The present invention relates to a technology for performing communication between radios located at a long distance, and more particularly, to a radio system and a control method capable of performing communication between radios located at a long distance by using a radio by operating in conjunction with an internet network. will be.

In general, unidirectional portable radios, which are commonly used as radios, do not need a base station or relay station for interconnection and can communicate with each other without charge. That is, there is a limit on the distance of communication, which can not be performed at long distance remote sites.

Therefore, in order to use a radio, first, it must be located within a communication distance between the radios. Due to the limitation of such communication distance, most of users are using mobile communication terminals such as mobile phones using paid communication networks provided by communication providers, and radios are used only for limited purposes in construction sites, companies, and the military. For radios with limited communication distances, there is a significant advantage in that call distances are not imposed between radios located in close proximity to each other.However, due to the uncertainty of distance limitations, users may be able to talk It is also using a paid network such as a mobile phone to perform. This trend is due to the fact that there are no systems that connect radios with each other over long distances, such as base stations or relay stations, rather than the performance of radios is significantly lower than other mobile communication terminals. Therefore, it would be great news for users if they could take advantage of the existing radios and communicate with each other over long distances.

Accordingly, an object of the present invention is to provide a radio system and a control method for interworking with the Internet to perform a long distance communication between the radio by interworking the radio with the Internet network to solve the above problems.

The operation flow of B 71 is shown.

The brief steps of the above control flow are as follows.

Performing a wireless communication with the charger in the radio to transmit a call voice to the charger as a wireless signal, and outputting a voice signal received from the charger to a speaker;

When the wireless signal is transmitted from the radio, the charger converts the corresponding radio signal, and then transmits a signal and data including a radio communication request to the connected computer, and receives the signal and data from the computer. A conversion step of converting the transmission to the radio;

If the computer receives a radio communication request from the charger, an Internet interworking step of automatically connecting to the other computer registered through the Internet telephone service to maintain communication with the other computer; at least should be provided.

The overall operation of the radio system interworking with the Internet through the above control flow will be described in detail.

First, when the channel is selected by the channel selection key 123 of the radio A (11) in step 401 proceeds to step 402 to convert the voice input through the microphone into a wireless signal to transmit to the charger A (20). . Then, in step 501, the charger A 20 receives the radio signal from the radio A 11. In step 502, the charger A 20 converts the radio signal into a signal and data for a computer in the signal / data converter 215. In the step SNK computer A 30 transmits the signal and data to the radio communication request signal and the audio signal converted into computer signals and data. Then, the computer A 30 checks whether the signal and data are received from the charger A 20 in step 601 and receives it in advance by using an Internet telephone service, for example, the dial pad or the wow call. The registered partner computer B 50 is called through the Internet network 40. In step 701, the computer B 50 sends a response signal back to the computer A 30 when there is a call according to the Internet phone service from the computer A 30 located at a remote location. When the computer A 30 detects that the computer B 50 is connected to the computer B 50 through an internet phone service, the computer A 30 proceeds to step 604 to receive the signal and data received from the charger A 20 on the Internet network 40. Is sent to the computer B (50). Then, when the computer B 50 receives the signal and the data through the Internet network 40 in step 703, the computer B 50 sends the same to the charger B 60 in step 704. Then, the charger B 60 confirms that there is a signal and data reception from the computer B 50 in step 801 and converts it to a wireless signal in step 802. In operation 803, the transceiver B transmits to the transceiver B 71. In step 901, when the radio signal is received from the charger B 60, the transceiver B 71 demodulates and amplifies the voice, and outputs the voice through the speaker in step 903. If the voice is input through the microphone in step 904, the transceiver B 71 proceeds to step 905 and converts the voice signal into a wireless signal and transmits it to the charger B 60. Then, in step 804, when the wireless signal from the radio B 71 is received, the charger B 60 proceeds to step 805 to convert the received wireless signal into computer signals and data, and then the computer B 50 in step 806. To be sent. If there is a signal and data received from the charger B 60 in step 705, the computer B 50 proceeds to step 706 and sends the corresponding signal and data to the computer A 30 through the Internet network 40. Send it out. In operation 605, the computer A 30 transmits the signal and data received through the Internet network 40 to the charger A 20 in step 606. When the charger A 20 receives the computer format signal and data received from the computer A 30 in step 504, the charger A 20 converts the signal and data into a wireless signal in step 505 and then sends the signal to the radio A 11 in step 506. do. When the radio A 11 receives the wireless signal from the charger A 20 in step 403, the transceiver A11 amplifies the voice and outputs the voice through the speaker in step 405.

The control is performed as in the operation of the above-described internet interworking radio system, so that the radio A 11 and the radio B 71 can communicate with each other even if they are located at a long distance, and are currently provided free of charge on the Internet. If you provide an internet phone service such as a dial pad, you can communicate with the other party's radio at a long distance free of charge.
