Abstract

PURPOSE:To reduce the traffic of a public telephone network, which is caused by charging, by providing a memory for storing the charging information registered in a charging means, in a mobile telephone set, in the charging means of the mobile telephone set. CONSTITUTION:The titled system is provided with a public communication network PSTN 1, a subscriber's line switchboard EO 2 in the PSTN 1, a subscriber's line 3, a fixed equipment 4 having a radio equipment for the mobile telephone system, a mobile telephone set 5, a fixed telephone 6, and a center 7 for executing the subscriber management of the mobile telephone system. In the telephone set 5, a charging memory is provided, and charging corresponding to a charging information amount which is stored in the charging memory is registered in the charging means through the metering means of the center 7 at every storing. As a call is executed, the charging information amount of this charging memory is decreased, and when it is used up, a call is inhibited. With this as a turning point, an application is made to the center 7, and the charging information is secured.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to billing means for a mobile telephone system using wireless transmission.

〔overview〕

The present invention provides a billing means for a mobile telephone, which includes a memory for storing billing information registered in the billing means, and when the amount of billing information reaches a predetermined value due to a call, a new billing means is added to the billing means. By storing the amount of billing information in memory via the system, it is possible to reduce the traffic on the public telephone network associated with billing.

[Conventional technology]

Car phones and cordless phones have been put into practical use as mobile phone systems that utilize wireless transmission.

All of these charges are performed on the exchange side.

In the case of a car phone, when a line is connected, the line is always relayed through a car phone exchange, where validation checks and billing are performed. Further, in the case of a cordless telephone, billing is performed at the subscriber line exchange that accommodates the subscriber line to which the base unit is connected.

[Problem that the invention seeks to solve]

However, in the case of a car phone, this conventional method has the drawback that the network is complicated and the system cost is high, and in the case of a cordless phone, connection can only be made through a fixed subscriber line. Therefore, it has the disadvantage that it cannot be moved and used over a wide range.

SUMMARY OF THE INVENTION The present invention aims to eliminate such drawbacks and to provide a mobile telephone system in which a mobile telephone and a fixed device are provided with billing functions.

[Means for solving problems]

The present invention comprises a center (7) connected to a public telephone network, a fixed device (4) connected to this public telephone network, and a mobile telephone (5) coupled to this fixed device by radio waves, The center is equipped with a registration means for registering a charge corresponding to the call volume of the mobile telephone, and the fixed device is configured to operate the mobile telephone in a mobile telephone system equipped with a management means for managing the call volume of the mobile telephone. The telephone includes a billing memory, a means for subtracting billing information in this billing memory in response to a call, a means for prohibiting a call when the billing information in this billing memory reaches a predetermined value, and a means for subtracting billing information in this billing memory. The present invention is characterized by comprising means for replenishing information and means for recording the amount of the replenished billing information.

[Effect]

Charges equivalent to the amount of billing information stored in the billing memory provided in the mobile telephone are registered in the billing means via the center's registration means each time the information is stored.

As calls are made, the amount of billing information in this billing memory decreases, and when it is used up, calls are prohibited. Taking this as an opportunity, they apply to the center anew and secure the amount of billing information.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram of a mobile telephone system to which the billing means of the present invention is applied. This system is a public communication network (
Hereinafter referred to as PSTN. ) 1, a subscriber line exchange (hereinafter referred to as EO) 2 in the PSTNl, and a subscriber line 3,
The system includes a fixed device 4 having a radio for a mobile telephone system, a mobile telephone 5, a fixed telephone 6, and a center 7 for managing subscribers of the mobile telephone system. In this system,
For the call connection, a line is set up via the mobile telephone 5, the fixed device 4, the PSTNI, and the fixed telephone 6.

FIG. 2 is a block diagram showing the configuration of the fixing device 4 of FIG. 1. This device includes an antenna 12, a control Ja 14 that performs connection control and billing control with the radio device 13, and a billing table 15 for calculating a billing index from a dial number.
a telephone line interface 16 with a subscriber line 3;
This device is connected to the subscriber line 3.

FIG. 3 is a block diagram showing the configuration of the mobile telephone 5 of FIG. 1. As shown in FIG. This device includes an antenna 21 and a radio 22.
, a controller 23 that performs connection control, billing control, etc., a billing memory 24 composed of non-volatile memory, a display operation section 25, a handset 26, and an ID1i1 reporting section 27 such as a subscriber number or machine number. Equipped with.

The present invention is characterized in that call charges are treated like gasoline in a car. That is, the billing memory 24 of the mobile phone 5 corresponds to the gasoline tank of a car, and in the same way as refueling at a gas station, the billing memory 24 is rewritten according to the procedure shown in FIG. 4 in the present invention. Gasoline is consumed when a car runs, but in this system, each time a communication is performed, the charging memory 2 is stored in the procedure shown in Figure 5.
The contents of 4 are counted down. For example, the billing memory 24 is rewritten to write the frequency of 10,000 yen. Each time you use it, the required amount is deducted from it.

If the balance reaches 0 yen, calls will be prohibited. However, the billing memory rewriting request is connected to the center 7 even if the balance is 0 yen.

〔Effect of the invention〕

As explained above, the present invention provides a billing function on the terminal side of the system (fixed device, mobile phone), thereby simplifying the network and reducing the system cost compared to the conventional car phone. It also has the effect of expanding the locations where cordless phones can be used.
