Abstract: A clock synchronization method, including: obtaining (S201), by a slave clock apparatus, a first time point at which a master clock apparatus sends first information, a second time point at which the slave clock apparatus receives the first information from the master clock apparatus, a third time point at which the slave clock apparatus sends first feedback information, and a fourth time point at which the master clock apparatus receives the first feedback information from the slave clock apparatus; then obtaining (S202) a first clock count offset based on the first time point, the second time point, the third time point, and the fourth time point; then obtaining (S206) a first clock frequency offset based on the first clock count offset; and finally adjusting (S207) a clock count step of the slave clock apparatus based on the first clock frequency offset.

Abstract: A standby control method includes sending first notification information to a relay device through a first communication link by a terminal before entering a standby mode. The relay device serves as a proxy for the terminal based on the first notification information, and the relay device sends a first keep-alive packet to a cloud server to inform the cloud server that the terminal is online. The terminal then disables the first communication link and a main CPU. The relay device sends a second keep-alive packet to the terminal through a second communication link, and the terminal sends acknowledgement information of the second keep-alive packet to the relay device through the second communication link to inform the relay device that the terminal is online, where a communication rate of the second communication link is lower than a communication rate of the first communication link.

Abstract: Embodiments of this application disclose a network configuration method and apparatus for an intelligent device. A terminal broadcasts a first discovery packet to the intelligent device. After the intelligent device receives the first discovery packet, the intelligent device broadcasts a first response packet in a short-distance transmission mode. In the short-distance transmission mode, a sending distance of the first response packet does not exceed a first safe distance. The terminal obtains information related to the intelligent device based on the first response packet, performs validity authentication on the intelligent device, and broadcasts an SSID and a password that are of a router and that are encrypted to the intelligent device after the terminal verifies that the intelligent device is valid. The intelligent device accesses the router based on the SSID and the password that are of the router and that are obtained through decryption.

Abstract: Computer systems, service processing methods, and chips are provided in this disclosure. In one implementation, a computer system comprises an interrupt status register, a permission management register, a processor, a target storage space, and a memory storing programming instructions for execution by the processor to: set a flag corresponding to the first interrupt in the interrupt status register to a first interrupt flag and a flag corresponding to the first interrupt in the permission management register to a first call flag, wherein the first interrupt flag and the first call flag indicate whether access to the target storage space is allowed, determine whether to allow the processor to access the target storage space, and obtain first information in the target storage space in a TEE mode if determining that the processor is allowed to access the target storage space; and execute the target service based on the first information.

Abstract: This application discloses a method for implementing a Wi-Fi peer-to-peer service and a related device. The method may be applied to the field of Wi-Fi communication. The method includes: A first device sends a first action frame to a second device through a first channel, where the first action frame carries a channel switching parameter. Then, both the first device and the second device switch to a same channel indicated by the channel switching parameter to perform Wi-Fi peer-to-peer service communication.
