Integrated network system for automobile and gateway therefor

An integrated network system for automobile and a gateway therefor are provided to enhance efficiency of networks by managing and controlling various equipments supporting heterogeneous protocols by using a mobile terminal that supports a Bluetooth protocol and monitoring and diagnosing various states of the interior of a vehicle. Devices(10) support MOST(Media Oriented Systems Transport), Bluetooth, CAN(Controller Area Network), LIN(Local Interconnect network), and Flexray protocols or an ethernet protocol. Gateways(20) converts the MOST, Bluetooth, CAN, LIN, Flexray protocols or the ethernet protocol based on the MOST protocol. A MOST backbone(30) provides a duplexed network line based on the MOST protocol between gateways(20). The devices(10) are connected with the MOST backbone(30) through the corresponding gateways(20).
