    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.

    摘要翻译： 系统和方法提供移动数据网络和无线网络之间的用户设备（UE）的无缝切换，同时在移动数据网络中提供数据会话的策略和计费控制（PCC）。 移动核心网络组件使ASF感知到使用专用接入点名称（APN）从位于UE处的UE客户端处理与自动切换功能（ASF）服务器相关的用户数据流量。 然后，移动核心网络组件使用专用深度分组检测（ASF DPI）将所有数据传输到特殊APN。 核心网络组件然后能够在ASF隧道的WiFi隧道之间切换流量，从而无缝地处理UE数据流量。 通过监视ASF隧道上的数据流量，核心组件（GGSN / PGW）能够为PCC提供数据会话。
