摘要
A system and method provides seamless switchover of a user device (UE) between a mobile data network and a wireless network while providing policy and charging control (PCC) of the data session in the mobile data network. A mobile core network component is made ASF aware to process user data traffic related to an auto switching function (ASF) server from a UE client located on the UE using a special access point name (APN). The mobile core network component then uses a dedicated deep packet inspection (ASF DPI) for all data transfers to the special APN. The core network component is then able to process the UE data traffic seamlessly as the traffic is toggled between the ASF tunnel the WiFi tunnel. By monitoring the data traffic on the ASF tunnel, the core component (GGSN/PGW) is able to provide PCC for the data session.
