Reply To: Tch Failure in common bcch


Thx for the details rachid,

Well, I’m not a nokia expert, but perhaps you should check your parameters : it’s possible that you push MS too much in the inner segment ? MS will suffer poor RXLEV, and fail to seize the TCH.

Second possibility, which happen a lot in case of dualband cells : swap feeders… the inner segment of cell A is actually transmitting on the antenna of cell B…

Other than that, I leave it to nokia experts 🙂
