The present invention relates to a local / international / international public telephone communication system suitable for second and third period carriers and resellers, a control method thereof, and a multimedia public telephone terminal. Third-party carriers and resellers can provide both long-distance and international public telephone services, including local public telephones, by an optimal system constructed using the general telephone lines of the first-period carriers with local telephone networks. The present invention relates to a local / international / international public telephone communication system suitable for second and third period communication operators and resellers, and a control method thereof and a multimedia public telephone terminal used therein.

With the development of new communication technologies, the opening of the telecommunications market and the introduction of competition in the telecommunications industry, a large number of international and long-distance telecommunications operators have emerged, and the environment of fair competition among operators has become more important, but the current local telephone exchange There are many cases where the technological competition in the environment is hampering the process competition environment.

In other words, many Telecommunication operators and service resellers, except KT, which monopolize the existing local telephone exchange network, provide public telephone services. For example, if a second service provider wants to provide local, suburban, and international public telephone service for its customers, it lacks the technical limitations and functions of the existing local telephone switching network, and the exclusive telecommunication line facility of Korea Telecom, the dominant service provider. Many problems are caused by the provision.

Currently, Korea Telecom public telephone service provides a service by connecting a local telephone line terminal (a charging pulse supply function for intercity, long distance, and international call charging) and a public telephone terminal of a local telephone exchange.

There are many problems, such as enormous additional investment costs such as new standard establishment and function enhancement.

Due to such technical limitations and enormous investment costs, the 2nd, 3rd term telecommunications operators and service resellers, except KT, the dominant telecommunications operator who have a local telephone network, are able to make local, intercity and international calls. Due to the impossibility of providing telephony service to its customers, it is being suggested as a representative case of impeding fair competition.

Due to this technical problem and such difficulties, the second and third period telecommunications operators have built their long-distance and international telephone exchanges and terminals through expensive leased lines, so that they are separated from local telephone exchange networks and are not able to interwork. It is not possible to make local calls from our public telephones, but it is inevitable that the overlapping investment of huge investment costs is inevitable when building a unique communication network for many operators and economic difficulties due to the difficulty of maintenance, etc. Many problems have arisen in the implementation of the service, which causes many difficulties in business development.

Accordingly, the present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a service provider for a first period telecommunications carrier in which second and third period telecommunication operators and resellers who do not have a local telephone network have a local telephone network. Local / international / international public telephone communications, suitable for second and third-term carriers and resellers who can provide both long-distance and international public telephone services, including local public telephones, by means of an optimal system configured using a regular telephone line. It is to provide a system and a control method thereof.

In addition, another object of the present invention is to display a public phone display of additional information such as various news, weather forecasts, local time information, etc. of the other country (including the region) that is beneficial to the user using the public phone using the called country code or area code To provide a multimedia public telephone terminal and its additional service operating method that can be provided through.
