Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable communication device in a fishing area information system.

0002

[Prior Art] The fishing area information system, which has become popular in recent years and is known as Marine Horn, uses a system ID code that specifies a relay device, a preamble code following the system ID code, and a mobile phone communication system of the called party. Communication is started using data consisting of four codes: a partner station ID code consisting of a 4-digit numerical value that specifies the device, and a calling station ID code consisting of a 4-digit numerical value indicating the mobile communication device of the calling party. The structure is as follows. Then, on the side of the mobile communication device in the standby state, the partner station ID
A configuration is adopted in which it is determined whether the code matches its own code or not, and when the code matches, an operation for communication is started.

0003

[Problem to be Solved by the Invention] As described above, each mobile communication device determines whether the other station's ID code matches its own code, and if they match, it starts communication. However, in this system, the mobile communication device designated as the communication partner must return a response within 10 seconds unless the mobile communication device of the calling party transmits, and if the mobile communication device specified as the communication partner does not send a response after 10 seconds. If the call is delayed, the call will be terminated and the relay device will stop the relay operation. For this reason, the called party must immediately return a response, so in the case of mobile communication devices, where there are many chances that there will be no one in the vicinity, it is rare for there to be a person in the vicinity when the call is made. Therefore, in most of the calling operations for this mobile communication device, the call ends without starting communication. In other words, a problem has arisen in that the mobile communication device that made the call has to make the call many times in order to start communication.

The present invention was conceived to solve the above problem, and its purpose is to display the ID code of the mobile communication device that made the call when the user is away from home and receives a call. An object of the present invention is to provide a portable communication device in a fishing area information system that can be used.

[0005]

[Means for Solving the Problems] In order to solve the above problems, a mobile communication device in a fishing area information system according to the present invention makes a call by using the ID code of the mobile communication device on the called side as the ID code of the other station. When the ID code of the side mobile communication device is used as the calling station ID code, an ID code determination section that determines whether the received partner station ID code matches its own ID code, and an output of this ID code determination section. and a display unit that displays the calling station ID code of the mobile communication device that transmitted the partner station ID code when the ID code of the other station indicates a match and the call is not started, the output of the ID code determining unit indicates a match. an ID code storage unit that stores the calling station ID code of the mobile communication device that transmitted the partner station ID code each time the situation occurs and the call is not started. A configuration is used in which the calling station ID code stored in the calling station is displayed on the display unit. The apparatus is also provided with an incoming call display that indicates that there is a call, and when the output of the ID code determination section shows a match and the call is not started, the incoming call display displays that there is a call.

FIG. 3 is an explanatory diagram showing the structure of data used at the time of calling. The operation of one embodiment of the present invention will be described below with reference to the same figure as necessary.

[0014] When calling the other party, use the keyboard 19
is used to set the partner station ID code and instruct to start transmission (at this time, the partner station ID code is displayed on the display 15 via the key input control section 18 and the display control section 16). The main control unit 24, which has been given the partner station ID code and the instruction to start transmission by the key input control unit 18, gives an instruction to the reception control unit 23 to monitor the output of an empty channel, and also gives an instruction to the PLL oscillation unit 29. By this,
A channel whose empty channel output indicates empty is searched. Then, the frequency of the transmitter 28 is set to the found channel, and the transmission controller 25 is provided with the partner station ID.
Send code.

The transmission control unit 25 to which the partner station ID code has been given transmits the system ID code 51, preamble code 52, partner station ID code 53, and calling station ID code 54 to the DTMF encoder 26 in order. The code is sent to the transmitter 28 as a DTMF signal.
send more.

When the transmission of the above code is completed, the main control section 24 stops the operation of the transmitting section 28 and starts the operation of the receiving section 30. Since the called mobile communication device responded, this answer back code is received by the receiving unit 30, and the main control unit 24, which is indicated to have received the answer back code via the DTMF decoder 22 and the reception control unit 23, Based on the output of the PTT switch 17 guided through the key input control section 18, the PTT
Control is performed such that when the T switch 17 is pressed, transmission is performed, and when it is not pressed, reception is performed.

This completes the explanation of the operation when called, and the operation when called next will be explained.

The main control section 24 sets the reception section 30 to a reception state, changes the output frequency of the PLL oscillation section 29, and causes the reception section 30 to perform a channel scan reception operation. When the preamble code 52 is received during this scanning operation, the reception of the preamble code 52 is indicated to the main control unit 24 via the DTMF decoder 22 and the reception control unit 23. Therefore, the main control unit 2
4 fixes the receiving frequency to the channel at that time.

[0019] The partner station ID code 53 received next to the preamble code 52 is read as a four-digit numerical value by the ID code reading section 11 to which the output of the DTMF decoder 22 is guided. Then, the read value is the ID
The code is guided to the code determination section 13. The ID code determination unit 13 determines whether the derived numerical value matches a previously stored numerical value, and sends the determination result to the main control unit 24.

In this determination, the partner station ID code 53
If the numerical value does not match the stored numerical value, since these series of signals are signals for calling a different mobile communication device, the main control unit 24 terminates the reception of this channel, and Performs control to restart channel scan operation.

Further, in the above judgment, if the numerical value of the partner station ID code 53 and the stored numerical value match,
Subsequently, the calling station ID code 54 is received. Then, the calling station ID code 54 received by the receiving unit 30
is sent to the ID code storage unit 1 as a 4-digit numerical value via the DTMF decoder 22 and the ID code reading unit 11.
2 is sent out. Furthermore, when the reception of the calling station ID code 54 is completed, the main control section 24 sets the transmitting section 28 to the transmitting state and gives an instruction to the transmitting control section 25 to transmit the answer back code. Therefore, the answer back code is sent out from the DTMF decoder 22 and transmitted from the transmitter 28. The main control unit 24 also sends a calling signal to the audio circuit unit 20 and causes the speaker 21 to generate a ringing tone.

Next, when the PTT switch 17 is pressed to start a call, the main controller 24 controls the PTT switch 17 based on the output of the PTT switch 17 via the key input controller 18.
Control is performed such that when the T switch 17 is pressed, transmission is performed, and when it is not pressed, reception is performed. Also, ID code storage section 1
2, P via the key input control section 18 and main control section 24.
When it is indicated that the TT switch 17 has been pressed, the already given numerical value of the calling station ID code 54 is discarded without being stored internally.

Further, when the above-mentioned ringing tone is transmitted from the speaker 21 to indicate that there is a call, if the PTT switch 17 is not pressed contrary to the instruction (if there is no person near the portable communication device) If there is no one),
A few seconds later, the relay operation by the relay device ends.

At this time, the end of the relay is indicated by the empty channel output, so this end is indicated by the reception control section 2.
3 to the main control unit 24. Therefore, the main control unit 24 uses the ID to indicate that the call ended without starting.
Instruct the code storage unit 12. I given this instruction
The D code storage unit 12 stores the already given calling station ID.
The numerical value of the code 54 is stored internally and sent to the display control section 16. The display control unit 16 performs control to display the numerical value of the calling station ID code 54 given by the ID code storage unit 12 on the display 15, and also controls to light the incoming call display 14 to indicate that there is an incoming call. I do.

[0025] Thereafter, when there is a call and a call is not started in response to the call, the ID code storage section 12 sequentially stores therein the numerical value of the calling station ID code given from the ID code reading section 11. At the same time, the numerical value of the calling station ID code given from time to time is sent to the display control section 16. Therefore, the latest calling station ID code in the calling history is displayed as a numerical value on the display 15.

Furthermore, when an instruction to display the history is inputted using the keyboard 19 via the key input control unit 18 and the main control unit 24, the internal memory is The numerical values of the calling station ID codes that have been displayed are sequentially sent to the display control section 16 and displayed on the display 15. Further, the incoming call display 14 stops lighting up the incoming call display when an instruction to turn off the light is given from the keyboard 19 or when the PTT switch 17 is pressed.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be configured to perform the same operations. I explained the case where the configuration is
If the PTT switch 17 is not pressed within a certain period of time after the ID code determination unit 13 outputs a match, it may be determined that the call has not been made.

As explained above, in this embodiment, by providing the ID code storage section 12, when a situation occurs in which a call cannot be started, the numerical value of the calling station ID code is stored each time the situation occurs. Even if multiple calls occur while you are away, the calling station ID codes corresponding to all of the calls are stored in numerical value, so you can easily return them to your mobile communication device. At times, it is possible to respond to all calls while the employee is away.

Furthermore, since the incoming call display 14 is provided, if there is a call while you are away, the fact that the call has been received will be displayed more clearly, so you will not be able to overlook the fact that there was a call. It is possible to prevent this.

[0030]

[Effects of the Invention] The portable communication device in the fishing area information system of the present invention starts a call when the ID code determination unit that determines the ID code of the other party indicates that a call has been made to itself. If there is no call, the ID code of the calling station is displayed on the display, so even if the call is made while the user is away, the ID code of the mobile communication device that made the call will be displayed. This has the effect of making it possible.
