WEB SERVICES IN TELECOMMUNICATIONS - ORCHESTRATION IN WEB SERVICES AND REAL-TIME COMMUNICATIONS - Web services orchestration is now being adopted for the coordination of real-time communications services, including telephony, video and multimedia communications. But do these communications services integrate into workflows in the same way as Web services in the data environment, and are orchestration mechanisms for Web services sufficient for the needs of workflows that involve real-time communications?

WEB SERVICES IN TELECOMMUNICATIONS - A SURVEY OF WEB SERVICES IN TELECOMMUNICATIONS - The authors present a survey of service-oriented architecture and Web services within telecommunications. Telecommunications over the past few years has been in a state of constant flux, with shifts in regulations, increased competition, and technological progress. The article describes these forces in detail and shows that the need for successful adoption of SOA within telecommunication has become a major agenda item for the majority of telecommunication network operators. The article then proceeds to describe SOA and its key enablers in telecommunications -- Web services, event-driven architectures, Parlay X-ECMA specifications, and the enterprise service bus.Griffin, Donna et al. | 2007

WEB SERVICES IN TELECOMMUNICATIONS - A BUSINESS MODEL FOR DYNAMIC COMPOSITION OF TELECOMMUNICATION WEB SERVICES - Web service composition is a mechanism for creating new Web services from existing Web services. Web service composition enables rapid service creation by reusing existing services. Dynamic composition is composition at runtime. A business model defines the different parties involved in service provisioning and their relationships. However, the existing business models are not suitable for Web service composition. This article proposes a novel business model for dynamic Web service composition that is an extension of the standard Web service business model.Karunamurthy, Rajesh et al. | 2007

WEB SERVICES IN TELECOMMUNICATIONS - COMPOSABLE MEDIATION FOR SECURITY-AWARE MOBILE SERVICES - The authors show how service mediation can be used to add security features to services in a mobile service platform. This base platform takes care of security, charging, and other basic functions, which are then configured for services at runtime using a pluggable mediator framework.Tarkoma, Sasu et al. | 2007

IP MULTIMEDIA SYSTEMS INFRASTRUCTURE AND SERVICES -- PART II - IMS FOR ENTERPRISES - The authors discuss how the IMS architecture is applicable to the enterprise environment, the relevance it has for enterprise users, different options for integrating private and public IMS infrastructures, and the impact of those options on enterprises and IMS service providers. They review IMS architecture, discuss the requirements of enterprise communications systems, and present four possible architectures for the use of IMS by enterprises.Khlifi, Hechmi et al. | 2007

IP MULTIMEDIA SYSTEMS INFRASTRUCTURE AND SERVICES -- PART II - THE OPERATOR'S RESPONSE TO P2P SERVICE DEMAND - Peer-to-peer (P2P) systems are in high demand for all sorts of tasks -- Video communication, resource sharing, and content retrieval, to mention a few. However, current P2P solutions are intrinsically incompatible with the IP multimedia subsystem (IMS), the service provisioning framework adopted by the major telecommunication players. The authors look at ways to develop P2P applications over IMS, identifying the essential service components that pave the way toward interoperable P2P.Liotta, Antonio et al. | 2007

IP MULTIMEDIA SYSTEMS INFRASTRUCTURE AND SERVICES -- PART II - NETCAPE: ENABLING SEAMLESS IMS SERVICE DELIVERY ACROSS HETEROGENEOUS MOBILE NETWORKS - An evolving wireless world is constantly providing users with a wider set of access technologies to choose from, each with different capabilities and properties. In this world, IMS as defined by 3GPP provides an enabling, standardized multimedia architecture that is access independent, hence, providing service convergence.Udugama, Asanga et al. | 2007

IP MULTIMEDIA SYSTEMS INFRASTRUCTURE AND SERVICES -- PART II - CHARGING IN THE IP MULTIMEDIA SUBSYSTEM: A TUTORIAL - The IP multimedia subsystem enables a service-rich communication landscape and the convergence of mobile and fixed networks. However, IMS solutions can succeed only when charging for these new services is supported in a flexible and efficient manner. To meet the new challenges, the 3GPP recently introduced a generic charging framework. The authors give a short overview of the 3GPP charging framework and then describe how IMS charging works within this framework. To illustrate IMS charging, they discuss an IMS scenario in which three persons with different payment methods conduct a teleconference.Kühne, Ralph et al. | 2007

IP MULTIMEDIA SYSTEMS INFRASTRUCTURE AND SERVICES -- PART II - THE THREAT OF UNSOLICITED SESSIONS IN THE 3GPP IP MULTIMEDIA SUBSYSTEM - Unsolicited voice and video calls are highly disruptive, causing frustration to end users, and they are wasteful of network resources. These communications also may involve fraud, phishing, or the propagation of offensive material. This article highlights the scale of this inevitable problem and proposes mechanisms to enable users to filter their incoming multimedia sessions, such that only legitimate calls are received.Waiting, David et al. | 2007

IP MULTIMEDIA SYSTEMS INFRASTRUCTURE AND SERVICES -- PART II - APPLICATION-LEVEL QOS NEGOTIATION AND SIGNALING FOR ADVANCED MULTIMEDIA SERVICES IN THE IMS - To support novel media-rich applications across a wide range of user devices and access networks, IMS must support negotiable quality of service (QoS) for IP multimedia sessions. The authors describe the application-level QoS signaling as specified by the 3GPP and propose some enhancements based on advanced QoS parameter matching and optimization functionality to be included along the signaling path.Skorin-Kapov, Lea et al. | 2007

IP MULTIMEDIA SYSTEMS INFRASTRUCTURE AND SERVICES -- PART II - MOBILITY TESTBED FOR 3GPP2-BASED MMD NETWORKS - Wireless service providers strive to preserve the quality of service and user experience for mobile users. Several standards bodies are defining architectures that can be used as a platform to provide secure and seamless services to these mobile users. These architectures aim to provide several required functions such as signaling, configuration, security association, encryption, and billing. However, the placement of several functional components and their interaction at several layers contributes to the operational complexity and thus affects the optimal results.Dutta, Ashutosh et al. | 2007

IP MULTIMEDIA SYSTEMS INFRASTRUCTURE AND SERVICES -- PART II - EXPERIENCE WITH AN IP MULTIMEDIA SYSTEM TRIAL FOR PSTN MIGRATION - The authors share our experience of a trial that attempted to gain practical experience in migrating telephony services from the public service telephone network (PSTN) to the IP multimedia system (IMS) domain. They point out some key challenges on the migration path to IMS and identify many issues for successful service deployment in an IMS-based next generation network. Some regulatory concerns and non-technical issues also are addressed.Chiou, Hong-Bin et al. | 2007
