This message is sent by the network on the PBCCH or PACCH giving information on 3G Neighbour Cells and additional measurement and reporting parameters. This message shall not be segmented across more than one RLC/MAC control block by using the procedures specified in sub-clause 9.1.12a. If not all information fits into one instance of the PSI3quater message, the PSI3quater message can be repeated. Special requirements for the transmission of this message apply on PBCCH, see 3GPP TS 05.02.

Table 11.2.21b.2: PSI3 quater information element details
PAGE_MODE (2 bit field) |
PSI3_CHANGE_MARK (2 bit field) |
PSI3_QUATER_INDEX (4 bit field) |
PSI3_QUATER_COUNT (4 bit field) |
GPRS REP PRIORITY Description REP_PRIORITY bit: The use of these bits is defined in sub-clause 5.6.3.5 ("GPRS Report Priority Description"). |
3G Neighbour Cell Description The building of the 3G Neighbour Cell list and the ordering of indices within each Radio Access Technology is described in sub-clause 5.6.3.1 ("Deriving the 3G Neighbour Cell list from the 3G Neighbour Cell description"). Index_Start_3G (7 bit) This optional information element indicates the value of the first index to use to build this instance of the 3G Neighbour Cell list. When missing, the value 0 is assumed. See sub-clause 5.6.3.1. Absolute_Index_Start_EMR (7 bit) This parameter indicates the value to be added to the indexes of the 3G Neighbour Cell list for reporting 3G Cells with the PACKET ENHANCED MEASUREMENT REPORT message (see sub-clause 5.6.3.3). If different values are received for this parameter in different instances of this message, the instance with the highest index shall be used. NOTE: This parameter is not used for reporting 3G Cells with the PACKET MEASUREMENT REPORT message, see sub-clause 11.2.9. UTRAN FDD Description: FDD_CELL_INFORMATION Field (p bit field) UTRAN TDD Description: TDD_CELL_INFORMATION Field (q bit field) If parameter m in Table 11.2.9b.2.b is equal to 31, this indicates that the corresponding UARFCN shall be included in the GPRS 3G Cell Reselection list (see sub-clause 5.6.3.7); no index shall be allocated in the 3G Neighbour Cell list. |
3G MEASUREMENT PARAMETERS Description |
3G Initial Dedicated Mode Reporting Description These parameters shall only be used in initial 3G neighbour cell reporting in dedicated mode. 3G_BA_IND (1 bit field) The 3G_BA_IND is needed to identify set of 3G Neighbour Cell information used for reporting in dedicated mode. The value received is reflected in the MEASUREMENT REPORT and ENHANCED MEASUREMENT REPORT messages, see 3GPP TS 04.18 / sub-clause 3.1.1.2.1 Parameters for Measurements and Reporting. The other fields of this Description are used for measurements as defined in 3GPP TS 05.08. |
