Telematics, one of the so-called New Growth Engine of IT839, is a leading IT service where wireless internet service represented by information and mobility is extended to the area of transportation. To provide telematics service, Telematics service provider have to connect with various Contents Provider or Service Provide server - for example - LBSS(Location Based Service Server), ASPS(Application Service Provider Server), TELICS(TELematics Information Center Server), GMS(Geo-mobility Server), WTPS(World Telematics Protocol Server) and MAUS(Map Air Update Server). Presently, It is nearly impossible or very difficult for the company that are manufacturing and testing telematics device to develop and test telematics solution without connecting Telematics Service Provider, Service Provider, Contents Provider. And, it is very difficult to connect in TSP, CP, SP having the product to be developed. In this paper, we proposed virtual telematics service provider. The proposed Virtual Telematics Service Provider is to provide telematics services and functionalities by integrating telematics servers into TSP gateway virtually. In other words, VTSP is performs with the role of TSP, CP, SP. And the VTSP support integration of telematics servers, interfacing and monitoring between terminal and the integrated servers.

This paper propose a solution to resolve data overflow or leakage when a subscriber receive data to service provider. The set-top box can communicate with a service provider and can inform the service provider its data overflow or leakage. When service provider received this control signal, it changes data transmit rate and transmits data with changed rate. The buffer of set-top box is important because incoming data from a service provider are stored by it.

A study for service quality is actively done but that for the quality level of the provided service recognized by the service provider for the same service, and for the difference in quality level of service use recognized by the service user is not relatively widely done. Thus, this study analyzed difference between the quality level of the provided service recognized by the service provider and the quality level of service use recognized by the service user, around administrative service as one of cores of the university service, and examined how difference between both service qualities have effect on business the business satisfaction level of the service provider. We measured the service level provided by the individual in charge of the administrative service of the A-university and examined the service quality in business by use of questionnaires. As the result, it was appeared that the quality level of the provided service recognized by the service provider for the same service quality was higher than the quality level of service use recognized by the service user. In addition, it was found that the quality level of the provided service recognized by the service provider had a significant effect on the service provider's business satisfaction level but the quality level of service use recognized by the service user had not effect on the business satisfaction level of the provider.

We are concerned with whether a vertically integrated broadband and content provider can unreasonably advantage itself over competing content providers, either by selling quality-of-service (QoS) to content providers at unreasonably high prices, or by refusing to provide access to QoS to competing content. We address this question by modeling the competition between one such vertically integrated provider and one over-the-top (OTT) content provider. The broadband provider decides whether to deploy QoS, and if so it also determines the QoS price if sold to either the OTT content provider or directly to users. We analytically determine when the broadband provider will sell QoS and when the OTT content provider or users will purchase QoS. We characterize the optimal QoS and video service prices. The Internet service provider (ISP)'s market share increases with the difference in the value of the two video services and decreases with the difference in the corresponding costs. Numerical results illustrate the effect of QoS price on content price, the variation of prices and profit with QoS price, and the variation of prices and market shares with the benefit of QoS. The ISP may sell QoS to users at a lower price than when QoS is sold to the OTT provider.

International Roaming is a kind of telecommunication service that enables subscribers use the same mobile number when they go abroad and access other service provider's network. International roaming call is made through three network parts-home (original service provider) network, intermediate network, and local (overseas service provider) network. It is not possible to monitor every section of whole roaming service network because service providers do not provide their network management information to other service providers. The limitation causes harsh problem when a service anomaly arises and operators have to confirm the reason of failure. To solve this problem, we propose a scheme that deduces roaming service status of each overseas service provider using internal network management information. SK telecom implemented a international roaming service management system based on the scheme using performance measurement of signaling points, roaming service nodes, and charging data from existing network management systems.

대부분 기업들의 본사와 지사처럼 위치상으로 멀리 떨어져 있는 소속 네트웍들의 연결은 Service Provider를 통한 VPN을 이용한다. 트래픽이 대용량화되고 서로 다른 네트웍간에 보안도 중요한 문제로 부상하는 상황에서 기존의 Layer 2 또는 Layer 3 VPN의 단정을 보안한 MPLS-VPN의 적용은 Service Provider로서는 한 가지 해결책이 될 수 있다. Service Provider측면에서 MPLS-VPN기술에 대해 요약하고, Service Provider로서 백본을 제공, 운영하는 LG CNS에서 기존 고객사 네트웍을 MPLS-VPN으로 전환한 사례를 들어 실제 적용 방법을 소개하고자 한다.
