Section: 4.16.1.3 Failed Secondary Node Additions without SN terminated bearers
Content: a) This measurement provides the number of failures when Secondary Node Addition without SN terminated bearers. The measurement is split into subcounters per failure cause. b) CC c) On MN failed receipt of SGNB ADDITION REQUEST ACKNOWLEGE Message or on transmission by MN of an SgNB Release Message after receipt of SGNB ADDITION REQUEST ACKNOWLEGE Message when Secondary Node Additions without SN terminated bearers. Each Secondary Node failed to add 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 Additions failed to setup at Secondary Node Additions without SN terminated bearers case. In case only a subset of per cause measurements is supported, a sum subcounter will be provided first. SGNB Addition Trigger Indication (TS 36.423[ Evolved Universal Terrestrial Radio Access Network (E-UTRAN); X2 Application Protocol (X2AP) ] [10]) excludes SN change, inter-eNB HO, intra-eNB HO. 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 ENDC.SNAdditionFailWoSnErab.Cause where Cause identifies the cause resulting in the Secondary Node Addition failure for without SN terminated bearers case. f) EUtranCellFDD EUtranCellTDD g) Valid for packet switched traffic h) EPS
