摘要： A subnet realization method in a home network system is provided to allocate a different band group from an existing cell when performing communication between devices belonging to the cell managed by a home AP(Access Point) in ubiquitous environment, thereby more increasing frequency usage efficiency. A cell AP(221) transmits a beacon signal to devices(31,32) to set a wireless path(S10). If the devices(31,32) demand subnets to the AP(221) for mutual communication(S11,S12), the AP(221) searches valid band groups to allocate subnets of a new band group to the devices(31,32)(S13,S14). The devices(31,32) configure networks within the allocated band group(S15) as performing communication, and return to networks of an existing band group if the communication is terminated(S16).
