DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a communication terminal apparatus according to an embodiment 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 Handyphone System), a PDA (Personal Digital Assistant), and the like can be considered, but here, the PHS will be described as an example.
[0011]
FIG. 1 is a block diagram showing a schematic configuration of a PHS according to an embodiment of the present invention. The PHS according to the present embodiment has both a communication function and a music playback function. First, the configuration of the portion 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 of a predetermined frequency captured by the antenna 2 and outputs a π / 4 shift QPSK (Quadrature Phase Shift Keying) signal. On the other hand, at the time of transmission, the input π / 4 shift QPSK signal is up-converted, and a transmission signal having a predetermined frequency is output to the antenna 2.
[0012]
At the time of reception, the digital modulation / demodulation unit 4 demodulates the π / 4 shift QPSK signal input from the radio unit 3 and outputs received data. On the other hand, at the time of transmission, the input transmission data is modulated, and a π / 4 shift QPSK signal is output.
[0013]
At the time of reception, the TDMA processing unit 5 selects reception 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 separates it into control data and compressed audio data To do. 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. In addition, the control unit 11 includes a ROM (Read Only Memory) 11 a in which an operation program and the like are written, and a RAM (Random Access Memory) 11 b that stores information on a base station that performs wireless communication. The nonvolatile memory 12 stores various data such as telephone directory data.
[0017]
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]
The operation unit 14 is, for example, a call key for instructing outgoing calls or responding to incoming calls, an end call key for ending a call, a numeric keypad for entering a telephone number, and a key for searching telephone book data. Etc., and keys for the user to perform various operations.
[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 phone number input with the numeric keypad, and the like. Further, when an incoming call is received, it is possible to notify the incoming call by blinking the screen or performing a predetermined display. 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, the part concerning the music reproduction function of the PHS according to the present 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 (MPEG Audio Layer 3) 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.
[0024]
Next, the operation of the PHS according to the embodiment of the present invention configured as described above will be described. In the present embodiment, when an incoming call is received during music playback, different measures are taken depending on the incoming call timing as follows. In other words, the process for the incoming call is performed based on the reproduction time of the music data that has been reproduced at the time of the incoming call or the reproduction time of the music data that has not been reproduced at the time of the incoming call. Alternatively, the incoming call processing is performed based on the data amount of music data already reproduced at the time of incoming call or the data amount of music data that has not been reproduced at the time of incoming call.
[0025]
Specifically, when there is an incoming call within a predetermined time after music playback starts, any one of A-1 to A-3 is performed.
A-1: When an incoming call is received, an automatic connection is established to establish a call state.
A-2: When an incoming call is received, an incoming call notification is performed, and when the user is off-hooked, a call state is set.
A-3: When an incoming call is received, an automatic response message is transmitted, and then automatic disconnection is performed. Music playback continues.
[0026]
Further, when there is an incoming call within a predetermined time before the end of music reproduction, any one of B-1 to B-5 is performed.
B-1: Automatically responds to incoming calls and keeps on hold until the music ends. When the song is finished, the hold is canceled automatically or manually, and a call state is established.
B-2: When an incoming call is received, an incoming call notification is performed. If the user goes off-hook, the call state is established.
B-3: When an incoming call is received, an automatic connection is established to establish a call state.
B-4: Even if there is an incoming call, the incoming call notification is not made until the music ends. If the incoming call still continues when the song ends, an incoming call notification is performed.
B-5: Automatically responds to incoming calls, sends a message, and automatically disconnects.
[0027]
In the present embodiment, the correspondence can be determined by the combination of A-1 to A-3 and B-1 to B-5. For example, when the incoming call is received within a predetermined time from the start of music playback and when the incoming call is received within a predetermined time before the end of music playback, the correspondence shown in FIG. can do. That is, when there is an incoming call in the first half of the song, a process of “A-1: automatically connect to receive call when incoming” is performed, and when an incoming call is received in the second half of the song, “B-1 : Automatically responds when an incoming call is made, and is put on hold until the song is finished. When the song is finished, the hold is automatically or manually released and the call state is set.
[0028]
2 to 10 are flowcharts showing the operation of the PHS according to the present embodiment. In FIG. 2, when the user is playing music, it is always monitored whether there is an incoming call (step S1). If there is no incoming call, the determination in step S1 is repeated. If there is an incoming call, it is determined whether the telephone number of the caller is registered in the telephone directory (step S2). Here, it is assumed that a caller ID notification is received from the caller. The determination in step S2 is performed only when (1) the calling number matches the number registered in the telephone directory. (2) The telephone number determined in advance so that the calling number has priority over the call. Operates only when the number matches the number registered in the white list. (3) Operates when there is no caller ID notification. (4) Caller ID is registered in the phone book. (5) Operates only for incoming calls from numbers not registered in the white list, (6) Black list which is a list of telephone numbers predetermined so as not to make a call Variations such as operating only for incoming calls from numbers that are not registered in the network are conceivable.
[0029]
If the calling number is not registered in the phone book in step S2, the process proceeds to the determination in step S1 without performing the operation for incoming calls, and if it is registered in the phone book, in the first half of the currently playing song. It is determined whether or not there is (step S3). The “first half of the song” may be the first half of the song, or may be within a predetermined time, for example, within one minute after the performance starts. In the case of the first half of the song, the process proceeds to each operation shown in FIGS. First, when taking the correspondence of A-1 shown in FIG. 3, the display unit 15 displays “automatic connection because incoming call” (step S4). At this time, notification by outputting voice data may be performed. Next, the reproduction of music is stopped (step S5) and automatically connected (step S6). Thereby, a call is established.
[0030]
In step S3, when the first half of the song is A-2, the music playback is stopped and the incoming call is notified (step S7). Next, it is determined whether or not the user has been off-hooked (step S8). If not off-hooked, it is determined whether or not the call has been terminated (step S9). When the call is finished, the call is finished. When the call is not finished, the determination in step S8 is repeated. In step S8, when the user goes off-hook, a call is established.
[0031]
In step S3, if the first half of the song corresponds to A-3, it automatically connects (step S10) and, for example, “Since we cannot answer the phone, please call again later. Is sent (step S11). If there is a message from the caller, the message is recorded (step S11). Next, it is determined whether the recording from the calling party is completed or the line is disconnected (step S12). If the recording is not completed or the line is not disconnected, this determination is repeated. When recording is completed or the line is disconnected, the process ends. Note that, when taking the correspondence of A-3, the reproduction of the music data is continued.
[0032]
On the other hand, if it is not the first half of the song in step S3, it is determined whether it is the second half of the song being played (step S13). The “second half of the song” may be the latter half of the song or may be within one minute before the end of the song. If it is not the latter half of the song in step S13, other processing is performed (step S14). Note that the other processing in step S14 is assumed to correspond to the case where an incoming call is received at a timing that does not fall within a predetermined time from the start of performance or within a predetermined time before the end of performance as the first half of the music. For example, an incoming call may be answered, or after automatic connection, a message may be sent and music playback continued.
[0033]
If it is the latter half of the song in step S13, the process proceeds to each operation shown in FIGS. First, when taking the correspondence of B-1 shown in FIG. 6, an automatic response is made to the caller, and the hold is set (step S15). Next, it is determined whether or not the currently reproduced music has been completed (step S16). If it has not been completed, it is determined whether or not the line is maintained (step S17). If the line is maintained, the process proceeds to step S16. If the line is not maintained, the hold setting is canceled (step S18), and the process proceeds to step S1 shown in FIG.
[0034]
In step S16, when the song being played is finished, a notification that the call is to be transferred is notified (step S19), and the hold is released automatically or manually by the user (step S20), and the call is established.
[0035]
In step S13, if the second half of the music and B-2 is taken, the music playback is stopped and the incoming call notification is given (step S21). Next, it is determined whether or not the user has gone off-hook (step S22). If the user does not go off-hook, it is determined whether or not the call has ended (step S23). If the call has not ended, the process proceeds to step S22, and if the call has ended, the process ends. On the other hand, if the user goes off-hook in step S22, a call is established.
[0036]
Further, in step S13, when the second half of the music and B-3 is taken, a message to the effect that "there is an incoming call and an automatic connection" is displayed on the display unit 15 (step S24). At this time, notification by outputting voice data may be performed. Next, the reproduction of music is stopped (step S25) and automatically connected (step S26). Thereby, a call is established.
[0037]
Further, in step S13, when the second half of the music and B-4 is taken, it is determined whether or not the music being played has ended (step S27). It is determined whether or not the processing has been completed (step S28). If the call is not finished, the process proceeds to step S27, and if the call is finished, the process is finished. If it is determined in step S27 that the song being played has ended, it is determined whether the incoming call is continuing (step S29). If the incoming call is not continued, the process is terminated. If the incoming call is continued, an incoming call notification is performed (step S30). Next, it is determined whether or not the user has been off-hooked (step S31). If not off-hooked, it is determined whether or not the call has been terminated (step S32). If the call has not ended, the process proceeds to step S31, and if the call has ended, the process ends. In step S31, when the user goes off-hook, a call is established.
[0038]
In step S13, if it is the second half of the song and B-5 is taken, it will automatically connect (step S33) and, for example, “Since we cannot answer the call, please call again later. "Or the like is sent (step S34). Next, it is determined whether message transmission has been completed or the line has been disconnected (step S35). If message transmission has not been completed or the line has not been disconnected, this determination is repeated. When the message transmission is completed or the line is disconnected, the process ends. Note that in the case of taking the correspondence of B-3, the reproduction of music data is continued.
[0039]
As described above, according to the PHS according to the present embodiment, when an incoming call is detected during music playback, the playback time of music data already played at the time of incoming call or the playback time of music data that has not been played back at the time of incoming call Therefore, priority is given to either the reproduction of the music data or the response to the incoming call according to the user's request.
