Nowadays, mobile users can switch between different available networks, for example, nearby WiFi networks or their standard mobile operator network. Soon it will be extended to other operators. However, unless telecommunication operators can directly benefit from allowing a user to switch to another operator, operators have an incentive to keep their network quality of service confidential to a...

The fixed-charge capacitated multicommodity network design formulation (CMND) represents a generic model for a wide range of applications in planning the construction, development, improvement, and operation of transportation, logistics, telecommunication, and production systems (Balakrishnan, Magnanti, and Mirchandani 1997 and references therein). In these applications, multiple commodities (g...

Two Large-Scale Network Design Problems In this work we consider two large-scale network design problems arising in network routing and provisioning. The first problem combines long-term business and design decisions on large-scale telecommunication networks. The problem integrates different elements of network business planning such as capacity expansion, routing and protection and equipment m...

The broadcasting & telecommunication services in the future will be converged and be serviced on mobile devices. However, the current ICT infrastructure does not fully meet the future demand for those converged, realistic, intelligent, and personalized services. The Korean government is going to establish a high speed next generation network called UBcN (Ultra-Broadband Convergence Network) by ...

In this paper we consider the local access telecommunication network expansion problem, in which growing demand can be satis®ed by expanding cable capacities and/or installing concentrators in the network. The problem is known to be NP-hard. We prove that the problem is weakly NP-hard, and present a pseudo-polynomial dynamic programming algorithm for the problem, with time complexity O…nB2† and...

Solutions in the network and service management layers of telecommunications management architectures are currently fragmented both in terms of standards and products. It is often, therefore, difficult for the developers of management systems to reuse and integrate management software from different sources in cost-effective solutions spanning the various TMN layers. This paper presents the ana...

Every nation wants to achieve Universal Access of telecommunication services due to its importance to the economy and national life. Unfortunately in sub-Saharan Africa, telecommunication services are either scarce or non-existent in rural areas. However, previous telecommunication policies have enabled the provision of various network technologies in Africa. What type of policy is needed to pu...

This paper introduces telecommunication services engineering through a definition of services, of network architectures that run services, and of methods, techniques and tools used to develop services. We emphasize the Intelligent Network (IN), the Telecommunication Management Network (TMN) and TINA architectures; we also discuss the impact of the Internet on these architectures.

This work deals with a multi-period capacitated location problem inspired by telecommunication access network planning problems, where demands and costs vary from one period to another. On each concentrator site, several capacitated concentrators can be installed at each period. Similarly, several capacitated modules can be installed at each period between each terminal and concentrator sites. ...
