Question: What is the purpose of including the Traffic Flow Template (TFT) IE in a message?
Option 1: To request a new Quality of Service (QoS) profile from the network.
Option 2: To transfer extra parameters to the User Equipment (UE).
Option 3: To request a new TFT or modification of an existing TFT, or transfer extra parameters such as the Authorization Token to the network.
Option 4: To notify the network about changes in the UE's IP address.
Explanation: The correct answer is Option 3 because including the TFT IE in a message allows the UE to request a new TFT, modify an existing one, or transfer additional parameters like the Authorization Token to the network. This is essential for efficient traffic management and QoS control in mobile networks.
