In PDT/DMR digital transit mode, the forwarding device (including but not limited to the transit station) will forward the voice and data of the terminal to other terminals or other forwarding devices after receiving the voice and data of the terminal. The forwarding process of the forwarding device mainly comprises the following steps: and receiving the information of the terminal, receiving and decoding the information, transmitting and coding the information, and finally forwarding the information. Because receiving decoding and transmitting encoding in the forwarding process can consume certain time, delay can be generated in forwarding; if the information is forwarded once through a plurality of forwarding devices, the forwarding delay of the whole information is further extended.
In PDT/DMR protocol digital mode, fig. 1 is a schematic diagram of digital voice relay, where a voice transmitted by a terminal includes a voice header and a voice superframe (as shown in step a and step e in fig. 1), where the voice header carries voice attribute information, and the voice superframe carries voice and voice attribute information. The forwarding device forwards the voice header and the voice superframe to other terminals or other forwarding devices. Before forwarding, the forwarding device needs to receive, decode, transmit and encode information (step b and step f shown in fig. 1), and then forward the voice header and the voice super frame, where digital signal transmission in fig. 1 refers to wireless transmission, decoding and encoding (step b and step f shown in fig. 1), and particularly refers to channel encoding and decoding and source encoding and decoding in the digital voice communication process. Receiving the decoding and transmitting the encoding (such as the decoding and encoding in fig. 1) may cause a forwarding delay, which may further extend if there are multiple forwarding devices in the network, affecting the timeliness of the voice forwarding. As shown in fig. 1, step b and step f will generate a delay.

In an exemplary embodiment, after the partial content of the voice information is directly forwarded to the destination device without decoding and encoding the partial content of the voice information, the method further includes: and decoding part of the content of the voice information through the forwarding equipment to obtain the decoded voice information.
After receiving the voice information, the forwarding device does not need to receive and decode the voice information and transmit and encode the processed voice information which needs to be sent, and the forwarding device directly forwards the voice information to the destination device after receiving the voice information and then decodes the forwarded voice information, wherein the decoding is mainly used for extracting useful information, for example, the useful information can be ID information of voice attribute information in a voice header, and the information authorization, the information legality confirmation and the like can be confirmed by decoding the forwarded voice information.
In an exemplary embodiment, in a case that the forwarding device receives all contents of voice information sent by a terminal, the directly forwarding all contents of the voice information to a destination device includes: under the condition that the whole content of the voice information is not decoded and the whole content of the voice information is not coded, directly forwarding the whole content of the voice information to a target device; under the condition that the whole content of the voice information is not decoded, directly forwarding the whole content of the voice information to a target device; and under the condition that the whole content of the voice information is not coded, directly forwarding the whole content of the voice information to a target device.

In an exemplary embodiment, receiving, by a forwarding device, part or all of content of voice information transmitted by a terminal includes: receiving a voice superframe sent by the terminal through the forwarding equipment; or receiving the voice header and the voice superframe sent by the terminal through the forwarding device.
It should be noted that the voice information includes a voice header and a voice superframe, the voice header is used to carry voice attribute information, the voice superframe carries voice and voice attribute information, and the voice attribute information in the voice superframe is embedded in the voice without affecting voice communication, and when the voice information is sent, the voice header is transmitted before the voice superframe on the time line.
The following describes a technical solution of the foregoing voice information forwarding method with reference to an exemplary optional embodiment, but the technical solution of the embodiment of the present invention is not limited thereto.
The invention provides an optimized forwarding mechanism through the optional embodiment, thereby achieving the purpose of rapidly forwarding the voice information.
The first optimization mechanism is as follows: the forwarding device does not perform encoding and decoding operations on the received voice information, and as shown in fig. 4, a schematic diagram of a voice superframe in which the forwarding device does not perform encoding and decoding and only transmits voice information in the digital voice information relay includes: 1) The terminal directly sends the voice superframe (as shown in step e of fig. 4) at the beginning of transmission, without sending the voice header; 2) The forwarding device does not perform receiving decoding and transmitting encoding, and directly forwards (as shown in step g and step h of fig. 4). The forwarding process of the voice information is changed into the following steps through the optimization mechanism: when the terminal sends the voice information, the terminal does not send the voice header in the voice information, directly sends the voice superframe in the voice information to the forwarding equipment, and the forwarding equipment directly forwards the received voice information without receiving, decoding, transmitting and encoding the voice information after receiving the voice information. The whole forwarding process omits the transmission of a voice header in the voice information, the receiving and decoding of the voice information and the transmitting and encoding of the voice information in the forwarding process of the forwarding equipment, thereby achieving the purpose of reducing the forwarding delay of the voice information.
In PDT/DMR digital relay communication, the signal codec of the repeater will generate a certain delay, which may cause a significant voice delay in a scenario where multiple repeaters are operating. Comparing fig. 1 and fig. 4, it can be seen that the PDT/DMR digital voice transit method provided by the alternative embodiment of the present invention greatly increases the forwarding speed and reduces the forwarding delay. The Voice superframe Voice contains elements such as an a frame and an embedded Voice header, which are used for replacing the original Voice header.
The second optimization mechanism: the forwarding device forwards the received voice signal to the digital signal and decodes the received voice signal. Fig. 5 is a schematic diagram illustrating that the forwarding device forwards the voice information first and then decodes the voice information in the digital voice information relay.
The forwarding equipment forwards the received voice information and then decodes the voice information. The decoding is mainly used to extract useful information, and may perform post-processing after forwarding the speech signal according to the useful information (for example, ID information in speech attribute information included in a speech header), and verify the validity and other attributes of the forwarded speech information.
In PDT/DMR digital relay communication, the signal codec of the repeater will generate a certain delay, which may cause a significant voice delay in a scenario where multiple repeaters are operating. Comparing fig. 1 and fig. 5, it can be seen that the PDT/DMR digital voice transit method provided by the alternative embodiment of the present invention greatly increases the forwarding speed and reduces the forwarding delay. Meanwhile, the decoding processing during the transfer of the PDT/DMR digital signal in FIG. 1 is reserved, (it should be noted that the encoding can also be reserved if necessary), and the decoding processing is arranged after the transfer, so that the transfer speed of the transfer device is not influenced, and the transfer delay of the digital voice information is reduced.
According to the optional embodiment of the invention, through the forwarding mechanism that the forwarding device does not encode and decode and only sends the voice superframe of the voice information or the forwarding device forwards the received voice signal first and then decodes the received voice signal, the signal forwarding of the voice information in PDT/DMR digital forwarding communication is advanced to the front of the signal encoding and decoding of the voice information, and the forwarding timeliness is ensured, so that the purpose of reducing the forwarding delay of the digital voice information is achieved, and the effect of reducing the voice information delay is obvious under the condition that a plurality of forwarding devices exist.
Fig. 6 is a flowchart (two) of a data forwarding method according to an embodiment of the present invention, and as shown in fig. 6, the flowchart includes the following steps:
step S602: after the forwarding equipment receives the data of the burst structure, analyzing the data;
step S604: and under the condition that a target field exists in the analyzed data, forwarding the data to a destination device corresponding to the data, wherein the target field is a field predetermined by the forwarding device and a sending end of the data.
Through the steps, after the forwarding equipment receives the data of the burst structure, the data is analyzed; and under the condition that a target field exists in the analyzed data, forwarding the data to a target device corresponding to the data, wherein the target field is a field predetermined by the forwarding device and a sending end of the data, that is, whether the target field exists in the data is analyzed, and if the target field exists, the data is forwarded to the target device corresponding to the data, so that the problems that the receiving of the data of the burst structure is to be completed, and then useful information is extracted for forwarding judgment, so that certain time is consumed, the forwarding of voice information is delayed and the like are caused can be solved, and the forwarding efficiency of the voice information is improved.
In an exemplary embodiment, when the target field includes a data type field, the data type field is parsed into the data, and the data type field meets a preset condition, and the data is forwarded to a destination device corresponding to the data; and under the condition that the target field comprises a color code field, analyzing the color code field in the data, wherein the color code field meets a preset condition, and forwarding the data to a target device corresponding to the data.
In an exemplary embodiment, before forwarding the data to a destination device corresponding to the data, the method further includes: determining that the data type field meets the preset condition by the following steps: determining that the data type field meets a preset condition under the condition that the value of the data type field is determined to be a preset first target value; and/or determining that the color code field meets a preset condition by: and under the condition that the value of the color code field is determined to be a preset second target value, determining that the color code field meets a preset condition.
The following describes a technical solution of the foregoing forwarding method for voice information with reference to an exemplary optional embodiment, but the technical solution of the embodiment of the present invention is not limited thereto.
The optional embodiment of the invention provides an optimized forwarding mechanism, thereby achieving the purpose of quickly forwarding and judging the data of the burst structure.
The third optimization mechanism: the forwarding device decodes the data part information of the burst structure and makes a decision of forwarding quickly in advance.
In PDT/DMR digital communications, the air interface frame format is performed in burst (PDU) format. For example, a generic burst structure, each burst includes 27.5 ms of data over the air interface, i.e., 264bits. In the burst of voice forwarding decision, the existing communication technology needs the forwarding device to complete receiving 264bits of data, then extract useful information (such as ID information in the voice header LC) and make forwarding decision.
But part of the information in the burst is a component in the 264bits, but it can be decoded in advance without receiving the 264bits completely, e.g. DATA _ TYPE, CC (color code), etc. in the burst.
Examples may be given of: the DATA _ TYPE is located in the first 166bits of the 264bits. The DATA _ TYPE to be forwarded is defined first, so that in the call, the forwarding device only needs to solve the DATA _ TYPE, and can make a quick forwarding judgment in advance. When the forwarding device finishes receiving the first 166bits of the 264bits, it can extract DATA _ TYPE for forwarding decision, as shown in table one below, which can save the forwarding decision time of 98bits (about 37%) at least.
| 98bits | 10bits | 48bits | 10bits | 98bits |
According to the optional embodiment of the invention, after the forwarding equipment receives the data of the burst structure, the data is analyzed; and under the condition that a target field exists in the analyzed data, forwarding the data to a destination device corresponding to the data, wherein the target field is a field predetermined by the forwarding device and a sending end of the data, so that the problems that a certain time is consumed, the forwarding of voice information is delayed and the like due to the fact that useful information is extracted for forwarding judgment when all data of a burst structure is received can be solved, and the forwarding efficiency of the voice information is improved.
In the invention, before forwarding judgment in PDT/DMR digital signal communication mode, 264bits burst does not need to be received, and fast forwarding judgment is carried out according to partial information in burst, thereby improving the forwarding efficiency of voice information.
