PROBLEM TO BE SOLVED: To provide a network system for enabling a communication terminal to access another communication terminal within an optional IP service network or within the same network and enabling a user to select a service.;SOLUTION: This network system sets a VLAN in a user unit among a radio access point or edge switch, a relay Layer2 switch and a router. When a communication terminal is connected, an intra-network information managing device compares authentication information notified from the communication terminal with authentication information stored in an access authentication information management database, and sets a free VID as an intra-network identifier when the communication terminal is confirmed to be a legitimate user, and the radio access point or the edge switch registers the VID in a data frame sent from the communication terminal.;COPYRIGHT: (C)2003,JPO
