Main Problem
Highlight :
Site JAJARSOLOMW all sectors, have degradation of CSSR PS, follow by
increments of Other Congestion

Analysis
RNC XPU Load
Highlight :
• JAJARSOLOMW located at RNC SOLO
- XPU SRN=2,SN=2,SSN=1
• XPU Load RNC SOLO
SRN=2,SN=2,SSN=1 decreased on 12
Sept 2013,
• For this case on JAJARSOLOMW, If
We compare XPU Load RNC SOLO
SRN=2,SN=2,SSN=1 and Rejection
due to Other Congestion at
JAJARSOLOMW not in-line. Might be
problem in NodeB board or other
possibility

Analysis
NodeB Board Configuration
CPU Board Load
Nexwave Design and Strategic
Highlight :
• Base on NodeB Board Configuration,
JAJARSOLOMW have 2 WBBP. These 2
WBBP located at CN=0,SRN=0,SN=1 and
CN=0,SRN=0,SN=3
• Base on CPU Board Load, we found
unbalance CPU Board Load, CPU Board
Load of
WBBP CabinetNo=0,SubrackNo=0,SlotNo
=3 reach 90%, and CPU Board Load of
WBBP CabinetNo=0,SubrackNo=0,SlotNo
=1 is 0%
• Proposed to rebalance CPU Board Load of
WBBP

Action
Check UL Group at NodeB MML Command
Highlight :
• After check WBBP board
CabinetNo=0,SubrackNo=0,SlotNo=1
already configured properly, check
Board sharring status.
• Base on NodeB MML Command, We
found ULGROUP for WBBP board
CabinetNo=0,SubrackNo=0,SlotNo=1
not configured
• Proposed to add ULGROUP for
WBBP board
CabinetNo=0,SubrackNo=0,SlotNo=1

Action
Check DL Group at NodeB MML Command
Highlight :
• Base on NodeB MML Command, We
found DLGROUP for WBBP board
CabinetNo=0,SubrackNo=0,SlotNo=1
not configured
• Proposed to add DLGROUP for
WBBP board
CabinetNo=0,SubrackNo=0,SlotNo=1

Result
Highlight :
• CPU WBBP Board Load already
balanced
• Rejection due to Other Congest
already disappear and CSSR PS
JAJARSOLOMW improved

Conclusion
Conclusion
• Rejection due to Other Congest already disappear and CSSR PS JAJARSOLOMW
improved after to rebalance CPU Board Load of WBBP.
