SCN Call Control Message call in SCN Call Control Message call in SetupSetup
On completion of this module, you should be able to:
• Describe the main task performed by MSS and MGW software’s
• Describe external signalling message triggering MSS and MGW software action
• Analyse Process message flow in MSS and MGW when UE call setup occour
• Analyse selected messages from call setup using the given references

MSS Call phases
• Phase-1: From the beginning of the call setup till the moment the signalling process sends the first message to
ICC
• Phase-2: From the first message to ICC till the start of digit analysis
• Phase-3: From the digit analysis till the first message to OCC
• Phase-4: From the first message to OCC till the establishment of speech connection
• Phase-5: Clearing of the call
