摘要： This application provides a communication method applied to an integrated access and backhaul IAB system. The method includes: A child node receives a first radio resource control RRC reconfiguration message from an access network device via a parent node, where the first RRC reconfiguration message includes a random access-free indication. The child node starts a timer. The child node sends a first RRC reconfiguration complete message to the access network device via the parent node. The child node receives first indication information from the parent node, where the first indication information indicates to stop the timer. The child node stops the timer.

摘要： 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.

摘要： This application provides a communication method and apparatus, and relates to the field of communication technologies. The method may include: A network device performs integrity protection on system information by using a first private key, and sends the system information, where the system information includes a first public key corresponding to the first private key and/or an index of the first public key. Correspondingly, a terminal device receives the system information from the network device, and if determining that the first public key is valid, the terminal device verifies integrity of the system information by using the first public key. According to this method, on one hand, the terminal device can effectively identify validity of the system information. On the other hand, because the system information includes the first public key and/or the index of the first public key, flexible update of an asymmetric key can be implemented.

摘要： Embodiments of this application provide a mode switching method, a data flow splitting method, and an apparatus. The mode switching method includes: generating, by a first device, first indication information, where there are connections between a PDCP unit in the first device and at least two RLC units in a second device; and sending, by the first device, the first indication information to the second device, where the first indication information is used to indicate the second device to stop transmission between a first RLC unit in the at least two RLC units and the PDCP unit in the first device. The second device stops transmission between the first RLC unit and the PDCP unit based on the first indication information, to cancel duplication transmission of the second device.
