Our society is increasingly dependent on the Internet, and this trend will be accelerating in the ear of All-IP convergence. As the core infrastructure of the All-IP convergence, the next generation Internet should enable end-to-end Quality of Service(e2e QoS). For that purpose, major international standardization institutes such as ITU(International Telecommunication Union) and IETF(Internet Engineering Task Force) are building the concept and architecture of the Next Generation Network(NGN). However, these institutes focus only on technical issues, and leave many business/policy-oriented challenges unresolved. For example, the standards raised by ITU assume that the entire service delivery process for e2e QoS services is perfectly working. But required is a standardized business interface and process for seamless inter-operations across many stakeholders including ISPs(Internet Service Providers), CPs(Content Providers), so on. On the other hand, TMF(TeleManagement Forum) and QuEST(Quality Excellence for Suppliers of Telecommunication) Forum, global consortiums of telecom operators and vendors, present sets of interface rules and process which playa crucial role as de facto standards: for example, NGOSS/eTOM and TL9000 authorization system. However, these standards focus on telephone services, and provide little principle for the next generation Internet. Our study seeks a way to combine these two strains for a successful implementation of NGN. In particular, we find a missing link in the NGN architecture and the elements that could be complemented with the help of NGOSS/eTOM and TL9000. Finally, presented is a strategic direction that our standardization policy should purse in order to reinforce our global leadership for the next generation Internet.

A various multimedia application services should be developed with techniques of high speed networks and computer. Among these, video-conference system over Internet is useful and important, and the standardization for it should be showed in ITU-T H.323. H.323 standardization consists of four components such as Terminal, MCU(Multipoint Control Unit), Gatekeeper, and Gateway. Among these, the functions of Gatekeeper are as follows, firstly the address translation service to translate the alias address into the IP address, secondary conference admission control service to control of conference start and termination, thirdly bandwidth management service for H.323 terminals. In this paper, we implemented the Gatekeeper for an efficient management of video-conference components in Internet environment, and will introduce our system. As the experimental results with CUSeeMe and Netmeeting which are well-known H.323 terminal, it is known that our gatekeeper should be satisfied with H.323 standardization.

This article presents spectrum sharing policy trends both overseas and domestically. The Federal Communications Commission recently adopted rules for the commercial use of a 150 MHz bandwidth at 3.55 to 3.7 GHz, which has been utilized for defense and satellite services. This frequency band for spectrum sharing is called the citizens broadband radio service (CBRS) band. In Europe, the related regimes for licensed shared access application at 2.3 to 2.4 GHz has been organized, and interface standardization for sharing frequency information has been completed. In Korea, efforts are being made to establish spectrum-sharing policies to improve the efficiency of the frequency utilization. This article also introduces both the IEEE 802 local area network/metropolitan area network and 3GPP standardization activities with regard to frequency sharing technologies. To effectively solve the spectrum-sharing problem in IEEE 802, standardization activities on the CBRS and the mid-band (3.7-24 GHz) are underway. 3GPP is currently developing the standardization of a licensed assisted access technology, which extends mobile communication services provided in the licensed band to unlicensed bands.

The environment of Information and Telecommunication industry has rapidly changed. This is leading the growth of the world economy. Because of the characteristic of the information and communication, the standardization plays a important role in this market. The company that owns the standardization in its industry has dominant power like Microsoft in personal computer software, and Qualcomm in digital cellular phone system. Therefore, to take advantage of this standardization power, it is important to find which technology will be set up as a new standard. This paper presents how to capitalize the standardization as a market strategy. To perform this strategy, we take two steps. The first step is to strategically choose the most important technology or service which would lead the information and telecommunication market. We used modified AHP(Analytic Hierarchy Process) to set the priorities among the various standard related technologies and services, We interviewed with the information and telecommunication experts to find out some criteria and the weights of them. The second step is to select the standard to realize the technology. Actually, this is very hard to decide which technology we should select, because there are lots of alternative standards to develop the technology. In this step, we use a strategic framework for choosing the standard. This framework provides how the research institution and company do to get a maximum benefit from the standardization strategy, Finally, we applied these to Korea's situation simply in order to show how to take advantage of the framework.

Recently, growing Internet traffic have come to mandate the speed-up of Internet links. Also, emerging real-time services generally require QoS (Quality of Service) guarantees in networks. ATM is considered to be the most promising subnetwork technology to meet these requirements efficiently. In this paper, we first analyze recent protocol standardization activities in IETF and ATM Forum for integrating Internet with ATM. This includes brief reviews of protocols such as IETF's IP/ATM, NHRP, RSVP and IS/ATM, as well as ATM Forum's LAN Emulation and MPOA. We then identify two types of integration methodologies, and suggest a classification of the integration. Our work might be helpful to outlook better the future direction of standardization in this field.

The current consitutional law 29-1 is ordaining the State Tort Liability for the illegal action of public service personnel. Based on this regulation, the State Tort Liability Act 2-1 actualizes by indicating, the nation or the local self-governing community is responsible for the public service personnels damaging others during their office hours whether it is accidental or intentional. However, the same law is considered to be inappropriate for the damage relief. In order to supplement this problem, through examinations at both theoretical and systematic levels of Prima facie as well as the objectification and standardization of the damages are required for the national compensation for the police action. According to the objectification and standardization of the damage theory, the faulty actions of the public service personnel are the defects occurred during the office hours. In the case of the police action that frequently uses infringement administration, invading the liberty and rights of the people, it is necessary to interpret faulty damages during the office duties more comprehensively so as to extend its scope of the ordinary public service personnel accidental illegality. In order to warrant effectiveness of the securing the rights, it is crucial to distinguish whether the faulty actions are accidental or intentional. When proven to be damages by illegal police action, the police personnel is responsible for the faults, called Prima facie, the nation is liable for the damage relief.

Electronic devices in railway vehicle perform various functions such as not only braking and propulsion but also monitoring of vehicle condition, on-line diagnosis, and passenger information service, etc. These devices, distributed in vehicle, should be efficiently connected so as to properly perform the functions. IEC (International Electro-Technical Commission) standardized train communication network (TCN) as IEC 61375-1, -2. TCN can reduce the interconnecting work load by reducing the number of wire-line, compared with existing hard-wire connection, and it brings the efficient control by enabling various devices to share the information. But existing TCN can not satisfy the increasing service demands like passenger internet access and CCTV surveillance, etc. In this paper, we investigate ECN (Ethernet Consist Network) and ETN (Ethernet Train Backbone) which are proposed to satisfy these demands and in the process of standardization by IEC TC9 WG43.
