The call control unit 7 executes call processing in accordance with an instruction from the CPU 5.

  The setting switch SW is a switch for setting one call mode from a plurality of call modes.

FIG. 3 is a diagram illustrating the setting switch SW based on the embodiment.
As shown in FIG. 3, a slide switch that is set by sliding the slider 50 is shown as the setting switch SW. The call mode can be set by aligning the slider 50 at a position corresponding to each of the three call modes M1 to M3.

FIG. 4 is a diagram illustrating a plurality of call modes based on the embodiment.
Referring to FIG. 4, in this example, a plurality of call modes are provided. As an example, three call modes are provided. The call mode can be set for each slave unit 2. Specifically, one call mode is set from the plurality of call modes M1 to M3 by the setting switch SW.

  The call mode M1 executes normal call processing. The call mode M2 executes a call process that does not require a response acceptance process. The call mode M3 executes a call process that does not require a response acceptance process and a call process.

<Call mode M1>
Perform normal call processing.

  More specifically, when the answer / call button 200 is selected on the child device 2 without selecting the designation button 202, a call command from the child device 2 to the parent device 10 is transmitted. The base unit 10 receives the call command from the handset 2 and executes call processing. Specifically, base unit 10 notifies that there is a call. When the user selects the answer / call button 100, the call is established. Specifically, an audio signal input from the microphone 8 of the child device 2 is transmitted to the parent device 10. And it outputs from the speaker 19 of the main | base station 10. FIG. In addition, an audio signal input from the microphone 18 of the parent device 10 is transmitted to the child device 2. And it outputs from the speaker 9 of the subunit | mobile_unit 2. FIG. Thereby, a two-way call becomes possible. When the call is to be ended, the call can be ended by selecting again the answer / call button 100 of the parent device 10 or the response / call button 200 of the child device 2.

  In the handset 2, when the response / call button 200 is selected after selecting the designation button 202, the number and call command for the other designated handset are transmitted to the base unit 10.

  The base unit 10 receives the number for the designated other handset and identifies the handset 2 to be transmitted with reference to the memory 13. The base unit 10 relays and transmits the received call instruction to the specified handset 2. For example, when the user of the handset 2A selects the designation button 202 of the number “2” and selects the answer / call button 200, a call command is transmitted to the handset 2B via the base unit 10. The Then, the calling process is executed in the slave unit 2B. Alternatively, when the user of the slave unit 2B selects the designation button 202 of the number “1” and selects the answer / call button 200, a call command is transmitted to the slave unit 2A via the master unit 10. The Then, the calling process is executed in the slave unit 2A. The same applies to the calling process using other designation buttons.

  For example, the handset 2B that has received the call instruction notifies that there is a call. When the user selects the answer / call button 200, the call is established. Specifically, an audio signal input from the microphone 8 of the child device 2B is transmitted to the child device 2A via the parent device 10. And it outputs from the speaker 9 of 2 A of subunit | mobile_units. In addition, an audio signal input from the microphone 8 of the child device 2A is transmitted to the child device 2B via the parent device 10. And it outputs from the speaker 9 of the subunit | mobile_unit 2B. As a result, a two-way call between the slave units 2A and 2B becomes possible.

  When the answer / call button 100 is selected after selecting the designation button 102 in the parent device 10, a call command is transmitted to the designated child device. For example, when the user selects the designation button 102 with the number “1” and selects the answer / call button 100, a call command is transmitted to the child device 2A. Then, the calling process is executed in the slave unit 2A.

  For example, the slave unit 2A that has received the call instruction notifies that there is a call. When the user selects the answer / call button 200, the call is established.

<Call mode M2>
Execute call processing that does not require response reception processing.

For example, a case where the handset 2B is set to the call mode M2 will be described.
Specifically, the handset 2B that has received the call instruction notifies that there is a call. In the call mode M2, the call is established without accepting selection of the answer / call button 100.

  Specifically, an audio signal input from the microphone 18 of the parent device 10 or the microphone 8 of the other child device 2 is transmitted to the child device 2B. And it outputs from the speaker 9 of the subunit | mobile_unit 2B. In addition, an audio signal input from the microphone 8 of the child device 2B is transmitted to the parent device 10 or another child device 2. And it outputs from the speaker 19 of the main | base station 10, or the speaker 9 of the other subunit | mobile_unit 2. FIG.

That is, a call is established upon receipt of a call command.
By this processing, it is possible to easily establish a call in that an operation by the user of the slave unit 2B is not necessary. For example, even when the user of the handset 2B is difficult to operate (for example, a situation where care is required or a situation where the hands cannot be released), a call can be easily established and two-way communication is possible. Become.

The same settings can be made for other slave units.
<Call mode M3>
Execute call processing that does not require response reception processing. In addition, call processing that does not require a call operation is executed.

For example, the case where the handset 2B is set to the call mode M3 will be described.
Specifically, the handset 2B that has received the call instruction notifies that there is a call. In the call mode M3, the call is established without accepting selection of the answer / call button 100.

  Specifically, an audio signal input from the microphone 18 of the parent device 10 or the microphone 8 of the other child device 2 is transmitted to the child device 2B. And it outputs from the speaker 9 of the subunit | mobile_unit 2B. In addition, an audio signal input from the microphone 8 of the child device 2B is transmitted to the parent device 10 or another child device 2. And it outputs from the speaker 19 of the main | base station 10, or the speaker 9 of the other subunit | mobile_unit 2. FIG.

That is, a call is established upon receipt of a call command.
Further, in the case of the call mode M3, a process of automatically making a call to the parent device 10 is executed when a volume of a predetermined amount or more is detected.

  Specifically, the volume input to the microphone 8 of the slave unit 2B is detected, and it is determined whether there is an input of a volume higher than a predetermined amount. When it is determined that there is an input of a sound volume of a predetermined amount or more, a calling instruction is transmitted from the child device 2B to the parent device 10. The base unit 10 receives the call command from the handset 2B and executes the call process. Specifically, base unit 10 notifies that there is a call. When the user selects the answer / call button 100, the call is established.

  With this process, it is possible to easily establish a call without requiring an operation by the user of the handset 2B at the time of answering and calling. For example, even when the user of the handset 2B is difficult to operate (for example, a situation where care is required or a situation where the hands cannot be released), a call can be easily established and two-way communication is possible. Become.

<Processing flow>
FIG. 5 is a flowchart of call processing in the handset 2 based on the embodiment.

  Referring to FIG. 5, slave unit 2 determines whether there is a call (step S2). The subunit | mobile_unit 2 judges whether the call instruction | command from the other subunit | mobile_unit 2 was received from the main | base station 10 or via the parent | base unit 10. FIG.

  In step S2, handset 2 maintains that state until there is a call, and if it is determined that there is a call (YES in step S2), it determines whether or not call mode M1 is set (step S2). S4). The subunit | mobile_unit 2 judges whether the slider 50 is set to the position corresponding to call mode M1 by setting switch SW.

  If it is determined in step S4 that the handset 2 is set to the call mode M1 (YES in step S4), the handset 2 notifies that there is a call (step S6). The subunit | mobile_unit 2 outputs a ringing tone from the speaker 9. FIG.

  Next, the subunit | mobile_unit 2 judges whether there exists reception of a response (step S8). Specifically, handset 2 determines whether selection of answer / call button 200 has been accepted.

  If it is determined in step S8 that the handset 2 has received a response (YES in step S8), the handset 2 establishes a call (step S10). When the handset 2 accepts the selection of the answer / call button 200, the handset 2 establishes a call and executes transmission / reception of an audio signal with the base unit 10. Alternatively, audio signals are transmitted / received to / from another child device 2 via the parent device 10.

  Next, it is determined whether or not the call process has been completed (step S12). The subunit | mobile_unit 2 judges whether selection of the response / call button 200 was received again. Or the subunit | mobile_unit 2 judges whether the telephone call was complete | finished by operation of the other party who is carrying out a telephone call.

  In step S12, when the handset 2 determines that the call process has been completed (YES in step S12), the process ends (end).

  On the other hand, if it is determined in step S8 that the handset 2 has not received a response (NO in step S8), the process is terminated (END). For example, if the handset 2 does not accept the selection of the answer / call button 200 within a predetermined period after notifying the ringing tone, the handset 2 determines that no response is accepted and ends the process.

  If the handset 2 determines in step S4 that the call mode M1 is not set (NO in step S4), the process proceeds to step S14. The case where it is determined that the call mode M1 is not set is the case where the call mode M2 or the call mode M3 is set.

  In step S14, the subunit | mobile_unit 2 alert | reports that there exists a call (step S14). The subunit | mobile_unit 2 outputs a ringing tone from the speaker 9. FIG.

  And the subunit | mobile_unit 2 establishes a telephone call (step S16). When the handset 2 receives the calling instruction, the handset 2 establishes a call and executes transmission / reception of a voice signal with the base unit 10. Alternatively, audio signals are transmitted / received to / from another child device 2 via the parent device 10.

Then, the process proceeds to step S12. The subsequent processing is the same.
With this process, it is possible to easily establish a call in that the user of the handset 2 is not required in the case of the call mode M2 or the call mode M3 when responding to a call command from another handset. It is.

FIG. 6 is a flowchart of the calling process of the handset 2 based on the embodiment.
Referring to FIG. 6, handset 2 determines whether call mode M3 is set (step S20). The subunit | mobile_unit 2 judges whether the slider 50 is set to the position corresponding to call mode M3 by setting switch SW.

  In step S20, if the handset 2 determines that the call mode M3 is set (YES in step S20), the handset 2 determines whether the input volume is equal to or higher than a predetermined volume (step S22). Specifically, the call control unit 7 of the handset 2 detects the input volume input to the microphone 8 and determines whether or not the input volume is equal to or higher than a predetermined volume.

  If it is determined in step S22 that the input volume is equal to or higher than the predetermined volume (YES in step S22), the handset 2 performs a call (step S24). When the call control unit 7 determines that the input volume input to the microphone 8 is equal to or higher than the predetermined volume, the call control unit 7 notifies the CPU 5. The CPU 5 transmits a calling instruction to the parent device 10 via the communication I / F 6 in accordance with the notification from the call control unit 7.

Then, the process ends (END).
In base unit 10, a call is established by selecting answer / call button 100 for the call command.

  On the other hand, if it is determined in step S20 that the call mode M3 is not set (NO in step S20), the handset 2 determines whether there is a call instruction (step S26). Specifically, handset 2 determines whether selection of response / call button 200 is accepted along with selection of designation button 202. The subunit | mobile_unit 2 judges whether selection of the answer / call button 200 was received without selection button 202 selection.

  The subunit | mobile_unit 2 maintains the state until there exists a call instruction | indication, and when it is judged that there exists a call instruction | indication (in step S26 YES), a call is performed (step S24). Specifically, the slave unit 2 transmits a call command from the slave unit 2 to the master unit 10 when the selection of the response / call button 200 is accepted without selecting the designation button 202. After receiving the designation button 202, the child device 2 transmits a call instruction for the other designated child device to the parent device 10 when the selection of the response / call button 200 is accepted.

Then, the process ends (END).
With this processing, in the call mode M3, it is possible to easily establish a call in that an operation by the user of the handset 2 is not required when a call is made to the base unit 10.

  In this example, the case where the call command is transmitted only to the parent device 10 in the call mode M3 has been described. However, the present invention is not limited to this, and the call command is specified by specifying another specific child device 2. Alternatively, the call command may be transmitted to the parent device 10 and all the other child devices 2.

  Note that the ringing tone is not limited to one type, and a plurality of types can be provided, and different types of ringing sounds can be set corresponding to the parent device 10 or the child device 2, respectively.

  The case where wireless communication is performed between the parent device 10 and the child device 2 has been described. However, when the distance between the parent device 10 and the child device 2 becomes longer and the distance between the parent device 10 and the child device 2 exceeds the wireless communication range. You may make it alert | report to the main | base station 10, the subunit | mobile_unit 2, or both that the range of radio | wireless communication is exceeded.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
