Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments herein achieve a method for authenticating access in a mobile wireless network system. The method includes receiving by an Extensible Authentication Protocol (EAP) authenticator an EAP packet encapsulated from an access terminal over a high rate packet data radio link and a signaling interface through a radio access network. The EAP packet is encapsulated over at least one of a Non-Access Stratum (NAS) interface, a Radio Resource Control (RRC) interface and a N1 interface. The EAP authenticator is located at a secured node in a core network of the radio access network. Further, the method includes authenticating by the EAP authenticator at least one of a network access subscription and a service of the access terminal.
