Event Type Intrafrequency WCDMA Events Event 1A : Serving cell CPICH enters the reporting range Event 1B : Serving cell CPICH leaves the reporting range Event 1C : Neighbour Cell CPICH becomes better than the serving cell CPICH Event 1D : Change of best cell Event 1E : Serving cell CPICH becomes better than an absolute threshold Event 1F : Serving cell CPICH becomes worse than an absolute threshold Interfrequency WCDMA events Event 2A : Change of best frequency Event 2B : The estimated quality of the currently used frequency is below a certain threshold and the estimated quality of a non-used frequency is above a certain threshold Event 2C : The estimated quality of a non-used frequency is above a certain threshold Event 2D : The estimated quality of the currently used frequency is below a certain threshol Event 2E : The estimated quality of a non-used frequency is below a certain threshold Event 2F : The estimated quality of the currently used frequency is above a certain threshold I...

There are several events in UMTS and LTE. Here you can find Measurement report comparison between UMTS and LTE. UMTS event List : Event 1A,Event 2D and many more Measurement reports in LTE Event A1 (Serving becomes better than threshold) Event A2 (Serving becomes worse than threshold) Event A3 (Neighbor becomes offset better than serving) Event A4 (Neighbor becomes better than threshold) Event A5 (Serving becomes worse than threshold1 and neighbor becomes better than threshold2) Event B1 (Inter RAT neighbor becomes better than threshold) Event B2 (Serving becomes worse than threshold1 and inter RAT neighbor becomes better than threshold2) Measurement report UMTS and LTE comparison LTE Event A1  – Serving becomes better than threshold and  UMTS e2f  – The estimated quality of the currently used frequency is above a certain threshold In LTE this may be used to stop looking for a cell on a different frequency or technology, as e2f is used in UMTS. LTE Event A2 ...
