Network system for transferring data efficiently and method for transferring data thereof

摘要

According to the present invention, a network system includes: a mobile station; a 5G_access point (AP) for transmitting and receiving signals to and from a wireless terminal; a 5G_eNodeB for transmitting and receiving the signals to and from the wireless terminal; an integrated gateway for transmitting and receiving the signals to and from the 5G_AP and the 5G_eNodeB; at least one intermediate router (IR) for transmitting the signals between integrated gateways belonging to different networks; and a control management server logically or physically connected to the wireless terminal, the 5G_AP, the 5G_eNodeB, the integrated gateway, and the at least one IR, which are components constituting the network, for maintaining, managing, and storing relevant information for data transmission between the components, and transmitting optimized path information to the components, in order to efficiently transmit the data in the network. According to the present invention, network resource management is easily achieved through a network system structure and a data transmission method for efficiently transmitting the data in the network, and burden on the network caused by overhead of an existing protocol, and look-up time, a table advertisement, and refresh processing of an existing router is reduced.
