ABSTRACT:
An access point comprises a data table in which a correspondence relationship between a terminal ID specific to each mobile terminal and a virtual ID specific to a virtual LAN group to which each mobile terminal belongs, identifies a terminal. ID registered in a packet received from the mobile terminal, inserts a virtual LAN tag in the received packet, extracts the virtual ID corresponding to the terminal ID from the data table to register in the virtual LAN tag, and transfers it to switching means. The switching means selects an output port of the received packet based on the virtual ID registered in the virtual LAN tag of the received packet, and deletes the virtual LAN tag from the received packet and sends it.
