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.

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.

Abstract: Embodiments of this application provide a data transmission method and a host machine, so that when a host machine cannot directly connect to the Internet, a virtual terminal can still connect to a mobile network. This extends an application scope of the virtual terminal. The host machine obtains a first network address of a physical terminal, where the physical terminal has started to establish a connection or has established a connection to the mobile network; and the host machine sets a second network address of the virtual terminal to the first network address, so that the virtual terminal sends data to the mobile network by using the first network address and/or receives, by using the first network address, data sent by the mobile network. The virtual terminal runs on the host machine.
