  Further, in the mobile phone system of the second form, when the mobile phone 2A on the calling side registers a message, image / song data, etc. for the mobile phone 2B in the content server 1 and designates the transmission date and time, At the designated date and time, the contents server 1 performs a telephone message service for sending a mail, making a call, etc. to the mobile phone 2B, and delivering the registered message, image / music data, and the like.

<< First Embodiment >>
The first embodiment relates to a mobile phone system in which the content server 1 provides a call transfer service. When the owner of the mobile phone 2A attempts to make a call to the mobile phone 2B using the call transfer service, the owner of the mobile phone 2A first makes a call to the content server 1. Then, after setting the additional sound to be synthesized for the content server 1, when the telephone number of the mobile phone 2B that is the other party of the call is input, the content server 1 calls the mobile phone 2B and passes through the content server 1. Thus, the mobile phones 2A and 2B can talk. Since all the call voices of the mobile phones 2A and 2B pass through the content server 1, the content server 1 generates additional sound at this time, and synthesizes and transfers the additional sound to the call voice.

  The additional sound includes a background sound that is continuously flowing in the background during a call and an effect sound that is generated once. Examples of background sounds include BGM (background music), environmental sounds such as station noise and natural sounds, and examples of sound effects include good hands and natural sounds. Here, BGM that is automatically played by music data such as MIDI is used as the background sound and the sound shown in FIG. 2 is used as the effect sound, but the present invention is not limited to this.

  The content server 1 stores a plurality of BGMs, and the holder of the mobile phone 2A can select a desired BGM before starting a call. This selection can be performed, for example, by operating a numeric keypad (including the * key and # key; the same applies hereinafter) of the mobile phone 2A to transmit a DTMF signal. This BGM is played in the background of the call voice during a call between the mobile phones 2A and 2B.

  The effect sound is generated in response to the numeric keypad operation of the owner of the mobile phone 2A and the call voice (predetermined keyword) of the owner (caller) of the mobile phones 2A and 2B. That is, when the holder of the mobile phone 2A operates the numeric keypad during a call and transmits a DTMF signal, the content server 1 generates a sound effect corresponding to the numeric keypad correspondingly. Further, when the owner of the mobile phone 2A or the owner of the mobile phone 2B speaks a predetermined keyword in the call, the content server 1 recognizes this and generates the corresponding sound corresponding to this keyword. To do.

  The content server 1 stores a plurality of types of effect sound sets. The effect sound set is a set of effect sounds corresponding to numeric keys 1, 2,..., 9, 0, for example, and a plurality of sets are stored. Also, a plurality of effect sounds corresponding to a predetermined keyword are stored as one set of one or more keywords and one or more effect sounds corresponding thereto.

  FIG. 2 is a diagram showing an example of the effect sound set corresponding to the numeric keypad. FIG. 4A is an example of a set in which natural sounds are combined in association with numeric keys 1 to 7. For example, when the owner of the mobile phone 2A presses numeric key 1 during a call, content server 1 Generates wind sound and synthesizes it with call voice. FIG. 4B is a set in which Kansai dialect voices (speaking words) are combined in association with numeric keys 1 to 9, for example, the owner of the cellular phone 2A presses the numeric keypad 1 during a call. Then, the content server 1 generates the word “Why is it?” And synthesizes it with the call voice. FIG. 6C shows a set in which voices in a specific TV program are combined in association with numeric keys 1 to 9, for example, when the owner of the mobile phone 2A presses numeric key 1 during a call, The server 1 generates the word “It's 8 o'clock” and synthesizes it with the call voice.

  In this embodiment, the effect sound set is assigned only to the numeric keypad operation of the mobile phone 2A. However, the effect sound set may be associated with the numeric keypad operation of the mobile phone 2B.

  In addition, as a sound effect set corresponding to a predetermined keyword, for example, the “Thank you” sound effect is associated with the keyword “Thank you”, or the “this is” sound effect is associated with “I'm sorry”. It would be nice to have a sound effect set. The effect sound set associated with the call voice from the mobile phone 2A and the effect sound set associated with the call sound from the mobile phone 2B may be set separately or the same. Moreover, you may set only to either one.

  The owner of the mobile phone 2A selects a desired sound effect set before starting a call, and assigns it to the numeric keypad of his / her mobile phone 2A, his own call voice, and the other party's call voice. This selection can be performed, for example, by operating a numeric keypad of the mobile phone 2A and transmitting a DTMF signal.

  The owner of the mobile phone 2A selects a desired BGM and sound effect set, and then inputs the phone number of the mobile phone 2B that is the other party, and connects to the mobile phone 2B. Then, when the holder of the mobile phone 2A operates the numeric keypad of the mobile phone 2A, or the holder of the mobile phones 2A, 2B speaks the keyword set in the selected sound effect set, it responds to it. The effect sound is generated by the content server 1, synthesized with the call sound, and transmitted to the mobile phones 2A and 2B.

  FIG. 3 is a block diagram of the content server 1 that implements the above functions. The content server 1 includes a control unit 10, a communication processing unit 11, a storage unit 12, and an audio signal processing unit 13. The communication processing unit 11 processes a call with the mobile phone 2 via the mobile phone network 3. The storage unit 12 includes a storage such as a hard disk, and stores a plurality of BGM song data, a sound effect set, and the like. The control unit 10 controls the operations of the communication processing unit 11 and the audio signal processing unit 13, and sets the BGM song data and the effect audio set stored in the storage unit 12 in the audio signal processing unit 13.

  The audio signal processing unit 13 is composed of one or a plurality of DSPs and includes the following functional blocks for executing the call transfer service.

  The DTMF signal detection unit 17 is a detection unit that receives a call voice signal transmitted from the mobile phone 2A on the transmission side from the communication processing unit 11 and detects a DTMF signal from the voice signal. The keyword A detection unit 18 is a detection unit that inputs a call voice signal transmitted from the mobile phone 2A on the caller side from the communication processing unit 11 and detects a predetermined keyword from the voice signal. The keyword B detection unit 19 is a detection unit that inputs a call voice signal transmitted from the mobile phone 2B on the receiving side from the communication processing unit 11 and detects a predetermined keyword from the voice signal.

  When the numeric keypad is operated on the cellular phone 2A, a DTMF signal (dual tone multi-frequency signal) having a frequency corresponding to the key is transmitted to the content server 1. The DTMF signal detection unit 17 is transmitted from the cellular phone 2A. Based on the sent DTMF signal, the key operated in the mobile phone 2A is detected. For this reason, it is based on a combination of a very narrow-band bandpass filter that passes only seven frequencies constituting the DTMF signal, a level detector that detects the level of the signal that has passed through each filter, and a frequency at which a high level is detected. In addition, a key indexing unit for indexing keys operated on the mobile phone 2A is provided. As a result, the determined key number is sent to the subsequent effect sound generating unit 22 during a call, and before the start of the call, that is, during the selection of BGM, the selection of the effect sound set, and the input of the destination phone number Is sent to the control unit 10 via the interface.

  The frequency of the DTMF signal detected by the DTMF signal detector 17 is also sent to the filter 20. The filter 20 is a filter for removing the DTMF signal included in the call voice sent from the mobile phone 2A, and is composed of a band cut-off filter of the seven types of frequencies having an extremely high Q. . In order not to impair the sound quality of the call voice, only when the DTMF signal detection unit 17 detects a DTMF signal, a band cutoff filter corresponding to the frequency of the DTMF signal is made to function (inserted into the signal line).

  Further, the keyword A detection unit 18 and the keyword B detection unit 19 include a speech recognition unit using a probabilistic model such as HMM (Hidden Markov Model), for example, and an effective speech set corresponding to a predetermined keyword is stored in the mobile phone 2A. HMM for recognizing the predetermined keyword is set from the control unit 10 via the interface 16. The HMM is stored in the storage unit 12 together with the effect sound set having the keyword. When the keyword A detection unit 18 detects a predetermined keyword (recognized by the set HMM), a signal indicating that the keyword has been detected is sent to the effect sound generation unit 23. When the keyword B detection unit 19 detects a predetermined keyword (recognized by the set HMM), a signal indicating that the keyword has been detected is sent to the effect sound generation unit 24. Note that the speech recognition method is not limited to the probability model method such as HMM.

  In each of the sound effect generating units 22, 23, and 24, a sound effect set (effect sound data) selected by the owner of the mobile phone 2A is set. This effect sound set is transferred from the control unit 10 via the interface 16.

  When a signal indicating that a predetermined key number has been detected is input from the DTMF signal detection unit 17, the effect sound generation unit 22 generates a corresponding effect sound and outputs the sound signal to the mixer 25. Further, when a signal indicating that a predetermined keyword is detected is input from the keyword A detection unit 18 and the keyword B detection unit 19, respectively, the effect sound generation units 23 and 24 generate corresponding effect sounds, and The audio signal is output to the mixer 25.

  The music performance unit 21 includes a sequence unit and a musical sound waveform synthesis unit, and plays the BGM music data transferred from the control unit 10 via the interface 16. This song data is selected by the owner of the mobile phone 2A and is transferred from the storage means 12 before the call is started. When a call start trigger is sent from the control unit 10, the automatic performance based on the BGM song data is started. The music data for BGM has a finite time, but when the call is continued, the music data is repeatedly played. BGM that is a performance sound generated by this performance is input to the mixer 25.

  The mixer 25 mixes the BGM and the effect sound and inputs them to the subsequent mixers 26 and 27.

  The mixer 26 mixes the call voice signal (DTMF signal has been removed by the filter 20) sent from the mobile phone 2 </ b> A, the BGM, and the effect voice and inputs them to the communication processing unit 11. The communication processing unit 11 transfers this audio signal to the mobile phone 2B. On the other hand, the mixer 27 mixes the call voice signal sent from the mobile phone 2 </ b> B, the BGM, and the effect voice and inputs them to the communication processing unit 11. The communication processing unit 11 transfers this audio signal to the mobile phone 2A.

  The above function of the audio signal processing unit 13 enables a call transfer service in which BGM and effect sound are combined with call voices of the mobile phones 2A and 2B.

  FIG. 4 is a flowchart showing the operation of the control unit 10 of the content server 1. This operation shows an operation when receiving a call from the mobile phone 2A and performing a call transfer service with the mobile phone 2B. When there is an incoming call from the mobile phone 2A (s1), in the content server 1, the communication processing unit 11 hooks off in response to this, and the control unit 10 responds to this with a synthesized voice (s2).

  In response to this response, the owner of the mobile phone 2A selects BGM, three types of effect sound sets, and the like for the content server 1. This selection is performed by operating a numeric keypad (including * key and # key), that is, by a DTMF signal. Note that the three types of effect sound sets are an effect sound set generated in response to a numeric keypad operation of the mobile phone 2A, an effect sound set generated in accordance with a predetermined keyword input from the mobile phone 2A, and a mobile phone that is a call partner. There are three types of effect voice sets that are generated according to a predetermined keyword input from the telephone 2B. The owner of the mobile phone 2A can select a desired one of these three types of effect voice sets and BGM. All can be selected. The effect sound set generated according to the predetermined keyword input from the mobile phone 2A and the effect sound set generated according to the predetermined keyword input from the mobile phone 2B are separate sets. May be the same set.

  When the DTMF signal for selection is sent in the content server 1, the DTMF signal detection unit 17 detects this and inputs the operation information of the corresponding numeric keypad to the control unit 10 via the interface 16. The control unit 10 reads out the BGM and / or effect sound set selected by the numeric keypad operation from the storage unit 12 and sets the BGM and / or effect sound set in the corresponding music performance unit 21 and / or effect sound generation units 22 to 24 (s4).

  After that, since the owner of the mobile phone 2A inputs the telephone number of the mobile phone 2B that is the other party of the call (s5), the mobile phone 2B is called via the mobile phone network 3 and the mobile phone 2B is A call is made (s6). On the other hand, when the cellular phone 2B responds (s7), the voice signal processing unit 13 is instructed to generate a BGM performance, a DTMF signal, and an effect voice corresponding to a predetermined keyword, and the call voice is synthesized and transferred. Start (s8).

  While the call between the mobile phone 2A and the mobile phone 2B is continued, the call transfer of the call voice is continuously executed, and when either one hangs up, the call transfer of the call voice is terminated, Also disconnect the phone with the other.

≪Second form≫
Next, a mobile phone system that performs a telephone message service according to the second embodiment will be described. In the telephone message service, as described above, the mobile phone 2A on the caller side registers the message contents such as messages, image / music data, etc. to the mobile phone 2B and the transmission date and time in the content server 1 in advance and is designated. This is a service in which the content server 1 sends the content to the mobile phone 2B by e-mail or phone call instead of the mobile phone 2A when the transmission date and time is reached.

  In order to realize this service, the content server 1 includes a control unit 30, a communication processing unit 31, a message content storage unit 32, an image database 33, and a song database 34 as shown in FIG. The message content storage unit 32 is a storage that stores the greeting content created by the owner of the mobile phone 2A until the transmission date and time. The image database 33 and the song database 34 are databases in which images and song data attached to message contents are registered.

  When the owner of the mobile phone 2A gives message content to the mobile phone 2B (owner), the owner of the mobile phone 2A calls the content server 1 and sends a voice message via the mobile phone 2A. While recording in the content server 1, a standby image, a background image during a call, an incoming melody (ringtone) at the time of an incoming call, and a background music (BGM) during a call are selected from the image database 33 and the song database 34. Then, when the owner of the mobile phone 2A inputs the transmission date and time of this message and the telephone number and mail address of the mobile phone 2B that is the destination, the content server 1 selects the audio data, image and song data selection information, and the telephone number. The mail address is stored in the message content storage unit 32 until the transmission date and time arrives.

  The control unit 30 constantly monitors the transmission date and time of all the message contents stored in the message content storage unit 32. If there is a transmission date and time, the control unit 30 waits from the image database 33 based on the selection information. The image data of the image and the background image during the call are read out, and the ringtone and BGM song data are read out from the song database 34 and attached to a mail to be transmitted to the mobile phone 2B.

  In this embodiment, image data and song data are selected from the database, but the owner of the mobile phone 2A may upload image data and song data from the mobile phone 2A. In this case, the message content storage unit 32 stores the image data and song data instead of the selection information.

  The mobile phone 2B receives this mail and sets so that the attached documents are automatically reproduced. That is, the image data of the standby image is set as a so-called standby image so that it is always displayed during standby, and the image data of the background image is set to be displayed during a call. The ringtone song data is set to be played when a call is received, and the BGM song data is set to be played during a call.

  The image data and song data setting function may be incorporated as a basic function of the mobile phone 2B. However, the contents server 1 attaches a JAVA (registered trademark) program together with the image data and song data to the above-mentioned mail, The telephone 2B may automatically execute the JAVA (registered trademark) program so that the image data and song data setting processing is performed.

  After sending the e-mail, the content server 1 waits for a certain period of time (waits for the time that the setting of the automatic playback is completed in the mobile phone 2B), and then waits for a call to the mobile phone 2B. Multiply. On the mobile phone 2B, a ringtone is played when this call is made, and a standby image is displayed on the screen (although the caller's telephone number is displayed on the ringtone). When the owner responds to this call, the song to be played is changed to BGM, and the screen displayed on the screen is changed to the background image. This response (hook off) is transmitted to the content server 1 via the cellular phone network 3.

  In response to this response, the content server 1 reads and plays the greeting message recorded by the owner of the mobile phone 2A stored in the message content storage unit 32 and transmits it to the mobile phone 2B as a call voice. . Thereby, the holder of the mobile phone 2B can listen to the greeting message while watching the background video in an environment where BGM flows.

  The BGM may be output from a ringtone speaker or may be output from a speaker for receiving a call. In addition, when the owner of the mobile phone 2B wants to listen to the greeting message while watching the background video, the user should respond after wearing a hands-free device such as an earphone.

  FIG. 6 shows a block diagram of the mobile phone 2. The mobile phone 2 automatically sets the image data and song data received as an e-mail attachment as described above to the standby image, background image, ringtone, and BGM through automatic processing without the owner's setting operation. It has a function.

  A system CPU 40 that controls the overall operation of the mobile phone includes a system RAM 41, a system ROM 42, a communication unit 43, an audio processing unit (coder / decoder) 44, a music performance unit 45, a variable gain amplifier 48, a variable gain, via a bus 59. An amplifier 51 (51a, 51b), an input unit 54, and a display unit 55 are connected. The system CPU 40 executes a telephone function program for realizing the function of the mobile phone and also executes a JAVA (registered trademark) program downloaded from the content server 1 or the like. The system RAM 41 stores ringtones, BGM song data, standby images, and background image image data received from the content server 1.

  The communication unit 43 receives a radio wave sent from the mobile phone network 3 by an antenna, demodulates a signal superimposed on the radio wave, modulates a signal to be transmitted to the mobile phone network 3, and transmits it to the antenna. Supply. The reception signal demodulated by the communication unit 43 is decoded by a voice processing unit (coder / decoder) 44, amplified by a variable gain amplifier 51 a, and then emitted from a reception speaker 53 via a mixer 52. The transmission signal input from the microphone 58 is compressed and encoded by the voice processing unit 44 and then input to the communication unit 43 as a transmission signal.

  The music playing unit 45 plays music based on the ringtone and BGM song data stored in the system RAM 41. When an incoming call is received, a ringtone is automatically played, and a musical tone signal formed thereby is emitted from the calling speaker 50 via the variable gain amplifier 48. Further, during a call, the BGM is automatically played, and the musical sound signal formed thereby is emitted from the receiving speaker 53 via the variable gain amplifier 51b and the mixer 52. The BGM tone signal may be emitted from the calling speaker 50 via the variable gain amplifier 48 in the same manner as the ringtone tone signal.

  The input unit 54 includes a button switch such as a numeric keypad, and the system CPU 40 forms a DTMF signal corresponding to the operation of the numeric keypad in the music performance unit 45, and the cellular phone network via the voice processing unit 44 and the communication unit 43. 3 to send. The display unit 55 is a color liquid crystal matrix display, and displays a standby screen, a background image during a call, and the like.

  FIG. 7 is a flowchart showing a processing procedure of the mobile phone system that executes the telephone message service according to the second embodiment.

  First, a call is made from the mobile phone 2A to the content server 1 to register the message content (s10). Registration includes the following processes: A voice message (greeting message) is recorded, and a standby image and a background image are selected from the image data stored in the image database 33 or uploaded from the mobile phone 2A. Also, the ringtone and BGM song data are selected from the song data stored in the song database 34 or uploaded from the mobile phone 2A. Along with the content, the telephone number, mail address, and transmission date and time of the content are transmitted.

  The content server 1 stores the message content (including the telephone number, mail address, and transmission date / time) received from the mobile phone 2A in the message content storage unit 32 (s11). Then, nothing is performed on this content until the transmission date and time of this message content is reached (s12).

  When the transmission date and time of this greeting content arrives (s12), first, an e-mail attached with standby image, background image image data, ringtone and BGM song data is transmitted to the destination mobile phone 2B (s13). . A JAVA (registered trademark) program for automatically setting the image and song data may be attached to the mail.

  The mobile phone 2B receives this mail (s14), sets automatic display of the standby image and the background image (s15), and sets ringtone and BGM automatic performance (s16). Thereby, at this time, the standby image is displayed on the display unit 55 of the mobile phone 2B.

  The content server 1 waits for a time that the mobile phone 2B executes the setting process (s17), and then makes a call to the mobile phone 2B (s18). With this call, the ringtone set in s16 is played as a ringing tone on the mobile phone 2B (s19). When the owner turns on the hook-off button and responds thereto (s20), the response signal is transmitted to the content server 1. On the other hand, in response to this response, the mobile phone 2B starts playing BGM instead of ringtones (s21), and the display unit 55 displays a background image instead of the standby image (s22).

  In response to the response from the mobile phone 2B, the content server 1 transmits the voice message stored in the message content storage unit 32 as a call voice (s23). This voice message is received by the cellular phone 2B and emitted from the receiving speaker 53, and the owner can hear this message (s24).

  In the second mode, the content server 1 sends image data or song data to the mobile phone 2B by e-mail first, and then makes a phone call to convey a voice message. It may be possible to make a phone call first to notify that there is a greeting mail and then send the greeting mail.

  FIG. 8 shows a flowchart when the telephone message service is performed in such a procedure. When the owner of the mobile phone 2A as the sender accesses the content server 1 (s30), the content server 1 authenticates the user (s31). If the authentication is OK, the greeting server creates a greeting mail on the content server 1 And accepts the setting of the transmission destination and the transmission date and time (s32). The greeting mail (including the transmission destination and the transmission date / time) created in this step is stored in the message content storage unit 32.

  When the transmission date and time arrives, the content server 1 calls the destination (mobile phone 2B) (s33), and when the receiver (owner of the mobile phone 2B) responds (s34), the mobile phone 2A that is the sender A voice message or the like recorded by the owner is transmitted (s35). This voice message is composed of a greeting (message) and a content to send a greeting mail.
