Abstract

PURPOSE: To obtain a telephone system in which any telephone sets other than a priority ringing telephone set can reply a call quickly. CONSTITUTION: When an incoming call detects an incoming call detection section 115 while the priority mode is set, a microcomputer 106 allows a telephone set with priority ringing set by key operation of a key entry section 111 among a master set 1 and plural slave sets to start ringing in a large tone volume and allows the other telephone sets to start ringing in a small tone volume. When the telephone set starting ringing in the large tone volume does not reply a call for a prescribed time, the microcomputer 106 controls all the telephone sets to start ringing in a large tone volume. In the case of an incoming call through an external line, since the telephone sets not being the priority ringing telephone set in a large tone volume start ringing in a small tone volume at first, each possessor recognizes that its own telephone set is not the priority ringing telephone set and the arrival of an incoming call through an external line. Thus, the user can immediately reply a call when all the telephone sets start ringing in a large tone volume.

When the call key 209 of the cordless handset that is ringing at a high volume is pressed, a response signal is sent to the parent device 1 and the connection switch 101b (see FIG. 3) of the line controller 101 is turned on. And the line is connected, so that the mobile phone is in a call state.

When making a call to the other party from any of the slave units 2 _-1 to 2 _-N , the following communication operation is performed, for example. First, the call key 209 of a predetermined slave unit is pressed, and a signal "transmit" and an ID code are sent to the master unit 1 side through the control channel. Upon receiving this, the base unit 1 confirms that it is the ID code of its own handset, searches for a vacant channel for communication, and notifies the handset. The slave unit detects whether or not the call channel is free, and when it is free, sends a confirmation signal to the base unit 1 through the call channel.

Next, in the base unit 1, the connection switch 101b of the line control unit 101 is turned on to connect to the exchange, and when the connection is established, the dial tone signal sent from the exchange is transmitted through the communication channel to the handset. Send to the side.
The following is similar to the case of using the base unit 1, the key input unit 2
A call operation can be performed by using 08 to input the telephone number of the other party.

[0038] While the communication of 2 _-1 to 2 _-N base unit 1 and handset as described above are performed using a control channel or a predetermined communication channel, the master unit 1 and handset 2 _-1 to 2 _{- N} microcomputer 10
Reference numerals 6 and 206 control so as to switch the transmission / reception frequency of the radio units 107 and 202 according to the control channel and the communication channel used.

In this example, when the incoming call detection unit 115 detects an incoming call from an outside line, the microcomputer 106 of the master unit 1 operates as shown in FIG.
The ringing operation of the master unit 1 and the slave units 2 _-1 to 2 _-N is controlled according to the flowchart of FIG.

First, when there is an incoming call from an outside line, step ST
In step 21, it is determined whether the priority ringing mode is set or not by referring to the mode setting information in the setting state storage unit 112. When in the priority ringing mode, the priority ringing telephone set in step ST22 starts the ringing operation at a high volume and the other telephones at a low volume, and the ringing operation is started at step S22.
The counting operation of the timer 119 is started at T23. Then, in step ST24, it is determined whether or not there is a response from the priority ringing telephone that is ringing at a high volume, in step ST25 it is determined whether or not the calling side has disconnected the line, and in step ST26, the timer 119 By referring to the count output, it is determined whether or not a predetermined time, for example, 30 seconds has elapsed. If there is a response in step ST24 or the line is disconnected in step ST25, step ST
At 27, the ringing operation is ended.

When the predetermined time has elapsed in step ST26, the master unit 1 and the slave units 2 _-1 to 2 _-N are searched in step ST28.
All the telephones are controlled so as to ring at a high volume, and it is determined in step ST29 whether or not there is a response in the ringing telephones. In step ST30, it is determined whether or not the calling side disconnects the line. judge. Step ST29
If there is a response in step ST30 or the line is disconnected in step ST30, the ringing operation is ended in step ST27. When the priority ringing mode is not set in step ST21, the process proceeds to step ST28 and all the telephones of the master unit 1 and the slave units 2 _-1 to 2 _-N start ringing operation at a high volume, and the same as the above. Process.

Although not described above, the predetermined time in step ST26 of the flowchart of FIG.
It may be configured so that it can be arbitrarily set by a key operation of 11 (see FIG. 2).

As described above, in this example, when an outside line arrives in the priority ringing mode, the priority ringing telephone first starts the ringing operation at a high volume, and the other telephones start the ringing operation at a low volume. Therefore, the owner of the other phone can know that his or her own phone is not the priority ringing phone and can know the outside line call.
Therefore, there is no response from the priority ringing telephone within a predetermined time, and when all the telephones start ringing at a high volume, they can immediately respond. As a result, a response can be made quickly by a telephone other than the preset priority ringing telephone, and the caller can be prevented from waiting for a long time.

Next, a second embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the telephone device of this example is also composed of one master unit 1 and N slave units 2 _-1 to 2 _-N . In this example, the priority ringing telephone is set based on the designation of the calling side priority ringing telephone. The cordless handsets 2 _{-1 to} 2- _N are configured in the same manner as the example of FIG. 4 described above.
FIG. 6 shows a configuration example of the base unit 1. 6, parts corresponding to those in FIG. 2 are designated by the same reference numerals, and detailed description thereof will be omitted.

+1) etc. are stored. In this example, the terminal number (extension number) of the master unit 1 is preset to "1", and the terminal numbers of the slave units 2 _-1 to 2- _N are preset to "2" to "N + 1", respectively.

Further, the counter 11 is provided in the microcomputer 106A.
8 are connected. The counter 118 is for counting the number of calls. Here, the number of times of calling means the number of times that a 16 Hz calling signal is sent from the exchange. During the period when the call signal is sent from the exchange, the calling side sends 400Hz for 16H from the exchange.
A z-modulated ringback tone signal is provided. The counting operation of the counter 118 is performed using the incoming call detection signal output from the incoming call detection unit 115. The parent device 1 of the present example is configured as described above, and the others are configured similarly to the example of FIG.

In this example, when the incoming call detection unit 115 detects an incoming call from an outside line, the microcomputer 106A of the master unit 1 follows the flowchart of FIG. 7 and the master unit 1 and the slave units 2 _-1 to 2 _-N.

First, when there is an incoming call, step ST41
Then, it is determined whether or not the priority ringing mode is set by referring to the mode setting information of the setting state storage unit 112A. If it is the priority ringing mode, the counter 118 is operated in step ST42.
The counting operation of the number of times of calling is started at this time, but at this point, the terminals of the master unit 1 and the slave units 2 _-1 to 2 _-N are not allowed to perform the ringing operation. Next, in step ST43, the number of calling times counted by the counter 118 is (N + 1)
The line disconnection detection unit 1 determines whether or not the line is disconnected on the calling side.
It is judged by the detection signal from 17.

In step ST43, the number of calls is (N +
If the calling side disconnects within 1), step ST
At 44, the counting operation of the timer 119 is started, and at step ST45, it is determined whether or not there is a re-incoming call within a predetermined time, for example, within 1 minute, by referring to the count output of the timer 119. When the incoming call is received again within a predetermined time in step ST45, the count value of the counter 118 when the line is disconnected in step ST46, that is, the line is disconnected on the calling side after the first incoming call is made. The telephone having the same terminal number as the number of calls M up to is started with a high volume and the other telephones are started with a low volume, and the counting operation of the timer 119 is started in step ST47.

Then, in step ST48, it is determined whether or not there is a response from the priority ringing telephone that is ringing at a high volume, in step ST49 it is determined whether or not the calling side has disconnected the line, and in step ST50. By referring to the count output of the timer 119, it is determined whether or not a predetermined time, for example, 30 seconds has elapsed. When there is a response in step ST48 or the line is disconnected in step ST49, the ringing operation is ended in step ST51.

When the predetermined time has elapsed in step ST50, the master unit 1 and the slave units 2 _-1 to 2 _-N are searched in step ST52.
In step ST53, it is determined whether or not there is a response in the ringing telephones, and in step ST54, it is determined whether or not the calling side has disconnected the line. When there is a response in step ST53 or when the line is disconnected in step ST54, the ringing operation is ended in step ST51.

If there is no incoming call again within a predetermined time in step ST45, the flow of the ringing operation is immediately terminated, and the standby state for the outside line incoming in the priority ringing mode is again established. Also, when not set to priority ringing mode in step ST41, or number of calls in the step ST43 is (N + 1) within when not line disconnection at the calling side, the master unit 1 and slave unit proceeds to step ST52 2 _{- If} all ₁ ~ 2 _-N phones are controlled to ring at a high volume and there is a response or if the caller disconnects the line,
The ringing operation is ended in step ST51. Here, if the calling side does not disconnect the line within the number of calls (N + 1) in step ST43, it can be determined that the calling side does not consider the designation of the priority ringing telephone set, so that the ringing operation is performed on all the telephone sets as described above. Is executed.

It should be noted that, instead of the above description, the predetermined time in step ST45 or step ST50 of the flowchart of FIG. 7 may be arbitrarily set by the key operation of the key input unit 111A (see FIG. 6).

In this example, when an incoming call arrives in the priority ringing mode, the counter 118 counts the number of calls. When the calling side disconnects the line within the count value of the number of calls (N + 1), if a redial call is detected within a predetermined time, the line from the first incoming call to the line disconnection is detected. Only the telephone having the same terminal number as the number M of calls is controlled to ring at a high volume. Therefore, the calling side can arbitrarily specify the priority ringing telephone by referring to the ring back tone and adjusting the number of calls until the line is disconnected.

In this example, when an outside line is received in the priority ringing mode, the priority ringing telephone specified by the calling side starts ringing at a high volume, while the other telephones ring at a low volume. Start. Therefore, the owners of other telephones can know that their own telephone is not the priority ringing telephone and can know the outside line incoming. Therefore, there is no response from the priority ringing telephone within a predetermined time and all the telephones have a loud volume. You can respond immediately when you start ringing with. As a result, similarly to the first embodiment, it is possible to quickly make a response by a telephone other than the preset priority ringing telephone, and prevent the caller from waiting for a long time.

In the above-described embodiment, when there is an incoming call to the outside line, the priority ringing telephone sets the ringing volume at a high volume and the other telephones ringing at a low volume level. In this state, the priority ringing telephone set can answer only. As mentioned, all telephones may be allowed to respond. Further, in the above-described embodiment, when there is an outside line incoming in the priority ringing mode,
First, the priority ringing telephone is set to perform a ringing operation at a high volume, and the other phones are set to perform a ringing operation at a low volume. However, whether the priority ringing telephone is a priority ringing telephone or not is not a volume level, but other modes such as tone color. You may distinguish so that it can distinguish.

[0057]

According to the present invention, when an external line arrives in the priority ringing mode, the priority ringing telephone set on the receiving side or the calling side starts the ringing operation in the first mode, and Since the telephone of No. 1 starts the ringing operation in the second mode, the owners of the other telephones can know that their own telephone is not the priority ringing telephone and can know the outside line incoming, and therefore within the predetermined time. There is no response from the priority ringing telephone, and all the telephones can respond immediately when they start ringing in the first manner. As a result, a response can be made quickly by a telephone other than the preset priority ringing telephone, and the caller can be prevented from waiting for a long time.
