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.

RB.RNC

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

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 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 Rates

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

Cell Traffic Counters System

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

Traffic.cell

RB.cell

HSDPA.cell

RTWPTCP.cell


12/22



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

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

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.



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 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



19/22



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




20/22



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
