A wireless communication method, comprising: receiving (103; 205), by a first user plane function, UPF, entity, a first message from a session management function, SMF, entity, wherein the first message comprises a multicast address of a group comprising a first terminal and at least one second terminal and session information of the at least one second terminal, and the first message is used by the first UPF entity to send received first service data to each of the at least one second terminal, the first service data being data that is from the first terminal and whose destination address is the multicast address of the group, and wherein the session information of the at least one second terminal includes information about a tunnel between a radio access network, RAN, of each of the at least one second terminal and the first UPF entity or information about a tunnel between a second UPF entity in which each of the at least one second terminal is located and the first UPF entity, and/or address information of each of the at least one second terminal, wherein the address information of each of the at least one second terminal comprises an Internet Protocol, IP, address of each of the at least one second terminal; and duplicating (104; 207), by the first UPF entity, received first service data from the first terminal to obtain N copies of first service data, and sending the duplicated first service data to each of the at least one second terminal based on the multicast address of the group and the session information of the at least one second terminal, wherein N is a total quantity of the at least one second terminal. receiving (103; 205), by a first user plane function, UPF, entity, a first message from a session management function, SMF, entity, wherein the first message comprises a multicast address of a group comprising a first terminal and at least one second terminal and session information of the at least one second terminal, and the first message is used by the first UPF entity to send received first service data to each of the at least one second terminal, the first service data being data that is from the first terminal and whose destination address is the multicast address of the group, and wherein the session information of the at least one second terminal includes information about a tunnel between a radio access network, RAN, of each of the at least one second terminal and the first UPF entity or information about a tunnel between a second UPF entity in which each of the at least one second terminal is located and the first UPF entity, and/or address information of each of the at least one second terminal, wherein the address information of each of the at least one second terminal comprises an Internet Protocol, IP, address of each of the at least one second terminal; and duplicating (104; 207), by the first UPF entity, received first service data from the first terminal to obtain N copies of first service data, and sending the duplicated first service data to each of the at least one second terminal based on the multicast address of the group and the session information of the at least one second terminal, wherein N is a total quantity of the at least one second terminal. <EOS>
