Traffic Model

AMR12.2 (Erl) 0.035 0.035
CS64 (Erl) 0.000 0.000
PS64 (kbit) 144.00 96.00
PS128 (kbit) 0.00 192.00
PS384 (kbit) 0.00 288.00
HSPA (kbit) 576.00 2304.00
Total 720.00 2880.00

Assumptions
Subscriber per site (S111) is 586
SHO overhead 20%
Retransmission for PS 1%
Burst Ratio 40%

Traffic of voice
0.035*586*(1+20%) = 24.612 Erl
GoS=2% do =33 Erl

CE for voice peak traffic
33 * 1=33 CE

CE for UL R99 PS64k
((144*586)/(64*0.2*3600))*3*(1 20%)*(1 1%)*(1 40%) = 10CE

Same you can calculate for other RAB Services and HSUPA.

Thanks
