An IN-based implementation of interactive video services

Abstract

Interactive video services will be among the first broadband services to be offered to residential and business customers. This paper describes a Full Service Network architecture based on the Intelligent Network (IN) which supports a large variety of services, including video on demand and other multimedia services. ATM will be deployed on an end-to-end basis, allowing standardised signalling protocols to be used. The target solution, however, requires special call and connection handling capabilities such as multi-connection calls and call transfer which are not covered by the current status of B-ISDN signalling protocols. Thuefore, we introduce an alternative solution which is based on current standards and allows an evolution from a fast prototype implementation towards our target concept.

A study of Specialized Resource Function mapping alternatives for Integrated IN/B-ISDN architectures

“…The purpose of this paper is to provide performance driven guidelines for the design of IN based broadband networks. Similar work has been performed in the framework of Signalling System No 7 (SS7) and B-ISON signalling protocols (Bafutto, 1994), (Lazar, 1994), (Veeraraghavan, 1995), (Veeraraghavan), (Willmann, 1990), (Xou, 1994), (La Porta, 1993) notwithstanding that in our case the integrated service facilities and the employment of IN capabilities necessitate more complex user-to-network and network-to-network transaction models (Hussmann, 1995). Our study undertakes issues related to the scalability of the IN broadband network by investigating and comparing alternatives for the mapping of SRF to physical entities.…”

“…A functional entity can be present in more than one physical entities but it cannot be split among multiple physical entities. In this paper we investigate alternatives for the mapping of IN functional to physical entities for the case of an integrated INIB-ISDN architecture (Hussmann, 1995), (Wu, 1995). The IN functional entities that participate in the exchange and process of the control information related to the request and provision of an IN service are the Call Control Function (CCF), the Service Switching Function (SSF) which identifies IN calls and triggers the service logic in the Service Control Function (SCF), the Specialized Resource Function (SRF) which manages the communication between the user and the IN, and the Service Data Function (SDF) containing service and call related data.…”

Rapid prototyping and fast user trial of multimedia broadcast and cellular services

“…Specialised rapid prototyping systems such as MediaBuilder platform fulfil this need for ATM services by offering rapid service creation and deployment through an extensible set of service components [6]. Service creation tools for intelligent networks used interactive visual programming for the composition of new services from service building blocks and the monitoring of their execution in the intelligent networks [7][8]. Rapid prototyping was also used to experiment with the options for TV-based services with interactive facilities [9].…”

Broadband multimedia services design and implementation exploiting IN features

“…Network Architecture for the provision of advanced multimedia servicesThis section describes a broadband IN-based network architecture[7][8], which can serve as a generic reference configuration for the provision of advanced multimedia services. This configuration is illustrated inFigure 1. where emphasis is given to the Broadband Intelligent Network (B-IN) modules (from this point on, the prefix B-will be added to the names of all functional and physical entities to indicate an extension of the original LN concept to broadband services).…”
