Claim:
1. A method comprising: communicating, by an enhanced packet data gateway (ePDG) with a gateway of a long-term evolution (LTE) network, wherein upon attachment to the gateway by a mobile device through a wireless cellular access technology, the gateway is to provide an Internet Protocol (IP) address to the mobile device, the mobile device to use the IP address as a source IP address to communicate using the wireless cellular access technology during a first packet data network connection for an access point name (APN); facilitating, by the ePDG, attachment by the mobile device to the gateway through a wireless non-cellular access technology, wherein during attachment the gateway is to allocate the same IP address to the mobile device, the mobile device to use the IP address as its source IP address to communicate using the wireless non-cellular access technology during a second packet data network connection for the APN; during attachment by the mobile device to the gateway through the wireless non-cellular access technology, receiving by the ePDG from the mobile device, a traffic selector via an Internet Key Exchange (IKE) configuration request, the traffic selector based on traffic to be offloaded to the wireless non-cellular access technology; and sending, by the ePDG to the gateway of the LTE network, at least one flow descriptor from the traffic selector received from the mobile device for validation of the at least one flow descriptor.
