Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to personal radio equipment, and in particular, to group numbers other than the standby designated group number among the group numbers stored in the memory and the group number included in the received signal. The present invention relates to a personal wireless device that can promptly communicate with the other party who is transmitting the group number when the group numbers match.

<Prior art> A personal radio device stores a plurality of group numbers in its built-in memory (not limited to one), and sets two of the group numbers as standby designated group numbers; When the designated standby group number and the group number included in the received signal match in the standby state, the press talk button can be pressed to communicate with the other party. In addition, when the personal radio is in monitor mode, if it can receive a signal on a predetermined channel and the group number included in the signal matches the designated standby group number, it can receive the signal of the other party communicating on the channel. It is now possible to interrupt and communicate with each other. Furthermore,
In addition to the above-mentioned dual standby mode, the personal radio set the standby designated group number to "00000" so that it can communicate with the other party when there is an "all zero" general call (CQ standby mode). ).

Furthermore, it is prohibited by industry association standards to stand by and communicate with the other party by any method other than the above-mentioned dual standby and CQ standby.

<Disadvantages of the prior art> As mentioned above, since conventional personal radios stand by with a maximum of two group numbers, even if other group numbers preset in the memory can be used when calling, they cannot be used when in standby. It was not available. This is extremely inconvenient when communicating frequently with three or more people.

<Object of the invention> The object of the invention is to achieve the following without compromising the standards of industry associations:
When the group number included in the received signal matches the group number other than the group number specified for standby among the group numbers preset in memory (when called in a mode other than dual standby), you can immediately communicate with the other party. The purpose of the present invention is to provide a personal wireless device with a high level of functionality.

Another object of the present invention is to provide a personal radio that indicates that it is being called outside of dual standby.

Still another object of the present invention is to provide a personal radio device which, when being called in a mode other than dual standby, can set the group number of the incoming call to the designated standby group number with a simple operation.

<Summary of the invention> A plurality of group numbers are stored in a memory, a predetermined group number among the group numbers is set as a standby designated group number, and the standby designated group number and the group number included in the received signal are This personal radio is configured so that it can communicate with the other party when the numbers match, and the group number stored in the memory other than the group number designated for standby and the group number included in the received signal are When a match is found, the personal radio displays a message to that effect, sets the group number as a designated standby group number by operating a predetermined key, receives a control signal sent again from the other party, and makes the other party ready for communication. It is a machine.

According to this invention, when called in a mode other than dual standby mode, it is possible to communicate with the other party promptly if necessary.

Next, the operation of the personal radio according to the present invention will be explained with reference to the flowchart of FIG. It is assumed that the first standby designated group number N _S1 is set in the 0 memory, and a group number other than the standby designated group number is set in at least one of the 2 memories, 3 memories...9 memories. . Furthermore, the second standby designation group number N _S2 that was last input and set in the input/output register 108 is read by the processor 105 and stored in the built-in general-purpose register 10.
5a-1.

(b) Now, in the standby mode when the standby key 106b is pressed, the processor 105a reads the control signal from the control signal demodulator 102e and determines whether the group number Nr included in the control signal is equal to the first designated standby group number N _S1 . determine whether

(b) If Nr=N _S1 , the processor 105a inputs the standby designation group number N _S1 to the output register 108.
, the standby designated group number N _S1 is displayed blinking on the numerical indicator 107a, and an electronic sound generator (not shown) built in the operation panel generates an electronic sound, and thereafter normal call processing is executed. In addition, when the call ends, the control section 1
05 inputs and outputs the second standby number N _S2 stored in the general-purpose register 105a-1 to the input/output register 1.
08 and display N _S2 again on the numerical indicator 107a.

(c) On the other hand, if Nr≠N _S1 , the processor 105a
determines whether the group number Nr included in the control signal is equal to the second standby designated group number N _S2 .

(d) If Nr=N _S2 , the designated standby group number is displayed blinking on the numerical indicator 107a, an electronic sound is generated, and then normal call processing is executed.

(e) If Nr≠N _S2 , the processor 105a sets 1→i.

(f) Next, the group number stored in i-memory
Determine whether Ni and Nr match.

(g) If they do not match, set i+1→i.

(H) Next, compare i and 9, and if i>9, in other words, if the received group number does not match any of the group numbers set in the memory, the next control signal will not be received. After waiting and receiving the control signal, perform the processing after step (a).

(i) On the other hand, if Ni and Nr match as a result of the determination in step (f), the processor 105a inputs a signal specifying the i key to the input/output register 108 to blink the LED element Li of the i key.

(N) After that, when the i key indicated by the flashing LED element Li is pressed, the processor 105a sets the group number Ni in the general-purpose register 105a-1 (Ni→N _S2 ), thereby changing the group number Ni. This is the designated standby group number. Also, the processor has a group number.
Ni is set in the input/output register 108, and the group number Ni is displayed on the numerical indicator 107a.

(l) After that, if the processing after step (a) is performed and the other party sends a control signal with the group number Nr again, the group numbers will match and communication will be possible, and the processor will process step (d). Let's do it.

The above is the process in standby mode, but in monitor mode when the monitor key is pressed, the above steps (f) to
Processing that is substantially the same as in (l) is performed.

In other words, the group number included in the received control signal
In the case where Nr does not match the standby designated group number, if the group number Nr matches a group number Ni other than the standby designated group number, the processor 105a selects the LED element of the i key corresponding to the i memory storing the group number Ni. flash. When the i key is pressed, the processor displays the group number Ni on the numerical indicator 107a, and also displays the group number Ni (=
Nr) is set as the standby designated group number, and thereafter, when a control signal having the group number is sent from the other party again, the device is enabled to communicate with the other party.

<Effects of the Invention> As explained above, according to the present invention, dual standby is activated when the group number stored in the memory and other than the standby designated group number matches the group number included in the received signal. In addition to displaying that it is being called by something other than the above, the i-key corresponds to the i-memory (i=0, 1, 2...9) that stores each group number, and the i-key corresponds to the memory that stores the matching group number. Since the configuration is configured such that the key is identified by a lamp or the like, and the group number stored in the memory is set as the standby designated group number by pressing the identified key, it is possible that the key is being called in a mode other than dual standby. It can be determined immediately, and it can be easily and quickly set to the group number included in the received signal or the standby designated group number by simply pressing the specified key.Therefore, by receiving the group number from the other party again, This allows you to communicate with the other party immediately, which is extremely useful when you frequently communicate with three or more people.
