Providing for select Internet Protocol traffic offload (SIPTO) in a mobile communication environment is described herein. By way of example, SIPTO traffic can be facilitated via local packet gateways (P-GWs) that provide an interface to the Internet or a like data network, in addition to a centralized gateway GPRS support node (GGSN). Eligibility for SIPTO can be on a user equipment (UE) by UE basis; for instance, relying on stored subscription or account information to determine SIPTO eligibility. In particular aspects, eligibility for SIPTO can also be based on a packet network by packet network basis, or a combination of the foregoing. This enables flexibility in determining whether SIPTO can be established for a given UE in a given location, and can be based for instance on UE capability, subscription status information, data network capability, tariff rates, and so on, as well as different legal requirements of government jurisdictions. |
