    4 Performance data management

    4.1 IntroductionPerformance data refers to statistics about network performance, for example, Radio Access Bearer (RAB) setup attempts. The data is presented as counters or performance indicators that are grouped into administrative entities called measurements.

    Performance data management includes collecting, transferring, storing, and to some extent, processing of measurements. This is required in order to make the data available for the various end-user tools for different purposes.

    The statistics are generated by data producers that are distributed across the network. RAN performance management covers the following:

    RNC statistics BTS statistics AXC statisticsThe data, produced in different places and in various formats, is stored and consolidated in NetAct for network-wide use and availability.

    The actual data contents are described in RNC Counters RNW Part, RNC Counters Transport and HW Part, WBTS Counters, and AXC Counters.

    4.2 Performance dataPerformance data is provided periodically as statistics about network performance. This data is collected in counters, which are grouped into measurements for administration purposes.

    The following table describes the most important terms used here and in 3GPP docu-mentation.

    Measurement data are provided for the following two major areas:

    Radio network measurements Transport and Hardware measurements

    4.2.1 Radio network measurement data provided by RNCRadio network measurements by the RNC provide statistical information on the quality of service (QoS), resource usage, radio connection, mobility, and signaling events within the radio network.

    Radio network measurements are listed in the pyramid of the following figure. For more detailed measurement and counter information, see RNC Counters RNW Part.

    g The mcRNC provides the same radio network measurements as the IPA-RNC.

    Figure 3 Radio network measurements provided by RNC

    4.2.2 Transport and HW measurement data provided by IPA-RNCThe IPA-RNC Transport and HW measurements provide statistical information on trans-port network signaling, ATM/IP transport, DSP resources, transport network L1 trans-mission, and RNC computer units.

    Measurements that describe the transport network and the RNC computer unit perfor-mance are listed in the pyramid of the following figure. For more detailed measurement and counter information, see RNC Counters Transport and HW Part.

    All the newly added/deleted RNC transport objects are updated dynamically in the measured object list. This function is activated if the ALL-objects parameter was set in the measurement administration.

    Performance data management

    4.3 Data collectionMost of the statistics from the whole network can be collected in the NetAct. The RNC PM data is mediated by the Operation and Maintenance Server (OMS). The RNC collects the data from internal data producers and the OMS prepares it for transfer to the NetAct.

    The data transfer interface between the OMS and the NetAct uses measurement data files, notifications, and scheduled file queries. The primary method for collecting RNC data is based on a notification mechanism. The OMS notifies NetAct about the data ready to be transferred, then the NetAct handles the actual transfer and, for example, the related acknowledgements and transfer state.

    The interface includes various recovery mechanisms. There is also a scheduled file query that ensures the proper transfer of all data, even if the notifications are temporarily blocked, for example, due to software upgrades.

    The BTS data is also mediated through the OMS in a similar manner, but AXCs are handled as separate entities, because of the interfaces and their role in the network. NetAct has a direct PM data collection interface towards the AXCs, and the data collec-tion is always initiated by the NetAct. NetAct supports collection of measurements from a predefined set of counters from the AXCs, from a limited area or number of network elements.

    4.4 Data storage and usageThe main data storage is in the NetAct, which provides a network-wide view of the sta-tistics. There are several options for storing the data. Typically, the data is stored as such for a relatively short period, for example, for a week or two. It can also be aggre-gated over time or network dimensions, for example, to get daily or network element level values, and kept for longer periods to provide historical and trend data. There are different data warehousing capabilities depending on the system configuration.

    The storage provides a consolidated view over the whole network or cluster, depending on the configuration, and the data can be used with various NetAct tools. Some of them also provide some intelligence for combining data of various types, including, for example, the configuration parameters. PM data can also be exported to third party systems via the measurement data export function. For comprehensive details on the function available via the NetAct, see NetAct product documentation for Reporting, Mon-itoring and Optimization Functionality.

    Data is also stored in the OMS for short periods for NE-level usage. It can be used with local element management applications for simple reporting or troubleshooting. Data is also used for specific applications like threshold monitoring, but there are no options for exporting it to any third party system from the OMS.

    To show the measurement results in graphical and textual format, use the RNW Mea-surement Presentation GUI.

    For more information on measurement presentation, see Managing and Viewing RNC measurements.

    The BTS and the AXC also provide a short-term local view of the data. This can be used only through element manager applications.

    4.5 Alarms for PM data transfer failuresIt is crucial for the data users that the statistics data flow is reliable. There are many in-built mechanisms for automatic recovery from problems without unnecessary user action or loss of data, but it is inevitable that problems will sometimes occur.

    The PM architecture is based on several distributed entities communicating over a data communication network of variable quality. There are several ways to detect general problems in the data pipe, such as DCN connection breaks, but PM-specific indicators are available as well. These specific alarms are meant to complement the generic notices, and are only generated for situations that:

    result in loss of data require explicit action for resolution indicate a problem in the performance of measurement data processing or transferMore specifically, they are introduced for the following failure situations:

    The OMS is not able to retrieve measurement data from the RNC Operation and Maintenance Unit (OMU) or the BTS.

    NetAct is not able to retrieve measurement data from the OMS. There are problems in measurement data processing.Alarms are cancelled after the situation has recovered.

    Measurement administration

    5 Measurement administrationPerformance management includes functions for administering the measurement data collection. With these functions, it is possible to define the schedule, interval, and the collection of desired measurements for most of the different statistics.

    Schedule refers to settings that determine the planned time of data collection. Interval is used to set the measurement granularity, for example, 60 minutes.

    5.1 Centralised measurement administrationNetAct provides centralized management for the AXC, BTS, and RNC RNW measure-ments that form the majority of the statistics in the RAN. The function is based on a mea-surement plan concept. It is possible to create plans with the desired settings, and to activate them on the selected network elements without configuring each element and measurement separately.

    Measurement plan activationActor: Measurement Administrator

    Tool: NetAct Administration of Measurements application

    Frequency: Seldom

    1. The user creates a plan that includes the required measurements and settings.2. The user selects the network elements for the plan activation.3. NetAct activates the plan on the selected network elements.After the measurements are activated, NetAct receives data from the selected statistics. The plan and measurements are active for the relevant network elements.

    The RCPM raw measurements are exceptions, as they include special parameter set-tings, or are only intended for monitoring limited area or connection types at a time. These and the IPA-based statistics for RNC transport and platform must be adminis-tered on a network element basis with the Element Manager at O&M mediator.

    RCPM pre-aggregated measurements can be managed with NetAct.

    BTS and AXC measurements always use a predefined interval, so that setting is not relevant for them.

    5.2 Local measurement administrationIt is also possible to use the local element manager function for administering RNC RNW measurements. The centralized management application is also notified if there are local modifications to the measurement settings.

    Local administration and measurement administration notificationsActor: Measurement Administrator

    Tools: Element Manager at O&M mediator, NetAct Administration of Measure-ments application

    1. The user changes some measurement settings locally with element manager.2. The network element sends a notification about the change to the NetAct.

    Collection of key counters

    6 Collection of key countersNetAct provides a separate key counter measurement, which can include a collection of priority counters from the cell-level measurements produced by the RNC. The data is accessible through NetAct tools and interfaces, in the same way as other PM data.

    Once installed and activated, the feature can be used via the normal PM data collection and activation mechanisms.

    Key counter measurement provides an opportunity to save capacity in the network man-agement systems. The source measurements can be collected in parallel with the key counter measurement, but the measurement interval for the new measurement can be set to be different. This enables the key counter measurement to collect some of the data more frequently, without compromising too much on the system capacity by collect-ing everything at the finest granularity. The new measurement can be collected, for example, at 15-minute intervals, while keeping the source measurements at 60 minutes.

    There can only be one key counter measurement, and its definition must be consistent across all the RNCs in the network.

    There are some specific constraints that apply to the usage and settings of the measure-ment:

    The supported intervals are 15, 30, and 60 minutes. In addition, the interval must be shorter than, or equal to the interval of the source measurements on which the key counters are based. The maximum interval for a source measurement is 60 minutes.

    The key counter measurement contains 500 counters, which must be from the cell-level measurements that are produced by the RNC.

    The key counter measurement is only available from the NetAct, but it can be forwarded through the export interface towards other management systems.

    WCDMA RAN Performance Management Key performance indicators

    Id:0900d8058081f485Confidential

    7 Key performance indicatorsThe Key Performance Indicator (KPI) is a function of performance measurements. In its simplest form, a KPI is an individual counter, but usually it is a calculation formula made of several counters.

    With carefully defined KPIs, the operator can easily see the overall status of the network performance, for example, if the RRC or RAB setup success ratio is as expected, if the RAB drop ratio is at an acceptable level, or if there are severe problems with the handover success ratio.

    There are different kinds of KPIs:

    official RAN KPIs (as defined in RAN documentation) other Nokia Siemens Networks-defined KPIs (as defined by NetAct documentation) user-defined KPIs

    7.1 KPI calculationKPI calculation can be carried out in O&M mediator, NetAct, and 3rd party tools. This description focuses on KPI calculation carried out in the O&M mediator.

    The operator can view the RNC KPIs through the O&M mediator. The KPIs can be viewed through the RNW Measurement Presentation GUI.

    The operator can use predefined KPIs (a subset of RAN KPIs) or define their own cus-tomized KPI formulas. The operator can create and modify their own KPIs through the NE Threshold Management GUI (part of the O&M mediator).

    Figure 6 KPI calculation in the O&M mediator.

    By using the tools available in the O&M mediator, the user can analyze in detail the mea-surement data related to a specific area of interest. This is also useful if the operator does not want to transfer all measurement data up to NetAct (for example, for capacity reasons).

    NetAct tools can be used to get an overall picture of network performance, and O&M mediator tools can be used to see deeper into the network element, for example, for troubleshooting.

    WCDMA RAN Performance Management Threshold monitoring

    Id:0900d80580820025Confidential

    8 Threshold monitoringPerformance statistics can often indicate a problem or a noteworthy event in the network or service functionality. The OMS provides an automated means to analyze RNC-level statistics as they are collected. This makes it possible to raise an alarm or notification based on predefined thresholds, as soon as the statistics are available in the O&M medi-ator. Threshold alarms are handled in the same way as any other fault management (FM) data, so they can be monitored with the common FM tools.

    The O&M mediator element manager provides a tool for creating and managing thresh-old rules. Performance thresholds can be set for the variables, such that exceeding them indicates a problem worthy of attention. The variables can be either single counters or KPIs, which can be calculated from several counters using a user-defined formula. It is also possible to export the definitions and apply them to the other RNCs as well, without a need to create all the rules separately for each element.

    The threshold rules and related measurements must be explicitly activated before they are in effect. After that, the OMS evaluates data against the rules and generates alarms accordingly. The alarm contains some basic information, but the details are also stored in the OMS for further study. The alarm information is processed further, as described in the fault management documentation.
