[0002]

2. Description of the Related Art In a communication terminal such as a telephone, there is a case that a request arises that it is desired to transmit the same voice information to a plurality of parties, that is, to perform so-called broadcast communication. When performing broadcast communication, if the network operator to which the communication terminal to be used provides a broadcast service, the service is used. On the other hand, the operations from dialing to calling and ending are repeated.

[0005] Here, the flow of operation for performing broadcast communication will be described with reference to FIG. FIG. 9 is a flowchart showing a flow of a conventional broadcast communication operation.

When the network operator provides a broadcast service, when an operation is started as shown in FIG. 9A (step 801), first, a call is made and a center (the operator side) is called. (Step 802). Subsequently, a message as voice information to be broadcasted is recorded (step 803), a broadcast destination is set by key input (step 804), and a call end operation is performed (step 805), and broadcast communication is performed. Is completed (step 806).

[0005] If the network operator does not provide the broadcast service or does not use the broadcast service even if provided, the operation is started as shown in FIG. 9B (step 851). First, a call is made to the first broadcast destination (step 852). Thereafter, necessary information is transmitted by telephone call (step 853), and an operation for ending the call is performed (step 854). The operations of steps 852 to 854 are performed for all the broadcast destinations (step 855).
When the call to all the members is completed (step 8)
If YES in step 55, the broadcast operation ends (step 856).

[0006] As described above, when performing the broadcast communication without using the broadcast service provided by the network operator, a lot of labor and time are required.

In addition, network operators do not always provide a broadcast service, and many people cannot receive the broadcast service. Therefore, when performing the broadcast communication, it is necessary for the transmitting side of the voice information to perform each operation of dialing, talking, and ending the call to each of the plurality of parties.

Accordingly, the present invention provides a communication terminal capable of sequentially broadcasting voice information only by local operation on the communication terminal side without depending on the presence or absence of a broadcast service provided by a network operator and its specifications. It is intended to provide a device.

g / Digital Converter) 152, speaker 153, D / A (Digital / Analog)
(Converter) 154, and establishes a wireless line with the base station 2 to perform a call or the like.

The CPU 10 operates based on a program stored in the program memory 11 and controls each unit. The program memory 11 is a memory for storing a program for causing the CPU 10 to operate.
2 transmits and receives wireless signals to and from the base station 2. The operation panel 13 includes input keys for setting and dialing. The display unit 14 displays various information such as telephone numbers and operation instructions, and includes a liquid crystal panel.

The DSP 15 performs processing such as voice coding on the voice input from the microphone 151 and converted into a digital signal by the A / D 152, and sends out the processed voice to the radio unit 12 and the voice data storage unit 17. The unit 12 decodes the received voice-encoded signal into a digital voice signal. The digital audio signal decoded by the DSP 15 is converted into an analog audio signal by the D / A 154, and is output from the speaker 153 as audio.

The signal detector 16 detects a tone signal from the signal received by the radio unit 12 and
Stores audio data input and converted from the microphone 151 and audio data registered in advance. The telephone number temporary storage unit 18 temporarily stores a telephone number to be a broadcast destination, and the telephone directory storage unit 19 classifies and stores a plurality of telephone numbers as necessary.

Next, the operation of the wireless telephone terminal 1 for performing broadcast communication will be described. First, the user inputs voice information (message) for performing broadcast communication from the microphone 151. The voice input to the microphone 151 is converted to a digital signal by the A / D 152, compressed and coded by the DSP 15 in a format that matches the voice coding system specified by the carrier, and stored in the voice data storage unit 17. You.

Subsequently, the CPU 10 stores the program memory 1
The user is prompted to input a telephone number to be allocated to the voice data previously stored in the voice data storage unit 17 based on the program stored in the program stored in 1. The instruction for inputting the telephone number is performed by displaying on the display unit 14. When the user inputs a telephone number from the operation panel 13 according to a telephone number input instruction, the telephone number is sequentially stored in the telephone number temporary storage unit 18. The stored telephone number is associated with voice data stored in the voice data storage unit 17 as shown in FIG. Also,
The telephone number input by the user may be directly input from the operation panel 13 or a telephone number stored in the telephone directory storage unit 19 may be selected (the telephone number is also selected from the operation panel 13).

When the above setting is completed and the user instructs the broadcast transmission from the operation panel 13, the CPU 10 starts the broadcast transmission processing, and if the communication with the base station 2 is possible (so-called service area). A call is made to one of the telephone numbers stored in the telephone number temporary storage unit 18, and the DSP 15 calls the voice data stored in the voice data storage unit 17 and develops it into a transmission burst. This is transmitted by the radio unit 12 to the base station. When the transmission is completed, a call termination process is performed, and the same process is performed for another telephone number stored in the telephone number temporary storage unit 18. When the same processing is performed for all the telephone numbers stored in the telephone number temporary storage unit 18, the broadcast transmission processing ends.

After the completion of the broadcast transmission processing, the CPU
Reference numeral 10 traces the history of whether or not voice data has been notified to each telephone number, and displays the result on the display unit 14. The history of notification / non-delivery for each telephone number is as shown in FIG. This is achieved by providing an area for transmission history in the temporary storage unit 18 together with a storage area for each telephone number.

With the above operation, the radio telephone terminal 1 can record the voice, sequentially broadcast the voice to a plurality of telephone numbers, and display the result of the sequential broadcast.

Next, the operation of the wireless telephone terminal 1 will be described in detail with reference to FIGS. 3 to 6 are flowcharts showing the flow of the operation of the wireless telephone terminal 1.

When the radio telephone device 1 starts the broadcast process (step 101), the prior data acquisition process (step 102), which will be described later, and the broadcast transmission process (step 10).
3) The transmission result display process (step 104) is sequentially performed, and the process ends (step 105).

Here, the preliminary data acquisition processing in step 102 will be described with reference to FIG. The pre-data acquisition process is started (step 201), and when voice recording is started by the operation of the operation panel 13 by the user (YES in step 202), the A / D 152 converts the voice into a digital signal and the DSP 15 compresses the voice. Encoding is performed (step 203), and this is stored in the audio data storage unit 17.
Write to. The compression encoding of the voice and the writing to the voice data storage unit 17 are continued until the recording ends (NO in step 205), and when the recording ends (step 2).
(05: YES), the pointer n indicating the address of the writing position in the telephone number temporary storage unit 18 is initialized to 1 (step 206).

Subsequently, the user waits until the telephone number of the broadcast destination is directly input by the operation of the operation panel 13 or the telephone number stored in the telephone directory storage unit 19 is selected (NO in step 207, If the telephone number is directly input (NO in step 208),
S), the telephone number (n) is set as the directly input telephone number (step 209), and the telephone number (n) is written into the telephone number temporary storage unit 18 (step 210).

On the other hand, the telephone number of the broadcast destination is stored in the telephone directory storage unit 1.
9 (step 208), the telephone number (n) is set as the selected telephone number (step 211), and the telephone number temporary storage unit 18 is selected.
(Step 210).

Thereafter, if the user does not perform an operation to end the input of the telephone number (NO in step 212), the pointer n of the telephone number temporary storage unit 18 is shifted to n + 1 (step 213), and the process returns to step 207. The same processing is performed.

These processes are repeated, and when the user performs the operation of terminating the input of the telephone number (step 212).
YES), the pre-data acquisition process ends (step 214).

Next, the sequential broadcast transmission processing of step 103 will be described with reference to FIG. When the broadcast transmission processing is sequentially started (step 301), the user performs a transmission start operation (YES in step 302), and the wireless telephone terminal 1 is within a communication area where communication with the base station 2 is possible. If (YES in step 303), the pointer n indicating the address of the read position of the telephone number temporary storage unit 18 is set to 1
(Step 304).

Subsequently, the telephone number (n) indicated by the pointer n
(Step 305), and waits for an incoming call of the called side (telephone number (n)) for a predetermined time (step 30).
NO at 6 and NO at step 307). If the called party receives a call within a predetermined time (YES in step 306),
The audio data stored in the audio data storage unit 17 is
The voice message expanded into the transmission burst in SP15 is transmitted from the radio unit 12 to the base station 2 (step 308). If the transmission is successful (YES in step 309), the call is terminated (step 310), and the telephone number is entered. Temporary storage unit 1
8 "Transmission OK" is stored in the transmission result storage area of the telephone number (n).
Is written (step 311).

On the other hand, if the called party does not receive a call within a predetermined time and a timeout occurs (YES in step 307),
If the transmission of the voice message fails (step 3
09 (NO in step 09), the line is disconnected (step 312), and "transmission NG" is written in the transmission result storage area of the telephone number (n) in the telephone number temporary storage unit 18 (step 313).

Next, if the transmission attempt for all the telephone numbers stored in the telephone number temporary storage unit 18 has not been completed (NO in step 314), the pointer n of the telephone number temporary storage unit 18 is set to n + 1. (Step 31)
5) Returning to step 305 and repeating the same processing, and if the transmission trial for all telephone numbers is completed (step 3)
Then, the broadcast transmission process is sequentially terminated (step 316).

Next, the transmission result display processing in step 105 will be described with reference to FIG. When the transmission result processing is started (step 401), the CPU 10 analyzes the transmission history based on the transmission result stored in the telephone number temporary storage unit 18 (step 402), and all the transmission results are “transmission OK”. "(Y at step 403)
ES), "Transmission OK" is displayed on the display unit 14 (step 404).

On the other hand, if any of the transmission results is “transmission NG”
(NO in step 403), the display unit 1
In step 4, “number of NG / total number” is displayed together with “NG of transmission” (step 405), and each telephone number that has become transmission NG based on the operation of the operation panel 13 by the user is displayed (step 406).

Here, if there is an operation to end the display by the user (YES in step 407), and if there is an instruction to hold the stored data (YES in step 408), the transmission result display process is terminated (step 413).

On the other hand, if the user instructs to erase the stored data (NO in step 408), and if the instruction to erase the audio data is issued (YES in step 409), the audio data is deleted from the audio data storage unit 17. (Step 4
10) If it is instructed to delete the broadcast destination telephone number (YES in step 411), the telephone number temporary storage unit 18
Then, the telephone number group is deleted from (step 412), and the transmission result display process ends (step 413).

In this embodiment, speech is encoded using a DSP. However, the speech encoding may be performed using a speech synthesis IC having the same function. It is not always necessary to use those shown here.

Also, in this embodiment, the user has recorded a voice message to be broadcasted, but by inserting a fixed message such as "this message is broadcast" at the beginning of the message, It is also possible to avoid confusion on the side (such as misunderstanding that the user himself is speaking directly).
Furthermore, if a plurality of types of fixed messages are stored in advance, broadcast can be performed without recording if the message is simple. This fixed message is stored in the voice data storage unit 17 in advance, and can be selected from the operation panel 13 so that it can be handled in the same manner as the above-described method.

Next, the second communication terminal apparatus according to the present invention will be described.
An example will be described. In the first embodiment described above, during the broadcast transmission processing (see FIG. 5), if the called party receives a call and the voice message has been successfully transmitted, "transmission OK"; otherwise, Although “transmission NG” is described, even if “transmission OK” is selected, the message is not necessarily transmitted to the other party. For example, if the answering machine function is used in the telephone terminal of the called side, the transmitted message is recorded on the called side, so that the other party does not necessarily hear it. Therefore, in the second embodiment, a case will be described with reference to FIG. 7 where it is configured to confirm whether or not the called party has heard the message. The second embodiment is different from the first embodiment only in that the broadcast transmission processing is sequentially different, so that the description of the other parts is omitted.

When the broadcast transmission process is sequentially started (step 501), the user performs an operation of starting transmission (YES in step 502), and the wireless telephone terminal 1 can communicate with the base station 2. If within range (step 503
YES), the pointer n indicating the address of the reading position of the telephone number temporary storage unit 18 is initialized to 1 (step 504).

Subsequently, the telephone number (n) indicated by the pointer n
(Step 505), and waits for an incoming call of the called side (telephone number (n)) for a predetermined time (step 50).
NO at 6 and NO at step 507). Here, if the called party receives a call within a predetermined time (YES in step 506),
The audio data stored in the audio data storage unit 17 is
The voice message expanded into the transmission burst in SP15 is transmitted from the radio unit 12 to the base station 2 (step 508), and when the message is subsequently confirmed, an instruction is given to press a predetermined key, for example, a "#" key. A fixed message is transmitted (step 509).

If the transmission is successful (YE at step 510)
S), waiting for a confirmation sound (by pressing the “#” key) for a predetermined time (NO in step 511, NO in step 512), and when the signal detection unit 16 detects the reception of the confirmation sound within a predetermined time ( (YES in step 511), terminates the call (step 513), and writes "transmission OK, confirmed" in the transmission result storage area of telephone number (n) in telephone number temporary storage unit 18 (step 514). If the signal detector 16 does not detect the receipt of the confirmation sound within a predetermined time and the timeout occurs (YES in step 512), the call is terminated (step 515), and the telephone number temporary storage 1
In the transmission result storage area of the telephone number (n) of No. 8, "Transmission OK,
"Unconfirmed" is written (step 516).

On the other hand, if the called party does not receive a call within a predetermined time and a timeout occurs (YES in step 507),
If the transmission of the voice message fails (step 5
(NO at 10), the line is disconnected (step 517), and "transmission NG" is written in the transmission result storage area of the telephone number (n) in the telephone number temporary storage unit 18 (step 518).

Next, if the transmission attempt for all the telephone numbers stored in the telephone number temporary storage unit 18 is not completed (NO in step 519), the pointer n of the telephone number temporary storage unit 18 is set to n + 1. (Step 52)
0), the process returns to step 505 and the same process is repeated, and if the transmission trial for all telephone numbers is completed (step 5)
19 (YES), the broadcast transmission processing is sequentially terminated (step 521).

Although the description is omitted here, when the sequential broadcast transmission processing in the second embodiment is adopted,
When displaying the transmission result, the telephone numbers are classified and displayed in three ways: "transmission OK, confirmed", "transmission OK, unconfirmed", and "transmission NG".

Next, the third communication terminal apparatus according to the present invention will be described.
Will be described with reference to FIG. The third above
In the third embodiment, only "transmission OK" and "transmission NG" are displayed in the transmission result display processing (see FIG. 6). However, in the third embodiment, "transmission NG" is displayed. A case in which a message can be retransmitted to a changed telephone number will be described. Note that the third embodiment differs from the first embodiment only in the transmission result display processing, so that the description of the other parts will be omitted.

When the transmission result processing is started (step 6)
01), the CPU 10 analyzes the transmission history based on the transmission result stored in the telephone number temporary storage unit 18 (step 602), and when all the transmission results are “transmission OK” (step 603). YES), display unit 14
"Transmission OK" is displayed (step 604).

On the other hand, if any of the transmission results is “transmission NG”
Is displayed (NO in step 603), the display unit 1
4, "NG / Total" is displayed together with "NG transmitted" (step 605), and each telephone number which has become a transmission NG based on the operation of the operation panel 13 by the user is displayed (step 606).

If the user has performed an operation of terminating the display (YES in step 607), the user is asked to determine whether or not to perform retransmission for "transmission NG". Is instructed (YES in step 608), the CPU 10 sets a new telephone number group consisting only of telephone numbers that have become “transmission NG” in the telephone number temporary storage unit 18 (step 608). 609), if there is a user edit (addition of a new phone number or deletion of an existing phone number) to this phone number group (YES in step 610), the user edits the phone number (step 611). If not, the process proceeds to the broadcast transmission process as it is (NO in step 610) (step 612).

On the other hand, if there is no retransmission instruction for “transmission NG” by the user (NO in step 608), and if there is an instruction to hold the stored data (YES in step 613), the transmission result display processing is terminated (step 618). . If the user instructs to delete the stored data (NO in step 613) and instructs to delete the audio data (YES in step 614), the audio data storage unit 1
7 is deleted (step 615), and if deletion of the telephone number of the broadcast destination is instructed (step 616).
YES), the telephone number group is deleted from the telephone number temporary storage unit 18 (step 617), and the transmission result display processing ends (step 618).

As a result of the analysis of the transmission history in step 602, the transmission results for all telephone numbers are "transmission O
In the case of "K", after the display of "transmission OK" is completed (YES in step 607), the process proceeds to step 613 without skipping the retransmission instruction to the user (skips step 608).

[0055]

As described above, according to the present invention, a voice message to be broadcasted is recorded,
Since the telephone number of the broadcast destination is set and the voice message is sequentially transmitted to the set telephone number,
Broadcasting to a plurality of destinations can be performed by a simple operation regardless of the presence or absence of the broadcasting service by the network operator.

Since the transmission history is analyzed and the arrival and non-delivery of the transmitted voice message are displayed, the user can immediately know the arrival status of the message after the end of the broadcast transmission processing. .
