Design & Deploy Web 2.0 enable services over Next Generation Network Platform

The Next Generation Networks (NGN) aims to integrate for IP-based telecom infrastructures and provide most advance & high speed emerging value added services. NGN capable to provide higher innovative services, these services will able to integrate communication and Web service into a single platform. IP Multimedia Subsystem, a NGN leading technology, enables a variety of NGN-compliant communications services to interoperate while being accessed through different kinds of access networks, preferably broadband. IMS-NGN services essential by both consumer and corporate users are by now used to access services, even communications services through the web and web-based communities and social networks, It is key for success of IMS-based services to be provided with efficient web access, so users can benefit from those new services by using web-based applications and user interfaces, not only NGN-IMS User Equipments and SIP protocol. Many Service are under planning which provided only under convergence of IMS & Web 2.0. Convergence between Web 2.0 and NGN-IMS creates and serves new invented innovative, entertainment and information appealing as well as user centric services and applications. These services merge features from WWW and Communication worlds. On the one hand, interactivity, ubiquity, social orientation, user participation and content generation, etc. are relevant characteristics coming from Web 2.0 services. Parallel IMS enables services including multimedia telephony, media sharing (video-audio), instant messaging with presence and context, online directory, etc. all of them applicable to mobile, fixed or convergent telecom networks. With this paper, this paper brings out the benefits of adopting web 2.0 technologies for telecom services. As the services are today mainly driven by the user's needs, and proposed the concept of unique customizable service interface

Platform for open innovation and integrated solutions: the case of BT and its Next Generation Network (NGN)

This paper analyzes how innovation in services is being organised in the telecommunication industry after the bubble burst in the beginning of the 2000’s and how BT is applying the concept of ‘open innovation’ in order to sustain its competitiveness. After the bubble burst in the beginning of the 2000’s, the telecommunications industry is trying to find its way to growth. Internet services and broadband have changed the way customers perceive communication services. Traditional telecommunication companies, like BT, Deutsche Telekom and France Telecom have been urging to change in order to survive and sustain its competitiveness. One outcome of the industry was that the traditional PSTN (Public Switched Telecommunications Network) technology was not suitable anymore to deliver the multimedia services demanded by customers. The IP (Internet Protocol) has become an unprecedented agreement in the telecommunications industry and the traditional telecommunications companies started to transform its infrastructure based on this Internet-based technology. While this infrastructure transformation is under way, another huge challenge is to change the way these traditional telecommunications companies create, integrate and deliver new services. Service innovation on top of the IP platform is the ultimate challenge. The research was conducted through interviews and analysis of documents such as reports, newspaper articles and official Internet websites. The reports included annual reports of suppliers and incumbent service providers, and documents of regulators. The interviews were conducted with senior managers, managers and other practitioners of incumbent telecommunications service providers and suppliers, regulators, consultants and market research analysts. Initial findings suggest that incumbent telecommunications firms will be increasingly extracting value from platform and software sharing, exposing its ‘capabilities’ to third parties and developing business models to interoperate with other companies, co-creating new services. Thus, the ability to expose their capabilities in services, not to hide them, will be determinant of its success. Also important is the ability to offer integrated solutions to large firms as part of the service portfolio. And, in this context, the concept of open innovation and value innovation also find a fertile ground to be applied in services in the communication industry. Important dynamic capabilities identified in this context are strategic planning, project management, new product/service development (especially software development), supported by systems integration

Future Trends and Challenges for Mobile and Convergent Networks

Some traffic characteristics like real-time, location-based, and community-inspired, as well as the exponential increase on the data traffic in mobile networks, are challenging the academia and standardization communities to manage these networks in completely novel and intelligent ways, otherwise, current network infrastructures can not offer a connection service with an acceptable quality for both emergent traffic demand and application requisites. In this way, a very relevant research problem that needs to be addressed is how a heterogeneous wireless access infrastructure should be controlled to offer a network access with a proper level of quality for diverse flows ending at multi-mode devices in mobile scenarios. The current chapter reviews recent research and standardization work developed under the most used wireless access technologies and mobile access proposals. It comprehensively outlines the impact on the deployment of those technologies in future networking environments, not only on the network performance but also in how the most important requirements of several relevant players, such as, content providers, network operators, and users/terminals can be addressed. Finally, the chapter concludes referring the most notable aspects in how the environment of future networks are expected to evolve like technology convergence, service convergence, terminal convergence, market convergence, environmental awareness, energy-efficiency, self-organized and intelligent infrastructure, as well as the most important functional requisites to be addressed through that infrastructure such as flow mobility, data offloading, load balancing and vertical multihoming.Comment: In book 4G & Beyond: The Convergence of Networks, Devices and Services, Nova Science Publishers, 201

Multi-protocol correlation : data record analyses and correlator design

This thesis has two main goals. The first one is to design a user configurable multiprotocol correlator and implement a prototype of said design. The second goal is to identify and propose a method to match different data records from different protocols. In essence, this thesis is about correlation of records which contain information about protocols or services that are generally used in telecommunication networks. In order to reach the two main goals of this thesis, we need to combine our knowledge from the programming world with our knowledge from the networking world. Correlation can be done on multiple levels; you can correlate protocol messages, and you can correlate whole calls or transactions which allows you to perform correlation across sections of a network. We approach this problem by gathering protocol signaling data, specifications on how the protocols work, and log files with examples. With this knowledge we were able to identify many of the problem areas related to correlation of the main protocols to be used in this thesis. We designed a configurable correlator that could be configured to overcome the problem areas related to correlation provided enough data was given. The prototype correlator was tested both on correctness and performance. Then, in order to validate the correctness and preciseness of our developed prototype correlator, we compare the correlation results obtained from our tool with the results obtained using Utel System ´s STINGA NGN Monitor. The comparison shows that the correlation results from our prototype correlator are satisfactor

Implementation and Performance Evaluation of an NGN prototype using WiMax as an Access Technology

Telecommunications networks have evolved to IP-based networks, commonly known as Next Generation Networks (NGN). The biggest challenge in providing high quality realtime multimedia applications is achieving a Quality of Service (QoS) consistent with user expectations. One of the key additional factors affecting QoS is the existence of different QoS mechanisms on the heterogeneous technologies used on NGN platforms. This research investigates the techniques used to achieve consistent QoS on network technologies that use different QoS techniques. Numerous proposals for solving the end-to-end QoS problem in IP networks have adopted policy-based management, use of signalling protocols for communicating applications QoS requirements across different Network Elements and QoS provisioning in Network Elements. Such solutions are dependent on the use of traffic classification and knowledge of the QoS requirements of applications and services on the networks. This research identifies the practical difficulties involved in meeting the QoS requirements of network traffic between WiMax and an IP core network. In the work, a solution based on the concept of class-of-service mapping is proposed. In the proposed solution, QoS is implemented on the two networks and the concept of class-of-service mapping is used to integrate the two QoS systems. This essentially provides consistent QoS to applications as they traverse the two network domains and hence meet end-user QoS expectations. The work is evaluated through a NGN prototype to determine the capabilities of the networks to deliver real-time media that meets user expectations
