Abstract
A computer device may include a memory configured to store instructions and a processor configured to execute the instructions to receive a handover request from a user equipment (UE) device via an evolved Packet Data Gateway (ePDG), wherein the handover request includes a request for a dual Packet Data Network (PDN) context and designate the UE device as having dual PDN context, based on the received handover request. The processor may be further configured to identify an Internet Protocol (IP) address for a Long Term Evolution (LTE) bearer associated with the UE device; create a PDN session to the ePDG using the IP address, based on the UE device having the dual PDN context; and send a Protocol Configuration Options (PCO) message to the UE device via the ePDG, wherein the PCO message includes an indication of dual PDN context support; and select to maintain the LTE bearer.
