_OFFSET field is coded as the binary representation of the "TEMPORARY_OFFSET" inGSM 05.08. It is used by the mobile station as part of its calculation of C2 for the cell reselection process as describedin GSM 05.08. It is used to apply a negative offset to C2 for the duration of PENALTY_TIME.

PENALTY_TIME (5 bit field)

The PENALTY_TIME is coded as the binary representation of the "PENALTY_TIME" in GSM 05.08. It defines thelength of time for which TEMPORARY_OFFSET is active. The usage of PENALTY_TIME is described in GSM 03.22and GSM 05.08.

Table 10.5.74/GSM 04.08

POWER OFFSET (2 bit field)

POWER OFFSET is used only by DCS 1800 Class 3 MSs to add a power offset to the value ofMS_TXPWR_MAX_CCH used for its random access attempts. It is also used by the MS in its calculation of C1 and C2parameters. Its use is defined in GSM 05.08

If this parameter is transmitted on a BCCH carrier within the DCS 1800 band, its meaning shall be described below:

Value Meaning00 0 dB power offset01 2 dB power offset10 4 dB power offset11 6 dB power offset

If this parameter is transmitted on a BCCH carrier outside the DCS 1800 band, then all bit positions shall be treated asspare.

GPRS IndicatorThe GPRS Indicator contains the RA COLOUR field and the SI13_POSITION field. If the GPRS Indicator iscontained in the information element, it indicates that GPRS is supported in the cell.

RA COLOUR (3 bit field) If the mobile station receives different values of the RA COLOUR field in different cell, the mobile station shallinterpret the cell re-selection information as if the two cells belong to different routeing areas.

SI13_POSITION (1 bit field)The SI13 POSITION field indicates the minimum schedule for where the SYSTEM INFORMATION TYPE 13message is sent on BCCH, see GSM 05.02:

0 SYSTEM INFORMATION TYPE 13 message is sent on BCCH Norm;1 SYSTEM INFORMATION TYPE 13 message is sent on BCCH Ext.

Break IndicatorThe Break Indicator indicates if parameters in addition to those in SI 4 rest octets are sent in SI7 and SI8. 0 Additional parameters are not sent in SYSTEM INFORMATION TYPE 7 and 8. 1 Additional parameters, “SI4 Rest Octets_S” are sent in SYSTEM INFORMATION TYPE 7 and 8.

PRIO_THR (3 bit field)The PRIO_THR field is a signal threshold used by the mobile station to determine whether prioritised cell re-selection shall apply. The use and coding of this parameters is defined in GSM 05.08.

LSA_OFFSET (3 bit field)The LSA_OFFSET field applies an offset for LSA reselection between cells with same LSA priorities. The useand coding of this parameters is defined in GSM 05.08.

EXC_ACC (1 bit field)EXC_ACC is used by the network to prevent mobile stations from camping on the cell. The usage of EXC_ ACCis described in GSM 03.22. The coding is as follows:0 The cell is not used for SoLSA exclusive access.1 The cell is used for SoLSA exclusive access.

MCC (12 bit field)In addition to the EXC_ACC bit above a SoLSA exclusive access cell may also broadcast an escape PLMN code(see GSM 03.73) in SI3 and SI4. The real MCC is then broadcast in SI 4, 16 and 17 Rest Octets. The MCC valuefield is coded as specified in Figure 10.5.3/GSM 04.08 and Table 10.5.3/GSM 04.08.

MNC (12 bit field)In addition to the EXC_ACC bit above a SoLSA exclusive access cell may also broadcast an escape PLMN code(see GSM 03.73) in SI3 and SI4. The real MNC is then broadcast in SI 4, 16 and 17 Rest Octets. The MNC valuefield is coded as specified in Figure 10.5.3/GSM 04.08 and Table 10.5.3/GSM 04.08.

Cell Identity (16 bit field)The purpose of the Cell Identity is to identify a cell within a location area. The Cell Identity is coded as shown infigure 10.2/GSM 04.08 and table 10.5/GSM 04.08

LSA_ID (24 bit field)The purpose of the LSA_ID field is to identify a LSA. The LSA ID value field is specified in GSM 03.03.

(one category B Addition of feature Release 97and one release C Functional modification of feature X Release 98 Xonly shall be D Editorial modification Release 99marked with an X)

Reason forchange:

Today it is possible to put up to 4-5 LSA IDs in the SI 7, 8, 16 and 17 rest octets. If analternative with a shorter PLMN significant LSA ID is introduced it will be possible tobroadcast more LSA IDs. In the CR it is proposed to use 10 bits for the shorter LSA whichwould double the amount of LSA IDs broadcast.
