* ABSTRACT: Owing to a steadily increasing demand for efficient spectrum utilization as a part of the fifth-generation (5G) cellular concept, it becomes crucial to revise the existing radio spectrum management techniques and provide more flexible solutions for the corresponding challenges. A new wave of spectrum policy reforms can thus be envisaged by producing a paradigm shift from static to dynamic orchestration of the shared resources. The emerging Licensed Shared Access (LSA) regulatory framework enables flexible spectrum sharing between a limited number of users that access the same frequency bands, while guaranteeing better interference mitigation. In this work, an advanced user satisfaction-aware spectrum management strategy based on the overbooking policy in 5G networks is proposed to balance both the connected user satisfaction and the Mobile Network Operator (MNO) resource utilization. The approach is based on the MNO decision policy that combines both pricing and rejection rules under the overbooking strategy in the implemented processes. Our study offers a classification built over several types of users, different corresponding attributes, and a number of MNO’s decision scenarios. Our investigations are built on Criteria-Based Resource Management (CBRM) framework, which has been specifically designed to facilitate
dynamic LSA management in 5G mobile networks. To verify the proposed model, the results (spectrum utilization, estimated Secondary User price for the future connection, and user selection methodology in
case of user rejection process) are validated numerically as we yield important conclusions on the applicability of our approach, which offer guidelines for efficient radio spectrum management in highly dynamic and heterogeneous 5G environments.

* BIO: Zhaleh Sadreddini received the Ph.D. degree in Computer Engineering, from the Karadeniz Technical University, Turkey, in 2018. She works at the Istanbul Arel University, Turkey. She had a dissertation research opportunity during Ph.D. at the Department of Telecommunication, Brno University of Technology, Czech Republic. Her primary research interest lies in the area of resource management in next-generation cellular networks, HetNets, spectrum handoff, network slicing, big data analysis, and MCDM techniques. Her research scope also includes the measurement and prediction of end-user satisfaction with mobile data services (QoE). She is the recipient of the 2015-2016 Award of Excellence in Teaching in the Computer Engineering
Department, Avrasya University.
