Claim 5:
6. A network device, comprising:
a processor, a memory, a transceiver, and instructions stored in the memory that, when executed by the processor, cause the transceiver to:
receive a data packet which is transmitted from a first terminal device through a control plane or a user plane within a 3rd Generation Partnership Project (3GPP) network; and
send the data packet to a second terminal device through the control plane or the user plane within the 3GPP network,
wherein there are a second session connection between the first terminal device and a UPF of the first terminal device, and a third session connection between the second terminal device and the UPF of the second terminal device, the UPF of the first terminal device and the UPF of the second terminal device are a same fourth UPF, and the network device is the fourth UPF, the data packet carries address information of the third session connection and/or identification information of the second terminal device, and
the transceiver is further configured to send the data packet to the second terminal device through the user plane based on the address information of the third session connection and/or the identification information of the second terminal device.
