Abstract

PURPOSE:To confirm by whom a telephone set is called even if the set is called from plural callers by providing a nonvolatile memory storing plural caller telephone numbers on the radio calling device and displaying the stored numbers selectively. CONSTITUTION:When a caller applies radio calling, an exchange station drives a radio calling station and sends a signal representing a telephone number of the caller to the radio calling device 1 via the radio calling station. The radio calling device 1 receiving the call receives a call signal by a radio equipment 12 and after the signal is demodulated by a demodulator 13, a telephone number part of a message part is extracted by a telephone number extraction means 25b. The telephone number is stored in a nonvolatile memory provided to an IC card 5. The operation above is implemented for each incoming call. Then plural caller numbers stored on the said IC card 5 are displayed selectively on a display device 14. Moreover, the IC card 5 is loaded to a card reader of an object telephone set to apply automatic dialing to the caller.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio paging device that notifies a user of an incoming telephone call.

[Prior Art] Conventionally, a radio paging device has been used to inform a person who is away from home that he or she has something to do. This device would call the device and ring a buzzer if there was a need to contact the person in possession of the device. When the buzzer rang, the owner of this device would call a predetermined phone number from a nearby phone, such as a public phone, and ask about the necessary business.

However, the most common use among these uses is ``Who is calling and what number do you want me to call?''. In this case, it is necessary to remember the telephone number to be contacted, and if you forget this telephone number, you will not be able to contact the person.

For this purpose, in recent years, some phones have been equipped with simple displays, and some have included a message code in the call signal to display a specific message or contact number.

In this case, you can also call directly while looking at the displayed phone number.

[Problem to be solved by the invention] However, with such conventional devices, if there is a new call before the call is made, the display changes to that call.
There was a problem that the original display could no longer be recognized.

[Means for Solving the Problems] In order to solve such problems, the present invention provides a removably attached IC card with a non-volatile memory for storing a plurality of caller telephone numbers, It is designed to be displayed.

[Operation] Even if there are calls from multiple callers, they are stored, so by selecting one, you can find out who called. Further, when the IC card is attached to a telephone equipped with a reader/writer, the data stored in the IC card is used as data for automatic dialing.

[Example] FIG. 1 is a block diagram showing one embodiment of the present invention.

(Unnecessary if there is no need to guarantee the operation of the card alone).

The non-volatile memory 52 has an automatic call data storage area 52a therein, and when there is a call from a wireless calling station, the caller's telephone number is extracted from the call signal and automatically sent. It is stored and displayed in the transmission data storage area 52a. Moreover, this storage is not overwritten, but when calls are made one after another, they are stored in order, and the stored data can be read out later. Further, when the IC card is inserted into a telephone equipped with a reader/writer, the data stored in the automatic call data storage area 52a is read out, and an automatic call is made. However, if multiple caller phone numbers are stored, only the selected one will be displayed and automatically dialed.

The power adapter 6 connects commercial power (AC) to direct current power (DC).
It has an AC/DC converter 61 for converting into.

7 and is being charged. The coupling interface 20 with the IC card 5 may be a contact type using contacts or a non-contact type using electromagnetic induction.

In the figure, the IC card 5 is inserted into the wireless paging device 1 by inserting the IC card 5, but the IC card 5 may be inserted into the IC card 5 like a normal IC card reader/writer.

The operation sequence of this device is shown in FIG. 3.The operation sequence and the operation will be explained below.

First, determine the type of calling service for the person carrying this device. For example, there is a paging service in which an exchange automatically adds the caller's phone number to the ring signal, or when a call is received, a specific phone number is assigned to a specific code, and when the call is made, a specific code is attached. When the user makes a call, the wireless calling device 1 selects one option, such as a service that converts a specific code into a specific telephone number. Here, we will explain an example of a service in which the exchange automatically adds and calls the caller's telephone number as a message in the calling signal.

First step: The IC card 5 is installed in the radio paging device 1 (this device functions as a normal paging device when the IC card 5 is not installed).

When a caller (whose telephone number is 59-2324) makes a wireless call (la), the exchange A in which the caller's telephone is accommodated drives a radio paging station and transmits the caller's telephone number r592324. The radio calling station receives the signal and supplies it to the radio calling station.
The caller's phone number r5923 is included in the message section of the calling signal.
24" and makes a radio call (1c).

Step 2 The called radio paging device 1 receives the paging signal with the receiver 12, and converts the paging signal into a code with the demodulator 13. The telephone number part of the message part of the calling signal converted into a code is extracted by the telephone number extraction means 25b (
2a). This method takes advantage of the fact that the telephone number part consists only of numbers, and extracts only the numeric code of the message part and temporarily stores it in the RAM 23.

Then, the CPU 24 controls the IC card power control unit 22 to supply power to the IC card 5 via the coupling interface 20, and also communicates with the IC card 5 according to a communication procedure determined to store the data in the RAM 23. The stored caller telephone number "592324" is stored in the automatic call data recording area 52a of the nonvolatile memory 52 using the writing means 25c for recording data for automatic call in the IC card 5 (2b) .Furthermore, the CPU 24 controls the sound generator 17 to generate interrogation sounds from the speaker 16,
Notify the owner of this device of a radio call (2
c). At the same time, the display controller 15 is controlled to display the caller's telephone number 1592324J on the display 14 (2d).

Step 3 The owner of this device hears the sound output from the speaker 16 and knows that he has been called, and operates the sound stop key on the keypad 18 to stop the sound. Then, go to the nearest public telephone equipped with an IC card reader/writer or a telephone equipped with an IC card reader/writer (3a), take the telephone off-hook, and remove the IC card 5 (3a).
b) = When inserted into the IC card reader/writer (3c
) = IC card 5 is driven by the telephone (3d),
The drive is confirmed (3e).

After that, the automatic transmission data recording area 5 of the IC card 5
The data read request of 2a is executed (3f), and the caller telephone number "592324" recorded therein is read out and supplied to the telephone (3g).

Step 4 The telephone supplied with the caller's telephone number
592324" (4a),
Exchange B connects to exchange A (4b). As a result, exchange A notifies the caller of the incoming call (4C)
.

Step 5 When the caller answers after learning of the incoming call (5a)
, exchange A notifies exchange B of the response (5b
), exchange B notifies the telephone from which the called person made the automatic call of the response (5C).

Step 6 When the above sequence is completed, the communication path between the caller and the called party is completed, and both parties can talk (
6a).

The above explanation is based on an example in which the number of radio calls is one, but if calls are made multiple times from different telephone numbers, when recording the telephone number in the automatic call data recording area 52a in the process of symbol 2b, it is necessary to overwrite the telephone number. Instead, record multiple records by appending. Then, by processing symbol 3g, I
When you read the phone number from the C card 5, you can tell if there are multiple records, so in this case, display each phone number on the display of the phone and let the owner of this device select it (for example, by pressing the dial key). (1 to 9 are displayed and selected using the dial keys), and an automatic call is made to the selected telephone number.

When using the secondary battery 56 in the IC card 5, the IC
When the card 5 is being driven, it is charged from the secondary battery 26 of the radio paging device 1. Secondary battery 26 of radio paging device 1
when you do not need to use this device (when you return from a trip,
(when you are near your phone, etc.), power adapter 6
It is now possible to charge from commercial power using the

In the above embodiments, the telephone number of the caller included in the radio calling signal is based on the local area code, but it is of course possible to use the local area code. In addition, the caller phones with symbols 2a and 2b perform number extraction and writing processing, and symbols 2c and 2d.
The processes for ringing the speaker and displaying the caller's telephone number may be interchanged. Further, when the called party who knows that he/she has been called operates the keypad 18 to stop the sound from the speaker 16, the called party operates the operation keys and the number keys of the IC card 5 provided on the keypad 18, and the IC card 5 The telephone number recorded in 52a from the automatic call data recording area of If the number is too large or too small, you can delete it or change it to a predetermined phone number and overwrite the original area. Also I
If the non-volatile memory of the C card 5 already has an area for storing telephone numbers, such as a personal telephone directory, by operating the IC card operation keys and numeric keys provided on the keypad 18, the IC card 5 automatically records outgoing call data. Area 52a
The telephone number recorded in the telephone number can be displayed on the display 14 and easily stored in another file area of the non-volatile memory 52 such as a personal telephone directory.

[Effects of the Invention] As explained above, this invention stores multiple caller phone numbers in a removably attached IC card and selects and displays them, so it is not necessary to call first as in the past. This has the effect that the telephone number of the caller who made the call does not disappear and all the callers who made the call can be identified.
