How to achieve accurate and fair benefit sharing amongst service providers is a key issue in the sustainable development of SOA-based operating platforms. The realisation of this goal necessitates an efficient, flexible, and scalable service charging solution. Charging for composite services is more complex than that for traditional services because in the former, more factors including the sub-services provided by different providers, service exceptions, and sub-service updating are considered. This paper presents a rule-based charging method for composite services. Chained composite service and network-like composite service based on abstract charging actions are proposed. Through these services, the charging state diagram and charging cycle management in the charging service caller layer are achieved. Exception handling and recovery solutions are also discussed, along with the support of the rule engine transaction in the charging service implementation layer. The experiment shows that the proposed charging system can fulfil the requirements of charging services.
