Abstract: Parlay X is a set of Web Services interfaces for open access to network function. One of the alternatives for deployment of Parlay X functionality is an add-on to the Open Service Access (OSA) functionality. The OSA gateway is a special type of application server that translates the OSA interfaces in the network control protocols. The paper suggests a mapping of OSA Charging interfaces onto Diameter protocol messages. A formal approach to specification of OSA gateway behavior is suggested. The approach is based on the theory of Labeled Transition Systems and the concept of bisimilarity. Using the available mapping of Parlay X interfaces onto OSA interfaces, the possibilities of Parlay X charging control on sessions in all IP-based multimedia networks are investigated.
