CSSR PS degradation due to Other Congestion
(Huawei)

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

Analysis
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
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
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
Check UL Group at NodeB MML Command

Action
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
Check DL Group at NodeB MML Command

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.
