Abstract: In the P-MP wireless data communication via relay stations, a wireless base station forms a communication schedule between the relay station and the relay station and a communication schedule between the relay station and the subscriber station. For each subscriber station (SS), a connected station, an interference at downloading, an interference at uploading, a burst profile between the BS and the SS, and a burst profile between the RS and the SS are registered in an SS management table of the BS. An interference during downloading is generated by allowing each SS to send an identifier of a BS or an RS acting as an interference to a BS to which the SS is connected. An interference during uploading is generated by allowing the BS to capture ranging fixed at the starting time and the like from an SS being under the control of the RS.

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.
