The present invention relates to an unmanned and self-contained multi-function public telephone, more specifically, a plurality of roadsides and indoors are installed, the basic voice call through the telephone network and VOIP voice call through the data network user's selection and distance, call charges, etc. It can be selectively executed in consideration of the user's consideration, and data can be uploaded / downloaded from a laptop or the like through a wired port. A multifunction payphone.

As is well known, the telephone is the most representative apparatus of the communication means. Telephones can be divided into home telephones, corporate key phones, and public telephones that can be used by ordinary users. In recent years, telephones are emerging from the conventional telephone functions as simple telephone equipment, and more efficient and convenient functions using a microprocessor are being added to the telephones. Among these, public telephones are installed for general users by telephone service companies, and have been limited to conventional call functions.

Meanwhile, with the recent development of office automation equipment, facsimile machines, printers, modems and scanners have been widely distributed to general users, thereby providing work efficiency. These office automation devices are usually used in homes or offices, and are developed and marketed as separate products due to the characteristics of each device.

However, as the scope of work using office automation equipment increases day by day, the purchase of each of these devices individually is an economic burden for the general consumer. Multi Function Peripheral (MFP) is being developed and marketed. Typically, such a multifunction device is used in conjunction with a computer, it is possible to selectively install and use a variety of products depending on its use.

By the way, according to the conventional office automation equipment, when purchasing each device individually or when purchasing a multifunction device in which each device is a systemized, the size of the corresponding product is not available because it is portable. However, in recent office environments, various types of information must be transmitted / received or output from the outside.

Recently, portable computers (laptop computers, palm-top computers, PDAs, etc.) are commercially available, but these computers only perform functions of pure computers and require separate equipment to carry out functions such as communication and output. . As a result, there is a need for users to use various office equipment even in unspecified areas.

In addition, due to the development of high-speed information communication, the use of the Internet has been commercialized, and various and more informations are rapidly provided through the Internet in all fields. In addition, the high-definition video communication is possible so that the user can make a call while viewing the other party through the screen. Such a high quality service is indisputable that the network foundation of high-speed information communication such as optical communication or xDSL is mainly composed.

However, in the conventional wireless communication method, as shown in FIG. 1, since the basis of the communication network is wireless, customers having wireless terminal devices such as mobile phones, PDAs, tablet PCs, etc., require high-speed data communication such as video calls. There is a variety of information that is not properly provided, and although the Internet service provided by some mobile carriers is possible, it is inevitable to provide a low-quality service.

That is, the conventional communication network configuration is a digital cellular communication network for providing a voice level service. When a user having a wireless terminal apparatus requests a service, the mobile communication network provides a service by linking a wired or wireless network through a base station. It is almost impossible to provide high-speed data communication service because the wireless network base including the base station, etc. is composed of voice-based digital cellular communication network.

As a result, in order to provide high quality high-speed communication service, a service provider must establish a new base station or upgrade an existing base station and establish a wired communication network such as an optical cable. You have to suffer huge financial losses.

In other words, not only is it difficult to select a place (for example, a department store) due to the establishment of a base station having a simple function of wired or wireless relay, but also a huge cost is required when upgrading an existing base station. do.

In addition, users of public telephones (PSTN) also have to make international calls urgently through public telephones because services such as VOIP, which can make inexpensive calls through data communication networks, are not installed in conventional public telephones. In this situation, there is a problem that international calls are made at relatively high rates, and other mobile communication devices such as mobile phones also have a problem that the rates are much higher than VOIP services for making voice calls through the Internet. However, in the conventional system, it was not possible to use such VOIP service on the roadside and indoors.

In addition, many public telephones have a problem in that a huge maintenance cost is wasted just by maintaining an already installed public telephone because its function is only a simple voice call. In addition, recently, various wireless communication devices capable of short-range wireless communication have been released. However, a separate short-range wireless relay device must be installed to form a zone capable of short-range wireless communication. If installed on the roadside and indoors, there was also a problem that consumes enormous costs.

The present invention has been made in view of the above-described prior art, and many of them are distributed on the roadside and indoors, so that the basic voice call through the telephone network and the VOIP voice call through the data communication network are considered by the user's selection, distance, and call charges. It can be run selectively, and can download / download data from laptops through wired / wireless ports, and unmanned and self-sufficient type for short-range data communication to a large number of wireless communication devices through wireless ports.
