Abstract
A wireless communication method includes receiving, by a first user plane function (UPF) entity, a first message sent by a session management function (SMF) entity, where the first message includes a multicast address of a group and session information of at least one second terminal, and duplicating, by the first UPF entity, received first service data to obtain N copies of first service data, and sending the duplicated first service data to each second terminal based on the multicast address and the session information of the at least one second terminal, where the first service data is data that is from a first terminal and whose destination address is the multicast address, and N is a total quantity of the at least one second terminal.
