M131, keypad 141, LCD 142, and buzzer 143 are provided.

The high-frequency section 110, the modulation section 121, and the demodulation section 122 perform modulation / demodulation by １ ／ π shift QPSK and TD
A transmission / reception unit that performs multiplexing and access control by MA (time division multiplexing) / TDD (same frequency time division alternating transmission / reception). The high frequency unit 110 receives radio waves from the radio base station via the antenna 111 periodically. It also has a function of notifying the control unit 130 of the received electric field strength. The modulation unit 121
The sound, the character string, the control data, and the like from the microphone 125, the recording / reproducing unit 123, or the control unit 130 are transmitted for modulation and transmitted to the high frequency unit 110, and the demodulation unit 122 is transmitted from the high frequency unit 110. The received signal is demodulated and passed to the control unit 130, the DTMF receiver 124, or the receiver 126.

The recording / reproducing unit 123 has a recording / reproducing IC,
It has a function of recording audio input from the microphone 125 as a digital signal, and a function of passing audio recorded as a digital signal to the modulation unit 121. The DTMF receiver 124 passes to the control unit 130 what kind of DTMF signal the audio signal received from the demodulation unit 122 has. Since the DTMF signal is generated corresponding to each key of the telephone, the control unit 130
By identifying the DTMF signal sent from the other party by the MF receiver 124, it is possible to know which key the other party has pressed.

A receiver 126 is a speaker, and a keypad 141 accepts user operations, and is a key for dialing 0, 1, 2, etc., similar to a normal telephone, and a key for calling a dedicated function. Etc.
The LCD 142 notifies the user of various information by displaying characters, symbols, and the like on a liquid crystal screen. Here, the dedicated functions include a text message reservation transmission function and a voice message reservation transmission function.

The control unit 130 includes a CPU which executes according to a control program stored in the ROM. The control unit 130 generates various function channels based on the PHS standard in order to execute communication based on an operation of the keypad 141 by a user. Decrypt and control each unit according to the standard protocol of layers 1 to 3. The flash ROM 131 is a non-volatile memory that stores information necessary for realizing each function such as transmission management information described later, and is read and written by the control unit 130. <Operation> Hereinafter, the wireless telephone device 10 having the above-described configuration will be described.
The operation of 0 will be described.

The functional feature of the above-described wireless telephone device 100 is that it has a function of transmitting a text message reservation and a function of transmitting a voice message reservation. First, a text message reservation transmission function will be described. The transmission and reception of the text message can be realized by using, for example, the simple text transmission service of the DDI pocket telephone group, and the description will be made on the assumption that the simple text transmission service is used.

FIG. 2 is a flowchart showing the operation for realizing the text message reservation transmission function. When the user uses the keypad 141 to call the text message reservation transmission function, the control unit 130 displays on the LCD 142 a prompt to input a text message and a telephone number, and inputs a text message by the user (step S301). A telephone number input (step S302) is accepted. The received text message and telephone number are stored in the flash ROM 131 as transmission management information. It should be noted that, in response to the user's input, an echo is displayed on the LCD 142 for display.

Here, the transmission management information stored in the flash ROM 131 will be described. FIG. 3 is a diagram illustrating an example of transmission management information stored in the flash ROM 131. The transmission management information includes a message content 201, a telephone number 202, and a status code 203 indicating a transmission status. The value of the status code is "0" when the transmission is waiting, "1" when the transmission is normally performed, and a predetermined abnormal code value when the transmission is performed but abnormally ends. It is.

FIG. 1 shows that the input message is "B Keikaku @ Jikyou Seyo" and the telephone number is "XXX".
XX01234 ". If the text message to be transmitted and the telephone number of the destination are input by the user, the wireless telephone device 100 starts determining whether or not the wireless telephone device 100 is within the communication range of the wireless base station (step S303). The control unit 130 determines whether or not the communication area is within the communication range based on the information on the received electric field strength from the high frequency unit 110, the identification information of the wireless base station from the demodulation unit 122, and the like. The control unit 130 displays this determination result on the LCD 142 as a symbol indicating an antenna in a communication range, or as a character string "Kengai" in a communication range.

When the control unit 130 determines that the vehicle is not in the service area, it again determines whether the vehicle is in the service area (step S303). That is, the control unit 130 repeats the determination as to whether or not the vehicle is in the communication area until the vehicle enters the communication area. Control unit 130
When the determination that the mobile phone is in the communication area continues for the time T1 (steps S304 and S305), the wireless telephone device 10
It is determined that “0” is stably within the communication area, and a call is made to the telephone number indicated by the transmission management information stored in the flash ROM 131 and a text message is transmitted (step S306). Here, the T1 time is, for example, 5 seconds and is predetermined.

Therefore, in the case of the example of FIG.
As a result, a text message “B Keikaku ヲ コ コ” is sent to the telephone number XXXXXX01234. If there is no response from the transmission partner even after the time T2 elapses after the calling (step S30).
7, S308), exception processing is performed. Here, the response from the transmission partner refers to a change from a state in which the telephone line is disconnected from the transmission partner to a state in which the telephone line is connected to the transmission partner, and the time T2 is, for example, 40 seconds. And is predetermined. In the exception processing, an abnormal code value is set as the status code of the above-described transmission management information.

If there is a response from the transmission partner (step S309), the control unit 130 waits for a reception completion signal sent from the transmission partner, and completes reception from the transmission partner even after a lapse of T3. If no signal is sent,
Exceptional processing is performed (steps S310 and S311). When a reception completion signal is sent from the transmission partner (step S312), a telephone line disconnection sequence is performed according to a prescribed protocol (step S313).
The status code of the transmission management information is set to “1” and the LCD 142
To the effect that transmission has been completed normally (step S31).
4) sound the buzzer 143 to notify the user that the transmission has been completed normally. Here, the T3 time is, for example, 5 seconds and is predetermined.

In the simple character transmission service, the reception completion signal transmitted from the transmission partner is a signal in which a DTMF signal assigned to the "*" key and a DTMF signal assigned to the "#" key are continuous. Stipulated,
The control unit 130 outputs “*” via the DTMF receiver 124.
It can know that the DTMF signal of "#" has been received.

Next, the voice message reservation transmission function will be described. FIG. 4 is a flowchart showing an operation for realizing the voice message reservation transmission function. When the user uses the keypad 141 to call the voice message reservation transmission function, the control unit 130 displays on the LCD 142 a prompt to input a voice message and a telephone number, and inputs a voice message by the user (step S301).
A telephone number input (step S302) is accepted.

The voice message is input to the microphone 125 by the user, and the recording / reproducing unit 123 records the voice message, that is, stores it as a digital signal. In addition, the control unit 130
After receiving the input by the user, the transmission management information for the voice message reservation transmission function is created in the flash ROM 131 in the same manner as the transmission management information for the text message reservation transmission function described above. However, regarding the message content, unlike the transmission management information relating to the text message reservation transmission function, the voice message reservation transmission function receives information for identifying the voice message from the recording / reproducing unit 123 and stores it.

It should be noted that, in response to the user's input of the telephone number, an echo back is displayed on the LCD 142. When the voice message to be transmitted and the telephone number of the destination are input by the user, the control unit 130
A message prompting the user to set the Ta time and the Tb time.
The input of the Ta time and the Tb time by the user is received (step S403).

Here, the Ta time is for performing an exceptional process assuming that transmission has not been completed if the line has been disconnected during the transmission of the voice message and the Ta time has not elapsed since the start of the transmission. The time is for forcibly disconnecting the line when neither the disconnection signal nor the acknowledgment signal is sent from the transmission partner even after the time Tb has elapsed after the start of the voice message transmission.

The control unit 130 also stores the Ta time and the Tb time in the flash ROM 131 as the transmission management information. If the Ta time and the Tb time are set by the user, the wireless telephone device 100 starts determining whether or not the wireless telephone device 100 is within the communication range of the wireless base station (step S404). The control unit 130 determines whether or not the communication area is within the communication range based on the information on the received electric field strength from the high frequency unit 110, the identification information of the wireless base station from the demodulation unit 122, and the like.

When the control unit 130 determines that the vehicle is not in the service area, the control unit 130 determines again whether the vehicle is in the service area (step S404). The control unit 130 determines that it is within the communication range for the time T1 (steps S405 and S405).
406), it is determined that the wireless telephone device 100 is stably within the communication area, and a call is made to the telephone number indicated by the transmission management information stored in the flash ROM 131 (step S407).

If there is no response from the transmitting party even after the elapse of the time T2 after the calling (steps S408 and S409), exception processing is performed. If there is a response from the transmission partner, the control unit 130 notifies the recording / reproduction unit 123 of information for reproducing the voice message based on the transmission management information stored in the flash ROM 131, and The transmission of the voice message is started by reproducing the voice message (step S411).

It should be noted that the recording / playback I
C stores a reminder message such as "Please confirm the message and press the * key" beforehand.
Play this prompt message following the message recorded by the user. Further, the control unit 130 controls the recording / reproducing unit 123 to repeatedly reproduce and transmit a set of the recorded message and the prompt message.

After starting the transmission of the voice message, the control unit 130 detects that the reception acknowledgment signal has been sent from the transmission partner (step S412), or the time Tb has elapsed since the start of the voice message transmission. In this case, a telephone line disconnection sequence is performed according to a prescribed protocol (step S416). Here, the acknowledgment signal sent from the transmission partner is a DTMF signal assigned to the “*” key as shown in the content of the prompt message, and the control unit 130
It can be known that the DTMF signal “*” has been received via the MF receiver 124.

After the transmission of the voice message is started, if the control unit 130 detects that the telephone line has been disconnected by the transmission partner (step S413),
If Ta time has elapsed since the start of the voice message transmission, a telephone line disconnection sequence is performed (step S41).
6) If the Ta time has not elapsed (step S41)
5), exception processing is performed as transmission is not completed.

After the disconnection sequence, the control unit 130 sounds the buzzer 143 to notify the user of the completion of the transmission of the voice message, and displays on the LCD 142 that the transmission has been completed and whether or not a reception confirmation signal has been received. (Step S417). As described above, the radio telephone device 100 is configured such that when a character or voice message or the like is once input by the user, the radio telephone device 100 is originally within the communication range of the radio base station or the radio telephone device 100 When the mobile station moves from outside the communication area of the wireless base station to the communication area, the message is transmitted quickly.

The processing up to the transmission completion display may be continuously performed. As for the transmission completion display, the control unit 130 updates the status code of each transmission management information according to the transmission result, and when a request to display the result is received from the user, the result is determined based on the status code. May be displayed on the LCD 142.

When a plurality of destination telephone numbers are input for one message, a function of transmitting a message to each destination, that is, a so-called broadcast transmission function may be realized. According to the conventional technology, when it is necessary to perform a plurality of transmissions outside the communication range, the user needs to make a plurality of calls to quickly perform the plurality of transmissions after entering the communication range. Although the burden was heavy, if a plurality of wireless telephone devices according to the present invention can be transmitted as described above, the burden on the user as described above is eliminated.
