Abstract: A data sending method, a data receiving method, a data transmit end, and a data receive end are provided. The data sending method includes: obtaining a transmission path used for data transmission, where the transmission path currently uses a first physical link group to transmit data; switching, based on a preconfigured link switching policy and transmission information of the transmission path, a physical link used by the transmission path from the first physical link group to a second physical link group; sending a first link switching notification message to a data receive end, where the first link switching notification message includes information indicating that the physical link used by the transmission path is switched from the first physical link group to the second physical link group; and continuing transmitting the data through a transmission path that uses the second physical link group.

Abstract: A storage fragment management method and a terminal. The method may be applied to a file system of the terminal, and the file system includes at least one segment. The method includes: first determining, by the terminal, a source segment from the file system based on an aging degree of the segment and a valid block ratio of the segment; then determining, by the terminal from the file system based on an aging degree of the source segment, a target segment whose aging degree is consistent with the aging degree of the source segment; and finally migrating, by the terminal, data of a valid block in the source segment to an idle block in the target segment. This method is used to resolve a problem that power consumption is high when data migration is performed on a storage fragment in an existing log-structured file system.

Abstract: This application provides a garbage data scrubbing method and a device, and relates to the field of terminals, to resolve a problem that delivering a discard message in a file system transaction affects a user foreground operation. The method includes: obtaining an IO busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state (S301); and if the IO busy/idle status of the terminal at the current moment is the idle state, delivering a discard message to a storage device (S302), where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.

Abstract: A storage system, a file storage and reading method, and a terminal device are provided. A storage system including a UFS is used as an example. The storage system configures different medium forms of the UFS, for example, configures persistent storage space of the UFS including SLC and TLC medium forms, to implement hybrid medium multi-disk storage. Based on the storage system, a hot file related to an application running rate is preferentially selected and stored in an SLC storage area of the UFS, and files on a mapped multi-disk are mounted on a same directory of a file system, so that files can be migrated between the SLC storage area and a TLC storage area without user perception, to improve performance of the storage system.

Abstract: A garbage data scrubbing method includes obtaining an input/output (IO) busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state. When the IO busy/idle status of the terminal at the current moment is the idle state, a discard message is delivered to a storage device, where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and where the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.

Abstract: A first device obtains an advertising parameter used by a second device to send an advertising data packet, where the advertising parameter includes an advertising window and an advertising interval. The first device determines, based on the advertising window and the advertising interval by using a preset scanning model, a target scan parameter used by the first device, where the target scan parameter is a scan parameter used by the first device when power consumption of the first device is a preset threshold and a scan-to-discover time period satisfies a preset condition. The target scan parameter includes a target scan window and a target scan interval. The first device performs scanning based on the target scan window and the target scan interval.

Abstract: Example image display methods and apparatus are described. One example method includes generating a first image based on first user operation information. The first image is stored into a memory. When second user operation information is detected, the first image corresponding to the second user operation information is determined in the memory and based on the detected second user operation information. Both the first user operation information and the second user operation information are used for displaying the first image. The first image is displayed.
