Question: What is the purpose of Small Data Rate Control in a PDU session?
Option 1: To limit the rate at which the UE generates uplink user data messages to comply with the network's policy.
Option 2: To increase the amount of data that can be sent by the UE during a PDU session.
Option 3: To prioritize certain types of data over others in a PDU session.
Option 4: To terminate a PDU session if the UE exceeds a certain data rate threshold.
Explanation: Small Data Rate Control is used to control the maximum number of uplink user data messages sent by the UE in a time interval for a PDU session, as specified in 3GPP TS 23.501. The purpose of this control is to limit the rate at which the UE generates uplink user data messages to comply with the network's policy, thereby preventing excessive data usage and ensuring fair resource allocation among users.
