摘要： Embodiments of this application provide a data sending method, apparatus, and system, and relate to the communications field, so that an SN change in dual connectivity does not affect performance of a network in which an MN is located. The data sending method specifically includes: determining, by a source node device, whether direct data forwarding is supported between the source node device and a destination node device; and sending, by the source node device, a first message including a first indication to a first node device, where the first indication is used to indicate whether the direct data forwarding is supported between the source node device and the destination node device. This application is used for data sending.

摘要： The present application discloses a method and an apparatus. In the present application, a radio access network RAN server receives a measurement report from a terminal, determines a target inter-RAT cell of the terminal based on the measurement report, and configures a resource for the terminal in the target inter-RAT cell. The configured resource is a resource to be used by the terminal to access the target inter-RAT cell. The RAN server sends a handover command to the terminal. The handover command is used to instruct the terminal to hand over to the target inter-RAT cell, and the handover command carries an identifier of the target inter-RAT cell and information about the configured resource. In this way, when handover is performed between inter-RAT cells, handover can be implemented without across core networks, thereby reducing signaling exchange between a source core network and a target core network.

摘要： This application provides a relay communication method, a communication apparatus, and a communication system, to effectively improve efficiency of accessing a cell of a network device by a remote terminal. The method is applied to a communication system including a first terminal, a second terminal, and a third terminal, and the first terminal is a relay device used by the second terminal to access a network device. The method includes: The first terminal receives system information from the network device, and determines, based on the received system information, that the second terminal fails to camp on a first cell of the network device. The first terminal sends first indication information to the second terminal, where the first indication information indicates to break a sidelink between the first terminal and the second terminal, or the first indication information indicates that the second terminal fails to camp on the first cell.

摘要： This application provides a system information SI transmission method and apparatus. The method includes: The first terminal device receives a first request message sent by the one or more second terminal devices. The first request message is used to request to obtain M system information blocks SIBs or system information SI messages of a serving cell. The first terminal device determines N destination identifiers corresponding to the M SIBs or SI messages, where N is an integer greater than or equal to 1, and N≤M. The first terminal device sends, based on the N destination identifiers, the M SIBs or SI messages to the one or more second terminal devices in a broadcast or multicast manner. According to the method, the SI may be transmitted on an SL in the multicast or broadcast manner. This improves SI transmission efficiency and SI update efficiency.
