2. Description of the Related Art Conventional techniques relating to telephones for displaying call charges include, for example, JP-A-56-50655, JP-A-60-117958 and JP-A-62-1.
JP-A-88854 and JP-A-1-223869, for example, provide a service of renting a car telephone to a passenger in a taxi, and are used to settle the call fee.

In this type of conventional mobile phone system, for example, as disclosed in Japanese Utility Model Application Laid-Open No. Sho 62-188854, a user or the like performs a specific operation in order to know a call time and a call charge after using a telephone. , The talk time received from the exchange 1
It is a system that divides by the time per 0 yen and displays the call charge on the display unit. However, in conventional systems of this type, when used in Japan, the call charges are displayed in Japanese yen.For example, if the user is a foreign traveler, it must be converted to the local currency. If you don't know the price, you have to calculate it yourself or use another currency converter.

Some mobile phones have a calculation function. However, since the exchange rate fluctuates, it is necessary to remember the latest exchange rate one by one or to store the calculation function in the user's memory and update it appropriately. This is bothersome and troublesome.

[0005]

As described above, in the conventional mobile phone system for displaying the call charge on a mobile phone,
Only in the currency unit of your country (only in one currency unit)
Because call charges are not displayed, the system is difficult for foreigners to use.

The present invention has been made to solve such a problem, and even if a foreigner, the call charge is displayed in the currency of his / her own country, that is, the call charge is displayed in the unit of currency desired by the user. The purpose is to provide a mobile phone system.

[0007]

A portable telephone system according to the present invention is a portable telephone system for displaying a call charge on a portable telephone in a portable telephone system. And the charge sent from the exchange via the base station
Means for calculating Japanese yen call charges from rates and call duration
And means for using the exchange rate information to convert the Japanese yen call charge into a currency unit selected by a user and displaying the converted currency unit.

Further, in a portable telephone system constituted by portable telephones having a calculating function, each of the portable telephones can be used as a currency converter by utilizing the calculating function and the exchange rate information. And

The mobile telephone system of the present invention can be configured as described above to automatically display a call charge in a currency unit desired by the user on the mobile telephone. In this case, the mobile phone system for displaying the call charge on the mobile phone has a means for receiving the charge rate from the exchange in order to display the call charge even with the conventional system. It can be implemented only by adding a means capable of receiving the rate information and a simple arithmetic means.
