Abstract:

Next Generation Networks (NGN) is the evolution of the telecommunication core. The user has to execute multi-pass Authentication and Key Agreement (AKA) procedures in order to get access to the IP Multimedia Subsystem (IMS). This causes overhead on the AAA server and increases the delay of authenticating the user and that is because of unnecessary and repeated procedures and protocols. This paper presents an enhanced one-pass AKA procedure that eliminates the repeated steps without affecting the security level, in addition it reduces the Denial of Service (DoS) attacks. The presented mechanism has minimal impact on the network infrastructure and functionality and does not require any changes to the existing authentication protocols.

Abstract:

Modern subscribers of infocommunication services require a wide class of different services and applications, implying a wide variety of protocols, technologies and transmission rates. Networks are overloaded in the prevailing situation in the market of infocommunication services: they are overflowing with numerous customer interfaces, network layers and are controlled by too many control systems. High operating costs are pushing operators to look for solutions that simplify the operation, while maintaining the possibility of creating new services and ensuring the stability of existing sources of income from the provision of communication services. The NGN concept is the concept of building next-generation communication networks (Next-generation network), providing an unlimited set of services with flexible settings for their management, personalization, creation of new services through the unification of network solutions. Multiservice network is a communication network that is built in accordance with the NGN concept and provides an unlimited set of infocommunication services (VoIP, Internet, VPN, IPTV, VoD, etc.). An NGN is a packet-switched network suitable for the provision of telecommunication services and for the use of multiple broadband transport technologies with QoS enabled, in which the service-related functions are independent of the applied transport technologies. The main feature of NGN networks is the differentiation between services and transport technologies. This allows to view the network as a logically divided entity. Each layer of the network can evolve independently without affecting other layers. Inter-layer communication is based on open interfaces. The logical separation principle allows the provision of both existing and innovative services access technologies regardless of the used transport. The basic principle of the NGN concept is to separate from each other transfer and switch functions, call control functions and service control functions.

Abstract:

This paper provides the state of art and hints on how to lay the foundations of an adaptive QoS approach in Next Generation Networks (NGN). The key idea is to provide a model, which would offer one application version or another, depending on the Quality of Service (QoS) negotiated at the session establishment in a NGN. The stake of this research is a better-balanced usage of the network, for maximizing the service offered to the user given his or her network capacities. It encompasses the model for such an implementation in a NGN as IP Multimedia Subsystem (IMS).

Abstract:

The rapid evolution of the telecommunication domain increases the performance of different access networks continuously. New services, especially in the domain multimedia content distribution, require higher and higher bandwidth at the user’s and service provider’s side. Multimedia services like Video on Demand, IPTV, and live streaming were introduced in the past and are still improved in quality and quantity. Multimedia streams and Peer to Peer (P2P) file sharing dominates the worldwide Internet traffic nowadays and will continue further (Schulze, 2009). The user acceptance of enjoying multimedia content over the Internet will grow steadily together with the increasing quality of the available multimedia content. Network operators and service providers have to face the growths by increasing their service platform with higher performance and bandwidth or introducing a scalable solution. In this paper, the authors present an algorithm for scalable P2P live streaming in Next-Generation-Networks (NGN) that addresses this challenge. An evaluation proves the performance of the implementation of this algorithm in a demo scenario.

Abstract:

The telecommunication numbering system in Indonesia currently complies to the International TelecommunicationUnion (ITU) standard, that is ITU-T E.164. In accordance to both technology development and the growing of network users, ITU has also been designing future infrastructure network concept, namely Next Generation Network Infrastructure (NGNI). In its technical paper, ITU discusses future generation’s specification as well as current network migration scenarios towards Next Gereration Network (NGN) in developing countries and its impact on regulations, business processes, and the numbering system. The scenario described in the concept is yet universal and the implementation would be highly depending on the conditions of ones country. This paper proposes the roadmap of numbering system from the current state into NGN numbering for the case of Indonesia. The method used in this paper are benchmarking with several countries that have started with the transformation process, forecasting with regression method based on the existing trends and descriptive analysis. This paper has proposed the stages of numbering roadmap towards NGN numbering system, the achievement parameters, and the indicators that are suitable for Indonesia.

Abstract:

The subject of the study is multiservice communication network using the concept NGN (Next Generation Network) based on the open network architecture IMS (Internet Protocol Multimedia Subsystem), supporting a wide range services. The basis of this architecture is the IMS core, consisting of a set of specialized modules responsible for various functions for customer service. The purpose of the article is to analyze the existing technical capabilities of the IMS multimedia messaging subsystem and perspective solutions for the functioning of the NGN/IMS network efficiency in providing multimedia service. As the efficiency of the system, the capacity NGN/IMS networks is selected using the signaling system and protocols NGN. The capacity NGN/IMS networks during the establishment of a multimedia session was analyzed and the functional architecture of the IMS multimedia messaging subsystem that determine the interaction NGN signaling systems an protocols was explored. Manage the presentation Triple Play services to subscribers and simultaneously modify the media stream within the session allows the protocol for the initialization of the SIP and Diameter sessions, which are the main IMS signaling protocol. One of the important requirements for the IMS subsystem is the maintenance QoS (Quality of Service). A mathematical model for estimating the quality of communication services using a system GI/G/1/N based on the theory diffusion approximation is proposed. The research presented in this paper is very important for the theory queuing systems, since the article proposes a method for investigating multiservice communication networks with non-Poisson incoming flow and effective results are obtained for NGN/IMS networks. On the basis of the model analytical expressions are obtained, which allow evaluating the performance indicators of the Triple Play service. The proposed mathematical model can be used to solve a wide range of practical problems, including the management multiservice traffic in the process its transmission in multiservice telecommunications networks, taking into account the quality of service classes. Thus, studies NGN/IMS network capacity indicators using SIP protocols are relevant.

Abstract:

With the development of networks and wideband technology, Next Generation Network (NGN) evolves into integrated transmission network of the multimedia information which including data, voice, image, the real-time tasks, etc. The traditional IP network provides only "best-effort" service and cannot meet the needs of multi-media applications and the different demands of a variety of users for network transmission quality. On the basis of a detailed analysis to Differentiated service (DiffServ) model and the characteristics of MPEG-4 encoding, the QoS control strategy of video streaming in NGN is proposed. That is a QoS control strategy which uses priority of Inter-Frame combining with DiffServ model in network congestion. Simulation and testing results show that the strategy can improve the transmission quality of the video stream effectively in the case of limited bandwidth.

Abstract:

Next Generation Network (NGN) faces the challenge of the rapidly increasing amount of signaling. The growing amount of signaling is a consequence of several reasons arising from the fact that signaling is the main source of network intelligence, analysis, and user behavior monitoring. With the increase in signaling load and complexity, the network management becomes a challenging issue that can impact overall Quality of Service (QoS). To confront this issue, there is a need for reliable and forehand signaling transmission in NGN. As there is much confusion about the interpretation of this concept, this paper aims to provide an overview of the evolution of signaling transmission. Migration towards NGN is analyzed from the signaling perspective. The NGN signaling protocols and related transmission requirements are identified. Through the discussion of standard approaches, the paper considers our previously published approach to signaling transmission along with the current issues and emerging opportunities.

Abstract:

The next generation wireless network needs to provide seamless roaming among various access technologies in a heterogeneous environment. In allowing users to access any system at anytime and anywhere, the performance of mobility-enabled protocols is important. While Mobile IPv6 is generally used to support macro-mobility, integrating Mobile IPv6 with Session Initiation Protocol (SIP) to support IP traffic will lead to improved mobility performance. Advanced resource management techniques will ensure Quality of Service (QoS) during real-time mobility within the Next Generation Network (NGN) platform. The techniques may use a QoS Manager to allow end-to-end coordination and adaptation of Quality of Service. The function of the QoS Manager also includes dynamic allocation of resources during handover. Heterogeneous networks raise many challenges in security. A security entity can be configured within the QoS Manager to allow authentication and to maintain trust relationships in order to minimize threats during system handover. The next generation network needs to meet the above requirements of mobility, QoS, and security.

The performance indicators corporate multi-service networks based on the architectural concept of the following Next Generation Network (NGN) and Future Networks (FN) using a number of innovative technologies are considered. A significant difference between such networks and previous generation networks is that the architecture of future networks is based on technologies software defined networks, virtualization network functions and the multimedia communications subsystem. As a criterion for complex performance indicators corporate multiservice networks, we selected throughput, the coefficient effective use hardware and software systems, various resources, and probability-time characteristics. As a result of the study, a method for calculating the complex throughput indicators corporate multiservice networks based on the architectural concept NGN and FN using SDN (Software Defined Networking), NFV (Network Functions Virtualization) and IMS (Internet Protocol Multimedia Subsystem) technologies is proposed. Th essence of the new method is to find relationships with which you can calculate the maximum throughput of the communication network and the areas feasible solutions of the basic equation that belong to it. System and technical analysis showed that the transmitted heterogeneous traffic has a special structure – self-similarity properties (scale invariance) and a quantitative assessment of the degree traffic self-similarity using the Hurst parameter. Based on the proposed calculation method, the complex indicators of corporate multiservice networks are examined taking into account the parameters traffic self-similarity, QoS (Quality of Service) and QoE (Quality of Experience). Resource management methods in network nodes were studied to improve the throughput characteristics taking into account the numerous QoS & QoE parameters and the coefficient effective use hardware and software systems was determined. Based on the calculation method, analytical expressions have been obtained to evaluate the complex indicators corporate multiservice networks in establishing connections and in providing multimedia services with the necessary parameters. A numerical analysis is carried out and a graphical dependence of the maximum network throughput on the total number software and hardware systems is constructed for a given system load factor.

Abstract:

E-Health services comprise a broad range of healthcare services delivered by using information and communication technology. In order to support existing as well as emerging e-Health services over converged next generation network (NGN) architectures, there is a need for network QoS control mechanisms that meet the often stringent requirements of such services. In this paper, we evaluate the QoS support for e-Health services in the context of the Evolved Packet System (EPS), specified by the Third Generation Partnership Project (3GPP) as a multi-access all-IP NGN. We classify heterogeneous e-Health services based on context and network QoS requirements and propose a mapping to existing 3GPP QoS Class Identifiers (QCIs) that serve as a basis for the class-based QoS concept of the EPS. The proposed mapping aims to provide network operators with guidelines for meeting heterogeneous e-Health service requirements. As an example, we present the QoS requirements for a prototype e-Health service supporting tele-consultation between a patient and a doctor and illustrate the use of the proposed mapping to QCIs in standardized QoS control procedures.

Abstract:

Abstract Growing expectations for a fast access to information create strong demands for a universal telecommunication network architecture, which provides various services with strictly determined quality. Currently it is assumed that these requirements will be satisfied by Next Generation Network (NGN), which consists of two stratums and includes IP Multimedia Subsystem (IMS) elements. To guarantee Quality of Service (QoS) all NGN stratums have to be correctly designed and dimensioned. For this reason appropriate traffic models must be developed and applied, which should be efficient and simple enough for practical applications. In the paper such a traffic model of a single domain of NGN with transport stratum based on Multiprotocol Label Switching (MPLS) technology is presented. The model allows evaluation of mean transport stratum response time and can be useful for calculating time of processing requests in the entire NGN architecture. Results obtained using the presented model are described and discussed. As a result of the discussion, elementary relationships between network parameters and transport stratum response time are indicated.

Abstract:

The continuous evolution of Next Generation Internet (NGI) amplifies the demand for efficient and secure communication capable of responding effectively to the challenges posed by the emerging applications. For secure communication between two sensor nodes, a secret key is needed. Cryptographic key management is a challenging task in sensor networks as the hostile environment of sensor networks makes it more prone to attacks. Apart from resource constraints of the devices, unknown topology of the network, the higher risk of node capture and lack of a fixed infrastructure makes the key management more challenging in Wireless Sensor Network (WSN). Paper surveys different key Management schemes for WSN. The paper presents the efficiency versus security requirements tradeoffs in key management for WSN. Paper also proposes a novel key management protocol which provides strong resistance against replay attacks. The results obtained from the mathematical model based on conditional probability of the scheme suggest that the proposed key management in NGI is efficient and attack resistant.

Abstract:

With an ever increasing penetration of Internet Protocol (IP) technologies, the wireless industry is evolving the mobile core network towards all-IP network. The IP Multimedia Subsystem (IMS) is a standardised Next Generation Network (NGN) architectural framework defined by the 3rd Generation Partnership Project (3GPP) to bridge the gap between circuit-switched and packet-switched networks and consolidate both sides into on single all-IP network for all services. In this paper, we provide an insight into the limitation of the presence service, one of the fundamental building blocks of the IMS. Our prototype-based study is unique of its kind and helps identifying the factors which limit the scalability of the current version of the presence service (3GPP TS 23.141 version 7.2.0 Release 7 [1]), which will in turn dramatically limit the performance of advanced IMS services. We argue that the client-server paradigm behind the current IMS architecture does not suite the requirements of the IMS system, which defies the very purpose of its introduction. We finally elaborate on possible avenues for addressing this problem.

Abstract:

Develop a proposal for a management model that allows, through knowledge management, to preserve the quality of services during the technological evolution of networks in a telecommunications company. Today, BaghTel is considered the main telecommunications company in Iraq and some time ago it was acquired by the Iraqi government, which has generated a significant organizational transformation, added to the fact of the rapid technological evolution and the strong competition of the sector. These factors give rise to concern on the part of certain units regarding which management model can best adapt to these changes. In addition to these reasons, there is a need for companies like BaghTel to improve the management of this type of updates or migrations, which would later translate into improvements in the quality of services provided by the company. This study seeks to propose a management model that allows optimizing the administration of networks and services, during the organizational transformation processes that occur in a telecommunications company as a result of today's technological evolution. The importance of this work lies in the opportunity to optimize, through a management model, the way to control an important technological change, which will ensure and improve the service levels that any telecommunications company provides to its end users. The final process, measures and assessments, include a viewing and use of management indicators of the results obtained in BaghTel's Specialist Networks Management; this consists essentially of a periodic monitoring and evaluation of the key variables in the management of the TDM (Time Division Multiplexing) and NGN (next generation of networks) networks;

Abstract:

La provisión de Calidad de Servicio (QoS, Quality of Service) es uno de los aspectos más importantes en el desarrollo de la Red de Nueva Generación (NGN, Next Generation Network). En este sentido, el suministro de QoS en redes basadas en IP, requiere de un proceso de negociación en el que se deben identificar los protocolos e interfaces necesarias para establecer de forma clara los procedimientos a ejecutar entre los elementos y funciones involucrados. Este artículo describe el proceso de negociación de calidad del servicio en el contexto de la NGN, donde el usuario, la capa de transporte y la capa de servicio acuerdan los parámetros de QoS de la sesión que se va a establecer para lograr un servicio con calidad.

Abstract:

Kommunikationsnetzbetreiber suchen aufgrund der kontinuierlichen Preiserosion nach neuen Umsatzquellen. Neben den Perspektiven mobiler Datendienste setzen sie auf die Möglichkeiten neuer Kommunikationsnetze unter dem Schlagwort Next Generation Networks (NGN), um unter anderem die Servicequalität (Dienstgütequalität) definieren zu können. Hierzu müsste allerdings die bestehende Netzneutralität, die eine diskriminierungsfreie Übermittlung von Daten sicherstellt, abgeschafft werden. Diese Ambitionen stellen für Google eine signifikante Bedrohung seines Geschäftsmodells und seines unternehmerischen Erfolgs dar. Google hat in den letzten Jahren mit verschiedenen Investitionen, Beteiligungen und Akquisitionen auf der Ebene der Infrastruktur, der Endgeräte und der Anwendungen auf diese Bedrohung reagiert. Dabei handelt es sich nicht nur um eine reine Konterstrategie, sondern Google versucht damit, sein erfolgreiches Geschäftsmodell auf die Telekommunikation und hier insbesondere auf die Mobilfunknetze auszudehnen. Im Erfolgsfall könnte dies signifikante Veränderungen im Geschäftsmodell der Telekommunikationsunternehmen zur Folge haben.

Abstract:

The article considers the solving an urgent scientific problem, which is to improve the flow control means in the coordinated implementation of multi-way routing strategies and preventive limitation of traffic intensity entering the transport network, based on improving the flow control method in the stationary component of the Air Force communication system in order to increase its productivity. The paper analyzes the problem and shows that an important place in modern and promising telecommunications networks, which are developing in the direction of creating next-generation NGN networks, is given to flow control means both within the transport network and at the stage of access to it. The solution to this problem is to improve the mathematical models of flow control, which are the basis of modern technological solutions. The article proposes a method of flow control which provides a coherent solution to the problems of multi-way routing and preventive limitation of traffic intensity on the basis of both relative and absolute priorities. To ensure more adequate service a model of traffic control based on relative priorities is proposed. The practical implementation of the work results envisages a set of organizational-technical measures related to the principles of organizational, technological and algorithmic nature, which will increase the productivity of the stationary component of the Air Force communication system of the Armed Forces of Ukraine.

Abstract:

Development Trends of Air Passenger Transport Services and Service Distribution Channels Alongside their core service, i.e., passenger transportation, air carriers are nowadays providing numerous extra services, which are not directly related to transport. On the one hand, airlines are enlarging the scope of paid services provided on board an aircraft by, among other ways, splitting the air ticket fee and singling out the costs of such services as catering on board, checked-in luggage, airport check-in, etc. On the other hand, airline companies tend to provide mass services to their sales partners - ground transportation, car rental, insurance, hotel booking, etc. Provision of both the core and the extra services is closely connected with computerized reservation systems and the corresponding agent and customer access networks. These systems and networks form the basis of IT channels of service distribution. The present paper analyses the indicators and development trends of air transport services in combination with the development of service distribution channels and the information technologies lying at the basis of such channels. The paper also describes the structure and IT support of distribution channels. The authors have paid attention to the potential qualitative changes in the structure and possibilities of distribution of air passenger transportation services in view of the Next Generation Network (NGN) concept whose implementation has been started in the world.

Abstract:

З появою мультисервісних мереж з’явилися інтелектуальні сервіси (INS) і, відповідно, новий тип трафіку. Протягом довгого часу вважалося, що мережний трафік відповідає пуасонівським процесам, але подальші дослідження довели, що в трафіку деяких мереж наявний ефект самоподібності. Через властивості самоподібного трафіку традиційні методи розрахунку характеристик функціонування мереж дають занадто оптимістичні результати і призводять до недооцінки реального навантаження. Виникає актуальне питання визначення наявності ефекту самоподібності трафіку, що містить заявки на INS, а також урахування цього ефекту при формуванні аналітичної моделі інтелектуальної надбудови NGN (Next Generation Network). Саме цим питанням присвячена дана робота. На основі аналізу існуючих методів розрахунку показника Херста, що надає можливість визначити характер трафіку, обрано R/S метод, оскільки його використання дозволяє аналізувати велику кількість даних, а також не містить занадто великого обсягу обчислень. Даний метод реалізований за допомогою програми AutoSignal. Виходячи з аналізу отриманих результатів можна стверджувати, що трафік, що містить заявки на INS – це самоподібний процес. Ефект самоподібності проявляється в широкому діапазоні часу – від декількох годин до року. Проведені дослідження характеру трафіку визначили можливість вирішення актуальної задачі – розробки аналітичної моделі інтелектуальної надбудови NGN, яка відповідає за управління наданням INS, з урахуванням самоподібності трафіку. Для побудови аналітичної моделі інтелектуальної надбудови було використано апарат теорії масового обслуговування. Запропонована аналітична модель інтелектуальної надбудови, яка ураховує самоподібність потоку заявок на INS, надає можливість визначити потрібні мережні ресурси для забезпечення необхідного значення ефективності управління наданням INS.

Abstract:

Perkembangan teknologi telekomunikasi yang semakin pesat, membuat para operator dan vendor telekomunikasi harus dapat menyediakan layanan telekomunikasi yang aman, cepat, dan multi guna, untuk mendorong terciptanya ekosistem layanan telekomunikasi yang beragam bagi para penggunanya. Next Generation Network (NGN) merupakan sebuah teknologi masa depan yang mendukung beberapa layanan terintegrasi seperti voice, data, dan multimedia. Hal utama dari konsep NGN adalah konvergensi dan layanan yang berbasis IP sehingga diperlukan sebuah teknologi yang dikenal dengan IP Multimedia Subsystem (IMS). Agar pengiriman data dalam layanan IMS menjadi lebih efektif dan efisien maka diperlukan sebuah teori antrian yang tepat untuk digunakan sebagai pengatur aliran paket data. Penelitian ini melakukan pengamatan terhadap beberapa layanan pada jaringan IMS dengan menggunakan tiga teori antrian yang berbeda yaitu First In First Out (FIFO), Priority Queuing (PQ), dan Weighted-Fair Queuing (WFQ). Pengamatan dilakukan terhadap layanan Video Conference dan VoIP. Dari hasil simulasi dapat diketahui bahwa teori antrian WFQ pada layanan video conference menghasilkan rata-rata delay sebesar 9.22 ms , delay variation sebesar 0.036 ms dan packet loss sebesar 0.88%. Sedangkan untuk layanan VoIP menghasilkan rata-rata delay sebesar 144 ms, delay variation sebesar 0.021 ms, dan packet loss sebesar 0.05% serta menghasilkan rata-rata throughput sebesar 7.052 Mbps, sehingga teori antrian yang tepat digunakan dalam jaringan IMS dalam penelitian ini adalah WFQ.

In recent years, Internet of Things (IoT) and Cloud Computing are the hottest issues of Future Internet. However, there is a lack of common fabric for integrating IoT and Cloud. In telecommunications, the IMS (IP Multimedia Subsystem), based on the All-IP and Open Services Architecture, has been regarded as the trend for Next Generation Network (NGN). The IMS communication platform is the most suitable fabric for integrating IoT and Cloud. This paper focuses on different aspects including Cloud Service Framework, Data Sensing and Communication Technology, Collaborative Authentication and Privacy Protection Mechanism, Operation, Administration, and Maintenance (OA&M), Mobility and Energy-Saving Management, and Application Services. This paper not only provides the discussion of open challenges, but also proposes a possible solution based on the above-mentioned aspects for Future Internet.

A set of fixed-phone cluster management system was designed based on C&C08 program control unit and next generation network (NGN). C&C08 is responsible for the bottom access and transfer of the fixed-phone calls. Applying the computer telephony integration (CTI) technology we can realize the telephone call management through a computer. Using this system, fixed telephone managers can conduct limitation control for cluster management users information and implement list query of cost easily, so that managers can know the detail cost. In addition, based on the present situation of the telecom business, we designed four telecommunication services for enterprises and institutions, and added them to the fixed-phone cluster management system. For the cluster management users, they can subscribe to those services according to their needs.

Abstract:

By virtue of the rapid development of the Information and Communication Technology (ICT), people have owned various devices connected to the Internet to enjoy various emerging application services, such as multimedia related services. IP Multimedia Subsystem (IMS) is the integration platform for multimedia application services and provides a rich feature set of converged services in the Next Generation Network (NGN). IMS services are accessed by a user anytime and anywhere through his/her personal self IMS device, e.g., mobile device, equipped with a Universal Subscriber Identity Module (USIM) card. People have owned various devices connected to the Internet at homes or offices. However, some devices can not access IMS services without USIM cards embedded, which is called non-IMS devices. People wish that more devices without USIM cards embedded should be connected to the Internet on which IMS services are accessed in addition to the mobile devices equipped with USIM cards. Accordingly, we propose an Open Service Gateway Initiative (OSGi)-based IMS service gateway, in which OSGi technology is the dynamic module system for JAVA. The proposed gateway is authorized by a personal self IMS device such that IMS services are accessed by non-IMS devices, in this paper. Moreover, these non-IMS devices rely on different networks to access technologies and network protocols and the IMS service gateway proposed here adopts the OSGi framework for no problem of integration.

Abstract:

Long Term Evolution (LTE) is a leading 4G wireless broadband technology developed by the Third Generation Partnership Project (3GPP) Release 8. LTE is expected to provide very fast, highly responsive and cost effective data services and appears itself to be the right technology at the right time. LTE is becoming an ultimate choice for 4G services around the world due to its higher data rates and lower latency objectives. E-Health services comprise a wide range of healthcare services delivered by utilizing information and communication technology. In order to help existing and emerging e-Health services over converged next generation network (NGN) architectures, there is a need for network QoS control mechanisms that meet the often stringent requirements of such services. The mobile Health (m-health) is currently uniting major academic research worldwide to achieve innovative arrangements in the areas of healthcare. However, there are several challenges and issues that need to be addressed. In this paper we have proposed m-health care system based on 4G LTE network communication instead of existing 3G communication system. We will be monitoring QoS parameters like Delay, Throughput, Jitter, Energy Efficiency and Packet Data Rate for comparing 3G and 4G LTE usage over health care applications. We will further experiment the parameters with graph based analysis.

Abstract:

Telecom infrastructures are facing unprecedented challenges, with increasing demands on network capacity. Today, network operators must determine how to expand the existing access network infrastructure into networks capable of satisfying the user’s requirements. Thus, in this context, providers need to identify the technological solutions that enable them to profitably serve customers and support future needs. However, the identification of the “best” solution is a difficult task. Although the cost of bandwidth in the active layer has reduced significantly (and continually) in recent years, the cost of the civil works—such as digging and trenching—represents a major barrier for operators to deploy NGA infrastructure. Duct is a critical part of the next-generation access networks, and its sharing would reduce or eliminate this capital cost and this barrier to entry. The aim of this paper is to provide a better understanding of the economics of broadband access networks technologies (wireline and wireless), their role in the deployment of several services in different regions, and the development of competition in the access networks.

Abstract:

The IP Multimedia Subsystem (IMS), specified by the 3rd Generation Partnership Project (3GPP), is a key element in the next-generation network (NGN) converged architecture.Extending the IMS towards provisioning support for locationbased services (LBS) will enable enhanced services and offer new revenues to the operator. Conveying location information in the IMS and connecting the IMS with a positioning system are still open issues. This paper presents the design and implementation of an IMS Location Server (ILS) integrating IMS with a positioning system. From the IMS perspective, the ILS serves as a service enabler for LBS. In order to demonstrate proof-of-concept in enhancing IMS-based services, two prototype service scenarios have been implemented: Location-aware Messaging (LaM), andLocation-aware Push-to-Talk over cellular (LaPoC). Some work has been done by the IETF in the area of location information transport based on the Session Initiation Protocol (SIP). This paper proposes improvements in this area, primarily related to reducing the necessary amount of signaling with the specification of a new type of location filter. We have conducted measurements in a laboratory environment in order to illustrate our proposed solution and verify the benefits compared to existing solutions in terms of traffic load and session establishment time. Furthermore, we present a case study integrating the ILS with the Ericsson Mobile Positioning System (MPS).

Abstract:

The next generation communication network (NGCN) is expected to provide higher spectral efficiency, low latency, large throughput and massive machine-to-machine type communications. In this regard, the design of the multi-carrier waveform (MCW) is posing a major research problem for the NGCN. To overcome the stated problem, a lot of state-of-the-art work exists that proposes various MCW alternative to the standard orthogonal frequency division multiplexing (OFDM) waveform. It is true that OFDM was used in a number of real-time communication systems of fourth generation (4G) networks. However, their use in the upcoming fifth generation (5G) network is not very feasible. This is because of the strict requirements of 5G communication systems, which also extend beyond 5G systems; hence rendering the use of OFDM infeasible for newer communication standards. To satisfy the requirements of upcoming communication networks, there is a dire need for MCWs with better flexibility. In this regard, a precoding-based MCW has been proposed. The proposed MCW fulfills the requirements of the NGCN in terms of low peak-to-average power ratio (PAPR), high spectral efficiency and throughput. The MCW proposed in this work uses power-domain multiplexing such as non-orthogonal multiple access (NOMA) and phase rotation by using the selective mapping (SLM) and generalized chirp-like (GCL) precoding of the input signal to the universal filtered multi-carriers (UFMC) modulations. Statistical analysis of the PAPR is presented by using the complementary cumulative distribution function (CCDF). The MATLAB® simulations have been carried out to implement the CCDF of PAPR and results show that a PAPR gain of 5.4 dB is obtained when the proposed waveform is compared with the standard NOMA-UFMC waveform at clip rate of 10−3, using 4-QAM.

Abstract:

This paper addresses the problem of survival and growth of incumbent telecommunication operators. In particular, this paper investigates the extent to which the platform-based approach is appropriate for the internationalisation strategy (platform leadership) of incumbent telecommunications operators in the context of the transition to the Next Generation Network (NGN). It examines the case of BT in the UK, as a large-scale first mover in this transition, exploring the major transformation project BT 21st Century Network (BT21CN). The case demonstrates how the platform-based approach can be used to promote business transformation of an incumbent telecom operator in a turbulent environment. The platform architecture integrates two main features that are usually treated in different contexts and time frames in the literature: (i) the reusability of components and sub-systems (typically in the automotive industry); and (ii) the openness of the platform to external actors in order to drive innovation in the industry (typically in the ICT industry). BT21CN emerged as an industry platform, made possible by the maturation of the Internet Protocol (IP) as a "common technology" able to transport not only data, but also real time voice and video, with an acceptable quality of service (QoS). Reusability can help reducing costs and decreasing time-to-market for new products and services. However, openness of the platform to external actors has still limited impact due to the limited success of BT (and incumbent telecom operators in general) in their process of internationalisation. Thus, in the context of BT (and of potentially other incumbent telecom operators), the limitations in their process of internationalisation have a negative impact on the evolutionary dynamics of the platform-based approach.
