Abstract
A method and system for processing a prepaid call in a mobile telecommunications network wherein charges can be recovered for the call after the SCP and Prepaid Platform lose contact with the MSC or GMSC handling the call. A Trigger Detection Point known as 'O-Disconnect' or 'T-Disconnect' can be armed in a prepaid subscriber's HLR and can be triggered when the MSC/GMSC loses contact with the SCP. The MSC/GMSC can record the time that the TDP was triggered in memory. The MSC/GMSC can then monitor for call disconnect and record the disconnection time in memory. When the call is disconnected the MSC/GMSC can renew contact with the SCP. MSC/GMSC can identify the call using a unique call identifier and advise the SCP of the times at which contact was lost and the call was disconnected. The SCP can use this information to calculate a charge for the portion of the call that occurred after contact with the MSC/GMSC was lost so that the entire call can be charged in near real-time.
