Abstract: Embodiments of the present disclosure disclose a method, an apparatus, and a system for data transmission. The method includes: broadcasting, by a relay device, a first message, where the first message is used to indicate that the relay device supports data forwarding; receiving, by the relay device, a second message from a remote device, where the second message includes data of the remote device; and sending, by the relay device, the data to a core network device based on the second message. In the present method, after receiving the first message broadcast by the relay device, the remote device directly sends the data of the remote device to the relay device without establishing a connection dedicated for transmitting the data of the remote device between the remote device and the relay device, thereby reducing signaling and reducing power consumption of the remote device.

Abstract: A communications method, apparatus, and system are disclosed. The method includes: generating, by an access device, a temporary identity sequence for a terminal, and sending a first message carrying the temporary identity sequence to the terminal; receiving, by the terminal, the first message sent by the access device, selecting one temporary identity from the temporary identity sequence, and generating, based on an area key of the terminal, the selected temporary identity, and a PDCP data SDU of the terminal, a PDCP data PDU of the terminal, which is used when a V2X message of the terminal is sent, where the area key is an area key of an area corresponding to location information of the terminal. This can implement security requirements of anonymity, non-traceability, and non-repudiation of V2X communication, and reduce security overheads and a processing delay of the V2X communication.

Abstract: This application provides a sensory data transmission method. The method includes: A first sensing network element sends first address information of the first sensing network element to a second sensing network element. The first address information is used to establish a first data channel for transmitting sensory data between the first sensing network element and the second sensing network element. The first sensing network element sends a first request message to the second sensing network element. The first request message is used to request the second sensing network element to perform a first sensing operation. The first sensing network element receives first data information that is sent by the second sensing network element through the first data channel. The first data information is generated by the second sensing network element by performing the first sensing operation based on the first request message.

Abstract: A communication method, applied to a scenario wherein a terminal device is moving from a source access network device to a target access network device and performing a multicast service, includes obtaining, by the target access network device, reference information of the multicast service, The reference information includes area information. The area information corresponds to a sub-service area of the multicast service. The method also includes sending, by the target access network device, information about a forwarding path based on the reference information. The forwarding path is used for the target access network device receiving data of the multicast service.

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.
