Fecha de publicación: 12/07/2012 Fuente: Wipo "IOT" An Internet of things (IOT) network system and a data processing method are provided in the present invention, which belongs to the IOT network technology field. The network system mainly consists of an IOT processing center (201), a distributed IOT domain processing service subsystem (202), multi-mode IOT gateways (205) and IOT devices (206). The IOT processing center (201) provides services and a developing platform to the outside. The distributed IOT domain processing service subsystem (202) coordinates with the IOT processing center (201) to provide services to users. The multi-mode IOT gateways (205) provide protocol conversion and security services. The IOT devices (206) are used to receive and send IOT data or to execute commands. During the network data processing in the IOT network system, the network data is inter-domain processed or intra-domain processed according to different services. The present invention solves the problem of integrated accessing for isomerous networks, improves the sharing rate of IOT resources, enhances the security guarantee of IOT information, and can be used for IOT network design and construction.
