RNC Traffic Counters System

� In RNC, the counters related to traffic can be divided into:

� Traffic.Load.RNC

� RB.RNC

� AMR.RNC



� 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.



� RB.RNC

� Mean Number of RB about PS Domain at Different DL Bit Rates

− VS.RB.DLInterPS.384.RNC








− VS.RB.DLBkgPS.384.RNC










� RB.RNC

� Mean Number of RB about PS Domain at Different UL Bit Rates

− VS.RB.ULInterPS.384.RNC








− VS.RB.ULBkgPS.384.RNC










� 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

− VS.RB.DLConvCS.64.RNC

− VS.RB.ULConvCS.64.RNC



� AMR.RNC

� Mean Number of RB about CS Domain at Different UL and DL Bit RaMean

Number of AMR Speech UEs at Different UL and DL Bit Rates

− VS.AMR.RB.DL.12.2

− VS.AMR.RB.UL.12.2

Chapter 2 Cell Traffic Counter Chapter 2 Cell Traffic Counter



� In cell level, the counters related to traffic can be divided into:

� Traffic.cell

� RB.cell

� HSDPA.cell

� RTWPTCP.cell


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



� Traffic.cell

� Measurement value for different services on Iub interface

− Uplink

▪ VS.MAC.SRNCIubBytesPSStr.Rx

▪ VS.MAC.SRNCIubBytesPSInt.Rx

▪ VS.MAC.SRNCIubBytesPSBkg.Rx

− Downlink

▪ VS.MAC.SRNCIubBytesPSStr.Tx

▪ VS.MAC.SRNCIubBytesPSInt.Tx

▪ VS.MAC.SRNCIubBytesPSBkg.Tx



� RB.cell

� Average Numbers of CS Conversational Service RBs with Different Bit Rates

(Cell)

− Uplink

▪ 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



� RB.cell

� Average Number of PS Interactive Service RBs with Different UL and DL Bit

Rates (Cell)

− Uplink

▪ VS.RB.ULInterPS.DifferentServiceRate

▪ Different service rates are 8, 16, 32, 64, 128, 144, 256, 384

− Downlink

▪ VS.RB.DLInterPS.DifferentServiceRate




� RB.cell

� Average Number of PS Background Service RBs with Different UL and DL Bit

Rates (Cell)

− Uplink

▪ VS.RB.ULBkgPS.DifferentServiceRate


− Downlink

▪ VS.RB.DLBkgPS.DifferentServiceRate




� 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 per

Mac-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 decrements

its value when a Mac-d flow is deleted



� RTWPTCP.Cell

� Cell RX power measurement

− VS.MeanRTWP

▪ Mean RTWP of a cell, that is, mean

number of the sum of the RTWP values

reported in a certain period

− VS.MaxRTWP

▪ Maximum RTWP of a cell, that is,

maximum value among all the RTWP

values reported in a certain period

− VS.MinRTWP

▪ Minimum RTWP of a cell, that is, minimum value among all the RTWP




� RTWPTCP.Cell

� Cell TX power measurement

− VS.MeanTCP

▪ Mean TCP of a cell, that is, mean

number of the sum of the TCP values


− VS.MaxTCP

▪ Maximum TCP of a cell, that is,

maximum value among all the TCP


− VS.MinTCP

▪ Minimum TCP of a cell, that is, minimum value among all the TCP values




� RTWPTCP.Cell

� Non-HSDPA Cell TCP Values

− VS.MeanTCP.NonHS

− VS.MaxTCP.NonHS

− VS.MinTCP.NonHS

� HSDPA Cell TX power for HSDPA service

− VS.HSDPA.MeanRequiredPwr

− VS.HSDPA.MaxRequiredPwr

− VS.HSDPA.MinRequiredPwr
