“…Britvic (2004) specifies the strategic steps to plan and deploy the UMTS radio network, the core network, and the access transport network. Previous studies have provided many solutions to plan, dimen-sion, and deploy the UMTS radio networks (Harmatos et al, 1999;Wu et al, 2003Wu et al, , 2005Jamaa et al, 2004;Maple et al, 2004;Juttner et al, 2005;Neubauer et al, 2005). Different models and methods have been developed to find the optimal topology of the cells if the basic traffic models and location information to install base stations can be provided by mobile operators.…”

Current literature provides many practical tools and theoretical methods to design, plan, and dimension Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) radio networks but overlooks the algorithms of network planning and dimensioning for core networks of GSM, UMTS and IP Multimedia Subsystem (IMS). This paper introduces an algorithm for traffic, bandwidth and throughput dimensioning of the network entities in the UMTS core network, based on the traffic and throughput generated or absorbed in the interfaces of the network entities. A case study is provided to verify the algorithms created for UMTS core network. This paper helps UMTS network operators dimension and build an optimum network to deliver the best quality of service for users. The algorithms developed in the paper have been successfully applied in dimensioning a nationwide UMTS network in North Africa and adopted in an optimization tool by a mobile operator in the United States in 2008-2009.

“…Once we are satisfied with the coverage, the next step is to allocate different channels (frequencies) to the BSs in order to minimize interference in the network while being able to reuse the frequencies in other parts of the network. A first paper by Neubauer and Toeltsch [18] and a second by Ramzi [19] outline the main differences at the radio level between GSM and UMTS networks. They also explain the different steps in order to plan the radio portion (also called radio access network-RAN) of UMTS networks.…”

In this paper, we present a literature review on the topological planning problem of third generation (3G) cellular networks based on the universal mobile telecommunications system (UMTS) standard. After describing the UMTS architecture, we introduce each subproblem and present major works that have been done. The cell, the access and the core network planning problems have all been considered as well as a more global approach (when more than one subproblems are considered simultaneously). Both planning and expansion algorithms are also included in this review. The goal of this paper is to present and classify the different research works that have been done so that it can be used as a starting point for future research on topological design of UMTS networks.• The optimal number of BSs.• The best location to install the BSs. • The type (or model) of BSs.

“…With reference to the GPRS=EDGE section, monitoring on the Gb links (Ricciato, Vacirca, Karner, 2005)) can be measured for each cell, and these data used to pinpoint the need for capacity increase in those areas yielding recurrent signs of poor performance. Such novel approach is still in the exploratory phase, but early preliminary results are promising (Ricciato et al, 2006a) about the applicability of such data to complement the current practice of radio network optimization and capacity enhancement (Neubauer, Toeltsch, 2005).…”

A 3G network is a magnificently complex object embedded in a highly heterogeneous and ever-changing usage environment. It combines the functional complexity of the wireless cellular paradigm with the protocol dynamics of TCP=IP networks. Understanding such an environment is more urgent and at the same time more difficult than for legacy 2G networks. Continuous traffic monitoring by means of an advanced system, coupled with routine expert-driven traffic analysis, provides an in-depth understanding of the status and performances of the network as well as of the statistical behaviour of the user population. Such knowledge allows for a better engineering and operation practice of the whole network, and specifically the early detection of hidden risks and emerging troubles. Furthermore, the exploitation of certain TCP=IP dynamic behaviour, particularly the TCP control-loop, coupled with information extracted from the 3GPP layers, provides a cost-effective means to monitor the status of the whole network without requiring access to all network elements. In this article the main lessons are summarized learned from a two-year research activity on traffic monitoring and analysis on top of an operational 3G network.Keywords: traffic monitoring; traffic analysis; 3G; cellular networks; GPRS; UMTS Analyse und Monitoring von Datenverkehr in 3G Netzwerken: ein Erfahrungsbericht aus dem METAWIN-Projekt.Ein 3G-Mobilfunknetz stellt ein extrem komplexes Gebilde dar, das in ein stark heterogenes und stä ndig wechselndes Umfeld eingebettet ist. In ihm werden komplexe Funktionen der Mobilfunkü bertragung mit TCP=IP-Protokollen verbunden. Ein tiefes Verstä ndnis dieses Systems ist dringend erforderlich, aber sehr schwierig im Vergleich zu vorhandenen 2G-Netzen. Nur die kontinuierliche Beobachtung dieses modernen Ü bertragungssystems erlaubt es, sowohl die Leistungsfä higkeit des Netzes zu verstehen als auch das statistische Benutzerverhalten zu interpretieren. Die daraus gewonnenen Erkenntnisse begü nstigen sowohl eine verbesserte Netzplanung als auch einen optimalen Betrieb und gestatten es darü ber hinaus, verborgene Risiken und vorhandene Schwierigkeiten sehr frü h zu erkennen. Insbesondere erlaubt die Beobachtung bestimmter TCP=IP-Dynamik gemeinsam mit der Information, die aus den 3GPP-Schichten gewonnen wird, eine kostengü nstige Mö glichkeit, den Zustand des Gesamtnetzes zu erfassen ohne jedes Einzelelement des Netzes zu erfassen. In diesem Artikel sind die wesentlichen Erkenntnisse zusammengefasst, die in Folge eines zweijä hrigen Forschungsprojektes zur Beobachtung und Analyse eines 3G-Mobilfunknetzes gewonnen wurden.
