    Abstract: Embodiments of this application provide a message identification method and apparatus. The method includes: receiving, by user equipment UE, a paging message sent by an access network device; determining, by the UE, a core network entity to which the paging message belongs in a plurality of core network entities serving the UE; and establishing, by the UE, a data connection to the core network entity to which the paging message belongs. According to the message identification method and apparatus provided in the embodiments of this application, the UE can connect to different core network entities.

    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 method of distributing a security key context, where the method includes receiving, by a mobility management entity, a first indication from a primary base station, where the first indication is used for requesting a path switch from the mobility management entity and indicating that the path switch is triggered by carrier aggregation between base stations, processing the path switch according to the first indication, and keeping, according to the first indication, the security key context for the path switch unchanged, and sending a second indication to the primary base station, to indicate the primary base station to keep the security key context unchanged, or sending a third indication to the primary base station, to indicate the primary base station to acquire a quantity of times of reversal of a next hop chaining counter in the security key context.
