B A B IV PENGUJIAN SISTEM DAN ANALISA 4.1 Pengujian Sistem dan Analisa Pada bab ini dilakukan pengujian berdasarkan data kuantitatif yang bertujuan untuk mengetahui prosentase keberhasilan sistem Direct Tunnel. Pengujian sistem yang dilakukan adalah : 4.1.1 Monitoring Performansi Data Counter Optimasi jaringan adalah proses penjagaan / peningkatan kualitas dari jaringan seluler. Setiap operator jaringan selular menetapkan suatu standar nilai (parameter) Quality of Service (QoS) agar mencapai suatu KPI (Key Performace Indicator) dioperator tersebut, dimana melalui nilai QoS ini dapat ditentukan baik atau tidaknya kualitas suatu jaringan di tempat tertentu. Data-data mengenai QoS yang terjadi diambil kemudian dibandingkan dengan nilai parameter standar. Apabila terjadi ketidaksesuaian nilai yang terjadi di jaringan tersebut dengan parameter standar maka perlu dilakukan tindakan optimasi jaringan. Adapun parameter tersebut adalah PDP Success Rate. PDP Success Rate PDP Success Rate adalah angka keberhasilan proses berlangsungnya hubungan atau attach pada jaringan GSM dari awal proses signalling sampai dengan selesainya proses attach. Prosentase Attach Success Rate dapat dikatakan bagus jika lebih besar dari 90 % (prosentase KPI yang disetujui oleh operator khususnya Indosat adalah 95 %) dari seluruh atttach yang terjadi di area yang bersangkutan. Cara Pengujian : Pengujian PDP Success Rate dilakukan menggunakan handset dengan setting APN yang akan diproses. BAB IV Pengujian Sistem dan Analisa 31

Contoh : Download data using handset (FTP transfer) : Hasil : Gambar 4.1 Download data using handset (FTP transfer) Monitoring Performansi Tabel 4.2 Performansi PDP success rate Analisa : Dari hasil monitoring performansi diatas, diketahui bahwa untuk RNC Surabaya sudah berhasil diaktifkan Direct Tunnel sekitar jam 03:00 WIB. Dengan demikian dapat disimpulkan performansi PDP success rate untuk SGSN Surabaya sudah berhasil dengan baik karena lebih besar dari 90 %. BAB IV Pengujian Sistem dan Analisa 33
