Hai bijoy,
Thanks for your reply. Just wonder is it the TS for GSM is 16 Kbps? and is it GPRS TS size is same with GSM, but total TS per connection is different per user. Is 64 kbps is used as assumption in UMTS
I’ve got an information about data erlang from “GSM GPRS and EDGE Performance Evolution Towards 3G UMTS”, John Wiley and Sons, that data erlang:
data erlanga = (Total number of transmitted Radio Block Size * TTI frame duration)/Duration of Busy Hour
