Abstract: This application provides example methods and example apparatuses for sending multicast data. One example method includes establishing, by a core network user plane network element, a plurality of data connections to a terminal. The core network user plane network element can then determine a first data connection, where the plurality of data connections include the first data connection. The core network user plane network element can then receive multicast data sent to the terminal. The core network user plane network element can then send the multicast data to an access network element through the first data connection.

Abstract: This application describes examples of a tag locating method and system, and a related apparatus. In one example, a first network element sends first indication information to a location management function network element, where both the first network element and the location management function network element are network elements in a core network. The location management function network element obtains, based on the first indication information, a result of locating a first tag, and determines location information of the first tag based on the result of locating the first tag. The first network element obtains the location information of the first tag from the location management function network element.

Abstract: This application discloses a security parameter obtaining method, an apparatus, and a system, to ensure security of a private network service. In this application, security parameters used to derive an air interface control plane key and an air interface user plane key are separately generated, the security parameter used to derive the air interface user plane key is derived by using a root key of a private network, and derivation is completed in the private network, to prevent the root key of the private network and a process of deriving the security parameter from being exposed in a public network. In this way, when the air interface user plane key is used to securely transmit service data, security of service data transmission over an air interface can be improved.

Abstract: Embodiments of this application provide a communication method and apparatus, and relate to the communication field. The method in embodiments of this application includes: A control network element determines to use a same transmission path as a second service data flow for a first service data flow. The control network element sends first indication information to a target network element, where the first indication information indicates to transmit the first service data flow through a same transmission path as the second service data flow. In this way, the first service data flow and the second service data flow can be synchronously transmitted, to resolve a problem of a large transmission delay difference or asynchronization resulting from selecting different transmission paths for the service data flows.

Abstract: Embodiments of this application provide a terminal management method and a core network device. The method includes: A first core network device receives a first message from a terminal. When determining, based on quantity information, to allow the terminal to access the network, the first core network device sends a second message to an operation requester to which the terminal belongs. The quantity information includes a quantity of terminals that the operation requester is allowed to use, the second message includes first identification information. In embodiments of this application, the first core network device determines to allow the terminal to access the network, so that a quantity of terminals accessing the network among terminals corresponding to the operation requester can be prevented from being greater than or equal to the quantity of terminals that the operation requester is allowed to use.
