Address translation problems in IMS based next generation networks

The development of packed based multimedia networks reached a turning point when the ITU-T and the ETSI have incorporated the IMS to the NGN. With the fast development of mobile communication more and more services and content are available. In contrast with fix network telephony both the services and the devices are personalized in the “mobile world”. Services, known from the Internet - like e-mail, chat, browsing, presence, etc. – are already available via mobile devices as well. The IMS originally wanted to exploit both the benefits of mobile networks and the fancy services of the Internet. But today it is already more than that. IMS is the core of the next generation telecommunication networks and a basis for fix-mobile convergent services. The fact however that IMS was originally a “mobile” standard, where IPv6 was not oddity generated some problems for the fix networks, where IPv4 is used. In this article I give an overview of these problems and mention some solutions as well

Next generation networks for distributed electronic resources: Opportunities and challenges

The changes in the lifestyle of the people, new applications, technological developments and the telecommunication market drive the adoption Next Generation Network (NGN) as the new network architecture. NGN has a service-centric architecture which promotes agile creation of services and then maintenance of these services with end-to-end QoS support. In the current era, every internet user is a potential electronic resource user. Due to the transition from the traditional mode of collections to the electronic resources and the heterogeneity and distributed nature of the electronic resources, a state of the art communication infrastructure is the key component of electronic resource providers. In this regard, NGNs can offer numerous advantages to the electronic resource providers. In this paper the use of NGNs for delivering distributed electronic resources is investigated. The opportunities and challenges are presented

A user-centric approach to service creation and delivery over next generation networks

Next Generation Networks (NGN) provide Telecommunications operators with the possibility to share their resources and infrastructure, facilitate the interoperability with other networks, and simplify and unify the management, operation and maintenance of service offerings, thus enabling the fast and cost-effective creation of new personal, broadband ubiquitous services. Unfortunately, service creation over NGN is far from the success of service creation in the Web, especially when it comes to Web 2.0. This paper presents a novel approach to service creation and delivery, with a platform that opens to non-technically skilled users the possibility to create, manage and share their own convergent (NGN-based and Web-based) services. To this end, the business approach to user-generated services is analyzed and the technological bases supporting the proposal are explained

SMS over LTE : interoperability between legacy and next generation networks

To increase the trust and acceptance of Next Generation Networks (NGN) by new and existing subscribers, it is necessary to ensure that the most popular services of legacy networks (GSM/GPRS) are still in place. The Short Message Service (SMS) is a widespread data service with high revenue for telecommunication operators, which allows the exchange of short messages between fixed, mobile and, indirectly, Internet subscribers. In this context, it is essential to extend this service for the NGN and allow its interaction with the new messaging services. With that in mind, a study was carried out to ensure the coexistence between SMS and the Instant Messaging (IM) service present in NGN. The present study identifies the relevant technical specifications impacting on the functionality of the IP Multimedia Subsystem (IMS) messaging services so that the interoperability with SMS can be ensured. The results of this study, covered in this article, aim to help the comprehension of the proposed interoperability solution, and demonstrate that the exchange of messages between legacy and NGN messaging services or equipment can be successfully accomplished. In this context, both SMS and IMS messaging services are detailed, along with the main protocols they involve. Finally, the entity responsible for ensuring message interoperability - the IP Short Message Gateway (IP-SM-GW) - is presented and tested in a commercial delivery content testbed.(undefined
