[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication terminal device capable of playing music. In particular, the present invention relates to a portable communication terminal device capable of playing music.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. 2000-308269 discloses a mobile phone device having a music playback function in addition to a normal communication function. A plurality of pieces of music are stored in the music information storage unit, and these pieces of music are displayed on the display, and a music piece to be reproduced can be selected from the music piece and can be heard through the speaker.
[0003]
[Problems to be solved by the invention]
However, in such a conventional mobile phone device with a music playback function, if there is an incoming call during music playback and the incoming call does not include caller ID information, the incoming call history is checked after the music playback ends. However, because the caller ID was unknown, I could not call again.
Therefore, an object of the present invention is to perform communication in which a user does not overlook an incoming call when the incoming call is received while music is being played and the incoming call does not include caller ID information. It is to provide a terminal device.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, a communication terminal device according to the present invention performs communication using a communication line, and includes communication means having caller number information detection means for detecting whether an incoming call includes caller number information; Music playback means for playing back music, and music playback communication control means for controlling either the music playback means or the communication means during music playback by the music playback means. When the communication means receives an incoming call while music is being played by the music playback means, and the caller ID information detection means does not detect the caller ID information for the incoming call, the music playback ends on the spot. When the caller ID information detecting means detects the caller ID information for the incoming call, the music reproduction is continued and the detected caller ID information is stored .
[0005]
According to such a communication terminal device, for an incoming call that does not include caller ID information and cannot be re-called, music playback ends on the spot, so the user simply misses the incoming call. There is nothing.
[0006]
When the music playback communication control means receives an incoming call to the communication means while the music playback means is playing music, and the caller ID information detection means does not detect the caller ID information for the incoming call, It may have an automatic response means for automatically responding to an incoming call after music playback is finished on the spot. This makes it possible to start a call immediately after the music playback is completed.
[0007]
Further, the communication control means during music playback has received an incoming call to the communication means while music is being played back by the music playback means, and the caller ID information detection means did not detect the caller ID information for the incoming call In this case, after the music reproduction is finished on the spot, there may be provided a current incoming call notification means for generating a ringtone and notifying that effect. As a result, it is possible to know that there is an incoming call that does not include the caller ID and cannot be called back during music playback, and it is possible to respond to the incoming call on the spot.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, communication terminal devices according to embodiments of the present invention will be described with reference to the drawings. As the communication terminal device, a terminal device such as a mobile phone, a PHS (Personal Handy Phone), or a PDA (Personal Digital Assistants) can be considered. Here, a description will be given taking PHS as an example. In the following description, the same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted.
[0009]
FIG. 1 is an overall view of the PHS according to the first embodiment. The PHS 1 is provided with an antenna 2 provided at the upper end for transmitting and receiving radio waves, a speaker 8 and a microphone 9 that are used during a call, and an operation that enables call operations such as outgoing and incoming calls and music playback operations. And a display unit 15 that is linked to the operation unit 14 and displays telephone directory data, incoming call information, music information to be reproduced, and the like to the user. In addition, an indicator 25 which is a part of the display unit 15 is provided at the upper part, and similarly, information about an incoming call or the like is visually notified to the user. The operation unit 14 also includes a call key 23 and an end key 24. Further, a headphone jack 19 is further provided on the side surface, and a headphone can be connected to the headphone jack 19 when playing music.
[0010]
In recent years, music information can be easily downloaded as MP3 (MPEG Audio Layer 3) data and MIDI (Musical instrument digital interface) data (Internet distribution) over the Internet. In particular, MP3 data uses a compression technique as described later. It can be used and communicated on the net with high sound quality. In the PHS 1 according to the first embodiment, by providing the memory (semiconductor memory 16) for storing the downloaded music information and the music playback function, the user can carry the cassette tape or MD of the music he / she wants to listen to. You can hear them without them.
[0011]
FIG. 2 is a block diagram showing a schematic configuration of the PHS according to the first embodiment. As described above, the PHS 1 according to the first embodiment has both a communication function (communication means) and a music playback function (music playback means). First, the configuration of the part (communication means) related to the communication function will be described. The PHS 1 transmits or receives radio waves with the antenna 2. At the time of reception, the radio unit 3 down-converts a reception signal having a predetermined frequency captured by the antenna 2 and outputs a π / 4 shift QPSK (Quadrature Phase Shift Keying) signal. When the transmission path is wireless, such as PHS or a mobile phone, it is necessary to place an information signal on a high-frequency radio wave in order to reduce the size of the antenna. However, the wireless unit 3 downconverts the high frequency in this way. Thus, the demodulation processing in the digital modulation / demodulation unit 4 described below is enabled. On the other hand, at the time of transmission, the radio unit 3 up-converts the input π / 4 shift QPSK signal and outputs a transmission signal having a predetermined frequency to the antenna 2.
[0012]
At the time of reception, the digital modulation / demodulation unit 4 performs demodulation processing on the π / 4 shift QPSK signal input from the radio unit 3, extracts a digital signal from the radio wave, and outputs received data. On the other hand, at the time of transmission, the input transmission data is subjected to a modulation process and a π / 4 shift QPSK signal is output, so that an audio signal can be carried on the radio wave.
[0013]
At the time of reception, the TDMA processing unit 5 selects and reconfigures received data input from the digital modulation / demodulation unit 4, that is, data in a downlink slot set in advance from time-division multiplexed data of a plurality of slots, and performs control data and compression Separate into audio data. The separated control data is output to the control unit 11, and the compressed audio data is output to the audio codec unit 6. The data output to the control unit 11 includes caller number information (when the caller is transmitting). This caller ID information is detected by caller ID information detection means that is part of the communication means. On the other hand, at the time of transmission, the input compressed audio data and control data are multiplexed in a preset upstream slot.
[0014]
At the time of reception, the audio codec unit 6 performs decoding processing (including error correction processing) on the audio compression data input from the TDMA processing unit 5 and outputs a received audio signal. On the other hand, at the time of transmission, the input transmission audio signal is subjected to compression encoding processing (including error correction code addition processing) to output compressed audio data.
[0015]
The low-frequency amplifier 7 amplifies the reception audio signal input from the audio codec unit 6, and the speaker 8 outputs sound based on the output audio signal of the low-frequency amplifier 7. The microphone 9 as a transmitter receives an audio signal, and the low frequency amplifier 10 amplifies the audio signal input from the microphone 9 and outputs the amplified audio signal to the audio codec unit 6.
[0016]
The control unit 11 controls the entire system including communication means and music playback means. In addition, the control unit 11 includes a ROM (Read Only Memory) 11a that stores an operation program and the like, and a RAM (Random Access Memory) 11b that stores information on a base station that performs wireless communication. The ROM 11a also stores an operation program for the music playback communication control means for controlling the music playback means and the communication means when playing music by the music playback means.
[0017]
The nonvolatile memory 12 stores various data such as telephone directory data. The ringing tone output unit 13 outputs a predetermined ringing tone under the control of the control unit 11 when an incoming call is received. The predetermined ringing tone includes a telephone bell and an electronic alarm sound, so-called “ringtone” music. The ringing tone output unit 13 can also output vibrations in the manner mode.
[0018]
For example, the operation unit 14 searches for a call key 23 for instructing outgoing calls or responding to incoming calls, an end call key 24 for ending a call, a numeric keypad for entering a telephone number, and telephone directory data. Keys for the user to perform various operations, such as keys used when playing music.
[0019]
The display unit 15 is composed of, for example, a liquid crystal display or the like, and displays an image in monochrome or color. In addition to the system status, the display unit 15 displays the phone book data selected in the search of the phone book data, the telephone number input with the numeric keypad, the music information to be reproduced, and the like. It is also possible to notify the incoming call by blinking the screen or the indicator 25 or performing a predetermined display when the incoming call is received. The nonvolatile memory 12, the ringing tone output unit 13, the operation unit 14, and the display unit 15 are connected to the control unit 11, respectively.
[0020]
Next, a part related to the music playback function (music playback means) of the mobile phone according to the first embodiment will be described. The semiconductor memory 16 is a rewritable and removable semiconductor storage medium. For example, a flash card is applicable. Music data compressed using a compression technique such as MP3 is stored in the semiconductor memory 16. When data is compressed using the MP3 compression technique, the data amount can be reduced to about one-tenth of that of a normal PCM signal even though the deterioration in sound quality is slight. It is possible to secure a sufficient music playback time even when using a small-capacity medium.
[0021]
The MP3 decoder 17 includes a semiconductor circuit such as a DSP (Digital Signal Processor), reads out music data stored in the semiconductor memory 16, expands it to a PCM signal, and outputs it.
[0022]
The headphone amplifier 18 includes a DAC (Digital to Analog Converter) and a low-pass filter, performs digital / analog conversion on the PCM signal input from the MP3 decoder 17 and demodulates the analog signal. Also, the demodulated analog signal is amplified to an amplitude value that can be reproduced at a sufficient volume and output.
[0023]
The headphone jack 19 is an external output terminal. That is, it is a signal terminal for outputting a signal to an external reproduction device such as headphones (not shown) instead of the speaker 8. Normally, when a headphone terminal is connected to the headphone jack 19, the driving of the speaker 8 is stopped. As shown in FIG. 1, both the output signal of the low frequency amplifier 7 and the output signal of the headphone amplifier 18 are input to the headphone jack 19, and the user can listen to them through the headphones. The semiconductor memory 16, the MP3 decoder 17, the headphone amplifier, and the headphone jack 19 are controlled by the control unit 11. Incidentally, the description of the above block diagram corresponds to the first to fourth embodiments.
[0024]
FIG. 3 is a flowchart for explaining the operation when there is an incoming call during music playback in the PHS according to the first embodiment. The PHS 1 according to the first embodiment is an automatic transmission type that automatically transmits an incoming call during music playback to the caller after the music playback ends. In particular, when the caller ID information is not included in the incoming call, the automatic response type is also used in which music playback is terminated on the spot and an automatic response is made. The communication control means at the time of music playback that realizes this flowchart includes proxy response means for sending a message to the caller in response to an incoming call when there is an incoming call during music playback by the music playback means, If there is an incoming call and the caller ID information detecting means does not detect the caller ID information for the incoming call, an automatic response means for automatically responding to the incoming call after the music playback ends, If there is an incoming call, the automatic transmission means that automatically sends the caller to the caller when the music playback ends, and when the music playback ends while there is an incoming call during the music playback And automatic response means for automatically responding to the caller after the music reproduction is finished at the venue. The term means means a software program and hardware for realizing the software program.
[0025]
In step 100, while music is being played back by the music playback means of PHS1, in step 101 it is monitored whether there is an incoming call. If an incoming call is detected, the process proceeds to step 102, and it is determined by the caller ID information detecting means whether or not the incoming call contains caller ID information. If the caller ID information notification is included, the process proceeds to step 103, and the proxy response means makes a proxy response to the incoming call, and then the line is disconnected. As a result, the user can tell the caller that he / she cannot respond because he / she is currently playing music. Further, the operation program may be designed to record a message from the caller. Note that the process of step 103 may be omitted.
[0026]
In step 104, the caller number information of the caller obtained in step 102 is stored, and in step 105, it is monitored whether or not the incoming call is finished. If the incoming call has ended, the process proceeds to step 106, where it is further monitored whether or not the music reproduction has ended. When the music reproduction is completed, the routine proceeds to step 107, where the automatic transmission means automatically transmits the caller number stored in step 104. As described above, since the music is automatically transmitted to the caller when the music reproduction is finished, the user does not have to bother to check the incoming call history and make a call again. It should be noted that the operation program may be designed so that when a user receives an incoming call while playing music of a plurality of songs, the playback ends between the music pieces being played. As a result, music playback can be terminated before all songs are completed, and automatic transmission or the like can be taken. In automatic call, when there is an incoming call, a white list in which the responding opponents are always listed is referred to, and only the opponents on the white list may be automatically sent. From step 108, a telephone line is established by a normal outgoing operation.
[0027]
If the caller ID information is not included in the incoming call in step 102, the process proceeds to step 109, and the music reproduction is forcibly terminated (may be temporarily terminated). Thereafter, the process proceeds to step 111, where the automatic response means automatically answers the incoming call, and in step 112, the call is established. If the caller ID information is not included, the user cannot call back to the caller later, so it is effective that the music playback is interrupted and the procedure for establishing a call is taken. It is. Note that the user may be notified that an incoming call has been received before the automatic response.
[0028]
If it is determined in step 105 that the incoming call has not ended yet, the process proceeds to step 110, where it is determined whether or not music reproduction has ended. If the music reproduction has not ended yet, the process returns to step 105. If the music reproduction has been completed, the process proceeds to step 111, where an automatic response means automatically answers the incoming call, and in step 112, the call is established. At this time, a message to the effect of automatic response may be displayed on the display unit 15 and then the automatic response may be made. In this way, if music playback ends while the incoming call continues, the user can start the call as it is when the music playback ends, so it is necessary to check the incoming call history and make a new call. Absent.
[0029]
Furthermore, if the music reproduction has not yet ended in step 106, the process proceeds to step 113, where it is monitored whether there is another incoming call. If there is another incoming call, the process returns to step 101 and the same procedure as the first incoming call is performed. If there is no other incoming call, the process returns to step 106. Note that the processing of step 113 and step 114 may also be provided in the second embodiment described below.
[0030]
FIG. 4 is a flowchart for explaining the operation when there is an incoming call during music playback in the PHS according to the second embodiment. The PHS 1 according to the second embodiment is a notification type that notifies after an end of music playback that an incoming call has occurred during music playback. In particular, when caller ID information is not included in an incoming call, it is a notification type in which music playback is terminated and notified on the spot. The communication control means at the time of music playback realizing this flowchart is a proxy response means for sending a message to the caller in response to an incoming call when there is an incoming call during music playback by the music playback means, and an incoming call during music playback If there is an incoming call, the incoming call notification means for notifying the caller that there was an incoming call at the end of the music playback, and the incoming caller number information detection means for receiving the incoming call while the music is playing In the case where the user number information is not detected, after the music reproduction is finished on the spot, a current incoming call notification means for generating a ringtone and notifying the fact is included.
[0031]
Since Step 200 to Step 206 are the same as Step 100 to Step 106 of the first embodiment, description thereof will be omitted. When the music reproduction is completed in step 206, the process proceeds to step 207, where the incoming call notification means informs the user that there is an incoming call during the music reproduction using a ringtone or the like. As described above, since the notification is made after the music reproduction is completed, the user can know that there is an incoming call without checking the incoming call history. At the time of notification, the caller number may be displayed on the display unit 15 and the message of the other party recorded in step 203 may be reproduced. From step 208, the normal transmission operation is performed. For this notification, either a bell or vibration by the ringing tone output unit 13 or lighting by the indicator 25 of the display unit 15 is used (hereinafter, the same applies to notification to the user).
[0032]
If the caller ID information is not included in step 202, the process proceeds to step 209 as in the first embodiment, and the music reproduction is forcibly terminated. Thereafter, the process proceeds to step 211, where the current incoming call notification means notifies that there is an incoming call while the user is playing music and that the incoming call is still ongoing. Thereafter, the process proceeds to step 212, where it is determined whether or not the notified user has responded to the incoming call by pressing the call key 23. If the user has responded, the process proceeds to step 213 and the call is established. If no response is received in step 212, the process proceeds to step 214, and it is further determined whether or not the incoming call is terminated. If the incoming call is not yet completed, the process returns to step 212. If the incoming call is terminated, step 215 is performed. To go to the standby state. As in the first embodiment, when the caller ID notification is not made, the user cannot call back to the caller later, so the music playback is interrupted and the response is made on the spot. It is effective to notify the incoming call so as to encourage the user to do so.
[0033]
On the other hand, if the incoming call is not finished yet in step 205, the process proceeds to step 210, where it is determined whether or not the music reproduction is finished. If the music reproduction has not ended yet, the process returns to step 205. If the music reproduction has ended, the process proceeds to step 211, and the subsequent processing is the same as described above. In this way, if music playback ends while the incoming call continues, the user will be notified by a dial tone when the music playback ends. It becomes possible to do.
[0034]
FIG. 5 is a flowchart for explaining the operation when there is an incoming call during music playback in the PHS according to the third embodiment. The PHS 1 according to the third embodiment is a hold-automatic release type in which when a call is received during music playback, the line is connected first, then the state is put on hold, and then the hold is released after the music playback ends. The communication control means at the time of music reproduction realizing the flowchart includes a line connection holding means for automatically answering and connecting a line when there is an incoming call during music reproduction by the music reproducing means and then holding the connection state. Contains. The line connection hold means also has a function of releasing the hold state when the music reproduction is finished.
[0035]
Steps 300 to 302 are the same as steps 100 to 102 in the first embodiment. If it is determined in step 302 that the caller ID information is included in the incoming call, the process proceeds to step 303 where the line connection holding means automatically responds to connect the line, and then the connection state is held. In step 304, a message such as "The user is currently playing music and cannot answer the call because the line is on hold" is transmitted to the caller. Here, BGM or the like may be sent through a line while the caller is waiting. In step 305, it is determined whether or not the music reproduction has been completed. When the music reproduction has been completed, the process proceeds to step 306. After releasing the hold state, the process proceeds to step 307, where the call is started. If the line connection status is put on hold in this way, the user does not need to make another call, and the communication means does not need to perform the line connection operation, so the caller can immediately start a call on the spot. There is an advantage.
[0036]
If the caller ID information is not included in the incoming call in step 302, the process proceeds to step 308. From this point on, either the process from step 109 in the first embodiment or the process from step 209 in the second embodiment is performed. If it is determined in step 305 that music playback has not been completed, the process proceeds to step 309. Further, whether or not the terminal on the caller side is disconnected, that is, whether or not the caller is still in the line connection pending state. Determined. Here, if it is disconnected, the process returns to step 301. If not disconnected, the process returns to step 305.
[0037]
FIG. 6 is a flowchart for explaining the operation when there is an incoming call during music playback in the PHS according to the fourth embodiment. The PHS 1 according to the fourth embodiment is a hold-notification type in which, when an incoming call is received during music playback, the line is connected first, then the state is put on hold, and further, after the music playback is finished, the hold state is notified. is there. The communication control means at the time of music reproduction realizing the flowchart includes a line connection holding means for automatically answering and connecting a line when there is an incoming call during music reproduction by the music reproducing means and then holding the connection state. Contains. The line connection holding means is also provided with a function of notifying that it is in a holding state when the music reproduction ends.
[0038]
Steps 400 to 405, 408, and 409 are the same as steps 300 to 305, 308, and 309 of the third embodiment. In step 405, it is determined whether or not the music playback has been completed. When the music playback is completed, the process proceeds to step 406. After the user is informed that the music is on hold by a dial tone or the like, the process proceeds to step 407. The call is started by manually canceling. Thus, by notifying after the music reproduction is completed, the user can know that there is an incoming call during the music reproduction and that the line connection is currently on hold.
