Section: 4.2.2.4 Number of E-RAB successfully released
Content: This measurement provides the number of E-RABs successfully released. The measurement is split into subcounters per E-RAB QoS level (QCI). CC On transmission by the eNodeB/RN of an E-RAB RELEASE RESPONSE or UE CONTEXT RELEASE COMPLETE, or E-RAB Release Indication or a RESET ACKNOWLEDGE to MME/DeNB; or E-RAB is released successfully by the eNB/RN after receiving PATH SWITCH REQUEST ACKNOWLEDGE or PATH SWITCH REQUEST FAILED messageby which some or all E-RABs in the corresponding PATH SWITCH REQUEST are to be released; or the E-RAB is released successfully at the source EUtran cell by the eNB/RN after receiving RRCConnectionReconfigurationComplete message from the UE, indicating a successful intra-eNB/RN handover (see TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [8]); or the E-RAB released successfully by source eNB/RN after receiving UE CONTEXT RELEASE from another eNB/DeNB; or on receipt by the eNB/RN of a RESET ACKNOWLEDGE message from MME/DeNB . E ach corresponding E-RAB successfully released is added to the relevant measurenment 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 same E-RAB shall not be counted repeatly but only one in case it appears more than one time in the same or different messages triggering this measurement. The sum of all supported per QCI measurements shall equal the total number of E-RABs fully released. In case only a subset of per QCI measurements is supported, a sum subcounter will be provided first. 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. The measurement name has the form ERAB.RelSuccNbr.QCI where QCI identifies the E-RAB level quality of service class. EUtranCellFDD EUtranCellTDD Valid for packet switched traffic EPS
