Description

[0001] The present invention relates to a RoIP gateway for communicating with different radio groups by interconnecting different n radio groups,

The present invention relates to a RoIP gateway for interconnecting different n radio groups to enable communication between different radio groups. More particularly, the present invention relates to a RoIP gateway in which a plurality of different radio- To interconnect different n radio groups capable of providing a single wireless communication network to enable inter-radio group-to-group communication.

Generally, in a region where a mobile phone is not able to make a call or a call sensitivity is low and a call is very poor, or in a region where a call is congested, it is preferable to make a call It is often effective to make a direct call without going through a base station by sharing the frequency (band) of the base station, and these radios are adopting a half duplex communication method.

In other words, since the transceiver is capable of transmitting signals in two directions between two points of communication, it is possible to receive signals only at one point while receiving signals at other points. In order to transmit signals, PTT (Push To Talk) function, which requires explicitly changing the transmission direction, is used.

Among these PTT-type radios, the most widely used family radio service (FRS) is a 27 MHz (vehicle), 448 MHz, or 462 MHz ultra high frequency (UHF) band allocated to use freely without using radio waves It is mainly used, and its propagation distance is within 3Km.

In the case of commercial radios, the frequency of microwave (VHF) or microwave (UHF) is set to a certain amount and paid for, and its propagation distance is formed within 10 Km to 20 Km. However, the cost is lower than that of mobile phones.

In addition, such a living radio and a commercial radio (hereinafter referred to as a "portable radio") has a smaller time difference between a time when a call is made on the transmitting side and a time when the call is received on the receiving side. In other words, if you do not have time to connect the call and ring the bell like a mobile phone, for example, by pressing the portable walkie-talkie PTT on the calling side, the portable walkie speaker on the receiving end can hear the caller's voice in a short time.

Such a portable radio is very useful because it is inexpensive and easy to use because of its advantages such as the increase in the number of users and the transmission of the PTT.

However, in the case of radios used in fire stations, police stations, military units, etc., there is no mutual communication compatibility due to the use of a specific frequency band or a specific channel. Therefore, when a disaster or emergency rescue occurs, , Control, and communication are not systematically implemented.

FIG. 2 is a functional block diagram of a RoIP gateway for interconnecting different n radio groups proposed in the present invention to enable communication between different radio groups.

Hereinafter, with reference to the drawings, a description will be made of a " RoIP gateway " which is used in the present invention to enable mutual radio group communication between different n radio groups.

1 is an external perspective view of a gateway proposed in the present invention, and Fig. 2 is a functional block diagram of a gateway proposed in the present invention.

As shown in FIG. 1, the gateway of the present invention has a matrix-type keypad on the left side and eight channel ports on the right side where the transceiver is connected.

That is, the keypad unit of the present invention comprises a keypad of an m X n matrix structure, m represents the number of groups, n represents the number of channel ports, and m and n are natural numbers of at least 2 or more.

The gateway of the present invention shown in FIG. 1 has a keypad unit, a control unit, a plurality of RoIP modules 1 to 8, and a plurality of channel ports CH1 to CH8, as shown in FIG.

As shown in the figure, the keypad unit of the present invention includes channel port information CH1 to CH8 and group information Group1 to Group4.

The channel port information is represented by CH1 to CH8, but this is an embodiment and can be expanded as needed. Here, the channel port information CH1 to CH8 represents channel ports (CH1 to CH8) interlocked with RoIP modules 1 to 8 to which different radios are connected.

The group information indicates information of channel ports grouped together and capable of mutual communication.

2, the two channel ports CH1 and CH2 are classified into group 1, the two channel ports CH3 and CH4 are classified into group 2, and the four channel ports CH5 to CH8 Are classified into Group 3.

Accordingly, when grouped by the keypad unit as described above, the radio group connected to the channel port 1 and the radio group connected to the channel port 2 can communicate with each other.

Similarly, a radio group connected to channel port 3 and a radio group connected to channel port 4 can communicate with each other, and mutual communication is possible between the radio groups connected to channel port 5 through channel port 8 .

For reference, in the specification of the present invention, a state in which mutually connected channel ports are mutually connected is referred to as a patch state or a patch state.

Meanwhile, the gateway of the present invention may perform a function similar to the above through a computer or the like in addition to the keypad unit.

Next, the control unit of the present invention includes a patch control module and a floor control module as shown in the figure.

The patch control module stores the channel port patch (connection) status information input by the user through the keypad or the computer, and provides the reference for the voice control module. Since the patch setting through the computer is also available in the conventional case, the keypad unit newly proposed in the present invention will be mainly described.

The operation process of the patch control module according to the present invention is as follows.

First, when the patch setting information is input to the patch control module through the keypad unit, the patch control module determines whether the inputted patch setting information exists.

If there is no previously set patch information, information of the corresponding patch information is stored according to the inputted patch setting information.

If the previously set patch setting information exists, the existing patch setting information is deleted and then the newly inputted patch setting information is stored.

For example, when CH1 and CH2 are set in the group 1 through the keypad unit, the patch control module determines whether CH1 and CH2 belong to another group, for example, group 2 or group 3, and belongs to another group If not, the input patch setting information, that is, information for setting CH1 and CH2 in group 1, is stored as it is.

Next, the floor control module checks whether or not the audio of the radio connected to each channel port (channel ports 1 to 8) is input. If an audio input is detected, the floor control module checks whether the channel port is set by the patch control module, If the channel is in a patch state, it is confirmed whether another channel in the group is already speaking. If the channel is in a state capable of speaking, audio is transmitted to all channels in the group to which the channel is patched.

Next, a plurality of RoIP modules, which are another component of the present invention, and a plurality of channel ports interlocked therewith will be described.

As shown in the figure, in the embodiment of the present invention, eight RoIP modules and eight channel ports (channel ports 1 through 8) interlocking with the eight RoIP modules are provided.

First, the channel port will be described.

A predetermined transceiver is connected to the channel port of the present invention. The channel port is provided with a PTT terminal, an audio output terminal, an audio terminal, and a COR (Carrier Operated Relay) terminal.

The transceiver connected to the channel port usually has a PTT terminal, an audio output terminal, and an audio terminal, but there may or may not be a COR terminal in the transceiver. In consideration of this point, in the present invention, in order to extend the versatility of the gateway, a COR terminal is additionally provided to the channel port, which may be an optional element. For reference, in case of a transceiver that does not provide a COR terminal, the audio input signal is analyzed to judge whether or not the sound is input.

Next, a plurality of RoIP modules are interlocked with corresponding channel ports 1 to 8 as shown in the figure.

The RoIP module of the present invention is connected to a transceiver connected to a corresponding channel port through an audio input / output terminal, a PTT terminal, and a COR terminal. The VoIP-related protocol stack such as SIP and RTP and a voice codec, And performs voice communication between the groups.

Hereinafter, the functional operation of the " RoIP gateway " which enables inter-group communication between different radio groups by mutually connecting n different radio groups will be described in the present invention.

For ease of explanation, it is assumed that there are three groups.

Assume that group A refers to the group that has the radio used by firefighters, group B refers to the group that has the radio used by the police officers, and group C refers to the group that has the radio used by the soldiers. The groups belonging to the group B can only talk within the group A through the radio that they have, and the groups belonging to the group B can talk only within the group B through the radio that they have. In the group C, It will only be possible to talk within the C group through the radio.

However, in cases where a disaster or an emergency occurs in a specific area and all of the groups A, B, and C are involved, it often happens that other groups must communicate with each other.

In this case, after the gateway of the present invention shown in FIG. 2 is installed, a predetermined radio to be used in each of the groups A, B, and C is connected to an arbitrary channel port of the eight channel ports.

For example, it is assumed that the transceiver used in group A is connected to channel port 1, the transceiver used in group B is connected to channel port 2, and the transceiver used in group C is connected to channel port 5.

Next, in order to enable the communication between these three groups, the CH1 corresponding to the channel port 1, the CH2 corresponding to the channel port 2, and the CH5 corresponding to the channel port 5 in the keypad section must be grouped into patches something to do.

The gateway manager selects, for example, a keypad corresponding to CH1, CH2, and CH5 located in group 1 so that all three groups can communicate with each other.

The patch information thus set is transmitted to and stored in the patch control module.

Next, if the transceiver belonging to the group A is called A1, and the transceiver selects the PTT from the A1 transceiver and then makes a call, the transceiver transmits the radio communication signal to the other transceiver (A2, A3, A4 ...) (Audio) signal is transmitted to the RoIP module 1 through the audio input terminal of the channel port 1 after it is transmitted to the radio unit connected to the channel port 1 as well as the audio port.

In the RoIP module 1, there is a VAD (Voice Activity Detector) for detecting whether an audio signal is inputted. The detected audio signal is converted into a digital audio signal through an AD converter, and then transmitted to a floor control module of the control unit.

When the digital audio signal is received, the voice control module inquires of the patch control module to check whether or not a channel port patched to the channel port 1 exists.

In the case where there is no other channel port patched together with the channel port 1, the voice control module maintains the initial operation mode. However, when confirming information that the channel port 2 and the channel port 3 are mutually patch-connected as in the present invention, The digital audio signal transmitted from module 1 is transmitted to RoIP module 2 and RoIP module 3 connected to channel port 2 and channel port 3.

In the RoIP module 2 and the RoIP module 3, the digital audio signal transmitted from the voice control module is extracted through the DAC converter and then transmitted to the radio port connected to the channel port 2 and the channel port 3 through the audio output terminal. At this time, the RoIP module 2 and the RoIP module 3 turn on the corresponding PTT terminal and control so that the audio signal can be transmitted from the connected radio.

That is, in the RoIP module 2 and the RoIP module 3, the PTT-on signal is transmitted to the PTT terminal of the RoIP module 2 and the RoIP module 3 by the control of the voice control module, and the digital audio signal received, for example, in the RTP packet, Signal and outputs it to the audio output terminal of RoIP module 2 and RoIP module 3, so that transmission to B group and C group is possible.

Therefore, it is possible to communicate with the radio users of B group and C group connected to channel port 2 and channel port 3 respectively.

As described above, when using the gateway according to the present invention, it is possible to make a real-time communication among a plurality of groups using a heterogeneous transceiver.

More specifically, it is possible to make mutual communication between different radio systems with different frequencies and modulation methods such as VHF, UHF, and TRS.

In addition, when the gateway of the present invention is linked with an IP network, the IP-based packet audio transmission technology is applied, and the communication quality is excellent and the communication connection with another wired / It is possible to provide universal scalability.

That is, the gateway of the present invention is advantageous in that communication can be performed at any time without restriction of location or distance by enabling interconnection of different frequency bands as well as connection of another frequency band wireless communication network.

As described above, the RoIP gateway, which enables mutual communication between different radio groups by interconnecting different n radio groups according to the present invention, is configured to set a group enabling a single radio network communication in the keypad unit, And stores it in the patch control module.

Therefore, when one of the predetermined radio groups belonging to the patched set group makes a call using his / her radio, the floor control module senses it and transmits the content of the call to the radio users of the remaining groups patched to enable single radio network communication .

In the case of using a RoIP gateway which enables mutual communication between different radio groups by interconnecting different n radio groups according to the present invention described above, it is possible to configure a single communication network in an emergency field dispatch structure team or a military squad operation, By using IP network, it is possible to construct a wireless communication network without limitation of location or distance, and it is possible to easily perform group setting for single communication by operating a keypad unit attached to a gateway.
