Abstract

As smart phone has rapidly proliferated over the past few years, LTE operators endeavor to cope with large mobile data traffic volumes. To solve such problems, we propose a new SDN-based distributed mobility management supporting distributed P-GWs and centralized control plane in LTE/EPC networks. For enhancing network performance more, we also propose a route optimization strategy for internal traffic exchanged between LTE users. The proposed solutions’ performance is compared with the conventional LTE/EPC network’s scheme in terms of the P-GW data processing volume and the number of valid data sessions. The comparison results show that the proposed solution can be an efficient way to enhance the scalability of LTE/EPC core networks.
