[0041]
When receiving the ID, handset 600 transmits ACK, which is a signal indicating that the ID has been received, and function information of handset 600 to base unit 500 (step S12). Specifically, when the control unit 100 of the child device 600 determines that the wireless unit 140 has received the ID from the parent device 500, the control unit 100 stores the ID in the storage unit 130 and the function stored in the storage unit 130. Information and ACK are transmitted to base unit 500 by controlling radio section 140.
[0042]
When receiving the ACK and the function information from the slave unit 600, the master unit 500 determines that the extension of the slave unit has been completed normally and stores the function information of the slave unit 600 in the second storage unit 5 (step S13). ). Specifically, when control unit 1 of base unit 500 detects a signal indicating that the ACK and the function information have been received from radio unit 15, the operation for expanding the handset is terminated and the received function information is stored in the second storage. Stored in section 5.
[0043]
By performing such an operation, the extension of the slave units is completed.
[0044]
The operation during a call after the expansion of the slave units is described below.
[0045]
FIG. 4 is a sequence diagram showing an operation during a call.
[0046]
First, when a call signal is transmitted from handset 600 to base unit 500, ACK is returned from base unit 500 to handset 600 (step S100).
[0047]
Specifically, when control unit 100 on handset 600 side determines that there is a call key pressing operation from input unit 110, it controls radio unit 140 to transmit a calling signal to base unit 500.
[0048]
On the other hand, when the control unit 1 on the base unit 500 side detects a signal indicating that the call signal has been received from the radio unit 15, the control unit 1 sends an ACK that is a response signal indicating that the call signal has been received to the slave unit. The wireless unit 15 is controlled to transmit to 600.
[0049]
Thereafter, base unit 500 and handset 600 shift from the control channel to the call channel.
[0050]
Subsequently, when a call channel transition completion signal is transmitted from slave unit 600 to master unit 500, ACK is returned from master unit 500 to slave unit 600 (step S110).
[0051]
Specifically, control unit 100 on handset 600 side controls radio section 140 to transmit a call channel transition completion signal to base unit 500.
[0052]
On the other hand, when the control unit 1 on the base unit 500 side detects a signal indicating that the transition completion signal has been received from the wireless unit 15, the control unit 1 transmits a response signal (ACK) indicating that the transition completion signal has been received. The wireless unit 15 is controlled to transmit to 600.
[0053]
Subsequently, the control unit 1 of the parent device 500 connects the line L by controlling the network control unit 9.
[0054]
Thereafter, when a dial signal is transmitted from child device 600 to parent device 500, an RBT (Ring Back Tone) signal is transmitted from parent device 500 to child device 600 (step S120).
[0055]
Specifically, when control unit 100 on handset 600 side detects the input of a telephone number from input unit 110, telephone number (dial signal) input from input unit 110 is controlled by controlling radio unit 140. Is transmitted to base unit 500.
[0056]
On the other hand, when the control unit 1 on the base unit 500 side detects a signal indicating that the dial signal has been received from the radio unit 15, the control unit 1 controls the network control unit 9 to send the dial signal to the line L. The ringback tone is transmitted to the slave unit 600 by controlling the wireless unit 15.
[0057]
When the other party answers the call and the line is connected, a call is started between the other party and the child device 600 via the parent device 500 (step S130).
[0058]
Specifically, the control unit 1 of the base unit 500 controls the network control unit 9, the speech network 10, and the radio unit 15 to connect the handset 600 and the base unit 500 wirelessly, A communication path is formed with the handset 600. On the other hand, the control unit 100 of the child device 600 controls the speech network unit 160 and the wireless unit 140 to connect the parent device 500 and the child device 600 wirelessly and to connect the speaker 170 and the microphone 180 to the parent device 500. A communication path is formed between them.
[0059]
When speech speed conversion operation is performed on handset 600 during a call, inquiry is made from handset 600 to base unit 500 as to whether speech speed conversion processing can be performed on base side 500 (step S140).
[0060]
Specifically, when the control unit 100 of the child device 600 determines that there is an operation of the speech speed button from the input unit 110, the control unit 100 controls the wireless unit 140 to inquire whether the speech speed conversion can be performed. (Function inquiry) is transmitted to base unit 500.
[0061]
Subsequently, when there is an inquiry, base unit 500 determines whether it has a speech rate conversion function and transmits the result to handset 600 (step S150).
[0062]
Specifically, when the control unit 1 of the base unit 500 detects a signal indicating that the inquiry signal has been received from the wireless unit 15, the control unit 1 is information stored in the second storage unit when the handset 600 is added. By referring to the function information received from the child device 600 and the function information of the parent device 500, both the function information received from the child device 600 and the function information that the parent device 500 has in advance are converted to speech speed. When it is determined whether or not it includes a function, and it is determined that the speech speed conversion function is included, speech speed conversion processing is performed in accordance with an instruction from the handset 600. Since it does not have a speed conversion function, it is determined that the speech speed conversion function is not included in the function information of the base unit 500, and the wireless section 15 is controlled to indicate that the speech speed conversion function is not included. Information (inquiry response) to handset 600 To trust.
[0064]
Subsequently, when receiving the information indicating that the handset conversion function is not included, handset 600 informs the user that the speed conversion function cannot be used (step S160).
[0065]
Specifically, when the control unit 100 of the slave unit 600 determines that the radio unit 140 has received a signal indicating that the master unit 500 does not have a speech speed conversion function from the master unit 500, the control unit 100 starts from the buzzer 190. A warning sound is output and the display unit 120 displays, for example, “the parent machine does not support the speech speed conversion function”.
[0066]
In step S160, the warning sound is output from the buzzer 190. However, for example, the buzzer 190 may output a message such as “the parent device does not support the speech speed conversion function”. . With this configuration, the user can more clearly understand why the desired function cannot be performed.
[0067]
In response to the function inquiry signal transmitted from the slave unit 600 to the master unit 500 in step S150, the master unit 500 stores the function information of the master unit 500 stored in the second storage unit 5 and the slave unit 600. Although it is configured to search whether the function information includes the speech speed conversion function, when the inquiry signal is transmitted from the slave unit 600 to the master unit 500, the master unit 500 side talks to the function information of the master unit 500. It is good also as a structure which searches whether the speed conversion function is included. In such a configuration, it is not necessary to transmit function information from the slave unit 600 to the master unit 500 when the slave unit is added.
[0068]
As described above, in the apparatus according to the present embodiment, first, function information is transmitted from the slave unit 600 to the master unit 500 when the slave unit is added, and the function information received from the slave unit 600 is stored in the second storage unit 5 on the master unit 500 side. To do. Subsequently, when an operation for executing a certain function is performed on the handset 600 side, the handset 600 inquires of the base unit 500 whether the base unit 500 supports the function, and the base unit 500 If it is determined that the function is not supported, a signal indicating that the function is not supported is transmitted to the slave unit 600, and the user is notified on the slave unit 600 side that the master unit does not support the function. .
[0069]
For this reason, the user on the handset 600 side can know why the function to be executed cannot be executed.
[0070]
In addition, since the user on the side of the handset 600 can know the reason why it cannot be executed, there is no misunderstanding that the communication device has failed.
[0071]
In this embodiment, when the slave unit is added, the function information is transmitted from the slave unit 600 to the master unit 500. However, when the wireless connection is made after the slave unit registration is completed, the slave unit 600 transmits to the master unit 500. It is good also as a structure which transmits function information.
[0072]
In addition, when the slave unit 600 receives function information from the master unit 500 when the slave unit is added or wirelessly connected after the slave unit is added, and the user of the slave unit 600 tries to perform a desired function, the slave unit 600 side If it is determined whether or not the parent device 500 can perform the function that the user of the child device 600 is to perform, and if it is determined that the child device 600 cannot be performed, the user of the child device 600 is notified of this. It is good also as a structure.
[0073]
Further, when an instruction to start a certain function is given on the parent device 500 side, it is determined whether or not the child device 600 supports the function, and the child device 600 corresponds to the function on the parent device 500 side. It is good also as a structure which alert | reports that it is not.
[0074]
Furthermore, in the present embodiment, the cordless telephone apparatus is implemented. However, the present invention can be similarly implemented as long as the communication apparatus includes the parent device 500 and the child device 600 such as a facsimile device in which the child device 600 is mounted.
[0075]
