Patent ID: 8666419

Claim:
A method for performing a handover of a communication session from a non 3GPP access network to a 3GPP access network, the method comprising: establishing, through the non 3GPP access network, the communication session between (i) a user equipment, and (ii) an Evolved Packet Core; performing a handover of the communication session from the non 3GPP access network to the 3GPP access network, wherein performing the handover includes prior to the handover of the communication session from the non 3GPP access network to the 3GPP access network, providing, to the user equipment, identification of a packet data network gateway, and during the handover of the communication session, providing the identification of the packet data network gateway from the user equipment to the 3GPP access network to maintain continuity of the communication session between the user equipment and the Evolved Packet Core.
