Section: .4 Failed RRC connection establishment per failure cause
Content: a) This measurement provides the number of failed RRC establishment per failure cause. This measurement is to support LBO target setting and evaluation, see [15] b) CC c) Transmission of an RRCConnectionReject message by the eNodeB to the UE. Each transmitted RRCConnectionReject message caused by “congestion” is added to the measurement cause ‘Congestion’, when eNB receives an RRCConnectionRequest message and the RRC connection is not established because the eNB is going to Energy Saving mode is added to the measurement cause ‘EnergySaving’ and each transmitted RRCConnectionReject message caused by the other reasons is added to measurement cause ‘Unspecified’. d) Each measurement is an integer value. e) RRC.ConnEstabFaileNBCause.Congestion RRC.ConnEstabFaileNBCause.Unspecified RRC.ConnEstabFaileNBCause.EnergySaving f) EUtranCellFDD EUtranCellTDD g) Valid for packet switched traffic h) EPS i) The measurement is use to count ‘Failed RRC connection establishment related to load’ for LBO target setting and evaluation, see [15].
