    The modern telecom industry’s operation is based on the use of global standards. Standardization is the culminating phase of the technology value chain. The industry enjoys a plurality of Standards Development Organizations (SDO’s) that range in their scope, mission, and organizational structure. The creation of telecom standards, particularly in core technologies, is fueled by the intellectual power of the global R&D community. A special role in this is played by SDO’s associated with professional societies, such as the IEEE. IEEE and ITU are correspondingly at the root and apogee of the global standardization process. The IEEE Communications Society (ComSoc) has over the 50 years of its existence mainly supported scholarly precompetitive research. Now, however, ComSoc is moving towards serving practitioners and industry by also fostering standardization. ITU, on the other hand, has become increasingly aware of the value of academic scholarship in the standardization process. Bringing the intellectual power of the world R&D community into global standardization efforts ensures the best possible quality standards for next generation networks. ITU-T’s Kaleidoscope conference, technically cosponsored by IEEE ComSoc, serves as an important component of this approach. View full abstract»

    This paper discusses requirements and several research activities of new generation networks (NWGN) coming after next generation network (NGN) currently driven by ITU-T. The detailed research profiles of Japanese governmental projects such as AKAR1 project are introduced with possible future applications. Photonic technology has been applied for high speed communications, possible high speed communication services are also investigated in this paper. This paper addresses that photonic technology is also important for energy reduction of these services, which is one of the keenest issues in the world for the next decade. Among other concerns to increase power consumption of communication services, network appliances and sensors are not negligible because of their number and the penetration rate in ubiquitous or pervasive network services. This paper also introduces the maximum power consumption of these sensor devices required for keeping sustainable services. View full abstract»

    Digital communications is both pervasive and vital across society. This creates a growing public interest in the technical standards that proscribe public communications. The public is demanding, "open standards. " The rallying cry, "open standards," means different things to different groups. This paper reviews the different needs of specific groups of society and develops ten different requirements of Open standards. To implement these requirements, actions by standardization organizations, international bodies (e.g., WIPO, WTO) and national patent office rules are proposed. Interestingly, technical changes, in the form of new standards, rather than legal or policy changes, appear to be the most important mechanism to meet the requirements of open standards.

    Next Generation Networks (NGN) are meant to "enable a richer set of applications to the end-user", creating a network platform that allows for the rapid creation of new services without the need to add new infrastructure. Significant progress has been made in the standardization of NGN architecture and protocol implementation in several different standards bodies. There has, however, been a lack of progress in the development of standardized open APIs for the developer community to create innovative applications for the NGN platform. This paper outlines the importance of such APIs, what has been achieved so far in the standards bodies and a brief overview of emerging de-facto standards such as Google's OpenSocial and Android APIs. The paper concludes with a brief set of issues that standards bodies need to resolve in relation to open APIs. View full abstract»

  • Structuring the next generation network using a standards-based service delivery platform

    Page(s): 33 - 40

    The Next Generation Network (NGN) represents a telecommunications network that provides a variety of services to customers across converged telco, enterprise and Internet infrastructures. The NGN promotes separation of service implementations from network infrastructure by using service enablers. Service enablers are reusable abstractions that provide access to network capabilities. Enablers are used by applications to create services for customers and offer external enterprises access to NGN capabilities. No appropriate NGN service platform architecture is standardised to date. This paper shows how services and service enablers are defined and structured within a standards-based NGN service platform architecture. We motivate the Service Delivery Platform (SDP) framework for standardising the NGN service platform architecture. The SDP framework defines an extendable, technology-neutral service platform architecture. The framework consists of building blocks structured according to Generic Service Oriented Architectures (GSOAs) presented here. The GSOAs are implementable using standards-based technologies. After providing background on the NGN. we elaborate on the SDP and GSOA. We present our SDP framework using multiple GSOAs. In addition, we discuss and evaluate a SDP implementation.

    Page(s): 41 - 46
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (641 KB) |  | HTML iconHTML  

    This paper shows an innovative proposal of integration between circuit switched (CS) domain and IP multimedia subsystem (IMS) in the ambit of voice call continuity (VCC) service. VCC is a fundamental piece of IMS architecture proposed by 3GPP (3rd generation partnership project) specifications. This service offers continuity of a call when a mobile user moves from a domain to another, e.g. from circuit switching access network to IP access network. Mobility is a fundamental characteristic of convergent and heterogeneous networks, like IMS architecture, which is an implementation of next generation networks (NGN). 3GPP specifications do not mention anything about the protocol and the methods used to integrate the functional entities of VCC service that are distributed through CS domain and IMS. Then, this paper propose could be used for standardization of this integration, suggesting a method and a protocol for it. View full abstract»

    Next generation networks will accommodate heterogeneous networks with high level of distribution and complexity. Thus, it will issue new challenges to the operations support system (OSS) architectures. The traditional OSS architectures will no longer be able support the complexity of the NGNs as a result; the redesign of the management architecture is necessary. The Service-Oriented Architecture is the solution to successfully manage the complexity of the NGNs. This paper presents existing management architectures and the concept of the SOA as well as the technologies that enables the SOA. The technologies that enable SOA are presented. Finally, a SOA-based management framework following the logic of the next generation operation support systems (NGOSS) developed in the TM-forum is proposed. View full abstract»

  • Future challenges of irsimple protocol: Efficient flow control scheme and long distance capability

    Page(s): 57 - 62

    IrSimple protocol, recently proposed by the infrared data association (IrDA), promises a simple Infrared protocol for fast, wireless communication between mobile devices and digital home appliances. The existing flow control scheme adopted by IrSimple protocol consumes a considerable amount of energy and resources by retransmitting large sized Information frame in case the receiving secondary station remains busy due to handling other tasks and therefore can not send the acknowledgement of received frames. In our previous work, we proposed an efficient flow control scheme which effectively reduces the redundant data retransmissions by using receiver ready (RR) supervisory frames and assumed all the frames are received error free during flow control procedure. In this paper, we examine in detail all possible cases where Information frames or Supervisory frames may be lost at different stages of flow control to investigate the effectiveness of our proposed flow control scheme. Furthermore, we investigate the long distance capability of current IrDA links which is another future challenge to enhance IrSimple protocol applications. View full abstract»

    Resource and admission control function (RACF) is the main part of resource management architecture in next generation networks (NGN). In this paper we analyze the effect of different resource control schemes in RACF architecture on some network performance parameters and show that a dynamic policy for scheme selection will outperform the static one. The dynamic policy results in better resource utilization for Best Effort traffic while providing the required resource for QoS-guaranteed traffic. Likewise, we present some suggestions about service control functions (SCF) and RACF responsibilities so that NGN layers independence will be maintained more than before. This led us to a bit alteration in DIAMETER protocol used between RACF and SCF. View full abstract»

    We have proposed a distributed storage system based on self-encryption scheme for the purpose of protecting private information stored in mobile handsets. We define self- encryption scheme as an encryption scheme whose encryption key is generated from the information contained in the target file itself. In our proposed system, the information is split into two pieces and one of them is stored in a local storage of a mobile handset and the other is uploaded to a network storage, and they are encrypted respectively. In this paper, we construct a user-based private storage system with the authentication and the secure path that IMS provides. To relax the load of mobile handsets, not the mobile handset but the network server encrypts an uploaded plaintext file into s distributed data using self-encryption scheme. Sharing a storage infrastructure based on P2P overlay network with other users, the intruder cannot get all the distributed data only by hacking a single server. Moreover, if the data for uploading is already stored by other user, physical upload procedure is omitted, thus reducing the uploading time. IMS providing index application server, a supernode P2P net work storage provides efficient look-up with fault-resilience and high scalability. View full abstract»

  • Positional gesture for advanced smart terminals: Simple gesture text input for syllabic scripts like Myanmar, Khmer and Bangla

    Page(s): 77 - 84

    In the next generation network (NGN), various kinds of advanced smart mobile terminals will be used for various communication services. We believe that text typing on small mobile devices will become more popular than it is today and also necessary for developing countries such as Myanmar (Burma), Cambodia and Bangladesh etc. In these countries, however, there is no proper or easy text input method for mobile devices yet. Positional gesture text input is a novel concept of text input for syllabic scripts like Myanmar, Khmer and Bangla languages. Text input of syllabic scripts poses a unique challenge because many syllabic characters are formed by combinations of consonants, dependent vowel signs, tones and subscript consonants etc. And thus, text input for syllabic scripts is still difficult even with PC keyboards. In this paper, we propose very simple gesture recognition for syllabic scripts text input based on their writing natures. It is accessible even for first time users and applicable for many mobile computing devices such as tablet PCs, mobile phones, PDAs and portable game players etc. View full abstract»

    Productivity is one of the top reasons, why Enterprises implement remote access methods to access their corporate networks. While there are several remote access methods defined today for accessing corporate networks, however there are several enhancements to consider to make next generation remote access implementation to run smoothly in existing corporate networks. In this paper, we review and identify shortcomings of existing remote access methods. We propose 2 solutions based on Mobile IP to overcome shortcomings of the existing methods and address the coexistence of our proposed techniques with existing ones. Compared with an existing VPN access method with PPP, our proposed solution offer the following advantages in terms of better usability as well as a stronger prevention of information leakage, by unifying the two authentications (one for the Layer 2 access to the carrier and the other for Layer 3 access to the enterprise network) into one at the enterprise network.

    In recent years, IMS/MMD architectures have been gaining importance as the key technologies for the Next Generation Network, which is standardized by ITU-T. These architectures utilize SIP for session management and, in particular, MMD utilizes Mobile IP for mobility support of mobile nodes. When both protocols are used at the same time, the problem of inefficiency and delay in the MMD session controls for handover arises due to the fact that they work independently. In this paper, we propose fast session control methods that involve cooperation between these protocols. Further, we implement and evaluate our proposed methods, and show the improvements in session control time. View full abstract»

    The high-speed communication service in future mass transportation systems is a challenging target for the design of next generation protocols. Especially bullet trains are promising, but the details of the real environments are little known to us. In this paper, we address the estimation of quality of service (QoS) in real mobile environments, assuming a radio link is proprietor and using only commercially available network devices. Firstly, we make a definition of invariant communication qualities in bullet trains, which are not dependent on each measurement. Then we propose a two buffer model-based QoS estimation method for the link qualities of commercial 3G wireless IP networks, even though the radio link is a black box to users and the protocol is proprietary. Finally, using this estimation method, we measured the raw packet transmission characteristics of CDMA2000 1timesEV-DO in bullet trains. View full abstract»

    Virtual worlds and social networks in general are emerging phenomena which can benefit from information in the real world. For example, since its introduction in 2003, Second Life has grown explosively, and today is inhabited by nearly 10 million residents from around the globe. A fair number of the residents make part of or their entire real world living by running business on Second Life. Communications in this vast digital continent happen between avatars and make use of web facilities. Leveraging context aware capabilities such as presence, location, identity, anchored in the real world opens monetizing opportunities for the service providers. Services on the real word were mashed with Second Life used here as a typical example of a 3D virtual world. The authors present in this paper how the integration of these two worlds was achieved. This integration leveraged rapid application prototyping, development and deployment and brings the potential of a dramatic reduction in service lifecycle costs. View full abstract»

    The complex Web of standards setting bodies (SSBs) has triggered the need for co-operation and co-ordination in ICT standards setting at various levels. This paper looks at the co-ordination between SSBs. It provides an account of how today's diversity on ICT standards setting emerged, and how it should be evaluated. The state-of-the-art in co-ordination between different (types of) standards bodies is discussed, and some improvements to the current situation are proposed. SSBs need to be flexible enough to constantly adapt to their stakeholders needs. Division of labour and improved transposition processes might help improve the current situation. Moreover, European policy makers might need to re-evaluate their stance towards standards consortia. View full abstract»

    The inherent need for stable standards is difficult to reconcile with the ITU aim to develop state-of-the-art standards, and combine standardization with innovation. Standards' change is then inevitable; the consequence is that it increases transaction costs and calls prior interoperability into question. In this paper we analyze the problem of standards change as a feature of innovation. We want to understand the role that standards' dynamics plays in processes associated with committee when the specifications and technologies co-evolve. To perform this study, we consider disruptions in the technology and/or the value chain simultaneously to classify innovations into four types. By identifying the type of innovation at hand, the innovation-specific issues of standards change that are likely to occur can be singled out. Tools can be devised to assist the various stakeholders in making their decisions. We illustrate this with the case of standards for the next generation Ethernet networks. View full abstract»

    This paper proposes strategic innovations through NGN standardisation to enable the establishment of a consumer-centric business model (CBM) for wireless services. This leads to the evolution of a wireless environment, called here a ubiquitous consumer wireless world (UCWW). In view of the novelty of the concept, the paper focuses on developing the context and argument for the CBM, and the underpinning technological innovations - key new infrastructural entities and functionalities - required for its realisation. The technological innovations proposed may be evolutionary, but considering the potential social, economic and policy impact on wireless communications equipment, service providers and users, the effect may be described as revolutionary.
