Abstract: Embodiments of this application disclose a communication method and a related communication apparatus. In a dual connectivity scenario, user equipment (UE) establishes a dual connection to a master radio access network node (MN) and a secondary radio access network node (SN). When the MN requests the SN to provide a multicast broadcast service (MBS) for the UE of the MN, the MN sends a first request to the SN, where the first request includes a first identifier corresponding to the MBS. After receiving the first request, the SN sends a first response to the MN, where the first response indicates that the SN agrees to provide the MBS service for the UE. In this way, MBS service data is sent to the UE through the SN in the dual connectivity scenario.

Abstract: The present disclosure relates to communication methods and apparatus. In one example method, a first message from a relay terminal is received by a first terminal. The first message includes first indication information, an application layer identifier of a second terminal, and a first address of the second terminal. The first indication information can indicate a first unicast link between the first terminal and the relay terminal. The first terminal updates first information of the first unicast link based on the first message to obtain updated second information of the first unicast link. The second information includes the application layer identifier of the second terminal and the first address.

Abstract: The present disclosure relates to device-to-device (D2D) communication methods, apparatus, and systems. In one example method, a first terminal establishes a sidelink between the first terminal and a second terminal, where the sidelink corresponds to a sidelink slice. The first terminal communicates with the second terminal on the sidelink by using a physical transmission resource corresponding to the sidelink slice.

Abstract: A target tracking apparatus includes an image sensor, a controller, an image signal processor, and an event processor. A processing capability of the image signal processor is different from a processing capability of the event processor. The image sensor is configured to: capture a first raw (RAW) image, and send the first raw image to the controller. The controller is configured to: determine a motion distance, in two adjacent frames of raw images, of a target object in the first raw image, where the first raw image is a next frame of image of the two adjacent frames of raw images; determine a target processor from the image signal processor and the event processor based on the motion distance, where a processing capability of the target processor matches the motion distance; and perform target tracking on the target object based on the first raw image by using the target processor.

Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a session management function (SMF) receives a first message including a multicast address from a terminal, sends a second message to a network registration function (NRF), where the second message is used to query for an SMF that establishes a multicast session for a multicast service corresponding to the multicast address, receives, from the NRF, a third message indicating that the SMF that establishes the multicast session for the multicast service corresponding to the multicast address is not found, and sends, to the terminal, a fourth message indicating that the terminal is rejected to join the multicast session corresponding to the multicast address.

Abstract: This application provides a communication method and apparatus, to improve data transmission efficiency. The communication method and apparatus may be used in systems such as a 5G system and a V2X system. The method includes: After receiving, through a first unicast session, a request message for adding a first terminal to a multicast group, a first session management network element sends second information based on first information. The second information is for requesting a first user plane network element to send multicast data not through the first unicast session or not to send first signaling to a data network. The first signaling is for establishing a second tunnel used by the data network to send the multicast data to the first user plane network element, and the first user plane network element is a user plane network element corresponding to the first unicast session.
