Nokia Siemens Networks Portfolio
Nokia Siemens Networks has an extensive OSS/BSS product portfolio covering all telecom
domains from element management layers to service and business management. Key
products have been commercially available since 1992, and today over 1.2 billion end-users
enjoy services accessed through networks managed by our network management systems.
To address the challenges service providers are today facing on their local and global
markets, Nokia Siemens Networks is developing and renewing its product portfolio to provide
topical solutions for operator customers. Telecom business transformation shaping many
markets today calls for OSS transformation in a form of a well-designed next-generation OSS.
Nokia Siemens Networks’ new OSS/BSS products with new architecture fulfill the following
expectations:
Ability to support operators’ business processes by introducing modifiable operator process
templates out-of-the-box to enable higher level of automation in many of operators’ daily
routines.
Shared information and data model; enabling OSS/BSS level application interoperability
through Common Information Models.
Modularity of application architecture, allowing flexible building of solutions based on
customer needs. The architecture also provides the openness that allows easy
implementation of additional 3rd party applications on top of the platform.
Separation of the application architecture from network element adaptation/mediation layer.
Thus, the applications should be built as multi-vendor and multi-technology capable by
nature. In practice, this would speed up the rollout of new network elements or
functionalities, as new equipment can be implemented and integrated without major
changes to the OSS application architecture. Similarly, introducing new OSS functionality
can be done independently from managing the network element adaptations.
Common platform for converged OSS solutions, and harmonized software and hardware
assets when building these solutions. This harmonization will reduce operators’ costs on
system administration and maintenance, system integration, training and naturally, on the
initial infrastructure investments.

What is NetAct
NetAct 6 and NetAct 7 are the Nokia Siemens Networks’ network management system
(NMS) family of products, designed for centralized management of multi-vendor and multi-
technology telecommunications networks. Its functionalities include configuring,
administering, monitoring and reporting the network and its operation.
NetAct 6 and NetAct 7 Releases are not an end products by themselves but serve as
foundation for other NSN Network Management products. Provide common functionality that
is used by other higher level products and promotes software re-use. NetAct 6 & 7 bring a
complete new architecture that changes the network and resource centric approach into an
end customer – service oriented OSS/BSS solution.
This modernized OSS architecture provides the following advantages to operators:
Consolidation: A complete view to services and resources enables efficient use of
operator’s people and systems via an unified information model for all technologies,
modular applications and central data storage, providing as well a single point of access to
all management tasks.
Harmonization: Optimize operator’s OSS investments and minimizing system integration,
maintenance and operating costs with the help of a unified OSS platform
Automation: Improve efficiency by reducing the number of human errors and lower
operational costs through increased automation.
"A service is a means of delivering value to customers by facilitating outcomes that customers want to achieve, without the ownership of specific costs and risks" (ITIL 2007).
Service Management is a set of functions and processes for managing services over a lifecycle.

NetAct 6 & 7 New Release Model
NetAct 6 and NetAct 7 follow a new release model that is first time introduced in NetAct 6. NetAct
Base releases will provide platform and common functionalities which can be utilized in
management of different network technology domains.
Adaptation support for different technologies such as Radio and Core are included into separate
technology releases. The new release model will be taken into use in order to achieve following
benefits:
Network element support for different technologies (Radio, Core) can be released separately
from each other (even one at a time), and separately from platform and applications.
Improved flexibility to respond to operator demands.
New system level and application features can be released separately.
This is a major change from OSS5.x releases where platform, applications and adaptations are
delivered in one release only.
NetAct 6 and NetAct 7 consist of separate NetAct Base releases and technology specific releases.
NetAct Base 6 & 7 are the main releases that provide a new platform and network management
application functionalities for the management of different network technology domains.
NetAct 6 & 7 releases are running on a new computing platform, using the same hardware types as
NetAct OSS5.x. NetAct Base 6 & 7 and EP’s provide the platform and applications for management
systems of different technologies (for example NetAct for Core and NetAct for Radio).
NetAct 6 and NetAct 7 can also be seamlessly integrated with NetAct OSS5.x with a loosely
coupled interface, bringing improved assurance capabilities for NetAct OSS5.x customers. In this
scenario extra hardware units needs to added to existing OSS5.x system.
NetAct 6 & 7 software platform provides a new desktop which is used to manage and monitor the
network. The new monitoring tools, new NetAct administrator applications, and also NetAct OSS5.x
applications can be launched from the new desktop. NetAct 6 & 7 can act as a multi-technology
network management system, or as a single technology-domain-specific management system.

NetAct is based on open interfaces and industry standards such as the Next Generation OSS
(NGOSS), the third Generation Partnership Project (3GPP) and the TeleManagement Forum’s
eTOM model (Business Process Framework).
Within the telecommunications industry different Management Models have evolved over time. The
OSI Functional model – the Service Management Function Areas – introduced the functional areas
known as FCAPS: Fault Management, Configuration Management, Accounting Management,
Performance Management and Security Management. The ITU-T TMN introduced the concept of
the Logical Layered Architecture with the Element Management Layer, Network Management
Layer, Service Management Layer and Business Management Layer.
As investment decisions in the telecommunications industry were more and more driven by
Business rather than Technology drivers, the TeleManagement Forum developed the Enhanced
Telecom Operations Map® (eTOM) as a reference framework for classifying all business activities
The eTOM reference framework has multiple groupings for the processes that it contains:
Vertical process groupings: Focusing on end-to-end activities (for example Assurance) each vertical links together the customer, the supporting services, resources and supplier/partners. Taken together, these vertical groupings can be visualized as a ”lifecycle” view moving left to right across the Framework from the initial strategy for the products and their components, through development and delivery, and on into operations and billing.
Horizontal process groupings: Focusing on functionally-related areas, like Customer Relationship Management. These groupings can be visualized as a “layered” view of the enterprise’s processes, moving from top to bottom, with the customers and products supported by the underlying services, resources and (where relevant) interaction with suppliers and partners.
Linking eTOM to the TMN model
A mapping between the eTOM to the TMN model has been developed and included in the M.3050 Supplement 3 ITU-T Specification and is expected to help with validating and completing the eTOM process analysis work in the relevant process areas.
Since functions are what vendors are going to deliver, and processes model how service providers are going to sequence those functions, the mapping also provides a means to match the service providers requirements with the vendors capabilities.

The role of NetAct in managing a network can be classified into two categories: NetAct
operation system itself and NetAct Advanced products.
NetAct operation system (NetAct OS)
A NetAct system is connected to one or more Network Element(s) and / or Element
Management System(s).
• Used for online monitoring, administering, configuring and reporting of the network.
• Provides the main connection point of Network elements.
• Stores all detailed data collected from NEs. The storing time is intended to be short. (e.g for
alarms the default storing time is 2 weeks), as long term storage of information is reserved
for higher level systems (external systems or NetAct Advanced Products).
NetAct Advanced Products
The Advanced Products are an umbrella solution that provide an entire view of the network in
areas of Fault Management, Performance Management and Configuration Management.
There are two NetAct Advanced Products: NetAct Advanced Monitor and NetAct Advanced
Configurator.
Multiple NetAct instances and other Network Management Systems or other vendors (MVI)
can be connected to a single NetAct Advanced Product instance.
The Advanced products can also be integrated to the previous NetAct version OSS 5.x

Introduction to NetAct Start
NetAct Start is a centralized launch pad for starting NetAct user interface applications. You can start
all the NetAct applications that have been configured and for which you have permission to launch
from NetAct Start.
NetAct uses Single Sign-On (SSO) for accessing applications through NetAct Start. To be able to
access applications through NetAct Start, a user must have a valid user name and password. The
user also must be granted the permissions for accessing the needed applications. Depending on
the permissions granted for the user, a list of published applications is visible to the user.
From the right-hand dropdown menu the user can select between two different views.
Folder view shows the different fragments as folders. The applications are grouped into the following functional areas:
Administration: Applications for administering adaptations.
Configuration: NetAct CM applications, License manager and Software Manager.
Monitoring: NetAct Monitor.
Reporting: NetAct Reporter.
Security: Certificate and user management applications.
User Assistance: Operating documentation library.
Clicking the Online Help icon opens the Online Help Browser. By selecting ‘Show all applications’ from the dropdown menu the user can see all the applications in one view and access them by mouse click.
All the Java applications are installed on the application server cluster when NetAct is deployed. When a Java Rich Client is accessed for the first time, it is downloaded by the JWS to user workstation and launched for the user. The next time it is accessed, the application is started from the local JWS cache. JWS checks the version of the application every time it is launched on the user workstation, and if necessary, updates the application from the application server.

NetAct Configurator
NetAct Configurator is a component in the scalable NetAct framework for operating mobile networks. Configurator gives access to real-time network configuration data and provides tools to manage network configuration. The basic functionality of NetAct Configurator is to define and manage parameter data in the network.
Network architecture can be functionally grouped into the access network and the core network.
The access network handles all radio-related functionality while the core network is responsible for
routing calls and data connections to external networks. With Configurator, the access network and
core network are managed in a centralized way.
The main functionalities of Configurator are:
• storing the network parameters in the database
• data exchange with external tools
• setting, modifying, viewing, and comparing network configuration data
• mass modifications on the network: integrating sites, extending and optimizing the network
• small scale tuning of the network configuration

NetAct Configurator - Maintaining up-to-date picture of the network
Working with the latest data is a precondition for exploiting the full potential of any network.
Configurator not only retrieves configuration data from network elements whenever desired. It also
saves this information to allow operators create an archive of configuration stages to give them vital
insight and thus enables them to optimize their network. Built-in northbound interface capability
allows for the export of data towards third-party post-processing applications.
Configuring the network
Configurator provides offline planning capabilities to prevent any mistakes to be made on a running
network. Current and planned configurations can be compared to identify the best solution.
Plausibility checks prevent errors from the start. An Import functionality is available which enables
to process network plans which have been prepared outside of Configurator in an operator’s
planning environment.
In the configure phase all three Configurator components work hand-in-hand:
• CM Editor is used for displaying configuration data and for comfortable editing of data when creating a
network plan.
• CM Analyzer is used for use case specific running of consistency checks.
• Finally, CM Operations Manager comes into the game when externally created network plans are imported
into the Configurator application for further processing. With the Command Manager, CM Operations
Manager allows the direct execution of commands and command files (on-demand or scheduled) to network
elements.
Once a new configuration has been defined automatic delta command generation takes care of
spelling out all necessary changes in the relevant network element specific data formats. Controlled
deployment of all administration is provided by the provisioning capability.
The automation of all download tasks ensures network consistency and minimizes operational
efforts, allowing a complete transparency of all planning and with minimized margin for error. All
provisioning steps are controlled by the CM Operations Manager.

NetAct Reporter
NetAct Reporter is a group of tools integrated to the network management system solution of Nokia
Siemens Networks for centrally monitoring network performance.
You can use the data that NetAct collects from the network and generate various reports for
analyzing current and anticipating future trends. You can use the reports and statistics that you
generated with Reporter applications as a basis for decisions on the optimal timing of new
investments or for evaluating the utilization of resources. When the utilization of the network
resources is evaluated, both the overall performance of the network system and the performance of
individual network elements are handled. Identification of bottlenecks and optimization of the
network system is particularly important.
In NetAct Reporter you have access to the following features:
Report Editor
Report Explorer
KPI Editor
Scheduler Admin

The primary aim of effective network monitoring is to prevent critical faults in the network and to
identify the problems that directly affect the quality of the service, criteria by which subscribers
judge the quality of the network. If no event reduction techniques are implemented, network
monitoring becomes a reactive process, where an enormous flow of events arrive from all parts of
the network. This reactive job includes:
Filtering the enormous amount of information that is presented by events.
Deciding which of the thousands of events that are visible in the event handling applications
are important.
Making correlations between events and trying to decide which of them are caused by the
same original fault, and grouping those events together.
Finding solutions for the problems that cause the events.
These daily activities require constant and intensive attention in network monitoring. If strategic
decisions have to be made under pressure, there is a high risk that service affecting faults remain
unnoticed or unresolved, which results in a decrease in the quality of service.
The Assurance Desktop of NetAct Advanced Monitor integrates a set of tools to perform
comprehensive event filtering and event correlation, based on rules. These rules can significantly
reduce the event flow towards the User Interface, the most obvious result is the prioritization of
events resulting in a fast fault detection and root cause analysis.
Service monitoring gathers all sorts of information from the network in a holistic way, and can model
the customer’s perception of the service. NetAct Advanced Monitor offers the following set of
functions to monitor services and manage the system:
Defining, Monitoring, Analyzing Services
Reporting on services and their problems
Once a service has been defined, NetAct Advanced Monitor continuously monitors the service.
Monitoring, visualization and analysis are carried out as a permanent process.

NetAct Advanced Configurator (NAdC) is an optional solution on top of NetAct OSS5.x and NetAct6
& 7 to make a network level workspace for configuration management tasks. NAdC provides
network wide view of configuration management data and workflows, with features such as:
Powerful set of tools: from the smallest of changes to large network retunes, Configurator tool
allows end users to proficiently and accurately perform network configuration management tasks in
a systematic and efficient manner. This provides major OPEX savings while improving the overall
quality of the network.
Network level data storage provides a seamless view to all data from integrated systems and
typical operations and planning team tasks can be performed in one system.
Harmonized network model for the common parameters from all vendors enables working on a
single model instead of managing all the vendor specific models and parameters.
Vendor specific models are providing support for all the same adaptation content for network
elements and releases that is available in integrated OSS/EMS system.
End to end coverage of network management use cases, e.g.: Consistency check and audit of the
network and Border area adjacency management (e.g.: inter-EMS adjacency management)
In practice any user defined task sequence is a candidate for automated single operation with CM
Workflow Manager
Single standard integration point for other OSS systems:
For configuration management other OSS systems do not need to integrate each of the
vendor/technology systems anymore, instead they integrate to one single system: NetAct Advanced
Configurator
Configurator provides standard interfaces (e.g.: Bulk CM XML and CSV) for both import and export
directions. Other OSS systems do not need to care anymore about the variety of proprietary
protocols used by its different providers
Continuously developing Multi-Technology features and synchronized support also with NetAct
OSS5 and NetAct 6 & 7 systems.
