Abstract: This application discloses example communications methods and apparatuses. One example method includes receiving a first request message from a terminal, where the first request message is used to request information used for PC5 interface-based communication of the terminal. A second request message can be sent to a policy and charging function network element based on the first request message, where the second request message is used to request the information used for the PC5 interface-based communication. A quality of service (QoS) rule used for the PC5 interface-based communication can then be received from the policy and charging function network element. The QoS rule can then be sent to the terminal based on the first request message, where the apparatus is a mobility management network element or located in a mobility management network element.

Abstract: Embodiments of the present disclosure relate to a data transmission method, user equipment, and a control plane node. User equipment (UE) determines a security attribute of a session of the UE; the UE sends a session establishment request message to a control plane node when the security attribute of the session of the UE does not meet a security requirement of an application. The session establishment request message is used to request to establish a session corresponding to the security requirement of the application. Embodiments of the disclosed method reduce an unnecessary signaling exchange caused by establishment of a new session in a data transmission process to facilitate meeting requirements of different services.

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.

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.
