A device and service discovery method and device

Abstract

The invention discloses a device and service discovery method and device middleware. The method includes: a user terminal device broadcasts its own device information and service capability information, and searches for surrounding service network information, device information and devices that have not joined the service network service capability information; if there is a service network in the surrounding area where the user terminal device has the service capability required to complete the business, the user terminal device is configured to join the service network and interact with the central node of the service network to complete the service; if there is no search To the service network, the user terminal device selects a central node from the equipment that has not joined the service network and has the service capability required to complete the business, and generates a service network according to the configuration of the selected central node, and interacts with the selected central node Get business done. The present invention can complete the provision of ubiquitous services through the discovery, acquisition and networking of available service resources in the surrounding area.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for discovering equipment and services. Background technique [0002] With the development of information technology, more and more smart devices will emerge in people's living and working environments. In order to make full use of various devices in the user's surrounding environment and provide users with effective, efficient, and high-quality services, it has become a demand for multiple devices to work together to provide services. The premise of multi-device collaboration is that devices can independently discover and interconnect to form a network. [0003] The device discovery in the prior art often obtains peripheral device information through channel broadcast or multicast messages to form a network, and completes service transmission and presentation through user configuration based on the network; since the device discovery p...
