Outline Operations and Business Support Systems for Next Generation Networks and the IP Multimedia System This tutorial starts with a brief introduction of the ETSI TISPAN Next Generation Network (NGN) Release 1/2 and the related 3GPP IP Multimedia Subsystem Release 6/7 standard architectures. For the NGN application layer, OMA/OSE and OSA/Parlay standards for the NGN service delivery platform will briefly be introduced. Thereby, the complexity of managing NGN session control layer (a.k.a. IMS) as well as application layer architectures will be highlighted. After the requirements for NGN OSS/BSS architectures are explained, the main goals of a NGN OSS/BSS architecture will be described. Subsequently the major standards for NGN/IMS management from ETSI TISPAN, 3GPP, TeleManagement Forum will be discussed. As a conclusion of the NGN management overview, the basic current design principles, as well as future approaches will be explained. Based on this a general OSS/BSS framework for NGNs will be introduced. Solutions for open issues will be identified. These include active and passive NGN/IMS traffic monitoring, centralized traffic correlation, analysis and diagnostics, fault detection, prediction and prevention mechanisms, performance analysis, end-device-, user- and service-provisioning, backup, recovery and fail over mechanisms. Apart from these basic NGN OSS/BSS mechanisms the tutorial will explain how an NGN management architecture should support functionalities for the whole fault / shortage resolution lifecycle, so that resolution mechanisms conducted in the past will automatically aid in resolving future problems. Finally, the FOKUS Next Generation Network Business and Operations Support System (NBOSS) implemented on top of the Open IMS playground will be introduced in which major NGN/IMS management solutions mentioned before will be validated. The NBOSS Fault Management and Dynamic IMS/NGN Service Provisioning Architecture will be described in depth. Finally lessons learned from testbed deployments as well as a summary and gap analysis of analyzed NGN management standards will conclude the tutorial. Agenda

Potential Audience/Prerequisite Background The tutorial is intended for computer science and telecommunications students and engineers who have a basic background in IP networks and preferably, but not necessarily NGNs and IMS. Why the proposed topic is interesting and timely A key challenge for deploying IP-based NGN and IMS infrastructures is the provision of adequate operations and business support systems. This tutorial creates awareness of the open points in the concepts and standards and proposes relevant solutions to be taken into account when implementing NGNs and related services. Biography is professor in the electrical engineering and computer sciences faculty at the Technical University of Berlin, Germany (www.av.tu-berlin.de). In addition, he is director of the “Next Generation Network Infrastructures” division at the Fraunhofer Institute FOKUS, which also provides the national NGN platforms and applications test and development centre in Germany (www.fokus.fraunhofer.de/ngni). This testbed, covering also the famous Open IMS playground forms the basis for many R&D and industry projects performed for many international vendors and network operators. In addition, Prof. Magedanz is extraordinary professor at the universities of Pretoria and Cape Town in South Africa and the Waterford Institute for Technology in Ireland. Prof. Magedanz is senior member of the IEEE, editorial board member of several journals, and the author of more than 200 technical papers/articles. Based on his 17 years of experience in teaching complex IT and telecommunication technologies to different customer segments in an easy to digest way, he is a globally recognised technology coach. is a research graduate with Prof. Thomas Magedanz and finalizing PhD on Next Generation Network Operations Support Systems at the Technical University of Berlin, Germany. He received his "Master of Science in electrical engineering” from the Technical University of Berlin in Germany. He has been working for the Fraunhofer Institute FOKUS for the last 5 years. His major area of expertise is applications and media for Next Generation Networks, signaling protocols in IP-based networks as well as mobility and positioning mechanisms for mobile agents. He worked in national and international research projects and is currently designing and implementing IMS based solutions for major German mobile operators, carrying out consultancies and investigating future NGN management solutions. He is the author of several research papers and journals and frequently presents latest achievements in the field of IMS and NGN at international conferences.

Outline Planning wireless cities based on WiFi-WiMAX mesh networks-technologies, business models and applications - Half-day Turorial. The objective of this tutorial is to address the most important aspects of planning, building and operating wireless infrastructures for digital communities based on the novel Wi-Fi and WiMAX mesh network technologies. Providing broadband access to citizens, communities, public institutions and developing businesses has become a strategic objective for governments worldwide, in particular to solve the “digital divide” problem. Building and operating broadband network infrastructures by public participation is essential for creating the right telecommunication environment for digital ecosystems, in particular to involve small-to-medium enterprises. Although a large number of initiatives, called community networks or municipality networks, or digital cities have been launched worldwide, finding suitable technology solutions and business models are not at all straightforward tasks. As for the technology, in principle there is a variety of systems already widely used by telecom companies, but they are not optimal for deployment and operation by local government for various technical and regulatory reasons, and also the associated costs could be prohibitively high. New wireless technologies have been emerged during the last couple of years that are particularly suitable for implementation by different communities and public administrations. These technologies, that include Wi-Fi mesh networks, fixed and mobile WiMAX systems and their combinations, offer flexibility in installation as opposed to fiber or copper based infrastructures, require significantly less investment, and can operate also in license-free frequency bands. Therefore, it is not surprising that many government subsidized pilot projects have been recently implemented worldwide. The talk will demonstrate some of the interesting examples including testbeds developed by the authors.
