Section: 4.2.3.3 Number of E-RABs failed to modify the QoS parameter
Content: a) This measurement provides the number of E-RABs failed to be modified the QoS parameter. The measurement is split into subcounters per failure cause. b) CC c) On transmission by the eNodeB/RN of an E-RAB MODIFY RESPONSE message, each E-RAB failed to modify the QoS parameter is added to the relevant measurement per cause, the possible causes are included in TS 36.413[ Evolved Universal Terrestrial Radio Access Network (E-UTRAN); S1 Application Protocol (S1AP) ]  [9]. The sum of all supported per cause measurements shall equal the total number of E-RABs failed to modify the QoS parameter. In case only a subset of per cause measurements is supported, a sum subcounter will be provided first. d) Each measurement is an integer value. The number of measurements is equal to the number of causes plus a possible sum value identified by the .sum suffix. e) The measurement name has the form ERAB.ModQoSFailNbr.Cause where Cause identifies the cause resulting in the E-RAB Modify failure. f) EUtranCellFDD EUtranCellTDD g) Valid for packet switched traffic h) EPS
