    Abstract: Communication networks and methods are disclosed for providing converged prepaid charging and postpaid charging. A communication network described herein includes a switching system, a charging selection system, a prepaid charging system, and a postpaid charging system. When the switching system receives a call for a subscriber, the switching system processes a subscriber profile to determine a type of charging for the call. If the type of charging for the subscriber comprises a hybrid prepaid/postpaid charging, then the switching system transmits a query to the charging selection system. Responsive to the query, the charging selection system processes charging criteria to determine whether the hybrid prepaid/postpaid charging for the call should be prepaid or postpaid. The charging selection system initiates prepaid charging or postpaid charging for the call based on the charging criteria.
