Abstract: Embodiments of the invention are directed to systems, methods and computer program products for routing traffic in a packet data network (PDN). A method includes determining whether the mobile device has an active long-lived data traffic session over an original PDN connection between the mobile device and a first PDN gateway (P-GW); if the mobile device has an active long-lived data traffic session, then routing any new long-lived data traffic session over the original PDN connection; and if the mobile device does not have an active long-lived data traffic session, then routing any new long-lived data traffic session over a location-based PDN connection established based at least in part on a current location of the mobile device. In other words, the mobile device initiates and maintains all long-lived data sessions (for which service continuity is essential) to only one PDN connection.
