(E)GPRS Capacity OptimizationIf AMR and/or HR is used add Dual rate TSL
If Dual rate not possible add TRX (need to check the PCU, A-bis and Gb capacity)
CS traffic management (change HO parameters, resource management parameters)
Increase nbr of dedicated PS timeslots
Yes
And
Configuration check
0.75*CMAX < peak_gprs_territory => Increase CMAX (or add/enable TRXs)
Peak_gprs_territory > (1-margin) * nbr of tsl in GTRXs (DR or FR) => enable more TRXs for GPRS
CDEF-ava_44>0 => Reduce CS traffic if PS is high (check Not used RTSLs!)
“GPRS inactivity” alarm (ref TN808)
If ho_61 is “big” => check territory upgrade reasons (PS triggers => Increase CDEF. CS triggers => Decrease CDEF if PS traffic is small, otherwise actions 1-4
Do nothing

“GPRS inactivity” alarm (ref TN808)
CDEF<ava_44 => Increase CDEF (check EDAP, PCU capacity first)
If ho_61 is “big” => check territory upgrade reasons (PS triggers => Increase CDEF. CS triggers => Decrease CDEF if PS traffic is small, otherwise actions 1-4
