eNodeB V100R005C00 KPI Reference 1 Overview



1-1

1 Overview

With the initial target of downlink peak data rate reaching above 100 Mbit/s, the

next-generation Long Term Evolution (LTE) system is developed to meet the increasing

demands on higher data rate due to fast expansion of multimedia applications. For a new

wireless system like the LTE, a set of Key Performance Indicators (KPIs) are defined for the

evaluation of system performance, in particular the performance of the evolved Radio Access

Network (eRAN). The comparison between the LTE and the legacy systems such as UMTS or

CDMA2000 system is also specified in this document.

This document specifies a set of eRAN KPIs to evaluate the performance of the LTE system.

Some counters necessary for the KPI calculation are also described in details. Given that the

LTE is a new system, the KPIs in this document are drafted ones and subject to change. KPIs

should be updated according to the experiences of commercial network management and

radio network optimization.

The KPIs in this document are classified into categories based on the measurement targets:

accessibility, retainability, mobility, service integrity, utilization, availability, and traffic KPIs.

This document is organized as follows: firstly we briefly describe the KPI specification

template. Then detailed specifications of each KPI are described in terms of the

aforementioned seven categories. Finally we provide definitions of relevant counters in

Chapter 11 Counter List.

eNodeB V100R005C00 KPI Reference 2 Template for KPI Definition

According to the template, the KPI is defined in terms of the following items. Each KPI has

several sub-clauses.

KPI name (clause header)

It is a descriptive name of the KPI.

Descriptions

It provides a brief overview of the KPI.

Measurement scope

It specifies the KPI monitoring scope. In general, the measurement is made in terms of

cells. The KPI value reflects the performance in a cell or a cluster. The associated

counters can be obtained from cell statistics. In this document, cluster indicates a group

of cells selected by user.

Formula

It is used to calculate the KPI. Generally the formula consists of several counters that are

specified in other sub-clauses.

Associated counters

It contains counters used in the formula. Chapter 11 Counter List provides the counter

descriptions.

eNodeB V100R005C00 KPI Reference 3 Accessibility KPIs



3-1

3 Accessibility KPIs

Accessibility KPIs are used to measure the probability whether services requested by a user

can be accessed within specified tolerances in the given operating conditions. The service

provided by the E-UTRAN is defined as EPS/ERABs. Radio Resource Control (RRC)

connection and System Architecture Evolution (ERAB) setup are the main procedures for

accessibility KPIs. The accessibility KPIs can be calculated per cell or cluster. The KPIs at the

cluster level are calculated by aggregating all cell counters of the same cluster.

3.1 RRC Setup Success Rate (Service)

3.1.1 Description

According to Reference[1]

, the RRC connection setup procedure is triggered by various

different causes as identified by the “establishmentCause” field in RRCConnectionRequest

message: emergency, highPriorityAccess, mt (Mobile terminating)-Access, mo (Mobile

Originating)-Signaling, and mo-Data. The UE sets the establishmentCause in accordance with

the information received from upper layers. Causes except mo-signaling are categorized as

service-related ones. The mo-signaling cause is a signaling-related cause. This KPI evaluates

the RRC setup success rate with service-related causes in a cell or cluster Involved.

The KPI is calculated based on the counters measured at eNodeB when the eNodeB receives

an RRC Connection Request from the UE, as shown in Figure 3-1. To illustrate the KPI

calculation procedures, we briefly discuss how the related counters (number of RRC

Connection setup attempts (service) and number of successful RRC setup (service)) are

collected. The number of RRC Connection attempts is collected by the eNodeB at

measurement point A and the number of successful RRC connection is counted at

measurement point C. The related counters are discussed in Chapter 11 Counter List.

3.2.1 Description

This KPI evaluates the RRC setup success rate of the signaling-related cause (mo-signaling)

in a cell or a cluster.

Like the RRC Setup Success Rate (service), this KPI is used to calculate the RRC setup

success rate only when the “establishmentCause” field is set to mo-signaling in a cell or a

cluster.

3.3 ERAB Setup Success Rate (VoIP)

3.3.1 Description

This KPI is used to evaluate the ERAB setup success rate of the VoIP service in a cell or a

cluster.

The counters related to this KPI are measured when the eNodeB receives an ERAB Setup

Request message or an Initial Context Setup Request message from the MME, as shown in

Figure 3-2 according to Reference [2]

and Reference [3]

. The ERAB is part of the Evolved

Packet Service (EPS) bearer. According to Reference [4]

, an ERAB is one or more Service

Data Flows between UE and EPC. The ERAB identity remains unique for the UE even if the

UE-associated logical S1-connection (S1 bearer) is released during periods of user inactivity.

The ERAB consists of both ERAB radio bearer (between eNodeB and UE, same as the radio

bear defined in the EPS bearer) and corresponding S1 bearer (between eNodeB and MME).

Figure 3-2 and Figure 3-3 show two scenarios: MME-initiated ERAB setup (Scenario A) and

UE-triggered ERAB setup (Scenario B). Scenario B is triggered by the radio bearer setup.

Initial Context Setup Request messages are exchanged between eNodeB and MME. If the

ERAB Setup Request message or Initial Context Setup Request message requires multiple

ERAB setups at the same time, specific counters are incremented for each ERAB .




3-4

Figure 3-2 Measurement point for MME-initiated ERAB setup

Figure 3-3 Measurement point for UE-triggered ERAB setup




3-5

Number of ERAB Connection setup attempts is collected by the eNodeB at measurement

point A and the number of successful ERAB connections is counted at measurement point B,

as shown in Figure 3-2 and Figure 3-3. Note that the eNodeB needs to specify the Quality of

Service (QoS) Class Identifier (QCI) for VoIP in the ERAB setup message.

The voice service can be identified by the QoS information, in particular the QCI in the

ERAB Setup Request message. In general, QCI 1 is assigned to the voice service.

3.3.2 Definition

The ERAB setup success rate (VoIP) KPI is defined in Table 3-3. Note that the ERAB setup

attempts (VoIP) and the successful ERAB setup counters (VoIP) are collected based on the

descriptions in Section 3.3.1 .

4-1

4 Retainability KPIs

Retainability KPIs are used to evaluate the network capability to retain services requested by

a user for a desired duration once the user is connected to the services. These counters can be

calculated per cell or per cluster. The KPIs at the cluster level can be calculated by

aggregating all the cell counters. Retainability KPIs are important in evaluating whether the

system can maintain the service quality at certain level.

4.1 Call Drop Rate (VoIP)

4.1.1 Description

This KPI can be used to evaluate the call drop rate of the VoIP service in a cell or a cluster.

The call drop rate is calculated by monitoring the VoIP ERAB abnormal release rate. Each

ERAB is associated with the QoS information. The voice service can be distinguished by the

specific QCI = 1.

ERAB includes both the ERAB radio bearer and corresponding S1 bearer. Any abnormal

release on either bearer causes call drop and therefore is counted into the call drop rate. The

abnormal release is identified by the CauseIE defined in Reference[3]

. The Call Drop Rate

(CDR) is defined as Abnormal ERAB release / All released ERAB.

Note that there are two different procedures indicating the ERAB release: they are indicated

through E-RAB Release Indication and UE Context Release Command as shown in Figure

4-1.




4-2

Figure 4-1 Abnormal ERAB release

As shown in Figure 4-1, the abnormal ERAB release counter is incremented when the

eNodeB sends an E-RAB Release Indication to the MME or receives an UE Context Release

Command message from the MME and the release causes are not Normal Release, User

Inactivity, Partial Handover, or Handover triggered. If the message contains several ERAB ID

IEs (in the ERAB to Be Release List IE), the counter will be incremented for each individual

ERAB.

For the eNodeB-initiated abnormal ERAB release, the eNodeB knows whether it is a normal

or abnormal ERAB release.

eNodeB V100R005C00 KPI Reference 5 Mobility KPIs



5-1

5 Mobility KPIs

Mobility KPIs are used to evaluate the performance of E-UTRAN mobility, which is critical

to the customer experience. Several categories of mobility KPIs are defined based on the

following handover types: intra-frequency, inter-frequency, and inter-Radio Access

Technology (RAT).

5.1 Intra-frequency Handover Out Success Rate

5.1.1 Description

This KPI can be used to evaluate the intra-frequency Handover out success rate in a cell or a

cluster. The intra-frequency handover (HO) includes both inter-eNodeB and intra-eNodeB

scenarios. To illustrate the KPI calculation, we briefly discuss how the related counters

(number of intra-frequency HO attempts and number of successful intra-frequency HO

attempts) are collected.

Intra-eNodeB HO scenario is shown in Figure 5-1. The HO attempt counter is collected at

point B. When the eNodeB sends an RRCConnectionReconfiguration message to the UE, it

decides to perform a handover. The eNodeB counts the number of attempts to perform

intra-eNodeB intra-frequency HO in the source cell. The success HO counters are collected at

point C. The eNodeB counts the number of successful intra-eNodeB intra-frequency HOs in

the source cell when the eNodeB receives the RRCConnectionReconfigurationComplete

message from the UE.




5-2

Figure 5-1 Scenario for Intra-frequency Intra-eNB HO

Two scenarios are available for the inter-eNodeB HO, as shown Figure 5-2 and Figure 5-3.

The HO attempts are collected at point B. When the Source-eNodeB (S-eNodeB) sends an

RRCConnectionReconfiguration message to the UE, it decides to perform an inter-eNodeB

HO. In this KPI, the source and target cells of the handover are at the same frequency. The

number of inter-eNodeB intra-frequency HO attempts is measured at the source cell.

The number of inter-eNodeB intra frequency success HOs is collected at point C as shown in

Figure 5-2 and Figure 5-3. During a handover with the source and target cells at the same

frequency, the number of successful inter-eNodeB intra-frequency HOs is measured in the

5.2 Inter-frequency Handover Out Success Rate

Similar to Intra-frequency Handover Out Success Rate, the target eNodeB and source eNodeB

are at different frequencies.

5.2.1 Description

This KPI can be used to evaluate the inter-frequency handover out success rate in a cell or a

cluster. Note that the measurement points for the associated counters are the same as those for

the intra-frequency HO scenario described in 5.1.1 . The target LTE cell operates at the

frequency different from that of the source LTE cell, which is the only difference.

As shown in Figure 5-1, if the source and target cells at different frequencies are controlled by

the same eNodeB, the eNodeB counts the number of intra-eNodeB inter-frequency HO

attempts at point B and the successful intra-eNodeB inter-frequency HOs at point C in the

source cell. As shown in Figure 5-2, if the handover source and target cells are at different

frequencies, the eNodeB counts the number of inter-eNodeB inter-frequency HO attempts at

point B and the successful intra-eNodeB inter-frequency HOs at point C in the source cell.

5.2.2 Definition

The inter-frequency handover out success rate is defined in Table 5-2. Note that the HO

5.3 Handover In Success Rate

5.3.1 Description

This KPI can be used to evaluate the handover in success rate in a cell or a cluster. The HO

includes both inter-eNodeB and intra-eNodeB scenarios. To illustrate the KPI calculation, we

briefly discuss how related counters (number of HO attempts and number of successful HOs)

are collected.

Intra-eNodeB HO scenario is shown in Figure 5-4. The HO attempt counters are collected at

point B. When the eNodeB sends an RRCConnectionReconfiguration message to the UE, it

decides to perform a HO. The eNodeB counts the number of intra-eNodeB handover attempts

in the target cell. The success HO counter is collected at point C. The eNodeB counts the

number of successful intra-eNodeB HOs in the target cell when the eNodeB receives an

RRCConnectionReconfigurationComplete message from the UE.




5-5

Figure 5-4 Intra-eNodeB HO

Two scenarios are available for the inter-eNodeB HO, as shown in Figure 5-5 and Figure 5-6.

The HO attempts are collected at point B in the target cell when the T-eNodeB sends a

Handover Request Acknowledge message to the S-eNodeB or the MME. The number of

successful inter-eNodeB HOs is measured in the target cell at point C when the T-eNodeB

receives an RRCConnectionReconfigurationComplete message from the UE.
