Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field of the Present Invention> The present invention relates to a public telephone.

<Prior art and problems to be solved> Public telephones and general subscriber telephones can only communicate at the installation location of the telephone.

For this reason, the use of mobile phones has been increasing in recent years.

However, the conventional mobile telephone uses a system similar to a subscriber telephone in which a telephone company (exchange office) bills a user for one month's call charge, so that a mobile terminal-specific incoming call is used. Considering the location registration process, there is a problem that the scale of the exchanges becomes enormous as the number of mobile phones increases in the future.

In order to solve this problem, the location registration process is not required because the mobile phone is dedicated to outgoing calls, and frequency storage means for storing a frequency corresponding to a prepaid fee is provided in the mobile phone, and the frequency is sequentially stored during a call. A system that eliminates the need for a call charge addition process on the switching center side by reducing the number is considered.

Considering such a system, it is extremely inconvenient to bring the mobile phone to a predetermined institution and pay the fee to re-store or recharge the mobile phone when reusing the mobile phone having lost the frequency. .

The present invention has been made to solve this problem,
It is an object of the present invention to provide a public telephone capable of performing a frequency replenishment process for a mobile telephone.

<Means for Solving the Problems> In order to solve the above problems, a public telephone according to the present invention comprises: a connecting means for a mobile phone; and at least a part of frequencies stored in an insertion card or a frequency corresponding to an inserted coin. Frequency replenishment means for replenishing the mobile phone via the connection means.

<Operation> Therefore, if a portable telephone is connected to the public telephone of the present invention and a card is inserted or a coin is inserted,
The desired frequency will be replenished to the mobile phone.

<Embodiment of the Present Invention> (FIGS. 1 to 3) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of a public telephone and a mobile phone according to one embodiment, and FIG. 2 is an external view of the public telephone and a mobile phone according to one embodiment.

This public telephone 10 is dedicated to a card. As shown in FIG. 2, a display 13 for displaying a frequency, a card insertion slot 14 and a dial key 15 are provided on an inclined operation surface 12 on the front side of a housing 11. Is provided.

An accommodation hole 18 for accommodating the mobile phone 1 and making a connection for replenishment is provided on the right side of the housing 11.

A connector 19 that can be connected to the mobile phone 1 is protruded from the lower end of the accommodation hole 18. A connector 8 provided at the bottom of the substantially rectangular parallelepiped mobile phone 1 is connected to the public phone side 10.
The width of the lower portion of the accommodation hole 18 is formed to be a width for guiding the mobile phone 1 so that the connector 19 can be easily mounted.

In this mobile phone 1, as shown in FIG. 1, a dial device 2 and a handset 3 are connected to a wireless transmitting / receiving unit 4,
It is connected to a base station (exchange station) by a radio signal input / output from the antenna 5.

The frequency storage unit 6 of the mobile phone 1 stores a predetermined frequency (for example, "500") at the start of use, and the frequency subtracting means 7 sequentially subtracts the frequency corresponding to the call charge, and the remaining frequency is small. (For example, “10”).

The frequency storage unit 6 is connected via a connector 8 so that reading and writing of the stored frequency can be performed.

As shown in FIG. 1, the public telephone 10 includes a card processing device 22 for processing a card based on signals from an off-hook detection unit 20 for detecting off-hook of the handset 16 and the completion of a call, and a charging signal detection unit 21. Have.

When the card processing device 22 receives the off-hook signal from the off-hook detecting means 20, the card can be accepted from the card insertion slot 14, the frequency information is read from the accepted card, and the frequency is displayed on the display 13. In addition, when the frequency is "1" or more, the generation of a dial signal from the dial signal generator 23 is enabled. Each time a billing signal is received, the frequency read is reduced by "1", and the remaining time is reached at the end of the call. The frequency is written on the card and returned.

Reference numeral 25 denotes a frequency replenishment unit for replenishing frequency to the mobile phone 1.

Reference numeral 26 denotes connection detecting means for detecting whether or not the connector 8 of the portable telephone 1 and the connector 19 of the public telephone 10 are correctly connected. An equivalent connection detection signal is output to enable acceptance of the card.

Reference numeral 27 denotes remaining frequency reading means for reading the remaining frequency stored in the frequency storage unit 6 of the mobile phone 1 after the connection is detected.

Reference numeral 28 denotes a replenishment for determining the replenishment frequency to the mobile phone 1 in response to the frequency read by the card processing device 22 after the connection is detected and the replenishment desired frequency input by operating the dial key 15. It is frequency determination means.

29 is an addition means for adding the replenishment frequency determined by the replenishment frequency determination means 28 and the remaining frequency read by the remaining frequency reading means 27, and 30 is the frequency of the mobile phone 1 which is the frequency added by the addition means 29. This is writing means for updating and storing in the storage unit 6.

31 is after the frequency replenishment is made to the mobile phone 1,
This is billing means for sending a billing signal for the replenished frequency to the card processing device 22.

Next, the operation of the public telephone 10 will be described with reference to the flowchart of FIG.

When the handset 16 is off-hook and the mobile phone 1 is housed in the housing hole 18 and connected by a connector, the mobile phone 1
Is read (steps 1 to 3).

Here, when the user inserts the card, the frequency B of the card is read, and it is determined whether or not the frequency B is positive (steps 4 and 5).

When the frequency B of the card is positive and the desired replenishment frequency C input by the user's dial operation is stored, the magnitudes of the frequency B and the frequency C are determined, and the frequency at which the frequency C can be replenished (B or less). If it is (frequency), the frequency C is determined as the replenishment frequency (P), and if it is a frequency that cannot be replenished (frequency greater than B), the frequency B becomes the replenishment frequency (P) (steps 6 to 9). .

The determined replenishment frequency P is the remaining frequency A of the mobile phone 1.
And the frequency (P + A) is written into the frequency storage unit 6 (steps 10 and 11).

When the frequency is written in the mobile phone 1, P billing signals are output to the card processing unit 22 (step 1).
2).

Due to the generation of the billing signal, the display on the display 13 changes from "B" to "BP" of the card frequency, and the user can confirm that the frequency replenishment for the mobile phone 1 is completed.

After the confirmation, when the user releases the connector connection between the mobile phone 1 and the public telephone 10, the connection detection is reset, and the card in which the frequency BP is written is returned (steps 13 and 14).

As described above, at least a part of the frequency of the card is replenished to the mobile phone 1, and the mobile phone 1 having no frequency can be reused.

If the handset 16 is off-hook, a well-known call accounting process is performed (step 15).

<Other Embodiments of the Present Invention> In the above-described embodiment, only the frequency was replenished to the mobile phone 1. However, the battery power of the mobile phone 1 is stored in the frequency storage 6 in advance. If the battery is charged only to guarantee the number of calls, as shown in FIG. 4, a charging circuit 40 for charging a battery (not shown) of the mobile phone via the connector 19, It is sufficient to provide a charging timer 41 for operating the charging circuit 40 only for a corresponding time (42 is a lamp indicating that charging is in progress). When performing this charging, the mobile phone is fixed to the public telephone.
