Claim 15:
16. The method of claim 15, wherein:
the external MPTP proxy node (a) receives, from the UPF node via the UPF-proxy interface, (i) 3GPP uplink data transmitted by the UE node via a 3GPP radio access network (RAN) and (ii) non-3GPP uplink data transmitted by the UE node via a non-3GPP access network, (b) combines the 3GPP and non-3GPP uplink data to form network uplink data, and (c) provides the network uplink data to a data network; and
the external MPTP proxy node (a) receives network downlink data either (i) directly, from the data network via a network-proxy interface, or (ii) indirectly, from the data network to the UPF node via a network-UPF interface and then from the UPF node to the external MPTP proxy node via the UPF-proxy interface, (b) divides the network downlink data into (i) 3GPP downlink data and (ii) non-3GPP downlink data, and (c) provides the 3GPP and non-3GPP downlink data to the UPF node via the UPF-proxy interface for transmission to the UE node via the 3GPP RAN and the non-3GPP access network, respectively.
