    Enterprise networks constructed in recent years have rarely composed one service offered by one company. Instead, they have typically combined various services provided by various carriers, with connections between IP-VPN, large-area Ethernet access networks, DSL providers, and so forth. Under these conditions, providing fast services according to customer needs requires information on related enterprises for flexible integration of the mechanism. To provide a method of meeting this requirement, we applied semantic Web and ontology technology to achieve information integration between enterprises. We examine the resulting system, which enables flexible cooperation. View full abstract»

    The management of huge, heterogeneous and highly distributed networks is a very complex task due to their low degree of integration. Such a network is that of Telemar, the largest telecommunications company of Brazil. The plant is composed of a large variety of switching equipments and transmission systems, differing not only by their vendors but also by their technology, age and way of monitoring and control. In order to solve that management problem, a distributed management platform called SIS (system for integration of supervision) was developed. This platform is fully operational and implemented in a real telecommunications plant. SIS has been evolving since the mid 1990s, when it was initially deployed. The platform was conceived to allow the management of new systems and showed to be a key factor for the company as its business focus also evolves (e.g., the management of data communication networks of other companies such as a bank, an airline company, and a large retailer). We discuss the development and use of the SIS platform, its design and main modules. View full abstract»

  • Operating mobile networks through effective network inventory management

    Page(s): 31 - 44 Vol.2
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1137 KB)  

    The paper presents a technical solution for the automation of network inventory management (NIM) processes for mobile operators. The deployment of operations support systems (OSS), according to the design of an overall target systems architecture, and the reengineering of management processes supporting NIM are the core issues of the proposed solution. Common information and data models are key enabling factors for NIM processes and systems. Information modelling is also the core of standardization efforts for network and service management. Within the operating environments of telecommunication companies (telcos), running either wireline or wireless networks, NIM and the centrality of data have appeared to be key factors for enabling automation of network and service management and deploying effective OSS solutions. The theories and the results discussed have been demonstrated practically and successfully in the operating companies of the Telecom Italia Group. Software solutions for the automation of NIM processes have been deployed since the early 1980s, using early software technologies for database management and building bespoke systems, until some more recent implementations that exploit best-in-class commercial products and successful Web technologies. A practical case study is presented of a successful implementation of an OSS solution for NIM in a mobile company of the Telecom Italia Group. View full abstract»

    Due to the rapid change in the mobile business environment and a variety of services, KTF has several network management systems. Each network management system has been specialized for each network such as NetCommander for 2G/3G (cdma2000) core, access and some supplementary networks, NexPlorer for 2G/3G IP network and iManager for 3G (W-CDMA) networks. However, market situations push operators to reduce capital expenditure (CAPEX) and operational expenditure (OPEX). With these several network management systems, we think that we can not meet the time-to-market and reduce the operational expenditure (OPEX) due to a variety of interfaces to handle and a variety of vendor products to manage. In this presentation, the author talks about the plans for the integration of KTF's legacy network management systems. We plan to reassign the roles of our network management systems and unify the interfaces between network management system and EMS/agent. With these plans, we are going to implement a unified network management system and cut the operational costs. View full abstract»

  • Building a service assurance system in KT

    Page(s): 73 - 86 Vol.2
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (758 KB)  

    For the past several years, new Internet-centric services have rapidly entered the stage and have been supported by complex networks based on the PSTN, ATM, metro and so forth. These require modifications to current business processes in the OSS. Alternatively, they could require new systems. We have faced difficulties in adopting new data or Internet services in time to market because of complex system structures, inter-operations, etc. To address market needs, we have been promoting the NeOSS (new operations support systems) project since 2001. We have just completed its design level, and are currently implementing it. In these processes, we are still facing many problems and difficulties. We focus on "service assurance", and describe what the problems in the KT OSS are, and how we are approaching them from the point of view of the architectures and technologies and of inter-operations with legacy systems. We also provide an economic analysis based on the key indexes of the KT NeOSS project. View full abstract»

  • An NGOSS-based automatic service delivery system using EAI technology

    Page(s): 87 - 100 Vol.2

    In a next generation network (NGN) service environment, telecommunication service will continue to change from technology-oriented service to service-oriented service and customers will demand value-added Differentiated Services. To succeed in this business environment, service providers must support the evolution of next generation services and change their existing operational support system (OSS) into a highly distributed, loosely coupled and open-standard based OSS architecture. Also, OSS must shift to include business-oriented aspects. For the NGN telecommunication management, the Telemanagement (TM) Forum has developed a Next Generation Operational Systems and Software (NGOSS) architecture. One of the cornerstones of the NGOSS is the e-TOM business process model. In the service delivery management point of view, in the past, service delivery steps mostly depended on manual jobs and were based on single domain and single technology based-service delivery architecture. This has been a bottleneck, and has prevented flow-through and integrated service delivery in NGN service environment from being realized. An NGOSS-based automatic service delivery system using enterprise application integration (EAI) technology, including business process automation service using workflow, messaging service using a common messaging bus and XML messages, and connectivity service using transport protocol adaptor framework, will allow OSS developers and service providers to quickly automate business processes across the enterprise which are extendable to allow for new services quickly and easily.

  • Applying a service-on-demand policy management framework to an ETTx environment

    Page(s): 101 - 114 Vol.2

    This paper presents a service on demand management framework to support dynamic service creation, and a system which instantiates this framework for an Ethernet-To-The-Home/Business (ETTx) service environment. The service-on-demand framework delivers two major functions: (1) it allows service providers to create new types of service dynamically through a policy-driven "service building" process; (2) it allows end users to subscribe to a service and have their service orders fulfilled in a fully automated, near real time, and "zero touch" fashion. We have applied this framework to build an industrial strength service fulfillment system geared towards ETTx access networks. Those networks represent one of the most dynamic service creation environments today. View full abstract»

  • A method for the end-to-end testing of VoIP service networks

    Page(s): 117 - 130 Vol.2
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (448 KB)  

    While methods of end-to-end testing for the PSTN (public switched telephone network) are well-established, this is not the case for VoIP (voice-over-IP) networks. In a VoIP network where the carrier is large-scale (numbers of network elements and sites are large), we should be able to realize end-to-end testing mainly by combining commercial products, such as monitoring tools and test-call generators. We propose a system for the end-to-end testing of networks at the carrier level, clarify the technical elements that the system will require and conditions that apply, and describe a suitable software structure.

  • Traffic engineering in cable-data system : maximizing CMTS port utilization

    Page(s): 145 - 158 Vol.2

    CMTS has played the key role in HFC's cable-data system, and its port resources are the key factors that manage a operational group of subscribers. Usually a port is provisioned to manage a cell which covers the geographically grouped subscribers in an HFC network. Since each upstream or downstream port has got a certain capacity, too many subscribers assigned on a CMTS port make all the subscribers suffer from bandwidth contention. That is why service providers put a limit on per-cell subscribers (ie. 200 subscribers per cell). However, putting equal limit on the number of subscribers among ports has been proved not useful any longer. The paper discusses how to maximize the port utilization from the service provider's viewpoint, especially by traffic load balancing. The method suggested is highly dynamic, economical, and has been implemented and field-tested. The paper shows not only the traffic engineering mechanism, but also the result of the test applying the mechanism. View full abstract»

  • Supplementary services in telecommunication next generation networks

    Over the neat few years the public-switched telephone network (PSTN) will evolve into next-generation networks (NGN), in which data and voice will share a common packet-switched network. The NGN introduces new concepts and networking protocols for the 'everything over IP' strategy. The Softswitch, the media gateway and the signaling gateway are the basic elements of the current NGN architecture. In this paper we show that these elements do not meet the requirements of some SS7 ISUP supplementary services that are widely used in telecommunication networks. The major drawbacks of the current NGN implementations that are based on those services are investigated. To overcome these drawbacks we propose a new element in the NGN architecture, called multi-service mediator (MSM) and describe an interworking scenario with other currently defined NGN elements, especially with the Softswitch. We investigate requirements for controlling and management of MSM in NGN. Additionally we propose a building block for simulation of the NGN architecture, including MSM. View full abstract»
