Hi all,
Call drops in 3g can occur bcoz of many reasons. If is due to the RAN part so you need to make sure there is no pilot pollution when you are doing drive test. Also check the Ec/Io value. Normally call should go one even the Ec/Io is -18. Have a look at your link budget also. Which NodeBs are you using? Are you using TMAs on 3G?
