3G WCDMA Event 1A, 1B, 1C dan lainnya

Di jaringan 3G, untuk analisa dan optimasi, setidaknya kita harus mengetahu jenis event apa saja yang ada. Berikut ini saya ambil dari website sharetechnote keterangan mengenai event-event yang ada di jaringan 3G.

WCDMA Measurement Report Trigger (EVENT for Measurement Report) Event Type Description 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 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 Event 2A 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 2B The estimated quality of other system is below a certain threshold Event 2C The estimated quality of other system is above a certain threshold Event 2D Change of best cell in other system 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 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 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
