Broadcast and multicast services in mobile networks
Konštanský, David ; Růčka, Lukáš (referee) ; Novotný, Vít (advisor)
This bachelor studies describe differents principles and possibilities of groupsending of multimedia data in contemporary mobile network with the intention of a Multimedia Broadcast/Multicast Service in UMTS networks. This work analyse the architecture of solutions, processes of data transmission and types of coding of multimedia content of this service in UMTS networks. This paper also consider actual situation of application of Multimedia Broadcast/Multicast Service in 3G networks and offer a comparison of technologies of the standard DBV-H.

Multicast routing in UMTS technology
Kokeš, Roman ; Novotný, Vít (referee) ; Šimek, Milan (advisor)
This Master thesis is about multicast in mobile network 3rd generation UMTS(Universal Mobile Telecommunacitions System). UMTS network primary designs for data transfers and supports new services as real-time transfers of multimedia streams. This is reason why mobile network was equiped also with multicast service. When a lot of users want to receive same data (e.g. tv program) the network excessives load of transmission same data and the server have to keep connection to each user. Group 3GGP developed multicast service for UMTS, which name is MBMS (Multimedia Broadcast and Multicast Service). Thesis analyses function of this service in mobile network. First part describes basic principles of UMTS network and its structure. Next part focuses on change of main node (SGSN and GGSN) and of new node BM-SC(Broadcast-Multicast Service Center). This new node is main node for control of multicast transmission. BM-SC connects to server which provides multicast data for users and provisions individual phase of MBMS session. It was created new procedure which supports multicast session (e.g. Activate MBMS service). Next part focuses on GPRS Tunneling Protocol (GTP). This protocol is used for transfers control and user’s data in tunnels inside core network. This part describes structure of data and control messages. Last part analyzes multimedia transfers in UMTS with program Opnet Modeller.

User plane analysis in 4G mobile networks
Duda, Michal ; Krkoš, Radko (referee) ; Novotný, Vít (advisor)
The aim of the work is the mobile network LTE-EPC. You can read all about user plane and its protocol feature. This work describes procedures relating to the implementation of current services performed in the present by users in mobile networks, such as web browsing, file downloading, accessing email, watching streaming video or listening to audio. Furthermore, you can read about the proposed set of performance indicators for evaluation after qualitatively mobile network in terms of implemented services on the relations of their calculation and the appropriate way to identify the necessary parameters for the calculation. Finally, you can read about the method in which have been given sample of data from the LTE network analyzed and evaulate.
