Question: What is the primary purpose of the "Distribution of Abnormally Released Call (QCI1 E-RAB) Duration" measurement in Performance Management (PM)?
Option 1: To measure the time taken for successful establishment of QCI1 E-RAB via initial Context setup or additional E-RAB setup procedure.
Option 2: To provide a histogram result of samples related to abnormally released call (QCI1 E-RAB) duration, excluding time periods with ongoing RLF or user inactivity timer.
Option 3: To measure the packet loss rate in the Evolved Universal Terrestrial Radio Access Network (E-UTRAN).
Option 4: To monitor the number of handovers initiated by the eNB or EPC.
Explanation: The correct answer is Option 2 because the primary purpose of this measurement is to provide a histogram result of samples related to abnormally released call (QCI1 E-RAB) duration, which helps in understanding the distribution of abnormal release causes and their impact on network performance. This information can be used by operators to optimize network configuration and improve overall network efficiency.
