Advanced service creation using distributed object technology

The Eureka-ITEA2 WellCom project addresses issues related to the creation, delivery and management of advanced multimedia applications and services in the context of distributed home environment. To enable the delivery of such services with the required quality and security, WellCom proposes to push a part of the service logic as close as possible to the end-user. The paper presents some results of the WellCom project enabling to create synergies between the TV screen displaying multimedia content and mobile terminals. A unique experience with new types of group interactions (i.e. advanced local and community services) will be proposed.

In the next 12 months (1999-2000), several leading European motor manufacturers are likely to launch fully integrated line fit and aftermarket fit telematics units, allowing location specific telematics services to be delivered to their customers. Trials and demonstrations of telematics services, delivered via a number of ad hoc or proprietary protocols, have been a feature of RAC development projects and pilot customer trials since 1995. This experience has allowed, not only an opportunity to gather customer feedback from representative services, it has also allowed a sound business understanding to be developed against which service delivery platforms can be scoped to match likely customer services and volumes. RAC are developing telematics services and systems to be GSM network and service provider independent on the assumption that the growth of the telematics services market will be restricted if it is tied to specific market players and segmentation. The potential for GSM SIM Application Toolkit to offer customised services whilst retaining the benefits of working within the GSM standards framework is particularly attractive to a telematics service provider such as the RAC. Wireless Application Protocol (WAP), for micro-browser based services and alternative GSM bearers, such as the GPRS are particularly relevant to telematics service delivery and are likely to feature prominently in the next generation of telematics hardware.

The home network system (HNS, for short) provides value-added and context-aware services for home users, by orchestrating networked home appliances and sensors. Although the HNS services have been developed by system vendors, there exist strong needs that the end-users create their own services according to their convenience. This paper presents a novel service creation environment, called Sensor Service Binder (SSB), which provides a user-friendly interface for creating context-aware services within the HNS. Built on top of the service-oriented HNS, the SSB allows non-expert users to register contexts using the sensors, and to bind the registered context to any operation of the networked appliances. Experimental evaluation with an actual HNS showed that the effort for service creation was reduced to 10% by introducing the proposed SSB.Keywordshome network systemhome appliancessensorscontext-aware servicesend-user development

The existing Service Creation Environments (SCEs) speed up the design of IN service logic, but the whole process of service creation is still relatively long. Very limited support for the service specification and validation provided by the SCEs is one of the reasons. This paper presents a graphical simulation environment called INAP Wrapper that supports IN service prototyping and validation at the early stages of service creation. INAP Wrapper is built around the standard SDL specification of the INAP CS1/2 protocol developed by ETSI. The ETSI specification has been extended by the SDL models of switched network, service management, and service control function. Service validation is based on the SDL simulation capabilities of Telelogic Tau tool suite and the animation capabilities of the INAP Wrapper GUI. The paper presents the INAP Wrapper environment and its industrial applications.KeywordsService LogicBlock TypeService CreationService ValidationService PrototypeThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Todaypsilas user wants exciting new services at reduced costs. Legacy ldquovoicerdquo services are considered to be bare minimum. To satisfy their customers and be competitive, Telecom service providers are pressured to provide converged and differentiated services at reduced cost. IP multimedia subsystem (IMS) is touted to be next generation telecom architecture that enables service providers to achieve this requirement. IMS architecture allows service providers to offer a variety of multimedia services in the service layer. Service providers today are building an eco-system with partner vendors to offer new services in this layer. With the success of person-to-person and person-to-content services in the Internet world, it becomes more compelling for mobile device manufactures and service providers to reach out to developer community to create more innovative applications with IMS infrastructure. This paper describes how ldquoservice creationrdquo focus is being shifted from operators and mobile device vendors to third party developers. It explores the benefits of having a service creation platform to aid in developing such services. It outlines the elements of software development kit (SDK) which will help in maximizing productivity and enables developers to focus on creativity. This paper analyzes the need for a complete simulated setup for developers to create and test their services before deploying into real network. There are different service creation environments that are available like service delivery platforms (SDP), JAIN SLEE, and OSA/Parlay etc. In this paper the primary discussion is on the usage of standards based API in IMS/SIP SDK. It dwells more into JSR API for client development and application server development. It also touches upon how SIP SDK can be interfaced with Web 2.0 components.

NTT's advanced IN provides telecommunication services, management services, and service customization services. It also provides operations for advanced IN services. Each is executed by corresponding application software on a separate platform. We propose an integrated service creation environment (SCE) in which service logic programs for network control (SLP(N)s), service logic programs for customization (SLP(C)s), management logic programs (MLPs) and operation logic programs (OLPs) are specified and generated. Design concepts of the SCE are computer-aided graphical specification description, knowledge-based automatic specification conversion, 3-step verification, a verification support method based on reverse engineering, and a method of configuring individual creation environments by using a common platform. The SCE is an integration of individual application software creation environments. As an example of a creation environment, an SLP creation environment is described in detail. The SCE makes it possible to greatly reduce the amount of description and verification time.

This paper describes the functionality of the research version of HP’s Service Creation Environment (SCE). Some of the design decisions and reasons behind them are given.

The advent of deregulation will have a radical effect on the traditional telecommunications market. Increased market competitiveness will mean that productivity and quality of service must be increased, while lead times and production costs must be decreased. Existing actors in the field will have to change their core business to remain viable. These changes will mean that a sophisticated Service Creation Environment is required to support service creation.

This paper describes the extended PARLAY X for the Adaptive Context-aware Personalized Service (ACPS) in a ubiquitous computing environment. It can be expected that the context-awareness, adaptation and personalization for the Quality of Service (QoS) / Quality of Experience (QoE) in a ubiquitous computing environment will be deployed. But the existing PARLAY X is lacking when considering QoS / QoE in network. To address this issue, this paper suggests the extended PARLAY X for ACPS. The objective of this paper is to support the architecture and the Application Programming Interface (API) of the network service for the context-awareness, adaptation and personalization in a ubiquitous computing environment. ACPS provides a user with QoS / QoE in network according to the detected context such as location, speed and user’s preference. The architecture of the extended PARLAY X for ACPS is comprised of a Service Creation Environment (SCE), the semantic context broker, and the overlay network. SCE uses Model Driven Architecture (MDA)-based Unified Modeling Language (UML) / Object Constraint Language (OCL) for an expression of context-awareness, adaptation, and personalization. The semantic context broker is a broker role between the SCE and PARLAY gateways. The overlay network is a broker role for QoS / QoE between PARLAY gateway and the IP network.

OSGi is considered as one of the fundamental technologies underpinning telematics services, and has attracted both academic and commercial interest. Because of a desire and mandates to deliver telematics services on OSGi environments, professionals have identified a key issue that need to be addressed: the service delivery would suffer from the situation of low bandwidth and unstable links. In this work, we benefit from the inherent characteristics of mobile agents and develop OSGi-Based mobile agents to address this challenge. Furthermore, the mobile agents are enhanced with a Java bytecode extractor which makes a mobile agent partially reside in a contactless smart card for service invocations, and with a risk-enabled reputation model which supports a mobile agent for information filtering to reduce the size of data that need to be carried.

BackgroundThe medical field is in the midst of a massive expansion in telemedical services. However, it is not possible to say to what extent telemedical offerings can be designed to meet needs in the German healthcare system. This study provides insights into demand-oriented care using telemedical services for gynecological patients.MethodsA total of 262 patients who received systemic therapy for gynecological oncology were surveyed anonymously using a questionnaire regarding their acceptance of telemedicine from February 2021 to April 2021.ResultsInsufficient computer skills were associated with less acceptance of telemedicine treatment by gynecological oncology patients and presented a barrier. However, the patient’s level of education was not related to the level of acceptance. Long travel distances from medical facilities and some types of patient occupations significantly increased the acceptance of telemedicine services. A high level of education, on the other hand, was not associated with the approval of telemedical approaches. Long journeys and work commitments increased the acceptance of telemedical visits.ConclusionsThe results of this study show that the factors investigated have an influence on the acceptance of telemedical offerings by patients. Barriers such as insufficient computer skills must be taken into account when implementing telemedicine services. Telemedicine can provide physical and economic relief for patients if telemedical planning is tailored to their needs.

This paper proposes an intelligent agent-based intelligent networks service creation environment on the IN architecture and concept models, which is called intelligent service creation environment (ISCE), and mainly discusses the architecture and the service creation environment on the basis of intelligent agent technology. We describe how to construct the planes of IN on the intelligent agent and introduce the intelligent service creation environment on it. Since the ISCE benefits from intelligent agent properties such as autonomy and intelligence, it possesses many new characteristics, such as adaptability, distribution, autonomy, and self-verification. Finally, this paper deals with problems which remain to be studied in this topic.

An integrated and systematic approach for the development of telematic services in heterogeneous distributed platforms

Building new advanced multimedia telecommunications services in a distributed and heterogeneous environment is very difficult, unless there is a methodology to support the entire service development process in a structured and systematic manner, and assist and constrain service designers and developers by setting out goals and providing specific means to achieve these goals. Therefore, in this paper, after a brief presentation of a proposed service creation methodology, its service design phase is examined in detail focusing on the essential activities and artifacts. In this process, the exploitation of important service engineering techniques and UML modelling principles is especially considered. Finally, alternative and complementary approaches for service design are highlighted and a validation attempt is briefly outlined.
