Abstract. For service providers online charging of composite services is necessary in order to manage financial risks of service delivery in multi-domain environments. At service level, inter-domain composite services consist of one or more service components, e.g. access service, IMS communication service or content service, delivered by different service providers. The 3rd Generation Partnership Project (3GPP) has developed a framework for off-line and online charging of IMS-based services. However, the current Online Charging System (OCS) specified by 3GPPP does not support an online charging function for composite services. The contribution of this work lies in the design of an online charging system that addresses the required charging functionalities based on the IMS online charging architecture. The design consists of a service composition information model guided by the NGOSS and SID concepts of the TeleManagement Forum, a set of functional charging system components and their interactions at their interfaces.

“…One of the major shortcomings of this charging model is the lack of supporting the exchange of service composition information to deal with charging of composite services through the so-called Ro-interface [Le09a]. The Charging Request interface and Charging Response interface solve this shortcoming.…”

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.
