ROUTING OF LONG-LIVED TRAFFIC WHEN USING SIPTO

摘要

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.

主权项

1. A method for routing traffic in a packet data network (PDN), the method comprising:
determining, by a mobile device, whether the mobile device has an active data traffic session over an original PDN connection between the mobile device and a first PDN gateway (P-GW); if so, determining, by the mobile device, that the active data traffic session over the original PDN connection requires IP address preservation; and routing, by the mobile device, a new data traffic session requiring IP address preservation over the original PDN connection.
