MSCID&ROAMING/HANDOVER NUMBER CHANGE PROCEDURE

According to VoIP network configuration requirement, all roaming/handover number has to be changed to identity VoIP adapted, and related MSCID to be changed in same way. Below is brief procedure for MSCID/ROAMING NUMBER change procedure for all related NE.
A key key point is:All related NE must modify data correctly for target MSC before cutover.


1.Modify DT inown MSC

ANBCI;
ANBSI:……(B number analsys,terminate in own msc for roaming number)
ANBAI;
C7GZI;
C7GSI:……(G number ,terminate in own MSC)
C7TAI;

2.Modifyfor related Ericsson NE

MSC/TMSC
ANBCI;
ANBSI:……(roaming number to target MSC)
ANBAI;
MSC/HLR/STP/SCP
C7GCI;
C7GSI:……(G number to taget MSC)
C7TAI;

3.ModifyDT in other releted non Ericsson NE,Both for MSCID and ROAMING NUMBER

4.Lifeline test for own MSC

5.Cutover(to be done at low traffic hour).

Define new roaming/handover number(1344…) in own MSC,
EXNSI:……
MGRSI:……
MGRSC:……
MGRNI:……
From now both 2 sets of MSRN are working!

Change MSCID in own MSC:
MGCAC:……


Change SSF_SERVICE_TRIGGER_ORIGINATION in own MSC:
DBTRI
BTSC:TAB=SHTSO,OGLT=861344xxxx……
DBTRE:COM;

Change AXE parameter PRESSUBDATAM
DBTRI
DBTSC:TAB=AXEPARS,NAME=GSMMDSC,SENTAME=PRESSUBDATAM,VALUE=0;
DBTRE;

Order large restart to force all subscr. re-regesiter
SYREI:RANK=LARGE,EXPL=…;

Charging center:
Modify new MSCID for target MSC

6.Delete old data for old ROAMING/HANDOVER number in own MSC(also old MSRN
can be delete few days later,depend on customer)
MGRNE:……;
MGRSE:…..’
EXNUE……;

Change PRESSUBDATAM back
DBTRI
DBTSC:TAB=AXEPARS,NAME=GSMMDSC,SENTAME=PRESSUBDATAM,VALUE=1;;
DBTRE

7.Fallback

If there is serious problem can not be solved in time after cutover,MSCID&ROAIING NUMBER is to be changed back

Delete new roaming/handover number,only old MSRN left.
MGRNE:……;
MGRSE:…..’
EXNUE……;

Change MSCID back
MGCAC….;

Change SSF_SERVICE_TRIGGER_ORIGINATION back in own MSC

DBTRI
BTSC:TAB=SHTSO,OGLT=861390/861374xxxx……
DBTRE:COM;


Order large restart to force all subscr. re-regesiter
SYREI:RANK=LARGE,EXPL=…;

Charging center:
Modify MSCIDback for target MSC
