Abstract:
1. A method of further establishing an extended IP flow to a user equipment (UE), the method comprising: establishing, at a packet data network gateway (PDN-GW) included in an evolved packet core (EPC), an initial IP flow with the UE through a first type access network; and further establishing, at the PDN-GW, the extended IP flow with the UE through a second type access network different from the first type access network, while maintaining, at the PDN-GW, the initial IP flow with the UE through the first type access network, wherein a binding update is received at the PDN-GW, wherein a binding acknowledgement is transmitted by the PDN-GW in response to the binding update if a single IP address is allocated to identify both the initial IP flow and the extended IP flow, and wherein the single IP address is included in the binding acknowledgement.
