Hi Hari,
Thanks Buddy…But not yet completed..
“1.I want to know more specifically how VMSC forwards this USSD to HLR ?
The MS-initiated USSDReq includes IMSI, which will be used to forward the USSDReq to HLR.”
For this what will be the calling number in MAP-Query Message.
1.HLR address from VLR DB ?
