Abstract: 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 UE from a gateway controller as the UE initially accesses an eNB; selecting at least one Openflow switch (OFS) for processing traffic of the UE on the basis of the information; and transmitting a request for setting a packet forwarding rule for processing the traffic of the UE to the at least one OFS.

Abstract translation: 本发明涉及一种用于有效地将软件定义网络（SDN）技术应用于LTE网络和基于该网络的系统的操作的网络结构。 因此，本发明提供了一种用于在基于SDN的无线通信网络中通过SDN控制器进行通信控制的方法，所述方法包括以下步骤：当UE最初访问eNB时，从网关控制器接收关于UE的信息; 根据该信息，选择至少一个Openflow交换机（OFS）来处理UE的业务; 以及发送用于设置用于将所述UE的业务处理到所述至少一个OFS的分组转发规则的请求。

Abstract: The present invention relates to the transmission of traffic in a mobile communication system and, more particularly, to a method and device for transmitting traffic in consideration of a quality of service (QoS) characteristic of the traffic. The purpose of the present invention is to efficiently provide a QoS differentiated according to traffic in consideration of a traffic type and a content provider in a network congestion situation of the mobile communication system.
