Contenu (principales missions)
The Communications, Network, and Security (CNS) laboratory at THALES SIX GTS France is involved in cutting-edge IT projects aiming at the specification, design, and integration of security and computer network infrastructures for the next generation of communication systems. CNS personnel have expertise in following scientific fields: networking, especially for fixed and mobile IP network design, wireless communication systems (relaying protocols, coding, modulations, interference management, resource allocation, optimization algorithms, 5G and software defined networks), security architecture, and information systems. CNS is in charge of transferring technological and innovative building blocks to Thales’ business lines.
Nowadays, with the increasing number of connected devices and the transition to new fifth-generation cellular networks known as 5G and software-defined networks (SDNs) the essential need is to have a secure communication system with low latency, limited interference, and high connectivity. Especially in 5G networks, users or devices should have guaranteed access to available resources and different services. The slicing concept (in downlink and uplink) is one of the major breakthroughs introduced by the 5G standards that will deeply impact future communication paradigms and give users the opportunities to experience the availability of various types of services at any moment. Therefore, ensuring isolation between different types of traffic and their respective requirements in terms of throughput, delays and loss ratio has become feasible in the core and the edge of the network with the latest network virtualization trends. On the other hand, extending these defined slices with an optimized scheduler to the radio segment (RAN) and ensuring the needed security requirements for the

slices are seen as challenges. Moreover, the creation of virtual separate slices and allocation of available resource blocks over a dynamically changing wireless link remains largely unsolved. In particular in a 5G network, scheduling which is the process of how allocating available resources with an optimal algorithm between slices for transmitting data is still an open challenge.
This internship is based on theoretical studies and practical developments (or experiments). During this internship, the candidate, after a thorough state of art review and study of existing software-defined networking platforms for RAN slicing, will have to propose (or to optimize the existing solutions) and implement appropriate radio resource management and scheduling algorithms capable to offer the required quality of services and security features to the slices on the radio segment. To do so, the solution should be compliant to the proposed 5G RAN architectures, controller, and scheduler specifications.
Furthermover, ensuring the throughput optimization of existing scheduling algorithms should also be considered. The obtained solution will be validated on a local 5G prototyping platform and published in an international conference.
