1. Introduction

Next Generation Network (NGN) is a packet-based network where the packet switching and transport elements (e.g., routers, switches, and gateways) are logically and physically separated from the service/call control intelligence. This control intelligence support all types of services over the packet-based transport network, including everything from basic voice telephony services to data, video, multimedia, advanced broadband, and management applications, which can be thought of as just another type of service that NGNs support [2]. This paper discussed about the requirements for the network management system for (NGN) and provides solutions implemented by NEC.

2. Problem Statement

The network management system for the NGN should efficiently run the critical management operation cycle. In this case, the fault management should work with maximum productivity and minimum wasted effort or expense.

The carrier environmental changes from measured rate voice communications to multimedia service delivery become popular and have very high competition in services and prices.

3. Objective

The first objective is to enhance the operation management system. Next is to evaluate the network quality and fault information according to some specific areas. Another important factor is to improve the operation efficiencies and pursue customer satisfaction. Lastly is to collect accurate information and guarantee high-quality NGN services and support.

4. Methodology

To achieve those objectives, we have to consider enhancing the operation management system. To deal with this enhancement, 4 steps of operation management system have been discussed.

Figure 1: Direction of Operation Management System

Here we start with the Real time Business Strategy Support System. At this stage, it will provide traffic predictions and generate analysis of customers to get the idea of any sign of unsubscription. In NEC, all the measures taken are for investment decision and to promote customers satisfaction (CS). Investment decisions will predict quality degradation or improvement after perform equipment extensions, customer complaints, and estimate time to resolve any problems. CS Improvement Support categorizes and evaluate network quality and fault information according to time, area, equipment and services. At this function, customers complaints will be evaluated and use to predict the potential of customer degradation.

Second stage in operation direction management system is Real-time Customer Care Service System. This function is focusing on improving the operation efficiency by speeding up the operation to reduce time taken while providing services.

NEC implemented this function and divided into three segments. The first segment called Service Order Operation Flow, second segment called Business Process Management (BPM) and lastly is the virtual databases. Customer access the first segment to communicate with operators. Information and queries created as scenario and linked to the Operation Flow Database in BPM segment. BPM segment linked to the virtual databases using an adapter. In the third segment, the virtual database divided into 3 specified field of information for easy and efficient data management. The operators that perform real time customer care will be placed at the BPM segment.

With this automatic distribution and linkage, data collection and prediction will be accurate. Operators will provide correct information to customers and increase the speed of the operations for customer’s inquiry.

Next is the End-to-End Management. This stage focuses in providing high-quality NGN services and support quick failure recovery. There are 3 components in this function which, QoS Analysis System, VoIP Quality Measurement System and Fault Localization System. QoS Analysis System used to measure quality of the communication network. It analyze TCP, UDP/RPT (Real-time Transfer Protocol) using some IP packet as a sample. With this analysis, any network failure can be detected and isolate the service. For VoIP Quality Measurement System, it measures the voice quality. There are a large number of technologies that can be chosen to provide QoS support such as Diffserv, RSVP,MPLS and even ATM [1]. Data collected are stored in the server for voice quality status management for the network. Final component is Fault Localization System, which used to estimate the root cause of silent failure in real time. To perform its function, this component need the information collected from QoS Analysis System, and path information from path management of the NMS. At this moment, End-To-End QoS Management only

Lastly is the Integrated Element Management System (EMS), that used to construct more effective operations management system for migration to IP/NGN using IP Management System (IMS). At NEC, the integrated management used to deal with acceleration of all IP migration. In this element, it has 3 functions, Operation and Maintenance System, Billing mediation (billing MD) and service Order Gateway (SO-GW) to reduce OPEX, CAPEX, Syatem Integration Cost, and market time issues. OPEX or operating expense, operating expenditure, operational expense, and operational expenditure is an on-going cost for running a product, business, or system[ ]. With the integrated network management, the NEC improve the operation efficiency and can reduce the OPEX.

CAPEX is the cost of developing or providing non-consumable parts for the product or system. With integration, number of server can be reduced, save investment, management and maintenance cost. Scalability achieved when it enabled small start new service operations or when performing large network integration of from radio to core networks.

Integrated EMS can provide single interface to the NMS instead of having multiple developments and tests for the NMS for its compatibility with various interface of EMSs. Because of that, cost has been reduced. Finally, with integrated management function that complies all services in networks, it can prevent the loss of opportunities by time to market.

5. Critical Review

Competitions in services and prices become more critical. Large equipment for infrastructure investment, decision investment, and quality enhancement should be made quickly to improve competitiveness. At the same time, the quality of services and reliability should be maintained.

6. Future Enhancement

The next target is to provide service management functions that reduce customer awareness regarding the IP address.

7. Conclusion

This journal has described about the requirements for the network management system for Next Generation Network (NGN) and the implementation at NEC. The requirements are, Real-time Business Strategy Support System, Real-time Customer Care Service System, End-to-End Management and Integrated EMS. The purpose of these requirements is to enhance the operation management system so that it can run efficiently and quickly on the open network infrastructure.

Pomelatto

...Pomelatto and Mass Customization Assignment After checking the Italian jeweler Pomellato's website and doing some research about what the company has been doing in terms of mass customization, a few worth mentioning points can be made: Italian jeweler Pomellato is revitalizing the image of three of its classic ring designs with art-house films meant to display the brand’s emotion and dedication to creativity. Pomellato’s “Icon Movies” film series pays homage to the jeweler’s Nudo, Capri and Sabbia collections and shows both the personality of the filmmaker and his subject. Outsourcing creative initiatives to young talent can help a brand acquire new enthusiasts by positioning its products in front of younger consumers. Paula Rosenblum, managing partner at RSR Research, Boston, thinks that it is all about keeping the imagery of the jewelry timeless, yet up-to-date. In the case of Nudo, for example, you have fresh talent with echoes of Madonna and the Rolling Stones, which is pretty contemporary to Pomellato’s beginnings. In its own way, in Capri, we see a lot of similar concepts, a memory of past special moments with the ring as the reminder; all interpreted by young, interesting talent. Finally, in Sabbia, we seem to go all the way back to the start of the universe and a reminder that matter existed long before we, as human beings, did, and likely will go on after us. Ms. Rosenblum, an industry expert, stated that Pomelatto, acquired by luxury conglomerate Kering...

Airframes and Flat Panel Antennas Match

...than a luxury, the need for lightweight, low-cost, and high performance satellite terminals has driven the evolution of ground segment equipment, for which flat panel antennas (FPAs) have emerged as the most popular innovation in recent years. The limited speed and large size of mechanically-steered and the 1st generation of electronically-steered flat panel antennas drew many to wonder if the Holy Grail of the satellite world – a cost-competitive, electronically-steered flat panel antennas with an ultra-low profile- would ever be within reach. But the journey to this goal has been a long, difficult one because of the many desired features of such a product as depicted in the figure below. NSR has often noted the tremendous increase in satellite mobility bandwidth demand has driven many operators to add new HTS systems and constellations to meet this demand. But at the same time, the industry metric has put more emphasis on cost-efficiencies, which is where NSR expects flat panel antennas (FPAs) to play a key role in this transformation. As service providers look to provide more bandwidth at lower cost to end-users, falling capacity prices, next generation modems with beam switching capabilities, and better software are icing on the cake of the HTS capacity onslaught, in which FPAs are a perfect fit. In NSR’s recently released Flat Panel Satellite Analysis report, both the mobility and fixed satellite side of the business were analyzed, and commercial aeronautical...

...are differences in certain characteristics described by both authors. Galarza’s essay focuses on an immigrant point of view arriving into Sacramento versus Didion’s experiences as a native decedent of Sacramento. Joan Didion’s Sacramento is a very different place compared to Ernesto Galarza’s , for him it’s an immigrant place where Mexican, Yugoslavs, Chinese and many other different cultures come together to make one home. For Joan Didion, Sacramento is a place that with the pas of time and the changes that has come with time, have forced memories to be lost and most importantly identities. Didion highlights the true nature of Californian lifestyle and how with its gradual disappearance more than the past is being lost, but a new generation is also losing an understanding of its true roots, its true history and as a result a loss of knowledge. The loss of knowledge is equivalent to the loss of identity because if one doesn’t know where they came from how one can truly know who they are. Didion talks about her own experiences as a child in Sacramento and adulthood. She compares how much Sacramento has changed since she left. For example, in her essay Didion observes the changes in Sacramento beginning with the introduction of industrialization; she mentions that prior to modernization, Sacramento was nothing but an isolated land mass and with the discovery of gold Sacramento abruptly developed into a town and later on a city.

The Contribution of Enterprise Systems

...The Contribution of Enterprise Systems An enterprise system is classified as a system of integrated application-software packages that use data storage and transmission to support the flow of information, reporting, and analytics in the company as well as in some cases it is used outside of the company by colleagues and clients. Enterprise systems manage the flow of information relevant to those within the company as well as those outside of the company that have permission to access certain information. If a company has multiple lines of products and information that is relevant to all products such as statistical data that needs to be shared with all people within the company, an enterprise system exists to enable the sharing of information. An enterprise system provides as single system central to the organization which ensures that the information can be shared across all management and functional levels Enterprise systems are also invaluable with elimination of problems with information fragmentation which can be caused by having multiple information systems in an organization. It does this by creating a standard data structure. Typical information systems are housed in data centers and would run enterprise software as well as include application such as; content management systems that would cross organizational borders. Enterprise systems provide value for increasing operational efficiency, as well as provide wide information to help managers make informed and effective...

Androids and the Mind/Body Problem

...Androids and the Mind/Body Problem In a Star Trek, episode of The Next Generation, Captain Picard of the enterprise is left with the job of defending an android by the name of Data, whom believes he has the right to say no to a direct order for him to be disassembly by the Commander Bruce Maddox. Although Data is an Androids which basically is a machine, Picard defends him using the dualism theory. Picard shows that Data has two aspects, he is a machine but like humans Data processes a body and mind, which are not identical even though his mind is program he is able to make decisions on his own. I think Data is a perfect example of the dualism theory; he has the elements which are mention above, so many philosophers have debated whether there is such a thing as a soul with Data Picard did not need to establish that. Data is the perfect display of the Mind/Body problem, the issue between mind and matter, whether he is a person or property. Picard saw an entity that had a body and mind, an entity with the dualism theory; having both a body and mind wouldn’t that make you a person? I would think a body and a mind that can function on its own would be considered a person. Commander Bruce Maddox saw Data as machine, he saw him for what he was built to be, and to do serve mankind.

...Technology: It’s Effect on Our Youth Growing up I remember playing outside all day, enjoying the outdoors, and riding bikes down the dirt roads, trying to find some new adventure to get into. Looking around now, I notice teenagers glued to their phones when they are out eating, walking around and even while driving. It seems like a lot has changed since I was a child. Technological advances have made our way of life easier by making communication faster than ever before, improving production rates, and making it easier to access information. However, with the good also comes the bad. I have noticed an increase in the time children spend inside, as opposed to outdoors, the changes in behavior of children and teenagers, and the decline in personal interaction. I believe that technology, if not used in moderation, could have a negative influence on our youth. I have noticed the significant change that has occurred in technology in just a generation’s time. As a child, I remember when people were purchasing their first personal computers, usually for everyone in the household to share. These computers were not nearly as fast and advanced as computers are today. Now, nearly every home in America has a personal computer, laptop or some other way of accessing the internet, like a smartphone or tablet. While access to the internet can help educate children if used in an educational way, misuse of technology, like playing violent video games, could cause a setback...

A Rose for Emily

...from the older generation. In William Faulkners’ story “A Rose for Emily”, the nonlinear narrative indicates that time will aid in the development of the story as well as the characters. However, a close look at the manipulation of time, suggests that Miss Emily, herself will come to represent time and change in her community over the decades. The tension between the new generation and Miss Emily indicates her inability the grasp the realism of time. William Faulkner uses progressive time shifts to compare the past and present and their influence upon on another. Miss Emily made an agreement with Colonel Sartoris to not pay taxes because her father had loaned the town money. When the next generation came into office, “this arrangement created some little dissatisfaction” (Faulkner). Miss Emily failed to respond to the tax notice that was sent to her by the new aldermen and mayor. She believed that the new generation should honor the non-official agreement set forth by her and Colonel Sartoris and “perhaps one [of the new aldermen] can gain access to the city records and satisfy [themselves]” (Faulkner). After a non-successful visit to Miss Emily house to collect her taxes, she puts the gentlemen out of her house because she still believes she “has no taxes in Jefferson” (Faulkner). Miss Emily struggles to conform to the ways of the new generation. Through the progression of the story we continue to see Miss Emily inability to accept change and the new generation.
