When the PTT button is pressed by the user, the first transceiver signal is generated in the smartphone in which the PTT button is pressed. Hereinafter, a smartphone transmitting a first radio signal is defined as a calling smart phone, and at least one smart phone receiving a second radio signal to be described later is defined as a receiving smart phone. Therefore, the radio group performing the radio communication between the smartphones 130_1 to 130_n is composed of a calling smart phone for transmitting the first radio signal and a receiving smart phone for receiving the second radio signal.

In the present invention, the first transceiver signal is a signal transmitted from each of the smartphones 130_1 to 130_n to the control server 110, and includes a voice signal and a unique number of the calling smartphone. The first transceiver signal is generated in each of the smartphones 130_1 through 130_n only while the PTT button embedded in the docking devices 140_1 through 140_n is depressed.

The second transceiver signal is a signal transmitted from the control server 110 to the smartphones 130_1 to 130_n, and includes a voice signal included in the first transceiver signal. The second transceiver signal includes the same voice signal as the voice signal included in the first transceiver signal.

When the PTT signal is received, the smartphone 130 connected to the docking device 140 by short-distance communication converts the micro-input sound into the voice signal only during the reception of the PTT signal (S30).

Then, the smartphone 130 connected to the docking device 140 by short-distance communication generates a first transceiver signal including a voice signal and a unique number of the calling smartphone, and transmits the first transceiver signal to the control server 110 (S40).

The control server 110 extracts the unique number of the calling smartphone included in the received first radio signal (S50), searches the group database 114 using the extracted unique number, and transmits the first radio signal to the calling smart phone And a receiving smart phone and a receiving smart phone to make a radio communication with the calling smart phone (S60).

5, if the first transceiver signal includes the group ID for the transceiver group, the control server 110 extracts the transceiver group immediately using the group ID included in the first transceiver signal in step S60 can do. On the other hand, if the first radio signal includes the reception list including the unique number of each reception smartphone selected by the user, the control server transmits the first radio signal to the calling smart phone and the reception smart You can also create a radio group consisting of phones.

Then, the control server 110 generates a second transceiver signal including the voice signal included in the first transceiver signal, and transmits the second transceiver signal to each receiving smart phone belonging to the extracted transceiver group (S70). At this time, the control server 110 does not transmit the second transceiver signal to the calling smart phone that has transmitted the first transceiver signal.

The smartphone 130 receiving the second transceiver signal extracts the voice signal from the second transceiver signal in step S80 and transmits the extracted voice signal to the docking device 140 connected in short-distance communication in step S90.

The docking device 140 connected to the smartphone 130 receiving the second radio signal amplifies the received voice signal and outputs the amplified voice signal to the speaker (S100). The received voice signal can be amplified to 95 dB or more and output through the speaker.

Meanwhile, the smartphone receiving the second transceiver signal may transmit an acknowledgment signal to the control server 110 to confirm that the second transceiver signal has been received (S110).

The control server 110 confirms the acknowledgment signal received from each of the receiving smart phones (S120), and transmits an acknowledgment signal when the communication is established between the receiving smartphone of the extracted transceiver group and the smartphone not transmitting the acknowledgment signal The second radio signal is retransmitted to the non-smartphone (S130).

6 is a flowchart illustrating a pairing process between a smartphone and a docking device.

The docking device 140 is equipped with a pairing button (not shown) for pairing of short-distance communication such as Bluetooth.

The docking device 140 detects that the pairing button is pressed by the user (S200).

When the pressing of the pairing button is detected, the docking device 140 searches for a smartphone in which the short-distance communication is activated in the vicinity (S210).

Then, the docking device 140 performs pairing by connecting to the searched smart phone through short-distance communication (S220).

As described above, various methods of short range communication may be used in the present invention, but it is preferable that short range communication of Bluetooth is used.

7 is a diagram illustrating an authentication process between a smartphone and a control server.

The transceiver application 131 may be installed from various sites providing the control server 110 or mobile application, or may be installed from an installation file provided directly.

When the radio application 131 is executed in the smartphone 130, the radio application 131 first accesses the control server 110 using the stored connection address of the control server 110 (S320).

The control server 110 compares the unique number of the smartphone 130 transmitted by the transceiver application 131 with the information stored in the group database 114 to determine whether the smartphone 130 is a terminal capable of using the transceiver service And authentication is performed on that (S330).

Hereinafter, a process of creating or changing a radio group will be described.

The generation and modification of the radio group may be performed by the user on the smart phone 130 side or may be performed only by the control server 110 side on the control server 110 side.

8 is a flowchart illustrating a process of creating or changing a radio group.

First, the smartphone 130 generates a reception list based on the setting information input from the user (S410). The reception list means a list including unique numbers of each receiving smart phone selected by the user.

For example, the user can input setting information by selecting at least one contact from among the contacts stored in the smart phone 130 to make a radio call using the radio function, The controller 131 generates a reception list based on the input setting information, and generates a first transceiver signal further including a reception list.

Meanwhile, the user can input setting information for changing the content of the radio group stored in the smart phone 130 in such a manner that a new smart phone is incorporated into a specific radio group or a specific smartphone is deleted from a specific radio group .

The smartphone 130 transmits the first transceiver signal including the reception list to the control server 110 (S420).

The setting unit 119 of the control server 110 generates a transceiver group including the calling smart phone that has transmitted the first transceiver signal and the receiving smart phone included in the reception list of the first transceiver signal at step S430. The information about the created radio group is stored in the group database 114. [

The transmitting unit 115 of the control server 110 transmits the list of the radio groups including the second radio signal and the unique number of each smartphone belonging to the generated radio group group to each receiving smart phone included in the reception list ).

Each smartphone 130 that has received the list of radio groups stores the list of radio groups and allows radio communication with the radio group by the user's choice (S450). The smartphone 130, which allows radio communication with the radio group, extracts the voice signal included in the second transceiver signal and outputs the voice signal extracted through the high-power speaker.

Although not shown in the figure, when a radio group is created or changed on the control server 110 side, the control server 110 receives setting information from an administrator through the setting unit 119 to create or change a radio group . Then, the control server 110 performs steps S430 to S450.

The method of the present invention can also be embodied as computer readable code on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission via the Internet) .
