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

RNC and Nodeb Hardware & Software Version :

Network Equipment Current Version

RNC BSC6900 UO UMTS V900R013ENGC00SPH552

NodeB DBS3900/BTS3900/BTS3900A/BTS3900L WCDMA V200R013C00SPC339

Network Topology :

Technical Implementation: Site Hardware Fallback Data Configuration Fallback Nodeb Hardware Dismantle Overview

Site Hardware Fallback :

Site Hardware Fallback Qty

1 Jumper cross connection 3

2 Dismantle inter-RFU RF signal cable 6

3 Dismantle WRFU 3

4 Dismantle CPRI cable 3

5 Dismantle WBBP 1

Data Configuration Fallback :

Data Configuration Fallback NE Remark

1. Remove HCPT cell RNC RF

2. Remove HCPT IPPath RNC Iub dedicated

3. Remove HCPT logic port RNC Iub dedicated

4. Remove HCPT local cell NodeB RF

5. Remove HCPT RRUCHAIN NodeB RF

6. Remove HCPT WRFU NodeB RF

7. Remove HCPT ULGROUP/DLGROUP NodeB RF

8. Modify RX mode NodeB RF

9. Remove HCPT IPPath NodeB Iub dedicated

10. Remove HCPT RSCGRP NodeB Iub dedicated

11. Remove HCPT Dev IP NodeB Iub dedicated

Nodeb Hardware Dismantle Overview :

2 Network impact for RAN Sharing Fallback

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.

4..3 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;



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 RRUCHAIN: RCN=xxx;



Step 3 List and Remove ULgroup/DLgroup and WBBP board HCPT based on topology above (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; //--WBBP board for HCPT

Step 4 Modify RX mode (Reconfigure XL Axiata RX mode) (Noted: Before Modify list first and backup all information as attached below)

Lst Locell and Sector nodeb ran sharing.txt

// Remove XL Cell to Configure antenna Sector

LST LOCELL: MODE=LOCALCELL, LOCELL=xxx

RMV LOCELL:LOCELL=1;






LST SEC: STN=xxx, SECN=xxx

RMV SEC: STN=xxx, SECN=0;



// Reconfigure XL antenna Sector

ADD SEC: STN=xxx, SECN=0, SECT=LOCAL_SECTOR, ANTM=2, RFINTERCONN=FALSE, ANT1CN=1,

ANT1SRN=4, ANT1N=N0A, ANT2CN=1, ANT2SRN=4, ANT2N=N0B;





// Reconfigure XL locall cell ADD LOCELL: LOCELL=1, STN=xxx, SECN=0, SECT=LOCAL_SECTOR, TTW=FALSE, CN1=1, SRN1=4,

SN1=0, ULFREQ=9813, DLFREQ=10763, MXPWR=460, HISPM=FALSE, RMTCM=FALSE, VAM=FALSE;

ADD LOCELL: LOCELL=2, STN=xxx, SECN=1, SECT=LOCAL_SECTOR, TTW=FALSE, CN1=1, SRN1=4,










Step 5 Remove HCPT IPPATH LST IPPATH:;

RMV IPPATH: PATHID=xxx;



Step 6 Remove HCPT RSCGRP ID LST RSCGRP:;

RMV RSCGRP: SRN=0, SN=7, BEAR=IPV4, SBT=BASE_BOARD, PT=ETH, PN=0, RSCGRPID=1;

Step 7 Remove HCPT Device IP & IP route LST DEVIP:;

LST IPRT:;

RMV IPRT: SN=7, SBT=BASE_BOARD, DSTIP="x.x.x.x", DSTMASK="x.x.x.x", RTTYPE=NEXTHOP,

NEXTHOP="x.x.x.x";

RMV DEVIP: SN=7, SBT=BASE_BOARD, PT=ETH, PN=0, IP="x.x.x.x";

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)
