RNC Traffic Counters System
Traffic.Load.RNC
AMR Erlang:
VS.CSLoad.Erlang.Equiv.RNC
The RNC periodically takes the samples of the equivalent Erlang values of all services in the
CS domain. At the end of the measurement period, the RNC calculates the average sample.
PS DL traffic:
VS.PSLoad.DLThruput.RNC
The RNC periodically takes the samples of the downlink traffic values (in kbit/s) of all services
in the PS domain. At the end of the measurement period, the RNC calculates the average
sample.
PS UL traffic:
VS.PSLoad.ULThruput.RNC
The RNC periodically takes the samples of the uplink traffic values (in kbit/s) of all services in
the PS domain. At the end of the measurement period, the RNC calculates the average
sample.

RNC Traffic Counters System
RB.RNC
Mean Number of RB about CS Domain at Different UL and DL Bit Rates
The RNC periodically takes a sample of the number of RBs about CS domain at
each of the UL and DL rates. At the end of the measurement period, the RNC
divides the sum of the numbers of RBs at one bit rate by the number of samples to
get the average number

Cell Traffic Counters System
Traffic.cell
This traffic measurement is for Iub interface
The measurement value can be based on:
Common transport channel
FACH, RACH, PCH
Dedicate transport channel
Based on different Qos
These value are total traffic throughput on Iub Interface
The unit is Byte

VS.RB.ULConvCS.64
Downlink
VS.RB.DLConvCS.64
The RNC periodically takes a sample of the number of CS conversational service
RBs with different bit rates. At the end of the measurement period, the RNC
divides the sum of the numbers of conversational service RBs with each bit rate by
the number of samples to obtain the average number

HSDPA.cell
Average Number of UEs in CELL_HSDPA State (Cell)
VS.HSDPA.UE.Mean.Cell
The RNC periodically takes a sample of the number of UEs in CELL_HSDPA state.
At the end of the measurement period, the RNC calculates the sample average
Mean Throughput of Mac-d flows (Cell)
VS.HSDPA.MeanChThroughput
When a HSDPA cell transmits data, the RNC measures the times (in millisecond)
per Mac-d flow send data and number of bytes transmitted. At the end of the
measurement period, the RNC divides the number of total bits by the times perMac-d flow send data to obtain the mean throughput.

HSDPA.cell
Number of Bytes Send in Mac-d flow (Cell)
VS.HSDPA.MeanChThroughput.TotalBytes
When a HSDPA cell transmits data, the RNC measures the number of bytes
transmitted
Mean number of Mac-d flows (Cell)
VS.HSDPA.MACD.Mean.Cell
This is a gauge acquired value that represents the time averaged observed value
of the number of MACD flows on a per cell basis. This gauge variable is such that
the SRNC increments its value when it instantiates a Mac-d flow and decrementsits value when a Mac-d flow is deleted
