Abstract
A Packet Data Network Gateway (P-GW) to maintain session continuity for a UE in an LTE network comprises a communication transceiver and a processing system. The communication transceiver is configured to receive a first session setup message for the UE. The processing system is configured to process the first session setup message to determine if the UE qualifies for alternate P-GW access, and if the User Equipment qualifies for the alternate P-GW access, generate a second session setup message indicating a primary P-GW ID, a primary P-GW TEID, an alternate P-GW ID, and an alternate P-GW TEID. The communication transceiver is configured to transfer the second session setup message for delivery to a Service Gateway (S-GW) in the LTE network, wherein the S-GW automatically uses the alternate P-GW ID and the alternate P-GW TEID if performance of the primary P-GW ID and the primary P-GW TEID falls below a threshold.
