Intra-Frequency Measurements 

Event 1a: Add a Cell to Active set, Reporting Range (Add Radio Link)Event 1b: Remove cell from active set (Remove Radio Link)Event 1c: Replace Cell with becomes stronger than any in Active SetEvent 1d: The Best Cell Change, when any (Active Set, Monitored set, and Detected) cell becomesstronger 

Event 1e: A Primary CPICH becomes better than an absolute threshold 

Event 1f : A Primary CPICH becomes worse than an absolute threshold 

Inter-Frequency MeasurementsEvent 2a: Change of Best FrequencyEvent 2b: The estimated quality of the currently used frequency is below a certain threshold and theestimated 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 threshold (activeCompress Mode)

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 DeactivateCompress Mode)

Inter-System Measurements

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

Traffic Volume measurement reporting criteria

Contains the measurement reporting criteria information for a traffic volume measurement EventEvent 4a : Transport Channel Traffic Volume exceeds an absolute threshold Event

Event 4b : Transport Channel Traffic Volume becomes smaller than an absolute threshold 

Quality Measurement reporting criteria

Event5a: Number of bad CRCs on a certain transport channel exceeds a threshold 

UE Internal measurements:

Parameter: UTRA carrier RRSI (intra or interfrequency), UE Transmittedpower, UE Rx-Tx Time

differenceEvent 6a:The UE Tx power becomes larger than an absolute threshold 

Event 6b:The UE Tx power becomes less than an absolute threshold Event 6c:The UE Tx power reaches its minimum valueEvent 6d:The UE Tx power reaches its maximum value

Event 6e:The UE RSSI reaches the UE's dynamic receiver range

Event 6f:(FDD) The UE Rx-Tx time difference for a RL included in the active setbecomes larger than anabsolute threshold(1.28 Mcps TDD): The time difference indicated by TADV becomes larger than an

absolute threshold Event 6g:The UE Rx-Tx time difference for a RL included in the active set becomesless than an absolutethreshold 

Mobile UE Events

Event 7a: The UE position changes more than an absolute threshold Event 7b SFN-SFN measurement

changes more than an absolute threshold Event 7c: GPS time and SFN time have drifted apart more than an absolute threshold
