Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a radio device that selects a desired one of a plurality of channels to make a call.

[Technical Background of the Invention and Related Points] Conventionally, this Yuzu radio device receives a calling number transmitted from any radio device, and determines that this calling number corresponds to the number registered in the own radio device. If it does, it is determined that the response is possible and the response operation is permitted. Also, when a response is possible in this way, the radio transmits a notification sound to notify the user of the response.

By the way, even if a notification material is emitted in this way, if a response operation is not performed for a predetermined period of time due to the absence of the operator, etc., in conventional radios, the writing standby state is returned after that. I was unable to respond to calls. That is,
Even if there was a call to one's own radio, it would simply be notified by a beep for a while.

In the past, even if a call came in when the operator was not present, the operator had no way of knowing what the call was. 11
In the MCA select call method (selective call type multi-channel access method), which transmits a call as a call and asks for a call to the desired party, if there is no response operation for a predetermined period of time even if there is a call, the call is not answered. It continues to emit a sound to notify the operator of the call, and displays the number of the wireless device on the calling side in the calling number on the display. I was able to know the wireless device on the calling side, and then perform a calling operation based on the displayed number.F, I was able to call the wireless device on the calling side.

However, with such radios, the call operation is performed by inputting the number displayed on the display by key operation, so this call operation is cumbersome and may lead to operational errors. 0 [Object of the Invention] The present invention has been made with attention to the above-mentioned circumstances, and even if a call is received while the user is absent, the system can easily connect to the wireless device of the calling party with a simple operation. The purpose of this invention is to provide a radio device that can make calls to people.

[Summary of the invention]

Therefore, the present invention registers the received calling number'&N as a number for making a call, performs a calling operation based on the number for making an incoming call in response to a predetermined incoming call operation, and makes a call. The above objective was achieved by making a call to the calling side's radio.

[Embodiments of the invention]

Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a communication system to which an embodiment of the present invention is applied. This pick-up 3 system is a system that adopts the MCA select call method, and has 16 channels in the 800M band (1 control channel, 15 communication channels).
The control station receives a call request from either the command station or the mobile station of each group A or H via the control channel, and sends a request for free status to the group A or B via the control channel. The number of command stations and mobile stations in groups A and B (both 2 stations) are assigned and the number of communication channels is set to 5 to perform communication via the communication channel. For example, as shown in group A in FIG. A calling number as shown in Figure 2 is transmitted through the channel.Then, all the command stations and mobile stations for the group capture the calling channel and send the called party number (the last four digits of the calling number). In this case, it is determined whether the mobile station a's number) is its own number or not.If mobile station a determines that it is its own number, it is allowed to make a call, so the communication between the command station and mobile station a is It is possible to make calls between

Now, one embodiment of the present invention applied to such a communication system will be described. FIG. 3 is a block diagram of an embodiment of the present invention, and FIG. 4 is an operation flowchart thereof. The receiving circuit 1 demodulates and amplifies the received data signal and converts it into a desired digital signal, and the self-number memory 2 stores its own number (a 4-digit number) that has been set and registered in advance by an operation means (not shown). ) is the only memory stored therein, and the matching circuit 3 compares the last four digits of the called number sent from the receiving circuit L with the number stored in the own number memory 2, and if they do not match. 5. The calling party number memory 4 stores the first four digits of the calling party number of the calling number sent from the receiving circuit 1, and also sends a start signal eY to the timer circuit 11. The switch 5 is a switch for transferring and storing the number stored in the calling party's number memory 4 to the called party's number memory 6, and when it is in the open state, it blinks on the display 9 for confirmation. A request signal f is sent to the driver circuit 8. The called party number memory 6 stores the switch data obtained by setting the setting switch 70 as the called party number, and also stores the switch data obtained by setting the setting switch 70 as the called party number.
It is a memory that stores the number transferred through the 8'A as the called party number, and stores only one number. When the calling operation is started by a predetermined operation of the calling operation switch 15, the number stored in the calling number forming circuit Lot-j is read out from the own number memory and the called party number memory according to an instruction from the transmitting circuit 16. This forms a calling number as shown in . Timer circuit 11
starts timing based on the start signal e from the verification circuit 3, and after a predetermined period of time has elapsed (here, to simplify the explanation, the predetermined period is defined as the time until the call is disconnected due to no response), the alarm circuit starts counting. 12Y is activated to generate an alarm sound from the speaker 13. Also, this timer circuit 11
When the call operation switch 15 and the stop switch 14 are operated, the time measurement contents are reset, and at this time, a control signal is sent to the alarm circuit 12 and the driver to stop the operation of the alarm circuit 12 and cause the display 9 to light up. times W & 8
Send to.

Next, the operation will be explained. When in standby mode, the control channel is necessarily captured, and when any station in the same group sends a call request signal to the control station, and the control station sends a signal requesting a predetermined call channel, Upon receiving this signal, not only the wireless device of this embodiment but also the stations (radio devices) within the same group capture the communication channel. When the calling number sent from the calling station is received, the calling number sent from the receiving circuit 1 and the number stored in the self-number memory 2 are compared W! r3 compares. Verification circuit 3 indicates that the comparison result does not match (call for other than own non-+W machine)
If so, it returns to the standby state, and if it is a match (a call to its own wireless device), it sends out a start signal ey and stores the calling party number in the received dispatch number in the calling 9I11 number memory 4. . Upon receiving this start signal C, the timer circuit 11 starts counting time. Also, the calling party number memory 4 stores and supplies the constant number to the driver circuit 8, which activates the driver circuit 8 and causes the display 9 to display the calling party number. At this time, the operator is nearby, and when he notices this and operates the call operation switch IEI', a transmission signal obtained from a microphone (not shown) is transmitted to the calling station. Therefore, a telephone call operation is performed from now on.

However, if the operator is away from the wireless device of this embodiment for a long time after the switch 5 is closed, the call operation switch, which is a response operation, may not be activated even after a predetermined period of time has elapsed. Since the operation 15 is not performed, the calling station 5 cancels the call and then the radio acquires the control channel again. By the way, when the switch 5 is in the closed state, the number stored in the calling party's number memory 4 is transferred and stored in the called party's number memory 6, and at the same time, the display 90 receives the call by sending out the flashing request signal f. The side number display will flash. Also, the alarm circuit 12 is activated in response to a time-over signal from the timer circuit 11, and the speaker 13 indicates that there is an incoming call? An alarm will sound to notify you.

After that, when the operator returns and notices the absent call from the blinking display on the alarm tuning fork and operates the call operation switch 15, the transmitting circuit 16 uses the calling number forming circuit 10 from the own number memory 2 and the called number memory 6. The storage number is expanded to form a calling number as shown in FIG. At the same time, as described above, the timer circuit 11 is reset, the alarm sound stops, and the blinking display on the display 9 is changed to a lighting display.

By the way, if you operate the stop switch 14Y without operating the call operation switch 15 because you have noticed that you are not home due to the alarm sound or flashing display, the timer circuit 11's time measurement is reset, the alarm sound stops, and the display The blinking display of 9 is canceled and the screen returns to the standby state.

As described above, according to this embodiment, by operating the switch 5 to close it, it is possible to easily respond to the latest call such as when the user is away from home, which is advantageous in terms of use.

5 In this embodiment, returning the switch 5 from the closed state to the open state is performed by the operation of 2 operation name '5. It may be possible to restore the state. In addition, in this embodiment, the called party number memory 6 has a switch,
The most recent number was stored by storing the received calling party number 'a'l@next' through Tube 5, but conversely, the called 0111 number memory 6 stored the first stored number. You can control it as much as you like.

FIG. 5 is a block diagram of another embodiment of the invention. The communication system to which this embodiment is applied is different from the above-mentioned one, and is one that is adopted as a personal radio system. This communication system has 80 channels (control channel Y) in the 900M band.
79 channel), the calling party's radio sets the group number (
A system that sends a 5-digit number) and a number specifying a call channel, and allows any radio set that has the same group number as the sent group number to communicate with the calling radio. It is. In other words, it is a system that allows communication to be made between groups when the set group numbers correspond to each other.

Now, the present embodiment applied to such a system will be described. The group number memory 52 is a memory in which group numbers are set and registered in advance, and here, as shown in FIG.
Two group numbers are registered for the U and “G2” groups;
An incoming call flag and a priority flag are set for each group number, respectively. The collation circuit 53 compares the group number sent from the receiving circuit 51 and the group number registered in the group number memory 52, and if they match, start the timer cycle w557) 4W No. e'a
? At the same time, it is sent to a signal flag setting circuit 54 indicating the group number of the incoming call. The flag setting circuit 54 receives the signal from the verification circuit 53 and sets the incoming call flag YrlJ of the group number where the incoming call occurred, and also sets the priority flag to "l". Note that this priority flag is set to "1" only for the group number that has received the most recent call, and is set to "0" for the previous group number.

The flag clearing switch 60 is a flag clearing switch that sets the incoming call flag and priority flag to "0". The timer circuit 57 starts measuring time based on the start signal e from the verification circuit 53, starts the arm alarm circuit Tf658, and outputs the speaker 59 until a predetermined period of time (for example, 10 seconds has elapsed).
When a predetermined period of time has elapsed, a flashing request signal f is sent to stop the operation of the alarm circuit 12 and to flash the group number display on the display 56. Further, this timer circuit 57 is operated by a call operation switch 61.
When the flag release switch 60 is operated, the time measurement contents are reset, and at this time, the operation of the alarm circuit 12 is stopped and the group number display on the display 560 is lit to display the alarm time W! The driver circuit 55 controls the r58 and the driver (g1wr55).The driver circuit 55 controls the display of the indicator 56, and causes the group number light to be displayed as well as the "GIJ" corresponding to the S= number being displayed.

This lights up the "G2" lamp.

Next, the operation will be explained with reference to FIG.

FIG. 7 is an operational flowchart of this embodiment.

First, when in the standby state, the control channel /I/ is captured and received by the group number receiving circuit 51 etc. which is sent from the radio on the calling side via this control channel. and,
If the matching circuit 53 determines that the received group number does not correspond to the group number registered in the JIF number number memory 52, it will remain in the standby state, and if it determines that it corresponds, it will receive the call along with the group number. A call channel is acquired based on the designated number of the channel and an incoming call operation is performed.

In this embodiment, both registered and fixed group numbers are detected and L
Comparison with the group number and comparison of one of the two registered group numbers with the detected group number can be performed, and this selection is designated by operating a mode designation key (not shown).

Here, the explanation will be made assuming that the mode is specified in which comparison with both group numbers can be performed. Receiving circuit 5
When a group number is obtained from the data signal received at step 1, the collation circuit 53 stores this group number in the register, and then compares the group number in this register with the group "ql" in the group number memory. Compare the numbers and if they match, send a match signal and start signal ev, if they don't match, send "G2"
It is compared with the # number of the group, and if it corresponds to the group number of this "G2" group, it is sent as a match signal and a start signal e'. When this matching signal is obtained, the flag setting circuit 54 sets the incoming call flag and priority flag (krlj) corresponding to the group number in the group number memory 52 determined to correspond, and sets the priority flag corresponding to other group numbers. Set the flag to "0". Further, when the timer circuit 57 receives the start signal e, it starts measuring time and sends an activation signal to the alarm circuit 58.

The alarm circuit 58 is activated by this activation signal, and the speaker 59 emits a ringtone. The generation of the incoming call tone continues until the timer circuit 57 measures a predetermined period of time or the call operation switch 61 or the flag release switch 60 is operated.

In the standby state, the driver circuit 55 stores the group number designated by the operation of the mode designation key described above (in the case of both designations, the group number of JG1jG1-) in the group number memory 52J.
This is read out and displayed on the display 56, and a lamp indicating which group the displayed group number corresponds to is lit. By the way, when there is an incoming call and each flag is set, the driver circuit 55 reads out the group number whose priority flag is set to "l" in the group number memory 52 and displays it accordingly. At this time, the operator is nearby and notices the call from the incoming call tone and switches the call operation switch 61'a? When operated, a transmission signal obtained from a microphone (not shown) is transmitted via the captured communication channel. Therefore, the call operation is performed thereafter.

However, if the operator is away from the wireless device of this embodiment for a long time, the call operation switch 61, which is a response operation, is not operated even after a predetermined period of time has elapsed. In the Nokuichi Sonal non-binding method, turn on the call operation switch,
The group number is always sent out as a data signal when it is OFF, and if the call operation switch is ON for about 15+ or more consecutive times, the group number is also sent out, so the call operation switch of one radio is set to ffr. If no operation is performed for a period of time, and the group number is not sent from the other stationary device for a predetermined period of time, it is determined that the call has ended and the device returns to the standby state. Therefore, in the above-mentioned case, since the call operation switch 61 is not operated, there is no longer a call from the radio on the calling side, and it is determined that the call has ended, and the call returns to the standby state. At this time, the timer circuit 57 continues to measure time due to no operation of the call operation switch 61, and when a predetermined period of time has elapsed, the alarm time v!
I! It prohibits the sending of the activation signal to r58 and sends out the blinking request signal fi. In response to this signal f, the group number displayed on the display 56 flashes and the generation of the ring tone stops.

After that, when the operator notices that the call is absent from the blinking display and operates the call operation switch 15Y, the transmission circuit 62
reads out the group number whose succeeding flag in the group number memory 52 is set to Ill and performs a calling operation, and this priority flag is set to "0". Except for this, if the incoming call flag for the other group number is set to "l", its priority flag is set to "l".

Further, the timer circuit 57 is reset and the sending of the blinking request signal f is stopped. The driver (b) path 55 receives this signal f.
When transmission of the group number is stopped, the blinking display is stopped and the display is turned on, but when the priority flag corresponding to the other group number is set to "1", the blinking display is continued. When it is determined that the current filling operation has been completed, the driver circuit 55 then displays the other group number blinking.
The blinking display continues until a call operation (operation of the call operation switch 61) for this second group number is performed. When a call operation for this second group number is performed, the priority flag of that # number is set to "0", and the driver time %55 is lit and displayed. That is, the driver circuit 55 performs a blinking display for each group number whose priority flag is set to "1".

By the way, if you notice from the flashing display that Kanohi is away and operate the flag release switch 60 without operating the call operation switch 15, all the valley flags in the group number memory 52 are set to "0" and the timer circuit 57 Flashing request value number f from
transmission is also stopped, the blinking display on the display 56 is canceled, and the normal standby state is restored.

In this way, according to this embodiment, unlike the above-mentioned embodiments, it is possible to easily respond to the latest call such as when someone is away, without having to install and operate any special switch, which is more useful in use. It is.

In this embodiment, two registered group numbers are compared, but only one of the 10,000 group numbers may be compared. In addition, in this embodiment, when there is an incoming call for both of the two registered group numbers, the two group numbers are displayed blinking continuously, but during the call operation for the first n number, The blinking display may be stopped, and the second group number may be displayed blinking at the L stage after the call associated with the call is completed. Further, in this embodiment, only the group number is displayed blinking, but the "G1" and "G2" lamps may also be displayed blinking.

〔Effect of the invention〕

As explained above, according to the present invention, even if a call is received when the operator is absent, such as when the operator is away, the operator can easily confirm the fact and can easily call the operator with a simple operation. You can call the calling party's wireless device. Therefore, it is convenient to use, and the unpleasant trapping of a communication channel due to no response is reduced.
