In this topic an analysis of RRC messages in 4G and 5G should be done. There exist several different kind of these messages with different functions and level of information content. The focus should lay on messages related to the connection release. The analysis should consider privacy and security aspects. After the theoretical review and analysis the practical part should focus on an attack. An implementation of one security and privacy aspect should be done as a proof-of-concept with Open Source hard- and software.

The following things are requested to be designed, implemented, and evaluated (most likely via proof-of-concept) in this thesis:
• Security and availability analysis of specific RRC messages
• Implementation of an attack

Optimal Placement of MAF chains considering Priority

Channel Description for Wireless Access Systems.

In future communication systems such as 6G, in-network computing will play a crucial role. In particular, processing units within the network enable to run applications such as digital twins close to the end user, leading to lower latencies and overall better performance. For this, the execution location of these applications should be changed dynamically according to the available networking resources.

 In this thesis, the task is therefore to develop and evaluate an approach to optimize the migration of medical applications, i.e., modular application functions (MAFs), when executed in the network. The challenge of this migration lies in the connection quality during the migration and the migration of stateful applications, i.e., using memory.

 The result will be an evaluated placement approach for applications in the medical environment considering the availability.

For that, suitable real use cases are identified together with our partners at MITI (Hospital "Rechts der Isar"). The optimizing approach then leads to a specified distribution of the processing and networking resources, satisfying the minimum needs of critical applications while considering the needed availability.

Containerizing the ROS2 components according to the MAF concept.

6G soll als neuer und zukünftiger Mobilfunkstandard den Menschen in den Fokus rücken. Neben sehr geringen Latenzen und extrem großen Datenübertragungsraten wird das Netzwerk zuverlässiger, sicherer und dynamischer. Diese Eigenschaften sind besonders in der Medizin und der Medizingerätetechnik gefragt, um intelligente Datenübertragung zwischen Geräten und Menschen zu ermöglichen. Im Rahmen des Verbundprojektes „6G-life“ sollen zwei medizinische Demonstratoren entwickelt werden, die diese Netzwerkeigenschaften untersuchen. Ein Demonstrator ist ein robotisches Telediagnostiksystem zur Remote Untersuchung von Patienten. Ein zweiter Demonstrator beschäftigt sich mit der raumadaptiven Erfassung von Vitalparametern.

Ziel der Forschungspraxis ist die Ermittlung von medizintechnischen Anforderungen an die Netzwerkkommunikation hinsichtlich der Ausfallsicherheit. Dies beinhaltet eine Recherche gängiger Normen und Richtlinien, die bei der medizinischen Datenübertragung berücksichtigt werden müssen, sowie Maßnahmen, die zur Sicherstellung zuverlässiger Kommunikation getroffen werden können. Darüber hinaus sind Interviews mit Medizinern wünschenswert, um die Nutzerseite zu berücksichtigen.

Im Rahmen der Arbeit sollen folgende Punkte behandelt werden:

• Recherche zu gängigen Richtlinien und Mechanismen, die in der medizintechnischen Netzwerkkommunikation zur Ausfallsicherheit eingesetzt werden.
• Interviews mit Klinikpersonal
• Evtl. Messung mit den vorhandenen Testbeds

Diese FP wird in Kooperation mit unseren Partnern der MITI Gruppe am Krankenhaus "Rechts der Isar" durchgeführt.

• Motivation
• Interesse an Medizintechnik
• Deutsch (zwingend erforderlich zwecks der Interviews)
• Grundlegende Kenntnisse über Netzwerkkonzepte

Future medical applications put stringent requirements on the underlying communication networks in terms of highest availability, maximal throughput, minimal latency, etc. Thus, in the context of the 6G-life project, new networking concepts and solutions are being developed.

For the research of using 6G for medical applications, the communication and the medical side have joined forces: While researchers from the MITI group (Minimally invasive Interdisciplinary Therapeutical Intervention), located at the hospital "Rechts der Isar", focus on the requirements of the medical applications and collecting needed parameters of patients, it is the task of the researchers at LKN to optimize the network in order to satisfy the applications' demands. The goal of this joint research work is to have working testbeds for two medical testbeds located in the hospital to demonstrate the impact and benefits of future 6G networks and concepts for medical applications.

Your task during this work is to implement the communcation network for those testbeds. Based on an existing open-access 5G network implementation, you will implement changes according to the progress of the current research. The results of your work, working 6G medical testbeds, will enable researchers to validate their approaches with real-world measurements and allow to demonstrate future 6G concepts to research, industry and politics.

In this project, you will gain a deep insight into how communication networks, especially the Radio Access Network (RAN), work and how different aspects are implemented. Additionally, you will understand the current limitations and weaknesses as well as concepts for improvement. Also, you will get some insights into medical topics if interested. As in such a broad topic there are many open research questions, you additionally have the possibility to also write your thesis or complete an internship.

Most important:

• Motivation and willingness to learn unknown things.
• Ability to work with various partners (teamwork ability).

Of advantage:

• C/C++ and knowledge about how other programming languages work (Python, etc.)
• Knowledge about communication networks (exspecially the RAN), 5G concepts, the P4 language, SDN, Linux.
• Initiative to bring in own ideas and solutions.

Please note: It is not necessary to know about every topic aforementioned, much more it is important to be willing to read oneself in.
