This paper discusses the design and implementation of blended servicescomposite services whose base component services interact within a common control structure. The paper focuses on blended services that combine aspects of Internet Protocol television (IPTV) and IP Multimedia Subsystem-(IMS)-based telephony services and, in particular, focuses on a service that blends TV viewing and telephone call-handling functions. If a subscriber to this service receives a telephone call while watching TV, the caller ID is displayed on the subscriber's TV screen and the subscriber can signal call control instructions using the set-top box remote control. In this service blend, functions from each base service are coordinated with actions in the other. The mechanism allowing this service is an information channel that allows status and control information to move between the subscriber's set-top box and the IMS system. The services described in this paper are built upon a software foundation called the Alcatel-Lucent Service Broker™ platform, a platform that has unique capabilities to support such an information channel and to serve as the gateway between IMS and digital TV. This foundation offers service developers a set of important functions for the creation of blended services. Specifically, the Alcatel-Lucent Service Broker offers a means of controlling the invocation of base services, a means of communicating through different protocols, and support for large-scale deployment and for service customization. © 2007 Alcatel-Lucent. them, and generating new revenue is to offer customers attractive new services. These advanced services are typically created by bundling or blending existing services.Bundled services are created by associating basic services into a single service offer through a common billing plan or through combined service data.

The 3rd Generation Partnership Project (3GPP) IP Multimedia Subsystem (IMS) standards provide a core telecommunications network architecture that promises high flexibility in the creation of new and blended services. This stems primarily from two aspects: access independence and the highly flexible, extensible Session Initiation Protocol (SIP). Lucent Technologies' Service Enhancement Layer provides a suite of standards‐compliant tools and technologies that can work in and above the IMS core, allowing service providers to realize the full potential of IMS in a cost‐effective manner. These enablers are, at a fundamental level, carrier‐grade middleware that can reside on the most appropriate hardware platform. The three most important components of this layer are the Lucent Service Broker™ application, which enables blending of IMS services without having to modify the application servers; the Unified Subscriber Data Server, which provides a comprehensive approach to managing subscriber profile data regardless of where it is sourced; and the Lucent Vortex™ policy management infrastructure, which provides a high‐speed rules engine suitable for personalization and flexible network optimizations. This layer, which also includes other components such as the presence server, can grow to include additional components. The Active PhoneBook application, which includes both server‐side and client‐side components, is useful as a hub for providing blended services to end users. © 2006 Lucent Technologies Inc.

BT has embarked on an ambitious and innovative programme to replace its current core network with an all-IP next generation network (NGN) known as 21CN. One of the important properties of an NGN is to allow new and innovative services to be created and deployed quickly, easily and cost effectively. However, managing the sheer number of services, be they generated in-house or by a third party, that will be hosted on such an NGN is not a trivial task. The process of service orchestration (i.e. service blending) is complex and the major standards bodies have, as yet, been unable to define a suitable method. One of the contenders for the role of service orchestration is the Alcatel-Lucent Service Broker TM . BT has been engaged with Alcatel-Lucent during the past year on a proof of concept demonstration to test the Alcatel-Lucent Service Broker's suitability for this role. The findings have shown that this development can support and aid rapid service creation and blending while providing excellent levels of flexibility and programmability. IntroductionBT is already well on the way to converting its existing core network infrastructure to a next generation network (NGN) based on the Internet protocol (IP) and known as the 21st Century Network (21CN). NGNs such as 21CN offer communications operators a number of benefits, not least a reduction in operating costs [1], and a platform that allows new and innovative services to be developed and launched quickly and in a cost-effective way. In the past, new services have largely required independent platforms, each having common features such as billing and customer profile maintenance, often using different protocols. The result is a complex arrangement of networks and platforms involving a myriad of stove-pipe solutions. In contrast, NGNs such as 21CN, offer a common platform that can be used by all applications and services. Commonly used features can be aggregated into common capabilities (CC) [2], and currently there are 12 CCs in the 21CN architecture that can be reused across applications.The common platform allows new services to reuse previously developed functionality, reducing time to market and development costs. It is also possible to look beyond the 'walled garden' architecture that has been the norm and allow third parties to develop and provide services to customers.An important part of the BT NGN architecture is the IP multimedia subsystem (IMS) [3], defined originally as the core network for 3rd generation (3G) mobile systems by the 3rd Generation Partnership Project (3GPP). The IMS was first introduced in the Release 5 (R5) of the 3GPP set of standards. Later releases of the 3GPP standard included interfaces with wireless LAN systems (in R6) and fixed line systems (in R7), paving the way for fixed-mobile convergence (FMC) and providing for new levels of convergence and mobility. A typical scenario might, for example, allow a user to have a single profile for both fixed and mobile services, combining multiple devices. As such, the IMS will herald a new era...
