All events concerning inter-RAT measurements are labelled 3x where x is a,b,c, .Event 3a: The estimated quality of the currently used UTRAN frequency is below a certain threshold and the estimated quality of the other system is above a certain threshold.Event 3b: The estimated quality of other system is below a certain threshold.Event 3c: The estimated quality of other system is above a certain threshold.Event 3d: Change of best cell in other system.Triggering conditions:Equation 1:The variables in the formula are defined as follows:QUsed is the quality estimate of the used UTRAN frequency.TUsed is the absolute threshold that applies for the used frequency in that measurement.H3a is the hysteresis parameter for event 3a.Equation 2:The variables in the formula are defined as follows:MOther RAT is the measurement quantity for the cell of the other system.CIOOther RAT is the cell individual offset for the cell of the other system.TOther RAT is the absolute threshold that applies for the other system in that measurement.H3a is the hysteresis parameter for event 3a.Leaving triggered state conditions:Equation 3:The variables in the formula are defined as follows:QUsed is the quality estimate of the used UTRAN frequency.TUsed is the absolute threshold that applies for the used frequency in that measurement.H3a is the hysteresis parameter for event 3a.Equation 4:The variables in the formula are defined as follows:MOther RAT is the measurement quantity for the cell of the other system.
