A network system for interworking a Wireless Local Area Network (W-LAN) and a 3rd-Generation (3G) mobile communication network through a Radio-over-Fiber(RoF) link and an authentication method in interworking in the network system are provided. The network system includes a 3G mobile communication network and a W-LAN system. The 3G mobile communication network includes a voice signal processing network connected to a Public Switched Telephone Network (PSTN) for voice call processing with respect to a predetermined mobile terminal, a packet data network for data communication with the predetermined mobile terminal, and a terminal device for communication with the predetermined mobile terminal. The W-LAN system is connected to the packet data network of the 3G mobile communication network to provide a W-LAN service to the predetermined mobile communication terminal. The W-LAN system is implemented in a plurality of Base Transceiver Stations (BTSs) included in the 3G mobile communication network through the RoF link.
