Section: 4.1.1.3 Failed RRC connection establishments
Content: a) This measurement provides the number of RRC establishment failures for each establishment cause. b) CC c) Transmission of an RRCConnectionReject message by the eNodeB/RN to the UE or an expected RRCConnectionSetupComplete message not received by the eNodeB/RN. Each failed RRC connection establishment is added to the relevant per establishment cause measurement. The possible causes are included in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [8]. The sum of all supported per cause measurements shall equal the total number of RRC connection establishment failures. 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 RRC.ConnEstabFail.Cause where Cause identifies the establishment cause. f) EUtranCellFDD EUtranCellTDD g) Valid for packet switched traffic h) EPS i) One usage of this measurement is to support the coverage ratio (CR) calculation for EE coverage area determination in [21].
