    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

    Intersystem Events
    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 Events
    Event 4A : Transport Channel Traffic Volume becomes larger than an absolute threshold
    Event 4B : Transport Channel Traffic Volume becomes smaller than an absolute threshold
    Event 5A : A predefined number of bad CRCs are exceeded

    UE internal events
    Event 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 value
    Event 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 set becomes larger than an absolute 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 becomes less than an absolute threshold

    UE positioning 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
    Event 7D : GANSS time and SFN time have drifted apart more than an absolute threshold
