Growing popularity of smartphones and tablet computers is making increase of signaling and processing load on mobile core networks. As one of the effective solutions for the growth of the processing load in LTE Networks, virtualization of functional components of the core network has been studied. Such a network virtualization simplifies the management of the networks and improves efficiency and fault tolerance of the cellular networks. However, the processing overhead of the virtualization lowers the network performance. In this paper, in order to minimize the overheads of the virtualization, we propose a novel method to optimize allocation of the virtual functions to the mobile core networks. We formulate an objective function of the total signaling and processing time, and minimize it by an optimization algorithm to find best allocation of the virtual functions to the physical servers. Our computer simulation results show that the proposed scheme reduces the processing time by optimized allocation of the virtual functions. |
