SDN integration in LTE mobile backhaul networks

摘要: The major challenge in future mobile networks is how to improve throughput support the increase demand traffic. Software Defined Networks new technology proposed but so far it has been be integrated current 4G architecture without changes. However, we present beyond where Network should used a more disruptive approach redesign architecture. This proposal includes proper migration path ensure reasonable transition phase. objective not meet short term needs fulfill requirements by revamping transport network backhaul, and moving most of LTE elements cloud. In this remove completely core as known today. Instead, consists simplified access formed base stations i.e. eNodeBs, interconnected through backhaul composed SDN switches managed from cloud together with rest elements.
