On cell level..
check your network report how channels are defined on cell bases.
I.e. no. of duel rates in double(if TCH defined as duel rate) and Full rates(WITHOUT dedicated GPRS,SIGNALLING)
A-Calculate above TCH using ERLB(rough) with .02% blocking probablity due TCH assignment failiure in real time.
B- Calculate BBH (bouncing busy hour erlang).
B/A*100= utlization.. on cell base.
On network level..
A-Total TCH defined in network (twice for duel)
B-Total Erlang generated by network in BBH period
B/A*100 and average of this for working days. will give utilization
