SMS Online Charging - SCP charges or Reserves the amount ...

Hi

I need to know how the SMS online charging is done. when MSC/SSP sends IDP to SCP for charging,does SCP deduct the amount at the same time and then sends"continue" to MSC/SSP to proceed with the message transfer to SMSC OR after getting the charge request from MSC ,SCP looks at the subscriber balance and instead of deducting the amount ,SCP only reserves the amount and then wait for Confirmation from SMSC of actual delivery of SMS to B-Party before deducting/charging the amount to A-party ?

Please share your views. If both scenarios re true what's most widely opted solution?

Hi,

When GSMSSF (SSP) sends IDP-SMS to the GSMSCF (SCP) the SCP will peform credit check and it will reserve the credit for the transaction. If credit is not available it will deny the SMSC-Submit, where as if credit is available then the MSC submits the SMS to the SMSC. Once after the successful submit to SMSC the GSMSSF will send the Event report SMS (ERB-SMS) with O_SMS_Submitted with which the SCF will instruct to deduct the reserved credit. If the submit is failed to the SMSC then the GSMSSF will send the Event Report SMS (ERB-SMS) with O_SMS_Failure with which the GSMSSF will release the reserved credit.

I hope it is clear. Please let me know in case of any further clarifications.
