Abstract: An Online Charging System (“OCS”) for charging a data session of a subscriber, in response to a request to initiate the data session provides a first granted service units of data for the data session. During the data session, the OCS receives a change in charging conditions for the subscriber and, in response to the change, sends a re-authorization message to the subscriber. In response to the re-authorization message, the OCS receives from the subscriber a first update message that includes a used service units for the data session since the previous update message. In response to the update message, and based on the change in charging conditions and the used service units, the OCS then provides a second granted service units of data for the data session.

Abstract: A framework is disclosed which enables a management system to manage completely different type of network elements (NEs) running different versions of their embedded software by introducing generic operational interfaces, generic data interfaces, information descriptors and self adaptive control mechanism. This Management system framework consists of mainly two parts a) core application and b) element-dependent components and c) a set of generic interfaces. When the management system is launched, it executes the core application. The core application comprises of network element independent version independent generic functionalities that can be used to interact with a variety of network elements and a dynamic control mechanism to make selection and placement of pluggable components at appropriate time and place during execution.
