DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mobile radio telephone used in a PHS (Personal Handy Phone System).

[0002]

2. Description of the Related Art A mobile radio system called PHS, whose service has started this year, has its service range expanded at any time with the addition of base stations, and the telephone charges 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 the PHS terminal. When the base station receives the operation information and the like sent from the PHS terminal, it transmits it to the exchange via the connected line. In this case, the exchange receives this PH received with the operation information.
If the ID code of the S terminal is registered, the transmission of the PHS terminal is permitted, and as a result, the other party is called based on the received operation information (that is, the other party dial number).
Then, when the other party answers the call, a telephone 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 calling operation is performed outside the area of the base station. Therefore, you cannot talk to the other party. Also, if the signal is transmitted while moving at a speed equal to or higher than a predetermined speed even within the area of the base station, the operation signal is not accurately transmitted to the base station side, so that it is impossible to make a call with the other party. As described above, in the PHS, there is a case where the connection cannot be established with the other party even if the user makes a call at the time of transmitting the message to the other party. For this reason, the user
After a while, I forget to call the other party,
As a result, there is a problem that the business 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 when the call can be actually transmitted, even if the call cannot be transmitted to the other party and the message cannot be transmitted to the other party.

[0004]

SUMMARY OF THE INVENTION 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 a call cannot be made to the base station; A determination means for determining whether or not a message is recorded by the recording means when the station is ready for transmission, and a notification means for notifying the transmission enabled state according to a determination output of the determination means. . Therefore, PHS
If the terminal cannot make a call to the base station when making a call to the base station, it records the message to be transmitted to the other party. Is recorded, the user is notified that the PHS terminal is in a state where transmission is possible. As a result, even if the call cannot be made at the time of trying to make a call to the other party and the message cannot be transmitted to the other party, the user is notified when the PHS terminal is ready to make a call. At this point, the message can be reproduced and confirmed, so that the message can be accurately transmitted to the other party.

[0005] Further, a registering means for registering the telephone number of the other party when a call cannot be made when making a call to the base station;
Reproducing means for reproducing the message recording means in response to a predetermined operation when the transmittable state is informed by the informing means, after the end of the reproduction of the message by the reproducing means, and transmitting means for outgoing telephone number registration means It is provided.
As a result, even if the telephone number of the other party is forgotten, it is possible to automatically call the other party and make a call. In addition, when a call cannot be made when making a call to the base station, the registration means for registering the other party's telephone number and the automatic call mode, and automatically registering the telephone number of the registration means when the automatic call mode is registered. The transmitting means is provided with a transmitting means for transmitting, and a reproducing means for reproducing and outputting a message of the recording means when a response from the other party is detected after the transmitting means outputs. As a result, when the PHS terminal becomes ready to make a call, it is possible to automatically call the other party and send a message.
The determining means determines the presence or absence of recording by the recording means when the designated transmission time comes and the transmission is possible to the base station, and the notifying means notifies the possible transmission state according to the determination output of the determining means. It is like that.

FIG. 2 is a block diagram of a base station constituting a mobile radio system called PHS. In the figure, a base station 3 includes a radio transmitting / receiving unit 31, a modem demodulator 3
2. It comprises a channel codec 33, 35, a voice codec 34, a modem demodulator 36, a CPU 37, and a two-wire / four-wire converter 38. And a two-wire / four-wire conversion unit 3
A telephone line is connected to the end of 8, and an exchange (not shown) is connected via the telephone line. The wireless transmitting / receiving unit 31 includes a receiving amplifier 311, first to third mixers 312-
314, an intermediate frequency generator 315, a quadrature modulator 316, a transmission amplifier 317, an antenna switch 318 for switching between transmission and reception of the antenna AT, and first to third mixers 312 to 3-3
It comprises a PLL synthesizer 119 for supplying a predetermined frequency signal to 14 or the like.

Next, FIG. 1 is a block diagram of a PHS terminal which is a mobile radio telephone device wirelessly connected to the base station 3,
The configuration is almost the same as that of the base station 3. That is, PHS
The terminal 1 includes a wireless transmission / reception unit 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 the apparatus,
The keyboard 18 includes a recording key and a reproduction key, and a recording / reproduction IC 21 for recording and reproducing an audio signal. The wireless transmitting / receiving unit 11 includes a receiving amplifier 11
1, predetermined for 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 between transmission and reception of the antenna AT, and the first to third mixers 112 to 114 And a PLL synthesizer 119 for supplying a frequency signal of

In the PHS terminal 1 configured as described above, when a dial transmission operation is performed using the keyboard 18, the CPU 17 detects this and transmits this dial operation information to an ID stored in a fixed memory (not shown). Along with the code, the signal is transmitted as a radio signal to the base station 3 via the modem modulator 16 and the radio transmission / reception unit 11. Such transmission operation information is transmitted to the base station 3 via a control channel in any time slot with the base station 3. In this case, the base station 3 transmits the transmission operation information to the exchange via the connected telephone line. When the exchange determines that the ID code included in the transmission operation information is registered, the PHS terminal 1 Is permitted, and as a result, the other party's call is made. When the other party answers, a call by the PHS terminal 1 via the above-mentioned time slot communication channel is started.

As described above, the PHS terminal 1 cannot always make a call, for example, cannot make a call outside the area of the base station 3, and cannot always make a call. For this reason, after the user tries to transmit a message to the other party and makes a call,
Even if the HS terminal attempts to make a call again when it can actually make a call, there arises a problem that at that time the user forgets the business to be transmitted to the other party or even forgets the call. For this reason, in the present invention, when communication with the other party is disabled, the other party number is stored, and a message to be transmitted to the other party is recorded. Then, when the PHS terminal is ready to make a call, the stored party number and the message to be transmitted to the partner are reproduced, and the user is notified that there is a message to be contacted.

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 out of the area of the base station 3 (out of service area), or if the PHS terminal 1 is moving at a speed higher than a predetermined speed, Outgoing calls become impossible. In this case, the CPU 17 of the PHS terminal 1 stores the calling number (the other party dial number) at this time in the memory 22. When a predetermined operation of the user's keyboard 18 is detected, the CPU 17 drives the recording / reproducing IC 21 to record the user's message from the microphone 20 to the recording / reproducing IC 21 via the voice codec 14 and record the message. The memory 22 stores the information. Further, C
PU 17 is a manual mode using the user's keyboard 18,
Alternatively, when the setting operation of the automatic mode is detected, one of the manual mode and the automatic mode is stored in the memory 22.

[0011] The PHS terminal 1 in which such various settings are made
Is within the range of the base station 3, the “range?” Of step S1 is determined to be “Y”. In this case, the CPU 17 determines in step S2 whether or not a message has been recorded in the recording / reproducing IC 21 from the storage state of the memory 22. If the message has been recorded, the process proceeds to step S3 to store the message in the memory 22. It is determined whether the manual mode is set based on the content.

If the manual mode is set, the user is notified in step S4 that a message to the other party has been recorded by sending a message from a speaker or displaying on a display (not shown). I do. When the user notices the notification of the message recording and performs the reproducing operation using the keyboard 18, the CPU 17 drives the recording / reproducing IC 21 to reproduce in step S5, and the user performs the recording outside the area of the base station 3 or the like. 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 the reproducing operation is completed, the CPU 1
7 determines whether or not the other party's dial number is stored in the memory 22 in step S6. Here, if the other party number is stored, an automatic dialing process for transmitting the number and the ID code of the terminal 1 to the base station 3 via the control channel is performed in step S7. In this manner, 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 radio signal, and when the "other party response" in step S8 is determined to be "Y", a call through the call channel of the user is started. . In this case, the user must record and
The message reproduced from the reproduction IC 21 and reconfirmed is verbally transmitted to the other party. Then, when the user performs a call end operation using the keyboard 18 during a call, the CPU 17 determines that "end" in step S9 is "Y", and sends the end information to the base station 3 via the control channel. To end the call with the other party.

If the result of the automatic dialing is that no response from the other party is detected for a certain period of time, it is determined in step S10 whether or not there is a retransmission request based on the operation of the user. And then waits for a predetermined time in step S11. Thereafter, the automatic dial transmission process is executed again in step S7. Note that such automatic dialing is performed a predetermined number of times, for example, 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 cannot make a call, the other party 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 is a base station 3
The user is notified of the fact when it is possible to make a call after entering the area. In this case, the user plays back and confirms the recorded message,
When the stored number is automatically called and the other party answers,
The confirmed message is transmitted to the other party. Therefore,
Even if a call cannot be made at the time of trying to make a call to the other party and the message cannot be transmitted to the other party, the message can be accurately transmitted to the other party when the call can be actually transmitted.

In the case of "N" in step S6, only the message to the other party is recorded on the recording / reproducing IC 21 without storing the other party number in the memory 22, so that the PHS
When the terminal 1 enters the area and is informed that a message recording has been registered and is reproduced, the user may operate the other party's number to make a dial call.

On the other hand, when the PHS terminal 1 enters the area from outside the area of the base station 3, the recording / reproducing IC 21 is notified that there is a message recording, and if the automatic mode is set in the memory 22, step S 3. Is determined to be "N", and automatic dialing based on the other party 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 determines in step S14 that the recording / playback IC 21
To reproduce the message recorded by the user outside the area of the base station 3 or the like. In this case, the reproduced message is transmitted to the base station 3 via the channel codec 15, the modem demodulator 16, and the wireless transmission / reception unit 11 as a radio signal of the communication channel, and further transmitted through the base station 3 and the exchange. Transmitted to the side.

Here, as a result of the automatic dialing,
If the response of the other party is not detected for a certain period of time and the determination in step S13 is "N", processing for stopping automatic dial transmission is performed, and the process waits for a predetermined time in step S16. Thereafter, the process returns to step S12 to execute the automatic dialing process again to call the other party. Also, when there are a plurality of messages to be transmitted to the other party and the remaining messages cannot be transmitted due to a failure of the other terminal during the message transmission, and only about half of the messages to be transmitted can be transmitted (that is, in step S15). (If the judgment is "N")
Performs the process of stopping automatic dialing in the same manner and 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 dialing is performed a predetermined number of times, for example, three times.

As described above, when the PHS terminal 1 is out of the service area of the base station 3 or the like and makes a call to the other party and cannot make a call, the other party 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 is a base station 3
Automatically enters a call based on the other party's number when entering the area, and when the other party answers, automatically reproduces the message and transmits it to the other party. Therefore,
Even when a call cannot be made at the time of trying to make a call to the other party and the message cannot be transmitted to the other party, the message can be accurately transmitted to the other party when the call can be actually transmitted. In addition,
When the transmission to the other party is disabled, the designated transmission time is set in the memory 22, and if the designated transmission time is reached and the PHS terminal 1 is within the range of the base station 3 and the transmission is possible, use it. It is also possible to make a call to the other party by notifying the other party.

[0020]

As described above, according to the present invention, P
If the call cannot be made to the base station on the HS terminal side, a message to be transmitted to the other party is recorded,
When a message can be transmitted to the base station, it is determined whether or not a message has been recorded by the recording means. If a message has been recorded, the user is notified that the PHS terminal is now in a callable state. However, even if a call cannot be made and a message cannot be transmitted to the other party at the time of trying to make a call to the other party, the user is notified when the PHS terminal is ready to make a call. The message can be played back and confirmed, so that the message can be accurately transmitted to the other party.

If it is impossible to make a call to the base station, the telephone number of the other party is registered. If a predetermined operation is performed when the callable state is notified, the message of the recording means is reproduced and , after the end of the reproduction of the message, since the phone number that is registered to be outgoing, it is possible to perform the call sent automatically to the other party even if you forget the phone number of the other party. Also, when outgoing calls are not possible when calling the base station, the other party's phone number and automatic call mode are registered, and when the callable state is notified, the registered phone number is automatically sent,
When the other party answers, the message of the recording means is reproduced and sent to the other party, so that when the PHS terminal is in a state where transmission is possible, the other party can be automatically called and the message can be sent.
