hello,
for tch congestion, count the number of 48.008 ASSIGMENT FAILURE (cause: “no radio resource available”)
for sdcch congestion, it’s triky :
count the number of times a 48.058 CHANNEL REQUIRED is received by BSC but **not** followed by a 48.058 CHANNEL ACTIVATION (sent from BSC to BTS).
and
count the number of IMMEDIATE ASSIGN REJECT (available only if the feature is activated)
cheers
