Abstract

PURPOSE:To use the mobile terminal equipment freely up to a prepaid monetary amount by receiving a communication available monetary amount from a user when the terminal equipment is leased to the user and leasing only the terminal equipment whose communication available amount is entered to the user without use of a coin. CONSTITUTION:A mobile terminal equipment for lease is provided with a storage means 1 storing a preset communication available monetary amount, an integration means 2 calculating and integrating a communication charge at mobile communication, a display means 3 displaying a difference between the integration monetary amount and the communication available monetary amount stored in the storage means 1 or the integrated mount obtained by the integration means 2, and a communication interrupt means 4 interrupting the mobile communication when the integrated monetary amount exceeds the communication available monetary amount stored in the storage means 1. Since no coin is required for the communication, a mobile terminal equipment with a size enabling portable configuration end used by lots of unspecified persons is realized and the communication available monetary amount is set in replacement with the charge at lease. Thus, an unpaid charge is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a leased mobile terminal, and particularly to a leased mobile terminal that is used by being lent to an unspecified person in public mobile communications.

[Conventional technology]

Conventionally, mobile terminals used by others include mobile public terminals. When using this mobile public terminal, the user inserts a coin into the charge storage mechanism and then dials the number.

[Invention or problem to be solved]

However, as mentioned above, conventional mobile terminals cannot be used without coins, and the charge storage mechanism also has a size limit, making it inconvenient to carry if used continuously for a long period of time. Met.

The present invention has been made in view of the above points, and provides a leased mobile terminal in which the user pays the communication fee in advance and can use the mobile terminal freely up to that amount, in a system where the mobile terminal is used by another person. purpose.

[Failure to solve the problem]

FIG. 1 shows a basic configuration diagram of the present invention. In FIG. 1, a mobile terminal for leasing includes a storage means 1 for storing a preset communication fee, an accumulation means 2 for calculating and accumulating communication charges during mobile communication, and an accumulation amount or amount obtained by the accumulation means 2. Display means 3 for displaying the difference between the communicable amount stored in the storage means 1 and the accumulated amount, and disconnecting the mobile communication when the accumulated amount exceeds the communicable amount stored in the storage means 1. This is solved by having a communication disconnection means 4 that

[Effect]

When lending a device to a user, the user receives the communication amount in cash or a telephone card, and only lends the device with the communication amount entered to the user. Communication is cut off. In addition, the accumulated communication charges are displayed on the terminal to inform the user of the amount of communication that can be made later. Additionally, communication charges are calculated by the mobile terminal and independently from the exchange.

〔Example〕

FIG. 2 shows a block diagram of a terminal according to an embodiment of the present invention.

The allowable communication amount memory 101 in FIG. 2 corresponds to the storage means 1 in FIG. In FIG. 1, it corresponds to the display means 3, and the control section 103
, the telephone unit 104 corresponds to the communication disconnection means 4 in FIG.

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

The amount of money is input by connecting another computer (not shown) or a dedicated input device to the external terminal 102.

Since the input interface from the external terminal 102 of the control unit 103 is not made public, it is not possible to input the communication amount without permission. Furthermore, although this embodiment shows an example of input from the external terminal 102, there is also a method of manually inputting from the telephone unit 104 instead of the external terminal +02. In this case, it can also be done using the dial attached to the telephone unit 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), dialing a special identification number or pressing a special switch (step 33);

Indicate to the control unit 103 that this number is not a dialed number for communication (step 34), and input a predetermined password (step 35).

If the password preset in the control memory 105 and the password input in step 35 are the same, the process moves to step 37, and if they do not match, the process moves to step 35 (step 26).

A message prompting the user to input the available communication amount is displayed on the display unit 109 or notified by voice or tone on the telephone unit 104 (step 37). Next, the user inputs the communication fee from the dial section (step 38). As described above, even without using the external terminal 102, by keeping the password secret, unauthorized input of the communicable amount can be prevented. Only terminals in which the communication amount is entered are lent to the user. When using a terminal in which the available communication amount has been input, the user dials the other party's dial number from the telephone unit 104 in the same way as a normal mobile terminal.

The dialed digits are stored in the control unit 103 and sent from the transceiver 106 to a wireless base station (not shown).
It is connected to the general public telephone network via a mobile communication exchange and communicates using the same control as a normal car phone.

When communication begins, billing begins not only at the exchange but also at the mobile terminal at the same time.

The billing method at the mobile terminal requires call time and rate index. Due to the current signaling system between car telephones and wireless base stations, the wireless base station constantly sends out the wireless base station number, making it possible to know the wireless zone of the mobile terminal. The charge index calculation memory 10 stores a list for calculating the charge index from this wireless base station number and the area code of the called party's phone.
7, the rate index can be easily determined.

As a result, by using this signaling method, it is possible to receive information directly from the exchanger about whether there are public telephones used by an unspecified number of users or not.

A flowchart during communication is shown in FIG.

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

The dial number from the mobile station is obtained (step 41), and a charge index is calculated from the charge index calculation memory 107 (step 42). If communication is started, the process moves to step 44.
If communication has not started, the process moves to step 49 (step 43). The control unit 103 performs billing based on the charge index. The amount charged at this time does not have to be the same as the amount charged by the exchange, and may be one in which profit for leasing is added. In addition, current car phones use a distance-based time difference method that charges 10 yen every 6.5 seconds or 45 seconds depending on the communication distance, or it is possible to add a fixed amount of charges for each communication (step 44).

The charged amount is accumulated in the accumulated communication charge memory 108 each time it is charged, and the total amount is recorded in the available communication amount memo January 0
It is compared with the value of 1 (step 45). If the value of the available communication amount memo IJ 101 is larger than the value of the accumulated communication charge memory 108, communication continues, but if the value of the accumulated communication charge memo IJ I 08 becomes larger, the communication is cut off. At this time, the fee paid by the user in advance is
\It means that you have used it.

By constantly displaying the difference between the values in the communicable amount memory 101 and the accumulated communication fee memory 108 on the display unit 109 during communication (step 46), the user can know how much communication is left.

Further, if the value on the display section 109 becomes small, a notification is given by voice or tone, thereby preventing sudden disconnection during communication.

If the communication is disconnected, the process moves to step 30, and if it continues, the charging time is determined in step 48, and when the charging time has come, the charging amount is accumulated in step 44 (steps 47 and 48).
).

Furthermore, if the value in the available communication amount memory 101 is greater than the value in the cumulative communication fee memory 108 and the squirrel terminal is returned, the difference will be returned to the user.

In addition, in the above example, it is assumed that a preset amount is paid in advance, but if only the amount is set in advance, or if the loan is lent to a trusted user, the amount used can be paid later. It's okay.

〔Effect of the invention〕

As described above, according to the present invention, since coins are not used, it is possible to create a mobile terminal that is portable and can be used by an unspecified number of people. Also, since you can set the communication amount in exchange for the fee at the time of leasing, there is no possibility of unpaid fees. Since the difference between the accumulated amount and the available communication amount is displayed on the user side, the user can always check whether the communication is possible with the remaining amount, which improves the service quality.On the other hand, communication charges can be calculated on the mobile terminal independently of the exchange. This method has advantages such as being able to bill the lease fee in addition to the communication fee, and is effective when allowing someone else to use the mobile terminal.
