METHOD AND SYSTEM FOR BUNDLE AUTHENTICATION OF WIRED OR WIRELESS TERMINAL BETWEEN SERVICE NETWORK AND ACCESS NETWORK IN NEXT GENERATION NETWORK

PROBLEM TO BE SOLVED: To provide a method and system for bundle authentication of a wired or wireless terminal between a service network and an access network in a next generation network.SOLUTION: A method of authentication processing of a node (S-CSC-FE/I-CSC-FE (Serving Call Session Control Functional Entity/Interrogating Call Session Control Functional Entity)) within a service network for bundle authentication between a service network and an access network includes: receiving first authentication information about access authentication of a terminal from a first node included in the service network; making a request to receive second authentication information from a second node within the service network on the basis of the first authentication information; and comparing the first authentication information with the second authentication information to authenticate the terminal.
