Abstract: A terminal device determines that local first system information is abnormal in the case of any of the following: a quantity of times of sending first signaling is greater than or equal to a first preset threshold within first preset duration; a time length in which a first service is unavailable is greater than or equal to a second preset threshold; a change trend of a tag value of a same system information block is abnormal; or a quantity of changes in a tag value of a same system information block is greater than or equal to a third preset threshold within second preset duration. The terminal device receives, from an access network device, second system information that is used to update the local first system information. Therefore, the terminal device can determine as soon as possible whether the terminal device is being attacked by a rogue base station.

Abstract: This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.

Abstract: This application provides a cell selection method and apparatus, to resolve abnormal wireless communication between a terminal device and a selected cell. The method includes: A terminal device may obtain a first offset of at least one first to-be-selected cell. The first offset is used to determine a cell selection parameter of the at least one first to-be-selected cell. The cell selection parameter includes a cell selection receive level value Srxlev and/or a cell selection receive quality value Squal. Next, the terminal device may determine, based on uplink capability as to whether the terminal device can perform uplink enhancement, the cell selection parameter of the at least one first to-be-selected cell by using the first offset. Then, the terminal device may determine a first cell from the at least one first to-be-selected cell based on the cell selection parameter.

Abstract: In an active-active system, if write lock permission is granted to a second storage array, a first storage array sends to-be-written data and a lock revocation request together to a lock server; the lock server sends a lock revocation request carrying the to-be-written data to the second storage array; after storing the to-be-written data, the second storage array sends a lock revocation success message to the lock server; the lock server gives the write lock permission to the first storage array; and the first storage array obtains the write lock permission and stores the to-be-written data.
