Abstract: Example data security processing methods and apparatus are described. One example method includes setting up a first PDU session. A first base station derives a first user plane key based on a received base key and performs security processing on user plane data in the first PDU session by using the first user plane key and a security algorithm. A second PDU session is set up. The first base station derives a second user plane key based on the base key and performs security processing on user plane data in the second PDU session by using the second user plane key and the security algorithm. The user plane key includes a user plane encryption key and/or a user plane integrity protection key.

Abstract: The present disclosure relates to connection establishment methods and apparatus. In one example method, a central unit (CU) function entity receives a first connection establishment request of a master device, where the first connection establishment request includes at least first identification information of a terminal, identification information of a first data radio bearer (DRB), identification information of a target cell, and interface information of the master device. The CU function entity sends a second connection establishment request to a distributed unit (DU) function entity to request the DU function entity to establish a connection to the master device, where the second connection establishment request includes at least second identification information of the terminal, the identification information of the first DRB, and the interface information of the master device.

Abstract: The present invention provides a method and a device for interference coordination. The method comprises: determining mutually interfering wave beams between a cell of a first base station and a cell of a second base station based on first interference information and second interference information; coordinating time-frequency resources, time domain resources or frequency domain resources occupied when the mutually interfering wave beams between the cell of the first base station and the cell of the second base station are sent, so as to reduce interference. By coordinating, wave beams of the cells of the base stations are sent in a staggered manner in terms of the time-frequency resources, the time domain resources or the frequency domain resources.

Abstract: A method for multicast communication, a first network device, and a second network device. The method includes: a first network device sends first information to a second network device, where the first information indicates an association relationship between multicast service information and a first terminal device; the first network device receives second information from the second network device; the first network device generates a configuration message based on the second information, where the configuration message indicates an association relationship between the multicast service information and a first logical channel, and the first logical channel is a logical channel of the first terminal device; and the first network device sends the configuration message to the first terminal device.

Abstract: This application discloses a handover method and apparatus. During handover, a source RAN node includes, in a handover message, an indication indicating whether a PDU session supports network slice re-mapping and/or an indication indicating whether the PDU session supports network slice fallback. A target RAN node performs admission control based on the indication, and notifies the source RAN node of an identifier of a network slice to which the PDU session is re-mapped or an indication indicating whether the PDU session falls back to a default network slice. The source RAN node forwards the notification to a terminal device. This reduces signaling overheads caused during handover interaction.

Abstract: The present disclosure relates to radio resource control (RRC) reestablishment methods and apparatuses. In one example method, a terminal device selects a target cell, where the target cell supports an expected network slice. The terminal device sends an RRC reestablishment request message by using the target cell. The expected network slice may include a network slice that the terminal device expects to access, or a network slice corresponding to a PDU session established by the terminal device by using a last serving access network device of the terminal device. The terminal device may select the target cell within a preset time period. For example, the terminal device starts a first timer when the terminal device starts selecting the target cell, and selects the target cell during running of the first timer. The first timer may be specific to one or more network slices or all network slices.
