The present invention relates to a public telephone system and a service method thereof, and more particularly to a public telephone service using radio frequency identification (hereinafter referred to as "RFID") and a communication terminal (for example, a public telephone). It relates to a public telephone system and a service method thereof that can be used.

RFID is a radio frequency identification technology, developed in the middle of the 20th century and commercialized since the late 1990s.

The RFID refers to a method of identifying an individual product using radio frequency. If only an antenna and a tag are provided, RFID can identify information and insert necessary information without directly contacting a reader (or a reader). This is different in that the bar code is in direct contact with the laser reader to exchange the necessary information with the laser reader.

On the other hand, the RFID system consists of an RFID tag that can store data including a personal identification number, a reader that can read data in the RFID, and an antenna that transfers data between the RFID tag and the reader. Can be.

In addition, the RFID system may be classified into an inductively coupled method and an electromagnetic wave method according to a wireless access method. The mutual induction method is used at a short distance (about 1m or less), and coil coils are used to supply energy required for the operation of the RFID chip from the reader. Therefore, the antenna coil of the reader used in the mutual induction method generates a strong magnetic field in the surrounding area. On the contrary, the electromagnetic wave method is used for medium and long distances and includes a battery for driving the RFID chip because the energy required to drive the RFID chip is not supplied from the reader.

The RFID system may be classified into a low frequency RFID system using a 30 KHz to 500 KHz frequency and a high frequency RFID system using a 850 MHz to 950 MHz or a 2.4 GHz to 2.5 GHz frequency according to a radio frequency band used.

In addition, the size of the RFID chip used as an RFID tag ranges from an extremely small micro RFID chip of less than 1 mm to an RFID chip of 1 cm size with a built-in battery.

Such RFID systems are used in various fields such as inventory management, container / pallet / box management, automatic inspection, incoming and outgoing management, automatic sorting, rental product management, counterfeit identification, anti-theft, cargo and product tracking management. On the other hand, RFID systems have not yet been applied to public telephone network services.

Public switched telephone networks represent a set of voice-driven public telephone networks that are connected globally and include both commercial and state-owned networks. The public telephone network is a collection of circuit-switched telephone networks that have evolved since the days of the inventor of the telephone, Alexander Graham Bell. Today's public switched telephone networks are technically almost completely digital, with the exception of the end link from the telephone company to the user.

Public telephone networks actually provide the majority of long distance infrastructure with regard to the Internet. Internet Service Providers pay long-distance telephone companies, lease high-speed leased lines, and then use packet-switched schemes to allow many users to share their circuits, so that Internet users can see remote servers. Even if they approach, they do not have to pay long distance charges such as long distance or international.

There are two ways in which public telephone network services can be used.

The first is to set up and use a telephone in the home for a specific user, and the second is to use a pay telephone or public phone to pay for each unspecified number.

Home telephone is a line that connects a specific user, so each time you use the telephone, the service provider automatically calculates the communication fee based on the unit time and distance for the phone number and collects it when it reaches a certain period. On the other hand, since a public telephone is used by an unspecified user, there is a method of inserting a coin, deducting the balance recorded on a magnetic card, or charging through a credit card. This method also charges according to the coin reception signal sent from the telephone station whenever the unit time elapses according to the call distance.

By the way, in the case of using a public telephone, there is a difficulty in making a telephone call if the user has no coin or a place to purchase a telephone card.

In this case, the telephone call can be made through the toll free telephone, but it is inconvenient to know the additional number for making the toll free telephone and to obtain the consent of the toll free telephone.

In addition, due to the proliferation of mobile phones, public telephones are left in various places such as streets and underground walkways, thereby making public telephone infrastructure idle.

Therefore, the present invention was devised to solve the above problems, and by using a public telephone service using RFID and a public telephone, the user of the public telephone does not have to carry a coin or a telephone card, and the burden is on the receiver.
