i have cssr problem, immediate assignment number increased suddenly, traffic is remained same(number of channel activation was about 6000 and suddenly 1 day become 16000 and remained)
no congestion, no uplink interference, bsc 6900
Actually stats were good, i mean rxqual and idle uplink interference. and dcr,assignment success,sd drop was ok. only immediate assignment..
i just saw a smilar case, i saw that someone changed the bcch and it was fixed.
