gsm call flow for MS to SMS? and GSM call flow fro MS to
roaming MS?
Answer Posted / telecom_tester
GSM call flow from MS to roaming MS-
The MSC sends ISUP IAM to GMSC, GMSC analyses the dialled
digits and figure out which HLR to query and send "Send
Routing Information". HLR always knows the exact location of
mobile in the form of address of MSC/VLR.HLR sends "provide
roaming number" asking MSRN(Mobile Station Routing Number).
MSC-serving provides the MSRN in return message and HLR
forwards it to GMSC which inturn sends IAM to MSC-S.
