IMS aplication creation
Nagy, Ľuboš ; Novotný, Vít (referee) ; Mácha, Tomáš (advisor)
This thesis describes basic principles of IP Multimedia Subsystem, known as the IMS, and shows the possibility for design applications using IMS. Firstly, a generic architecture IMS as layer model divided into four logic layer with definition the interfaces and the main entities is described. The IMS is based on SIP and IP protocols. Then is the architecture of SIP with the main entities explained. Structure of packet, request and response method in the part of SIP is also described. After that, three network services, namely presence services, instant messaging services and push over cellular services are presented. For each services the figuration of their architecture and the basic definition of their main entities are shown. Moreover, the graphical diagrams of SIP signalization are depicted for these services. In the next chapter, the self implementation of services was designed, namely presence services and services for speech transmission with next secondary function as sending email with registration information of user. The project was designed as client - server application in the development studio SDS Ericsson 4.1. The client application was simulated as java application and also as an application for Symbian emulator. The process of client registration was performed with the help of ICP platform. Finally, the diagram of analysis communication client - server is displayed with the captured packets explanation by the help of network analyzer WireShark. The video files, which were specially created for this thesis showing presentations for presence services and sending email. The most important results are summarized in the end of this article.

Design and development of application for position monitoring
Kovář, Petr ; Šilhavý, Pavel (referee) ; Krajsa, Ondřej (advisor)
The aim of the master’s thesis was to implement in the C++ language a software solution of the localization of the mobile phone with Symbian OS in the GSM network. The intended purpose of this solution would be especially the phone localization in the case of its theft or loss. A familiarization with the development process of the Symbian platform and understanding the features of the Symbian version of the C++ language preceded the realization itself, because the Symbian C++ has an original style of the memory manipulation and error handling. The Symbian C++ basic principles and its features used in the implemented software are described in the second chapter of the text part, the first chapter deals with the history and version structuring of the Symbian OS. In the third part of the text is described the created software. The realized solution consists of three parts – server application PhoneLocServer for a mobile device, client application PhoneLocClient for a PC and the web-located part. The server was developed for the Symbian OS in the C++ language in the IDE Carbide.c++ and was tested in the S60 3rd edition SDK MR emulator and on the real device Nokia N73. It is a GUI-less application running in the background, which is run automatically after a smartphone start-up. It controls the incoming SMS over the socket listening and the messages addressed to itself processes before a user can notice them. The control messages body is comprised of a prefix, which identifies them, a password, a sending period value and a state to which application should change. After the receiving of the control SMS server verifies the SMS sender through the use of his telephone number and the password. It compares these values with the data stored for the given IMEI on the web server. If the verification succeeds, the server runs a timer with the period known from the control SMS and on the callback of this timer are transferred the data describing current phone location and state via HTTP protocol to the web server. The GSM localization method “Cell ID” is used for the location determination. After the client user asks for the start of loading the data, he must answer the password and the observed phone’s IMEI and he is verified through the use of the web server again. If the verification succeeds, the periodic download of the server data starts and from the first downloaded file is found out the upload period. Download then continues till the time the client detects the end of sending by the server part or till the client user stops the download himself. The client was developed in the C++ language in the C++ Builder environment. It requires a Windows OS and internet connection for its right function. The web server mediates communication between the server and the client, stores the data for user verification and makes possible the server-side upload by the help of a simple PHP script. In all the used web server directories is present the .htaccess file to improve its security, e.g. it denies the directory listing in a web browser.

Mobile Devices Attacks
Trebula, Peter ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
Táto práca sa zaoberá bezpečnostnými architektúrami v mobilných zariadeniach a rôznymi formami útokov proti nim. V prvej časti je úvod do bezpečnosti mobilných zariadení a bezpečnostné riziká súvisiace s mobilnými zariadeniami. Sú tu uvedené slabé miesta vo WLAN sieťach a úvod do Bluetooth technológie aj s rizikami. V druhej časti je predstavenie produkčného testovania, ktoré sa využíva u spoločnosti Nokia a popis jednotlivých testov používaných na vyskúšanie funkčnosti zariadení. Rovnako sa v nej nachádza popis architektúry, ktorou sú mobilné zariadenia u spoločnosti Nokia zabezpečené voči rôznym formám útokov viažucim sa na inštalovanie softwaru a testovanie.

Chat system for mobile phones
Starosta, Michal ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
The aim of this master’s thesis is design and implementation local chat system for mobile devices and smartphones. System contains main server, witch covers communication with application for smartphones and web server, witch covers communications with browsers and presentation application, witch goal is to presenting chat to area. Smartphone ap- plication is crated for Android, iOS, Windows Mobile and Symbian operating systems. Wifi network is used for communication and message sending and signal coverage area defines local chat. Messages are shown dynamically and it’s possible send them as user status to Facebook social network.

IS for Phone Calls Accounting
Šitka, Petr ; Ráb, Jaroslav (referee) ; Ščuglík, František (advisor)
This contribution refers to development of information system working with mobile communication devices. The information system is mainly for collecting and analyzing data made through the mobile devices. In the contribution there are described possibilities of connection between PC and mobile device, also there are described the most common information system for mobile devices, and tools for application development. Design and implementation of information system is based on this study.

Innovative User Interface for Smartphone
Utěkal, Jan ; Herout, Adam (referee) ; Beran, Vítězslav (advisor)
This bachelor's thesis presents innovative user interface for Symbian S60 5th edition operating system. It describes the process of development of an innovative control of a cell phone. It outlines the tasks and designs the solution from partial thoughts to the final form of a control component. The purpose of the component is simplifying the work with the device and improving its efficiency. The text also covers the implementation details for Symbian C++ programming language and results of experiments on a group of users. The whole topic is enclosed by discussion about the future development of the project and its possible usage.
