Abstract

A method to realize IP flow mobility (IFOM) between 3GPP access and non-3GPP access over GTP based interfaces is proposed. A user equipment is connected to a PDN-GW via a 3GPP access network and a non-3GPP access network. The UE transmits an IFOM triggering message to the PDN-GW, which selects IP flows to be moved based on EPS bearer ID and IP flow description. The PDN-GW sends an Update Bearer Request to a WAG or ePDG, and updates its mapping table if the Update Bearer Request is successful. The UE also updates its mapping table upon receiving an IFOM acknowledgement from the WAG or ePDG. The PDN-GW initiates a 3GPP bearer modification procedure to move the selected IP flows.
