2. Description of the Related Art A cordless button telephone device is a main device.
(Key phone main unit) and a plurality of cordless telephones connected thereto. Further, a general telephone can be connected to the main unit.

[0003] The main unit and the base unit of each cordless telephone are connected by wire, and the base unit and the slave unit are connected by a wireless line during communication. A plurality of master units arranged in the same area form a master unit group, and the slave units can wirelessly connect to any master unit in the group.

When the main unit of the cordless button telephone apparatus detects an incoming call from the office line, a signal of a simultaneous incoming call is transmitted from the main unit to each cordless telephone. The base unit of the cordless telephone that has received the signal transmits an incoming call request signal to the standby unit using the `` control channel '' commonly used in the entire system, and waits for the response of the unit, The communication channel is shifted to the “communication channel” specified by the master unit, and a sounding instruction signal is sent to the slave unit using this communication channel to start the sounding of the slave unit. When the user picks up one of the handsets that ring simultaneously and operates a response button, a call path is set between the handset and the office line, and the other handsets return to a standby state.

[0005]

In the conventional simultaneous incoming how in THE INVENTION Problems to be Solved] cordless key telephone system, are associated with slave unit one by one for each one of the plurality of base unit, the respective master unit and the slave unit A communication channel was set in the interim, and each handset was sounded. Therefore, when the number of master units is smaller than the number of slave units, there are slave units that cannot sound.

Further, in the conventional simultaneous incoming how, when the master unit outputs a call request signal at the same time towards the handset, radio control channel collide, because the mutual squashing of the parent device control channel It is necessary to adjust so that radio waves are output at different timings. When the radio wave output timing of each master unit is shifted by this adjustment, in proportion to the number of master units,
It has the disadvantage that it takes time for the last handset to ring.

[0007] The present invention is intended to remedy these drawbacks that the conventional simultaneous incoming how is provided to a plurality of slave unit with a master unit less number than the slave unit, a short time is an object of the present invention to provide a simultaneous incoming how cordless key telephone system that can be carried out all at once coming into.

[0009]

[0010]

One master unit performs an operation of switching a reception channel to a communication channel or a control channel in a time sharing manner.

[0012] In addition, for a slave unit that cannot receive a communication channel designation signal transmitted by one master unit, another master unit uses a control channel to specify a communication channel designation signal and information on simultaneous ringing. And an operation in which the child device that has received the notification participates in the simultaneous ringing.

[0013]

Therefore, a plurality of slave units can be sounded simultaneously by the operation of one master unit.

[0014] The communication channel is captured between one master unit and one slave unit, and the other slave units maintain only the state in which the communication channel can be received without capturing the communication channel. I have.

When another slave responds to the simultaneous ringing, a response signal is transmitted from the slave using a control channel. The response signal is received by the master unit when the one master unit switches the reception channel to the communication channel or the control channel in a time-division manner, and
Otherwise, it is received by another master and causes the one master to perform an operation of switching the communication destination of the acquired call channel to the slave.

In this case, transmission and reception of signals with the RF unit 34, transmission of signals to output display devices such as the display lamps 4 and 5, the speaker 6 and the LCD 7, and reception of input signals from the operation buttons 8 and 9 are performed. The storage unit 33 stores position registration information, an identification code, and the like. The button detection unit 35 checks whether or not the operation buttons 8 and 9 have been pressed, and determines whether the operation buttons 8 and 9 have been pressed. Is performed. The control unit 32 edits a command to the base unit 2 based on the signal of the button detection unit 35 and controls the operation of each unit of the slave unit 3 including the output display device and the like.

Next, the procedure for performing simultaneous paging to a plurality of slave unit by simultaneous incoming how the present invention will be described with reference to a flowchart shown in FIG.

[0021] In simultaneous incoming how the present invention, a plurality of slave units are designated sounding simultaneously, the acquisition of the traffic channel,
This communication is performed only between one master unit A and one slave unit a, and a communication path between one slave unit and the office line responding to the simultaneous ringing is set using this communication channel. .

Step 1: When an incoming call from the office line is detected, the system control unit 12 of the main device 1 outputs a command for a simultaneous incoming call.

Step 2: the terminal control unit 14 of the main apparatus 1 which has received the command prepares a list in which the mobile units 3 to be sounded are classified based on the position registration information stored in the storage unit 13; 3; The parent device groups of the child devices on this list
One master device A to be formed is selected, and an instruction for an incoming call request is sent to the master device A together with this list.

Step 4: Receiving the instruction, master A selects one slave a from the list, and step 5: RF unit 24
Then, a simultaneous incoming signal is transmitted together with the identification code of the selected slave unit a using the control channel, and a response is instructed to the selected slave unit a.

Step 6: If the selected slave unit a does not respond within a predetermined time, the process returns to step 4 to select another slave unit and repeat the subsequent operations.

Step 7: In Step 6, when the selected slave unit a responds using the control channel, the master unit A designates a communication channel to the selected slave unit a using the control channel. A designated signal is sent, and the channel is shifted to the designated communication channel, and an instruction is made to return a response through the communication channel. At the same time, a communication channel designation signal is also sent to the other child devices registered in the parent device group to which the parent device A belongs, and the reception channel of the RF unit 34 of each child device is designated. To switch to.

Step 8: If there is no response from the selected slave unit a via the communication channel, the call is terminated. If there is a response, step 9: the master unit A identifies the listed slave units to be sounded with respect to the selected slave unit a and each of the registered slave units by using the communication channel. Sends chord and ringing instructions.

Step 10: Each slave unit corresponding to the identification code starts step 11;

Step 12: In step 10, the child device whose identification code does not match returns to the standby state and does not ring.

According to the above procedure, by using one master unit A, a plurality of slave units can be sounded simultaneously. At this time, the communication channel is captured between the master A and the selected slave a.

In response to the simultaneous ringing, the user picks up the slave unit a selected and operates the operation button 9 to respond to the simultaneous incoming call, and the communication channel captured with the master unit A remains unchanged. Used to set the call path.

Also, the user picks up the other handset b and
When the operation button 9 is operated and the incoming call is answered,
The button detection unit 35 detects this and sends a signal to the control unit 32.
The control unit 32 transmits the simultaneous incoming response signal via the RF unit 34.
From the antenna of slave unit b, send it to master unit B other than master unit A.
I believe. This transmission is performed using a control channel.
You. The main unit B is mainly equipped with the fact that the sub unit b has answered the paging call.
To the main unit 1 and the main unit 1forHas captured
Switch the communication partner of the communication channel from slave unit a to slave unit b
Master A sends the slave through the communication channel.
By sending out the identification code given to b,
Switching the communication partner of the communication channel from the slave unit a to the slave unit b
You. In this way, the communication route between the slave unit b and the office line is set.
It is.

Also, in this case, if the base unit A is configured to switch the reception channel of the RF unit 24 between the control channel and the communication channel in a time-division manner, the simultaneous incoming response by the slave unit b using the control channel is achieved. Can be received by the master unit A. At this time, the master unit B is not required.

In the above description, information relating to simultaneous ringing including an identification code of a child unit to be sounded and a ringing instruction is transmitted to each child unit whose location is registered, using a communication channel. (Step 9), the information on the simultaneous ringing is simultaneously transmitted to the slave unit a selected from the master unit A using the control channel when the communication channel designation signal is sent (step 7). May be.

[0035] in the simultaneous incoming how in this way, the present invention,
Until the simultaneous ringing, the transmission of the signal by the wireless line is 1
Since the control is performed by one master unit and one slave unit, a situation in which control channels collide or crush each other does not occur. Therefore, as in the prior art how, because it is not necessary to adjust the operating time of the control channel, it is possible to perform simultaneous incoming in a short time.

If there is a handset that cannot join the simultaneous call due to communication with another base unit, after the handset returns to the standby state, a call from the specified base unit is made by another base unit. The channel information and the information on the ringing are notified using the control channel, so that the slave unit can be added to the simultaneous incoming call later.

[0037]

As apparent from the above description of the embodiments according to the present invention, according to the unison ring how the present invention can perform simultaneous incoming with base unit less number than the slave unit.

[0038] In addition, the time required for the simultaneous incoming, in the way of the present invention, is about 2.1 seconds, this time, a single parent
Use the control channel from the
This method of transmitting the designated signal does not change even if the number of slave units increases. In contrast, in the conventional how, when the number of the slave unit and n stand requires 2 seconds × n times. Therefore, in the simultaneous incoming how the present invention, as compared with the conventional how, it is possible to perform simultaneous incoming in a very short time.
