Abstract: This application provides a multipath transmission method and a communication apparatus. In this solution, data of a remote terminal is transmitted through two paths, to improve data transmission reliability of the remote terminal. The solution includes: A user plane function node receives second information from a session management function node; and the user plane function node replicates, based on the second information to the second communication path, data that is of the remote terminal and that is transmitted through a first communication path. The first communication path is a first session of the remote terminal, and the second communication path includes a second session of a relay terminal corresponding to the remote terminal and a sidelink between the relay terminal and the remote terminal.

Abstract: The present disclosure describes a broadcast method, an apparatus, and a system. In one example, a broadcast decision apparatus obtains broadcast decision information of a plurality of terminals, where the broadcast decision information includes at least location information of the terminals. The broadcast decision apparatus selects some terminals from the plurality of terminals as relay terminals based on the broadcast decision information and a transmission range of data, and sends configuration information to the relay terminals to indicate the relay terminals to broadcast the data.

Abstract: Example communication methods apparatus are described. One example method includes receiving air interface link signal information of neighboring network devices by a source network device from a terminal device. The source network device determines a target network device based on sidelink information of the terminal device and the air interface link signal information of the neighboring network devices. Then, the source network device may send a handover request to the target network device, so that the terminal device can be handed over from the source network device to the target network device. Therefore, the target network device determined by the source network device can better meet an air interface link communication requirement and a sidelink communication requirement of the terminal device.

Abstract: A communication method and device are provided. A terminal device receives a paging message carrying first service information of a first service from an AMF network element, where the paging message corresponds to a first USIM in at least two USIMs of the terminal device; and sends a response message of the paging message to the AMF network element based on the first service information and service information of a second service, where the second service is a current service of a second USIM of the terminal device, and the second USIM is in connected state. In embodiments of the present invention, responding to the paging message is determined based on service information of a service instead of blindly responding to the paging message, to avoid suspending the service of the USIM currently in the connected state on the terminal device once the paging message is received.
