A principle requirement and technical standardization for numbering plan is required to B-lSDN network planning. Especially, internetworking high speed network with other conventional networks like PSTN, PSDN and ISDN is generally considered for integration. This paper describes the numbering plan for operation between internet and ATM. And based on the ITU-U specification, numbering plan is compared between conventional and high speed networks. Additionally, numbering plan for ATM-forum is analyzed.

Communication network numbers are used in classifying each kind of network, identifying the communication companies and choosing services that are supplied by the companies. In the present, a new numbering system is needed to distinguish a new additional communication network. However the present numbering system of domestic communication network has some problems such as exhaustion of network number, excessive local numbers, and so forth So, in this thesis we call the wire and the wireless telephone network, the pager network and the personal number as communication networks, and consider the present condition and problems of our country, Korea, and foreign countries. Then we propose the efficient numbering plan. Firstly, the present 10 numbering systems that are distributed, such as communication networking number $\ulcorner$01X$\lrcorner$ are diminished into 5 communication network numbers that have same quality. Secondly, subscriber numbers are united to 8 digit and 144 area codes are made into widened 5 area codes. Thirdly, the personal numbering services are cross-distributed by century. And we examine the technical convening plan and the legal converting plan and investigate expecting efficiency of proposed numbering system. If this numbering plan is executed, subscriber's number on communication networks are unified at 8 digits, 5 reserve numbers are secured in exhausted communication network number of $\ulcorner$01X$\lrcorner$, and they can distribute subscriber numbers over twice as much. In addition, number acceptability is enlarged from 237,600 thousands to 400,000 thousands. Personal number can be classified at not only century but also a decade. Accordingly, acceptable numbers are increased two folds enough to provide unification and population increase. We were able to confirm all the efficiencies.

The numbering plan, basic requirements for interworking standards, and technical standard specification for National Information Infrastructure have not been defined specifically yet. It is reviewed for the numbering plans of public/private ATM networks based on the standard specifications of W-T and ATM Forum. The specifications for numbering plan are discussed for the interworking between current various networks and National Information Infrastructure based on the related standard specification of ITU-T and ATM Forum.

In this paper, we made researches into considerations for the numbering plan for IMT-2000 that seems to be a unit system integrating cellular, satellite, PCS. The purposes of the numbering plane for IMT-2000 ARE SIMILAR TO IMT-2000 evolution form:constructing the numbering plane centering around UPT as a PRE-FPLMTS from and futhermore, adding terminal mobility to IMT-2000. For this paper, we established three numbering plans for IMT-2000 that accepts various considerations.

In this paper, We analyze and inspect the problem of our country PSTN subscriber telephone number and suggest the ISDN/PSTN subsciber numbering plan in the future. Expecially, when you eastablish plan to change present telephone number system to ISDN telephone number system, public goverment and public office which has many calls have to be given a same number that many people want and being easy rememberance thoughout the country. Therefore we think that it is saving hours and reduce lost calls. As concrete action of convert plan it must be made consistent numbering plan when the numbering reorganization is carried out in Korea before T-time. If a partial is not carried out, it should be given when the telephone number is newly-organized or the big buliding and goverment and public office eastablich RSS individually. At that time chaos will be minimized.

Which factors should influence consumer consideration to subscribe to Voice over Internet Protocol (VoIP)? Policy issues, managerial concerns, and demographic variables are possible factors. This paper discusses policy and managerial issues regarding VoIP adoption. A model that explains VoIP adoption is proposed and tested. This study analyzes a survey of 750 prospective VoIP users in Korea. The testing is accompanied by logistic regression and discriminant analysis. The results show that trust in VoIP, relative comparison of Quality to fixed service, numbering plan, satisfactions of call Quality and customer services on both fixed and mobile services have impacts on the adoption of VoIP. Implications for VoIP providers and policy makers are presented.

Although the current VoIP service is limited within the wire network, the future network will be a united network of wire/wireless. It is required that the study on the granting plan of numbering system by not considering the simple VoIP service but considering the entire network of wire/wireless. In this paper, we proposed a desirable VoIP service activation plan in mobile network suited to the future network by considering on VoIP service and mobile VoIP service.

In this paper. we dIscussed wIth the ISDN numberIng system of Korea 2digIt of NDC(National Destination Code)is assigned to the common carrier indenttification and an other the service network identification code as conbining the flIst and second dIgIt. The last ot NDC is applicable to for each area code. Resulty. we become 10 digit number for toll system vice 7 digit for local numbering. It is satisfactory to CCITT recommandtion and also. We has been suggested that existing network the mobile. pagget, FAX, TELEX and public networks are able to be connetcted to the ISDN. Near the 1994. we guess that it is fully occupied with 7 digit number to the metropolitan area to solve this problem, after divide to 3 part provincial area southern. nothem and mid-Korea. We suggested that special number system are reorganized with the new and existing service numbers plan. Although, we don't deal with the SA of ISDN numbering systems. Resultly, know that we are to design efficiently number system as 3 digit code for ISDN/NSN.
