1 OverviewWith the initial target of downlink peak data rate reaching above 100 Mbit/s, thenext-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 newwireless 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 AccessNetwork (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. KPIsshould 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 specificationtemplate. Then detailed specifications of each KPI are described in terms of the
aforementioned seven categories. Finally we provide definitions of relevant counters inChapter11 Counter List.

3 Accessibility KPIsAccessibility KPIs are used to measure the probability whether services requested by a usercan 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 thecluster 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 variousdifferent 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 withthe information received from upper layers. Causes except mo-signaling are categorized asservice-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 receivesan RRC Connection Request from the UE, as shown inFigure 3-1.To illustrate the KPI
calculation procedures, we briefly discuss how the related counters (number of RRCConnection 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 atmeasurement point C. The related counters are discussed in Chapter11 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 setupsuccess 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 acluster.
The counters related to this KPI are measured when the eNodeB receives an ERAB SetupRequest message or an Initial Context Setup Request message from the MME, as shown inFigure 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 theUE-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 andFigure 3-3 show two scenarios: MME-initiated ERAB setup (Scenario A) andUE-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 theERAB Setup Request message or Initial Context Setup Request message requires multiple
ERAB setups at the same time, specific counters are incremented for each ERAB .

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 inFigure 3-2 andFigure 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 theERAB 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 inTable 3-3.Note that the ERAB setup
attempts (VoIP) and the successful ERAB setup counters (VoIP) are collected based on thedescriptions in Section3.3.1 .

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. EachERAB 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 abnormalrelease 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 inFigure
4-1.

Figure 4-1Abnormal ERAB release
As shown inFigure 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 ReleaseCommand 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 IDIEs (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 normalor abnormal ERAB release.

5 Mobility KPIsMobility KPIs are used to evaluate the performance of E-UTRAN mobility, which is criticalto the customer experience. Several categories of mobility KPIs are defined based on the
following handover types: intra-frequency, inter-frequency, and inter-Radio AccessTechnology (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 inFigure 5-1.The HO attempt counter is collected atpoint 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 atpoint C. The eNodeB counts the number of successful intra-eNodeB intra-frequency HOs inthe source cell when the eNodeB receives the RRCConnectionReconfigurationComplete
message from the UE.

Figure 5-1Scenario for Intra-frequency Intra-eNB HO
Two scenarios are available for the inter-eNodeB HO, as shownFigure 5-2 andFigure 5-3.The HO attempts are collected at point B. When the Source-eNodeB (S-eNodeB) sends anRRCConnectionReconfiguration 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 andFigure 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 thesource cell when the S-eNodeB receives a UE Context Release message from the
Target-eNodeB (T-eNodeB) or a UE Context Release Command message from the MME,indicating that the UE access to the T-eNodeB is successful.

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 forthe intra-frequency HO scenario described in5.1.1 .The target LTE cell operates at thefrequency different from that of the source LTE cell, which is the only difference.
As shown inFigure 5-1,if the source and target cells at different frequencies are controlled bythe same eNodeB, the eNodeB counts the number of intra-eNodeB inter-frequency HOattempts at point B and the successful intra-eNodeB inter-frequency HOs at point C in the
source cell. As shown inFigure 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 atpoint B and the successful intra-eNodeB inter-frequency HOs at point C in the source cell.

11 Counter ListTable 11-1provides a counter list including all counters relevant to the KPI calculation. Ineach KPI specification, one or several parameters are used to calculate the KPI as shown in
the KPI formula. Each parameter is mapped to a counter. For details on each counter, see theReference
[6].
Note that only QCI 1 is for VoIP service (conversational voice). According to Table6.1.7 in
Reference[5]
, QCI 7 can also be assigned to non-conversational voice. In this document, QCI7 is not considered as the VoIP service in the KPI calculation.
