    Abstract: Embodiments disclose a cell status changing method. The method includes receiving, by user equipment, a first indication sent by a master base station, where the first indication is used to indicate a status change of a first cell of the master base station or a status change of a second cell of a secondary base station; and performing activation on the first cell or the second cell according to the first indication, or performing deactivation on the first cell or the second cell according to the first indication. In embodiments, both the master base station and the secondary base station serve the UE and undergo carrier aggregation, and the UE may obtain, by using the received first indication sent by the master base station, an active state or an inactive state of a serving cell that belongs to a base station that serves the UE.

    Abstract: This application provides method and apparatus for RRC state control. An access network device obtains RRC connected inactive state indication information of UE. When the UE leaves an RRC connected state, the access network device determines, based on the RRC connected inactive state indication information, that the UE enters an RRC connected inactive state or an RRC idle state, so that the access network device can control, based on a state of the UE, the UE to enter an appropriate RRC state, thereby reducing signaling overheads and improving system performance.

    Abstract: A cell access method includes determining, by a terminal in communication with a first cell, to communicate with a second cell, establishing a wireless connection by which the terminal communicates with the second cell in response to the determining to communicate with the second cell, accessing the second cell on the wireless connection by the terminal, and receiving, by the terminal, a reconfiguration message sent by a first base station of the first cell. The reconfiguration message is sent by the first base station to the terminal. The method further includes reconfiguring the wireless connection according to the reconfiguration message, and communicating with the second cell on the reconfigured wireless connection.
