Mobile services with handset bundling and governmental policies for competitive market

Governmental policies can significantly affect the social adoption of services offered by communication technology providers and competition between service providers. Following the implementation of several policies by the Korean government and mobile network operators’ promotion of mobile handset bundling, consumer adoption rates of the latest mobile phone and communications services have been higher in Korea than in other countries. Mobile handset bundling provides consumers the bundled sale of mobile phones and services, but this practice can restrict consumers’ choice of services and limit competition among service providers. This study analyses this ambivalent effect of bundling by mobile network operators (MNOs) and evaluates the outcomes of the Korean government policies (2011–14) using market statistics. Our results highlight that the policies have produced changes in market share but the government needs to promote service differentiation among providers.

Parlay/OSA与Web服务的技术融合及其商业应用

在传统电信网络中,电信业务及其应用主要通过智能网等集中式智能网络技术实现,通常部署在各电信运营商通信网络内部。近年来,随着互联网的飞速发展以及人们对新型业务需求的不断增加,电信运营商必须将其业务部署与承载网络分开,以向更多业务提供商开放其通信网络,让第三方能够以可管理、可计费、安全的方式参与到电信业务的开发过程中。正是这种需求的刺激,推动了Parlay/OSA规范的制定和发展。文章从体系架构角度,分析Parlay/开放业务访问(OSA)和Web服务(Service)两种技术,比较两者在目标功能实现及其与外部应用交互方式上的异同点,并基于此提出了两种技术融合路线,最后介绍3种典型的ParlayWebService商业应用模型。     

Building Grid Portal Applications From a Web Service Component Architecture

This work describes an approach to building Grid applications based on the premise that users who wish to access and run these applications prefer to do so without becoming experts on Grid technology. We describe an application architecture based on wrapping user applications and application workflows as Web services and Web service resources. These services are visible to the users and to resource providers through a family of Grid portal components that can be used to configure, launch, and monitor complex applications in the scientific language of the end user. The applications in this model are instantiated by an application factory service. The layered design of the architecture makes it possible for an expert to configure an application factory service with a custom user interface client that may be dynamically loaded into the portal.     

An agile server for cross-provider service peering and aggregation

Telecommunications and next-generation network IP-based services can be increasingly delivered at network edges and in peered third-party networks. As a result, subscribers bypass operators' services in favor of alternative novel services; accordingly, potential revenue is lost. By bundling existing viable network-based services across providers, however, service providers can create new revenues and avoid further erosion of their market share. Business announcements attest to this growing trend, but thus far cross-provider solutions take the form of point-to-point customized integrations. In the emerging service delivery paradigm, providers must be able to interwork fluidly with partners already operating profitable services, and do so without going through the risky and costly service development cycle, and without the need for extensive customized software development. We outline an intelligent-agent-based service peering and aggregation server whose deployment on service provider networks enables such interworking.

The EMA system: a CTI based e-mail alerting service

The integration of Internet services and telephony services is a new area for the development of telecommunications services. One example is an e-mail alerting service that uses the telephony network for e-mail notification. The EMA system is a computer telephony integration (CTI) application that checks a user's mailbox on the mail server and informs him/her over the phone when new e-mail arrives, eliminating the need for permanent Internet connection. The EMA system has a Web-based interface, enabling the user to configure service parameters. The EMA system is developed as a distributed and concurrent application. It consists of seven modules: the console, Web interface, Web handler, controller, voice machine, database, and mail checker, using communication solutions based on component object model (COM) technology. This article describes the structure of the EMA system, its implementation, and advantages for users     

Over-the-top bundled services in the Korean broadcasting and telecommunications market: Consumer preference analysis using a mixed logit model

Platform service providers in Korea and worldwide have launched over-the-top (OTT) bundled services, which increase market competitiveness. Forecasting the market expansion strategies of these providers can thus shed light on their future actions and influence government policies. In this context, this is the first study to analyze consumer preferences for bundled pay-TV and OTT services. However, due to a lack of market data availability, we conducted a discrete choice experiment and analyzed the marginal utilities of attributes using a mixed logit model. The results demonstrate that consumers expect an additional discount for pay-TV services when bundled with OTT services and that the more bundled services they currently use, the less sensitive they are to the discount rate. Furthermore, we found that OTT and TV broadcasting services have a complementary, rather than a substitute, relationship. Finally, according to a simulation analysis for the Korean broadcasting market, bundling OTT services to expand the market share of pay-TV service providers was largely ineffective.     

一种Web服务综合描述模型

Web 2.0时代,人网交互的便捷赋予了Web服务更多的社会化特性(如评分、评论等),却往往被服务的提供者忽视,导致难以有效实现基于用户体验的服务推荐。针对不同的用户视角,该文提出了一种Web服务综合描述模型,以多视图的方式集成Web服务的技术属性(如操作、消息等)和社会化特性。首先,从逻辑设计的角度出发,给出了其概念模型;然后,从工程应用的角度出发,构造其元模型,指导具体模型的设计;最后,根据一个应用案例,验证了方法的可行性。该模型和相关工具将为实现服务超市中服务的主动推荐奠定基础。

A2thOS: availability analysis and optimisation in SLAs

Information technology (IT) service availability is at the core of customer satisfaction and business success for today's organisations. Many medium‐ to large‐size organisations outsource part of their IT services to external providers, with service‐level agreements describing the agreed availability of outsourced service components. Availability management of partially outsourced IT services is a non‐trivial task since classic approaches for calculating availability are not applicable, and IT managers can only rely on their expertise to fulfil it. This often leads to the adoption of non‐optimal solutions. In this paper we present A ²thOS , a framework to calculate the availability of partially outsourced IT services in the presence of SLAs and to achieve a cost‐optimal choice of availability levels for outsourced IT components while guaranteeing a target availability level for the service.
