Reply To: LOW TCH MHT and high SDCCH MHT


I mean : the call is setup in the cell, and after 15 seconds it is sent (handover) to another cell :
– which target cell exactly ?
– why ? (reason for HO ?)

The reason for long SDCCH is not important : first you must understand what is the problem with the TCH.

Maybe once you fix the TCH issue, you’ll see that the SDCCH is fine also.

Another investigation : do you think it could be a TRX HW issue ? Can you try to lock the TRX that gets most of the TCH allocation, and check if other TRX’s will carry the TCH longer ?
