Emergency Button for Seniors
Verbík, Josef ; Chmelař, Milan (referee) ; Strašil, Ivo (advisor)
This Thesis „Emergency Button for Seniors“ is about suggestion of realization of system emergency signalization. The System consists of programmable digital watch with wireless interface and PC with software processing signals. Status signalization is created by phone message and figuration of dialog on monitor. There is used free software for realization. Operation system on PC is Linux (distribution Ubontu 11.04). For graphic transitional plane PC application is used cross-platform framework QT. For watch firmware is used C compiler MSP430-GCC, MSP debug v0,15 and firmware OpenChronos.

Home security system - remote access module
Šarda, Petr ; Bradáč, Zdeněk (referee) ; Fiedler, Petr (advisor)
This thesis deals with remote access module for electric security systems (ESS). The design is based on valid standards that apply to a production of electric security system. It includes a design of module connection to the central that controls the module. There is also a communication protocol for connection with the central and with the user. The last step is development of web interface, which is realized on the selected development kit.

Mobile Switching Centre Emulator
Králíček, Jan ; Ráb, Jaroslav (referee) ; Ščuglík, František (advisor)
This thesis attempts to provide basic overview of the topic of the GSM system and tries to design Mobile Switching Centre Emulator that could perform the operation Location Update. The first part of this thesis describes the principles and specifics of the GSM network (network structure, the operations required to support user mobility, network entities, etc.). The second part of this thesis describes the SS7 signaling protocols, SIGTRAN and MAP protocol. The final part deals with design of the emulator.

Prediction and analysis of traffic crossings using machine learning
Hlaváček, Jakub ; Frýza, Tomáš (referee) ; Götthans, Jakub (advisor)
The thesis focuses on the area of traffic control, specifically traffic control of intersections, especially control technologies based on the obtained traffic data. The main goal of the work is the design and subsequent implementation of a real intersection Anenská and Capt. Jaroše, Pardubice in the form of a model. The work also deals with the demonstration of the used signal programs of junction control through the created model. The model is assembled from a wooden base and smaller parts are made by 3-D printing. The unit is controlled by an Arduino microcomputer. In creating this thesis, I managed to understand the comprehensive traffic management in today’s cities, which requires the current traffic situation.

Converged solution of speech services
Mácha, Tomáš ; Kovář, Petr (referee) ; Novotný, Vít (advisor)
Development in VoIP technology is connected with the rapid growth of quality and data rate of the Internet connection. The application of the VoIP technology has become one of the key areas in telecommunication and networking. The main task of this thesis was to explore the questions of IP telephony and voice transmission over data networks according to H.323, SIP and Cisco architectures. Next focus was on designing and implementing experimental workplaces of mentioned architectures and their converged solutions. The purpose of the first chapter is to introduce the theory background of architectures required for implementation of real-time services in data networks and their comparison. The key objectives of the second and third part are to design and implement experimental workplaces containing signaling and proxy servers and hardware or software IP phones of several architectures. Illustration examples of different network topologies are included to demonstrate designed and realized VoIP solutions. Several tests of established communication are done using a packet analyzer. These tests examine duplex data transmission over IP. This article also contains two laboratory exercises designed according to gained practical experiences. The laboratory exercises provide an overview of theory and clearly indicate the possibilities of IP telephony.

Control Procedure Analysis in EPS-IMS Networks
Šubrt, Jan ; Červenák, Rastislav (referee) ; Novotný, Vít (advisor)
The master thesis is focused on control procedures in EPS-IMS networks. Firstly the thesis describes systems IMS and EPS. The second part of thesis includes the theory of control procedures in EPS such as cell acquisition, random access procedure, identification of subscriber, authentication of subscriber, security procedures, tracking area procedure, default bearer creation, implementation of CSFB procedure and detach procedure. Processes related to subsystem IMS such as registration to IMS, bearer creation for IMS signalling and voice service VoLTE are the next part of thesis. The next main topic is the VoLTE implementation problematic and VoLTE cooperation with diverse terminals. There is also explained the principle of Circuit Switched Fallback for realization voice services in EPS without VoLTE service. All procedures mentioned above except of procedures which are related to IMS were captured and analyzed using software Wireshark and QualiPoc. The final part of the thesis is lab task creation based of the analyzed messages.

Význam a organizování služby pátrání a záchrany v civilním letectví
Albastová, Slavěna ; Balážová, Renáta (referee) ; Chlebek, Jiří (advisor)
A comprehensive survey including concise attributes of methods and procedures being used during search and rescue operations on the territory of the Czech republic are the main purpose of this bachelor thesis. The search and rescue operations create one part of commitments resulting from the membership of the Czech republic in the ICAO International Civil Aviation Organization. This thesis is regarded as a study guide for future professional pilots obliged to get through their examination of ÚCL (Úřad civilního letectví).

Analysis of control traffic in mobile networks
Šubrt, Jan ; Krkoš, Radko (referee) ; Novotný, Vít (advisor)
The Bachelor´s thesis describe management procedures in mobile systems. This thesis is mainly focused on mobile systems GSM and LTE. Further are describe basic processes what are required before starting service. This basic procedures contains: inspection of radio signals, select the cell with the best parameters for connection, allocate channel to mobile station, authentication of subscriber and location update. Next part of thesis describe procedures in handover, initialize call session and data session. Last chapter describes laboratory task for subject Communication resources in mobile networks.

Signalling Transmission for Internet Television
Burget, Radim ; Makáň, Florian (referee) ; Vodrážka,, Jiří (referee) ; Komosný, Dan (advisor)
A signalization in an Internet protocol environment is commonly used for monitoring quality of service and other parameters of a network. This thesis is involved in transmission of signalization through internet protocol networks and proposes scalable solution for small and even for large-scale internet television broadcasting. The main contribution of this thesis lies in design and validation of optimal hierarchical tree on the basis of resources assigned. This is done in respect to geographical distance, network distance of each particular member of the hierarchical structure. For the design of algorithms simulations and global experimental network were used.
