B-ISDN is expected to be a main vehicle of future telecommunications. There has been a series of studies on the demand and the market prospect of B-ISDN services. It is true, however, that they lacked some economic reality since the price of services has been overlooked which is a critical economic factor. In this study, we analyze some aspects of the tariff system of B-ISDN services. First, we explore and summarize the billing parameters of B-ISDN services from diverse characteristics of services and ATM network. These parameters are essential if the services are to be charged based on usage. Secondly, we discuss what factors be considered in the design of B-ISDN services tariff systems from various points of view such as traffic characteristics, information types and connection types, etc. The results of this study will offer fundamental insights in the design of B-ISDN services pricing scheme and provide references for efficient services providing.

In this paper, the affecting factors of the access demand for the cellular service are derived, and the access demand function of the cellular service is estimated. The results obtained in this study are as follows: First, the price(access charge) and the income elasticities of cellular services are higher than those of PSTN. Second, like other telecommunication services there exists a network externality in cellular communication services. Third, the technological capability of the service provider has played an essential role in expanding the size of subscribers. Fourth, the access demand of cellular communication service is not sensitive to the usage charge. According to the above results, it can be inferred that if the access charge is lowered, the number of subscribers will increase to the critical mass, and then the cellular communication market will grow up to a saturation point naturally.
