Section: 4.2.1.4 Number of additional E-RABs attempted to setup
Content: a) This measurement provides the number of additional E-RABs attempted to setup. The measurement is split into subcounters per E-RAB QoS level (QCI). b) CC. c) On receipt by the eNodeB/RN of an E-RAB SETUP REQUEST message, each requested E-RAB in the message is added to the relevant measurement per QCI, the possible QCIs 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 QCI measurements shall equal the total number of additional E-RABs attempted to setup. In case only a subset of per QCI 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 QCIs plus a possible sum value identified by the .sum suffix. e) The measurement name has the form ERAB. EstabAddAttNbr.QCI where QCI identifies the E-RAB level quality of service class. f) EUtranCellFDD EUtranCellTDD g) Valid for packet switched traffic. h) EPS. i) This measurement is to support the Accessibility KPI “E-RAB Accessibility” defined in [13]. Another usage of this measurement is to support the coverage ratio (CR) calculation for EE coverage area determination in [21].
