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.

The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation
Machová, Petra ; Kosová, Jaroslava (referee) ; Čech, Josef (advisor)
The topic of the diploma thesis „The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation “ is a draft and appraisal of four variants of thermal insulation of the building. The thesis deals with the assessment of the current proposal for apartment building envelopes along with proposing alternative plans with emphasis on reducing heating costs. The first section describes the types of buildings according to heating demand and a list of different variants of thermal insulation materials. The second part is devoted to a specific apartment building in the Ústí nad Labem for which there are designed in four variants of insulation. The work includes thermal assessment in original condition and the assessment of new condition modified by adding thermal insulation. Through research will bedetermined price of implementation of proposed insulation options together with the costs of operation of the apartment building. In conclusion, the diploma thesis evaluates the payback period of insulation.

Multifunctional family house
Vdoleček, Jaroslav ; Stodůlka, Jindřich (referee) ; Sukopová, Dáša (advisor)
The goal of this bachelor project is to design a multifunctional family house with a service of a lawyer´s office. The house is designed as a brick house made of clay blocks Porotherm profi. Horizontal bearing structures are made up of reinforced concrete slabs. Footings are designed as unreinforced. The building has a rugged floor plan with 2nd floor in a residential part. The whole object is completed by a flat roof with parapet. A garage with parking place for two cars states cars and small garden equipment is also part of family housing. Law firm Lawyer´s office has its own independent entrance next to the entrance to the house.

5G Cellular Networks
Schaller, Lukáš ; Novotný, Vít (referee) ; Krkoš, Radko (advisor)
The subject of the bachelor’s thesis is mobile communication network of 5𝑡ℎ generation with focus on improvements from current 4𝑡ℎ generation. At the beginning of my work I summarized the system of 4𝑡ℎ generation mobile network EPS including description of individual parts. Next section pays attention to 5𝑡ℎ generation mobile communication network in context of network demands and future development, radio interface, network architecture or Internet of Things. Next follows solution of D2D communication especially LTE Direct and Wi-Fi Direct technologies. Here I paid attention to data agregation used in conjunction with Internet of Things enabling usage of IEEE 802.11 or IEEE 802.15.x standards. In closing part I described heterogeneous radio network and in particular mutual integration of cellular and Wi-Fi networks. In the first practical part of my bachelor’s thesis I measured parameters of Wi-Fi network during client-server communication. In the second practical part I tested data agregation of two devices using experimental network at Institute of communication.

The impact of executing new thermal insulation on an administrative building in Blansko on the expenses associated with its operation
Kopřivová, Petra ; Bradáč, Albert (referee) ; Čech, Josef (advisor)
The topic of the diploma thesis „ The impact of executing new thermal insulation on an administrative building in Blansko on the expenses associated with its operation“ is a draft and appraisal of four variants of thermal insulation of the building (EPS, EPS G, Mineral wool, Phenolic foam). It deals with an actual building situated in Blansko. All the variants are projected according to the same technical specifications (thermal transmittance) and their thermal parameters, technical parameters and the rate of return have been assessed. The assessed building (The A building) is at rectangular shape. It has six above - ground floors and a basement, it contains mainly administration sites. The construction system is concrete frame, which has curtain wall made of perforated blocks with thickness 250 mm. The building has got reinforced concrete floors, the roofing is made of double-skin roof construction. The supply for heating is a separate gas boiler room.

Quality of Service in Cellular Networks
Spiššák, Filip ; Mašek, Jan (referee) ; Krkoš, Radko (advisor)
This thesis deals with the quality of service (QoS) mechanism in Evolved Packet System (EPS). The basic architecture and characteristics of the EPS are introduced. The concept of QoS is defined. Furthermore, QoS related entities, their functions and corresponding procedures are described. The methodology for measuring and evaluating of end-to-end QoS as seen from a user’s point of view is designed. This methodology is used to measure QoS of experimental cellular network at UTKO FEEC BUT. Finally, configuration change for optimizing the QoS support of experimental cellular network is designed.

Technology for comprehensive support of multimedia services in heterogeneous networks
Dosoudil, Petr ; Krkoš, Radko (referee) ; Novotný, Vít (advisor)
The theses explains the Evolution Packet System (EPS) and subsystem IP Multimedia Subsystem (IMS). It also informs how these systems cooperate and through which interfaces the main data and signals between these two technologies are transfered. The thesis includes practical section, in which installation and configuration of sections of the IMS system including its "core", and application and medial server. For verification of the functionality of the system, two dissimilar clients are installed, and emulator WAN is applied for simulation of Internet. The product of the theses is the design of the laboratory exercise drafted in such a way that it can be solved by students less knowledgeable of the issues.
