Proposal for a Teaching Solution for Mobile Telecommunications 4G/5G and Associated Services in Virtual and Digital Universities

The transition to 5G, the development of virtualization and cloud solutions, and microservices approaches through containerization offer new opportunities for telecommunications education, particularly in regions like Senegal. This article proposes a microservices-based approach to implement VoLTE and VoNR services at the École Centrale de Logiciels Libres et de Télécommunications in Dakar. A testbed with a containerized 4G/5G core network, srsRAN base stations, and a Grafana monitoring system enables practical voice service testing with performance comparable to commercial networks. Resource challenges have been overcome through the use of open-source technologies, providing a sustainable and adaptable educational model for African contexts. This study contributes to improving telecommunications education in Senegal and serves as a roadmap for the adoption of 5G technologies by other African institutions. Future work will integrate IoT and critical communications into the educational framework.
