This paper examines when a consumer in existent telecommunication 2G applies to new telecommunication service 3G from the viewpoint of an option pricing theory. To improve telecommunication quality of service, the consumer applies to 3G. The application means an exchange of 2G for 3G with extra costs such as searching and conversion costs. Since the option to exchange is a right that the consumer can exercise or not, application to 3G is deemed an exercise of the option to exchange at most suitable value of the option. The timing to exercise the option depends on the extra costs and the additional communication benefit from new telecommunication quality of service. These affect an optimal timing to apply to 3G. The optimal applying or switching timing to 3G is when an economic value of the option to exchange is equal to an economic value of the extra costs plus the additional telecommunication quality from new telecommunication service. The option analysis used in this paper is applicable to various industries.

Broadcasting telecommunication convergence service means a service where broadcasting and telecommunication converge. Recently with the advancement of technology, broadcasting telecommunication convergence service has been evolving to provide multimedia contents through various devices including wired and wireless network environment. Up to now, IPTV and smartphone-based convergence services have been dominant, but more developed and evolved technology and media will appear in the future. In order to derive the next generation broadcasting telecommunication convergence service supporting model, this study derives an evaluation model of broadcasting telecommunication convergence service and presents a case of evaluation of 30 demonstration projects supported by the Korean government from 2010 to 2014. In this study, we derive an evaluation model and evaluate the demonstration projects by reflecting the position of the main stake holders of service such as users, experts, and related organizational institutions, away from the existing simple service evaluation method. Expert questionnaire used AHP (Analytic Hierarchy Process) method, and the evaluation results were divided into upper and lower groups to provide key implications by a gap analysis. From this analysis this study suggests guidelines for next generation broadcasting telecommunication service support projects. The next generation broadcasting convergence service business should be based on open platform type in terms of service type. In terms of service media, it should be centered on open devices such as smart phones and smart TVs. In terms of types of business responsibilities, it should be led by public organizations and it is necessary to increase the fund matching ratio by at least 62% when the private sector participates.
