3GPP44.060General Packet Radio Service (GPRS)Mobile Station (MS) - Base Station System (BSS) interfaceRadio Link Control / Medium Access Control (RLC/MAC) protocolRelease 17TS

This optional message is sent by the network on the PBCCH giving information for measurement reporting and network controlled cell reselection. 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 message, the remaining information will be sent in other instances of the PSI5 message. The message is sent on PBCCH only if so indicated in PSI1.

Table 11.2.23.2: PSI5 information element details

The optional PSI5 message contains broadcast measurement parameters for Network Control (NC) measurements containing the NC Measurement Parameters. The NC Measurement parameters struct shall only exist in one instance of the PSI5 message. If the NC Measurement parameters struct is included in more than one instance, the value of the struct in the instance with the highest index shall be valid and all others shall be ignored.

PAGE_MODE (2 bit field)
This field is defined in sub-clause 12.20.

PSI5_CHANGE_MARK (2 bit field)
The PSI5_CHANGE_MARK field is changed each time information has been updated in any of the individual instances of the PSI5 message. A new value indicates that the mobile station shall re-read the information from all PSI5 messages. Range: 0 to 3. The coding of this field is network dependent.

PSI5_INDEX (3 bit field) and PSI5_COUNT (3 bit field)
The purpose of the PSI5_INDEX field and the PSI5_COUNT field is to indicate the number of individual messages within the sequence of PSI5 messages and to assign an index to identify each one of them. The PSI5_INDEX field is binary coded, range: 0 to 7, and provides an index to identify the individual PSI5 message. The PSI5_COUNT field is binary coded, range: 0 to 7, and provides the PSI5_INDEX value for the last (highest indexed) message in the sequence of PSI5 messages.

NETWORK_CONTROL_ORDER (2 bit field)
The NETWORK_CONTROL_ORDER field is coded according to the following table (for definition of NCx see 3GPP TS 45.008):

bit
2 1
0 0 NC0
0 1 NC1
1 0 NC2
1 1 Reserved

If the NETWORK_CONTROL_ORDER parameter = NC0, then the other parameters in the NC Measurement parameters struct may be omitted. If the NETWORK_CONTROL_ORDER parameter indicates NC1 or NC2 and the other parameters are omitted, the default value for these parameters shall be assumed.

NC_NON_DRX_PERIOD (3 bit field)
This field indicates the minimum time the mobile station shall stay in non-DRX mode after an NC-measurement report has been sent. The field is coded according to the following table:

bit
3 2 1
0 0 0 No non-DRX mode after a measurement report has been sent.
0 0 1 0,24 s
0 1 0 0,48 s (default value)
0 1 1 0,72 s
1 0 0 0,96 s
1 0 1 1,20 s
1 1 0 1,44 s
1 1 1 1,92 s

NC_REPORTING_PERIOD_I (3 bit field)
NC_REPORTING_PERIOD_T (3 bit field)
These fields indicate the time period for cell reselection measurement reporting for packet idle mode (I) and packet transfer mode (T), respectively. The field is coded according to the following table:

bit
3 2 1
0 0 0 0,48 s
0 0 1 0,96 s
0 1 0 1,92 s
0 1 1 3,84 s (default value for NC_REPORTING_PERIOD_T)
1 0 0 7,68 s
1 0 1 15,36 s
1 1 0 30,72 s
1 1 1 61,44 s (default value for NC_REPORTING_PERIOD_I)

NCC_PERMITTED (8 bit field)
This field is a bitmap of NCCs for which the mobile station is permitted to report measurement; this bitmap relates to NCC part of BSIC (see coding field in 3GPP TS 44.018).

ENH Reporting Parameters (Enhanced Measurement reporting parameters)

Report_Type (1bit)
This parameter is used to indicate to the mobile station to use the PACKET ENHANCED MEASUREMENT REPORT message or the PACKET MEASUREMENT REPORT message for (NC) reporting:

Bit
0 The MS shall use the PACKET ENHANCED MEASUREMENT REPORT message for (NC) reporting
1 The MS shall use the PACKET MEASUREMENT REPORT message for (NC) reporting.

REPORTING_RATE (1 bit)
This parameter is used for measurements, see 3GPP TS 45.008.

Bit
0 normal rate reporting
1 Reduced reporting rate allowed.

INVALID_BSIC_REPORTING (1 bit)
This field specifies if cells with invalid BSIC and allowed NCC part of BSIC are allowed to be reported or not, see 3GPP TS 45.008.

Bit
0 Report on cells with invalid BSIC and allowed NCC part of BSIC is not allowed.
1 Report on cells with invalid BSIC and allowed NCC part of BSIC is allowed. In this case NCC_PERMITTED is required.
