BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

 FIG. 1 is a block diagram showing a configuration of a mobile terminal device 1 according to an embodiment of the present invention. In the present embodiment, a mobile terminal device 1 will be described as a telephone device. The mobile terminal device 1 receives content data such as voice data, character data, and image data from a communication network constructed by a plurality of telephone devices and a plurality of base stations via radio waves and communicates the content data. Send to the network. The mobile terminal device 1 performs telephone communication with other telephone devices by transmitting and receiving voice data.

The mobile terminal device 1 includes a communication control unit 2, a microphone 3, a speech encoding unit 4, a speech power 5, a speech decoding unit 6, a main control unit 7, a display unit 8, an operation button unit 9 A memory 10, an antenna 11, a timer unit 16, and an imaging unit 17. The main control unit 7 performs arithmetic processing by reading and executing a program stored in the memory 10, and controls each unit constituting the mobile terminal device 1. The main control unit 7 is realized by, for example, a central processing unit (abbreviated as CPU). The main control unit 7 corresponds to packet processing means.

 The microphone 3 converts the sound into an electric signal represented by an analog value and supplies the electric signal to the sound coding unit 4. The audio encoding unit 4 encodes the electrical signal given from the microphone 3 and generates audio data represented by a digital value. More specifically, the voice encoding unit 4 samples the electrical signal supplied from the microphone 3 at a predetermined time interval and converts it into an electrical signal represented by a digital value. In the present embodiment, the audio encoding unit 4 performs encoding based on a PCM (Pulse Code Modulation) method to generate audio data. The voice code key unit 4 gives the generated voice data to the main control unit 7. The microphone 3 and the voice code input unit 4 correspond to voice data generation means.

 The voice decoding unit 6 decodes the voice data given from the main control unit 7 and converts it into an electrical signal represented by an analog value. The voice decoding unit 6 gives the converted electric signal to the speaker 5. The speaker 5 outputs an electrical signal that can be given from the speech decoding unit 6 as speech. The speaker 5 and the voice decoding unit 6 correspond to output means.

 The communication control unit 2 controls communication such as establishment and termination of communication with the telephone devices constituting the communication network, and transmission / reception of content data via the antenna 11. The communication control unit 2 corresponds to transmission / reception means. Based on the control of the main control unit 7, the display unit 8 visually displays instructions to the user of the mobile terminal device 1 and image information. The display unit 8 is realized by, for example, a liquid crystal display (abbreviated as LCD). The antenna 11 captures radio waves, converts them into electric signals, and gives the converted electric signals to the communication control unit 2. The antenna 11 converts the electric signal given from the communication control unit 2 into a radio wave and radiates it.

The operation button unit 9 corresponds to an input means, and is realized including a numeric keypad, a call start button, a call end button, and the like. When the user of the mobile terminal device 1 operates a numeric keypad or the like based on the image information displayed on the display unit 8, a command corresponding to this operation is given to the main control unit 7.

The imaging unit 17 irradiates the CCD with light of subject power through a lens, converts the irradiated light into an electrical signal, and generates image data. The imaging unit 17 gives the generated image data to the main control unit 7.

 FIG. 2 is a diagram for explaining the relationship between the transmission packet group 12a generated by the main control unit 7 and the thinned transmission packet group 12b.

 The main control unit 7 adds a header to the audio data given from the audio code key unit 4 and packetizes the audio data at predetermined time intervals. In the present embodiment, the main control unit 7 generates voice packets in order of time series from voice data based on RTP (Real-time Transport Protocol). Hereinafter, a packet generated by the main control unit 7 and to be transmitted by the communication control unit 2 is referred to as a transmission packet, and a packet received by the communication control unit 2 is referred to as a reception packet. The header of the transmission packet includes the IP address of the communication partner's terminal. FIG. 2 shows a transmission packet group 12a composed of five transmission packets generated based on voice data. In Fig. 2, the numbers 1 to 5 are assigned in chronological order generated for five transmission packets.

The main control unit 7 gives the generated transmission packet to the communication control unit 2. The main control unit 7 outputs a predetermined ratio of transmission packets generated among the plurality of generated transmission packets and gives the communication control unit 2 when a predetermined condition described later is met. The predetermined ratio is a value obtained by dividing the number of output transmission packets by the number of all generated transmission packets. The main control unit 7 thins out the transmission packets by discarding the transmission packets that are obtained by subtracting the predetermined ratio from the numerical value 1 of the generated transmission packets, and performs communication control on the remaining transmission packets excluding the thinned transmission packets. Give to part 2. Hereinafter, the value obtained by multiplying the value 1 by subtracting the predetermined percentage from 100 is called the thinning rate. In Fig. 2, every other generated transmission packet is discarded in chronological order, and the transmission packet group 12b is shown. In this case, the predetermined ratio is 1/2 and the thinning rate is 50%.

 Since the communication control unit 2 transmits the transmission packet given from the main control unit 7 as a radio wave via the antenna 11, the thinned transmission packet is transmitted to the communication partner. When the communication partner's terminal receives the decoded packet after it has been decimated and decodes it, the voice data is lost, resulting in choppy voice. When the communication partner hears this, it feels that the communication status of the communication partner's terminal is bad.

 FIG. 3 is a flowchart showing communication processing of the mobile terminal device 1. When there is an incoming call from the caller terminal and the connection establishment process is performed and a ringing tone indicating that the incoming call is received from the speaker 5 is sounded, the process proceeds from step aO to step a1.

 In step al, the main control unit 7 determines whether or not the call start button of the operation button unit 9 has been pressed. If it is determined that the button has been pressed, the process proceeds to step a2. In step al, when the main control unit 7 determines that the call start button of the operation button unit 9 is depressed, the main control unit 7 repeatedly determines whether or not the force is depressed until the call start button is depressed. .

 In step a2, the main control unit 7 initializes information related to the talk time and thinning processing stored in the memory 10. Specifically, the call time is set to zero seconds. In this embodiment, the discarding rate of discarded transmission packets is set to 50%. When initialization is complete, go to step a3. In step a3, the main control unit 7 performs communication processing, starts a call loop, and proceeds to step a4.

 In step a4, the main control unit 7 generates a transmission packet based on the voice input to the microphone 3. First, the microphone 3 converts the input voice into an electrical signal represented by an analog value and gives it to the voice encoding unit 4. Next, the speech encoding unit 4 encodes an electrical signal represented by an analog value given from the microphone 3 to generate speech data represented by a digital value. Next, the main control unit 7 adds a header to the audio data and generates a transmission packet. Then go to step a5.

In step a5, the main control unit 7 performs a thinning determination process described later. When the main control unit 7 performs the interval determination process, the interval I flag stored in the memory 10 is set to either ON (ON) force OFF (OFF). When the decimation flag power is ON, this indicates that the transmission packet is decimation, and when the decimation flag is OFF, this indicates that the transmission packet is not decimation. . In this embodiment, the thinning rate is 50%, and even-numbered transmission packets generated in chronological order are discarded. Therefore, if the transmission packet generated in step a4 is an even-numbered transmission packet, the thinning flag is set. Is turned ON, and if it is an odd-numbered transmission packet, the flag for the crossbow I is turned OFF. Then go to step a6.

 In step a6, the main control unit 7 determines whether or not the timing power to discard the transmission packet is based on the thinning flag. Specifically, if the thinning flag is OFF, the main control unit 7 determines that it is not time to discard the transmission packet, and proceeds to step a7. If the thinning flag is ON, the main control unit 7 determines that it is time to discard the transmission packet, and proceeds to step a8. In step a7, since it is not the thinning-out timing, the main control unit 7 sends the transmission packet generated in step a4 to the communication control unit 2 so that the transmission packet is transmitted from the antenna 11, and the process proceeds to step a9. In step a8, because it is the thinning-out timing, the main control unit 7 discards the transmission packet generated in step a4 without giving it to the communication control unit 2, and proceeds to step a9.

 In step a9, the speaker 5 outputs sound based on the received received packet. First, the main control unit 7 removes a header from the received packet, generates voice data, and gives the generated voice data to the voice decoding unit 6. Next, the audio decoding unit 6 decodes the audio data, converts it into an electric signal represented by an analog value, and gives it to the speaker 5. Next, the speaker 5 outputs the given electric signal as sound. Then go to step alO. The main control unit 7 repeats the call loop from step a3 to step alO until the call end button is pressed. When the call end button is pressed during the call loop, the main control unit 7 exits the call loop, performs a process for ending the call, moves to step all, and ends the communication process.

FIG. 4 is a flowchart showing the thinning determination process of step a5 shown in FIG. When the decimation determination process starts, the process moves from step bO to step bl. In step bl, the main control unit 7 determines whether or not the generated transmission packet is a transmission packet that is generated evenly after starting a call. When determining that the transmission packet is an even-numbered transmission packet, the main control unit 7 proceeds to step b2, and when determining that it is not an even-numbered transmission packet, that is, an odd-numbered transmission packet, the main control unit 7 proceeds to step b3. In this embodiment, FIG. Since the even-numbered generated transmission packet is discarded as shown in FIG. 4, in step b2, the main control unit 7 sets the thinning flag to ON and proceeds to step b4. In this embodiment, since the odd-numbered transmission packet is transmitted without being discarded, in step b3, the thinning flag is set to OFF and the process proceeds to step b4. In step b4, the thinning judgment process is terminated.

 According to the mobile terminal device 1 described above, the mobile terminal device 1 intermittently transmits a part of all the generated transmission packets. Other telephone devices that have received the transmission packet transmitted from the mobile terminal device 1 lose some of the transmission packets, and therefore, the voice before being converted by the microphone 3 and the voice encoding unit 4 is received. The sound cannot be reproduced and the sound is interrupted.

 For example, if the mobile terminal device 1 is located far away from the base station and cannot transmit the transmission packet to the base station, and if the packet is congested! In a bad situation, the audio is interrupted. Thus, the mobile terminal device 1 can create the same situation as the situation where the communication state is bad by intermittently transmitting a part of all the generated transmission packets. As a result, the user of the telephone device can end the call while making the other party think that the communication state is bad. If communication is terminated with the interrupted voice output from the other party's telephone device, the communication partner does not think that the communication has been intentionally terminated, and the communication is caused by the deterioration of the communication state. You are more likely to think it is finished. If you want to end communication during communication, unilaterally ending communication may harm the other party's feelings, so it may be difficult to end communication, but if you intentionally end communication, Since the communication can be terminated unexpectedly, the user can terminate the communication with peace of mind. Especially in the case of nuisance calls, there is a possibility that nuisance calls may be made persistently if the other party's feelings are harmed. If possible, it is likely that you will not be able to communicate.

In addition, the mobile terminal device 1 of the present invention can intermittently transmit a part of transmission packets generated by using a hardware configuration necessary for telephone communication simply by changing the software. Noise generation circuit and noise insertion circuit, etc. as in the conventional technology There is no need to add the configuration. As a result, it is possible to create the same situation as the situation where the communication state is bad without complicating the configuration of the apparatus.

 In the mobile terminal device 1 of the present embodiment, the thinning rate is set to 50% and the even-numbered transmission bucket is discarded. However, the thinning rate is not limited to 50%.

FIG. 5 is a diagram for explaining the relationship among the transmission packet group 12a generated by the main control unit 7 when the thinning rate is 75%, the thinned transmission packet group 12b, and the further thinned transmission packet group 12c. FIG. In step bl, the main control unit 7 determines which of step b2 and step b3 is to be performed according to the thinning rate. When the thinning rate is 75%, the main control unit 7 discards the 4 X n—second, 4 X n—first and 4 X n th generated transmission packets. Here, the symbol “n” represents a natural number. Specifically, in step bl shown in FIG. 4, the main control unit 7 determines that the generated transmission packet starts the call and has the power 4 X n—second, 4 X n—first or 4 X n th. It is determined whether or not the transmission packet is generated in the next step. If the main control unit 7 determines that the transmission packet is 4 X n—second, 4 X n—first or 4 X nth, it proceeds to step b 2 and 4 X n—second, 4 If it is determined that the transmission packet is not Xn—first or 4Xn, that is, 4Xn—third transmission packet, the process proceeds to step b3. By changing the decimation rate in this way, it is possible to decimate transmission packets further than the decimation rate of 50% as shown in FIG. If the decimation rate is increased, the audio output from the other party's terminal will be more discontinuous, so that the other party feels that the communication status of the mobile terminal device 1 is worse. Can do. The mobile terminal device 1 according to another embodiment of the present invention changes the predetermined ratio to random based on random numbers. That is, the thinning rate is randomly changed based on the random number. Since the portable terminal device 1 of this embodiment is different from the above-described portable terminal device 1 only in the thinning-out determination process, description of overlapping processing is omitted and only the thinning-out determination process is described. It is a flowchart showing this determination processing. When the thinning judgment process starts, the step cO force also shifts to step cl. In step cl, the main control unit 7 determines whether or not the timing power for changing the thinning rate P is correct. Specifically, the main control unit 7 changes the thinning rate P when a predetermined time has elapsed from the time when the previous thinning rate P was changed. The timing is determined to proceed to step c2. The predetermined time is measured by the timer unit 16. The predetermined time is set to a time when the situation in which the communication control unit 2 can transmit and receive radio waves changes in a situation where the mobile terminal device 1 is used, and is selected from 3 seconds to 5 seconds, for example.

 In step c2, the main control unit 7 generates a random number not less than 0 and not more than 100, sets the generated random number as the thinning rate P, and proceeds to step c3. In step cl, if the predetermined time has not elapsed since the time when the main control unit 7 changed the thinning rate P last time, it is determined that it is not the timing for changing the thinning rate P, and the process proceeds to step c3. . In step c3, the main control unit 7 generates a random number R of 1 or more and 100 or less, and proceeds to step c4.

 In step c4, the main control unit 7 determines whether or not it is greater than or equal to the random number R generated in the thinning rate P force step c3 set in step c2. If the thinning rate P is greater than or equal to the random number R, the process proceeds to step c5, and if the thinning rate P is less than the random number R, the process proceeds to step c6. In step c5, the main control unit 7 sets the thinning flag to ON, and proceeds to step c7. In step c6, the thinning flag is set to OFF and the process proceeds to step c7. In step c7, the thinning determination process ends.

 As described above, since the thinning rate P changes with time, the frequency at which the audio output from the telephone device of the communication partner is interrupted changes randomly. Since the actual communication state changes with time, the frequency at which voice is interrupted also changes with time in actual communication. The mobile terminal device 1 can create a situation close to the actual communication state by randomly changing the frequency at which the voice output from other telephone device power is interrupted in the same manner as in actual communication. In particular, since the above-mentioned predetermined time is set to a time when the situation in which the communication control unit 2 can transmit and receive radio waves changes in the situation where the mobile terminal device 1 is used, the actual communication state may be deteriorated. It is possible to create a situation close to time change. As a result, the user of the telephone device can end the call while making the other party think that the communication state is poor.

In the portable terminal device 1 according to another embodiment of the present invention, the predetermined ratio decreases as time elapses. That is, the thinning rate increases as time elapses. Implementation Since the portable terminal device 1 of the embodiment is different from the above-described portable terminal device 1 only in the thinning determination process, the description of the overlapping process is omitted and only the thinning determination process is described. FIG. 7 is a flowchart showing the thinning determination process. When decimation determination processing starts, the process moves from step dO to step dl. In step dl, the main control unit 7 determines whether or not the timing force for changing the thinning rate P is satisfied. Specifically, when a predetermined time has elapsed since the time when the thinning rate P was changed last time, the main control unit 7 determines that the timing for changing the thinning rate P has been reached and proceeds to step d2. As described above, the predetermined time is set to about 3 to 5 seconds, which is set to a time when the situation in which the communication control unit 2 can transmit and receive radio waves changes in the situation where the mobile terminal device 1 is used.

 In step d2, the main control unit 7 sets a value obtained by adding a predetermined value to the thinning rate P as the thinning rate P, and proceeds to step d3. In step dl, when the predetermined time has passed since the time when the main controller 7 changed the previous thinning rate P! / ,! Judge and go to step d3. In step d3, the main control unit 7 generates a random number R of 1 or more and 100 or less, and proceeds to step d4. In step d4, the main control unit 7 determines whether or not the power is greater than or equal to the random number R generated in the thinning rate P force step d3 set in step d2. If the punctuation rate P is greater than or equal to the random number R, the process proceeds to step d5. If the decimation rate P is less than the random number R, the process proceeds to step d6. In step d5, the main control unit 7 sets the thinning flag to ON, and proceeds to step d7. In step d6, the thinning flag is set to OFF and the process proceeds to step d7. In step d7, the determination process of the space bow I ends.

As described above, since the thinning rate P increases with time, the frequency at which the voice output from the telephone device of the communication partner is interrupted increases with time. In actual communication, as the communication state deteriorates, the frequency of voice interruptions increases with time. The mobile terminal device 1 can create a situation close to a situation where the communication state is deteriorated by increasing the frequency at which the sound output from other telephone devices is interrupted over time. In particular, since the above-mentioned predetermined time is set to a time when the situation in which the communication control unit 2 can transmit and receive radio waves changes in the situation where the mobile terminal device 1 is used, the actual communication state may be deteriorated. To create a situation close to time it can. As a result, the user of the telephone device can end the call while making the other party think that the communication state is bad.

 The mobile terminal device 1 according to another embodiment of the present invention determines whether or not to permit the discard of the transmission packet based on the selection command input from the operation button unit 9. The mobile terminal device 1 sets the thinning operation state to the permitted state when a specific button of the operation button unit 9 is pressed by the user, and performs the thinning operation when a button different from the specific button is pressed. Set the state to the prohibited state. For example, if the numeric key “1” button is pressed and a selection command is input, the thinning operation state is set to the permitted state, and the numeric key “2” button is pressed and the selection command is input. Then, the thinning operation state is set to the prohibited state. When the thinning-out operation state is set to the permitted state, a packet discard mode in which a predetermined ratio of the transmission packets generated by the main control unit 7 is output to the communication control unit 2 is set. When the thinning-out operation state is set to the prohibition state, a full packet output mode in which all the plurality of transmission packets generated by the main control unit 7 are output to the communication control unit 2 is set.

 FIG. 8 is a flowchart showing a process in which the main control unit 7 sets the operation state of the interstitch. If the number key “1” or “2” button on the numeric keypad is pressed during a call loop and a selection command is input, an interrupt process occurs and the process goes from step eO to step el. In step el, the main control unit 7 determines whether or not the information indicating the operation permission state has been input. If it is determined that the information indicating the operation permission state has been input, the main control unit 7 proceeds to step e2 and permits the operation. If it is determined that the prohibition state is input, the process moves to step e3. Specifically, if it is determined that the numeric key “1” is depressed, the process proceeds to step e2, and if it is determined that the numeric key “2” is depressed, the process proceeds to step e3.

 In step e2, the main control unit 7 sets the thinning operation state to the permitted state, and proceeds to step e4. In step e3, the main control unit 7 sets the thinning operation state to the prohibited state, and proceeds to step e4. In step e4, the interrupt process is terminated.

As described above, when the main control unit 7 executes the process shown in the flowchart of FIG. 8, the thinning-out operation state is set to the permitted state force prohibited state based on the operation of the operation button unit 9 by the user. The FIG. 9 is a flowchart showing communication processing of the mobile terminal device 1. When there is an incoming call from the caller terminal and the connection establishment process is performed and a ringing tone indicating that the incoming call is received from the speaker 5 is sounded, the process proceeds from step fO to step fl.

 In step fl, the main control unit 7 determines whether or not the call start button of the operation button unit 9 has been pressed. If it is determined that the button has been pressed, the process proceeds to step f2. In step fl, when the main control unit 7 determines that the call start button of the operation button unit 9 is depressed, it repeats the determination of whether or not the force is depressed until the call start button is depressed. .

 In step f2, the main control unit 7 initializes information related to the talk time and thinning processing stored in the memory 10. Specifically, the call time is set to zero seconds. In this embodiment, the thinning rate is set to 50%. In addition, the thinning-out operation is set to either the permitted state or the prohibited state based on the initial setting stored in the memory 10. When initialization is completed, the process proceeds to step f3. In step f3, the main control unit 7 performs communication processing, starts a call loop, and proceeds to step f4.

 In step f4, the main control unit 7 generates a transmission packet based on the voice input to the microphone 3. First, the microphone 3 converts the input voice into an electrical signal represented by an analog value and gives it to the voice encoding unit 4. Next, the speech encoding unit 4 encodes an electrical signal represented by an analog value given from the microphone 3 to generate speech data represented by a digital value. Next, the main control unit 7 adds a header to the audio data and generates a transmission packet. Next, the process proceeds to step f5.

In step f5, the main control unit 7 determines whether or not the thinning-out operation is permitted. If the number “1” or “2” button on the operation button section 9 has not been pressed down once the call loop has started, the thinning operation remains at the initial setting. When the process shown in the flowchart of FIG. 8 is performed after the call loop is started, the thinning-out operation is set based on the user's operation. When the main control unit 7 determines that the thinning-out operation is permitted, the main control unit 7 proceeds to step f6. In step f 6, the main control unit 7 performs the thinning determination process shown in the flowchart of FIG. 4, and proceeds to step f 7. In step f7, the main control unit 7 determines whether or not it has the timing power to discard the transmission packet based on the thinning flag. Specifically, the main control unit 7 determines that the transmission packet should be discarded when the thinning flag is OFF. Judge and go to step f8. If the thinning flag is ON, the main control unit 7 determines that it is time to discard the transmission packet, and proceeds to step f9. In step f5, if the main control unit 7 determines that the bowing operation is prohibited, the process proceeds to step f8.

 In step f8, the main control unit 7 gives the transmission packet generated in step f4 to the communication control unit 2 to transmit the transmission packet from the antenna 11, and proceeds to step f10. In step f9, the main control unit 7 discards the transmission packet generated in step f4 without giving it to the communication control unit 2, and proceeds to step flO.

 In step f10, the speaker 5 outputs sound based on the received packet received. First, the main control unit 7 generates audio data by removing the header from the received packet, and gives the generated audio data to the audio decoding unit 6. Next, the voice decoding unit 6 decodes the voice data, converts it into an electric signal represented by an analog value, and gives it to the speaker 5. Next, the speaker 5 outputs the given electrical signal as sound. Then go to step f11. The main control unit 7 repeats the call loop from step f3 to step f11 until the call end button is pressed. When the call end button is pressed during the call loop, the main control unit 7 exits the call loop, performs a process for ending the call, proceeds to step fl2, and ends the communication process.

 According to the mobile terminal device 1 of the present embodiment described above, a packet discard mode for outputting a predetermined ratio of transmission packets among a plurality of generated transmission packets, and all of the generated plurality of transmission packets are output. The full packet output mode is selected based on the selection command input from the operation button unit 9. As a result, it is selected whether to transmit a part of the transmission packet generated according to the operation of the operation button section 9 of the user intermittently or to transmit all the transmission packets, and the convenience for the user is selected. Will improve.

The mobile terminal device 1 according to another embodiment of the present invention is different in the process of determining the bow I during the step f6 of the mobile terminal device 1 that performs the flow chart processing of FIGS. The thinning rate P is increased in accordance with the operation of the operation button unit 9 by the user. Since the communication processing of the mobile terminal device 1 of the present embodiment is the same as the processing of the flowchart of FIG. 9 described above, description of overlapping processing is omitted. Figure 10 increases the thinning rate P! It is a flowchart showing the process to perform. The portable terminal device 1 increases the thinning rate P when a specific button of the operation button unit 9 is pressed by the user. In this embodiment, the thinning rate P increases when the numeric key “3” button is pressed. When the number “3” button on the numeric keypad is pressed, interrupt processing occurs and the process moves from step gO to step gl. In step gl, the main control unit 7 newly sets a value obtained by adding a predetermined value to the thinning rate P as the thinning rate P, and increases the thinning rate P. Next, the process proceeds to step g2, and the interrupt process is terminated.

 Since the main control unit 7 performs the processing shown in the flowchart of FIG. 10 every time the numeric key “3” is pressed, the thinning rate P increases every time the numeric key “3” is pressed. FIG. 11 is a flowchart showing the thinning determination process of step f6 in FIG. When the thinning judgment process starts, the process moves from step hO to step hi. In step hi, the main control unit 7 generates a random number R of 1 or more and 100 or less, and proceeds to step h2. In step h2, the main control unit 7 determines whether or not it is greater than or equal to the random number R generated in the thinning rate P force step h2. If the thinning rate P is greater than or equal to the random number R, the process proceeds to step h3, and if the thinning rate P is less than the random number R, the process proceeds to step h4. In step h3, the main control unit 7 sets the thinning flag to ON and proceeds to step h5. In step h4, the thinning flag is set to OFF and the process proceeds to step h5. In step h5, the thinning determination process is terminated.

 By performing the processing shown in the flowchart of FIG. 11, the inter-bow flag is set to either ON or OFF, and whether to discard the transmission packet can be set according to the thinning rate P. Monkey.

 According to the mobile terminal device 1 of the present embodiment described above, the proportion of transmission packets transmitted from the telephone device out of the transmission packets to be generated decreases according to the operation of the operation button unit 9 by the user. Therefore, the user can artificially deteriorate the communication state of the telephone device by operating the operation button unit 9, and can make the communication partner feel that the communication state is bad. If the user terminates the communication at this time, it is possible to make the communication partner think that the communication is terminated due to the bad communication state.

The mobile terminal device 1 according to another embodiment of the present invention is a flowchart of the above-described FIGS. In addition to the portable terminal device 1 that performs the above process, the thinning rate P is set according to the operation of the operation button unit 9 by the user. The communication processing of the mobile terminal device 1 of the present embodiment is the same as the processing of the flowchart of FIG.

Since it is the same as the process of the flowchart of 11, the description of the overlapping process is omitted. FIG. 12 is a flowchart showing a process of changing the thinning rate P. The portable terminal device 1 changes the thinning rate P when a specific button of the operation button unit 9 is pressed by the user. For example, based on the image information displayed on the display unit 8, when the user operates the operation button unit 9 and the thinning rate P is input, an interrupt process occurs, and the process proceeds from step jO to step jl. To do. In step jl, the main control unit 7 sets the thinning rate P to a value corresponding to the operation of the operation button unit 9. Next, the process proceeds to step j2, and the interrupt process is terminated.

 The main control unit 7 determines the thinning process shown in FIG. 11 based on the thinning rate P set by performing the process shown in the flowchart of FIG. As a result, the mobile terminal device 1 transmits the transmission packet group after the transmission packets are thinned out at the thinning rate P according to the operation of the operation button unit 9 by the user.

 According to the mobile terminal device 1 of the present embodiment described above, the ratio of the transmission packets transmitted from the mobile terminal device 1 among the generated transmission packets is set according to the operation of the operation button unit 9 by the user. Is done. Therefore, the user can set the communication state of the mobile terminal device 1 in a pseudo-free manner by operating the operation button unit 9, and the convenience for the user is improved.

 In the mobile terminal device 1 according to another embodiment of the present invention, the main control unit 7 outputs transmission packets to the communication control unit 2 except for a plurality of transmission packets that are continuous in time series. That is, the main control unit 7 discards a plurality of transmission packets that are continuous in time series. Since the mobile terminal device 1 of the present embodiment is different in the thinning determination process of the mobile terminal device 1 of each of the above-described embodiments and the communication process is the same, the description of the overlapping process is omitted and the thinning determination process is omitted. Only explained.

FIG. 13 is a flowchart showing the thinning determination process. When the thinning judgment process starts, the step kO force also shifts to step kl. In step kl, the main control unit 7 determines whether or not the timing power to thin out the transmission packet is sufficient. Specifically, the main control unit 7 Step c3 and step c4 shown are executed, and if the random number R is equal to or less than the thinning rate P, it is determined that the thinning timing is reached and the process proceeds to step k2. In step k2, the main control unit 7 initializes the continuous thinning counter. The initial value of this continuous thinning counter represents at least the number of transmission packets that should be discarded continuously. Next, the process proceeds to step k3. If the random number R is larger than the thinning rate P at step kl, it is determined that it is not the thinning timing, and the process proceeds to step k3.

 In step k3, the main control unit 7 determines whether or not the continuous thinning counter is greater than zero. If the continuous decimation counter is greater than 0, it is determined that the transmission packet should be discarded, and the process proceeds to step k4. In step k4, the main control unit 7 sets the thinning flag to ON and proceeds to step k5. In step k5, the main control unit 7 sets a value obtained by subtracting 1 from the continuous thinning counter as the continuous bow I counter, and proceeds to step k7.

 In step k3, when the main control unit 7 determines that the continuous thinning counter is not greater than 0, specifically, the continuous thinning counter is 0, it determines that the transmission packet should be transmitted without discarding, and step k6 Migrate to In step k6, the main control unit 7 sets the thinning flag to OFF and proceeds to step k7. In step k7, the thinning determination process ends.

 In step k2, once the continuous decimation counter is initialized, V is decremented in step k5, and the decimation counter is decremented to 0. Become. As a result, when transmission packets start to be discarded, at least the number of continuous transmission counters that are continuous in time-series order are discarded.

According to the mobile terminal device 1 of the present embodiment described above, the transmission packet after the transmission packets consecutive in time series are thinned out is transmitted to the telephone device of the communication partner. The telephone device of the communication partner that receives the transmitted packet may copy the data of the packet immediately before the missing packet in time series and output it as voice to complement the missing packet. In this way, the telephone device of the communication partner supplements the lost packet to prevent the voice from being heard intermittently. If it does not receive a continuous transmission packet in time series, the lost packet is not received. The sound is output intermittently without being able to compensate. The mobile terminal device 1 of the present embodiment has a transmission pattern that is continuous in chronological order. Since the transmission packet after the packet is thinned out is transmitted, the interrupted voice is output from the telephone device of the communication partner. As a result, it is possible to create the same situation as the situation where the communication state is very bad, and the user of the telephone device can end the call while making the other party think that the communication state is very bad.

 The mobile terminal device 1 according to another embodiment of the present invention transmits a predetermined ratio of transmission packets generated among the generated transmission packets, and based on a predetermined ratio of reception packets received. Output audio. The call processing of the mobile terminal device 1 of the present embodiment is different in the transfer destination step to be transferred after the process of step a8 of the process shown in the flowchart of FIG. 3 is completed, and the other processes are the same.

 FIG. 14 is a flowchart showing communication processing of the mobile terminal device 1. The processing from step mO to step m7 is the same as the processing from step aO to step a7, respectively, and the processing from step m9 to step ml1 is the same as the processing from step a9 to step al1, respectively. Description of the processing to be performed is omitted.

 In step m8, since it is the timing for thinning out, the main control unit 7 discards the transmission packet generated in step m4 without giving it to the communication control unit 2, and proceeds to step mlO. When the processing of step m8 is completed in this way, the process proceeds to step mlO without proceeding to step m9. Therefore, at the timing of thinning out the transmitted packet, the received packet is decoded and output from the speech power 5. Do not perform step m9.

 According to the mobile terminal device 1 of the present embodiment described above, when the transmission packet is thinned, the received packet is thinned at the same thinning rate, and the voice is output based on the received packet after thinning. Even if a part of the generated transmission packet is transmitted intermittently, the user of the mobile terminal device 1 is not able to confirm how much discontinuous voice the other party is listening to. If the communication status is bad with certainty, the call cannot be terminated while making the other party think. In this embodiment, the user can confirm how his / her voice reaches the communication partner V by listening to the interrupted voice of the communication partner. You can end the call while reminding the other party that it is bad!

The mobile terminal device 1 according to another embodiment of the present invention starts discarding transmission packets When the predetermined time elapses, the communication is automatically terminated. In the communication process of the mobile terminal device 1 of the present embodiment, the process shown in the flowchart of FIG. 3 described above includes a process for determining whether or not a predetermined time has passed, and the mobile terminal device of each of the above-described embodiments. The process of thinning out is different from that of device 1.

 FIG. 15 is a flowchart showing communication processing of the mobile terminal device 1. FIG. 16 is a flowchart showing the thinning determination process.

 Since the processing from step pi to step p3 of the thinning determination processing shown in FIG. 16 is the same as the processing from step bl to step b3 shown in FIG. 4, the description of the overlapping processing is omitted. In step p2, when the main control unit 7 sets the inter-bow I flag to ON and proceeds to step p4, the main control unit 7 determines whether or not it is the first decimation after the start of the call. Specifically, when the main control unit 7 determines that the thinning flag is set to ON for the first time after starting a call, the main control unit 7 proceeds to step p5, and if the thinning determination flag has already been set to ON, the step is performed. Move to p6. In step p5, the main control unit 7 starts the call end timer of the time measuring unit 16. The initial value of the call end timer is set in advance by the user operating the operation button unit 9 and stored in the memory 10. Next, the process proceeds to step p6, and the thinning determination process ends. By performing the process shown in Fig. 16, the call end timer starts when decimation starts, and the transmission time starts when the transmission packet is discarded.

 In the communication process shown in FIG. 15, a process for determining whether or not the call end timer has timed out is added between steps a9 and a10 of the process shown in FIG. The processing from step ηθ to step n9 is the same as the processing from step aO to step a9, and the processing from step ni l and step nl 2 is the same as the processing from step alO and step al l, respectively. A description of the processing is omitted.

When the received packet decoded in step n9 is output as sound from the speaker 5, the process proceeds to step nlO. In step nlO, the main control unit 7 determines whether or not the call end timer has timed out. When the call end timer is started and it is determined that a predetermined time has elapsed, the main control unit 7 performs processing to end the call. Then go to step nl2 to end the communication process. In step nlO, if the call end timer has not timed out, proceed to step nl 1 to continue the call loop. According to the mobile terminal device 1 of the present embodiment described above, after the main control unit 7 starts to output transmission packets intermittently in chronological order, it automatically communicates with other telephone devices after the elapse of a predetermined time. Communication ends. In other words, after creating the same situation as the situation in which the communication state is very bad, when a predetermined time elapses, the communication with the other telephone device is terminated even if the user of the telephone device does not perform any special operation. This eliminates the need for the user of the mobile terminal device 1 to end communication with another telephone device, and improves the convenience of the user of the mobile terminal device 1.

 The mobile terminal device 1 according to another embodiment of the present invention determines whether or not to discard the transmission packet based on whether or not it is registered in the phone book data as a thinning target for discarding the transmission packet. to decide.

 FIG. 17 is a flowchart showing communication processing of the mobile terminal device 1. FIG. 18 is a flowchart showing a process in which the main control unit 7 registers a communication partner to be thinned out in the telephone directory. When the user of the mobile terminal device 1 operates the operation button unit 9 and information indicating that the terminal of a specific communication partner is registered as a thinning target is entered, the process proceeds from step rO to step rl. In step rl, the main control unit 7 updates the telephone directory data stored in the memory 10 and registers the input terminal of the specific communication partner as a thinning target. Next, the process proceeds to step r2, and the process of registering the target of the space bow I in the phone book is finished.

The processing from step qO to step q4 of the communication processing shown in FIG. 17 is the same as the processing from step aO to step a4 in FIG. When a transmission packet is generated in step q4, the process proceeds to step q5. In step q5, the main control unit 7 determines whether or not the communication partner terminal is registered as a thinning target in the phone book data. If it is registered as the target of the space bow I, proceed to step q6. In step q6, the main control unit 7 performs the thinning determination process described above, and proceeds to step q7. In step q7, the main control unit 7 determines whether or not the timing for thinning out transmission packets is determined. If the thinning flag is OFF, the process proceeds to step q8, and if the thinning flag is ON, the process proceeds to step q9. Since the processing from step q8 to step ql2 is the same as the processing from step a7 to step al1 in FIG. 3, the description of the overlapping processing is omitted. According to the mobile terminal device 1 of the present embodiment described above, when communicating with a telephone device corresponding to predetermined telephone number information registered as a thinning target in the phone book data, the communication start force also selects the packet discard mode. And discard the transmission packet with the thinning rate P

. When communicating with a telephone device corresponding to telephone number information that is not registered as a thinning target, all transmission packets generated by selecting the full packet output mode are transmitted. Therefore, only when communicating with a telephone device that corresponds to the predetermined telephone number information, the communication starting power can also make the communication state worse, and the call is terminated while making the other party think that the communication state is bad. be able to.

 The mobile terminal device 1 according to another embodiment of the present invention, for a communication partner registered in the phone book data as a thinning target for discarding a transmission packet, receives a packet discard mode when a predetermined time elapses from the start of communication. Select.

 FIG. 19 is a flowchart showing the communication process of the mobile terminal device 1. The communication processing of the mobile terminal device 1 of the present embodiment is performed in step s6 for determining whether or not a predetermined time has elapsed between the processing in step q5 and the processing in step q6 of the communication processing shown in FIG. This is an addition of processing. The processing from step sO to step s5 is the same as the processing from step qO to step q5, and the processing from step s7 to step sl3 is the same as the processing from step q6 to step ql2. A description of the processing is omitted.

When the main control unit 7 determines in step s5 that the communication partner terminal is registered as a thinning target in the phone book data, the process proceeds to step s6. In step s6, the main control unit 7 starts communication and determines whether or not a predetermined time has elapsed. If the predetermined time has elapsed, the main control unit 7 proceeds to step s7, and the predetermined time has elapsed. Otherwise, go to step s9. If the main control unit 7 determines in step s5 that the terminal of the communication partner is registered in the phone book data and is not registered as a target, the process proceeds to step s9. According to the mobile terminal device 1 of the present embodiment described above, the packet discard mode is selected from the middle of communication when communicating with the telephone device corresponding to the predetermined telephone number information registered as the thinning target in the phone book data. Is done. Therefore, when communicating with a telephone device corresponding to predetermined telephone number information, the communication state must be simulated in the middle of communication. It can be made worse, and the call can be terminated while making the other party think that the communication status is bad.

 When a registration command for registering a thinning target during a call with another terminal is input, the mobile terminal device 1 according to another embodiment of the present invention registers the other terminal during the call as a thinning target. For example, if the number command “4” on the numeric keypad is pressed during a call and a registration command is input, the other terminals in the call are registered as thinning targets. Since the communication process of the mobile terminal device 1 of the present embodiment is the same as the process shown in the flowchart of FIG. 17, the description of the overlapping process is omitted.

 FIG. 20 is a flowchart showing a process of changing the registered contents of the phone book to the thinning target. If the number “4” button on the numeric keypad is pressed during a call loop, an interrupt process occurs and the process goes from step tO to step tl. In step tl, the main control unit 7 changes the content of whether or not it is a thinning target registered in the telephone book data of the communication partner to the thinning target, proceeds to step t2, and ends the interrupt process.

 According to the mobile terminal device 1 of the present embodiment described above, when the user operates the operation button unit 9 during communication, the communication partner is registered in the phone book data as a thinning target. As a result, when the next communication with the communication partner registered as the target of thinning is performed, the packet discard mode is selected, and the call can be terminated while making the other party think that the communication state is bad in the next communication. . In this way, a specific communication partner can be registered as a thinning target without any special operation by the user, so that convenience for the user is improved.

 The mobile terminal device 1 according to another embodiment of the present invention is registered in the phone book data and is not set to notify! The packet full output mode is selected for the communication partner and the phone book data is selected. Select the packet discard mode for the communication partner that is not registered or the communication partner that is set to non notification.

 FIG. 21 is a flowchart showing the communication process of the mobile terminal device 1. FIG. 22 is a flowchart showing a process in which the main control unit 7 registers the telephone number of the communication partner in the telephone directory data.

A user of the mobile terminal device 1 operates the operation button unit 9 to connect to a specific communication partner terminal. When information indicating the corresponding telephone number is input, the process proceeds from step νθ to step vl. In step vl, the main control unit 7 updates the telephone book data stored in the memory 10 and registers the telephone number corresponding to the input terminal of the specific communication partner in the telephone book data. Then, go to step v2 to finish the process.

 The communication process shown in FIG. 21 is obtained by replacing the process of step q5 with the process of steps u5 and u6 in the communication process of FIG. The processing from step uO to step u4 is the same as the processing from step qO to step q4, and the processing from step u7 to step u13 is the same as the processing from step q6 to step ql2. The description of is omitted.

 When the main control unit 7 generates a transmission packet in step u4, the process proceeds to step u5. In step u5, based on the received packet, the main control unit 7 determines whether or not the other party's telephone number is not notified of the telephone number (non-notification setting is set). Move to u6. If not notified, move to step u7.

 In step u6, the main control unit 7 specifies the telephone number of the communication partner from the received packet, and determines whether this telephone number is registered in the telephone directory data. If the specified telephone number is not registered in the phone book data, the process proceeds to step u7 if not, and if the specified telephone number is registered, the process proceeds to step u9.

 According to the mobile terminal device 1 of the present embodiment described above, the packet discard mode is selected for the communication partner registered in the phone book data, such as V, N, or non-notification. As a result, for example, in communication with a telephone device by a stranger or the like, the call can be terminated while making the other party think that the communication state is bad.

 When a selection command for setting a thinning operation state is input during a call, the mobile terminal device 1 according to another embodiment of the present invention stores the time elapsed from the start of the call until the selection command is input. When the memorized time elapses in the next call, the sending packet starts to be discarded.

FIG. 23 is a flowchart showing the communication process of the mobile terminal device 1. FIG. 24 is a flowchart showing the process of registering the elapsed time when the selection command is input in the phone book data. When the number key “1” or “2” button on the numeric keypad is pressed during a call loop and a selection command is input, an interrupt process occurs and the process proceeds from step χθ to step xl. In step xl, the main control unit 7 determines whether or not the information indicating the operation permission state has been input. If it is determined that the information indicating the operation permission state has been input, the main control unit 7 proceeds to step x2 and operates. If it is determined that the prohibit state is entered, the process proceeds to step x3. Specifically, if it is determined that the numeric key “1” is depressed, the process proceeds to step x2, and if it is determined that the numeric key “2” is depressed, the process proceeds to step x3.

 In step x2, the main control unit 7 sets the thinning operation state to the permitted state, and proceeds to step x4. In step x4, the main control unit 7 registers the time elapsed from the start of communication until the operation state is set to the permitted state in the telephone directory data in correspondence with the communication partner, and proceeds to step x5. In step x3, the main control unit 7 sets the thinning-out operation state to the prohibited state, and proceeds to step x5. In step x5, interrupt processing ends and interrupt processing ends.

 The communication process shown in FIG. 23 is obtained by adding the process of step w6 to the communication process of FIG. 9 described above. The processing from Step wO to Step w5 is the same as the processing from Step fO to Step f5, and the processing from Step w7 to Step wl 3 is the same as the processing from Step f6 to Step f12. Description of the processing to be performed is omitted.

 In step w5, the main control unit 7 determines whether or not the thinning operation is permitted. If the thinning operation is prohibited, the process proceeds to step w6, and if the thinning operation is permitted, step w7. Migrate to In step w6, the main control unit 7 passes the call time when the previous thinning-out process was started for the terminal currently communicating based on the phone book data and the information indicating the call time given from the time measuring unit 16 Judge whether or not. If the call time that started the thinning process last time has passed, the process moves to step w7, and if it has passed, the process moves to step V9.

According to the mobile terminal device 1 of the present embodiment described above, the packet discard mode is selected when the communication time during which the previous packet discard mode was selected during communication has elapsed. As a result, the communication time when the packet discard mode was selected in the previous communication without requiring any special user operation is automatically set to the communication time when the packet discard mode is started. Therefore, convenience for the user is improved.

 The mobile terminal device 1 according to another embodiment of the present invention performs a transmission packet thinning process in a predetermined time zone.

 FIG. 25 is a flowchart showing the communication process of the mobile terminal device 1. FIG. 26 is a flowchart showing the process of setting the thinning operation permission time zone.

 When the user of the mobile terminal device 1 operates the operation button unit 9 and time zone information, which is information specifying the time zone in which the thinning operation is permitted, is input, the process proceeds from step ζθ to step zl. In step zl, the main control unit 7 sets the input time zone as the thinning operation permission time zone. Next, the process proceeds to step z2 to finish the process of setting the thinning operation permission time zone.

 The communication process of the mobile terminal device 1 shown in FIG. 25 is obtained by replacing the process of step f5 of FIG. 9 with the process of step y5 for determining whether or not it is the thinning operation permission time zone. The processing from step y0 to step y4 is the same as the processing from step fO to step f4, and the processing from step y6 to step y12 is the same as the processing from step f6 to step f12. Explanation of overlapping processing is omitted.

 When a transmission packet is generated in step y4, the process proceeds to step y5. In step y5, the main control unit 7 determines whether or not the current time is included in the thinning-out operation permission time zone based on the time counted by the time counting unit 16. If the current time is included in the thinning-out operation permitted time zone, the process proceeds to step y6. If the current time is not included in the thinning-out operation permitted time period, the process proceeds to step y8.

According to the mobile terminal device 1 of the present embodiment described above, the packet discard mode is selected if the current time is included in the intermission operation permitted time zone, and the current time is not included in the decimation operation permitted time zone. , The full packet output mode is selected. Since the mobile terminal device 1 outputs a predetermined number of transmission packets in the time zone indicated by the time zone information, the communication state of the mobile terminal device 1 is simulated in the time zone according to the operation of the operation button unit 9 by the user. Can be aggravated. For example, if there is a time zone in which the user does not want to talk, by entering this time zone, the communication status of this time zone can be artificially deteriorated. While communicating with the other party that the communication status is bad You can end the story.

 The mobile terminal device 1 according to another embodiment of the present invention functions as a videophone device.

Industrial applicability

 According to the present invention, sound is converted into an electrical signal by the sound data generating means. The packet processing means packetizes the voice data generated by the voice data generating means. The packet processing means can output a predetermined number of transmission packets among the plurality of generated transmission packets. The transmission packet output from the packet processing means is transmitted to the communication network by the transmission / reception means. The control means transmits the transmission packet and receives the reception packet. The audio data included in the received packet is output as audio from the output means. As a result, telephone communication with other telephone devices becomes possible.

 Since the packet processing means intermittently outputs a part of all the generated transmission packets, a part of all the generated transmission packets are intermittently transmitted from the telephone device. Other telephone devices that have received the transmission packet transmitted from this telephone device cannot reproduce the voice before being converted by the voice data generation means because some transmission packets are missing. Is choppy.

For example, if the telephone device that transmits the transmission packet is located far away from the base station and cannot transmit the transmission packet to the base station, or if the packet is congested, the communication status is poor. In some situations, the audio is choppy. In this way, the telephone device transmits a part of all generated transmission packets intermittently. Thus, it is possible to create the same situation as the situation where the communication state is bad. As a result, the user of the telephone device can end the call while making the other party think that the communication state is poor.

 In addition, the telephone device of the present invention can intermittently transmit a part of transmission packets generated by using a hardware configuration necessary for telephone communication, and a noise generation circuit as in the prior art. Further, it is not necessary to add a configuration such as a noise insertion circuit. This makes it possible to create the same situation as a situation where the communication state is poor without complicating the configuration of the device.

 According to the present invention, the packet processing means packetizes the audio data in time series and outputs a plurality of transmission packets that are continuous in time series. In order to compensate for the lost packet, another telephone device that receives the transmitted packet may copy the data of the packet immediately before the lost packet in time series and output it as voice. In this way, other telephone devices supplement the missing packets to prevent the voice from being interrupted, but if they do not receive time-sequentially transmitted packets, they will compensate for the missing packets. The sound is output intermittently without being completely cut. This makes it possible to create the same situation as a situation where the communication state is very bad, and the user of the telephone device can end the call while making the other party think that the communication state is very bad. According to the present invention, the transmission / reception means gives the received packet to the packet processing means. The bucket processing means outputs a predetermined ratio of received packets without outputting all received packets of the given received packets. The output means outputs the received packet output from the packet processing means as voice. Since a part of all received packets received by the transmission / reception means is output as voice from the output means, the voice of the communication partner is interrupted. As a result, the user of the telephone device can confirm how much the communication partner listens to and receives the choppy voice.

Even if a part of the generated transmission packet is transmitted intermittently, if there is no way for the communication partner to listen to and check how interrupted the voice is, the user of the telephone device If the communication condition is bad with certainty, the call cannot be terminated while making the other party think. According to the present invention, the user of the telephone device By listening to, you can check how your voice reaches the other party and confirm the power, so you can confidently terminate the call while making the other party think that the communication status is bad .

 According to the present invention, after the packet processing means starts outputting transmission packets intermittently in time series, communication with another telephone device automatically ends after a predetermined time has elapsed. In other words, after creating the same situation as the situation where the communication state is very bad, when a predetermined time elapses, the communication with the other telephone device is terminated even if the user of the telephone device does not perform any special operation. As a result, the user of the telephone device does not need to perform an operation for ending communication with the other telephone device, and the convenience of the user of the telephone device is improved.

 According to the present invention, since the packet processing means determines the predetermined ratio based on the random number, the ratio of the transmission packet transmitted from the telephone device among the generated transmission packets changes randomly. As a result, the frequency at which audio output from other telephone devices is interrupted changes randomly. Since the actual communication state changes with time, the frequency at which voice is interrupted also changes with time in actual communication. The telephone device of the present invention can create a situation close to the actual communication state by randomly changing the frequency at which the voice output from other telephone device power is interrupted in the same manner as in actual communication. As a result, the user of the telephone device can end the call while making the other party think that the communication state is bad!

 According to the present invention, since the packet processing means decreases the predetermined ratio as the communication time elapses, the ratio of transmission packets transmitted from the telephone device among the generated transmission packets decreases. As a result, the frequency at which audio output from other telephone devices is interrupted increases with time. In actual communication, as the communication state deteriorates, the frequency of voice interruptions increases with time. The telephone device of the present invention can create a situation close to the situation where the communication state is deteriorated by increasing the frequency at which the voice output from other telephone devices is interrupted over time. As a result, the user of the telephone device can end the call while making the other party think that the communication state has deteriorated.

According to the present invention, the packet processing means preliminarily generates a plurality of generated transmission packets. A packet discard mode that outputs a predetermined percentage of transmission packets and a full packet output mode that outputs all of the generated transmission packets can be selected based on a selection command input from the input means. As a result, the packet discard mode and the full packet output mode are switched according to the operation of the input means by the user, and the convenience for the user is improved. According to the present invention, the packet processing means sets the predetermined ratio according to the information indicating the predetermined ratio in which the input means power is also input, so that the transmission processing generated in response to the user's operation of the input means Sets the ratio of packets sent from the telephone device out of the packets. Therefore, the user can freely set the communication state of the telephone device in a pseudo manner by operating the input means, and the convenience for the user is improved.

According to the present invention, the packet processing means sets the predetermined ratio according to the information indicating that the predetermined ratio at which the input means force is also input is reduced, so that according to the operation of the user's input means, Of the transmission packets to be generated, the percentage of transmission packets transmitted from the telephone device decreases. Therefore, the user can artificially deteriorate the communication state of the telephone device by operating the input means, and the convenience for the user is improved. According to the present invention, since the packet processing means outputs a predetermined percentage of transmission packets in the time zone represented by the time zone information input from the input means, the time zone according to the operation of the user input means Therefore, the communication state of the telephone device can be artificially deteriorated. For example, if there is a time zone in which the user does not want to talk, the communication status of this time zone can be artificially deteriorated by entering this time zone. According to the present invention, the packet processing means selects the packet discard mode when communicating with the telephone device corresponding to the predetermined telephone number information. Therefore, when communicating with a telephone device corresponding to the predetermined telephone number information, the communication state can always be artificially deteriorated, and the call can be terminated while making the other party think that the communication state is bad! . According to the present invention, when the packet processing means communicates with the telephone device corresponding to the predetermined telephone number information, the packet discard mode is selected for the communication start time. Therefore, when communicating with a telephone device corresponding to the predetermined telephone number information, Therefore, it is possible to make the communication state worse in a pseudo manner, and the call can be terminated while making the other party think that the communication state is bad.
