Abstract

PURPOSE:To reduce the time for establishing a talking channel between a master set and a slave set by establishing the talking channel when a discrimination section provided to the slave set discriminates a registered idle talking channel and making talking between the master set and the slave set through the talking channel. CONSTITUTION:In the case of establishing a talking channel, names of plural idle talking channels registered in a master set 1 are sent to a slave set 30 and a discrimination section of a CPU 40 in the slave set 30 discriminates the plural talking channels to be idle, then the talking channel is established. Thus, the confirmation and discrimination of the idle state of registered plural idle talking channels are implemented simultaneously. Thus, the talking channel is established in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cordless telephone device that establishes a communication channel between a base unit and a slave unit connected via a wireless line.

[Prior Art] When establishing a call channel between a base unit and a handset in a conventional cordless telephone device of this type, first, one call channel that is registered in the base unit and that the base unit determines to be free is established. is sent to the slave device. Then, when the slave unit receives this one call channel and determines that this call channel is free, the base unit and slave M! A communication channel between the base unit and the slave unit is established, and communication between the base unit and the slave unit is performed via this communication channel.

Additionally, if the handset determines that one received call channel is not free, the handset notifies the base unit of this fact, and as a result, the base unit determines whether the next registered call channel is free or not. One communication channel that is determined to be in a state is transmitted to the handset, and the handset is asked to determine whether or not this communication channel is in an idle state.

[Problems to be Solved by the Invention] In the above-described conventional cordless telephone device, if a call channel that is registered in the base unit and determined to be free by the base unit is not available in the slave unit, There was a problem in that it took time to establish a communication channel between the device and the handset.

[Means for Solving the Problems] In order to solve such problems, the cordless telephone device according to the present invention uses a plurality of free call channels provided in the base unit and registered in advance when starting a call with the handset. home,
It is equipped with a transmitter that transmits a predetermined number of free call channels, and a judgment unit that is provided in the handset and determines whether or not the free call channels transmitted from the transmitter are in the free state.

In addition, there is a control signal transmitter provided in the handset that transmits a control signal when the judgment section determines that all the received call channels are not free, and a control signal transmitter provided in the base device that transmits a control signal when all received call channels are determined to be free based on the reception of the control signal. This device includes a registration determining unit that determines whether a call channel is registered or not, and a control unit that is provided in the base unit and causes a transmitting unit to transmit the vacant call channel determined by the registration determining unit.

Additionally, an alarm unit that issues an alarm when the registration determination unit determines that an empty call channel is not registered is installed.
It is prepared for the occasion.

Further, the handset is equipped with an alarm unit that generates an alarm when an empty call channel is not received from the base unit within a certain period of time after the control signal is transmitted.

[Function] When the registered free call channel is determined to be free by the determining unit provided in the handset, the call channel is established, and a call between the base unit and the handset is performed via this call channel. be exposed.

Also, if the above judgment unit does not judge that there is a vacancy,!
A call is made between the base unit and the handset via the free call channel determined by the registration determination unit provided in the R machine.

Also, if no free call channel is registered,
An alarm is issued.

Further, if an idle communication channel cannot be received within a certain period of time after the control signal is transmitted, an alarm is issued.

[Example] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a cordless telephone device according to the present invention.

In the figure, 1 is tRR, and 30 is a slave device.

The IIR machine 1 is configured as follows.

That is, 2 is a communication circuit, 3 and 8 are diode bridges, 4 is a transistor, 7 is a wireless transmitting/receiving unit for communicating with the child 11130, 9 is an incoming call detection circuit, and 10 is a device that communicates with the child 30 via data transmission. 12 is a power supply circuit, 13 is a battery 14, L7 and 22 are diodes, 1
5 is a voltage detection circuit, 16 is a current detection circuit, 19 is a dialer that sends a dial signal to the central office line, 20 is a ringer that outputs a ringtone, an alarm sound, etc., and 21 is an antenna.

Further, the handset 30 is configured as follows.

That is, 31 is a wireless transmitter/receiver unit that communicates with base unit 1;
2 is the battery, 35.37 is the handset, 40 is the parent at
41 is a voltage detection circuit, 42 and 43 are diodes, and 44 is the parent 1! ! A key circuit includes a call button for calling 1 and a call button for making a telephone call, 45 is a ringer that outputs a ringtone, an alarm sound, etc., and 46 is an antenna.

Then, when the base unit 1 is off-hook to call the slave unit 30 and a call button (not shown) provided in the base unit 1 is pressed, the CPU10 detects this and
Search for free call channels registered in the memory of the handset 3, and transfer the searched free call channels to handset 3.
Send to 0. And child 1! ! In step 30, it is detected whether or not these free call channels are in a free state, and if they are in a free state, it means that the call channel has been established, and then an extension call process is performed and the handset 3
When a response of 0 is detected, an extension call is made with the handset 30 via one of these free call channels.

Next, the second section regarding the operation of the cordless telephone device of the present invention will be explained.
This will be explained based on the flowcharts shown in FIGS.

First, the operation of CPULO in the parent at will be explained based on the flowchart of FIG.

Free CH search in step 50, that is, CP
A memory (not shown) built in U10 is searched to detect a previously registered free call channel, and then in step 51 it is determined whether a free call channel is registered. If this is not registered, the process returns to step 50, or if an empty call channel is registered, the process returns to step 51 (and the process determines whether activation request data from the slave device is received (to be described later). Step 52).If the step 52 is '7N J, it is determined in step 53 whether the call button to call the machine 30 has been pressed, and if this is "N", the step 750 is pressed. Return to

Further, upon receiving the startup request data, in step 52 "YJ
If the call button is pressed and the answer is "Y" in step 53, a timer is started in step 54, and it is determined whether there are two or more registered free call channels (step 55).

If two or more free call channels are registered, the result is "Y" in step 55, and the result is "D" in step 56.
Set the data indicating the first free call channel in the ATAL area, and then at step 57 select D A ′.
Set the data indicating the second free call channel in the FA 2 area, and in Step 1 Pro 0, enter the second DAT.
AI, go to area 2.

Send the recorded data to the fw 1130 9 Also, if two or more free communication channels are not registered, the result in step 55 is 'N'; in this case, the result in step 58 is
In step 5, send data indicating a free call channel to the DATAI area, and in step 5, DA'FA2
Separate the NG data indicating that there is no second free call channel in the area of F! Send to lA30.

In this way, when these data are sent to the f unit 3o, the slave unit 30 detects whether or not these call channels that were registered as free call channels are really free, and transmits the data resulting from this detection to the base unit. It will be returned to 1.

That is, if the OK data of DATAL transmitted in step 60 can be received, "Y" is returned in Step 1, and in this case, the free call channel set in DATAI is also used as a free call channel on the handset 30 side. Since the decision has been made, a call channel is established,
In step 62, the transmission/reception channel is switched to the idle communication channel set in DATA1, and in step 64, it is determined whether the communication channel has been established by receiving activation request data from handset 30. If this is "Y", this means that the slave Ia 30 calls the base unit 1, and in step 65, the extension call process from the slave unit is performed. If r N is determined in step 64, the base unit 1 presses the call button to call the slave unit 30, so step 6
Step 6 performs extension call processing from the base unit.

Also, in step 60, child 1i! DAT sent to 130
If the OK data of AI cannot be received, the result is "N" in step 61, and then the OK data of DATA2 is determined in step 67.
Determine whether data has been received, and if it can be received, DATA2
The empty call channel that was set and sorted is child! Since the communication channel is determined to be free on the 30 side as well, the communication channel is established.In other words, in step 63, the transmission/reception channel is switched to the communication channel set in this DATA2, and the processing from step 64 described above is performed. .

In addition, if the OK data of DATAI cannot be received in step 67, the result is "N", and in this case, the process moves to step 70 to determine whether the timer has timed up. Based on the reception of the NG data (control signal), it is determined whether the free call channel registered in the memory in step 72 still exists (registration judgment section), that is, the judgment is made whether there are three or more free call channels. If this exists and the determination is "Y", the process returns to step 55 and data indicating an empty call channel different from the previously transmitted data is sent to the handset 3.
In addition, if the timer times out in step 170, and if the timer times out in step 72,
If at least one free call channel is not registered, error processing is performed in step 73, such as driving the ringer 20 to generate an alarm from the speaker.

Next, the operation of the CPU 40 in the child 1!30 will be explained based on the flowchart of FIG.

In step 80, pressing the call button to call Hill is fJIlt7rL, and if this is "NJ, Stella 781 Then, if this cannot be received, proceed to step 8.
It returns to 0, but when it is received and becomes "Y", a timer is started in step 82, and the processing from step 86 onwards is executed.

In addition, if the call button is pressed, step 80 shows "
Y” and starts the timer in step 83.
In step 84, activation request data accompanying the press of the call button is transmitted to base unit 1, and in step 85, data set in area DATA1.2 accompanying this activation request data, that is, data indicating an empty call channel, is received by Mfil. Then, the process moves to step 86.

Then, in step 86, the reception is set to DATA 1.
Switching to the sorted free call channel, a detection judgment is made in step 87 as to whether or not the second free call channel is free, and if it is determined to be "Y", it means that the first call channel has been established. So, Step 7 is 88.”
The MFI 41 returns OK data to the base unit 1 indicating that the data indicating the free call channel set in this DA'rA1 is in the free state, and in step 89, the subsequent transmission channel is set to the free call channel set in this DATAI. Switch to the call channel. Then, in step 90, the handset 30 sends activation request data to the base unit 1, thereby determining whether or not a communication channel has been established.
If this is [YJ, handset 3° presses the call button to call base unit 1, and in step 91, extension calling processing from the handset is performed. Further, if it is determined "N" in step 90, the base unit 1 presses the call button to call the slave unit 30, and in step 92, an extension calling process from the base unit is performed.

Furthermore, if it is determined that the data indicating an idle communication channel set in DATAI is not in an idle state, the result is "rN" in step 87, and the data set in DATA2 is determined to be NG data. When , it becomes r YJ in step 93, and in these cases,
In step 94, NG data is transmitted to 11N11, and since the communication channel is not available, in step 95 reception is switched to the control channel and subsequent data reception is performed.

Then, in step 96, the time-up of the timer is determined, and if it is "N", next, the data of the next free call channel registered in mll'll as a result of sending the NG data to the parent Ial is A reception judgment is made in step 97, and if it is "N", step 1 block 96 is made.
However, if the answer is ``Y'', the process returns to step 86 and the reception is switched again to the idle communication channel set in DATAI, and the idle state of this communication channel is detected and determined. Further, if the timer expires in step 96 and it is determined as ``Y'', then in step 98 the ringer 45 is activated to perform error processing such as causing an alarm to be output from the speaker.

Also, if it is determined in step 93 that the data set in DATA2 is not NG data, data indicating an empty call channel is set in DATA2, and therefore, in step 100, the data set in DATA2 is not rejected. In step 101, the idle state of this communication channel is detected and determined. And this DATA2
If it is determined that the communication channel set to is also not vacant, NG data is transmitted to base unit 1 in step 94, and the processes from step 95 onwards are executed. Also,
If the data indicating the free call channel set in DATA2 is in the free state, "Y" is determined in step 101, and then in step 102, the data indicating the free call channel set in DATA2 is in the free state. After sending back OK data to the main unit 1 and switching the subsequent transmission channel to the free call channel assigned to this DATA 2 in step 103, the Stellaf 90
Execute the following processing.

Note that the establishment of a call channel in this embodiment has been described as an example in which an extension is called by pressing the call button. It may be applied to the case where a call is made to a central office line by pressing the call button No. 30, and
It may also be applied when responding to an incoming call from a central office line.

[Effect of the Invention 1] As is clear from the above explanation, when establishing a call channel, the cordless telephone device according to the present invention transmits a plurality of free call channels registered in the base unit to the slave unit, If these multiple free call channels are connected to one
fII! ! Since the call channel is established when the i section determines that the call channel is free, it can be done at once with the check Wfr of the free status of multiple registered free call channels, and the call can be made in a short time. This has the effect of establishing a channel.

Additionally, an alert will be issued if no free call channel is registered or if a free call channel cannot be received within a certain period of time after the control signal is sent.
This has the effect of notifying the operator that the communication channel is not established.
