The goal of this project was to analyze the IP Multimedia Subsystem (IMS) with respect to the interworking functionality between two or more IMS domains belonging to different operators. The thesis presents an overview of IMS, its purpose, the circumstances and the environment in which it has evolved, and a look into some of the challenges that lie ahead. Through careful examination of the history of the mobile communications and of IMS itself, the thesis attempts to give the reader a full and comprehendible understanding of what IMS is, what its purpose is, and why it came into existence.

Abstract:

Nowadays, the long-term identifier of a user in a mobile network, namely International Mobile Subscriber Identity or IMSI, is transmitted in clear text over the radiointerface. Given that this interface is used as a shared medium, anyone with a radio transceiver and processing software can thus read such identifier. This fact constitutes a threat to user privacy, considering that the user is traceable by following the presence of the identifier in the network. Moreover, the menace has been known in the literature for the last 25 years, but no countermeasures have been deployed because the seve

Atuadores de pilha piezelétricos são usados para exercer as forças de controle na estrutura, os quais substituem barras inteiras ou somente uma parte delas. Estes tipos de atuadores, também, satisfazem a necessidade de obtenção de estruturas leves. O posicionamento ótimo desses atuadores

Abstract:

Hasta hace un par de décadas en el IMSS se utilizaban sistemas tradicionales, en los que los documentos en papel eran almacenados en archivadores utilizados para mantener los documentos organizados y donde los empleados podían encontrarlos “fácilmente”, esto claro si el empleado mantenía una buena organización y clasificación de estos. Derivado de lo anterior en el año 2009 en el IMSS fue desarrollado e implantado un sistema informático llamado SIMF (Sistema de Información de Medicina Familiar) que es el Expediente Clínico Electrónico dentro del Instituto y que es la piedra angular dentro de

Abstract:

With the rapid development of telecommunication industry, the IP multimedia Subsystem (IMS) could very well be the panacea for most telecom operators. It is originally defined as the core network for 3G mobile systems by the 3rd Generation Partnership Project (3GPP), the more recent development is merging between fixed line network and wireless networkd This report researchs the characteristic of the IMS data and proposes an IMS characterization analysis. We captured the IMS traffic data with 10 tousands users for about 41 hours. By analyzing the characteristics of the IMS, we know that the mo

Abstract:

Conformance testing is the process of checking that a system possesses a set of desired properties and behaves in accordance with some predefined requirements. In this context, passive testing techniques are used when the system under test cannot be interrupted or access to the system's interfaces is unavailable. Passive testing relies on the observation of the implementation during runtime, and the comparison of the observation with the expected behavior, defined through conformance properties. The objective of this thesis is to define a novel methodology to validate communicating protocols b

Abstract:

<p>Today, there are still different technologies used in fixed and mobile networks environment such as cellular technologies (GSM, UMTS, 3G, etc.), wireless network technology like WLAN, wired network technology like ADSL, etc. With the usage of IMS (IP Multimedia Subsystem), all those technologies can be combined together in a fixed mobile convergence environment based on an IP-based infrastructure. Although IMS applies well for a Fixed Mobile convergent environment, there are still issues that need to be solved. First, the IMS central protocol is SIP but there are differences between the 3GP

Abstract:

Mestrado em Engenharia Electrónica e Telecomunicações<br>As Redes de Próxima Geração ou NGN (Next Generation Networks) representam um novo conceito de rede que consiste na convergência da voz, dos dados e de novas aplicações multimédia. As vantagens são obvias, a NGN consegue associar a redução dos custos operacionais das redes de operador ao incremento da possibilidade de geração de novas fontes de receita, pois torna possível oferecer uma grande diversidade de serviços multimédia. No entanto, para que tal aconteça, torna-se essencial a existência de arquitecturas de rede que sejam ext

Abstract:

One of causes of increased latency service over the whole IMS network can be unbalanced SIP (Session Initiation Protocol) signalling traffic through CSCF (Call Session Control Function). This thesis is devoted to the proposal of weight-based load balancing algorithm which can be used for the S-CSCF assignment performed by I-CSCF during the initial registration procedure of subscribers over the IMS architecture. The designed mechanism is implemented and evaluated in the mathematical model of IMS subsystem based on single servers with FIFO queues with the unlimited capacity in the numerical comp

With the growing demand for mobile networks and specially IPMultimedia subsystem (IMS), new cloud native orchestration tools providing more flexibility and efficiency start to be used within telecommunication companies in order to improve the robustness and the reliability of these systems. However, Kubernetes, the most used among cloud native orchestration tools does not fulfill completelyall the needs and use cases in terms of networking the telecommunication industry meets.

Includes bibliographical references (leaves 72-76).<br>Rapid increase in bandwidth and the interactive and scalability features of the Internet provide a precedent for a converged platform that will support interactive television. Next Generation Network platforms such as the IP Multimedia Subsystem (IMS) support Quality of Service (QoS), fair charging and possible integration with other services for the deployment of IPTV services. IMS architecture supports the use of the Session Initiation Protocol (SIP) for session control and the Real Time Streaming Protocol (RTSP) for media control. This
