PROBLEM TO BE SOLVED: To perform specification/authentication of an access line with a simple mechanism without depending on an IP version, in a network in which connection source information is dynamically allocated.SOLUTION: An access NW apparatus 13 permits connection of a user terminal device 16 and transmits an address allocation request to an address allocation device 14 when an MAC address of an HGW 12 is not disguised. The address allocation device 14 allocates an address to the HGW 12 and transmits allocated address information to an access line specification/authentication device 15 during advance preparation. The access line specification/authentication device 15 registers association information of the allocated address information and user basic information, receives a line authentication request from a service providing server 19 when performing line authentication, checks a disguised address and a line using the association information and an address stored in an edge rooter 17, and returns its result to the service providing server 19. |
