<First Embodiment>
[Outline and configuration]
FIG. 1 is a diagram illustrating a communication environment of the terminal device 1 according to the first embodiment. The terminal device 1 makes a call with the telephone 90 or the like via the radio base station 80 or the exchange 85. The telephone 90 is a telephone in a call center, for example, and is operated by the operator O. When the operator O receives an incoming call from the terminal device 1 and listens to a request from the user of the terminal device 1 (for example, a setting change of the terminal device 1), the operator O outputs a DTMF signal for remotely operating the terminal device 1. The telephone 90 is operated to transmit to the terminal device 1 using a voice line. The contents requested for the remote operation are assumed to be complicated or difficult for a general user, such as setting of Wi-Fi communication or starting of a specific application program.

  FIG. 2 is a configuration diagram illustrating an example of a functional configuration of the terminal device 1 according to the first embodiment. The terminal device 1 includes, for example, a wireless communication unit 10, a call unit 20, a speaker 22, a microphone 24, an operation unit 30, a display unit 32, a DTMF determination unit 40, a DTMF interpretation unit 42, and a telephone directory. A registration unit 44, a control unit 46, and a storage unit 50 are provided.

  The radio communication unit 10 includes a transmission / reception antenna, an encoding unit, a decoding unit, and the like, and performs radio communication with the radio base station 80. The call unit 20 includes, for example, an A / D converter and a D / A converter, converts a signal input from the wireless communication unit 10 into an audio signal and outputs it to the speaker 22, or a sound collected by the microphone 24. The voice signal based on the above is converted into a signal for wireless communication and output to the wireless communication unit 10.

  The operation unit 30 and the display unit 32 are integrally configured as a touch panel, for example. The operation unit 30 may include buttons, switches, and the like. A user operation performed on the operation unit 30 is output to the control unit 46, and the display content of the display unit 32 is determined by the control unit 46.

  The DTMF determination unit 40 determines whether or not the voice input / output by the call unit 20 (including both the voice based on the signal input from the wireless communication unit 10 and the voice input to the microphone 24) includes a DTMF signal. Determine whether. The DTMF signal has a frequency in the voice band that is output by synthesizing a low group frequency sine wave and a high group frequency sine wave by selecting one frequency from the low group frequency and the high group frequency. Signal (audio signal). The DTMF signal can represent 16 types of signals such as numbers “0” to “9” and “*”, “#”, “A”, “B”, “C”, and “D”. The terminal device 1 handles, for example, 12 types (numbers “0” to “9” and “*” “#”) excluding “A”, “B”, “C”, and “D”. When the user touches or presses down the 12 types of keys, a DTMF signal in which frequencies corresponding to the keys are combined is generated and transmitted to the telephone of the other party.

  The DTMF determination unit 40 performs, for example, discrete Fourier transform (DFT) on different frequency components on data for a predetermined time of the input audio signal, and thereby each frequency component used in the DTMF signal. Detect the intensity of. The DTMF determination unit 40 determines whether or not a DTMF signal has been received from the detected intensity of each frequency component, determines the type of the received DTMF signal, and outputs it to the DTMF interpretation unit 42.

  The DTMF interpretation unit 42 searches the DTMF correspondence table stored in advance in the DTMF correspondence table storage unit 52 using the type of the DTMF signal input from the DTMF determination unit 40 and generates a control signal for the terminal device 1. . In the DTMF correspondence table, the content of control for the terminal device 1 corresponding to the type of DTMF signal is described. For example, if the DTMF signal is “1010”, the relationship “change Wi-Fi communication setting to ON” is described in the DTMF correspondence table.

  The phone book registration unit 44 receives a DTMF signal from another device (for example, the telephone 90), and when the control signal is generated by the DTMF interpretation unit 42, an item for transmitting the received DTMF signal is displayed as a phone book data storage unit. It registers in the telephone book stored in 54. Details will be described later.

  The control unit 46 actually performs control according to the control signal input from the DTMF interpretation unit 42. In addition to the above, the control unit 46 performs outgoing / incoming control, telephone book editing control, and the like. The control unit 46 includes, for example, an OS (Operating System), transmits the contents of operations performed on the operation unit 30 to each function unit, and receives the contents displayed on the display unit 32 from each function unit.

[Remote operation playback]
As described above, the terminal device 1 according to the embodiment can receive a remote operation by receiving a DTMF signal from another device. However, control that calls a call center or the like to request remote operation is often complicated or difficult to perform manually. Therefore, when the state set by remote control returns to the state before setting for some reason, it may be necessary to call the call center again. As a result, convenience may be reduced.

  On the other hand, the terminal device 1 according to the present embodiment outputs a DTMF signal received from another device to the speaker 22 of the own device, collects the sound with the microphone 24, and performs DTMF determination and interpretation. Thus, it is possible to create a state where the remote operation is received again. Thereby, the terminal device 1 of this embodiment can improve the convenience.

  The DTMF signal received from another device is registered, for example, with an abbreviated dial attached to a telephone directory. When this speed dial is operated, a DTMF signal is output from the speaker 22 in place of a normal telephone call. When a speed dial is operated during a telephone call, a DTMF signal may be transmitted to the telephone of the other party.

[Processing flow]
Hereinafter, the flow of processing related to such remote operation reproduction will be described. FIG. 3 is an example of a flowchart showing a flow of processing executed by the terminal device 1 according to the first embodiment. The process of the flowchart of FIG. 3 is repeatedly executed at a predetermined cycle, for example.

  First, the DTMF determination unit 40 determines whether or not a DTMF signal is detected in either the sound based on the signal input from the wireless communication unit 10 or the sound input to the microphone 24 (step S100). When the DTMF determination unit 40 does not detect the DTMF signal, one routine of this flowchart ends.

  When the DTMF determination unit 40 detects the DTMF signal, the DTMF interpretation unit 42 interprets the signal, generates a control signal, and outputs the control signal to the control unit 46 (step S102). In response to this, the control unit 46 executes control (step S104).

  Next, the phone book registration unit 44 determines whether or not the DTMF signal (DTMF signal received this time) that is the basis of the control is registered in the phone book (step S106). When the DTMF signal received this time is already registered in the telephone directory, one routine of this flowchart is completed.

  If the DTMF signal received this time is not registered in the phone book, the phone book registration unit 44 asks the display unit 32 via the control unit 46 whether or not to register the control by the current remote operation in the phone book. Display is performed (step S108). Then, the telephone directory registration unit 44 determines whether or not a user operation indicating an intention to “register” is performed on the operation unit 30 (step S110). When the user's operation indicating the intention of “registering” is performed on the operation unit 30, the phone book registration unit 44 registers the DTMF signal received this time in the phone book with an abbreviated dial, for example (step S112). ). The DTMF signal registered in the telephone directory may be given additional information that is different from, for example, a telephone call. FIG. 4 is a diagram showing an example of a phone book display screen in which DTMF signals are registered. As shown in FIG. 4, for example, an item for transmitting a DTMF signal is registered in a speed dial list of a telephone directory in a mixed manner with a normal telephone number. In the item, the content of control realized by the DTMF signal may be displayed. Further, not limited to the mode shown in FIG. 4, when a group is registered with a group name such as “DTMF control” in the telephone directory and the group is selected, a list of items for transmitting a DTMF signal is displayed. It may be.

  The DTMF signal is registered in the telephone directory by the processing described above, and when the user subsequently operates the corresponding speed dial, the same DTMF signal as that received is generated and output from the speaker 22. When the user operates the corresponding speed dial, it is set in software (or by a hardware mechanism) so that the same control as when the DTMF signal is interpreted is performed without generating the DTMF signal. May be.

  FIG. 5 is an example of a flowchart showing a flow of processing executed by the terminal device 1 according to the first embodiment. The flowchart of FIG. 5 is started when, for example, a speed dial screen of the phone book is displayed, and forcibly ends when the speed dial screen is closed, in addition to satisfying the following end condition.

  First, the control unit 46 waits until transmission of a DTMF signal is selected from the abbreviated dial (step S150). When the transmission of the DTMF signal is selected, the control unit 46 generates a corresponding DTMF signal (step S152), causes the speaker 22 to output it (step S154), and ends this flowchart. Here, as described above, the same control as when the DTMF signal is simply interpreted may be performed without generating the DTMF signal.

  When the microphone 24 collects the DTMF signal output from the speaker 22, the DTMF signal is detected by the DTMF determination unit 40 (step S100 in FIG. 3). Thereafter, the signal is interpreted and a control signal is generated (step S102) and control is executed (step S104), as in the case of receiving a remote operation. In this case, in the next step S106, it is determined that “already registered in the telephone directory”, and one routine of the flowchart ends. In addition, it is not necessarily limited to performing the process at the time of remote control and the reproduction | regeneration by a common procedure, Each may perform an original procedure.

[Summary]
According to the terminal device 1 and its control program of the present embodiment described above, it is possible to generate a control signal for the own device based on the DTMF signal in accordance with a user operation. As a result, the terminal device 1 according to the present embodiment can reproduce the same control after performing a control by receiving a remote operation using a DTMF signal from another device. Thereby, the terminal device 1 of this embodiment can improve the convenience. In addition, in the call center that is the remote operation source, it is possible to avoid the concentration of inquiries with similar contents.

Second Embodiment
Hereinafter, the terminal device 2 according to the second embodiment will be described. About the structure of the terminal device 2 which concerns on 2nd Embodiment, it may be the same as that of the terminal device 1 of 1st Embodiment, Therefore, FIG. 2 is used and separate description is abbreviate | omitted. In the terminal device 2 according to the second embodiment, the DTMF determination unit 40, the DTMF interpretation unit 42, and the DTMF correspondence table storage unit 52 may be omitted.

  The terminal device 2 according to the second embodiment can register the specific control performed by the device itself by attaching a speed dial to the phone book. The specific control is a control that requires a plurality of steps such as a control for executing a function such as tethering and the like, so that the user operation becomes complicated or difficult to perform manually.

  On the other hand, every time a new operation is performed on the operation unit 30, the terminal device 2 of the second embodiment asks the user whether or not to register the operation in the phone book, and the user intends to register. When an operation indicating is performed, the operation is registered in the phone book. As a result, the user can reproduce the same operation content with a simple operation at any time after performing the operation once. Thereby, the terminal device 2 can improve convenience. The operations that can be registered in the phone book are not limited to all operations, but may be narrowed down to operations that are complicated or difficult to perform in advance.

  FIG. 6 is an example of a flowchart showing a flow of processing executed by the terminal device 2 according to the second embodiment. The process of the flowchart in FIG. 6 is repeatedly executed at a predetermined cycle, for example.

  First, the telephone directory registration unit 44 determines whether or not a specific operation has been performed on the operation unit 30 (step S200). When a specific operation is not performed on the operation unit 30, one routine of this flowchart ends.

  When a specific operation is performed on the operation unit 30, the phone book registration unit 44 determines whether or not the corresponding operation is already registered in the phone book (step S202). If the corresponding operation has already been registered in the telephone directory, one routine of this flowchart ends.

  If the corresponding operation is not already registered in the phone book, the phone book registration unit 44 causes the display unit 32 to display whether to register the current operation in the phone book via the control unit 46. (Step S204). Then, the phone book registration unit 44 determines whether or not a user operation indicating an intention to “register” is performed on the operation unit 30 (step S206). When a user's operation indicating an intention to “register” is performed on the operation unit 30, the phone book registration unit 44 registers the current operation in the phone book with an abbreviated dial, for example (step S208).

  When a specific operation is registered in the phone book by the processing described above and the user later operates the corresponding speed dial, it is considered that the same operation as once performed is performed, and control corresponding to the operation is executed. The As a result, the user can cause the terminal device 2 to perform the same control by an operation simpler than the operation performed previously.

  According to the terminal device 2 of the second embodiment described above, after the user performs an operation once, the same operation content can be reproduced with a simple operation at any time. Thereby, the terminal device 2 can improve convenience.
