The present invention is a method and a system for bearer authorization in a wireless communication network, including the creation of an authorization binding information (AUTN) in a control function (PCF) of an application layer of the wireless communication network, the allocation of a control function identifier representative of the actual address of the control function in the wireless communication network and incorporating said identifier into the authorization binding information, the transmission of the so created authorization binding information to a terminal device (UE) having access to the wireless communication network, and the bearer authorization proceeding from the terminal device through a transport layer of the wireless communication layer by deriving the actual address of the control function from which the authorization binding function has originated based on the control function identifier included in the authorization binding information. In this manner, inherent security risks involved in sending the actual control function address to a terminal device or User Equipment are eliminated, and the authorization binding information is reduced in size.
