RAN Sharing Fallback (XL-HCPT) 1
SUMMARY
Iub re-configuration in RNC and NodeB side, we have to main scenario like below : 1. Scenario for site which has been configured as RAN Sharing Mode (144 nodeb) 2. Scenario for site which has been installed but not configured yet as RAN Sharing site

Network impact for RAN Sharing Fallback
3 3..1
Remove HCPT Cell. RNC IPPath HCPT should be removed. Remove HCPT Logic Port. Remove HCPT Locell. Modify RX mode. NodeB IPPath HCPT should be removed. NodeB service would be down about 15 minutes. It only impacts one site service.
RNC SIDE CONFIGURATION
Objective To Fallback RNC RAN sharing configuration at RNC side

Procedure and Work Flow
Step 1 List Locell HCPT & Remove Locell HCPT Nodeb side (noted: HCPT used this frequency for ULFREQ=9613, DLFREQ=10563)
LST LOCELL: MODE=ALLLOCALCELL; RMV LOCELL: LOCELL=xxx; RMV LOCELL: LOCELL=xxx; RMV LOCELL: LOCELL=xxx;
Step 2
List and Remove RRU , RRU Chain HCPT based on topology above
(Noted: before remove RRU and RRUchain make sure check cpri cable which is connected from WRFU to WBBP, usually HCPT used wrfu board at slot 1, 3, 5 and wbbp board slot 2) LST RRU:; LST RRUCHAIN:; RMV RRU: CN=xxx, SRN=xxx, SN=xxx RMV RRU: CN=xxx, SRN=xxx, SN=xxx RMV RRU: CN=xxx, SRN=xxx, SN=xxx
RMV RRUCHAIN: RCN=xxx; RMV RRUCHAIN: RCN=xxx; RMV RRUCHAIN: RCN=xxx;
Step 3 above
List and Remove ULgroup/DLgroup and WBBP board HCPT based on topology
(Noted: HPCT usually used DLgoup and ULgroup no 1 & WBBP board at slot 2, before remove this board make sure there are cpri cable connected to WRFU board for HCPT board allocation)
LST DLGROUP: DLGROUPN=xxx; LST ULGROUP: ULGROUPN=xxx; RMV DLGROUP: DLGROUPN=1; RMV ULGROUP: ULGROUPN=1; DSP BRD:; RMV BRD: SN=xxx;
Step 4
//--WBBP board for HCPT
Modify RX mode (Reconfigure XL Axiata RX mode)
(Noted: Before Modify list first and backup all information as attached below)

Step 5
Remove HCPT IPPATH
LST IPPATH:; RMV IPPATH: PATHID=xxx; RMV IPPATH: PATHID=xxx; RMV IPPATH: PATHID=xxx;
Step 6
Remove HCPT RSCGRP ID

Step 8
Active Cell From RNC side
(Note: activate cell when NodeB configuration done) ACT UCELL: CellId=xxx;
5. ROLL BACK EXECUTION
RNC SIDE Step 1. Add HCPT cell Step 2. Add IPPATH HCPT Step 3. Add IP Logical Port HCPT
NodeB SIDE Step 1. Reload the backup .xml script
6. Testing after operation It needs XL team to verify service after operation in Surabaya.
7. KPI monitor and CPU load monitor on M2000 a.
Monitor after operation:
// KPI monitor and CPU load monitor. // check alarms which should be compared with the alarms before operation. // Verify the service through LMT
b.
Monitor at first Busy Hour after operation:
// KPI monitor
8. Operation time Maintenance time window. (00:00 until 04:00 am)
