Hi Do you mean during event 3a ?
event3a is just a threshold for target cell generation, if no cells are found or met the criteria so the call will be drop or still kept on 3G till it drop.

Hi,
For 3G-2G exec Fail check :
- TRX availibility on 2G neighbours
- TCH congestion
- 2G frequency conflit
- Transmission, affect also synchronisation if you have E1/T1 clock mode
Best regards

No much details, I have a bad IRAT HOSR, after I checked the breakdown stats, it turned out it's due to failure in the execution phase. For the congestion, there is a a counter to check that (no available resources), I checked it, and it's zero,ya Ashraf
