Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a wireless device, such as a personal wireless device, that performs communication by setting a group number.

Conventional configuration and problems thereof Conventional personal radios always display the group number during a call operation, which has the disadvantage that the group number can be known to a third party.

Purpose of the invention The purpose of this invention is to eliminate the above-mentioned problems of the conventional method, and the purpose is to enable the user to display or erase a 5-digit display at his/her discretion by key operation. It is.

Structure of the Invention In order to achieve the above object, the present invention determines a function mode code input from a key input device, and displays or erases a group number in accordance with the function mode code.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 schematically shows a personal radio device which is an embodiment of the present invention. In FIG. 1, 1 is a group number display device, and this group number display device 1 displays a five-digit group number input from a key input device 3. Reference numeral 2 denotes a device status indicator 2 that displays the status of the personal radio. For example, this device status indicator 2 displays "READY" when the device is in a standby state, and displays "TALK" when the device is in a talking state. 4 is a display interface, which displays the group number display 1, based on display data output from the central processing unit (CPU) 6;
Controls the equipment status indicator 2. 5 is a key input interface, and this key input interface 5 transmits key input data input from the key input device 3 to the CPU 6. 7 is a random access memory (RAM) within the CPU 6, and 8 is a read-only memory (ROM) that stores a program for controlling the CPU 6. 9 is an input/output interface, and this input/output interface 9 is connected to a modulation/demodulation circuit (modem) 12 and a radio device 13.
This is for connecting to CPU6. 10 is a timer within the input/output interface 9, and this timer 10 manages the time of the CPU 6. 11
is an IDROM in which the license number is stored; 14 is a phase locked loop (PLL) provided in the radio 13; 15 is a microphone for inputting audio;
16 is an antenna, and 17 is a speaker that outputs an audio signal. The CPU 6 reads the license number stored in the IDROM 11 and the group number stored in the RAM 7, specifies the wireless channel, sends and receives control signals (synchronization signal, group number, channel number for communication, license number), and uses the microphone 15. It has functions such as operation when the press-talk switch provided on the terminal is pressed, control of the display, and connection and control of telephone calls.

The personal radio shown in Figure 1 is a simple radio station that uses radio waves in the 900MHz band.
80 channels are assigned every 25KHz (channel 1 is a control channel, channels 2 to 80 are communication channels). The user inputs the group number (calling number) of the other party using the key input device 3, and displays the input group number on the group number display 1 via the CPU 6. In addition, the input group number is
It is held in RAM7. Figure 2 shows the key input device 3.
If you want to store the group number in RAM 7, press "0", "*", "0" in Figure 2.
Further, by pressing "1", "2", "3", "4", and "5", the group number "12345" is stored in the "0" position of the group number memory of the RAM 7. By the same operation, other group numbers can be stored in the "1" to "9" positions of the group number memory.

When making a phone call, the other party's group number is read out from the group number memory or inputted from the key input device 3. The group number of the set partner is sent from the CPU 6 to the radio 13 via the modem 12.
At the same time, the CPU 6 sends the group number to the radio 13.
The radio device 13 is placed in a transmission mode, and a control signal is output from the radio device 13 via the antenna 16.

In this way, by transmitting the group number that the other station is waiting for to the other station, it becomes possible to call and talk. When calling someone like this,
First, it is necessary to set the other party's group number in the personal radio, and frequently used group numbers are stored in advance in the RAM 7 inside the CPU 6. The RAM 7 also stores a group number (reception number) for receiving a call from the other party. The group number is made up of random five-digit numbers.

This embodiment has an added function that allows the group number to be displayed or deleted arbitrarily by key input.

FIG. 3 shows a display example in which the five-digit group number display is erased using the key input device 3 shown in FIG. 2. FIG. 3a shows an example in which the group number "12345" is displayed on the five-digit group number display 1. Here, when "1" is inputted from the key input device 3, the display shown in FIG. 3b appears. Similarly, if you set "*" and "0",
The display becomes as shown in FIG. 3c and d. Here, "1*"
is a function mode code that operates the 5-digit group number display. After setting this function mode, setting "1" will display the 5-digit group number, and setting "0" will display the 5-digit group number. Can be erased. If the 5-digit group number erasure flag is set to "0" after setting the function mode as in the example of FIG. 3, the 5-digit group number display will be erased as shown in FIG. 3c.

Next, the operation for displaying the five-digit group number from the erased state as shown in FIG. 4a will be explained with reference to FIG. 4.
First, function mode "1*" is set in the same way as when erasing the 5-digit group number display. Figures 4b and 4c show the display after setting the function mode. Next, the 5-digit group number display flag “1”
Set. The display at this time is shown in FIG. 4d.
As a result, the erased group number is displayed on the five-digit group number display.

FIG. 5 shows the basic configuration of the present invention. Fifth
In the figure, 18 is a key input means, from which a group number or function mode code "1*0" or "1*1" is input. 1
9 is a display control means for displaying or erasing the group number input from the key input means 18 on the group number display 20; 21 is a display control means for determining the function mode code input from the key input means 18; It is a key input determining means that reads display control data from the data memory 22 and outputs the display control data to the display control means 19. When the function mode code "1*1" is input from the key input means 18, the group The group number displayed on the number display 20 is erased. On the other hand, when "1*1" is input, the erased group number is read out from the group number memory 23 and displayed on the group number display 20 again.

FIG. 6 shows the operation of the above embodiment. 6th
In the figure, key data is input at step A. If the key data is the display control function mode "1*", it is determined that display control is to be performed in step B, and the process proceeds to step C. At step C, "1" or "0" is input. Next step D
In step C, it is determined whether the key data input is "1" or "0". If it is determined as "0" in step D, the process proceeds to step E, and the group number display 20
The 5-digit group number displayed on the screen will be deleted. On the other hand, if it is determined as "1" in step D, the process proceeds to step F, where the group number stored in the group number memory 23 is read out and displayed on the group number display 20 again.

Effects of the invention The present invention has the above-mentioned configuration, and according to the invention, the group number can be displayed or erased arbitrarily by key operation. In particular, since the group number display can be erased arbitrarily, it is possible to prevent the group number from being known to a third party.
