A method and system for bundled authentication of wired or wireless terminal between service and access networks in NGN environment are provided to perform the NACF-SCF(Network Attachment Control Functions-Service Control Function) bundle authentication in NGN regardless of wireless and wired access. The NGN(Next Generation Network) terminal unit(10) comprises a WLAN(Wireless LAN) terminal(101), a WiBro terminal(102), and a cable terminus(103) and an ADSL (Asymmetric Digital Subscriber Line) terminal(104). A connection unit(11) comprises an AP(Access Point)(111) connected to the WLAN terminal, an RAS(Remote Access Server)(112) connected to the WiBro terminal, and a CM(Cable Modem) part(113) connected to the cable terminus. The ADSL terminal is connected to wired and wireless network(16) through the ADSL circuit. A NACF(Network Attachment Control Functions) part(12) which is the access control network performs the IP address assignment and the access authentication. The SCF(Service Control Function) part(13) which is the service control network performs the service routing and service certification. The bundle authorization control server(14) exchanges the authentication information between the SCF part and the NACF part. The service user ID corresponding to the subscriber identification is stored in the bundle authorization control server.
