“…In the computational viewpoint (Chapter 7), the service composition is persisted in the Charge Aggregator. This component uses service composition to actually correlate and merge the charges of the same service session [Le09b]. Hence, this requirement is satisfied by the proposed billing system.…”

SUMMARY Modern charging systems routinely apply the user, network, and service‐related information while performing online charging. Compared, however, to all the information available to and used in managing the network as a whole, the charging systems only use a limited subset. This work is motivated by the challenge to identify which information is used, and how it is used in online charging‐related processes, and also to explore whether it could be utilized ‘better’ or ‘smarter’ to improve future online charging systems functionality. We do not attempt to predict which information will be utilized in such systems and for what purpose, but instead summarize the open issues in view of the emerging trend of exploiting the user, network and service‐related information in service provisioning. We focus on the most recent 3GPP standards and relevant research papers, and propose three key aspects of online charging, with respect to information utilization: (a) signaling aspect, (b) inter‐domain aspect, and (c) service‐ and component‐based aspect. We present a state‐of‐the‐art review by grouping the works found in the literature based on the aspects they are associated with, and compare them based on the proposed comparison criteria. The discussion presented at the end of the paper indicates three common open issues, namely: (1) lack of common charging information specification and structure; (2) lack of mechanisms for information sharing among stakeholders in the service delivery process; and (3) lack of a common framework for sharing information while protecting user privacy.
