Abstract: A method and an apparatus may be applied to a network slice architecture. The method includes: a terminal sends, to an access network device, first data and indication information used to indicate a first slice corresponding to the first data, and the access network device may determine, based on a mapping relationship between a slice and a tunnel, a first tunnel corresponding to the first slice. In other words, different slices may correspond to different tunnels, that is, data corresponding to different slices may be transmitted through different tunnels. In this way, the access network device can reduce congestion caused because data is simultaneously transmitted through a same tunnel for communication, thereby helping improve communication efficiency.

Abstract: This application provides a communication method and a communications apparatus. The communication method may includes receiving, by a first forwarding device in a mobile network, a first data packet, where the first data packet carries first data from a first terminal device, the first data packet includes a target field, information carried in the target field is used to determine target information. The target information may include information about at least one second terminal device or information about a first area, the second terminal device is a terminal device to which the first data needs to be sent, and the first area is an area to which the first data needs to be broadcast. The communications method may also include sending, by the first forwarding device, a second data packet based on the target information, where the second data packet carries the first data, so that the first forwarding device does not need to send the first data to a device such as a server configured to implement a routing and addressing function, thereby reducing a transmission latency.
