Management of service sessions in an NGN-SOA execution environment [Next-Generation Telco IT Architectures]

Abstract: Collective intelligence is the key asset behind Web 2.0. Nowadays, users can share contents and information, but they are also able to compose services thanks to new user-oriented service platforms. In this article a distributed orchestration service execution environment for converged service platforms running over next-generation networks is presented, together with its main support function, the Dispatcher, an element which carries out load balancing and policy enforcement. Taking advantage of the intelligence and support operations offered by NGNs, this kind of SEE is specifically useful for telecommunication operators entering the value added service market, because it simplifies the implementation of their service-specific security and billing policies, and additionally allows easy service execution management for non-expert end users by offering service start and stop functionalities at the push of a button.

Multi-Level Context Management and Inference Framework for Smart Telecommunication Services.

Abstract: Telco operators and other players are searching for intelligent value-added services, i.e., communication applications that take advantage of the huge amount of user data available to the operators (location, contact lists, etc.) in order to adapt themselves to the preferences and context of each individual. However, the current networks of the operators lack the proper infrastructure to handle context data in a clean and unified way, so smart context-aware applications are extremely difficult to engineer, develop and deploy. Accordingly in this paper a global context processing architecture is presented. In addition, the monitoring of users in order to extract and process the context is a task potentially resource consuming. That is a significant problem in global telco deployments.This paper also presents a proposal for a multilevel context management framework for smart telecommunications services, whose objective is to optimise the available processing resources of the presented architecture to provide contextual monitoring to a high number of subscribers with limited resources.

Deployment of contextual corporate telco services based on protocol adaptation in the NGN environment

Abstract: Deployment of contextual services is usually constrained to specific areas where contextual behavior can be obtained, mainly due to coverage limitations of context acquisition devices. Although end customers highly appreciate contextual services, those limitations make such services difficult to commercialize. In this article we present a practical deployment of a contextual service offered by a convergent telecommunications operator, whose functionality is to provide intelligent context-based call routing and rerouting, orchestrated from the operator's service layer. It is based on IMS control layer capabilities to properly capture the situation of the end user in a ubiquitous coverage area. The user's context is stored in a network-centric element in order to leverage that information across different services, optimizing the system by increasing the quality of the information captured and processed. This implementation proves that value-added contextual services may be built efficiently today using available products and protocols. Since contextual services will likely be a valuable part of a service provider's portfolio, this implementation can help creators of new contextual services to meet cost and time-to-market objectives.

Guest editorial: new converged telecommunications applications for the end user

Abstract: The very first and most universal telecommunication application is voice, or, in other words, the telephone. Let us start this article by highlighting an important milestone in the industry. In mid-July 2010 (the time of this writing) it was announced (by the GSMA Association) that global mobile connections surpass 5 billion (18 months after the 4 billion connection milestone, with predictions for 6 billion in the first half of 2012), meaning 74 percent penetration. Is that not impressive? Think of other technologies like TV, or other sectors like banks, automotive? that do not have those universality rates. It is astonishing that in a few years (almost) every citizen of the world will use (mobile) telecommunications services. This success story is not only a privilege but certainly a responsibility for the advance of the world society. Innovation in telecommunications services for all these billions of users is certainly a rewarding challenge.
