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 HUAWEI TECHNOLOGIES CO., LTD HUAWEI Confidential Page RNC Traffic Counters System  AMR.RNC  Mean Number of RB about CS

RNC Traffic Counter Chapter Cell Traffic Counter HUAWEI TECHNOLOGIES CO., LTD HUAWEI Confidential Page 10 RNC Traffic Counters System  In cell level, the counters related to traffic can be divided into:  Traffic.cell  RB.cell  HSDPA.cell  RTWPTCP.cell HUAWEI TECHNOLOGIES CO., LTD HUAWEI Confidential Page 11 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 HUAWEI TECHNOLOGIES CO., LTD HUAWEI Confidential Page 12 Cell Traffic Counters System  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 HUAWEI

(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 HUAWEI TECHNOLOGIES CO., LTD HUAWEI Confidential Page 17 Cell Traffic Counters System  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 HUAWEI TECHNOLOGIES CO., LTD HUAWEI Confidential Page 18 Cell Traffic Counters System  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 −
