1. A wireless communication method implemented by a first user plane function entity and comprising:
receiving, from a session management function entity, a multicast address of a group and session information of second terminals, wherein the group comprises a first terminal and the second terminals, and wherein the session information comprises information about a tunnel between second user plane function entities in which the second terminals are located and the first user plane function entity;
receiving, from the first terminal in the group, first service data, wherein a destination address of the first service data is the multicast address;
duplicating, when the destination address of the first service data matches the multicast address of the group, the first service data to obtain copies of the first service data; and
sending, to each terminal of the group except the first terminal and based on the multicast address and the session information, each of the copies of the first service data.
