Abstract

PROBLEM TO BE SOLVED: To surely deliver a message to an opposite party at a point of time when dialing is available in the case that dialing is disable and the message cannot be delivered to the opposite party. SOLUTION: When a PHS 'personal Handy phone system' terminal 1 is resident at the outside of a coverage zone of a base station and dialing to an opposite party is not replied, the telephone number of the opposite party is stored and a message of the caller is recorded. On the other hand, when the PHS terminal 1 enters the coverage of the base station and dialing is made available, it is informed to the user. In this case, the user confirms the recorded message by reproduction and the stored telephone number of the opposite party is automatically dialed to call the opposite party. When the opposite party replies the call, the confirmed message is delivered orally to the opposite party. Thus, even when dialing becomes impossible to the opposite party, the message may be surely delivered to the opposite party when the dialing is made available.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile radiotelephone device used in PHS (Personal Handyphone System).

[0002]

2. Description of the Related Art A mobile radio system called PHS, which has started service this year, has its service range expanded at any time with the addition of base stations, and the call charge and the price of the PHS terminal itself are low. Therefore, it is spreading rapidly. When a calling operation is performed in such a PHS terminal, this operation information is transmitted to the nearest base station as a radio signal together with the ID code of this PHS terminal. When the base station receives the operation information or the like sent from the PHS terminal, it transmits it to the exchange through the connected line. In this case, the exchange side receives this PH received together with the operation information.
If the ID code of the S terminal is registered, transmission of this PHS terminal is permitted, and as a result, the other party is called based on the received operation information (that is, the dial number of the other party).
Then, when the other party responds to the call, the call by the PHS terminal is started.

[0003]

Such a PHS terminal is not connected to the other side because the operation signal cannot be transmitted to the base station side even if the transmission operation is performed outside the area of the base station. Therefore, it is not possible to talk with the other party. Further, even if it is within the area of the base station, if the call is transmitted while moving at a speed equal to or higher than a predetermined speed, the operation signal is not accurately transmitted to the base station side, and thus it is not possible to similarly talk with the other party. As described above, in the PHS, even if the user makes a call at the time when he / she wants to convey a message to the other party, it may not be possible to connect to the other party. Therefore, the user
After a while, I forgot to call the other party,
As a result, there arises a problem that the message is not transmitted to the other party. Therefore, an object of the present invention is to make it possible to accurately transmit a message to the other party at the time when the call can actually be transmitted even when the call cannot be transmitted to the other party and the message cannot be transmitted to the other party.

[0004]

In order to solve such a problem, the present invention provides a recording means for recording a message to be transmitted to the other party when the transmission to the base station is disabled when the transmission is made to the base station. It is provided with a judging means for judging whether or not a message is recorded by the recording means when the station is in a callable state, and a notifying means for notifying the callable state according to the judgment output of the judging means. . Therefore, PHS
If the terminal is unable to make a call when making a call to the base station, it will record the message to be transmitted to the other party. If is recorded, the user is informed that the PHS terminal is ready to make a call. As a result, even when the call cannot be transmitted to the other party at the time of attempting to make a call to the other party, the fact that the PHS terminal is ready to make a call is notified to the user even if the message cannot be transmitted to the other party. The message can be reproduced and confirmed at a point in time, and thus the message can be accurately transmitted to the other party.

[0005] In addition, when the call cannot be made to the base station, a registration means for registering the telephone number of the other party,
Reproduction means for reproducing the message of the recording means in response to a predetermined operation when the notification means notifies the transmission enabled state, and transmission means for automatically transmitting the telephone number of the registration means after the reproduction means completes the reproduction of the message. And are provided. As a result, even when the telephone number of the other party is forgotten, it is possible to automatically call and call the other party. In addition, if the call cannot be made to the base station, the registration means for registering the other party's telephone number and automatic call mode, and if the automatic call mode is registered, the register means's telephone number is automatically The transmitting means for transmitting and the reproducing means for reproducing and outputting the message of the recording means when the response of the other party is detected after the transmitting and outputting of the transmitting means are provided. As a result, when the PHS terminal is ready to make a call, it is possible to automatically call the other party and send a message. Further, the judging means judges whether or not the sound recording means is recording when the designated transmission time is reached and the base station is ready to make a call, and the notifying means notifies the callable state according to the judgment output of the judging means. It was done like this.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 2 is a block diagram of a base station forming a mobile radio system called PHS. In the figure, the base station 3 includes a radio transceiver 31, a modem demodulator 3
2, channel codecs 33 and 35, voice codec 34, modem demodulator 36, CPU 37, and 2-wire to 4-wire converter 38. Then, the 2-line to 4-line converter 3
A telephone line is connected to the end of 8, and an exchange (not shown) is connected through this telephone line. In addition, the wireless transmission / reception unit 31 includes a reception amplifier 311, first to third mixers 312 to 312.
314, the intermediate frequency generation unit 315, the quadrature modulator 316, the transmission amplifier 317, the antenna switch 318 that switches between transmission and reception of the antenna AT, and the first to third mixers 312 to 3
It comprises a PLL synthesizer 119 for supplying a predetermined frequency signal to 14 and the like.

Next, FIG. 1 is a block diagram of a PHS terminal which is a mobile radiotelephone device wirelessly connected to the base station 3.
It has almost the same configuration as the base station 3. That is, PHS
The terminal 1 includes a wireless transceiver 11, a modem demodulator 12, channel codecs 13 and 15, a voice codec 14,
Modem demodulator 16, CPU 17, dial keys, setting keys for setting manual and automatic modes for this device,
The keyboard 18 includes a recording key and a reproducing key, and a recording / reproducing IC 21 that records and reproduces a voice signal. In addition, the wireless transmission / reception unit 11 includes a reception amplifier 11
1, the first to third mixers 112 to 114, the intermediate frequency generator 115, the quadrature modulator 116, the transmission amplifier 117, the antenna switch 118 for switching the transmission and reception of the antenna AT, the first to third mixers 112 to 114, and the like. Of the PLL synthesizer 119 for supplying the frequency signals of

In the PHS terminal 1 thus constructed, when a dial call operation is performed using the keyboard 18, the CPU 17 detects this and the dial operation information is stored in a fixed memory (not shown). The code is transmitted to the base station 3 side as a radio signal via the modem modulator 16 and the radio transmission / reception unit 11. Such calling operation information is transmitted to the base station 3 via the control channel of any time slot with the base station 3. In this case, the base station 3 transmits this calling operation information to the exchange through the connected telephone line. However, if it is determined that the ID code included in the calling operation information is registered on the exchange side, the PHS terminal 1 Is permitted, and as a result, the other party is called. Then, when the other party responds, the call by the PHS terminal 1 via the call channel of the above-mentioned time slot is started.

As described above, the PHS terminal 1 cannot always make a call because it cannot make a call if it is outside the area of the base station 3. Therefore, after the user tries to convey the message to the other party and makes a call, it becomes impossible to make a call and then P
Even if the HS terminal tries to make a call again when it can actually make a call, at that time, the user forgets the message to be transmitted to the other party, or even forgets to make the call. Therefore, in the present invention, when communication with the other party becomes impossible, the other party number is stored and the message to be transmitted to the other party is recorded. Then, the PHS terminal reproduces the partner number and the message to be transmitted to the partner when the PHS terminal becomes ready to make a call, and notifies the user that there is a message to contact.

FIG. 3 is a flowchart showing the operation of such a PHS terminal 1. The operation of the main part of the present invention will be described with reference to this flowchart. When the user makes a call using the PHS terminal 1, if the PHS terminal 1 is outside the area of the base station 3 (out of service area), or if the PHS terminal 1 is moving at a speed equal to or higher than a predetermined speed, Calling becomes impossible. In this case, the CPU 17 of the PHS terminal 1 stores the calling number (partner dialing number) at this time in the memory 22. When a predetermined operation by the user's keyboard 18 is detected, the CPU 17 drives the recording / playback IC 21 to record the user's message from the microphone 20 in the recording / playback IC 21 via the voice codec 14, and the message is recorded. The memory 22 stores the information. Furthermore, C
PU17 is a manual mode by the user's keyboard 18,
Alternatively, when the setting operation of the automatic mode is detected, either the manual mode or the automatic mode is stored in the memory 22.

[0011] The PHS terminal 1 having the above-mentioned various settings
Comes into the range of the base station 3, it determines "Y" in step S1. In this case, the CPU 17 determines in step S2 whether or not a message is recorded in the recording / playback IC 21 based on the storage condition of the memory 22, and if message recording is being performed, the process proceeds to step S3 to store in the memory 22. Whether or not the manual mode is set is determined based on the contents.

If the manual mode is set, the user is informed in step S4 that a message for the other party is being recorded by sending a message from the speaker or displaying it on a display (not shown). To do. When the user performs a reproducing operation using the keyboard 18 while noticing the notification of the message recording, the CPU 17 reproduces and drives the recording / reproducing IC 21 in step S5, and the user records outside the service area of the base station 3. The message is reproduced and emitted to the speaker 19 via the voice codec 14. As a result, the user can reconfirm the message to be transmitted to the other party.

When such a reproducing operation is completed, the CPU 1
In step S6, the CPU 7 determines whether or not the other party dial number is stored in the memory 22. If the other party's number is stored here, an automatic dialing process for transmitting this number and the ID code of this terminal 1 to the base station 3 via the control channel is performed in step S7. In this way, the dialing process is performed so that the other party is called as described above. Here, a signal indicating the response of the other party is transmitted from the base station 3 side as a wireless signal, and when the "other party's response" in step S8 is determined to be "Y", a call through the user's call channel is started. . In this case, the user is
The message reproduced from the reproduction IC 21 and reconfirmed is verbally transmitted to the other party. Then, when the user performs an end call operation using the keyboard 18 during a call, the CPU 17 determines “End Call” in step S9 to be “Y”, and outputs the end call information to the base station 3 side via the control channel. To end the call with the other party.

When the response of the other party is not detected for a certain period of time as a result of the automatic dial transmission, it is judged in step S10 whether or not there is a resend request based on the operation of the user. After performing the stop process of step S11, the process waits for a predetermined time in step S11. Then, in step S7, the automatic dialing process is executed again. Note that such automatic dial transmission is performed a predetermined number of times such as three times.

As described above, when the PHS terminal 1 is outside the service area of the base station 3 and makes a call to the other party and the call cannot be made, the other party's number is stored and a message to be transmitted to the other party of the user is recorded. On the other hand, this PHS terminal 1
When it becomes possible to make a call by entering the area, the user is notified of this fact. In this case, the user plays back the recorded message and confirms it.
When the stored party number is automatically sent and the party responds,
This confirmed message is transmitted to the other party. Therefore,
Even if the call cannot be made to the other party at the time of attempting to make a call to the other party, the message can be accurately transmitted to the other party at the time when the call can be actually made.

In the case of "N" in step S6, the partner number is not stored in the memory 22 and only the message to the partner is recorded in the recording / reproducing IC 21, and the PHS is set.
Alternatively, when the terminal 1 enters the service area and is notified that the message recording is registered and is reproduced, the user may operate the other party's number to dial.

On the other hand, when the PHS terminal 1 enters the area from the outside of the base station 3, the recording / playback IC 21 is informed that there is a message recording, and if the memory 22 is set to the automatic mode, step S3. Is "N", and automatic dialing based on the partner number stored in the memory 22 is executed in step S12. When a response from the other party is detected as a result of the dial transmission, the CPU 17 causes the recording / playback IC 21 in step S14.
Is driven to reproduce the message message recorded by the user outside the service area of the base station 3. In this case, the reproduced message is transmitted to the base station 3 side as a radio signal of the communication channel via the channel codec 15, the modem demodulator 16 and the radio transmitter / receiver 11, and is further transmitted via the base station 3 and the exchange. Transmitted to the side.

Here, as a result of the automatic dial transmission,
If the response of the other party is not detected for a certain period of time and the determination in step S13 is "N", the automatic dial transmission stop process is performed and then the process waits for a predetermined period of time in step S16. After that, the process returns to step S12 and the automatic dialing process is executed again to call the other party. Further, when there are a plurality of messages to be transmitted to the other party and the remaining message cannot be transmitted due to a failure of the other party's terminal during message transmission, and only about half of the messages to be transmitted can be transmitted (that is, in step S15). (When the judgment is "N")
Similarly performs a process of stopping the automatic dial transmission and then waits for a predetermined time in step S16. Then, step S
Returning to step 12, the automatic dialing process is executed again to call the other party, and the remaining messages are transmitted. Note that such automatic dial transmission is performed a predetermined number of times such as three times.

As described above, when the PHS terminal 1 is out of the service area of the base station 3 and makes a call to the other party and the call cannot be made, the other party's number is stored and a message to be transmitted to the other party of the user is recorded. On the other hand, this PHS terminal 1
When entering the area, the call is automatically transmitted based on the other party's number, and when the other party answers, the message is automatically reproduced and transmitted to the other party. Therefore,
Even if the call cannot be made to the other party at the time of attempting to make a call to the other party, the message can be accurately transmitted to the other party at the time when the call can be actually made. In addition,
When the call to the other party becomes impossible, the designated call time is set in the memory 22, and when the designated time comes and the PHS terminal 1 is within the range of the base station 3 and the call is possible, use It is also possible to notify the person to make a call to the other party.

[0020]

As described above, according to the present invention, P
If the HS terminal cannot make a call when making a call to the base station, a message to be transmitted to the other party is recorded,
When it becomes possible to make a call to the base station, it is determined whether or not the message is recorded by the recording means, and if the message is recorded, the PHS terminal is made to notify the user that the call is made possible. , Even if the call cannot be made to the other party at the time of attempting to make a call to the other party, the user is informed of this when the PHS terminal is ready to make a call even if the message cannot be transmitted to the other party. The message can be played back and confirmed, so that the message can be accurately transmitted to the other party.

In addition, when the call cannot be made at the time of making a call to the base station, the telephone number of the other party is registered, and when a predetermined operation is performed when the call ready state is notified, the message of the recording means is reproduced. , After the message has been played, the registered phone number is automatically called, so even if you forget the phone number of the other party, you can automatically call the other party to call. . In addition, if the call cannot be made when making a call to the base station, the other party's telephone number and automatic call mode are registered, and when the callable state is notified, the registered telephone number is automatically called, When the response is made, the message of the recording means is reproduced and sent to the other party, so that when the PHS terminal becomes ready to make a call, the other party can be automatically called to send the message.
