無線LANシステム、アクセスポイント、端末、およびマルチキャスト通信方法

Japanese Patent JP4525340

B2

A wireless LAN system uses an address that is used by another device than terminals connected to a wireless LAN, as a multicast destination address. An access point sets an address that is used by another device than terminals connected to a wireless LAN of its own, as a multicast destination address. The access point generates a unique multicast frame, which is to be discarded by an ordinary terminal, with the multicast destination address set as a destination address according to a standard frame format, and sends the generated unique multicast frame through a wireless link. A special terminal stores the multicast destination address in advance. The special terminal receives a frame from the access point as a unique multicast frame if the multicast destination address is set as a destination address of the frame.
