Implementation of a Mobile Communication Application for Blackberry 10 Masters in Informatics Engineering Internship Final Report Implementation of a Mobile Communication Application for BlackBerry 10 Filipe André Maia de Figueiredo [email protected] DEI Supervisor: Prof. Dr. Pedro Furtado WIT Software supervisor: Eng. Filipe Figueiredo ii Acknowledgments To my entire family, in particular to my parents, who made all of this possible. To both supervisors, Filipe Figueiredo and Pedro Furtado, for their time, patience and support during the whole internship. To Ana Carolina, my girlfriend and best friend, who always stood by me, helping me and giving me her support to overcome this journey. To all my friends and colleagues, for their support, friendship and experiences shared during the past six years. iii iv Abstract Is the smartphone an essential prop for life? Over the past few years, the number of smartphones’ users worldwide is facing an incredibly fast growth. With the smartphones evolution, applications based on Internet access have grown almost exponentially, mostly due to their minimal requirements and cost. Over The Top (OTT) applications began to appear and people started to use them to communicate instead of the traditional calls and Short Message Service (SMS). It is cheaper – most of these applications are cost free – and have more features, when it comes to comparison with the traditional mechanisms. To try to cope with the OTT usage growth, Mobile Network Operators (MNOs) came together with a solution: the creation of a solution that could compete against the OTT phenomena – the Rich Communication Suite (RCS). RCS specifies a set of communication services, including instant messaging, file transfer, real time video sharing and Voice over Internet Protocol (VoIP) calls. WIT-Software has an RCS Solution called WIT Communications Suite (WCS) that is currently available for the iOS and Android mobile platforms. With the launch of BlackBerry 10, a mobile phone that runs QNX (a Unix-like system), it is now possible to use the communication stack library developed in C++ by WIT-Software in BlackBerry 10 applications. Therefore, it is easier to bring WCS to BlackBerry 10 platform, and that is the goal of this internship. And yes! There are new props that can’t be dispensed in today’s life.

  • Illuminating the Higher Layers of Mobile Networks
    Beyond the Radio: Illuminating the Higher Layers of Mobile Networks Narseo Vallina-Rodriguez§, Srikanth Sundaresan§, Christian Kreibich§*, Nicholas Weaver§ⱡ, and Vern Paxson§ⱡ TR-14-003 December 2014 Abstract Cellular network performance is often viewed as primarily dominated by the radio technology. However, reality proves more complex: mobile operators deploy and configure their networks in different ways, and sometimes establish network sharing agreements with other mobile carriers. Moreover, regulators have encouraged newer operational models such as Mobile Virtual Network Operators (MVNOs) to promote competition. In this paper we draw upon data collected by the ICSI Netalyzr app for Android to develop a characterization of how operational decisions, such as network configurations, business models, and relationships between operators introduce diversity in service quality and affect user security and privacy. We delve in detail beyond the radio link and into network configuration and business relationships in six countries. We identify the widespread use of transparent middleboxes such as HTTP and DNS proxies, analyzing how they actively modify user traffic, compromise user privacy, and potentially undermine user security. In addition, we identify network sharing agreements between operators, highlighting the implications of roaming and characterizing the properties of MVNOs, including that a majority are simply rebranded versions of major operators. More broadly, our findings highlight the importance of considering higher-layer relationships

The telecommunications envisioned 30 years ago, when the standard was designed, industry uses a combination of 2G (GSM), 3G (Universal Mobile are no longer sufficient to ensure the security and privacy of Telecommunications Service-UMTS) and 4G (Long Term the users. Furthermore, even with the newest fourth Evolution-LTE) systems to access communication worldwide. generation (4G) cellular technologies starting to be However telecommunications industry keeps a high deployed, these networks could never achieve strong percentage of their deployed infrastructure using GSM security guarantees because the MNOs keep backwards technologies. GSM offers worldwide roaming and compatibility given the huge amount of GSM subscribers. interconnection with any available GSM network.
