1 Introduction

1.1 This document

This document relates how the metrics reported in the AT&T ANOVA report are calculated

based on the default/standard Actix event definitions & attributes.

The definitions of the underlying attributes are explained in Appendix B.

1.2 Device filtering

Although this is not specifically mentioned in the metric definitions, all metrics are filtered

per device type within the reported metrics.

This means that, unless otherwise specified, the reported metric is based on only a single

device type.

1.3 Location filtering

Although this is not specifically mentioned in the metric definitions, all metrics are filtered

to only include attributes & events which occurred within the geographical location of the

user selected polygon area. This selection is dynamic within the report and all metrics will

be updated according to the user selected polygon(s).

1.4 Graphs

All graphs are based on Binned data.


2 Selection Sheet This purpose of this sheet is to give an overview of the drive test configuration and

parameters. This sheet is also used to make user selections to filter data based on cluster

polygon boundaries.

2.1 Pie Charts

All of the charts are based on the selected stream label.

2.1.1 Cluster split time

The percentage of time the UE spent within each cluster.

Metric = sum(Time)

where state(ATT_LEX_ClusterName)=x

2.1.2 Technology split

The percentage of time the UE spent in each technology mode.

Metric = sum(Time)

where state(Technology_Mode)=x

2.1.3 Application split time

The percentage of time the UE spent performing each application task type.

Metric = sum(Time)

where state(Task_Application_Type)=x


3 Gating Sheet The purpose of this sheet is to list all gating KPIs. All statistics are filtered based on the

cluster selection made in the SELECTION sheet. The gating targets are set based on the

drive test configuration and scope as indicated by the filename.

3.1 Pie Charts

All of the charts are based on the selected stream label.

3.1.1 LTE RRC state

The percentage of time the UE spent within each cluster.

Metric = sum(Time)

where state(LTE_RRCConnection_State)=x

3.1.2 Data Radio Mode

The percentage of time the UE spent in each technology mode.

Metric = sum(Time)

where state(Data_Radio_Mode)=x

3.1.3 WCDMA RRC state

The percentage of time the UE spent performing each application task type.

Metric = sum(Time)

where state(Uu_RRC_Messagebased_State)=x

3.2 Radio Overview

This section contains Gating KPIs related to the RF environment.

3.2.1 User experience number of iterations

The number of times the data UE completed a complete script cycle.

Metric = count(1)

Filter = Event_Task_Start AND state(ATT_LEX_Task_Application_Type)==33

3.2.2 CS number of iterations

The number of times the voice UE completed a complete script cycle.

CSFB UEs


Metric = count(1)

Filter = LTE_Event_CSFB_CallAttempt and (state(ATT_LEX_In_Task)==1) AND

(state(LTE_CSFB_Call_Direction)==0)

Note:

ATT_LEX_In_Task is a custom AT&T attribute. It is set to 1 when an application task

begins, and 0 when the task ends.

WCDMA UE

Metric = count(1)

Filter = Uu_OutgoingCallOk OR Uu_IncomingCallOk OR Uu_IncomingCallSetupFail

OR Uu_OutgoingCallSetupFail

3.2.3 Time on LTE

This percentage of time each UE spent in LTE technology mode.

Metric = sum(t1)/(sum(t1) + sum(t2)) (%)

t1 = Time with state(Technology_Mode)==5
