  • Patent number: 11711670
    Abstract: A method for providing a service based on a user scenario, a terminal device, and a system. The terminal device perceives the user scenario with low power consumption, and a cloud-side service open platform determines a corresponding scenario package based on the user scenario, where the scenario package includes a plurality of pre-orchestrated services for the user scenario. The service open platform pushes data related to the determined scenario package to the terminal device, and the terminal device displays entry interfaces of the plurality of services, and provides a corresponding service based on an operation performed by a user on the entry interface.
