Kita perlu menset
GSM.Radio.RxGain
agar FER cukup baik & MS memperoleh IP address.
Masuk ke CLI.
Set
devconfig GSM.Radio.RxGain 44
Nilai default GSM.Radio.RxGain 48
Kemudian Reboot
gprs list ch -v
Pastikan FER agak lebih besar sedikit dari 0%, misalnya
PDCH ARFCN=50 TN=1 FER=0% Reservations=() USFList=( 1=>free 2=>free 3=>free 4=>free 5=>free 6=>free) TFI=() PDCH ARFCN=50 TN=2 FER=0% Reservations=() USFList=( 1=>free 2=>free 3=>free 4=>free 5=>free 6=>free) TFI=()
Jika belum memuaskan, ulangi prosedur di atas. Set lagi GSM.Radio.RxGain
Jika FER sedikit di atas 0%, semoga MS memperoleh IP address.
Cek
gprs list ms -cxv
Menaikan Channel GPRS
OpenBTS> load
== GSM == SDCCH load: 0/4 TCH/F load: 0/5 AGCH/PCH load: 0,0 Paging table size: 0 Transactions: 0 T3122: 2000 ms (target 5000 ms) == GPRS == current PDCHs: 2 utilization: 0%
Ada 2 PDCHs untuk GPRS, ini bisa di naikan, misalnya
config GPRS.Channels.Min.C0 5
Cek load
OpenBTS> load
== GSM == SDCCH load: 0/4 TCH/F load: 0/2 AGCH/PCH load: 0,0 Paging table size: 0 Transactions: 0 T3122: 2000 ms (target 5000 ms) == GPRS == current PDCHs: 5 utilization: 0%
Sekarang PDCHs menjadi 5 dan TCH/F menjadi 2
