Abstract: This application discloses a data compression method and apparatus. The method includes: obtaining m data blocks in a data area of a readable and writable file system; compressing the m data blocks by using a preset compression algorithm, to sequentially obtain n compressed data blocks, where first capacities of the compressed data blocks are the same, and the first capacity represents a quantity of bytes of compressed data that can be included in the compressed data block; and establishing a first index of each of j data blocks corresponding to an ith compressed data block in the n compressed data blocks, and recording a mapping relationship between first indexes and the j data blocks. The first index is used to identify a storage location, in a storage medium, of each data block included in the j data blocks, and attribute information included in each of the j data blocks.

Abstract: The present disclosure relates to the communications field, and disclose a wireless connection switching method and a terminal. A specific solution is as follows: A first terminal establishes a first wireless connection to a second terminal. When the first terminal needs to establish a second wireless connection to the second terminal, the first terminal negotiates, with the second terminal by using the first wireless connection, information required for establishing the second wireless connection. Subsequently, the first terminal can establish the second wireless connection to the second terminal based on the negotiated information required for establishing the second wireless connection.

Abstract: Embodiments of the present invention provide a communication establishment method. The method includes: receiving, by a first terminal, a first broadcast message of a first wireless communications mode sent by a second terminal, where the first broadcast message carries a second wireless communications mode supported by the second terminal and a status and/or supported protocol information of the second wireless communications mode; and determining, by the first terminal based on the second wireless communications mode supported by the second terminal and the status and/or the supported protocol information of the second wireless communications mode, whether to connect to the second terminal. According to the foregoing method provided in the embodiments of the present invention, in a first wireless communication phase, a status and/or a supported protocol of a second wireless communications mode can be obtained, so that the second wireless communications mode is learned of in advance and terminals are filtered, thereby improving efficiency of selecting a wireless communications mode and establishing a communication connection.
