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 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

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 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
