The research work delves into the maturing landscape of 5G networks, with a primary focus on the critical aspect of network slicing mobility patterns. 

The dissertation centers around the challenges and opportunities within the 5G network, specifically addressing the dynamic nature of network slicing mobility patterns. The primary purpose of this research is to define and enable smooth network slicing mobility patterns, ensuring stability in both system and network resources. The study seeks to tackle the challenges arising from mobility events among mobile end-users. 

These findings align with the current discourse in the field of 5G networks, offering insights into network slicing, service isolation, and the complexities of migrating services between cloud resources and data centers. This study resonates with the growing interest in self-managed network slices within the broader communication community. 

The crux of the research lies in the comprehensive approach to network slicing mobility, addressing the intricacies of coordination between inter-cloud resources and the dynamics of inter-data center networks. The goal is to provide stable and efficient solutions for seamless service migration within 5G networks. 

The research introduces innovative strategies for automation in trigger selection, SFC migration, and the development of a network-aware agent capable of selecting accurate bandwidth values. This information can be applied to enhance and extend the notion of mobility in network slices, offering practical solutions for the deployment of 5G networks. 

As the dissertation concludes this exciting venture, it presents recommendations for advancing mobility in network slices and draws attention to unresolved questions. The research foresees future challenges and research directions, emphasizing the importance of addressing mobility issues in the evolving landscape of 5G networks.
