Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal device for communication carried by a user.

[0002]

2. Description of the Related Art In recent years, portable telephones (portable telephones) and PHs have been developed.
Portable terminal devices such as S (simple portable telephone) have been widely used. Such a mobile terminal device generally has a configuration in which a control unit, a transmission / reception unit, a display unit, a sound input / output unit, an operation unit, and the like are arranged in a housing.

[0003] In the case of communication between portable terminal devices having such a configuration, first, a sender transmits a message to the portable terminal device (hereinafter referred to as a first terminal).
The call number of the receiver's portable terminal device (hereinafter, referred to as a second portable terminal device) is pressed by, for example, a number key on the operation unit of the portable terminal device, and the communication start key is pressed.

Then, the call number is displayed on the display unit, and a communication signal is transmitted from the control unit to the nearest base station and mobile communication exchange (hereinafter simply referred to as base station) via the transmission / reception unit. Then, the communication signal received by the nearest base station is transmitted to the transmission / reception unit of the second mobile terminal device. The communication signal received by the transmitting / receiving unit of the second mobile terminal device is sent to the control unit, and a ringing tone is emitted from, for example, a speaker of the sound input / output unit.

[0005] When the receiver hears the ringing sound from the microphone, the receiver presses the communication start key of the operation unit of the second portable terminal device and responds to, for example, the microphone of the sound input / output unit. Then, a communication signal based on this response is transmitted from the control unit to the nearest base station via the transmission / reception unit. Then, the communication signal received by the nearest base station is transmitted to the transmitting / receiving unit of the first mobile terminal device. The communication signal received by the transmission / reception unit of the first portable terminal device is transmitted to the control unit, and a sound is emitted from, for example, a speaker of the sound input / output unit. Thereafter, communication becomes possible between the first and second portable terminal devices.

By the way, various service functions such as an answering machine service, a call waiting service, a transfer phone service, and the like can be set in the portable terminal device. The answering machine service is located in a place where the second mobile terminal device does not reach radio waves, such as in an underground mall or subway when the mobile terminal device is a mobile phone, and in a high-speed moving vehicle when the mobile terminal device is a PHS. At this time, the answering machine function of the base station receives the transmission signal from the first mobile terminal device in place of the second mobile terminal device, and receives a predetermined message (for example, "This is the *** number. I cannot answer the phone. Please record your name, phone number and message after the dial tone. ") To the first mobile terminal device.

However, even when such an answering machine service is set in the second portable terminal device, conventionally, for example, communication has been performed from the sender while the receiver is out of the communication range from the communication range. In such a case, the receiver may not realize that the answering machine service has been used by the sender even if the receiver returns to the service area thereafter.
It was necessary to inquire the presence / absence of a message from the portable terminal device to the answering machine function of the base station by manual access.

Therefore, a receiver for outputting out-of-communication range information from a received signal to a portable terminal device, a timer for arbitrarily setting the out-of-communication period, and a period longer than the period set by the timer based on the out-of-communication information of the receiver. Means for detecting that the user is out of the service area and then returns to the service area; means for generating a warning based on the detection result; and means for driving the transmitter to access the answering function of the base station. There has been proposed a portable terminal device which is capable of automatically accessing a warning generation and answering machine function when a receiver once goes out of the communication range and out of the communication range, and then returns to the communication range. See JP-A-9-46760).

According to such a portable terminal device, even if a message is recorded while the receiver is moving in and out of the communication area without communication, the message recording function can be performed. Automatically accesses the message, it is possible to prevent a problem that the message is not noticed for the first time after being left for a long time without notice.

[0010]

However, according to the conventional portable terminal device, the receiver recognizes from the outside of the communication area that he / she has returned to the communication area by a warning, and thereafter, for example, places his / her ear on a speaker to automatically access the area. It is necessary to confirm whether or not there is a message that has been recorded in the recorded message recording function. Therefore, the receiver may not be able to leave the portable terminal device even after returning to the communication range, and in that case, it is not possible to confirm whether or not there is a message recorded by the message recording function. There is.

[0011] Accordingly, an object of the present invention is to provide a portable telephone capable of recognizing whether or not there is a message recorded by the message recording function when the receiver returns from outside the communication area to the communication area. It is to provide a terminal device.

[0012]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a portable terminal device having a function of carrying and communicating via a base station, wherein the portable terminal device detects an out-of-communication range / communication range, and And a processing unit for automatically communicating with the communication terminal and displaying a result of the communication after the communication is displayed.

According to the above configuration, for example, when the receiver returns from the outside of the communication area to the communication area, the automatic answering function automatically displays and notifies whether or not there is an answering message. Therefore, regardless of the current status of the receiver, the receiver can be surely recognized whether or not there is a message recorded.

1).

First, the answering machine function of the base station receives a transmission signal from the first portable terminal device 100 instead of the second portable terminal device 100, and receives a predetermined message (for example, "This is the *** number. Please record your name, phone number and message after the dial tone. ") To the first mobile terminal device 100. Next, the sender records the necessary message from the first mobile terminal device 100 to the answering function of the base station according to the message.

Thereafter, the area detection circuit 201 of the second portable terminal device 100 keeps searching for the control channel of the nearest base station, and performs position registration with the base station, thereby possessing the second portable terminal device 100. That the receiving receiver has returned to the communication area from outside the communication area, and sends the detection result to the answer phone access circuit 202 (step S).
2).

The answer phone access circuit 202 starts automatic access to the answer phone function of the base station based on the detection result from the area detection circuit 201 (step S3).

That is, the answering machine access circuit 202 sends a transmission signal (hereinafter referred to as an access signal) for the answering service function of the base station to the time division multiplexing circuit 111B. The time-division multiplexing circuit 111B switches the access signal every fixed time (time slot) and sends out the signal to the modulator 112. Modulator 112 converts the access signal into an RF signal and sends it to mixer 113a. The mixer 113a, for example, receives a reference frequency signal TCOX of a quartz oscillator or the like, combines a signal from a frequency synthesizer 119 that operates and an access signal, and sends the resultant to the RF filter 114a.

The RF filter 114a filters the access signal to, for example, 1.429 GHz to 1.453 GHz and sends the filtered signal to the amplifier 115a. Amplifier 115a
Amplifies the access signal and sends it to the duplexer 122.
Then, the demultiplexer 122 demultiplexes the access signal into a transmission frequency and transmits the demultiplexed signal to the answer phone function of the base station via the transmission / reception antenna 121.

The answering machine function of the base station transmits a message indicating the presence of a message to the second portable terminal device 100 when there is an answering message. The splitter 122 of the second mobile terminal device 100 splits the received signal with a message (hereinafter, referred to as a message signal) received via the transmitting / receiving antenna 121 into a receiving frequency and sends it to the amplifier 115b (step S4). ). Amplifier 115b amplifies the message signal and sends it to RF filter 114b. The RF filter 114b converts the message signal into, for example, 1.477.
The signal is filtered to a frequency in the range of GHz to 1.501 GHz and transmitted to the mixer 113b. The mixer 113b combines the signal from the frequency synthesizer 119 with the message signal and sends the message signal to the first IF filter 117a.

3c to the second IF filter 117b. The second IF filter 117b converts the message signal into, for example, 1
The signal is filtered to 0.7 MHz and transmitted to the amplifier 115d. Amplifier 115d amplifies the message signal and sends it to demodulator 118. The demodulator 118 converts the message signal into a digital signal and converts the message signal into a time-division multiplexed circuit 111B.
Send to Then, the time division multiplexing circuit 111B sends the message signal to the message display control circuit 203 and the timer 204.

The message display control circuit 203 responds to the message signal from the time division multiplexing circuit 111B that the message recorded by the message recording function of the base station is present, for example, "the message recording is present". It is displayed on the display 131. At the same time, the timer 204
Starts the countdown of the set time by the message signal from the time division multiplexing circuit 111B (step S).
5, S6). Then, the countdown of the set time is stopped when the receiver manually accesses the answering machine function of the base station (steps S7 and S8).

On the other hand, if the receiver has not manually accessed the answering machine function of the base station when the set time is counted down to the end, a notification signal to that effect is sent to the notification circuit 205.
(Steps S7 and S9). Notification circuit 205
Is notified by the timer 204 that the vibrator 16
0 to vibrate the second mobile terminal device 100, or a predetermined warning sound from the speaker 141 of the sound input / output unit 140, for example, an intermittent electronic sound or voice, for example, "There is a message recorded." And the like, and notifies the receiver that the receiver has not manually accessed the answering machine function of the base station (step S10).

According to such a portable terminal device 100,
Even if a message is recorded while the recipient is in or out of communication range without knowing, the message recording function is automatically accessed. If you cannot return to the mobile terminal device even after returning to the area, you can reliably recognize whether or not there is a message that has been recorded by the answering machine function, so you can leave it for a long time without noticing the message. The trouble that can be noticed for the first time after manual access can be prevented.

In the above-described embodiment, the communication between the portable terminal devices has been described. However, the same effect can be obtained by the communication between the portable terminal device and a general telephone. Furthermore, a mobile phone has been described as an example of a mobile terminal device.
A portable terminal device using wireless communication such as HS can be similarly applied. Further, as an example where the mobile terminal device is placed in a place where radio waves do not reach, when the mobile terminal device is a mobile phone, it is placed in an underground shopping mall or a subway, and when the mobile terminal device is a PHS, it is placed in a high-speed moving vehicle or the like outside the communication range. However, the same effect can be obtained when the power of the portable terminal device is turned off, for example.

In addition, the notification of the presence of a message is performed when there is a message that has been recorded in the message recording function of the base station. However, the notification of the absence of a message may be performed when there is no message. . In addition, the present invention can be applied to services other than the answering machine service so as to achieve the same effect.

[0043]

As described above, according to the present invention, when the receiver returns from outside the communication area to the communication area, it is determined whether or not the receiver has a message recorded by the answering function. Since the message can be surely recognized, for example, it is possible to prevent a message from being deleted by leaving it unchecked for a long period of time.
