Question: What is the purpose of including the Serving PLMN rate control Information Element (IE) in a message?
Option 1: To indicate the maximum number of downlink ESM DATA TRANSPORT messages the network can send per hour.
Option 2: To specify the minimum number of uplink ESM DATA TRANSPORT messages the UE must send per minute.
Option 3: To inform the UE of the maximum number of uplink ESM DATA TRANSPORT messages it is allowed to send per 6-minute interval.
Option 4: To negotiate the quality of service for a specific bearer.
Explanation: The Serving PLMN rate control IE is used by the network to limit the number of uplink ESM DATA TRANSPORT messages, including User data container IEs, that the UE can send within a specified time interval (6 minutes). This helps prevent overload and ensures efficient use of network resources.
