    It is vital for financial services companies to ensure the rapid implementation of new processes to meet speed-to-market, service quality and compliance requirements. This has to be done against a background of increased complexity. An integrated approach to business processes allows products, processes, systems, data and the applications that underpin them to evolve quickly. Whether it’s providing a loan, setting up an insurance policy, or executing an investment instruction, optimizing the sale-to-fulfillment process will always win new business, cement customer loyalty, and reduce costs. Lack of integration across lending, payments and trading, on the other hand, simply presents competitors who are more efficient with a huge profit opportunity.Web Service, business process, integration, financial services, integration, modeling

    Get PDF
    In the modern market, e-commerce is absolutely essential in business marketing and advertising. Many studies have been conducted to explore the relations between players and companies by creating the trust within security and culture. Various models have been proposed to show the reliability of trust that in a successful e-commerce website. In this paper, we have built a new framework to aggregate the e-commerce culture with the facilities of the websites that can attract more players to increase the trust between the players and companies. This paper also explores factors in e-commerce related to Jordanian culture and religions, in the context of the great increase in the use of smart phones by all sectors of society around the country. Our new framework will explore the vision for companies to enhance services with increasing the trust by considering many different keys such as scalability, delivery on time and protected accounts with more website facilities

    Because of advances in technology service provision, the regulator has adopted a technology neutral licensing regime. However, it is challenged with issues of interconnection and uncompetitive practices, largely driven by the incumbents. Increased competition resulting from the entry of service providers in a generally ‘small’ market has given users a stronger bargaining position. Various initiatives of government and the private sector in growing the optical-fiber backbone will go a long way in enhancing various services, particularly for regions remote from the capital. There is great need for public-private partnering to realise performance objectives

    Quality of Service Provisioning for Heterogeneous Services in Cognitive Radio-enabled Internet of Things

    IEEE The Internet of Things (IoT) is a network of interconnected objects, in which every object in the world seeks to communicate and exchange information actively. This exponential growth of interconnected objects increases the demand for wireless spectrum. However, providing wireless channel access to every communicating object while ensuring its guaranteed quality of service (QoS) requirements is challenging and has not yet been explored, especially for IoT-enabled mission-critical applications and services. Meanwhile, Cognitive Radio-enabled Internet of Things (CR-IoT) is an emerging field that is considered the future of IoT. The combination of CR technology and IoT can better handle the increasing demands of various applications such as manufacturing, logistics, retail, environment, public safety, healthcare, food, and drugs. However, due to the limited and dynamic resource availability, CR-IoT cannot accommodate all types of users. In this paper, we first examine the availability of a licensed channel on the basis of its primary users' activities (e.g., traffic patterns). Second, we propose a priority-based secondary user (SU) call admission and channel allocation scheme, which is further based on a priority-based dynamic channel reservation scheme. The objective of our study is to reduce the blocking probability of higher-priority SU calls while maintaining a sufficient level of channel utilization. The arrival rates of SU calls of all priority classes are estimated using a Markov chain model, and further channels for each priority class are reserved based on this analysis. We compare the performance of the proposed scheme with the greedy non-priority and fair proportion schemes in terms of the SU call-blocking probability, SU call-dropping probability, channel utilization, and throughput. Numerical results show that the proposed priority scheme outperforms the greedy non-priority and fair proportion schemes

    Space-Based Information Infrastructure Architecture for Broadband Services

    This study addressed four tasks: (1) identify satellite-addressable information infrastructure markets; (2) perform network analysis for space-based information infrastructure; (3) develop conceptual architectures; and (4) economic assessment of architectures. The report concludes that satellites will have a major role in the national and global information infrastructure, requiring seamless integration between terrestrial and satellite networks. The proposed LEO, MEO, and GEO satellite systems have satellite characteristics that vary widely. They include delay, delay variations, poorer link quality and beam/satellite handover. The barriers against seamless interoperability between satellite and terrestrial networks are discussed. These barriers are the lack of compatible parameters, standards and protocols, which are presently being evaluated and reduced

    Improved planning and resource management in next generation green mobile communication networks

    In upcoming years, mobile communication networks will experience a disruptive reinventing process through the deployment of post 5th Generation (5G) mobile networks. Profound impacts are expected on network planning processes, maintenance and operations, on mobile services, subscribers with major changes in their data consumption and generation behaviours, as well as on devices itself, with a myriad of different equipment communicating over such networks. Post 5G will be characterized by a profound transformation of several aspects: processes, technology, economic, social, but also environmental aspects, with energy efficiency and carbon neutrality playing an important role. It will represent a network of networks: where different types of access networks will coexist, an increasing diversity of devices of different nature, massive cloud computing utilization and subscribers with unprecedented data-consuming behaviours. All at greater throughput and quality of service, as unseen in previous generations. The present research work uses 5G new radio (NR) latest release as baseline for developing the research activities, with future networks post 5G NR in focus. Two approaches were followed: i) method re-engineering, to propose new mechanisms and overcome existing or predictably existing limitations and ii) concept design and innovation, to propose and present innovative methods or mechanisms to enhance and improve the design, planning, operation, maintenance and optimization of 5G networks. Four main research areas were addressed, focusing on optimization and enhancement of 5G NR future networks, the usage of edge virtualized functions, subscriber’s behavior towards the generation of data and a carbon sequestering model aiming to achieve carbon neutrality. Several contributions have been made and demonstrated, either through models of methodologies that will, on each of the research areas, provide significant improvements and enhancements from the planning phase to the operational phase, always focusing on optimizing resource management. All the contributions are retro compatible with 5G NR and can also be applied to what starts being foreseen as future mobile networks. From the subscriber’s perspective and the ultimate goal of providing the best quality of experience possible, still considering the mobile network operator’s (MNO) perspective, the different proposed or developed approaches resulted in optimization methods for the numerous problems identified throughout the work. Overall, all of such contributed individually but aggregately as a whole to improve and enhance globally future mobile networks. Therefore, an answer to the main question was provided: how to further optimize a next-generation network - developed with optimization in mind - making it even more efficient while, simultaneously, becoming neutral concerning carbon emissions. The developed model for MNOs which aimed to achieve carbon neutrality through CO2 sequestration together with the subscriber’s behaviour model - topics still not deeply focused nowadays – are two of the main contributions of this thesis and of utmost importance for post-5G networks.Nos próximos anos espera-se que as redes de comunicações móveis se reinventem para lá da 5ª Geração (5G), com impactos profundos ao nível da forma como são planeadas, mantidas e operacionalizadas, ao nível do comportamento dos subscritores de serviços móveis, e através de uma miríade de dispositivos a comunicar através das mesmas. Estas redes serão profundamente transformadoras em termos tecnológicos, económicos, sociais, mas também ambientais, sendo a eficiência energética e a neutralidade carbónica aspetos que sofrem uma profunda melhoria. Paradoxalmente, numa rede em que coexistirão diferentes tipos de redes de acesso, mais dispositivos, utilização massiva de sistema de computação em nuvem, e subscritores com comportamentos de consumo de serviços inéditos nas gerações anteriores. O trabalho desenvolvido utiliza como base a release mais recente das redes 5G NR (New Radio), sendo o principal focus as redes pós-5G. Foi adotada uma abordagem de "reengenharia de métodos” (com o objetivo de propor mecanismos para resolver limitações existentes ou previsíveis) e de “inovação e design de conceitos”, em que são apresentadas técnicas e metodologias inovadoras, com o principal objetivo de contribuir para um desenho e operação otimizadas desta geração de redes celulares. Quatro grandes áreas de investigação foram endereçadas, contribuindo individualmente para um todo: melhorias e otimização generalizada de redes pós-5G, a utilização de virtualização de funções de rede, a análise comportamental dos subscritores no respeitante à geração e consumo de tráfego e finalmente, um modelo de sequestro de carbono com o objetivo de compensar as emissões produzidas por esse tipo de redes que se prevê ser massiva, almejando atingir a neutralidade carbónica. Como resultado deste trabalho, foram feitas e demonstradas várias contribuições, através de modelos ou metodologias, representando em cada área de investigação melhorias e otimizações, que, todas contribuindo para o mesmo objetivo, tiveram em consideração a retro compatibilidade e aplicabilidade ao que se prevê que sejam as futuras redes pós 5G. Focando sempre na perspetiva do subscritor da melhor experiência possível, mas também no lado do operador de serviço móvel – que pretende otimizar as suas redes, reduzir custos e maximizar o nível de qualidade de serviço prestado - as diferentes abordagens que foram desenvolvidas ou propostas, tiveram como resultado a resolução ou otimização dos diferentes problemas identificados, contribuindo de forma agregada para a melhoria do sistema no seu todo, respondendo à questão principal de como otimizar ainda mais uma rede desenvolvida para ser extremamente eficiente, tornando-a, simultaneamente, neutra em termos de emissões de carbono. Das principais contribuições deste trabalho relevam-se precisamente o modelo de compensação das emissões de CO2, com vista à neutralidade carbónica e um modelo de análise comportamental dos subscritores, dois temas ainda pouco explorados e extremamente importantes em contexto de redes futuras pós-5G

    By fostering the finalization of open standards and the convergence of voice, video and data, the internet protocol provides an ideal driver for the definition of the infrastructure of new multimedia and advanced communications applications (Adams & Bhalla, 2005). The key advantages of Voice over Internet Protocol (VoiP) for enterprises have been the promise of lower costs, infrastructure consolidation and increased flexibility. Carriers are also positioning VoiP as a cost-saving business solution. It is an application which seemed like a godsend to business and people alike who rely on telephony services (Blood, 2005). The aim of this study was to investigate what factors may influence the adoption of VoiP as a technology as a West Australia context. Specifically the research undertook a case study using an establish call centre in a government agency, City of Melville. The company is a provider of wide range of services including recreation centres, aquatic centres, libraries, creches, pre-school centres, community centres, food inspection services, citizenships, recycling, planning and building services, maintenance, streetscapes, landscaping disability services, immunisation clinics, cultural and educational centres, environmental preservation and management. This study analysed the steps through to adoption of VoiP and IP telephony from the original technology for the Melville City Council call centre. Also, the procedures towards acquisition and installation of the supporting framework that eases the implementation and day to day running are depicted. The main impacts on the company as a result of the implementation in terms of cost reduction and implications, staff satisfaction and benefits, ease of business operations has been reported in this study. Statistics of the business functions and operations based on VoiP solutions were critically analyzed. Results from the research suggested further research needs to be undertaken on factor affecting the adoption of VoiP in a Western Australia context
