    Competitive market conditions and narrowing profit margins are driving network operators to optimize their network and to find new sources of revenue. The first step of this optimization is to use one common packet network for voice, video and data traffic. In these networks SoftSwitches handle the voice and multimedia calls and control the media gateways to interface the packet network to the PSTN/ISDN networks View full abstract»

    The last decade has seen a significant move towards the combining of the telecommunications and commercial computing and data networking markets and products. With the enormous growth in the use of the Internet and the potential of offering telecommunications services using Internet technologies, the world's suppliers of telecommunications equipment are facing a monumental shift in the market place for their products. The potential to re-use existing products needs to be explored in order to gain maximum benefit from development investment. Network intelligence platforms appear to offer a real opportunity, at first sight any rate, for re-use in a packet-switched world. The aim, in both cases, is to enable new, innovative services to be developed rapidly, using easy to use programming interfaces, and for these services to be easily and rapidly deployed in a secure, reliable and managed environment. This presentation compares the two worlds at the level of network intelligence, identifying the common themes between the two worlds, the potential for re-using/modifying TDM-based products in the packet-switched environment, and the problems associated with this View full abstract»

  • The use of semaphores with feature interactions in next generation networks

    Page(s): 41 - 49
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (476 KB)  

    In next-generation networks, features may be provided from various venues, expanding the boundaries of where features are provided. The basis of this proposal is that the coordination of feature interactions in NGN could be served well with the use of semaphores. A feature semaphore is associated with each zone of a call session, and these semaphores become part of the user's per call data. This paper explores how feature interactions could be controlled using these concepts in lieu of the current circuit-based method of triggers and feature precedence rules View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1528 KB) |  | HTML iconHTML  

    3G networks promise a world of new applications. To make 3G a profitable business, these have to be billed. The classical billing process is in danger of collapse under the exploding load of tickets and log files to be processed. The IN based charging model, as currently used for pre-paid solutions, is much more efficient since it was designed for a real-time process. The article compares both processes with respect to projected developments in the communications market and user behaviour. It gives an outlook on what a unified billing process might look like and why it best fits to what the new world of mobile Internet is going to bring us View full abstract»

    With the explosive growth in internetworking, managing such an environment is more difficult than before. Traditional network management technology can suffer from the problems of poor scalability and single point of failure. In order to overcome these shortcomings, a multilayer architecture for network management with a unified management interface is promising. Moreover, the emerging mobile agent technology represents a promising approach to provide dynamic features of management functions. This paper presents a three-layer dynamic network management architecture with mobile agents. Based on the proposed architecture, system information and an agent-based monitoring application are reported View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (620 KB)  

    The current evolution of e-commerce is driven by a large variety of applications accessed by means of different devices. A missing piece in the game still is a generally accepted payment system that can meet the requirements of all the new and upcoming scenarios. The article discusses whether this is feasible at all. Instead, the existing systems, that proved well for certain applications, could be unified by an adaptation layer. The core requirements of such an adaptation layer, functional as well as qualitative, can well be met by typical intelligent network systems. They could also bring additional value added features into such an e-commerce enabling service that are not limited to pure payment View full abstract»

    It is expected that the TINA architecture will play an important role in providing innovative services in the future. However, the customer has to install the DPE in his terminal devices while accessing these services, since all TINA services have to run on top of the DPE. We present a framework for accessing the TINA platform with WAP, which can relieve the customer of installing the DPE in his terminal devices. In addition, the Dutch service implemented under this framework is elaborated View full abstract»

    The desire within the telecommunications world for new and faster business growth has been a major drive towards the development of open network API. Over the past 7 years several (semi) standardization groups have announced work on network API, including TINA-C, JAIN, IEEE P1520, INforum, 3GPP, JAIN, Parlay. The Parlay group seems most successful in attracting industry awareness with their API, called the Parlay API. The rational behind the Parlay API is that it attracts innovation from third parties that are outside the network operator's domain to build and deploy new network-hosted applications. This also means that the public telecommunication network is opened for niche and short-lived applications as well as for applications that possibly integrate telephones with other terminals such as PC. The Parlay group has successfully passed the first two phases of success, namely publishing their API on the right moment in time and attracting a critical mass within the telecommunication industry with their results. Prototyping the API on a real network execution platform is the only way to show its technical feasibility. Such an exercise was executed internally within Lucent Technologies and raised a number of questions as well as recommendations on both the technical and the semantical behavior for systems that will be interconnected via the Parlay API. We share these results, showing the drawbacks and advantages as well as challenges for this API View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (376 KB) |  | HTML iconHTML  

    This paper presents a novel service, which is aiming at assisting the end-user in the management of his electronic devices. Nowadays the user is confronted with several different communications devices as, for example, a plain-old telephone, a mobile telephone, a cordless telephone, and a PC or a workstation which acts as a multimedia terminal. All these devices are autonomous and function independently of each other and without any coordination. In fact they are even not aware of the presence of other devices. As the owner the user is required to handle them all and does not always succeed since as a human being he cannot perform many tasks at the same time. This paper describes in detail the functions of the Device Management Service (DMS) with use cases. Each use case is examined carefully with several implementation alternatives. The technologies required for each alternative are also identified View full abstract»

  • PILOTE: a service creation environment in next generation networks

    Page(s): 36 - 40
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (80 KB) |  | HTML iconHTML  

    We introduce a reference workbench architecture for UML (Unified Modeling Language)-based service creation founded on the decoupling of dynamic (process) and static (profile) aspects. This workbench has been developed in the PILOTE project (Processus d'Ingenierie du Logiciel des Telecommunications) of the French RNRT (Reseau National de Recherche en Telecommunications). A fairly high integration level among the tools of the workbench have been reached using metamodeling techniques (OMG standards MOF, XMI). This paper provides an example of a service creation environment in next-generation networks through a specification of the pre-paid calling card service. These INCM-compliant service creation processes and profiles, being exported to a repository, are now easily re-usable. Considering these aspects and the obtained results, the PILOTE toolset seems to be a good environment for service creation in next-generation networks View full abstract»

    Current telecommunications networks are vertically integrated and operate within simple business models. Convergence of services requires the support of multiservice networks, the so-called next generation networks. Telcos planning and implementing new services have to formulate business plans and evaluate technology for the multiservice network. This paper presents a systematic approach to information handling, modelling and utilization to support a holistic assessment of technologies in the light of business requirements. A telecom map is proposed which addresses the concerns of functionality, relationships, implementation constraints and business considerations. The map is placed in a framework, and has three associated representations: domains, information relationships and the evaluation process View full abstract»

    Since the implementation of the very first intelligent network platforms in the USA in the 1980s and in Europe in the early 1990s, manufacturers invested much effort and allocated many resources to develop and to support service-independent building block (SIB)-based service design tools, and thus to comply with ITU-T, ETSI CS-x and Bellcore standards. Siemens will introduce and market in 2001 a new version of its IN product under the brand name @vantage. Among the numerous innovations a service feature concept will revolutionize service creation processes. The objective of this new service feature concept is to replace regular SIB-based service implementations by reproducing those SIB functionalities on a higher level. The service feature concept will allow us to cut back costs in service development and test, reduce time to market by speeding up the service creation process through all phases and enhance service quality View full abstract»

    This document describes the objectives of the Intelligent Network Forum. The IN Forum has adopted a new working method, which involves issuing requests for information (RFI) to both members and other industry bodies. The first RFI asked for views on the evolving architectures for the delivery of services and applications in next generation networks. It also seeks views on how respondents propose to best develop specific classes of service using the chosen architectures. The RFI was issued to gather information on the following services: multi-party conferencing; personalised number service; voice and data virtual private network (VPN). The results of the IN Forum RFI presented at the workshop were not available when this submission was published View full abstract»

    This presentation is about charging for content or application usage. We propose a new API (application programming interface) that allows content servers or application hosts to delegate the charging process to a payment service provider. The new API: 1) does not depend on the type of the application to be charged, 2) does not care about when and how the customer is billed, 3) is able to support prepaid as well as postpaid customers, and 4) is designed to be carried by the public Internet View full abstract»

    We know that the deregulation process and the market opening are very important issues in today's telecom life. The process has been different in each continent. The scope of this study does not cover the whole world, but the study is made from the Latin America point of view, especially Mexico. There has been a trend in which advanced services are the differentiating factors and play a key role in a service provider's success. Examples of these advanced services are card calling, split charging, and toll-free calling. Their implementation was initially embedded in switching software, which hindered fast deployment of new services. The intelligent network architectural framework was born in the 1980s as a remedy. Its goal is to allow the rapid and uniform creation and management of advanced telecommunications services. The intelligent network (IN) concept relies on the separation of call control and service control to ease the deployment of new services. These new services do not need to be wireline services, in fact the future points out that wireless services will be the most demanded ones. In this paper, we first indicate the overall scope in the Latin America intelligent network infrastructure through an examination of the telecom market in Latin America. Then we discuss the difficulties faced by carriers in the deployment of advanced wireless services. Finally, we present a proposed architecture for the deployment of advanced IN services in the Latin America telecommunications market View full abstract»
