Introduction to WCDMA RAN Key Performance Indicators

WCDMA RAN Key Performance Indicators

1 Introduction to WCDMA RAN Key Performance Indicators 1.1 Overview of WCDMA RAN key performance indicators Key performance indicators (KPIs) are a set of selected indicators used for measuring the current network performance and trends. KPIs highlight the key factors of network monitoring and warn in time of potential problems. KPIs are also used for prioritizing the corrective actions. The KPIs described here are the basic network level KPIs for the radio network based on WCDMA access technology (WCDMA RAN). The identification of each defined KPI should represent this technology. However, because of practical and historical reasons the KPI IDs follow the rule used in NSN main reporting tool (NetAct Reporting Suite). Each defined KPI has a unique KPI ID that follows the format RNC_xxxxy, where xxxxy represents a given unique ID number. For more details, see Structure of Key Performance Indicators.

g

There are also other KPIs in the NetAct Reporting Suite that use the ID format RNC_xxxxy. Only the KPIs that are defined in this document are recognized by the WCDMA RAN release RU40. All KPIs described here are based on performance counters. The main focus is on formulas. However, some typical values for KPIs are given. Some of the key performance indicators (KPI) are not yet available in the official reporting tools. For more information on available KPIs, see Available WCDMA RAN key performance indicators.

1.1.1 Structure of key performance indicators All the items described for each KPI are based on a common template. The template includes the following items: • • •

• •

16

KPI name: The official name of the KPI. KPI abbreviation: An abbreviation of the KPI name. KPI ID: The WCDMA RAN ID of the KPI. The following format is used for the KPI ID: RNC_xxxy, where xxxy is the unique number and y is the NetAct Reporting Suite version. Only one KPI version at a time is found in the document. From the perspective of this document, what matters is the current version used in the NetAct Reporting Suite. It should be noted that NetAct Reporting Suite versioning always starts with version a. However, this might not always be the case for the document, the documentation for a KPI can also start from a later version (for example, b-version). Description: The official description of the KPI. Note (1-n): Note fields related to the generic KPI description.

Measurement: The description includes a reference to the measurement in question, for example, M1001: Service Level. KPI summarization formula: The formula given in counter numbers. KPI formula with short names: The formula given in short names. Formula note: Note related to the KPI formula. KPI class: Each KPI belongs to a KPI class. The main classes are accessibility, retainability, usage, integrity, and mobility. There can also be additional classification related to each main class. For more information, see Classification of key performance indicators. Unit: The unit of the KPI. The possible values are # (stands for the previously used ‘integer number’), E (stands for the previously used Erlang), minutes, minutes per drop, percentage, dBm, cell/s, kbps, Mbit and Mbps (stands for previously used Mbit/s). Typical values: The defined typical values in accepted (=live) networks for the KPI. See System Program Report. Object Summary Levels: Summary levels of the reported objects. These levels are based on the targets for the RAN measurements that provide the counters belonging to the KPI. – –

Introduction to WCDMA RAN Key Performance Indicators

There are different targets for Radio and Transport measurements. Possible radio measurement values from the smallest to the largest are: RB (Radio Bearer), Cell, LCG (Local Cell Group), Cluster of Cells, BTS (Base Station), RNC, Area, City, and Network. Possible transport measurement values for ATM-based transport from the smallest to the largest are: VCC (Virtual Channel Connection), RNC, and Network. Possible transport measurement values for IP-based transport from the smallest to the largest are: IP Route, RNC and Network.

Object Summary Level notes: This field describes the potential problems for the given Object Summary Level. Time Summary Levels: Summary levels on reporting timescale. Based on the collection periods for the RAN measurement(s). The possible values are: Hour, Day, and Week. Time Summary Level notes: This field states the potential problems for the given Time Summary Level.

1.1.2 Classification of key performance indicators The KPIs are first grouped into four different levels. They are the following: • • • •

Access network RNC function Transport Resource Manager Access point

For more information on the KPI levels, see Different KPI levels. Under each level, the KPIs are grouped into the following categories: • •

The KPIs are grouped according to these categories in each release. Each KPI description also includes the KPI class. Within a class there can be certain KPIs that include an additional classification.

Usage There are the following additional classifications for the Usage category: • • • • • • • •

Resource capacity-based KPIs Resource availability-based KPIs HW resource-based KPIs Resource allocation KPIs Load-based KPIs Throughput-based KPIs Transmission load-based KPIs Duration-based KPIs

Mobility There are no additional classes but for each KPI it should be considered whether the KPI is related to the source and/or target cell.

Integrity There is the following additional class for the Integrity category: • •

Error rate-based KPIs Radio Interference based KPIs

1.1.3 Network and user key performance indicators There are some KPIs defined for the same issue but from two different viewpoints, that is, network and user viewpoints. For such KPIs the differentiation is done in the KPI Name, for example, RRC Setup and Access Complete Ratio, from network perspective.

1.1.4 Summary of different KPI viewpoints The following figure illustrates the different KPI viewpoints.

The two pyramids in the figure illustrate the two perspectives: the network perspective, and the user perspective, that is, the distinction between network and user KPIs. • •

In the upper pyramid you can see the RAN functionalities and the related RAN statistical measurements from the user equipment (UE) perspective. The lower (inverted) pyramid shows the RAN functionalities and the related RAN statistical measurements from the network perspective.

The column on the left shows the classification of the KPIs (KPI Class). In the center part (column), you can see the related RAN measurements. The KPIs are based on the counters found in the RAN measurements. The reference mark for a measurement, for example, Cell Resource [1] indicates that a KPI has been defined for that measurement. The KPI with the required information is described in this documentation set. For counter (and detailed measurement) descriptions of measurements 1-8, 12, 14-18, 20-21 and 26, see RNC Counters - RNW Part. For

Usage – – –

•

Mobility –

•

The availability of resources versus the allocation of the available resources. The load of allocated resources versus the gain (throughput). The data amounts versus the gain (throughput).

Handover in the Source Cell versus the Target Cell

Integrity –

Planned error rates versus achieved error rates

The right column shows the KPI outcome, that is, the issues that the KPI indicates. • • •

Amount of statistical data related to the defined KPIs and classes: When you go down the pyramid, the amount of data increases. Importance of each KPI and KPI class: The top of each pyramid represents the most essential data. Visibility of KPIs in monitoring: The top layers of a pyramid become visible before the lower layers.

1.2 Calls in WCDMA RAN The 3GPP specifications define the 'call' as follows: 'a logical association between several users (this could be connection oriented or connectionless)'. This definition is not useful when you are measuring the call setup and releases in the (RAN part of the) network and/or user perspective. Therefore, you must further define the overall and UTRAN-related 3GPP definitions to be able to make call-related key performance indicators (KPI).

1.2.1 Definition of call from the WCDMA RAN perspective The general UMTS architecture defined by 3GPP places RAN (and BSS) in the Access Domain and it functions as a part of the Access Stratum. The NSS and packet core (PaCo) belong to the Core Network Domain (through the underlaying Serving Network Domain) and their functions are part of the Serving Stratum.

The Access Domain and Core Network Domain form the Infrastructure Domain. The Mobile Terminal (MT) and USIM form the User Equipment (UE) and the UE Domain. The interface (reference point) between the Access and Serving Network Domain is defined as Iu. The interface (reference point) between the UE and the Infrastructure Domain is defined as Uu (=UMTS Radio Interface). There is a direct interface between the UE and Infrastructure Domain. The 'interface' is handled by sending messages over the Access Stratum, but the messages are treated transparently by RAN. There the messages are on the 'Non-Access Stratum' from the RAN perspective. The Access Stratum is defined as follows: 'The access stratum provides services related to the transmission of data over the radio interface and the management of the radio interface to the other parts of UMTS'. The Serving Stratum (that is transparent to RAN) consists of protocols and functions needed to route and transmit data/information (user or network-generated) from the source to the destination. Because the Access Stratum is under the Serving Stratum, everything that occurs between the source and destination (the UEs and/or Servers) is transparent to RAN. Therefore, in RAN, you are restricted to the visible services and their relationships to calls made in the Service Stratum. The Network Services are found in the generic QoS architecture in the 3GPP specifications about QoS.

The services defined (from top-down) are End-to-End, UMTS Bearer, Radio Access Bearer (RAB), Radio Bearer (RB) and physical bearer services. The services that are visible (and handled) by the RAN are the RAB, RB, and physical bearer services. The RAB provides services in the Iu interface and the RB (and physical bearer) provides services in the Uu interface. The QoS Architecture includes the parameters for the services and the mappings between the services. The defined parameters help to find the relationships of the call to each service (layer). The defined calls (and how they are derived from the QoS parameters) are as follows: • • •

Voice: Traffic Class = Conversational; Source Statistics Descriptor = Voice. Other parameters are not relevant. UDI: Traffic Class = Conversational; Source Statistics Descriptor = Unknown. Other parameters are not relevant. Streaming 'call': Traffic Class = Streaming. Other parameters are not relevant. The streaming 'call' can be asked by both core domains.

•

Packet 'call': Traffic Class = Interactive or Background. Other parameters are not relevant.

There can be more than one call, for example, RAB for one user (UE). The 3GPP specifications about Access Stratum define how RAN provides the services.

This means that in addition to RAB and RB, also other factors are relevant. From the call perspective, the connection to RAN is essential, that is, the user needs an access point to use UTRAN services. The UTRAN Access Point for UEs (to the SAPs), such as UTRAN Cell, is defined in 3GPP specifications about UTRAN. If the UE has access to UTRAN, it has the possibility to use the reference points (interfaces, see 3GPP specifications about UMTS architecture) by using the defined protocols. Likewise, in the SAP division (connection establishment/release and RAB establishment/release) there is an important split in managing the connection (such as Control plane) and in managing the service (such as User plane).

Introduction to WCDMA RAN Key Performance Indicators

WCDMA RAN Key Performance Indicators

The connection between the UE and a UTRAN Access Point is the Radio Link (RL), defined in 3GPP specifications about UTRAN. If the UE has access to more than one UTRAN Access points, then it has more than one RLs.

Call definition The following definition can be given for a call: The time when the RAB uses RB(s) having non-zero bit rate (signalling RBs are not taken into account). This means that either dedicated or shared transport channel is allocated for user plane traffic. From the RAB perspective, this definition means that a RAB and a call can be the same thing but alternatively one RAB can handle more than one call.

1.2.2 Call Setup Success rates (CSSR) in NSN-based WCDMA RAN The UE has access to RAN services through the UTRAN Access Point, that is, UTRAN Cell. It does this by using the (radio) RRC protocol procedure RRC Connection Establishment. The RRC protocol is part of the Radio Interface Protocol architecture defined by the 3GPP. The RRC protocol procedure RRC Connection Establishment is described in 3GPP specifications about Radio Resource Control. The first part of the Call Setup Success Rate KPI is the success rate of setting up the related RRC Connection for the call. When looking at the relationship between the RRC and the required service for the desired call, some problems can be found. • •

The setup causes for the RRC do not, in most cases, indicate precisely what kind of service/call is to follow. The service or call that follows the connection setup is not necessarily set up simultaneously with the RRC. This means the service or call that uses non-real time (NRT) type of transmission.

Therefore, some additional definitions and assumptions are needed to be able to define the RRC Setup part of the CSSR KPIs for the following call types: •

• • •

Voice: Because the RRC Setup Causes 'Mobile Originated Call Conversational' and 'Mobile Terminated Call Conversational' do not specify whether the call attempt is AMR or UDI, we must use these causes in CSSR KPI for both AMR and UDI. UDI: See Voice. Streaming ‘Call’: There are unambiguous setup causes for this. Packet 'Call': The 3GPP has not clearly defined how to start a packet 'call'. For this reason, it is extremely difficult to define on the basis of counters all the times when a packet call setup starts. In practice, almost every given cause in the RRC setup can later result in a packet call setup, if the RRC connection is kept alive. Here, it is considered that only clear indications for the following packet calls can be used. Therefore, 'interactive' and 'background' causes have been selected for the RRC part of Packet Call CSSR formulas.

After the RRC Connection (and the RL) are established, the RAN Services (RAB and RB) are still missing from a complete call setup. Some extra definitions are also needed for the call types Streaming ‘Call’ and Packet 'Call'.

WCDMA RAN Key Performance Indicators

Introduction to WCDMA RAN Key Performance Indicators

The reason for this is that even if the RAB Services and the RB Services are initiated through the defined Access Stratum SAP (defined in 3GPP UTRAN specifications about UTRAN) with RANAP: RAB ASSIGNMENT REQUEST or RANAP: RELOCATION REQUEST procedure, it is possible that the RB Service is not needed at this phase. (The used Iu procedure is defined in the 3GPP specifications on the UTRAN Iu interface RANAP signalling, and RANAP is defined in the 3GPP specifications on Radio Interface Protocol architecture). In other words, there is no data to transmit/receive. So, the RB is set up with any traffic carrying capability. Therefore, for Streaming ‘Calls’ and Packet 'Calls' you – in principle - should not follow the service setup in the CSSR KPIs, but the Packet session setup success rates (SSSR) for Streaming and Packet (packet session is defined in 3GPP specifications about radio transmission technologies). When the session is set up, it means that there is data to be received or to be sent. The packet session setup is here considered to be the point when the reservation of a transport channel starts. The available transport channels are defined in the 3GPP specifications about Radio Interface Protocol architecture. This document gives both CSSR KPIs for all call/service types and a common SSSR KPI for all sessions combined. When needed the reporting tools can produce separate SSSR KPIs for each ‘call’ type.

g

In multi-vendor networks, some vendors do not use the Source Descriptor Voice parameter. Other radio access bearer (RAB) parameters, such as bit rate, can be used to distinguish if the conversational class is Voice. The basic structure of the proposed CSSR KPIs per call type is as follows: 1. AMR CSSR: (Successful RRC setups (MOC Conversational + MTC Conversational + Emergency Call) * Successful RAB setups for Conversational with Source Descriptor = Voice) / (All RRC setup attempts (MOC Conversational + MTC Conversational + Emergency Call) * All RAB setup attempts for Conversational with Source Descriptor = Voice)

1.2.3 Call Success Rates (CSR) in NSN-based WCDMA RAN A call is released by the CN with either RANAP:RAB ASSIGNMENT REQUEST or RANAP: IU RELEASE COMMAND (defined in 3GPP specifications about UTRAN Iu interface RANAP signalling). The release can be a normal release or a drop. A call is dropped if one (or more) of the needed parts, such as RAB, RB or RL drops. When we build up CSR KPIs, the following must to be considered: • •

The Packet Call drop is different than the other call type drops. The difference between a normal call release and drop is not always clear.

First of all, the RAB(s), RB and RL for AMR, UDI and Streaming Call calls are so closely tied together that it can be said that if one of these drops, it is visible as a drop in the other two parts. You can quite safely say that all AMR, UDI or Streaming Call drops can be seen directly by the RAB service drop. Again, for the Packet 'Call', note that the RAB service can still exist even if the RB and/or RL drops. Therefore, you should follow the Packet Session as the key point for Packet 'call' drops similarly to the CSSRs. This document gives both CSR KPIs for all call/service types and a common SSR KPI for all sessions combined. When needed the reporting tools can produce separate SSR KPIs for each ‘call’ type. The basic structure of the proposed CSR KPIs per call type is as follows: 1. AMR CSR: 100 - (Abnormal RAB releases for Conversational with Source Descriptor = Voice / All RAB releases for Conversational with Source Descriptor = Voice) 2. UDI CSR: 100 - (Abnormal RAB releases for Conversational with Source Descriptor = Unknown / All RAB releases for Conversational with Source Descriptor = Unknown) 3. Streaming Call CSR: 100 - (Abnormal RAB releases for Streaming / All RAB releases for Streaming) 4. Packet 'Call' CSR: 100 – (Abnormal Packet Service releases for Interactive or Background traffic / All Packet Service releases for Interactive or Background traffic) 5.

WCDMA RAN Key Performance Indicators

Introduction to WCDMA RAN Key Performance Indicators

For typical values for WCDMA RAN KPIs, see Available WCDMA RAN key performance indicators.

1.3 Resource usage in NSN-based WCDMA RAN The basic setup and release of a 'call' from the perspective of WCDMA RAN implemented by NSN was covered in Calls in WCDMA RAN. This helps with defining meaningful 'call'-based setup success and release KPIs. As pointed out earlier, the 3GPP specifications are rather vague in regard to establishing, maintaining and releasing the related service(s) – the WCDMA RAN-related Bearer services illustrated by the figure QoS architecture - for the ‘calls’. This means that there are (usually) multiple possibilities for handling resources inside a 'call'. The main issues related to WCDMA RAN resource reservation for different Bearer services are summarized here. They are followed up with the given KPIs later in the document.

1.3.1 Principles for resource reservation related to services Generally speaking there are both similarities and differences in the resource reservation between different requested WCDMA RAN services. The similarities are related to the way the needed resources are established, maintained and released. Usually the same external and internal procedures are utilized. The differences are related to the nature of the needed service. RT services constantly need resources (bandwidth) whereas the NRT services do not need resources all the time.

RT Services vs. needed Resources The RT service resources discussed in the KPIs can be related to establishing, maintaining and/or releasing the entire RAB or the ‘Packet Session’, that is, HSPA (HSDSCH or E-DCH) or R99 (DCH) transport channels for the RB.

g

Currently it is not possible to establish ‘Packet Sessions’ for Conversational Traffic Class (‘Speech’ or ‘UDI’) RABs.

NRT Services vs. needed Resources The NRT service resources discussed in the KPIs can be related to establishing, maintaining and/or releasing the entire RAB or the ‘Packet Session’, that is, HSPA (HSDSCH or E-DCH) or R99 (DCH) transport channels for the RB.

1.3.2 RAB Setup and Access Complete Rates The KPIs defined in this document cover the needed reservation procedures of Uu (radio) interface, Access Point (for example, power), BTS function (for example, Channel Elements) and RNC function (for example, Iu user plane) resources.

In this chapter a KPI leveling view is created in relation to the UMTS and QoS architectures presented earlier. KPI leveling is needed to quickly see the relevant (most important) network levels for KPI follow-up.

1.4.1 Principles of using defined UMTS architecture The defined UMTS architecture for Access Network Domain includes external interfaces towards both Mobile Equipment Domain (part of user Equipment Domain) and Serving Network Domain (part of Infrastructure Domain as well as the Access Network Domain). The interface towards Mobile Equipment Domain is called Uu and the interface towards Serving Network Domain is called Iu. Inside the RAN there is an RNC function that has internal interfaces related to capacity reservation towards the external domain interfaces. The transport resources (ATM or IP) are not managed directly by the RNC function. Instead they are managed by the Transport resource manager (TRM). Finally, there is the UTRAN Access point (WCELL) for managing the Radio Link between the UE and UTRAN. The following are the used KPI leveling principles based on UMTS Architecture view: • • •

• •

If both of the external interfaces - Uu and Iu -are related to the defined KPI then it is on the highest level from the UMTS architecture perspective. If either of the external interfaces - Uu or Iu - are related to the defined KPI then it is on the second level from the UMTS architecture perspective. When dealing with RNC function-managed internal interfaces towards either one of the external interfaces, the defined KPI is on the third level from the UMTS architecture perspective. The TRM-related KPIs are found on the fourth level from the UMTS architecture perspective. Finally, the UTRAN Access Point (WCELL)-related issues are on the fifth level from the UMTS architecture perspective.

1.4.2 Principles of using defined QoS architecture The needed KPI levels from the UMTS architecture perspective were listed in the previous section. The QoS architecture only provides additional details to the needed KPI levels.

1.4.3 Access network level KPIs The defined access network level-KPIs in this document cover the external interfaces of the access network towards either the Uu or Iu interface or both interfaces.

UMTS architecture view: When the KPIs of this level are used, they follow up actions of interest between the Mobile Equipment Domain and/or the Service Network Domain from the perspective of the Access Network Domain. QoS architecture view: When the KPIs of this level are used, they give success rates related to 'call' and LCS services. ‘Calls’ are visible in the defined bearer architecture but the LCS utilizes the control plane. Thus, it is not visible in the bearer architecture. Furthermore, the KPIs of this level provide additional success rates related to UE network connection, Radio Access Bearer Service(s), incoming Serving Radio Network subsystem change (SRNS) and outgoing Hard Handovers to either another SRNS (IntraSystem or Inter-Frequency HHO) or other radio access system (Inter-System HHO).

1.5 System Program Report All KPIs defined in this document are important basic network level KPIs for a WCDMA RAN network. In addition to the KPIs defined in this document there are also various KPIs needed for additional purposes found in different reporting tools. When extensive (daily or weekly) follow-up is needed, the number of KPIs needs to be reduced. For this purpose a System Program report is created on basis of the WCDMA RAN release.

1.5.1 Principles of System Program Report The System Program report follows the same structures (KPI levels and KPI classes) as used elsewhere in this document. All KPIs of the access network level are part of the report. Only some of the defined KPIs from the other KPI levels are needed for the report. For the KPIs related to the System Program Report, typical measured values are given when available. The value is either based on the measured performance in the live network or the maximum receivable values measured in a laboratory environment.

1.5.2 System Program Report content The performance targets given in the following table are the average targets for a cell cluster. Performance of an individual cell may differ from the given values.

g g g

Changes in measurements, calculation formulas, and/or used counters affect the listed key performance indicator (KPI) values. The specified targets are not accurate if the load in the network is too low. The load in the network is too low if the average number of calls per cell is lower than (x) during a busy hour. The specified targets are not accurate if the load in the network is higher than the planned target load of the network, or if the actual traffic mix differs considerably from the plan. The following table lists the KPIs that are related to System Program Report according to agreed classification.

WCDMA RAN Key Performance Indicators

3 Available WCDMA RAN key performance indicators This section contains a summary of the current understanding of KPIs to be followed in 3G radio access networks. The KPI development work is always ongoing, and therefore the provided formulas and their typical values are updated frequently. Network acceptance targets are not covered here. If a KPI described here is also part of an acceptance agreement, the acceptance target for the KPI depends on the acceptance agreement. Previously, a target value or a reference was available for all documented KPIs. The approach has now changed. For information on any typical values or references, see the KPIs in System Program Report. In the following table you can see all the key performance indicators in WCDMA RAN. In the table, the following information is given: • • • • • •

Note

Note 1: The Real Time and Non Real Time Inter System HO differs in nature. Therefore the ISHO KPI is splitted in RT and NRT parts. Note 2: The Multi RAB ISHOs are only updated to RT counters. This because the NRT RB follows the RT parameters when part of RT + NRT Multi RAB.

Description

Inter System Non Real Time User Hard Handover Success Ratio [%] from WCDMA->GSM for the reporting period in the Source Cell of the Hard Handover.

Note

Note 1: The Real Time and Non Real Time Inter System HO differs in nature. Therefore the ISHO KPI is splitted in RT and NRT parts. Note 2: The Multi RAB ISHOs are only updated to RT counters. This because the NRT RB follows the RT parameters when part of RT + NRT Multi RAB.
