Parlay PAM in 3GPP's IP-Multimedia Subsystem

Open Access to Resource Management in Multimedia Networks

The paper is dedicated to mechanisms for open access to resource management in the Internet Protocol (IP) multimedia networks. First we present the concept of IP Multimedia Subsystem (IMS) and explain the IMS functional architecture, principles of quality of service management and service control in IMS. Then we describe the idea behind the opening of network interfaces for third parties so tha...

Service Delivery Platform Options for Next Generation Networks, approved within the national German 3G Beyond Testbed

The notion of next generation networks (NGN) is based on the convergence of fixed and mobile telecommunication networks and the internet towards an all-IP environment. These NGNs support the provision of integrated information and communication services in face of increasingly becoming more complex value chains, enabled by so-called service delivery platforms (SDPs). Therefore an NGN is an envi...

Open Service Access for QoS Control in Next Generation Networks - Improving the OSA/Parlay Connectivity Manager

The need for providing applications with practical, manageable access to feature-rich capabilities of telecommunications networks has resulted in standardization of the OSA/Parlay APIs and more recently the Parlay X Web Services. Connectivity Manager is an existing, ‘stable’ API for establishing QoS parameters in a network. However, it falls short as an interface to the expected requirements ba...

IP Multimedia Subsystems (IMS)

IP multimedia subsystem (IMS) represents a standardized next-generation reference system to provide an overlay global open service delivery platform (SDP) that enables provisioning of converged multimedia
