How to charge public telephone charges using the main body display window

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless mobile payphone system installed in public transportation such as a taxi or a bus to provide a wireless communication service to the general public. The present invention relates to an additional method of using a public telephone fee using a display window of a mobile phone main body which calculates a mobile phone call fee on its own and displays it through a display window without installing a separate device.

Recently, thanks to the rapid spread of personal mobile phones, mobile wireless pay phones have been installed in taxis and buses. The use of wireless mobile payphones is expected to increase the frequency of use because it provides communication services at a relatively low price compared to the general personal mobile phones currently used.

However, since the mobile payphone installed in the vehicle has to install a billing machine for calculating and receiving a fee, an increase in mobile payphone construction costs and A / S problems occur due to the separate installation of the billing machine.

In order to solve this problem, the present invention can add a public telephone bill without an additional billing machine through the development of a program that automatically calculates the charge for using the telephone in the mobile payphone itself and displays it through the display window. I would like to propose a solution.

It is an object of the present invention to separately install an expensive billing machine, which is specifically required in a vehicle, to calculate the billing according to the use of a wireless mobile payphone system installed in public transportation such as a taxi or a bus to provide a wireless communication service to the general public. The present invention provides a method of charging a public telephone service fee using the display window of a mobile payphone main body that calculates its own mobile phone call charge in a mobile payphone main body and displays it through a display window on a public phone terminal. .

Features of the present invention include the steps of: performing a public network connection according to the dialing of a mobile public telephone, timing counting a talk time when a call establishment signal is received following reception of a network connection signal from the exchange side; When the call completion signal is transmitted from the exchange side during the call time count of the present invention is a method of charging a public telephone usage fee using the display window of the phone body comprising the step of calculating the charge for the corresponding call time and displaying it.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 schematically shows a hardware block diagram of a mobile payphone main body for explaining the present invention, which is substantially the same as the hardware configuration of an existing general personal mobile phone. As referred to herein, the mobile public telephone system converts and outputs the RF signal received through the antenna into a digital signal, and modulates the encoded digital voice signal input through the encoder into the RF signal and transmits it to the outside. RF module 12, a decoder 16 for decoding and outputting a digital voice signal output from the RF module, and processing digital information of the decoder to transmit to a vocoder (VOCODER) 20 and digital from the vocoder. A processor 10 for processing voice data and transmitting it to the encoder 14, which is a data encoding apparatus, a memory 18 in which a basic operating program of a mobile phone is stored, and a display 26 for displaying public telephone call time and usage fee And a key input 28 for selecting dialing and other telephone functions, and a microphone 22 and a speaker 24.

The operation process of the mobile payphone having such a block configuration is as follows.

First, when the desired telephone number of the other party is keyed in through the key input unit 28 provided in the main body of the mobile payphone, the corresponding telephone is processed according to the data processing of the memory 18 having the inter-block data and the system program by the processor 10. The number is transmitted to the exchange side of the mobile telephone operator through the encoder 14 and the RF module 12.

Accordingly, when the call connection is made, the voice signal of the oscillator through the microphone 22 is converted into a digital signal to the vocoder 20, encoded by the encoder 14, and then transmitted to the exchange side via the RF module. Therefore, the sender's voice signal is transmitted to the counterpart terminal connected to the exchange side.

Similarly, the signal received by the RF module 12 from the counterpart terminal through the exchange side is frequency-converted by the RF module 12 and output as a digital value of the signal converted from the carrier signal.

The digital signal output from the RF module is decoded by the decoder 26 and then input and processed by the processor 10. The digital voice signal processed by the processor is converted into an analog signal while passing through the vocoder 20 and output to the speaker 24.

The operation of such a mobile payphone will be described in detail with reference to FIG.

In order to use a mobile payphone installed with public transportation such as a taxi or a bus, the mobile payphone is in a standby state for outputting a dial tone.

In this state, when the other party's telephone number is input using the key input unit 28 of the main body of the telephone, the mobile public telephone system attempts to access the network through the exchange side of the mobile communication service provider according to the above operation process.

When the network connection is made following the execution of the network connection attempt step, since the network connection confirmation signal (Alert 1) is transmitted from the operator's exchange side to the public telephone main body side, the processor 10 of the mobile public telephone main body It is determined whether network connection is successful.

When the network connection is confirmed by the execution of the above step, receiving a confirmation signal (Alert 2) for determining whether a call is established or not, the call time is counted (C). In other words, the timing count is executed from the start of the call.

In the next step, the processor in the main body checks whether the call is interrupted at a predetermined time period and continuously accumulates the timing count (C = C + 1) when the call is in progress.

On the other hand, when the use of the mobile payphone is terminated, the exchange side generates a call termination confirmation signal (Alert 3), and when such a signal is received at the payphone terminal, the processor calculates a usage fee for the talk time and displays the display 26. Is displayed.

Accordingly, a passenger using a mobile payphone mounted on the transportation means pays the usage fee displayed on the display of the terminal. The usage fee displayed on the display window of the mobile public telephone terminal is continuously stored in the memory for management and accumulation thereof.

As described above, the present invention does not require the installation of a separate billing machine for imposing a charge for using a public telephone on a public transportation device in which a mobile wireless public telephone is installed. And increase the installation cost can be solved.
