Communication Web Services and JAIN-SLEE Integration Challenges

Meshing up telecommunication and IT resources seems to be the real challenge for supporting the evolution towards the next generation of Web Services. In telecom world, JAIN-SLEE (JAIN Service Logic Execution Environment) is an emerging standard specification for Java service platforms targeted to host value added services, composed of telecom and IT services. In this paper we describe StarSLEE platform which extends JAIN-SLEE in order to compose JAIN-SLEE services with Web services and the StarSCE service creation environment which allows exporting value added services as communication web services, and we analyze open issues that must be addressed to introduce Web Services in new telecom service platforms

Communication Web Services Composition and Integration

Nowadays, the development of services that span over both the Internet and telephony networks is driving significant efforts towards the integration of services offered by IT providers with telecom operators ones. Web Services have often been recommended for providing, composing and realizing Telecom services but introducing them means facing up with several challenges. This work sharpens benefits and drawbacks of Web Service applications within a Telecom environment focusing in particular on JAIN SLEE architecture, which defines a standard environment targeted at communication-based applications

Soa-based guidelines for value-added service development on jain slee environments.

The appropriation of the new technologies is a key aspect to maintain high competitiveness in a globalized economy for telecom carriers. The benefits providedby these new technologies allow them to easily adapt to the market conditions and to satisfy the changing needs of increasingly demanding users. One of these technologiesis the JAIN SLEE specification, which presents a highly robust platformfor rapid development and deployment of new value-added services. However thehigh degree of complexity of this technology limits the exploitation of its benefitsand capabilities. In this paper, we propose a set of guidelines for value-added service development on JAIN SLEE environments based in the principles and guidelines for service creation defined in SOA, in order to facilitate this process

A conceptual model of an access-technology-agnostic delivery mechanism for ICT4D services

Information and Communication Technology for Development (ICT4D) is an emerging research area that is concerned with the beneficial applications of Information and Communications Technology (ICT) to achieve developmental goals. ICT4D is thus concerned with designing and developing innovative technologies for resource-constrained environments for applications in key areas of social development such as health, agriculture and education. The ICT4D initiatives, therefore, are driving three main tasks, namely developing the required infrastructure (connectivity, electricity and computing devices) sustainably, building the required ICT human capacity, and providing access to digital content and services. Each of these three main thrusts necessitates innovation. This study addresses the evident lack of delivery mechanisms to facilitate access to digital content and services to end-users through the technologies that these end-users already possess. This lack of innovative delivery mechanisms is both an impediment to achieving equitable access to digital content and service and an opportunity to innovate. Therefore, drawing from the theoretical background of ICT4D, this study develops a set of technical and socio-technical requirements that the missing delivery mechanisms should satisfy. The study also explores the Service Delivery Platform (SDP) concept as a technically viable basis for the required delivery mechanisms. The study then develops a conceptual model of an Access-Technology-Agnostic Delivery Mechanism as a possible delivery mechanism that facilitates equitable access to digital content and services within an ICT4D context. The relevance of the conceptual model is established and, through a prototype implementation, the technical feasibility and utility of the conceptual model is demonstrated. The conceptual model is demonstrated through a proof of concept implementation using standards-based open source technologies. The proof of concept clearly demonstrates that the access-technology-agnostic delivery of digital content and services is achievable, thus making the same service accessible through different access technologies. In developing the Access-Technology-Agnostic Delivery Mechanism, this study contributes through innovation to providing access to digital content and services in an access-technology-agnostic manner

Service composition based on SIP peer-to-peer networks

Today the telecommunication market is faced with the situation that customers are requesting for new telecommunication services, especially value added services. The concept of Next Generation Networks (NGN) seems to be a solution for this, so this concept finds its way into the telecommunication area. These customer expectations have emerged in the context of NGN and the associated migration of the telecommunication networks from traditional circuit-switched towards packet-switched networks. One fundamental aspect of the NGN concept is to outsource the intelligence of services from the switching plane onto separated Service Delivery Platforms using SIP (Session Initiation Protocol) to provide the required signalling functionality. Caused by this migration process towards NGN SIP has appeared as the major signalling protocol for IP (Internet Protocol) based NGN. This will lead in contrast to ISDN (Integrated Services Digital Network) and IN (Intelligent Network) to significantly lower dependences among the network and services and enables to implement new services much easier and faster. In addition, further concepts from the IT (Information Technology) namely SOA (Service-Oriented Architecture) have largely influenced the telecommunication sector forced by amalgamation of IT and telecommunications. The benefit of applying SOA in telecommunication services is the acceleration of service creation and delivery. Main features of the SOA are that services are reusable, discoverable combinable and independently accessible from any location. Integration of those features offers a broader flexibility and efficiency for varying demands on services. This thesis proposes a novel framework for service provisioning and composition in SIP-based peer-to-peer networks applying the principles of SOA. One key contribution of the framework is the approach to enable the provisioning and composition of services which is performed by applying SIP. Based on this, the framework provides a flexible and fast way to request the creation for composite services. Furthermore the framework enables to request and combine multimodal value-added services, which means that they are no longer limited regarding media types such as audio, video and text. The proposed framework has been validated by a prototype implementation

From mashups to telco mashups: A survey

Given their increasing popularity and novel requirements and characteristics, telco mashups deserve an analysis that goes beyond what's available for mashups in general. Here, the authors cluster telco services into different types, analyze their features, derive a telco mashup reference architecture, and survey how well existing mashup tools can respond to these mashups' novel needs. © 2012 IEEE
