periodCMEUG:1CellAdjust the counter so that the reported value is
the peak value of the whole measurement period1LLC Throughput
weighted by volumeCMEUG:2CellImprove the R9.1 counters "LLC
Throughput" to wieght the average by data volume. "Measure quality
where the traffic/revenue is".1Peak throughput across the Gb
interfaceCMEUG:3NSVCIGb dimensioning and trouble shooting.
Preferred solution is to have this counter on the SGSN side1QoS
weight per PDCHCMEUG:4CellMeasures the channel load in terms of QoS
weight1Multislot Utilisation Scanning counterCMEUG:5CellCount ratio
of assigned number of timeslots to MS timeslot capability1DL Buffer

no PDCH, lost radio link, no TFI etc1UL Access Success

mobility and number of interruptions due to cell changes, see also
CMEUG:101Number of Inter-PCU Cell UpdatesCMEUG:10CellSee CMEUG:9.
Note: Inter PCU cell updates affect GPRS performance more than
Intra PCU cell updates1Number of TBFs entering DL Delayed mode and
number of TBFs receiving data while in delayed
modeCMEUG:11PCUCounters to set parameters for the features "Delayed
DL TBF"1Number of TBFs entering Extended UL TBFmode and number of
TBFs receiving data while in Extended modeCMEUG:12PCUCounters to
set parameters for the features "Early set-up of DL TBF"1Number of
TBFs entering Early TBF set-up mode and number of TBFs receiving
data while in early set-up modeCMEUG:13PCUCounters to set
parameters for the features "Extend UL TBF"1Cell Traffic

performance from end-user perspective2"Number of TBF/PDCH" counted
per channel type (B-, G-, and E-PDCH)CMEUG:17CellExtends the R9.1
cell counter "# of TBFs/PDCH".2"PDCH utilization" per channel type
(B-, G-, and E-PDCH)CMEUG:18CellExtends the R9.1 cell counter
"ALLPDCHACTACC".2Fraction of time channel load is exceeding
TBFLIMITCMEUG:19CellMonitor channel load, same purpose as higer
priority counters CMEUG:5 and CMEUG:62Volume counter for
non-chargable trafficCMEUG:20CellTo measure the amount of MM and SM
related signalling2Number of Cell Updates per cell
relationCMEUG:21Cell neighboursSee CMEUG:9. Note: Inter PCU cell
updates affect GPRS performance more than Intra PCU cell
updates2RLC Data block per coding schemeCMEUG:22CellTo check coding
scheme behaviour and feedback this to terminal manufacturers and
system suppliers2Time from LLC PDU is received at Gb until it is
delivered to the MSCMEUG:23CellA Key Performance Indicater
complementing the LLC Throughput, relevant primarily for non-TCP/IP
traffic2Correlated Cell UpdatesCMEUG:24PCU?This is to see if some
users suffer from sequences of Cell changes. Good candidate for
R-PMO2PRIO 3 CountersTBF Lifetime

I.e. same purpose as preferred counters CMEUG:11 - 13.3
