Application identifier determination method, application data transmission method and related products

The embodiment of the invention discloses an application identifier determination method, an application data transmission method and related products, and the application identifier determination method comprises the steps that a terminal determines an application identifier corresponding to a first application from a plurality of candidate application identifiers according to the associated information of the first application, different application identifiers in the plurality of candidate application identifiers correspond to different path descriptors, and the associated information is used for indicating identity information of the first application. According to the embodiment of the invention, the terminal can determine the application identifier corresponding to the path descriptor for the application, thereby facilitating the realization of network slicing. 本申请实施例公开了一种应用标识符确定方法、应用数据传输方法及相关产品，该应用标识符确定方法包括：终端根据第一应用的关联信息，从多个候选应用标识符中确定出该第一应用对应的应用标识符，该多个候选应用标识符中不同应用标识符对应不同的通路描述符，该关联信息用于指示该第一应用的身份信息。本申请实施
