Description

Description: TECHNICAL FIELD The present invention relates to a mobile terminal for leasing, and more particularly to a mobile terminal for leasing in which mobile terminals are lent to unspecified persons and used in public mobile communication.

[Conventional technology]

Conventionally, there is a mobile public terminal as another use of the mobile terminal. When the user uses the mobile public terminal, the user inserts a coin into the billing storage mechanism and then dials it.

[Problems to be Solved by the Invention] However, as described above, the conventional mobile terminal cannot be used unless coins are prepared, or the charging storage mechanism has a limit in size and is used continuously for a long period of time. In terms of weight, it was inconvenient to carry.

The present invention has been made in view of the above points, and in a system in which a mobile terminal is used by another person, a communication fee of a user is paid in advance, and a mobile terminal for leasing that can be used freely up to that amount is provided. Aim.

[Means for solving the problem]

 FIG. 1 shows a principle configuration diagram of the present invention.

In FIG. 1, when inputting a communicable amount paid by a user, a leasing mobile terminal is provided with a password input unit for inputting a predetermined password, a password input by the password input unit, and a pre-stored password. Password authentication means for comparing and authenticating the password, and storage means 1 for storing the amount of communication possible previously paid by the user authenticated by the password authentication means, and calculating and accumulating a communication charge during mobile communication. Accumulating means 2, a display means 3 for displaying the accumulated amount obtained by the accumulating means 2 or a difference between the communicable amount stored in the storage means 1 and the accumulated amount, and a storage means for storing the accumulated amount. The problem is solved by having communication disconnection means 4 for disconnecting the mobile communication when the communicable amount stored in 1 is exceeded.

[Action]

When lending the terminal to the user, the communicable amount is received from the user in cash or a telephone card, and only the terminal in which the communicable amount is input is lent to the user, and if the integrated communication fee becomes larger than the fee paid in advance by the user, the communication is performed. Be cut off. Further, the accumulated communication fee is displayed on the terminal to inform the user how much communication can be performed later. Further, the calculation of the communication fee can be performed by the mobile terminal independently of the exchange.

〔Example〕

FIG. 2 is a block diagram of a terminal according to an embodiment of the present invention. 2 corresponds to the storage means 1 in FIG. 1, the charge index calculation memory 107 and the accumulated communication charge memory 108 correspond to the accumulation means 2 in FIG.
1 corresponds to the display means 3, and the control unit 103 and the telephone unit 104 correspond to the communication disconnecting means 4 in FIG.

When lending a mobile terminal to a user, first, a fixed amount is written in the communicable amount memory 101 in FIG. 2, and the amount is received from the user by cash or a telephone card or the like.

The input of the amount is performed by connecting another computer (not shown) or a dedicated input device from the external terminal 102. The input interface from the external terminal 102 of the control unit 103 is not disclosed, so that it is impossible to input the communicable amount without permission. In this embodiment, the external terminal 102
Input example, but not the external terminal 102 but the telephone unit 1
There is also a manual input method from 04. In this case, the telephone
You can also do this from the dial attached to the 104.

The operation at this time is shown in the flowchart of FIG. The password is stored in the control memory 105 in advance (step 32), and a special identification number is dialed or a special switch is pressed (step 33). Indicates to the control unit 103 that this number is not a dialed number for performing communication (step
34), and input a predetermined password (step 35).

If the password preset in the control memory 105 and the password entered in step 35 are the same,
The process proceeds to step 37, and if not, the process proceeds to step 35 (step 26).

A message prompting the user to enter the communicable amount is displayed on the display unit 109 or the telephone unit 104 is notified by voice or tone (step 37). Next, a communicable charge is inputted from the dial section (step 38). By keeping the password secret without using the external terminal 102 as described above, unauthorized input of the communicable amount can be prevented. Only the terminal for which the communicable amount has been input is lent to the user. When using the terminal to which the communicable amount has been input, the user dials the other party's dial number from the telephone unit 104 in the same manner as a normal mobile terminal of the user. The dialed number is the control unit 10.
The data is accumulated in step 3, transmitted from the transceiver 106 to a wireless base station (not shown), and connected to a general public telephone network via a mobile communication exchange under the same control as a normal car telephone to perform communication.

When the communication starts, charging starts not only at the exchange but also at the mobile terminal.

The billing method at the mobile terminal requires a talk time and a charge index. According to the current signaling system with the radio base station of the mobile phone, the radio base station always sends the radio base station number, so that the radio zone of the mobile terminal can be known. A list for calculating the charge index from the wireless base station number and the dialed telephone area code is stored in the charge index calculation memory 10.
By having it at 7, the price index can be easily obtained.
As a result, at present, there are public telephones used by an unspecified number of users in automobile telephones, but if this signaling method is used, it is possible to directly inform the exchange of the toll index.

 A flowchart during the communication is shown in FIG.

 A wireless base station number is received (step 40).

A dial number from the mobile station is obtained (step 41), and a charge index is calculated from the charge index calculation memory 107 (step 4).
2). If the communication is started, the process proceeds to step 44, and if the communication is not started, the process proceeds to step 49 (step 43). The control unit 103 charges based on the fee index.
At this time, the charge does not need to be the same as the value charged by the exchange, and may be a value to which a profit for leasing is added. In addition, with current car phones, 6.5
This is a distance-based time difference method in which 10 yen is charged every second and 4.5 seconds. However, a fixed amount of charge can be added to each communication (step 44).

The charged amount is added to the integrated communication charge memory 108 every time the charge is made, and the total amount is compared with the value of the communicable amount memory 101 (step 45). Available communication amount memory 10
If the value of 1 is larger than the value of the accumulated communication charge memory 108, the communication is continued as it is, but if the value of the accumulated communication charge memory 108 is larger, the communication is disconnected. At this time, all the fees paid in advance by the user have been used.

Available communication amount memory 101 and accumulated communication charge memory 1 during communication
By always displaying the difference between the values of 08 on the display unit 109 (step 46), the user can know how much more communication is possible. In addition, if the value of the display unit 109 becomes small, it is notified by voice or tone so that sudden disconnection during communication can be prevented.

If the communication is disconnected, the process proceeds to step 30. If the communication is continued, the charging time is determined in step 48, and if the charging time is reached, the charging is integrated in step 44 (steps 47 and 48).

When the value of the communicable amount memory 101 is larger than the value of the accumulated communication charge memory 108, when the lease terminal is returned, the difference is returned to the user.

In the above embodiment, it is assumed that a predetermined amount is paid in advance. However, only the amount is set in advance, but when lending to a reliable user, the used amount is paid later. You may.

〔The invention's effect〕

As described above, according to the present invention, it is possible to provide a mobile terminal of a portable size that can be used by an unspecified number of people because no coin is used. In addition, the communicable amount can be set in exchange for the fee at the time of lease, so that the fee is not paid. The user also sees the difference between the accumulated amount and the communicable amount, so that the user can always check how much communication can be done, improving serviceability. On the other hand, the mobile terminal can calculate the communication charge independently of the exchange, so the lease charge Can be charged in addition to the communication fee, and is effective when another person uses the portable terminal.
