Sdn based lte network structure and operation scheme

摘要

The present invention relates to a network structure for effectively applying a software defined networking (SDN) technology to an LTE network and an operation of a system on the basis of the same. The present invention therefore provides a method for controlling communication by an SDN controller in an SDN based wireless communication network the method comprising the steps of: receiving information on a terminal from a gateway controller as the terminal initially accesses a base station; selecting at least one open flow switch (OFS) for processing traffic of the terminal on the basis of the information; and transmitting a request for setting a packet forwarding rule for processing the traffic of the terminal to the at least one OFS.
