一种进行IP流切换的方法和装置
摘要：
本发明公开了一种进行IP流切换的方法和装置，用于解决将部分IP流从经由EPC路由的通信路径切换到邻近通信路径的具体实现问题。本发明实施例的方法包括：第一终端根据ANDSF策略确定特定IP流对应的优选的传输路径为邻近通信路径，且确定自身与第二终端满足邻近通信条件；第一终端将特定IP流切换到自身与第二终端的邻近通信路径，并通过自身与第二终端的邻近通信路径，传输特定IP流；其中，特定IP流为第一终端与第二终端之间传输的部分或全部IP流，从而实现了IP流在经由核心网路由的通信路径与邻近通信路径之间进行切换。
摘要（英）：

Disclosed are an IP switching method and device for solving the problem of implementing the switching of part of an IP stream from an EPC-routed communication path to a neighboring communication path. Embodiments of the present application comprise: a first UE determines according to an ANDSF policy a preferred transmission path corresponding to a specific IP stream to be a neighboring communication path, and determines that the first UE and a second UE satisfy a condition for neighboring communication; a first UE switches the specific IP stream to a neighboring communication path of the first UE and the second UE, and transmits the specific IP stream by means of the neighboring communication path of the first UE and the second UE; the specific IP stream is a partial or complete IP stream transmitted between the first UE and the second UE. The switching of an IP stream from a core network routed communication path to a neighboring communication path is thereby achieved.
