LTE Performance KPI Quiz

RRC setup success rate is divided into:

• Service RRC setup success rate

• Message RRC setup success rate

• Signaling RRC setup success rate

• Performance RRC setup success rate

While the E-RAB include E-RAB radio bearer and S1 bearer, but only E-RAB radio bearer abnormal release would lead to dropped calls, and calculated as the call drop rate.

• TRUE

• FALSE

Typically, a performance measurement task must include performance measurement counters, performance measurement object and performance measurement period.

• TRUE

• FALSE

Traffic KPI includes?

• Total number of Radio Bearer;
  Number of Radio Bearer (QCI1s to 9)

• Total UL Traffic Volume;
  UL Traffic Volume (QCIs 1 to 9)

• Total DL Traffic Volume;
  DL Traffic Volume (QCIs 1 to 9)

• Mean UL Throughput (QCIs 1 to 9)

Which of the following is not included in Radio Network KPIs?

• Accessibility KPI

• Retainability

• Mobility

• Service Intergrity

What are the usual RRC setup causes?

• MO_Signaling

• MT_Access

• MO_Access

• Emergency

Which of the following belongs to RRC Connection Reestablishment Failure cause?

• RRC reconfiguration failure

• Handover failure

• No available UE context in eNodeB

• No response from UE

E-RAB setup is triggered when a UE initiates service request on the radio network. E-RAB is setup through Initial-Context-Setup or E-RAB-setup procedures

• TRUE

• FALSE

According to 3GPP TS 32.450, the throughput measurement do not need to remove the data scheduled in the last TTI before the downlink buffer is empty

• TRUE

• FALSE

What are the possible causes of E-RAB Abnormal Release?

• Radio network layer failure

• Transport network layer failure

• Network congestion

• Handover failure
