Question: In a 5G system, which of the following types of information is collected for network optimization subject to user consent?
Option 1: Network conditions (e.g., network load, congestion) and application characteristics (e.g., expected traffic over time)
Option 2: Information on served UEs (e.g., access type, cell type, user experienced data rate) and prioritized communication details
Option 3: Enhanced traffic characteristics of UE (e.g., Mobility information, location, sensor-level information, application-level information)
Option 4: Only network load and congestion information for real-time optimization
Explanation: The collection of enhanced traffic characteristics of UE (such as mobility information, location, sensor-level information, and application-level information) for network optimization in a 5G system is subject to user consent, distinguishing it from other types of information that are collected without such stipulation, highlighting the importance of privacy and user agreement in handling more sensitive, detailed user and device data.
