个人在学习5G标准3GPP TS 23501-g51过程中，也发现google的机器翻译实在晦涩难懂，所以个人在借助百度翻译（中国人更懂中文）的同时，人工对每句话进行了校对。

在自己学习的同时，也将翻译内容分享给给广大网友。由于个人能力有限，翻译不到位的地方还请各位网友们指正。

4.4.5 Application Triggering Services

See TS 23.502 [3] clause 5.2.6.1.

Application trigger message contains information that allows the network to route the message to the appropriate UE and the UE to route the message to the appropriate application. The information destined to the application, excluding the information to route it, is referred to as the Trigger payload. The Trigger payload is implementation specific.

应用程序触发消息包含允许网络将消息路由到适当的UE和UE将消息路由到适当的应用程序的信息。目的地为应用程序的信息（不包括路由该应用程序的信息）称为Trigger负载。Trigger负载是特定于实现的。

NOTE: The application in the UE may perform actions indicated by the Trigger payload when the Triggered payload is received at the UE. For example initiation of immediate or later communication with the application server based on the information contained in the Trigger payload, which includes the PDU Session Establishment procedure if the related PDU Session is not already established.

注意：当在UE处接收到Trigger的有效载荷时，UE中的应用可执行由Trigger有效载荷指示的动作。例如，基于包含在Trigger有效载荷中的信息发起与应用服务器的即时或稍后通信，如果相关PDU Session尚未建立，则包括PDU Session Establishment过程。
