The method includes that a user terminal device broadcasts its own device information and service capability information, and searches for information about a surrounding service network, information about a device not joining the service network and service capability information about the device; if it is discovered that a service network, which has a service capability needed by the user terminal device to accomplish a service, exists in the surrounding area, the user terminal device is configured to join the service network, and interact with a central node of the service network to accomplish the service; and if the service network is not discovered, the user terminal device selects a central node from devices which do not join a service network and have a service capability needed by the user terminal device to accomplish the service, is configured to generate a service network according to the selected central node, and interact with the selected central node to accomplish the service. A ubiquitous service can be provided through discovery, acquisition and networking of surrounding available service resources."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and service discovery method, and device middleware","description":"A device and service discovery method and a piece of device middleware are provided.
