Patent ID: 8386351

Claim:
Method of executing a real-time charging session in a charging system being interfaced to at least one communication network, comprising the steps: initiating, using a processor, a fund reservation with respect to at least two service types used for a single service; and reserving, using the processor, funds for service delivery to the at least two service types in parallel using a predetermined fund splitting optimization to minimize deviations between time of predicted fund depletion for the at least two service types, wherein the predetermined fund spitting optimization is executed using preregistered information on the amount of preferred funds and minimum funds with respect to each involved service and related service types, or the predetermined fund splitting optimization is executed with respect to a pre-known combination of services and related service types and uses a splitting mechanism integrated into a rating service activated by the charging system, or the predetermined fund splitting optimization is executed in an adaptive manner on the basis of historical use data reflecting prior usage with respect to each involved service and related service types.
