摘要： 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. In this way, a transmission rate and reliability of sensory data transmission can be improved.

摘要： This application provides a UE sensing method and a communication apparatus. An SF network element, an NEF network element, an AMF network element, an SMF network element, a RAN network element, or the like may perform sensing detection on UE for a sensing requester or the UE, and provide a corresponding sensing service for the sensing requester or the UE. In some implementations, the sensing requester may be the UE, or may be an application function AF. Usually, the AF may directly request the sensing service from a communication system (for example, a 5GS), and the UE may request the sensing service from a communication system (for example, a 5GS), may perform sensing by directly requesting a sensing resource from the RAN network element based on a sensing requirement of the UE, or may perform sensing in collaboration with the RAN network element, and obtain sensing data, so that the sensing data can be quickly and efficiently obtained. In addition, in some implementations, not only sensing on the UE can be implemented, but also security and privacy on a UE side can be protected.

摘要： This application discloses a communications method and apparatus, and relates to the communications field, to resolve a problem that a terminal device can still receive downlink LADN data when moving out of an LADN SA. The method in this application includes: receiving, by a RAN node, a first message from an AMF node, where the first message includes specified area related information of a terminal device, and the specified area related information is used to indicate a specified area of the terminal device; and when the RAN node determines, based on the specified area related information and first location information of the terminal device, that the terminal device moves out of the specified area, sending, by the RAN node, the first location information or first indication information to the AMF node or a session management function SMF node, where the first indication information is used to indicate that the terminal device already moves out of the specified area. This application is applicable to a 5G communications procedure.

摘要： Embodiments of this application provide a spectrum resource sharing method, a device, and a system, to improve user experience of a specific user (for example, a high-value user) or a specific service (for example, a high-value service). The method includes: A mobility management entity determines that a first terminal device is allowed to occupy a spectrum resource of a first network, where the first terminal device subscribes to a second network. The mobility management entity sends first indication information to an access network device, where the first indication information indicates that the first terminal device is allowed to occupy the spectrum resource of the first network. After receiving the first indication information, the access network device occupies the spectrum resource of the first network for the first terminal device based on the first indication information.

摘要： Embodiments of this application provide a communication method and apparatus, to transmit multicast data by using a same multicast user plane network element. The method may include: A first session management network element receives a first request used to request to use a first PDU session to transmit multicast data, and obtains identification information of a multicast user plane network element based on identification information of the multicast data. Alternatively, a mobility management network element receives a PDU session establishment request for establishing a multicast PDU session, and sends, based on the PDU session establishment request, the PDU session establishment request to a session management network element that manages a multicast user plane network element. Alternatively, a first session management network element obtains forwarding configuration information or QoS context information of multicast data, and sends, to a second session management network element, first path information used to establish a transmission path for multicast data transmission between a multicast user plane network element and a unicast user plane network element, or second path information used to establish a transmission path between the multicast user plane network element and an access network device.

摘要： The present invention discloses a broadcast method, an apparatus, and a system. According to a solution provided in embodiments of the present invention, 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. According to the solution, an appropriate terminal can be selected in the transmission range of the data to broadcast the data, and information redundancy, channel contention, and collision interference that are caused by broadcast flooding can be reduced while a broadcast coverage requirement is satisfied. The solution may be applied to a multi-hop broadcast scenario in vehicle to X.
