1 Introduction

1.1 Purpose This document is intended to define UTRAN Key Performance Indicators, which give information about quality, performance, load, capacity, .. in a uniform way to the operator.

These indicators may be used for the following purposes:

Definition of formulas, which are used for realization of predefined reports in the PM+ application of the O&M Toolset (i.e. SPOTS),

1.2 Definition of terms Each KPI will be described by the following fields:

Long name

This field contains the name of the described KPI.

Short name

This field contains an acronym for the described KPI

Description

This field contains a short explanation of the KPI.

Formula

This field contains the formula for calculation of the KPI.

Counters

This field contains the counters used for calculation of the KPI. Counters are described by the shortname of the measurement and, in brackets, the index of the used counter. The indices are listed with the following meaning: - measType[i] Counter with index #i is used - measType[i,j,k] Counters with indices #i, #j, #k are summarized - measType[i-j] Counters in the index range #i to #j are summarized - measType[all] All counters of the measurement are summarized - measType[i][j] Counter related to index #i with sub-counters index #j are

used. E.g. index[j] related to CS defined with index #i

Note: An Index is represented by x,y,z, where x represents the protocol type, y represents the cause categorization and z represents the cause value (see [2]. If specific indices are listed, only the cause values are listed.



Elementary object

This field contains the measured object class the KPI is applicable to. For UMR2.0, this field will only contain the objects “RNC”, “cell”, “adjacent cell relation”, “adjacent GERAN cell relation”.

Unit/Range

This field contains unit and/or range related to the KPI, e.g. percent.

Remark

This field contains additional information.

1.3 General Principles

(n-1) out of n approach

Measurements can be split in 3 sub-measurements – number of attempts, number of successes and number of failures – where any of the three measurements can be calculated from the two others.

# of Success + # of Failures = # of Attempts

SuccessRate + FailureRate = 100%

SuccessRate + FailureRate + DropRate = 100%

For procedure related KPI analysis it will be defined the Success Rate and the Failure Rate if possible. In case of Hard handover or Inter-System handover a drop rate is added which indicates a failed handover procedure with the consequence that the connection is lost.

According the formulas depicted above, one of the rates could be calculated if the other value(s) are known. However, since the measurement recording within the network entities may be out of balance due to failed counting or in case attempts and successful/failed cases are counted within different granularity periods, the adding of the indicated rates may not be exactly 100% in all cases. It will be therefore indicated all rate cases within the document to be able to make a double check of the counters.

Cause relations

For determination of per-cause values the following rules shall apply:

][#][#

][InitCauseofAttempts

InitCauseofSuccInitCauseeSuccessRat =

][#][#

][AllCausesofAttempts

seFailureCauofFailuresseFailureCaueFailureRat =



In case of the Success Rate per init cause, the number of success is related to the number of attempts, where in both terms the init cause shall apply.

In case of the Failure Rate per dedicated failure cause, the number of failures is related to the number of attempts, where the dedicated failure cause is related to all causes of the attempts.

The difference of these calculation rules is based on the target group that evaluates the KPI.

The success rates of a procedure refers mainly to Network Planning / Network Optimization groups where the success rate related to the dedicated initialization cause is focused. Thus, e.g. the success rate of the RAB establishment for each QoS class may be depicted in a diagram as follows:

82%

84%

86%

88%

90%

92%

94%

Convers. Streaming Interactive Background

Success Rate

Fig. 1.1 Success rates of QoS classes

The dedicated FailureRates of a procedure is mainly used for Troubleshooting. Within this KPI document the definition the ratios of the individual failure causes are depicted related to all attempts. All failure rates per cause added up result in the total failure rate. Of course the indication of the failure rate per initial cause would be advantageous, but this is not possible. In case a failure occur the context of the initialization cause would have to be created which results in a lot of effort and a higher number of measurement counters since for each initialization cause the failure cause has to be stored separately.

Granularity Period

Within this document it is assumed that the KPI is applicable for the same granularity period as defined for the measurements that are utilized within the formulas. Thus, no recommendation is given related to the GP of the KPI. However, the measurements used within one formula may have been activated within separate scanners where different GPs may have been activated. In such a case the O&M Toolset shall consider the different GPs and aggregate the measurements with the lower GPs until the same GP for all measurements apply.



Call versus Connection

Within this document KPIs will be defined analyzing calls and analyzing connections. In our approach calls will be analyzed if a RAB establishment/release is involved. Thus, a call is not related only to a voice connection but also to PS connections.

If in the concerned measurements it cannot be distinguished if a RAB is involved or not, e.g. within the iuRelReq counter, then the behavior of connections will be analyzed. I.e. the connection may be related to a “call” or to signaling only due to SMS transmission or due to Location updates.



2 Call/Connection Analysis

2.1 Call Establishments

General assumption:

In reference to 3GPP TS 25.931, a call setup will be described by the concatenation of the phases

1. RRC connection establishment (cf. 3GPP TR25.931, chapter 7.3) -> covered by measurements rrcEstabAtt, rrcEstabSucc, rrcEstabFail

2. NAS signaling connection establishment (cf. 3GPP TR25.931, chapter 7.2) -> pure pass-through of Initial Direct Transfer message; success rate=100% assumed

3. RAB establishment (cf. 3GPP TR25.931, chapter 7.6) -> covered by measurements rabEstabAtt, rabEstabSucc, rabEstabFail

Remark, that these phases refer to the UE in IDLE mode, but it is possible to have several RAB establishments in the same RRC connection.

2.1.1 Call setup success rate Remark, that for the indicated success rate only UTRAN failures are taken into account. In case the Core Network rejects the establishment request from the UE due to internal checks, UTRAN is not able to know the failed NAS procedure.

Remark, in UMR2.0 following RAB establishment causes are not supported:

1-0 CS streaming

2-0 CS interactive

3-0 CS background

0-1 PS conversational

1-1 PS streaming

Long name a) Call setup success rate (Access probability) b) User setup success rate (Access probability) c) User setup success rate (multi RAB assignment)

Remark The main difference between call setup and user setup success rate is that with the USSR only the failures due to congestion are supposed to impact the access probability in the user perspective.

2.2 Connection Release Analysis

2.2.1 CN originated release analysis “Connection release analysis CN originated ” investigates the release causes on connection releases from CN.

By these KPIs the normal connection releases and un-normal connection releases i.e. connection release due to failure from CN side or UTRAN side shall be distinguished.

2.2.2 UTRAN originated release analysis “Connection release analysis UTRAN originated ” refers only to un-normal releases UTRAN originated i.e. existing connections have been lost at UTRAN side. KPIs in this subsection analyze the connection drop rates by means of release indication toward the CN and the RRC connection drop rate.

2.2.2.1 Connection Drop Analysis The un-normal release of a connection UTRAN originated is indicated either by the RAB RELEASE REQUEST message or the IU RELEASE REQUEST message transmitted from the RNC to the CN. The RAB RELEASE REQUEST message will be used when the failure occurs in the RAB management as e.g. “firmware failure PRLC, DHT,..”. In any case the UE is still reachable via a RRC connection. The IU RELEASE REQUEST message is used in case the UE is lost at the air interface. The CN will response either with the RANAP message RAB ASSIGNMENT REQUEST indicating the RAB to be released if another parallel transaction is still ongoing or with the IU RELEASE COMMAND message.

Fig. 2.1 Release Request message and command flow



For evaluation of the connection drop rates following aspects have to be considered impacting the KPI result:

• If the dropped connection was related to a call or to a signaling connection, which was established for registration or signaling, cannot be distinguished. I.e. service related call drops, which are intentionally preferred to measure, cannot be distinguished from RRC connections dropped by UTRAN.

• In case the transmitted RAB RELEASE REQUEST message from the RNC to the CN will be acknowledged by the RAB ASSIGNMENT REQUEST message from the CN because a parallel transaction is still running, the rabRel counter in UMR2.0 will count the same event twice.

• In case that the established connection is in Softer/Soft handover when the connection loss occur and the RNC transmits the RAB RELEASE REQUEST message the rabRel counter will be incremented in all cells of existing radio links. Thus, including the rabRel counter in the drop rate calculation means that the drop rate is calculated depending the existing radio links and not per RAB establishments.

As a consequence of the falsification by the rabRel counter, the rabRel counter is not considered for the drop analysis toward the CN. Thus, the calculated drop rate is not quite correct but the drops caused from internal RNC failures should be much less compared to the loss of the UE.

5.2 Soft Handover

5.2.1 Soft Handover rate

Long name Soft handover rate Short name SHORate(RLN) Description This indicator will give you the percentage rate of UEs with 1, 2 or 3 radio links per

active link set size. Formula

Object Cell Unit/Range Percent Remark Since in UMR2.0 the periodicity is 5 minutes the actual value of the number of active

links per link set size are considered this calculation gives only a rough indication of the soft handover rate.



5.3 Relocations

5.3.1 Number of outgoing relocations See measurement type description in appendix: “relocOutAtt[all]”

5.3.2 Number of incoming relocations See measurement type description in appendix: “relocIncAtt[all]”

5.3.3 Outgoing Relocation per Call rate

established calls. Formula

Object RNC Unit/Range Percent Remark In a normal sequence first the RAB will be established and later on the outgoing

relocation may occur. Thus, it may occur that the RAB Establishment may be measured within an earlier GP than the outgoing relocation procedure is measured. This applies especially in case of PS calls. The mean number of outgoing relocations per call should therefore be considered in a greater period, e.g. per day.



5.4 Hard Handover

5.4.1 Outgoing Hard Handover per call rate

Object RNC Unit/Range None Remark In a normal sequence first the RAB will be established and later on the outgoing hard

handover may occur. Thus, it may occur that the RAB establishment may be measured within an earlier GP than the outgoing hard handover procedure is measured. This applies especially in case of PS calls. The mean number of outgoing hard handover per call should therefore be considered in a greater period, e.g. per day. In addition it should be considered that by a previous Soft Handover the originating cell of the hard handover may not be the cell where the RAB establishment has been performed and measured. Therefore the Outgoing Hard Handover per call rate should is related to the RNC instead to a cell.



5.5 Inter System Handover

5.5.1 Outgoing CS Inter System Handover per call rate

In a normal sequence first the RAB will be established and later on the inter system hard handover may occur. Thus, it may occur that the RAB establishment may be measured within an earlier GP than the outgoing inter system handover procedure is measured. This applies especially in case of PS calls. The mean number of outgoing hard handover per call should therefore be considered in a greater period, e.g. per day.

In addition it should be considered that by a previous Soft Handover the originating cell of the hard handover may not be the cell where the RAB establishment has been performed and measured. Therefore the Outgoing Inter System Handover per call rate may be related better to the RNC instead to a cell.
