CSSR PS degradation due to Other Congestion (Huawei) [email protected] [email protected] [email protected] Main Problem Highlight : Site JAJARSOLOMW all sectors, have degradation of CSSR PS, follow by increments of Other Congestion Nexwave Design and Strategic Page 2 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 Nexwave Design and Strategic Page 3 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 Page 4 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 Nexwave Design and Strategic Page 5 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 Nexwave Design and Strategic Page 6 Result Highlight : • CPU WBBP Board Load already balanced • Rejection due to Other Congest already disappear and CSSR PS JAJARSOLOMW improved Nexwave Design and Strategic Page 7 Conclusion Conclusion • Rejection due to Other Congest already disappear and CSSR PS JAJARSOLOMW improved after to rebalance CPU Board Load of WBBP.
