1.) SCR formula:
Call Completion Rate = E2/E0
E2: Call Completion Times
E0: Seizure Attempts
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).
RNC Banjarmasin and Makassar are excluded.
2.) CSSR in radio level:
2.1.) CSSR 2G:
'= (100 * K3013A / K3010A)
Successful Attempts : ASSIGNMENT COMPLETE message.
Total Attempts : ASSIGNMENT REQUEST message including Direct Retry
2.2.) SP Access Rate 3G:
=rrc_serv_suc_rate*number of sprab_suc / Number of sprab_att*100%
number of sprab_suc = VS.RAB.SuccEstab.AMR
number of sprab_att= VS.RAB.AttEstab.AMR
1.) Paging in MSC per LAC
100 * ([Number of First Paging Responses to A Interface (times)]+[Number of Repeated Paging Responses to A
Interface (times)])/([Number of First Pagings from A Interface (times)])
This paging counter in MSC will be separated per LAC. Only LAC which has BTS number more than 75% in the
NPI cluster will be counted.
2.) Paging in BCS for Medan and Pekanbaru
2.1.) For 2G
Paging overload rate= (MSG CCCH LOAD IND(PCH) Message Sent on Abis Interface + PACKET CCCH LOAD IND
Messages Sent on Abis Interface) / (Delivered Paging Messages for CS Service + Delivered Paging Messages for
PS Service) x 100%
2.2.) For 3G

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%
