RNC Traffic Counters System

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

Traffic.Load.RNC

RB.RNC

AMR.RNC


5/22



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.

Bit Rates

VS.RB.DLInterPS.384.RNC








VS.RB.DLBkgPS.384.RNC







VS.RB.DLBkgPS.8.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







VS.RB.ULBkgPS.8.RNC


8/22



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 aboutCS 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

Bit RaMean Number of AMR Speech UEs at Different UL and

DL Bit Rates

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

Downlink

VS.MAC.SRNCIubBytesPSStr.Tx

VS.MAC.SRNCIubBytesPSInt.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


15/22



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

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



17/22



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.


18/22



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 gaugevariable 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


VS.MinRTWP

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



20/22



RTWPTCP.Cell
