When a dial button 8 is closed, a telephone number and its name stored in the RAM 5 are transferred to a portable telephone set as infrared ray data from a stimulation section 13 via a data transmission section 12. Upon the receipt of the data, the portable telephone set starts dialing to the telephone number automatically.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paging device represented by a so-called pager.

[0002]

2. Description of the Related Art Recently, mobile phones represented by mobile phones and car phones are becoming popular. For example, if you have a mobile phone and go on a trip, you can handle sudden calls.

However, in the case of a mobile phone, it is necessary to enable not only reception but also transmission, so it is necessary to maintain many base stations.

On the other hand, since the paging device only needs to receive, the burden on the maintenance of the base station is light.
As a result, in many cases the coverage of paging devices tends to be wider than that of mobile phones.

Therefore, if the user has both the paging device and the mobile phone, the user can receive a call with the paging device even in an area where the mobile phone cannot be used. At this time, the user can move to a region where the mobile phone can be used and make a call to a predetermined partner.

Therefore, it has been conventionally proposed to incorporate a paging device into a mobile phone. By incorporating a paging device into a mobile phone in this way, you can always receive a call service. When you receive a call, you can move to the area where you can call and immediately call the other party. Becomes

[0007]

In the conventional device, since the paging device is incorporated in the mobile phone as described above, the size of the device becomes large, and the mobile phone can be used as the large-sized mobile phone. Even in areas where it is not possible to carry it, the user always has to carry it, which is rather inconvenient.

In the case where the paging device and the mobile phone are separated from each other, it is convenient to carry only the paging device in an area where the mobile phone cannot be used, which is convenient. However, there is a problem in that the operability is poor because the mobile phone must make a call to the other party called by the paging device while looking at the telephone number displayed on the paging device.

The present invention has been made in view of such a situation, and makes it possible to satisfy both portability and operability.

[0010]

SUMMARY OF THE INVENTION A paging device of the present invention includes a receiving unit 2 as a detecting unit for detecting a call signal and a telephone number transmitted by radio, and a warning when the call signal is detected by the receiving unit 2. It is characterized by comprising a speaker 15 as a generating means for generating a sound, and a light emitting section 13 as a transmitting means for transmitting the telephone number detected by the receiving section 2 to other external equipment such as a mobile telephone by infrared rays. .

The telephone number detected by the receiving section 2 can be stored in the RAM 5 as a storage means.

[0012]

In the paging device having the above structure, the telephone number detected by the receiving section 2 can be transmitted from the light emitting section 13 to the mobile telephone by infrared rays. Therefore, it is possible to improve the operability without compromising the portability by separately configuring the paging device and the mobile phone.

1 is a block diagram showing the construction of an embodiment of a paging apparatus of the present invention. The receiving unit 2 detects an electric wave wirelessly transmitted from a base station (not shown) via the antenna 1 and demodulates the electric wave. CPU3
Controls the operation of each unit according to the program stored in the ROM 4. The RAM 5 stores various data as needed. Also LCD
6, the telephone number, name, and other information can be displayed as needed.

The input section 7 has at least a call button 8, a storage button 9, a sort button 10 and a display button 11, and is operated when instructing various processes. The drive circuit 14 drives the speaker 15 to generate a predetermined warning sound.
In addition, the data transmission unit 12 is configured to control the light emitting unit 13 to generate infrared rays and to transmit data such as a telephone number and a name to a mobile phone described later.

FIG. 2 shows an example of the configuration of a mobile phone used together with the paging device shown in FIG. The wireless unit 22 is connected to a microphone 23 and a speaker 24, wirelessly transmits an audio signal input from the microphone 23 to a base station (not shown) via the antenna 21, and receives the audio signal via the antenna 21. Demodulates the radio wave,
Audio is output from the speaker 24.
The CPU 25 is configured to control each part according to a program stored in the ROM 26. RAM2
Various data are stored in 7 as required. Further, the LCD 28 can display predetermined information such as a telephone number and a name. The input unit 29 is operated by the user when inputting a predetermined command. Also,
The light receiving unit 30 receives the infrared light emitted from the light emitting unit 13 shown in FIG. 1 and outputs a detection signal thereof to the receiving unit 31.

Next, referring to the flowchart of FIG.
The operation will be described. A program having the process shown in FIG. 3 is stored in the ROM 4 of the paging device, and the CPU 3 starts the process shown in FIG. 3 when the power of the paging device is turned on.

First, in step S1, it is determined whether a message has been received. That is, when the power is turned on, the receiving unit 2 is always in the standby state, and whether or not the calling signal is generated from the base station is checked.
It is constantly monitored via the antenna 1. When receiving the call signal through the antenna 1, the receiver 2 detects the call signal and outputs the detected signal to the CPU 3. At this time, C
The PU 3 transfers the message from the base station detected by the receiving unit 2 to the RAM 5 and stores the message (step S11).
This message includes, for example, the other party's telephone number and name. Next, in step S12, it is determined whether or not the time to call is designated. If this time is specified, step S13
Then, the time is stored in the RAM 5. If the time is not specified, this step S13
Processing is skipped.

Then, in step S14, a warning sound and a message are displayed. That is, the CPU 3 controls the speaker 15 via the drive circuit 14 to generate a predetermined warning sound. This allows the user to know that the calling signal has been detected. Further, the name of the other party, the telephone number, and the time to call, which are detected by the receiving unit 2 and stored in the RAM 5, are displayed on the LCD 6. The user can see this and know at that time that the other party should be called.

If it is determined in step S1 that no message has been received, step S2
Then, it is determined whether or not the time stored in the RAM 5 has arrived. The CPU 3 is always performing the time counting operation, and can determine whether or not the current time matches the time stored in the RAM 5.

When it is determined in step S2 that it is time to make a call, step S2
From step S14 to step S14, a warning sound is generated from the speaker 15 and the name and telephone number of the other party who should make a call at that time are output and displayed on the LCD 6 in the same manner as described above.

In step S2, the current time is RAM
If it is determined that the time for making a call is not stored in step 5, or if a warning sound is generated in step S14 and the name and telephone number of the other party are displayed on the LCD 6, then step S3 is performed. Then, it is determined whether or not the send button 8 has been operated. That is, the speaker 1
When the warning sound is generated by 5, if the area is an area where the mobile phone can be used, the user can immediately turn on the call button 8. In addition, when the user is in an area where the mobile phone cannot be used, the call button 8 can be turned on after moving to a position where the mobile phone can be used, if necessary.

When the call button 8 is turned on, the process proceeds to step 4 and the process of sending the call data to the mobile phone shown in FIG. 2 is executed. That is, when the call button 8 is operated, the CPU 3 reads out the telephone number and name of the other party stored in the RAM 5 and outputs them to the data transmitting unit 12. The data transmission unit 12 modulates this according to a predetermined format and controls the light emitting unit 13 to emit it as infrared data.

This infrared ray is received by the light receiving section 30 of the mobile phone shown in FIG. 2 and demodulated by the receiving section 31. The demodulation result is transferred to the RAM 27 and stored therein. When the telephone number is transferred by infrared rays from the paging device shown in FIG. 1 in this way, the CPU 25 automatically causes the wireless unit 22 to start a calling operation for the telephone number. As a result, the call to the other party is executed from the wireless unit 22 via the antenna 21. When the other party answers the call, the wireless unit 22
Transmits the voice signal of the user, which is input through the microphone 23, to the other party through the antenna 21, demodulates the voice signal of the other party received by the antenna 21, and outputs and emits the sound from the speaker 24. In this way, the user can communicate with the other party via the mobile phone.

After the processing of step S4 is completed, or when it is determined in step S3 that the call button 8 is not turned on, the process proceeds to step S5, and it is determined whether or not the memory button 9 is turned on. It When it is determined that the storage button 9 is turned on, the name and telephone number stored in the RAM 5 up to that point are extracted, read out, and transmitted to the mobile phone via the data transmission unit 12 and the light emitting unit 13. Let

In the mobile phone, this data is received via the light receiving section 30 and the receiving section 31, and is stored in the RAM 27. That is, when the memory button 9 is operated in this manner, the telephone number and name of the other party who has been called by the paging device are all the RAM 2 of the mobile telephone.
7 and stored.

When the processing of step S6 is completed, or when it is determined in step S5 that the memory button 9 is not turned on, the process proceeds to step S7, and it is determined whether or not the sort button 10 is turned on. If it is determined that the sort button 10 has been turned on, step S
In step 8, the stored data is sorted. That is, C
The PU 3 sorts the names and telephone numbers stored in the RAM 5 in alphabetical order based on the names.
If the name is not stored, the phone numbers are sorted in order. As a result, the data that has been stored in the calling order up to that point is rewritten into easy-to-read alphabetical data.

After the processing of step S8 is completed, or when it is determined in step S7 that the sort button 10 is not turned on, the process proceeds to step S9, and it is determined whether or not the display button 11 is turned on. It If it is determined that the display button 11 is turned on, the process proceeds to step S10, and the list display process is executed. That is, at this time, the CPU 3 reads out the data stored in the RAM 5 and outputs and displays it on the LCD 6. When the process of step S8 is being executed, the order of the names displayed on the LCD 6 at this time is not the order in which the call was received but the alphabetical order. As a result, the display is very legible.

When the process of step S10 is completed, or when it is determined in step S9 that the display button 11 is not turned on, the process returns to step S1 and the subsequent processes are repeatedly executed.

In the above embodiment, the infrared light output from the light emitting unit 13 of the paging device is received by the light receiving unit 30 of the mobile phone.
It is also possible to output infrared rays to a light receiving section provided in an electronic device (external device) such as a video tape recorder so as to operate them.

[0030]

As described above, according to the paging apparatus of the present invention, the telephone number detected by the detecting means is transmitted to the external device by infrared rays, so that the paging apparatus can be used in an area where the mobile telephone cannot be used. In an area where only a mobile phone can be used to receive a call and a mobile phone can be used, the telephone number detected by the paging device can be automatically transmitted to the mobile phone by infrared rays. As a result, it becomes possible to simplify the calling operation in the mobile telephone.
