Abstract


A unified mapping framework called resource scalability collaboration (RSCMF) is proposed, which jointly optimizes heterogeneous radio access networks and provides customized service applications. To support resource scalability collaboration, infrastructure is virtualized into network functions (VNF) by virtualization technology and software defined radio. To support the loose coupling of applications and infrastructure, based on VNF, logical mapping and physical mapping are applied. The logical mapping implements customized function for the application by quantitative analysis decision tree and virtual function orchestration. The physical mapping optimizes the global performance via scalable resource collaboration. We present the architecture, design challenges, and key technologies of RSCMF through our initial research efforts and illustrate how to use resource scalable collaboration to maximize the resource utilization. We also provide examples of logical and physical mapping based on traffic load and energy consumption and quality of service, when topology changes dynamically.
