Section: 4.4.8.1 Time Period the Requested IP throughput of GBR services Cannot be Achieved in the Cell
Content: a) This measurement provides time period the requested IP throughput cannot be achieved in the cell. The measurement is split into sub-counters per QoS class level (QCI). Concerning operator specific QCIs their definition is vendor specific. b) CC c) This measurement is obtained by summing up the pre-defined sampling intervals during which the requested IP throughput cannot be achieved in the cell and reporting accumulated value at the end of measurement period. The IP throughput defined in TS 36.314[ Evolved Universal Terrestrial Radio Access  (E-UTRA); Layer 2 - Measurements ]  is used to evaluate time period during which the QoS is not satisfied by comparing the IP throughput with the guaranteed bit rate of the GBR services. The measurement period and number of samples during one measurement period are provided by the operator. d) Each measurement is an integer value (Unit: ms). e) The measurement name has the form Cell.ReqThpNotAchieved.QCI where QCI identifies the E-RAB level quality of service class. f) EUtranCellFDD EUtranCellTDD g) Valid for packet switched traffic. h) EPS. i) In case the duration interval provided with this measurement is followed with the on restricting the UEs for network access to the cell policy executed via ACB as mentioned in A.5 then this measurement provides “Time period in Active ACB triggered via requested QoS cannot be achieved”. The measurement can be executed with grouping of couple of QCIs to a common monitoring to distinguish between voice and data services. The IP throughput measurements is used as a reference on how to evaluate the quality of provided services to end user in observed cell. They shall be obtained directly in the eNB as internal measurements during each sampling period.
