DETAILED DESCRIPTION OF THE INVENTION
Next, a mobile communication terminal to which the present invention is applied will be described in detail with reference to FIGS. FIG. 1 is a functional block diagram of a mobile communication terminal to which the present invention is applied, and FIG. 2 is a configuration diagram of a temporary storage area for transmission data provided in the memory of the mobile communication terminal to which the present invention is applied. 3 to 6 are process flow diagrams showing an operation example of the mobile communication terminal to which the present invention is applied.
[0009]
As shown in FIG. 1, a mobile communication terminal according to the present invention includes a CPU 101, an RF unit 103, a baseband 105, a ROM 107, a RAM 109, an antenna 125, a display unit 111, a key 113, a codec 115, an MIC (microphone) 117, An SP (speaker) 119 and a vibration motor 123 are provided. The CPU 101 controls the entire mobile communication terminal.
The RF unit 103 transmits an audio signal, a data signal (including message information), a control signal, or the like from the antenna 125, or receives an audio signal, a data signal, a control signal, or the like from the antenna 125. The baseband unit 105 modulates and demodulates transmission / reception signals, and the codec 115 performs A / D conversion (analog-digital conversion) and D / A conversion (digital-analog conversion). The MIC 117 corresponds to an audio input unit, and the SP 119 corresponds to an audio output unit.
[0010]
Further, the CPU 101 operates according to a control signal from the key 113 and the baseband 105 in accordance with a program described in the ROM 107, and executes each function of the main body. The ROM 107 also stores system data such as terminal information. The CPU 101 is also connected to the RAM 109, and stores history data of outgoing / incoming messages (transmission / reception history and transmitted / received message information), data registered or set by a telephone directory function, and the like. The vibration motor 123 notifies the incoming call by vibrating the main body. Specifically, when the user does not want to emit an audible sound from the main body in a public place such as a train, the main body of the mobile communication terminal is vibrated using the vibration motor 123 to notify the user of necessary information. ing.
In addition to the information provided to the main body, the display unit 111 displays functions and setting items provided in the main body. The key 113 includes a dial button for inputting a telephone number of a called party telephone, an off-hook key for making a call or a response, or a function key for setting various functions.
[0011]
FIG. 2 is a configuration diagram of a temporary storage area for transmission data provided in the RAM 109. The character mail using unit 201 for storing character data is variable in the range of 0 (bit) to the maximum transmission data size M (bit), and the attached file using unit 203 for storing audio data, image data, etc. is also 0 (bit). It is variable within the range of maximum transmission data size M (bit). The upper limit of both is the difference between the maximum transmission data size M and 201 when 201 is selected as transmission data first, and the maximum transmission data size M when 203 is selected as transmission data first. It is determined by the difference value from 203.
[0012]
FIG. 3 is an operation flowchart in a case where an attached file is first selected and then a text mail is created. When image / sound data as an attached file is selected in step 301, the data size (A) of the selected attached file is stored (step 303). Next, the file size (I), which is the sum of the required header size (h) and the data size (A), is subtracted from the maximum transmission data size (the maximum number of bytes that can be transmitted in FIG. 3), and the remaining transmission is possible. Substitute into the data size (l) (step 305). In step 307, it is confirmed whether or not the file size (I) of the transmission data exceeds the maximum transmission data size.
[0013]
If it exceeds, the selection of the attached file is canceled and a message to that effect is displayed on the screen (step 323). The file size (I) of the transmission data at this time is a value obtained by subtracting the data size (A) of the attached file selected in step 301, and the remaining transmittable data size (l) is also recalculated. After the cancellation, the user selects whether to reselect the attached file or shift to character creation (step 321). When the attachment file is selected again, the process returns to step 301 and the above process is repeated. If the shift to character creation is selected, the number of transmittable characters is calculated from the recalculated remaining transmittable data size (l) (step 311).
[0014]
If the file size (I) of the transmission data does not exceed the maximum transmission data size in step 307, the process proceeds to the next process as it is, and the user is allowed to select whether or not to create characters (step 309). When character creation is not performed, a content confirmation screen is displayed (step 325), and a user input of transmission OK / transmission NG is waited (step 327). If the transmission is OK, the process proceeds to the transmission process (step 329), and the process ends (step 331). If the transmission is NG, the process returns to step 321. When creating characters, the number of transmittable characters is calculated from the remaining transmittable data size (l) (step 311).
[0015]
The number of transmittable characters calculated in step 311 is displayed on the screen (step 313). When the input of characters is confirmed (step 315), the number of transmittable characters is recalculated and displayed (step 317). The above processing is repeated during character editing, and when the end of character input is confirmed (step 319), a content confirmation screen is displayed (step 325), and a user input of transmission OK / transmission NG is waited (step 327). . If the transmission is OK, the process proceeds to the transmission process (step 329), and the process ends (step 331). If the transmission is NG, the process returns to step 321.
[0016]
FIG. 4 is an operation flowchart in the case where a text mail is first created and then the recorded voice data is transmitted as an attached file.
When the text mail is created in step 401, the data size (A) of the created text mail is stored (step 403). Next, transmission is possible by subtracting the transmission data size (I), which is the sum of the required header size (h) and data size (A), from the maximum transmission data size (maximum number of bytes that can be transmitted in FIG. 4). Substitute into the remaining data size (l) (step 405). In step 407, it is confirmed whether or not the remaining transmittable data size (l) is present, that is, whether or not the transmission data size (I) exceeds the maximum transmission data size.
[0017]
If there is no remaining data size (l) that can be transmitted, that fact is displayed on the screen (step 421), a content confirmation screen is displayed (step 423), and a user input for transmission OK / transmission NG is waited (step 421). 427). If the transmission is OK, the process proceeds to the transmission process (step 429), and the process ends (step 431). If the transmission is NG, the process proceeds to step 425. If the character creation is performed again, the process returns to step 401. In this case, recording cannot be selected because there is no remaining data size (l) that can be transmitted.
[0018]
If there is a remaining transmittable data size (l), the recordable time is calculated from the size (l), and the calculation result is displayed on the screen (step 411). Next, it is confirmed whether or not to record the voice to be attached (step 413), and if not attached, a content confirmation screen is displayed (step 423), and then a user input of transmission OK / transmission NG is waited (step 427). ). If the transmission is OK, the process proceeds to the transmission process (step 429), and the process ends (step 431). If the transmission is NG, the process proceeds to step 425.
[0019]
When attaching audio data, the process proceeds to a recording start process (step 415), a recording timer is started (step 415), and a recording process is performed (step 417). When a recording timer time-out or an instruction to end recording is received (step 418), it is confirmed whether or not to record again (step 419).
If recording is not performed again, a content confirmation screen is displayed (step 423), and a user input for transmission OK / transmission NG is waited (step 427). If the transmission is OK, the process proceeds to the transmission process (step 429), and the process ends (step 431). If the transmission is NG, the process proceeds to step 425. When re-recording, the process returns to the recording start process (step 415).
[0020]
Details of the recording process (step 417 in FIG. 4) will be described with reference to FIGS. Here, FIG. 5 shows the first embodiment, and FIG. 6 shows the second embodiment.
In FIG. 5, a recording screen is displayed at step 501. Next, the recording start time is notified to the user by displaying a countdown screen on the display unit 111, outputting a countdown sound from the speaker 119, using a countdown vibration by the vibration motor 123, and the like (step 503). When the recording start time comes, a recording start screen is displayed on the display unit 111 (step 505), and the remaining time until the end of recording is displayed as a countdown screen (step 507). Recording time-out or recording end instruction is received and recording ends (step 509).
[0021]
In FIG. 6, a recording screen is displayed at step 601. Sound / silence is detected by a DSP (digital signal processor) or the like, and recording is started when it is detected that the sound has shifted from silence to sound (step 603). When recording is started, a recording start screen is displayed on the display unit 111 (step 605), and the remaining time until the end of recording is displayed as a countdown screen (step 607). Recording time-out or recording end instruction is received and recording ends (step 609).
Although the embodiment of the present invention has been described above, it is obvious that the combination of message data, the transmission procedure, and the like are not limited to those described above.
Furthermore, although the case where the present invention is applied to a mobile communication terminal has been described above, the present invention is not limited to a mobile communication terminal, and is not limited to a communication terminal (such as a home videophone) capable of transmitting / receiving character, voice, and image data. It is clear that can also be applied.
