Abstract
Network slicing is a key technology for addressing the issue of differentiated performance requirements of diversified services in mobile networks. We focus on the radio resource allocation for RAN slicing to ensure the isolation between slices, and improve radio resource utilization. This paper proposes a radio resource allocation algorithm for Service Level Agreement (SLA) contract rate maximization. Firstly, the business parameters in SLA are mapped to the measurable network performance metrics. Then, radio resources are allocated to network slices on the basis of the collected SLA requirements. Meanwhile, Radio resources of slices that do not meet the requirements are dynamically updated without affecting the performance of slices which has met the SLA requirements, to maximize the SLA contract rate of all slices. The simulation results show that the algorithm can achieve a better SLA contract rate on the premise of ensuring isolation between slices, additionally increase the number of service users.
