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

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

� In cell level, the counters related to traffic can be divided into:
� Traffic.cell
� RB.cell
� HSDPA.cell
� RTWPTCP.cell
HUAWEI TECHNOLOGIES CO., LTD. Page 12HUAWEI Confidential
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

− 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 per
Mac-d flow send data to obtain the mean throughput.

− 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
