[0037] In a possible implementation, the voice terminal 11 is an interface device that supports the installation of operating software. The voice terminal 11 supports functions such as calling and answering, that is, the voice terminal 11 can initiate a voice transmission request and can also respond to a voice transmission request from a peer device.

[0038] In the embodiment of the present invention, the scatter communication device 12 is a communication device improved on the basis of the existing scatter communication device. The existing scatter communication device has the ability to transmit data with other scatter communication devices through scatter channels. The scatter communication device is improved based on the existing functions of the scatter communication device to obtain the scatter communication device 12 of the embodiment of the present invention. The scatter communication device 12 of the embodiment of the present invention is used to exchange, compress and transmit voice data. The scatter devices can be interconnected by wires, such as two scatter communication devices 12 at the same site can communicate through wired interconnection. The scatter devices can also communicate through scatter channels, such as two scatter communication devices 12 at different sites can communicate through scatter channels.

[0039] In a possible implementation, the voice terminal 11 samples the user's voice at an 8k sampling rate and 16-bit width.

[0040] In a possible implementation, when the scatter communication device 12 is connected to the voice terminal 11 via Ethernet, the voice data packet sent by the voice terminal 11 received by the scatter communication device 12 is an Ethernet voice data packet. The scatter communication device 12 separates the effective voice payload in the voice data packet by parsing, and compresses the voice data according to the IIS protocol. Optionally, the AMBE compression algorithm or other voice compression algorithm is used to compress the voice into low-bitrate data, usually 2kbps data. The 2kbps voice data constitutes a voice frame, and the scatter communication device 12 sends the voice frame to the scatter communication device of the opposite device, so that the voice terminal of the opposite device obtains the voice data in the voice frame.

[0041] In a possible implementation, the process of receiving a voice transmission request sent by a peer device by the device provided in the embodiment of the present invention includes:

[0042] The voice terminal 11 is also used to receive and respond to a voice transmission request initiated by a peer voice terminal;

[0043] After establishing the voice connection, the scattering communication device 12 also receives the voice frame sent by the scattering communication device of the opposite device, decompresses the voice frame to obtain valid voice data, packages the valid voice data in a preset data format to obtain a voice data packet, and sends the voice data packet to the connected voice terminal 11;

[0045] In a possible implementation, the voice terminal 11 includes a voice collection unit 111, which is used to collect the user's voice; the voice terminal 11 also includes a voice playback unit 112, which is used to play the voice. Optionally, the voice playback unit 112 includes a speaker.

[0046] An embodiment of the present invention provides a scattering communication voice transmission device, which combines a voice terminal and a scattering communication device into a scattering communication voice transmission device. The voice terminal initiates a voice request, performs noise reduction processing on the collected voice, packages it into a voice data packet in a preset data format and sends it to the scattering communication device. After the scattering communication device completes the analysis and compression of the voice, the voice frame is sent to the scattering communication device of the opposite device. The scattering communication device of the opposite device transmits the voice data to the voice terminal of the opposite device, thereby completing point-to-point voice transmission.

[0047] Figure 2The structure schematic diagram of the scatter communication voice transmission system provided by the embodiment of the present invention is shown, which is described in detail as follows: the system includes m sites, and for each site, the site includes at least one scatter communication voice transmission device. If a site includes multiple scatter communication devices, then for each scatter communication device in the multiple scatter communication devices, the scatter communication device communicates with at least another scatter communication device of the site through wired interconnection, and for each scatter communication device of each site, the scatter communication device communicates with at least one scatter communication device of another site through scatter channel interconnection. The system is used for:

[0048] The voice terminal of the first device initiates a voice transmission request, the voice transmission request includes the ID number of the scatter communication device in the first device and the ID number of the scatter communication device of the second device, and the second device is the opposite end device of the voice transmission request;

[0049] The scattering communication device of the first device receives the voice transmission request, determines the voice transmission path through a preset network topology structure according to the ID number of the scattering communication device in the first device and the ID number of the scattering communication device of the second device, and sends the voice transmission request to the scattering communication device of the second device according to the voice transmission path, so that the scattering communication device of the second device sends the voice transmission request to the voice terminal of the second device, and when the voice terminal of the second device responds to the voice transmission request, the communication link is established;

[0050] The voice terminal of the first device and the voice terminal of the second device perform voice transmission through the voice transmission path.

[0051] Figure 2 FIG2 exemplarily shows a scattering communication voice transmission system provided by an embodiment of the present invention. FIG2 exemplarily shows four sites, namely site 1 to site 4. Each site includes at least one Figure 1 The embodiment of the present invention shown in FIG. 1 provides a scattering communication voice transmission device, such as Figure 2 As shown, the voice terminal 11-1 and the scattering communication device 12-1 constitute a scattering communication voice transmission device provided by an embodiment of the present invention, and the device is located at site 1. The voice terminal 11-4 and the scattering communication device 12-4 constitute a scattering communication voice transmission device provided by an embodiment of the present invention, and the device is located at site 2. The voice terminal 11-5 and the scattering communication device 12-5 constitute a scattering communication voice transmission device provided by an embodiment of the present invention, and the device is located at site 3. The voice terminal 11-6 and the scattering communication device 12-6 constitute a scattering communication voice transmission device provided by an embodiment of the present invention, and the device is located at site 4.

[0052] like Figure 2As shown, in actual application scenarios, a site may have multiple scattering communication devices, each of which transmits signals with one or more scattering communication devices of other sites through scattering channels, but a site only needs one or a few voice terminals to transmit voice with other sites. Based on this, in the system provided in the embodiment of the present invention, in addition to including Figure 1 The scattering communication voice transmission device shown in the figure also includes other independent scattering communication equipment, such as Figure 2 The scatter communication device 12-2 and the scatter communication device 12-3 are shown.

[0053] In the embodiment of the present invention, the first device may be any scatter communication voice transmission device in the system, and an apparatus composed of a voice terminal 11 - 1 and a scatter communication device 12 - 1 is taken as an example to illustrate the first device.

[0054] The voice terminal 11-1 needs to perform voice transmission with the voice terminal 11-4 of the site 2, and the voice terminal 11-1 initiates a voice transmission request, which includes the ID number of the scatter communication device 12-1 and the ID number of the scatter communication device 12-4. Figure 2 As shown, scatter communication device 12-1 and scatter communication device 12-5 transmit data through scatter channels, and scatter communication device 12-2 and scatter communication device 12-4 transmit data through scatter channels. After receiving the voice transmission request, scatter communication device 12-1 determines that the voice transmission path from voice terminal 11-1 to voice terminal 11-4 needs to be forwarded through scatter communication device 12-2 according to the preset network topology structure, that is, when voice terminal 11-1 sends voice data to voice terminal 11-4, it needs to be sent through scatter communication device 12-1 to scatter communication device 12-2 and then to scatter communication device 12-4, and scatter communication device 12-4 transmits the voice data to voice terminal 11-4. The transmission path from voice terminal 11-4 to voice terminal 11-1 is the same as the above, and the voice flow direction is opposite to the above.

[0055] In a possible implementation, the network topology structure in the embodiment of the present invention is used to represent the connection relationship between the scattered communication devices in the system, and the connection relationship includes communication through wired interconnection and communication through scattered channel interconnection. The network topology structure in the scattered communication device 12 can be pre-set / pre-stored in the scattered communication device, and the scattered communication device 12 can also obtain the network topology structure by the following method: before the scattered communication device 12 of the first device receives the voice transmission request sent by the voice terminal 11, the scattered communication device 12 of the first device initiates a topology query instruction, and the topology query instruction is used to obtain the ID numbers and connection relationships of all scattered communication devices in the system, and determine the network topology structure according to the ID numbers and connection relationships of all scattered communication devices 12.

[0056] In the embodiment of the present invention, the ID number of the scatter communication device is used to uniquely identify the scatter communication device in the system.

[0057] In one possible implementation, if the scatter communication device of the first device determines through a network topology structure that the scatter communication device of the first device communicates with the scatter communication device of the second device through wired interconnection or through scatter channel interconnection, then the devices in the voice transmission path from the first device to the second device include the first device and the second device.

[0058] In one possible implementation, if the scatter communication device of the first device determines through the network topology structure that the scatter communication device of the first device and the scatter communication of the second device are interconnected and communicated through at least one other scatter communication device, then the devices and equipment in the voice transmission path from the first device to the second device include the first device, the second device and at least one other scatter communication device.

[0059] In one possible implementation, after the communication link between the first device and the second device is established, the first device and the second device are in a call connection state. When the first device and the second device are in the call connection state, other devices in the system cannot establish a communication link with the first device or the second device.

[0060] In a possible implementation, after the first device and the second device complete voice transmission, the first device and the second device change from a communication connection state to a call waiting state.

[0061] In a possible implementation, the m sites include a central site and m-1 peripheral sites, m is a positive integer greater than or equal to 2, if the first device is located at the central site, the voice transmission request sent by the first device also includes a broadcast mode instruction, and the scattering communication device of the first device determines the voice transmission path between the first device and the device of each site in the m-1 peripheral sites according to the broadcast mode instruction and the network topology structure;

[0062] The first device establishes a communication link with a device at each of the m-1 outstations according to a voice transmission path between the first device and the device at each of the m-1 outstations;

[0063] After the first device completes the establishment of the communication link with the device at each site in the m-1 peripheral stations, the first device sends voice data to the device at each site in the m-1 peripheral stations.

[0064] Combination Figure 1 Site 1 is the central site, and sites 2 to 4 are peripheral sites. If the voice transmission request sent by the voice terminal 11-1 of site 1 also includes a broadcast mode instruction, at this time, the scattering communication device 12-1 broadcasts voice to the three peripheral sites, the voice 11-1 sends voice data, the scattering communication device 12-1 sends the voice frame to the scattering communication device 12-4 through the scattering communication device 12-2, sends the voice frame to the scattering communication device 12-5 through 12-1, and sends the voice frame to the scattering communication device 12-6 through the scattering communication device 12-3 to achieve the purpose of voice broadcasting.

[0065] The scatter communication voice transmission device of the central station has the highest priority. When the device composed of the voice terminal 11-1 and the scatter communication device 12-1 is in the voice broadcasting mode, the entire system, that is, the entire network broadcasts the central station voice. At this time, the peripheral station can only transmit voice with the central station in the time slot when the central station does not broadcast voice, and it is first come first served.

[0066] based on Figure 1 The devices provided in the corresponding embodiments are networked to obtain a scattering communication voice transmission system, through which full-duplex voice transmission and / or half-duplex voice transmission can be achieved at either end, thereby realizing voice transmission of the scattering communication system in various application scenarios.

[0067] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
