This paging counter in MSC will be separated per BSC. Only BSC which has BTS number more than 75% in the

NPI cluster will be counted. if less than 75%, that BSC will be excluded.

Fo 3G only RNC in Padang, Palembang).

This paging counter in MSC will be separated per LAC. Only LAC which has BTS number more than 75% in the

Relative Improvement Target

target improvement value =

baseline + (space improvement X relative improvement target)

for example:

baseline = 95%

if relative improvement target is 10%:

target improvement value = 95% + (1-95%)x10% = 95% + 0.5% = 95.5 %

baseline = 95%

if relative improvement target is 15%:

target improvement value = 95% + (1-95%)x15% = 95% + 0.75% = 95.75 %

baseline = 80%

if relative improvement target is 40%:

target improvement value = 80% + (1-80%)x40% = 80% + 8% = 88 %

for KPI which is the smaller the better:

baseline = 2%
