<p>A method for maintaining IP context during an inter RAT handover of a UE between an eHRPD network and an LTE network may include delaying a transfer of an Internet Protocol context for at least one active packet data network until an IP address for an attach (PDN) Packet Data Network has been assigned and in the case where the Internet Protocol address for the Attach Packet Data Network is not assigned, initiating a detach operation from the LTE network without the user equipment losing the Internet Protocol context of the at least one active Packet Data Network.</p> |
