capacity Formula
Number of Cells 410 RCB_1=Number of Cells / 410
No. of BHCA 500K RCB_2 =No of BHCA / 500k
Throughput of Signaling 14Mbps RCB_IpSig=Throughput of Signaling
/ 14Mbps
-
RCB and SBCX dimensioning principle
Detailed dimensioning principle with detailed traffic model:
RCB=2*MAX(RCB_1, RCB_2) + 2* RCB_IpSig
Simple dimensioning principle without detailed traffic model:
RCB = RUB + RCB_IpSig
RCB_IpSig =
2, if (RUB)

Iu
Iu-CS BIuCS = BIuCSData + BIuCSSig
Iu-PS BIuPS = BIuPSData + BIuPSSig
Iur BIur= BIurData + BIurSig
BIurData = (BIuCSData + BIuPSData) * RIur
GIPI=IP interface throughput / 1Gbps
APBE=MAX (ATM interface throughput / 140Mbps, STM-1 Interface / 4)
