Question: What is the purpose of the "Attempted outgoing handovers with DRX" measurement in E-UTRAN performance management?
Option 1: To measure the number of successful incoming handovers when DRX is used.
Option 2: To provide the number of attempted outgoing handovers, when DRX is used, for packet switched traffic in EPS.
Option 3: To calculate the average time taken for a UE to complete a handover procedure.
Option 4: To monitor the number of RRCConnectionReconfiguration messages sent to UEs.
Explanation: The "Attempted outgoing handovers with DRX" measurement is used to count the number of attempted outgoing handovers when Discontinuous Reception (DRX) is used, specifically for packet switched traffic in EPS. This measurement helps network operators monitor and optimize handover performance in their E-UTRAN networks.
