Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a local disaster prevention radio device, and more particularly to redial control at the time of calling.

(Prior Art) In a disaster prevention related organization using a local disaster prevention wireless device, when a disaster occurs, it is required to frequently exchange information between the disaster occurrence regions and take appropriate measures. Therefore, in addition to the normal dialing function of transmitting the partner station number and relay station number using a numeric keypad, etc., the partner station number and relay station number are registered in the memory in the local disaster prevention wireless device. A redial function is provided to call and send contents.

(Problems to be solved by the device) However, since there are mobile stations in the local disaster prevention wireless network,
When your own station or the partner station is a mobile station and you are calling from a location different from the normal usage location, the relay station number registered in the memory and the relay station number that relays at the current location are different. Will be things. Therefore, in such a case, the relay station number registered in the memory cannot be used.
That is, the redial function cannot be used effectively.
In this case, if the own station is a mobile station, the other station can be called by a normal dial operation using the numeric keypad.However, if the other station is a mobile station, the other station can be called when the other station calls. If the relay station number used by the partner station is confirmed and not remembered, there is a problem that the partner station cannot call the partner station.

The present invention eliminates the above-mentioned problems, and provides a regional disaster prevention radio apparatus capable of calling a remote station by effectively utilizing the redial function even when the local station and the remote station are mobile stations. To aim.

[Constitution of device]

(Means for Solving the Problem) The present invention provides a decoding means for decoding a partner station number and a relay station number transmitted from a partner station or its own station before starting communication, and a decrypted partner station number and a relay station. Storage means for storing the number, display means for displaying the stored partner station number and relay station number, and the desired partner station number among the partner station numbers and relay station numbers for the plurality of displayed partner stations The above-mentioned object is achieved by providing a selecting means for selecting the number and a transmission control means for transmitting the selected partner station number and relay station number via a wireless line.

(Operation) Whether the local station or the remote station is the calling side, the local station number, the relay station number, and the remote station number are transmitted prior to the start of communication. Therefore, when the own station is the calling side, the partner station number and the relay station number are decrypted by the decryption means and registered in the storage means. When the partner station is the calling side, the partner station number and relay station number transmitted from the partner station are decoded and registered in the storage means. Therefore,
When it becomes necessary to communicate with the registered partner station, the partner station number and the relay station number displayed on the display means are selected and transmitted.

In this case, considering the same partner station, since the relay station number at the time of the latest communication is registered, even if the partner station is a mobile station, it is possible to make a reliable call using the redial function.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the present invention, which is roughly composed of a transmission / reception unit 1 and a control unit 2. The transmitting / receiving unit 1 is composed of a transmitter 11 and a transmitter 12, and the control unit 2 includes a microprocessor 21, a memory 22, a display control 23, a display unit 24, an operating unit 25, an interface 26,
27 and speaker 28.

In the above configuration, when the local station is the called side and the call signal from the partner station is received by the receiver 11, the call signal is transferred to the microprocessor 21 via the receiver 11 and the interface 26. The microprocessor 21 decodes the local station number, the remote station number, and the relay station number included in the calling signal, confirms that the remote station the remote station is trying to communicate with is the local station, and then performs the communication line connection procedure. And when the connection procedure is completed, display control
Data such as the communication mode and the partner station number, and a notification sound signal are sent to the display unit 23 to display the communication mode, the partner station number and the relay station number on the display 24, and a speaker 28 generates a notification sound. Further, the microprocessor 21 stores the data of the partner station number and the relay station number in the memory 22 before and after this operation. Then, if the user responds by the off-hook operation of the operation unit 25 with the notification sound, the transmitter 12 is activated via the interface 27, and the state in which transmission / reception can be performed is enabled.

On the other hand, when the local station is the calling side and the calling operation is performed by the operation unit 25, the microprocessor 21
12 is activated and the partner station number, relay station number and own station number set by the operation unit 25 are transmitted. Then, when the communication line with the partner station is formed, the speaker 28 generates a notification sound, and the receiver 11 is activated to enable transmission / reception. At this time, the microprocessor 21 stores the partner station number and the relay station number sent to the partner station in the memory 22.
Transfer to and store.

Therefore, regardless of whether the local station is the calling side or the called side, the relay station number used most recently by the remote station is stored in the memory 22.

Therefore, if it becomes necessary to re-communicate with the same partner station after the end of communication, when the operation unit 25 performs a station number calling operation for redial, the microprocessor 21 causes the memory
The partner station number and relay station number stored in 22 are read out and displayed on the display 24. In this case, when multiple partner station numbers are stored, all of them are displayed on the display.
Display on 24. Then, when an operation for selecting a desired partner station number from these is selected by the operation unit 25, the microprocessor 21 transfers the relay station number together with the selected partner station number to the transmitter 12 and causes it to originate. As a result, the desired partner station can be called again by the redial operation.

[Effect of device]

As described above, according to the present invention, the partner station number and the relay station number transmitted from the partner station or its own station are decoded and stored, and the stored contents are read out to perform the redial operation. Even if the partner station and the own station are mobile stations, the relay station that has been used most recently is known, and the partner station can be surely called by the redial operation for communication.
