Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio paging apparatus for notifying a user of an incoming call.

[Prior art] Conventionally, in order to inform people on the go that there is a business,
A wireless paging device is used. This was to call the device and sound the buzzer whenever there was a desire to contact the person carrying the device. The owner of this device calls a predetermined telephone number when the buzzer sounds from a nearby telephone such as a public telephone, and listens to necessary matters.

However, the most common of these uses is
It is a matter of "what number should be called because there was a call from whom". In this case, it is necessary to remember the telephone number to be inquired, and if the telephone number is forgotten, it becomes impossible to contact. For this reason, in recent years, there has been provided a simple display device for displaying a specific message or a contact number by putting a message code in a calling signal. In this case, it is possible to make a direct call while looking at the displayed telephone number.

[Problems to be Solved by the Invention] However, such a conventional apparatus has a problem that if there is a new call before the contact is made, the display changes to that, and the original display cannot be understood.

[Means for Solving the Problems] In order to solve such a problem, the present invention provides a non-volatile memory for storing a plurality of caller telephone numbers in an IC card which is detachably attached, and selects the nonvolatile memory. This is displayed.

[Operation] Even if there are calls from a plurality of callers, those are stored, so that it is possible to know who has been called by selecting them. When the IC card is attached to a telephone with a reader / writer, the data stored in the IC card is used as data for automatic transmission.

As a method of mounting the IC card 5, the wireless calling device 1 side inserts the IC card 5, but the IC card 5 may be inserted like a normal IC card reader / writer.

FIG. 3 shows the operation sequence of this device. Hereinafter, the operation sequence will be described, and the operation will be described accordingly.

First, the type of call service for a person carrying this device is determined. For example, a call service where the exchange automatically adds the caller's telephone number to the call signal, or assigns a specific code to a specific code when receiving a call, and attaches a specific code when calling. When called, a service for converting a specific code into a specific telephone number is selected in the radio pager 1. Here, a description will be given of an example of a service in which an exchange automatically calls a call signal by adding a caller's telephone number to a call signal as a message.

First step Insert the IC card 5 into the wireless calling device 1 (this device
When the IC card 5 is not inserted, it functions as a normal calling device.) Caller (Phone number is 59-
2324) makes a radio call (1a), the exchange A in which the caller's telephone is accommodated drives the radio call station and sends a signal representing the caller's telephone number "592324" to the radio call station. (1b). For this reason, the radio paging station receives the call and performs a radio call including the caller's telephone number "592324" in the message portion of the call signal (1c).

Step 2 The called paging apparatus 1 receives the paging signal at the receiver 12, and converts the paging signal into a code at the demodulator 13. The telephone number portion of the message portion of the call signal converted into the code is extracted by the telephone number extracting means 25b (2
a). This method utilizes the fact that the telephone number portion is composed of only numbers, and extracts only the numeric code of the message portion and temporarily stores it in the RAM 23.

Then, the CPU 24 controls the IC card power control unit 22 to
The power is supplied to the card 5 through the coupling interface 20, and the card 5 is communicated with the IC card 5 according to a predetermined communication procedure, and the caller telephone number “592324” stored in the RAM 23 is automatically transmitted to the IC card 5. The data is stored in the automatic transmission data recording area 52a of the nonvolatile memory 52 by using the writing means 25c for recording the transmission data (2b). Further, the CPU 24 controls the sound generation unit 17 to generate an intermittent sound from the speaker 16, and notifies the owner of the device that the wireless call is made (2c). At the same time, the display controller 15 is controlled to display the caller telephone number "592324" on the display 14 (2d).

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

After that, the area 52 for recording automatic transmission data of the IC card 5
The data read request of a is executed (3f), and the caller telephone number “592324” recorded therein is read,
Supplied to the phone (3g).

Step 4 The telephone to which the caller telephone number has been supplied automatically makes an outgoing call to the telephone number "592324" (4a), so that the exchange B connects to the exchange A (4b). As a result, the exchange A notifies the caller of the incoming call (4c).

Step 5 When the caller who knows that there is an incoming call answers (5
a), exchange A notifies exchange B of the response (5).
b), exchange B informs the telephone automatically called by the called person of the answer (5C).

Step 6 When the above sequence is completed, the connection of the communication path between the calling party and the called party is completed, and the two parties can communicate with each other (6a).

The above description is an example in which the number of wireless calls is one. However, when the telephone number is called a plurality of times from different telephone numbers, the telephone number is overwritten when the telephone number is recorded in the automatic call data recording area 52a in the processing of the symbol 2b. Instead, it is recorded in multiple records by appending. Then, when the telephone numbers are read from the IC card 5 in the processing of the symbol 3g, it can be understood that there are a plurality of records. In this case, each telephone number is displayed on the display unit of the telephone and selected by the owner of the device. (For example, a display corresponding to dial keys 1 to 9 is made, and selection is made with the dial keys), and an automatic call is made to the selected telephone number.

When the secondary battery 56 in the IC card 5 is used, when the IC card 5 is driven, the secondary battery of the wireless calling device 1 is used.
Charge from 26. When the secondary battery 26 of the wireless calling device 1 does not need to use this device (for example, when returning from a place where the user is away from home or near his / her telephone), the secondary battery 26 is charged from a commercial power source using the power adapter 6. It has become.

In the above-described embodiment, the telephone number of the caller included in the radio call signal is based on the local station number. Also, the process of extracting and writing the numbers of the caller telephones of the symbols 2a and 2b and the process of sounding the speaker and displaying the caller telephone numbers of the symbols 2c and 2d may be switched. Further, when the called party who knows that the call has been made operates the keypad 18 to stop the sound of the speaker 16, the operation keys of the IC card 5 provided on the keypad 18 and the numeric keys are operated, and The telephone number recorded in the automatic transmission data recording area 52a of the card 5 is displayed on the display 14 to check the automatic transmission destination and judge whether the telephone number is valid or not. If the number is too large or too small, the original area can be overwritten by processing such as deleting it or changing it to a predetermined telephone number. If an area for storing a telephone number such as a personal telephone directory already exists in the non-volatile memory of the IC card 5, the IC card operation keys and numeric keys provided on the keypad 18 are operated to automatically transmit the IC card 5. The telephone number recorded in the data recording area 52a is displayed on the display 14, and can be easily stored again in another file area of the nonvolatile memory 52 such as a personal telephone directory.

[Effects of the Invention] As described above, according to the present invention, a plurality of caller telephone numbers are stored in an IC card which is detachably attached and selected and displayed. This has the effect that the caller telephone number that made the call does not disappear and all callers who made the call can be identified.
