Each of the radio kits 140_1 to 140_n of the radio devices 120_1 to 120_n includes a push to talk (PTT) button and a microphone. While the built-in PTT button is pressed by the user, the transceiver kits 140_1 to 140_n generate a PTT signal, transmit the PTT signal to the connected smartphones 130_1 to 130_n via short-range communication, and transmit the voice signal generated through the built- And outputs the voice signal included in the transceiver signal through the high output speaker to the smartphones 130_1 to 130_n connected through the near field communication and outputs the voice signal through the extension module to the smart phones 130_1 to 130_n via the expansion module. And various other functions.

The PTT button is for push-to-talk (PTT) function on the radio. The PTT function is a function that is implemented on the transceiver, and unlike a telephone, it transmits sound only while the user presses the PTT button.

The PTT button provided in each of the radio kits 140_1 to 140_n provides the same function as a conventional radio PTT button that transmits voice when the PTT button is pressed and only receives voice when the PTT button is released. This is different from a smart phone or a mobile phone, which always transmits voice even when connected to a communication network.

The smart phones 130_1 to 130_n are intelligent mobile phones to which computer support functions such as internet communication and information search are added, and various applications desired by the user can be installed. In the present invention, the smartphones 130_1 to 130_n are provided with a radio application for controlling a radio function and other additional functions.

Each of the smartphones 130_1 to 130_n performs a radio function for wirelessly communicating with smartphones belonging to the same radio group. When the PTT button of the radio kit is pressed by the user, a first transceiver signal is generated in the smartphone connected by the short distance communication with the radio kit. 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. Accordingly, the radio group performing the radio communication between the smartphones 130_1 through 130_n is composed of an originating smartphone transmitting the first transceiver signal and a receiving smart phone receiving the second transceiver 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 the smartphones 130_1 to 130_n connected to the transceiver kits 140_1 to 140_n by short distance only while the PTT button incorporated in the transceiver kits 140_1 to 140_n is pressed.

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.

The smartphones 130_1 to 130_n receive voice signals transmitted from the microphones of the transceiver kits 140_1 to 140_n to the smartphones 130_1 to 130_n while receiving the PTT signals from the transceiver kits 140_1 to 140_n, And transmits the generated first transceiver signal to the control server 110. The first transceiver signal is transmitted to the control server 110,

Upon receipt of the first transceiver signal, the control server 110 searches the group database with the unique number of the originating smartphone included in the first transceiver signal to extract the transceiver group to which the originating smartphone belongs. The extracted walkie-talkie group is composed of a calling smartphone transmitting the first radio signal and a receiving smart phone performing radio communication with the calling smart phone.

Then, the control server 110 generates a second transceiver signal including the voice signal included in the first transceiver signal, and transmits the generated second transceiver signal to each of the receiving smart phones of the extracted transceiver group.

Meanwhile, the unique numbers of the originating smartphone and the receiving smart phone are information for identifying each smart phone, and include information on at least one of the phone number of the smart phone and the serial number of the smart phone.

In addition, each of the radio devices 120_1 to 120_n may exchange voice communication signals with other smartphones (not shown) through the radio kits 140_1 to 140_n. At this time, the radio devices 120_1 to 120_n transmit a voice call signal to another smartphone only when the PTT button of the radio kits 140_1 to 140_n is pressed. Only when the PTT button of the radio kits 140_1 to 140_n is not pressed, The user can listen to a voice call signal received from the smartphone. Upon receiving a voice call signal from another smartphone, the radio devices 120_1 to 120_n can output a large voice signal of about 95 dB or more through the high output speaker built in the radio kit 140_1 to 140_n. The radio sets 140_1 to 140_n of the radio apparatuses 120_1 to 120_n transmit voice signals inputted through the built-in microphone during the voice communication of the smartphones 130_1 to 130_n connected by short- Signals to the smartphones 130_1 to 130_n connected by short-distance communication, and amplifies the voice signals received from the smartphones 130_1 to 130_n connected by short-distance communication, and outputs the amplified voice signals to the speaker. At this time, the radio kits 140_1 to 140_n may not output the voice signal received from the smartphone to the speaker while the built-in PTT button is pressed.

Further, the transceiver kits 140_1 to 140_n of the transceiver devices 120_1 to 120_n receive audio signals from the smartphone during media reproduction of the smartphones 130_1 to 130_n connected by short-range communication, The received audio signal can be amplified and output to the speaker. At this time, the radio kits 140_1 to 140_n may not output the audio signal received from the smartphone to the speaker while the built-in PTT button is pressed.

2 is a diagram illustrating a process of transmitting and receiving first and second transceiver signals and extracting a transceiver group.

Each of the smartphones 130_1 to 130_n belongs to at least one of the radio groups.

Each smartphone belongs to at least one group of radio groups named group # 1 to group # n, and each radio group has a unique group ID.

For example, when one of the outgoing smartphones 120_1 and 120_T of the group # 1 transmits the first transceiver signal to the control server 110, the control server 110 transmits the first transceiver signal to the first transceiver signal Extract the unique number of the originating smartphone included. Then, the control server 110 searches the group database 114 in which the corresponding relationship between each smartphone and the radio group is stored, and extracts the group # 1, which is the radio group to which the calling smart phone belongs.

Then, the control server 110 generates a second transceiver signal including the voice signal included in the first transceiver signal, and transmits the generated second transceiver signal to the calling smart phone (group # 1 And transmits the second transceiver signal to all the receiving smartphones 120_2 ~ 120_n, 120_R belonging to the group # 1 except for the first 120_1 and the 120_T of the second group.

Meanwhile, any one smartphone (group # 1 120_2) receiving the second transceiver signal can generate the first transceiver signal after receiving the PTT signal from the transceiver kit. In this case, the smartphone 120_2 transmits the first transceiver signal to the control server 110, and the control server 110 generates the second transceiver signal to receive the receiving smart phones 120_1, 120_3 to 120_n ).

The same is true when any one of the calling smart phones 120_1 and 120_T of the group # 2 transmits the first transceiver signal to the control server 110. [

Hereinafter, for convenience of explanation, the radio devices 120_1 to 120_n, the smartphones 130_1 to 130_n, and the radio kits 140_1 to 140_n are respectively provided with one radio device 120, a smartphone 130, a radio kit 140).

While the first transceiver signal may further include a group ID for the transceiver group.

Each smartphone 130 may have a plurality of radio groups that can communicate with each other using a radio function. When a plurality of radio groups are stored in the smartphone 130, the user can select a radio group to be radio-controlled among the plurality of radio groups, and the group ID for the radio group selected by the user is stored in the first radio signal .

If the first radio signal includes a group ID, the control server 110 searches the group database 114 by the group ID included in the first radio signal and transmits the group ID to the receiving smart phone and the receiving smart phone Can be directly extracted. The control server 110 then generates a second transceiver signal including the voice signal included in the first transceiver signal and immediately transmits the generated second transceiver signal to each receiving smartphone of the extracted transceiver group.

Meanwhile, the first transceiver signal may further include a reception list including a unique number of at least one receiving smartphone. In this embodiment, the user himself / herself decides the radio group by directly selecting the reception terminals to which the user desires to make a radio call using the radio function among the contacts stored in his / her smart phone, and the reception smart phones of the determined radio group and the radio Function can be used to make a radio communication.

When the first radio signal includes a reception list, the control server 110 generates a radio group consisting of an originating smartphone transmitting the first radio signal and each receiving smartphone of the reception list, And transmits the second transceiver signal to the smartphone.

FIG. 3 is a block diagram illustrating a control server 110 in a walkie-talkie service system using a walkie-talkie kit and a smartphone according to the present invention.

3, the control server 110 includes a reception unit 111, a unique number extraction unit 112, a radio group extraction unit 113, a group database 114, a transmission unit 115, a transmission confirmation unit 116 A retransmission unit 117, an authentication unit 118, and a setting unit 119. [

The receiving unit 111 receives the first transceiver signal from each transceiver 120. The first transceiver signal includes a unique number and a voice signal of the originating smartphone and further comprises at least one of a receiving list including the group ID of the radio group selected by the user and the unique number of each receiving smart phone selected by the user .

When the first transceiver signal is received in the receiver 111, the unique number extractor 112 extracts the unique number of the originating smartphone from the first transceiver signal and provides the extracted unique number to the transceiver group extractor 113.

The radio group extracting unit 113 searches the group database 114 by the extracted unique number and extracts the radio group to which the calling smartphone having the extracted unique number belongs. The extracted radio group is composed of an originating smartphone transmitting the first radio signal and at least one receiving smart phone communicating wirelessly with the originating smartphone.

As described above, if the first transceiver signal includes any of the group ID and the reception list of the transceiver group, the transceiver group extractor 113 directly extracts the transceiver group from the first transceiver signal.

The group database 114 stores a correspondence relationship between each smart phone 130 and a radio group and includes a unique number for each smart phone 130, a radio group to which each smart phone belongs, The transceiver group ID is stored in a database for each transceiver group.

The transmitting unit 115 generates a second transceiver signal based on the received first transceiver signal and transmits the second transceiver signal to each receiving smart phone belonging to the transceiver group extracted by the transceiver group extracting unit 113. [ At this time, the second transceiver signal is not transmitted to the calling smart phone which transmitted the first transceiver signal.

Here, the second transceiver signal includes a voice signal included in the first transceiver signal, and may further include at least one of a transceiver ID and a reception list for a transceiver group to be wirelessly communicated.

Each smartphone 130 may be configured to transmit a corresponding acknowledgment signal to the control server 110 when receiving the second transceiver signal. Corresponding to this, the call confirming unit 116 confirms whether or not the second transceiver signal is properly transmitted to each receiving smartphone of the transceiver group by receiving the acknowledgment signal transmitted from each receiving smart phone.

The origination confirmation unit 116 collects the reception confirmation signal from each reception smartphone and identifies the reception smartphone that has not transmitted the reception confirmation signal to the control server 110 side. It can be determined that the receiving smartphone which has not transmitted the acknowledgment signal to the control server 110 has not received the second transceiver signal in the case of departing from the talking area or in the shaded area.

When a smart phone that does not transmit the acknowledgment signal corresponding to the second transceiver signal is communicatively connected among the receiving smart phones of the extracted transceiver group, the retransmission unit 117 transmits the second transceiver signal .

The authenticating unit 118 compares the unique number of the smartphone 130 with the information stored in the group database 114 when the smartphone 130 accesses the control server 110 for the first time, And confirms the transceiver group of the smartphone 130. If the unique number of the smartphone does not exist in the group database 114, the smartphone 130 can not access the control server 110 and perform the radio function.

The setting unit 119 stores new information in the group database 114 or updates stored information. The setting unit 119 registers the new smartphone 130 as a specific radio group in the group database 114 based on the setting information input from the manager of the control server 110 or the setting information input from each smartphone, A role of changing the radio group of the registered smart phone 130, and the like.
