5. RF Optimization Major activities:
1. Plan basic testing, Route identification, DT allocation, RNO Engineer allocation for next day
2. Coordination with Drive tester & conduct end to end basic testing activity, Issue rectification during basic
testing(Latching Issue, CSFB Issue, Less Throughput Issue, Cell reserve/unreserve)
3. Compilation of whole day work & share RF dashboard by each Circle lead end of the day
4. SRVCC, CSFB, PSHO & FR-LTE testing(Coordination with Drive tester, CSFB Priority Change, B2- Threshold change,
After activity revert of changes)
5. 4G-4G/ 4G-3G/ 4G-2G Neighbor addition coordination with SON Team & Publish dashboard for Neighbor Update
6. TAC change activity end to end coordination & completion
7. During Basic testing if latching issue found site health checkup, VSWR check, configuration check, site soft reset as
per requirement
8. 2G/3G to LTE cell reselection and FRLTE definition in 3G RNC/Sites and 2G BSC/Sites, take up with BSNL team & end
to end follow up for Implementation
9. Cluster Drive in Major Cities where basic testing has been completed, Identification of poor patch, site physical/
parametric change, redrive after cluster optimization
10. RET Serial Number Collection, Site where RET Serial Number not received RET Scan, RET configuration in site & RET
change

13. Major RF KPIs
Below are the Major RF KPIs which we work on daily basis:
 RRC Connection Success Rate(All) (%)
 RRC Congestion
 RRC Drop Rate(%)
 ERAB Setup Success Rate (%)
 VOLTE ERAB Setup Success Rate
 DROP Call Rate (%)
 ERAB Drop Rate - PS (%)
 ERAB Drop Rate-VoLTE (%)
 Data Volume DL(MB)
 Data Volume UL(MB)
 Data Volume - Total (GB)
 Average Per user throughput (DL) Mbps
 Average Per user throughput (UL) Mbps
 VOLTE Traffic (Erlang)
 E-UTRAN Cell availability (%)
 Intra Frequency HO Out Success Rate(%)
 VOLTE Intra Freq HO out Success Rate
 PS handover success rate(LTE intra system) (%)
 Inter RAT HO out Success Rate (GERAN) (%)
 Inter RAT HO out Success Rate (UTRAN) (%)
 CSFB Preparation success rate

14. Major RF KPIs formula & Action Plan for Improvement
 RRC Connection Success Rate(All) (%):
Major Checks:
• Operational Issue check – Outage, Alarm, High VSWR, Configuration issue(Sec-0 should have one RRH, Sec-1,2 should have one RRH)
• If Traffic is very high & site is overshooting, we recommend down tilt in cell
• If site hangs, RRC SR becomes zero or very less suddenly site restart is recommended
 ERAB Setup Success Rate (%):
Similar actions are being taken for Improving Erab setup success rate(down tilt, restart, Outage/alarm rectification)
 Average Per user throughput (DL) Mbps:
Major Checks:
• Operational Issue check – Outage, Alarm, High VSWR, Configuration issue
• If connected user is very high & cell traffic is very high we down tilt the site to dominate the coverage & improves user throughput
• Sometimes high packet loss causes poor DL Throughput, Need to improve packet loss to improve DL user throughput
 Intra Frequency HO Out Success Rate(%):
 Major Checks:
• Neighbor Audit required for Improving Intra Freq HOSR, Wrong TAC, PLMN, PCI, Cell ID mapping in neighbor cause poor intra freq hosr
• Neighbor refresh(Neighbor deletion & recreation) required to improve intra freq hosr

15. Major RF KPIs formula & Action Plan for Improvement
 Inter RAT HO out Success Rate (GERAN) (%):
• For Improving SRVCC to GERAN – 4G to 2G Neighbor audit is required, If any 2G neighbor is having wrong Cell ID, BCCH, BSIC, LAC definition SRVCC will be
degraded, Need to correct the definition.
 Inter RAT HO out Success Rate (UTRAN) (%):
• For Improving SRVCC to UTRAN – 4G to 3G Neighbor audit is required, If any 3G neighbor is having wrong Cell ID, PSC, LAC definition SRVCC will be
degraded, Need to correct the definition.
