Hi all,
I am working for GSM network, specifically for Pico BTS (indoor solution). Some BTS’s are facing TCH assigment failure problem. I would like to know what is the cause of this issue and where i can good information to learn more about KPIs. Last week i got another problem with SDCCH real blocking i saw at the level counter that the counter that was increased was sdcch_abis_fail_call
. I would like to know what i do need to check?
Thx in advance for the support.
