  • Patent number: 11770726
    Abstract: A communication method includes obtaining, by an Internet of things platform, historical load of a serving cell of a terminal, determining, by the Internet of things platform, a data reporting time of the terminal based on the historical load of the serving cell, and sending, by the Internet of things platform to the terminal, a time at which the terminal reports data. In this embodiment, the data reporting time of the terminal is determined based on the historical load of the serving cell and a time range in which the terminal can report data.

  • Patent number: 11528235
    Abstract: An Internet of Things resource subscription method includes a parameter that is added to a subscription request message such that the device identifies, in a multiple-resource subscription scenario, parameters that need to be reported and parameters only used as subscription determining conditions. The Internet of Things resource subscription method can further enable a server to flexibly set, using a logical expression, a subscription condition in a subscription request.

  • Patent number: 11523252
    Abstract: A positioning method includes separately sending, by a terminal, a request for obtaining assistance data to a serving base station and a neighboring cell base station; separately receiving, by the terminal, assistance data from the serving base station and the neighboring cell base station; identifying, by the terminal based on the assistance data, reference signals received from the serving base station and the neighboring cell base station; calculating, by the terminal, a time difference of arrival based on times at which the reference signals arrive at the terminal; and sending, by the terminal, the time difference to a server using an application layer protocol, to enable the server to calculate location information of the terminal.

  • Patent number: 10637794
    Abstract: A network resource subscription system is provided. In the system, a subscription apparatus and a publishing apparatus respectively send a resource subscription request and a resource publishing request to a control apparatus through a forwarding apparatus, to establish a network resource tree. Then, the control apparatus can use a relatively exact or fuzzy matching manner to make the subscription apparatus subscribe to a resource of the publishing apparatus, and make the subscription apparatus and the publishing apparatus perform peer to peer (P2P) communication, thereby taking both transmission efficiency and subscription efficiency into account.
