Overview
As the communication world transforms to a service-oriented system, the next generation operators have to deal with multi-technology, multi-vendor networks. The operators not only have to provide a varied set of services to their customers but also need to contend with the pressure on the networking resources as the services multiply. In such a scenario, it is essential that the operator has a consistent view of the performance and utilization of the entire network. Only then can the operator efficiently utilize and plan the network resources available. The performance and maximum utilization of the network is not the only challenge for operators. Next-generation architectures and service delivery platforms will enable them to deliver highly personalized services to their customers. To successfully deliver this kind of services it is required to correlate network information up to the customer level. Combining customer-specific information with relevant operations data such as information from the billing, customer care, and performance data from the network will enable the operator to achieve a complete view of each customer and his or her value. This information on network performance and resource utilization is continuously produced at different points and different abstractions of management (Element level, Network level, Service level, etc.). In the real world’s complex systems, the amount of Performance data that can be produced is huge, but not everything is required at the time. Performance Management tools have to provide then the means to collect the required data timely and on demand and be able to provide the users and the organization processes with specific information to fulfill the described management needs of the operators.

Performance Management Principles
1.3
Performance Management Process
The performance management process comprises the description of a view on the PM tasks the operators follow in order to monitor, assess the quality of the network and obtain the requested output information for the different users and processes inside the operator’s organization.
1.3.1
Defining or revising Quality of Service goals
When managing a particular network, the Quality of Service (QoS) represents the effective maintenance state of the quality for the network services according to some agreed criteria. Maintaining and improving the QoS of the network includes regular monitoring of the service performance and the evaluation of the service performance problems with respect to the targeted level of service delivery. To improve the service, it is necessary to define QoS goals that guide the evaluation of network and service performance. These goals can represent, for example, the point of view of the operator (efficient hardware usage, for example efficient use of network elements considering the type and capacity of the NEs, their location and number to support the services) or the point of view of the subscriber (availability, speed, and accuracy of the service). As the network evolves and expands, these QoS goals might have to be updated and revised. Mature operators competing for more market share benefit from introducing new services to differentiate themselves from other service providers. At this point, all kinds of service and profile measurements are useful. The quality of service becomes extremely important and, for example, optimization measurements must be taken. The following tasks belong to this stage: • Setting objectives for the desired level of quality • Measuring the quality of service by monitoring real-time data and long-term trends • Planning corrective actions
1.3.2
Translating Quality of Service goals to network performance requirements
To achieve the defined QoS goals, it is necessary to prepare or update the detailed requirements for the network, including the requirements on network performance. For example, the quality of a voice service can be correlated with the number and ratio of dropped calls, while the accuracy of an IP service can be correlated with the number of received packets.

Performance Management Principles
1.3.3
Defining reporting requirements
The network performance requirements serve as the basis for reporting requirements and provide information on which measurements you have to monitor with the PM applications.
1.3.4
Identifying other reporting needs
Monitoring the day-to-day performance of the network is not the only reason for using performance reports. Information from reports can be used, for example, to examine shortterm changes due to system upgrades or to revise long-term trends to gather information for optimizing or expanding the existing network. If these reporting needs are translated into measurements, the reporting requirements are then clear and can be translated into measurement activation criteria. However, some reporting requirements can give rise to a need for a new or an additional PM application. You might also need a new or additional PM report when you are investigating uncommon situations or when you have upgraded or expanded your network. Before establishing new reports, it is recommended that you check whether the active measurements already provide the counter information that you need, or whether the required measurements are available but have not been activated yet, or whether it is sufficient to change the measurement settings to obtain the needed information.
1.3.5
Defining reports
You can define and schedule your reports based on the reporting requirements. The details of defining reports mostly depend on the OSS solution.
1.3.6
Adapting the measurement load and the OSS
If you need a new measurement, you have to ensure that the capacity of the OSS, for example, disk space and insertion time, is not exceeded when the new measurement is implemented and activated. If the OSS capacity could be exceeded, you can adapt the entire measurement set by reducing the number of the measurements or increase the measurement intervals, or you can increase the OSS capacity, for example, with additional processors. If the capacity has not been exceeded, you can proceed with initializing the additional measurements.

Performance Management Principles
1.3.7
Initializing measurements
Activating all the necessary measurements across the network could impose a significant but unnecessary load on the database and the PM processes. So, it is recommended to consider the following factors: Period when measurements are active in the network element or the measurement information is uploaded from the network element to the network management system Measurement intervals Number and distribution of the network elements for which the measurement is activated
1.3.8
Defining thresholds
Network management systems allow you to define thresholds for the measurements. When a measurement value exceeds a threshold, an alarm is raised. So, you can follow the status of network performance with the fault management applications in which the alarm is visible and also with the performance management applications in which the measurement information is processed. The details of defining thresholds mostly depend on the Operations Support System (OSS) solution.
1.3.9
Collecting data
The measurement information can be preprocessed in the network element, depending on the NE type and the configuration of the NE. If preprocessing is applied, the data is filtered, that is, not all of the measurement information is forwarded to the network management system) or some calculation is done on the measurement data before it is uploaded to the OSS through the NE-specific interface. The data can also undergo further processing in a post-processing phase, for example, when busy hour information is needed for a report. The results of the post-processing are also stored in the OSS database. The data is used by the reporting applications or is exported through the open interfaces to external systems.
1.3.10
Monitoring network performance
You can typically find performance-related problems by checking the alarms, the measurements, and the customer complaint reports. You also can use information from drive tests and call detail reports (CDRs). Regular reporting such as running a report once a day or once a week is too slow for continuous network monitoring. Furthermore, the default measurement interval for most counters, one hour, may create a huge delay. However, you can also analyze the traffic statistics and collect detailed information from the network for further analysis with reports when you discover a problem. Prompt reaction is sometimes required. So, it is recommended that you set thresholds for the performance indicators so that the OSS raises alarms based on the indicator values in unusual situations or when errors occur.

Performance Management Principles
1.3.11
Generating and distributing reports
When you defined the reporting requirements, you also gathered information on the user groups and on the types and frequency of the reports that they need. You have to ensure that the users of the OSS have access to or receive the reports that best support their work. Reporter applications allow you to turn the often overwhelming amount of measurement data into information on the performance of the resources in your network, which you can use for determining whether the network performance goals are met and whether problemdetermination procedures should be initiated based on performance.
1.3.12
Analyzing the results
PM reports are mostly used for two purposes: to gather information for troubleshooting (short-term reports and ad-hoc reports), for prevention, and for developing the network and the services (longer-term reports). For example, the top management of an operator can use PM reports for obtaining high level information on the network operation at a glance. It is possible to use a report about the length of the calls to determine whether the service is becoming more or less popular among the subscribers and in what times of the day subscribers use particular services the most. The call durations plotted against the day gives information on the preferences of the subscribers and helps you decide about marketing campaigns, special rates for busy hours or off-peak hours. You can also monitor whether a network expansion has the expected results on the quality of services by regularly checking your own customized reports. With regular checks you can avoid significant negative impact by taking corrective actions as soon as deviations are observed in the quality of the service. When you have to optimize your network or when you consider an expansion, you can use various PM reports to gather information on the past. You can also use the reports for monitoring the network performance over a certain period of time and check how the QoS and other quality objectives are met and identify possible problem areas in the network. For optimization, for example, you might need detailed quality information on particular measurements in a particular BSS. For expansion and planning, you might need a less detailed report but over a longer period of time to observe trends in the subscriber behavior or network resource usage.

Performance Management Principles
1.4
Performance Management Applications
Depending on how the performance management applications use the collected data, they can be divided into two main types: performance monitoring and performance reporting applications. Performance monitoring is online-oriented and provides you with relatively real-time information on the network. Therefore, performance monitoring applications generally use shorter measurement output intervals because faster reaction is needed in severe problem cases, in which a 24-hour interval would be too long. The outputs of performance monitoring applications are mainly used as additional information for problem cases in which no alarm information is available. Performance monitoring rules are intelligent threshold rules and can be calculated before or after the measurements are stored in the database. Performance reporting is offline-oriented and provides information on what happened in the network over a certain period of time. Performance reporting applications mainly rely on performance indicators and produce reports, which you can use, for example, when you are troubleshooting, planning, or optimizing the network

Performance Management Principles
1.5
Using Performance Information
The operator organization can use the various types of performance information for monitoring and managing the network. When monitoring a network performance, different types of data are collected in order to locate potential problems as early as possible and to verify the physical and logical configuration of the network. The performance data can also be used to monitor subscriber behavior by charting out the usage of different services that are available to the end-users. Such information provides the operator with input for business and service management decisions when you are optimizing and expanding the network. Performance-related information in the network is of vital importance for taking management decisions and identifying possible current or future problems and opportunities.

Performance Management Principles
Using Performance Information Network elements produce data to support performance evaluation, for example on the following areas:
Traffic levels within the PLMN, including the level of both the user traffic and the signalling traffic.
Verification of the network configuration.
Resource access measurements. Quality of Service (QoS) Resource availability.

Reporting Needs
Networks continuously produce an enormous amount of performance data. PM applications need to filter the information to suit the needs of various users: Management and operational levels at the operator. Technical considerations in the network, for example monitoring the radio access and the core network separately. End-user perception of the services about traffic, quality, or availability of the services. The following figure shows reporting needs in a combined model. Each chunk of the pyramid corresponds to a report set or report group that PM applications can provide to the various user groups. The applications allow you to turn the often overwhelming amount of measurement data into information on the performance of the resources in your network, which you can use for determining whether the network performance goals are met and whether problemdetermination procedures should be initiated based on performance. Various user groups can use performance measurement data for managing the network and what kind of PM applications they can use depend on the objectives.

Main Concepts for Performance Management Counters, Measurements and Observations
A counter is a register which is updated in the NE each time an event occurs. There are different types of counters based on how they can be updated. Cumulative counters represent a running count of, for example, how many times an event occurred while gauge counters take the value of what they measure, for example how many data packets are in a buffer. When a measurement interval ends, the values of the measurement counters are transferred to the OSS and the counters are reset for the next period. A counter provides the result in specified units, for example, in integers or Erlangs. The term counter is used as a synonym of Performance Indicator. A measurement is an action where the system collects information about e.g. traffic and network events and then processes this information. A measurement is a fixed set of counters. An observation is a function where the system either collects information about certain events or directly produces information about single events in the system. It is possible to set certain objects under observation and to set conditions which must be fulfilled before the system produces reports or alarms Observations are typically used to locate the part of the network system causing problems. A measurement is in fact a collection of statistics, or to be more precise, a collection of counters. All of these counters are counting a particular event that relates to the measurement name. The measurements are grouped in this manner to allow better functionality and handling. This provides the user with easier selection of certain measurements necessary at a particular time. All measurements are independent of each other but the same user interface is used for handling all measurements. Each network element can have only one instance of each measurement running. In other words, the measurement is either active or not. Each measurement has a reporting period, therefore at set intervals, each counter will return with a value for each object. The output interval determines for how long counters are collected into a measurement. Measurements can be collected at regular intervals: 15 - 30 - 60 minutes, 2 - 3 - 4 - 6 - 12 24 hours.

Logical Counters and KPIs
A Logical Counter is a formula which combines, with arithmetical operations, data collected from measurement counters. Logical Counters that describe the most important aspects of the network operations are referred to as Key Performance Indicators (KPIs). A KPI can also include counters from different measurements. The measurements/counters must, however, all be of the same object level for you to be able to include them in one KPI. The operators decide individually what the KPIs are when they define the contents of the reports

Performance Management Principles
1.7.3
Key Performance Indicators and Reports
Network performance can be evaluated based on key performance indicators (KPI). The users finally decide what key performance indicators are used when they define the contents of the reports. Key performance indicators use the counters received from one or various measurements. To create formulas, all the measurements used in the formula must be activated, and in addition, the measurements have to have the same output intervals. In case the measurements have different intervals, the measurements can be examined only according to the longer intervals. For example: Data is received from two NEs. The interval for one NE is set to be 15 minutes and the interval for the other NE is one hour. The KPI values can then be examined only with the minimum time period of one hour.

Types of Reports
NSN recommends the following analysis process while producing three different kind of reports: Profile (trend) reports show the pattern of studied KPIs for a longer period of time. In profile reports, the focus should not be in exact numbers but in the shape of the trend line. For the operators it is very essential that the performance of the network can be followed during a longer time period and whether or not network performance has enhanced during this period. Reporting Suite show detailed information of the KPI. Top-N reports illustrate those N objects among all the studied ones that have the highest or smallest value with respect to the sorting measurement counter. Running Top-N reports illustrate the most troublesome managed objects that should be studied in more details or the ones having the biggest amount of traffic in Erlangs.

Post - Processing of Measurement Data
The post processing on Measurement data is executed in the OSS level. The Reporter processes in NetAct post-processing to enhance the performance of the Reporter processes. NetAct supports aggregation: to speed up data processing to allow flexible report generation from the measurement data to avoid database overload by storing raw data for only a short time (configurable) Measurement data can be aggregated along a dimension that this specific measurement supports. Reporter stores the data that is aggregated per counter in summary tables. Four types of aggregation are available in NetAct: the aggregation can take the lowest value (MIN), the highest value (MAX), the sum (SUM), or the average (AVE) of the counter values at the aggregation level. For information on the aggregation for the counters, use Adaptation Information Browser (AIB) application (more details in chapter two of this course) The following examples show typical aggregation dimensions with their aggregation levels: time: hour, day, week, busy hour, and weekly busy hour object: cell, BSC, and network drop reason: LAPD failure, network failure, and all One special case for aggregation is the calculation of busy hour. This aggregation method is applied to certain measurements during which the busiest hour of a day or week is taken into account. The weekly busy hour is calculated as the busiest hour of the week. Daily aggregation starts at midnight and weekly aggregation starts on Monday morning. The measurement types are aggregated separately. The aggregation processes are configured and executed separately per each adaptation.

Aggregation Examples
NetAct receives raw data from NE Let's assume that the NE sends two measurement types: "Blue" with 5 counters (hourly) "Yellow" with 10 counters (daily) After each measurement period, the measurement values are sent to NetAct: "Blue" with a measurement period of one hour, "Yellow" with a measurement period of one day. These counters are the raw data.

Performance Management Principles
Daily Aggregations (time) NetAct aggregates each measurement type separately: the hourly measurement (Blue) is aggregated into daily measurment accordingly with the aggregation rules for each of its counters. The daily measurement (Yellow) is not processed for daily aggregation as its measurement period is already daily.

Weekly and Busy Hour Aggregations (time) NetAct aggregates each measurement type separately. In the weekly aggregation case, the daily already aggregated measurement (Blue) is aggregated into a weekly measurement accordingly with the aggregation rules for each of its counters. The daily measurement (Yellow) is now aggregated into a weekly measurement accordingly with the aggregation rules of its counters. The busy hour is an aggregation method for certain measurements during which the busiest hour of a day or week is taken into account. The weekly busy hour is calculated as the busiest hour of the week.

Performance Management with NetAct
Networks continuously produce an enormous amount of data on areas like traffic level, network configuration, resource availability, resource access, or quality of service. These data need to be consolidated and translated into meaningful reports in order to monitor network resources, verify physical and logical configurations or identify problems as early as possible. With NetAct Reporter operators can consolidate their performance management work flows, simplify user processes and automate tasks. NetAct Reporter is a comprehensive end-to-end tool for network-wide reporting. It enables the collection of raw and aggregated data as well as the compilation and visualization of reports on, for example, network and service performance, usage, quality, and history. The collected data can be stored in separate databases for either short-term reporting or long-term analyses. In addition, it is possible to export the raw data to higher level systems via a file-based (XML formatted) interface The Reporting functionality is responsible of collecting, post-processing, storing, viewing, and analyzing information about the performance and quality of the network. It gives a networkwide view of network and service performance. With Reporting you can analyze network data, create reports based on that data, and distribute the information within the organization.

Administration of Measurements
The Administration of Measurements is the NetAct solution for activating and deactivating measurements in the Network Elements remotely from the network management system. Before data can be inserted into the NetAct database, it is required to activate measurements in the network elements. Measurements can be locally activated with an element manager in the network element directly or centrally with the NetAct application Administration of Measurements. Central measurement administration avoids the inconsistencies that might occur when network elements are administered one-by-one in single operations. The same measurement plan can be activated on all the network elements belonging to the same object class. The Administration of Measurements application provides services to manage measurements, such as creating Measurement Plans to select and schedule measurements and counters in one network element. You can start and stop measurements in one operation for several network elements. With Administration of Measurements, it is not necessary to use commands to start and schedule measurements separately for each element in a network. The reusable Measurement Plans allow systematic and controlled administration of the measurements. Furthermore, the non-manual approach not only reduces the number of errors, but also has cost-saving effects.

Data Collection and Processing
Different performance measurements are combined to adaptations. Typically the measurements from one network technology are bundled in a data module. NetAct Reporter offers the adaptations as part of the common functionality, which can be activated if the appropriate network technology is available. NetAct 7 has adaptations to both network elements which are connected directly NetAct Base and to network elements connected via OSS5.x. Three tasks have to be executed to enable the NetAct Base to receive measurement data of a network element: An adaptation that supports the network element type has been installed in NetAct Base. The physical network element has been integrated into the NetAct, so that performance and alarm data can be exchanged. The network element has been configured to send measurement data, either manually or by using Administration of Measurements. These preparation tasks enable a continuous PM data stream from the network element to the receiving NetAct Base. The received data is transformed to the NetAct Base native PM data format. Required conversion configurations or scripts are part of the respective adaptation. Once measurements are inserted into the NetAct Base database the respective data is available for further reporting and usage.

Data Reliability
The data reliability feature provides important statistical data that allows you to identify if there were gaps in the data flow process. These gaps must be taken into consideration when performing corrective actions, since reports are often used in the decision making process. Knowing the data reliability for a specific report is very important. Each measurement reliability, for each day, is taken in consideration when calculating the report data reliability. Data reliability is not available for transient levels. You must verify the data reliability for the physical level closer to that transient level. For reports using the week aggregation level, the data reliability evaluates the data for the day level, assuming the same data volume for the upper aggregates. If your report time level is set to raw, the data is aggregated in runtime for the day level, and data reliability is calculated for each day. There are three possible states represented by default in red, orange and green colors. You can edit the engine.properties file and change the threshold and color of each state to suit your needs. The data reliability option is available in the Report Output toolbar by clicking the Report Info button and selecting Data Reliability. The Data Reliability window pops-up displaying the report results highlighted with the respective colors defined in the engine.properties. Data Reliability table allows you to perform drills at the object level.

Rehoming
The rehoming support solution in Performance Manager recognizes the relocation of network elements to a different parent in the topology. It processes Configuration Management Data and automatically updates affected reports and summaries. Reporting over rehoming cases is transparent and requires no additional administration effort.
WARNING Some adaptation packages do not support rehoming. Select the check box to enable rehoming. The rehoming switch-over period is shown in charts as if the rehoming has never happened. Chart lines are continuous at rehoming switch-over period. The following figure shows a rehoming event.
In the report output, in the daily time level, the old RNC (dianthus_RNC-92) only displays the information before the rehoming switch-over period, while the new RNC (dianthus_RNC-84) only displays the information after the rehoming switch-over period. In the matrix output at the WBTS or WCEL report level, in the hourly time level, the rehoming information displayed depends on the selected hour. If the hour is earlier than the rehoming switch-over day, only the old RNC information is displayed. If the hour is later than the rehoming switch-over day, only the new RNC information is displayed. If the hour belongs to the rehoming switch-over day, all rehomed instances information is displayed,regardless of the RNC.

Administration of Measurements
The Administration of Measurements is the NetAct solution for activating and deactivating measurements in the Network Elements remotely from the network management system. Before data can be inserted into the NetAct database, it is necessary to activate measurements in the network elements. Measurements can be activated locally with an element manager in the network element or centrally with the NetAct application Administration of Measurements. Central measurement administration avoids the inconsistencies that might occur when network elements are administered one-by-one in single operations. The Administration of Measurements application provides services to manage measurements, such as creating Measurement Plans to select and schedule measurements in one network element. Measurements can be started / stopped in one operation for several network elements. With Administration of Measurements, there is no need to use commands to start and schedule measurements separately for each element in a network. The reusable Measurement Plans allow systematic and controlled administration of the measurements. Furthermore, the non-manual approach not only reduces the number of errors, but also has cost-saving effects. Less disk space is needed since only relevant PM data is stored in the database. Administration of Measurements' graphical user interface contains four tabs: Network Overview: To view the activation status of measurements in the network. Plans: It enables to create, modify, delete, activate and deactivate plans. Templates: To create, modify and delete a template. It also allows creating a plan based on an existing template. Upload Overview: To view a summary of all the upload operations carried out during a specific time period for specific NE Types.

Data Reliability
This report provides status information on the PM tables, depending on the adaptations configurations. Continuous monitoring of the Data Reliability information allows you to identify gaps in the raw data flow. Once you have identified where data is missing from, you can take appropriate corrective actions. The Data Reliability report is available for all network elements that are integrated to the NetAct system and are sending data to NetAct. However, some restrictions apply: • If there is no measurement data available for an adaptation in the NetAct Database, the adaptations and network elements are not visible in the Data Reliability reports • Data Reliability is only available for adaptations that support selective summarization • Reliability information is only provided on the raw data: the report does not check the completeness of the summary tables
15.2.1
Using the Data Reliability report
When you open the report from the Navigation Tree of AdminToolkit, the cluster-level report is automatically displayed. The report always covers the last seven calendar days. If you change the thresholds for the reliability ranges, click Submit Query to display the updated report; You can drill down to the level of PM tables and check the reliability per measurement by clicking in front of the adaptation in the top-level report. You can return from the PM table overview to the adaptation overview (top-level report) by clicking Go Back. Drilling down along the topology dimension provides information on the reliability at the level of measured objects (in the 2G network dimension: BTSs and TRXs).
15.3
Adaptation Configuration
In the Adaptation Configuration section, you can configure the following items: TRACE_LEVEL - Debug trace level for the logs. Range is from 0 to 9. 0 disables tracing PARALLEL_PROCESS_NR - Number of aggregation processes that can run in parallel (110) CAPACITY_LOG_LEVEL - Capacity log level. Range is from 0 to 2. 0 disables capacity logging. To change adaptation configuration: Select the Adaptation. Enter the Value for the Configuration Item you want to change. Click on the Apply button.

PM North Mediation Interface
With the PM North Mediation Interface, you can transfer measurement data to an external system. In OMeS, data export and file transfer are based on an advanced XML format. The main advantages of the interface are: The OMeS file format exported through the interface allows the use of universal tools with XML support. This enables easy and cost effective integration of any third-party system to NetAct. The rule-specific filtering function can avoid transferring irrelevant measurement data to the system. Third-party integrations do not cause extra load on the performance database. The capacity of NetAct is thus ensured in all circumstances. The interface can be configured for multiple independent output pipes according to the possibility to increase or decrease and process resources in the system. The interface can be configured to create hourly subdirectories for each NE type export directory. Possibility to configure the interface to compress exported OMeS files. The figure below shows the measurement data flow in the PM North Mediation Interface: Measurement data export process consists of the following phases: 1. Measurement data is collected from the network elements (NE) to NetAct. 2. Data uploader stores incoming data in the database. It checks if the data export function is activated in the configuration file and then forwards data to the exporter process. The configuration file /etc/opt/nokia/oss/reporter/conf/etlpslmx.cf contains the activation flag EnableDataExport true/false. Note: NetAct inserts the distinguished names (DN) into the output file, but does not manipulate the data of individual counters during export. The exporter process receives data from the upload process and writes it into an output file after filtering.
3. PM North Mediation Interface writes the incoming data to the OMeS formatted XML file according to the rules set in the pipe configuration file, which is located under /etc/opt/nokia/oss/reporter/conf/etlexpmx.pipe. The name of the pipe file can be given freely. But the output directory must be globally reachable in the cluster. The default output directory is /var/opt/nokia/oss/global/etload/work/export.
4. An external system using the data can access the files. The external system is responsible for administering the OMeS files. In particular, the external system using the files has the primary responsibility of deleting the old OMeS files from the directory after processing them (for example, loading the data into a third-party system).
5. NetAct will automatically clean up the files that are older than the storing period configured in the pipe configuration file, by default 1 day. To modify this value, edit the pipe configuration file /etc/opt/nokia/oss/reporter/conf/etlexpmx.pipe. Then send the HUP signal to all exporter processes.

(etlexpmx "" (storingPeriod "7") ...... )
Note: If number of days for cleanup period is mentioned as x, then the files that are older than (x+1)*24 hours are cleaned from directory /var/opt/nokia/oss/global/etload/work/export and any other directory set in the pipe configuration file.For example, if the cleanup period is mentioned as 7 days, files that are older than [(7+1)*24] hours are cleaned.

Overview
Software Asset Monitoring application collects and processes the configuration and measurement data based on customer specific settings. It generates a report on the feature usage and forwards the formatted monitoring data to the customer and NSN Customer Team via an encrypted e-mail. The encrypted e-mail can be read and validated by Customer and NSN Customer Team only. The report on the feature usage is used to generate an invoice. One software monitoring report comprises information related to one NetAct cluster. Note: For LTE and Flexi Direct, software monitoring is the only way of usage control as License Keys are not implemented for these technologies. Software Asset Monitoring enables speed and efficiency with fast software activations through bypassing the pre-activation procurement process, and applying alternative pricing models where invoicing is based on network configuration or on used functionality. This results in OPEX savings and in an increased flexibility. Monitoring data are configuration management (CM) parameters and performance management (PM) counters. Software Asset Monitoring application stores the data for further handling such as pre-processing to make raw monitoring data more accurate and usable, for example, data size is reduced, and data are presented in more convenient way to the user. Local storing of data is needed before andafter data processing. A report is periodically generated based on monitoring data and sent to NSN side where later on it is used for invoicing purposes. Monitoring modules are product specific elements, which allow an incorporation of specific reporting methods. Monitoring modules are divided into two groups, PM and CM, particular for each network technology.
