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

1 is a circuit configuration diagram of a hardware device of a wireless mobile public telephone system in a commercial vehicle using a personal mobile phone for carrying out the present invention.

As referred to herein, the wireless mobile public telephone system using a mobile phone is composed of a mobile phone main body 30 and a handsfree kit 40.

The mobile phone main body 30 of the mobile public telephone system selects and converts the RF signal received through the antenna into a digital signal, and modulates the encoded digital voice signal input through the encoder into an 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. The mobile phone processor 10 which processes the voice data and transmits it to the encoder 14, which is a data encoding apparatus, a memory 18 in which the basic operation program of the mobile phone is stored, and a display for displaying the time and cost of a public telephone call ), A key input 28 for selecting dialing and other remaining functions, and a microphone 22 and a speaker 24.

The handsfree kit 40 is connected to the handsfree processor 42 and an interface device 46 for interfacing data and voice signals between the mobile phone processor 10 and the handsfree processor 42 for use of a mobile public telephone. It includes a charging indicator 44 for displaying the charge according to, and the charging circuit 48.

The operation of the mobile payphone using the cellular phone having such a block configuration will be described in detail based on the hardware configuration of FIG. 1 and the flowcharts shown in FIGS. 2 and 3.

First, when the desired telephone number of the other party is keyed through the key input unit 28 provided in the mobile phone main body 30 of FIG. 1 having a mobile payphone function, the data processing system and the system program of each block by the mobile phone processor 10 are inputted. According to the data processing of the memory 18 having a corresponding telephone number is transmitted to the exchange side of the mobile telephone operator through the encoder 14 and the RF module 12.

Accordingly, when a call connection is made, the voice signal of the caller through the microphone 22 is converted into a digital signal in the vocodo 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 16 and then input to the processor 10 for processing, and the digital voice signal processed by the processor is converted into an analog signal while passing through the vocoder 20 and then a speaker ( The output will be 24).

In the hands free kit 4, the hands free processor 42 connected to the mobile phone processor 10 through the interface device 6 displays the talk time and the corresponding call charge on the charging indicator 44.

If the anti-theft function of the mobile phone is selected in the initial state of the mobile phone public telephone system operating in this way, an alarm is issued from the mobile phone body upon disconnection by checking whether the hands-free connector is disconnected.

As shown in FIG. 2, in the standby state or the call state, the mobile phone microcomputer determines whether the handsfree kit and the main body of the mobile phone are connected to the connector, and when the connection is disconnected (connector disconnected), the call is forcibly terminated and an alarm sounds.

The alarm sound is designed to be released only by a specific key input registered and registered in advance, and the alarm sound continues to be generated in the mobile phone until a certain key input signal is received.

That is, when a passenger or an intruder in the taxi separates the mobile phone main body 30 from the handsfree kit 40 and moves to the outside, the mobile phone coupled to the interface device 46 of the handsfreekit set is shaken from the handsfreekit. In this case, the processor 10 of the mobile phone recognizes the alarm.

On the other hand, when the cellular phone is opened in the initialization of the cellular phone public telephone system, the cellular phone processor determines whether the emergency phone selection mode is selected, prohibits the calculation of the call charge in the emergency phone mode, and terminates the emergency call by the emergency call subroutine.

However, if the emergency call mode is not selected at this step, it is determined whether the first program execution mode programmed in the mobile phone, that is, the mode capable of transmitting / receiving at all times regardless of the presence or absence of a wired interface connection between the mobile phone and the handsfree kit.

Here, if the first program execution mode is registered in the mobile phone, the communication mode of the mobile phone is set to a mode capable of transmitting and receiving at all times and then it is determined whether the public phone mode.

On the other hand, if the first program execution mode is not determined in the first program execution mode, the second program execution mode restricts the transmission function of the mobile phone when the handsfree kit and the mobile phone are separated.

When the separation of the handsfree kit and the mobile phone is detected in the second program execution mode, the transmission function of the mobile phone is restricted, the differential charge mode of the basic fee is selected, and the use of the public telephone is determined. When the mobile phone is used as a general personal mobile communication mode, it is determined whether to use the public telephone by going to the display mode of use time and fee according to the call connection.

In the public phone mode, the redial function is deleted if the public phone mode is used in determining whether the public phone is used by the signals coming through the three paths, and if there is a SEND key input followed by the key input, dialing to the corresponding number is performed. By deleting the telephone number data entered immediately before, the possibility of infringement of the personal privacy of the public telephone user is excluded.

In the use of a public phone, the call charge according to the talk time is displayed in the billing machine provided in the hands free kit 40. At this time, the hands free kit processor 42 accumulates a continuous call charge by one person and displays it. do. This cumulative amount of money can be deleted by a reset key input.

In addition, if there is a recent call information display key input following the charge accumulation display, the time and charge accumulation information for the last 10 calls, for example, processed according to a program set by the processor is output.

The present invention as described above is a transmission and reception restriction function, anti-theft function, automatic deletion of the last dial number, continuous call time and charge accumulation function and mobile phone operation mode in a public telephone system using a personal mobile phone installed in a taxi By assigning a differential fee application function for each selection and operation mode, a unique effect of convenience of passengers using a commercial vehicle and call management by a mobile phone type wireless public telephone manager is shown.
