Do you know how to restrict location update of a inbound roamer in your network by LAC wise or service restriction by CELL wise???

The solution is required when you want to restrict LU of inbound roamer in border area to save unnecessary message transaction between your network and roaming partner network in that area. As most the cases found that the roaming is not allowed for those border subscribers. 

Here comes the solution.............

Enhanced Roaming Restriction by LAC::::::::::::::::::::::::::::

 

SET MAPACCFG: IFUSROAMR=YES;

MOD LAIGCI: GCI="<LAC>", MSCN="<MSCGT>", IFROAMANA=YES, LOCNONAME="border_A";

ADD LOCGRP: LOCNONAME="border_A", LOCGRPNAME="border";

MOD LAIGCI: GCI="<LAC>", MSCN="<MSCGT>", IFROAMANA=YES, LOCNONAME="border_B";

ADD LOCGRP: LOCNONAME="border_B", LOCGRPNAME="border";

ADD ROAMRESTGRP: SERVICETYPE=ENROAMRST, RSTRIBY=IMSI, BEGINNUM=K<RP_IMSI_prefix_start>, ENDNUM=K<RP_IMSI_prefix_end>, UGNAME="roamrest_imsi";

ADD USROAMRT: UGNAME="roamrest_imsi", LOCGRPNAME="border", ROAMREST=YES;

MOD MSFP: ID=P657, MODTYPE=P1, BIT=9, BITVAL=1;

 

 

Service restriction by CELL:::::::::::::::::::::::::

 

SET MAPACCFG: USRGRPSRCFUNCTION=YES;

MOD LAIGCI: GCI="<Global CELLID>", MSCN="<MSCGT>", IFROAMANA=YES, LOCNONAME="CELL_SMS_BLK";

ADD LOCGRP: LOCNONAME="CELL_SMS_BLK", LOCGRPNAME="CELL_SMS_BLK_GRP";

ADD ROAMRESTGRP: SERVICETYPE=ENROAMRST, RSTRIBY=IMSI, BEGINNUM=K<RP_IMSI_prefix_start>, ENDNUM=K<RP_IMSI_prefix_end>, UGNAME="SMS_BLK_IMSIGRP";

ADD USROAMRT: UGNAME="SMS_BLK_IMSIGRP", LOCGRPNAME="CELL_SMS_BLK_GRP", SRCPROHIBITSERVICE=SMMO-1&SMMT-1;
