The next generation networks is based on packet switching which involves voice, data and multimedia such as audio and video. It provides fixed mobile convergence to all valued customers. The 8 core exchanges in India is now commissioned and about 136 core switches have started to work. The BSNL has planned a huge network wherein all the traditional voice and data customers migrate from C-Dot TDM towards...
The objective of this paper is to define a mathematic model for the dimensioning of LTE Rel-8 network. After describing the mechanisms influencing the dimensioning such us the Scheduling, QOS and LTE capacity, we define the strategy of the planning and the objective function which aim to minimize the number of the base stations and the capacities of the wired links to deploy. The mathematical formulation...
The convergence of backbone networks is widely discussed under the name of next generation networks (NGNs). But the local loops such as the air interface of mobile networks and the last mile of fixed networks are still owned by single operators. Therefore they show an oligopolistic market structure which may prevent market-driven allocation and lead to high end-user prices. In this paper incentives...
With the development of network technology, people's demand on real-time and multimedia feature of the network services has become more and more sophisticated, that requiring Quality of Service of Next Generation Networks with high features. Firstly, this thesis systematically analyzes the characteristics and limitations of IntServ and DiffServ which supports the mechanisms of QoS. Secondly, describes...
With the fast development of all kinds of communication technologies and the popularization of Internet, Next Generation Networks have a major impact on existing communications technology, which cover conventional PSTN (Public Switched Telephone Network) type of data and voice communications to multiple applications, consisting of voice, data and video and other new media applications. The key issue...
This article describes the results of the draft implementation of the Internet Protocol Version Six (IPv6) in “Instituto Tecnológico de Soledad Atlántico-ITSA” campus network. To adequately implement the IPv6 protocol a study of existing devices and network services of the institute was performed, tests were designed in accordance to the production environment and put up to make the necessary adjustments...
The CAMEL and the IMS are representative service platforms in the circuit switched (CS) and packet switched (PS) domain. The integration of the CAMEL and the IMS will bring tremendous benefits to the network operators and end users. Many researchers invest in investigating the mechanism of invoking the CAMEL service from the PS domain, however, there are few studies about the mechanism of invoking...
In this paper main particularities of the infrastructure of NGN are considered, instances base technologies, which meet the requirements and which can be used in transport network NGN are described.
Next-Generation Networks (NGNs) employ the Internet Protocol (IP) over a wide variety of packet-switching technologies, which often lack in really effective fault resilience enabling features. An overlay MPLS infrastructure with its fast-reroute mechanisms can be deployed to overcome such an issue. Addressing NGNs robust to single link and node failures, an off-line method to effectively calculate...
In this paper, we present our research aiming at building a petabit router model for next generation networks. Considering the increasing traffic requirements on the Internet, current gigabit and terabit speed routers will soon not be able to meet user demand. One of the promising trends of router evolution is to build next generation routers with enhanced memory capacity and computing resources,...
In order to solve the problems that the process of the evolution is only in one step and the investment in network is so costly when the network in nowadays evolutes to NGN(Next Generation Networking), this paper has get a deep research about the soft switch, media gateway control protocol, access gateway and media server and such kind of technology and then submit a kind of design methodology, through...
Forthcoming next generation networks (NGNs) introduce a new trend of integration into one all-IP platform. This process will decouple VoIP services from the network providers, introducing new service distribution aspects. VoIP devices will be enabled to seamlessly switch between wideband and narrowband speech operators and roam across diverse networks on demand, even during active calls. To design...

IPv6 is the key technology of the next generation Internet, this paper analyses the strategies for managing the transition from IPv4 to IPv6, designs the campus network transition scheme based on IPv6 automatic tunnel technology, and verifies the feasibility that IPv4 network can access IPv6 network through IPv6 automatic tunnel technology by the experiment.
The Next-Generation Network (NGN) has Application Network Interfaces (ANIs) by which 3rd party application services are easily created. For session-control ANI (for example, ldquomakeCallSessionldquo of the Parlay-X), Application Server (AS) functions process a call using three SIP methods (REFER method, 3rd Party Call Control (3PCC) method, Media Bridge method). We propose a SIP method escalation...
Guarantee of QoS (quality of service) and mobility management are important research areas in NGN (next generation networks). Most people have been taking a route of mobile IP over MPLS (MIoM) to meet such challenge. However, MIoM has a drawback considering that MPLS itself does not have any direct control over transmission at the physical layer, instead, it has to rely on existing data link layer...
Driven by liberalization, competition, technological advances and evolving market demand, many telecom carriers consider implementing distributed network architecture, with a common, packet-based transport layer for voice and data. NGN holds the promise of offering a range of new data and multimedia services, giving the carrier access to new revenues. In migration scenarios different aspects are considered...
The last decades has seen tremendous shifts in the telecommunications landscape. Telecom operators and service providers, are responding by adopting strategies that lower their costs of operations and allow them to offer rapidly new services with better revenues. The next generation network (NGN) is a network architecture that is ultimately designed for new service provision, independent of access...
