Introduction
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. OS82121EN60GLA2

Introduction
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.

Introduction
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.

Introduction
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
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

Introduction
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.

Introduction
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.
