In this paper we suggest an approach to quality of service based charging in Internet protocol multimedia subsystem (IMS) by the use of Parlay X Web services. The policy and charging control (PCC) functions are analyzed and their support by Parlay X interfaces is evaluated. The open access to application-driven quality of service and payment functions is investigated and mapped onto IMS control protocols...
The paper investigates capabilities of Parlay/OSA (open service access) applications to access to call-unrelated functions, like mobility, user status, terminal capabilities, presence and availability in SIP (Session Initiation Protocol) networks. It addresses means to support Parlay/OSA applications from SIP endpoints in the context of non-INVITE server transactions and client transactions. A mapping...
A new mark-up approach to next generation service creation is proposed. The service logic is composed by linking high level components written in service logic processing language (SLPL). SLPL is a mark-up language that exploits Parlay/OSA application programming interfaces. The SLPL components represent common functionality that can be reused in different applications.
In this paper we present a new XML based language for service logic processing (SLPL). SLPL supports OSA (open service access) interfaces allowing service logic scripts to execute both on call-related and call-unrelated events. A formal grammar definition for a couple of processing nodes is given. An example of OSA application is considered
