Abstract: 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.

Abstract: 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.

Abstract: Embodiments of this disclosure relate to a sidelink communication method, including: A first user equipment receives a first message from a second user equipment; the first user equipment determines, based on the first message, a first frequency used to communicate with the second user equipment, where the first user equipment supports at least the first frequency and a second frequency, and the second user equipment supports at least the first frequency; and the first user equipment sends a second message to the second user equipment at the first frequency, where the second message is associated with a unicast connection establishment process or a discovery process. Therefore, the unicast connection establishment process or the discovery process can be performed on a carrier supported by all terminal devices that perform communication, to ensure that the unicast connection establishment process or the discovery process can be correctly performed, improving sidelink communication quality.
