The present invention relates to a personal information terminal using a wireless call signal.

More specifically, by using a wireless call system that is currently operating and a personal information terminal capable of receiving a wireless call signal, various types of information such as large data, graphics, still images, and voices can be received and used on its own large display and external peripheral devices. It relates to a personal information terminal using a radio call signal to output.

In general, wireless calling refers to providing a service such as a beep, a number, and a letter to a specific person (subscriber) carrying a wireless call receiver (beep) as a kind of mobile communication method.

Wireless terminals are used to call people on the move. In the early days, wireless calls only generated the ringing tone. However, the wireless terminals are being developed and are rapidly changing from text-based numbers such as phone numbers to text services. Life information services such as sports events are provided.

Way is being introduced.

In addition to wireless wireless terminals, mobile communication devices include a beeper with a calling function such as a public payphone and a mobile phone (CT-2) complementary to each other, and is a common frequency communication device used for taxi calls or truck logistics. (TRS), a mobile phone that is used by the general public regardless of the place, and a personal mobile communication (PCS) capable of transmitting multimedia such as voice, data, and video.

Among the kinds of mobile communication devices, the wireless wireless terminal (beep beep) is a relatively simpler system than other mobile communication systems, and has a relatively excellent reception rate compared to the low usage fee, and has the characteristics of being able to receive calls without being disturbed while doing other work. have.

The biggest advantage is that the pager (Beeper) is small and the service fee is lower than other mobile communication means.

However, the current wireless wireless terminal cannot receive long sentences data due to the limitation of the storage capacity and display space in accordance with the miniaturization of the device itself in receiving information, so it is possible to use only limited letters and numbers, voice and video, etc. In order to receive a separate additional system has to be installed, so a large amount of new investment in the facility, there was a problem that the cost increases.

Therefore, an object of the present invention is to receive a large amount of data, graphics, still images, and voice information using a wireless call system and a personal information terminal capable of receiving a wireless call signal. Its purpose is to connect with peripheral devices and provide various information.

2 is a perspective view illustrating an input-output relationship between a personal information terminal and a peripheral device using a wireless call signal according to the present invention.

As shown, the personal information terminal 100 receives the high frequency radio call signal emitted from the base station antenna (not shown in the drawing), analyzes the transmission contents of the radio caller, and outputs the result to the personal information terminal 100 itself. The display unit 29 can be displayed on the mounted display unit 29. Here, the data transmitted to the radio call signal includes voice data, large-capacity text data, and graphic image data along with a call signal that forms a simple combination of letters and numbers as in a general pager, which includes POSAG, By using protocols such as FLEX, ERMES, and APOC, it is possible to provide a large amount of data such as learning papers, academic journals, or announcements at a low communication cost, rather than a small amount of data. In more detail, a large amount of data can be transmitted by continuously transmitting a message block in the data packet structure used in the above-mentioned wireless calling protocol. To this end, the personal information terminal 100 of the present invention has a memory 30 as a large-capacity storage device to store a large amount of information so that the conventional wireless terminal 11 can store a large amount of information that cannot be used due to the small capacity of the system. It is preferable that the control unit 28 is also composed of a control chip, such as a microcomputer having a predetermined central processor function for storing and processing text, graphics, audio data.

Next, the operation of the present invention will be described in more detail. A service provider who provides a service using a wireless call signal or a person who needs to transmit data during an idle period of a network uses data in a wireless call signal using a predetermined wireless call system. Is transmitted from the base station transmitting the radio call signal. The signal transmitted from the above-described base station is received by the radio call signal receiver of the interpersonal information terminal D 100, down to low frequency, demodulated, and transmitted to the controller 28. The control unit receiving the data transmitted from the radio call receiving unit stores the received data in a memory in a predetermined format and simultaneously displays summary information about the data on a display unit configured in the personal information terminal 100. After confirming this, the user transmits a predetermined key input signal to the control unit 100 through the key input unit and outputs the received data to the display unit 11 or through the computer, TV receiver, printer, and modem through an output unit connected to the control unit. Output

The process of transmitting the received data to an external device is performed by the user using a selection command key of an external output device configured in the key input unit 34 or by selecting a menu outputted in the form of a menu bar of the display unit 11. 100) Data is output to the outside.

First, when a function key or a menu bar for outputting data to a computer is selected, the controller calls the stored data from the memory 30 and transmits the stored data to the output unit 32. The output unit 32 that receives the data transmitted from the control unit 28 converts the digital signal recognized by the computer into a video / audio signal conversion unit for computer transmission provided in the output unit to convert the video input unit and audio input of the computer. And the data received by the speaker as the audio output unit configured with the computer monitor.

When a separate printer is provided, the above-described output unit includes a printer output unit having a communication setting and a data format for processing data in a predetermined printer. The printer output unit converts the data transmitted from the control unit 28 into a form that can be recognized by the printer and transmits the data to the printer.

Next, in the case where it is desired to transmit the received data to a remote computer, a printer or a voice extractor via a telephone line, the output unit receiving the data from the controller transmits the received data to the modem. The modem receiving the data converts the digital signal into an analog signal and transmits it to the remote place through the PSTN network. The above-described modem converts the data format recognized by the personal information terminal 100 into an analog signal and performs a conversion in the physical layer in order to perform a function such as using a modem in a general PC.

The external output described above is the greatest feature of the present invention. An additional function of the above-described personal digital assistant is a function of receiving broadcasted data. For this purpose, the cap code, which is an identifier, can be used in the same manner for each operator. General study paper companies, newspaper companies, and life information providers can implement blogcasting, which is one-to-many communication, by providing identifiers with different cap codes to users receiving their services.
