WorkFlow of Billing Process The gsmSCF


I have a question regarding billing procedure in SS7 network.

How do the GSM Service Control Function (gsm-SCF) make a billing process to charge for a phone call (voice call) in the GSM Service Switching Function (gsm-SSF)?

I mean the work flow of billing procedure in the gsm-SCF.

Please help me out.
Any response will be greatly appreciated.

I look forward to hearing from you.
Thank You.


The billing procedure is managed by interactions between the SSF and SCF.

Do you mean the call flows within the SCF or are you referring to the call flow within the ss7 network, i.e how the SCF and SSF work together to control the call set up and billing for the voice call?
