Question: What is the purpose of the "Time Period the Requested IP Throughput Cannot be Achieved in the Cell" measurement in E-UTRAN performance management?
Option 1: To measure the time period during which the UE is in idle mode.
Option 2: To evaluate the quality of provided services to end users in observed cells by comparing IP throughput with guaranteed bit rates of GBR services.
Option 3: To monitor the number of UEs connected to the cell.
Option 4: To measure the time period during which the eNB is experiencing high traffic.
Explanation: The correct answer is Option 2 because the measurement is used to evaluate the quality of provided services to end users in observed cells by comparing IP throughput with guaranteed bit rates of GBR services, as stated in paragraph b) and i). This measurement provides insights into the time period during which the requested IP throughput cannot be achieved in the cell, helping operators to identify potential issues with their network.
