Abstract
This application provides a communication method and apparatus. The method includes: After receiving a first packet from a first device, a first user plane network element determines a user plane LAN identifier corresponding to the first packet, where the user plane LAN identifier is an identifier that is in a user plane and that is of a LAN group to which the terminal belongs, and one user plane LAN identifier corresponds to one LAN group. That is, a function of the user plane LAN identifier is to isolate user plane packets of different LAN groups. Then, the first user plane network element sends the first packet to a second device based on the user plane LAN identifier and a destination address included in the first packet, so that the first packet sent by one terminal in the LAN group is sent to another terminal in the LAN group.
