[0041] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0043] In order to solve the problem in related technologies that power voice data cannot be carried, resulting in the power industry being unable to conduct emergency and command and dispatch through power voice data, the present application provides a method, device, electronic device and storage medium for carrying power voice information to achieve the carrying of power voice data and ensure its security.

[0044] See also Figure 1 , Figure 1 This is a flow chart of a method for carrying power voice information provided in an embodiment of the present application. Figure 1 As shown, the method for carrying power voice information may include the following steps:

[0045] Step S101: Acquire power voice information to be carried, wherein the power voice information includes power voice data and a key information header corresponding to the power voice data.

[0046] It should be noted that the method for carrying electric power voice information provided in the embodiment of the present application can be applied to the sending end, which can be a user terminal or a base station, and the embodiment of the present application does not make any specific limitations.

[0047] Specifically, the power voice information may include power voice data and a key information header. The power voice data may be compressed by a vocoder and encrypted with the key information. The vocoder may have a native compression data rate of 2.4K or 2.2K, without forward error correction (FEC). The key information header may include key information used to encrypt the power voice data. This key information may be 96 bits or another number of bits, and may be set based on actual needs.

[0048] Step S102: Segment the power voice data and the key information header respectively to obtain multiple compressed voice segments and multiple key information segments.

[0049] After the transmitter obtains the electric power voice data, it can segment the electric power voice data to obtain multiple compressed voice segments. For ease of understanding, the original compressed data rate of the vocoder is 2.4K as an example. Since one time slot in the EPDT protocol occupies 30ms, 60ms of voice compression data can be sent in one time slot (that is, 60ms of voice compression data is sent in one time slot). Here, the 60ms of voice compression data can be obtained three times, once every 20ms. Each compressed voice segment obtained corresponds to 48 bits of data, so 60ms corresponds to a total of 144 bits of data. Since the net load that can be carried by a time slot in the EPDT protocol is 192 bits, in addition to carrying 144 bits of voice compression data (such as Figure 2 In addition to the compressed speech segments VS0, VS1 and VS2 in the 48-bit area, there are 48 bits of custom area left for users to customize. Figure 2 By the above method, each 60ms voice compression data in the electric power voice data can be segmented to obtain multiple compressed voice segments.

[0050] It should be noted that when other vocoders are used, the sampling rate of the vocoder changes, and the voice compression data sent in each time slot also changes accordingly. Then the effective number of bits of the compressed voice segment is different, and the reserved user-defined area is also different. However, the method of using voice superframes to carry compressed voice segments is within the scope of protection of this article. In the EPDT protocol, each data burst can include two 192-bit payload areas, a 48-bit synchronization area or embedded signaling area, a 16-bit time slot status area divided into two parts, located on both sides of the synchronization area, and two protection areas. Its structure is as follows Figure 3 The total duration of each data burst is 30ms, of which the effective 448-bit content lasts for 28ms, which can carry a 192-bit net payload.

[0051] At the same time, after obtaining the key information header corresponding to the power voice data, the transmitter can also segment the key information header to obtain multiple key information segments. For ease of understanding, here we use 96 bits of key information as an example. When segmenting, the 96 bits of key information can be divided into four 24-bit key information segments, or six 16-bit key information segments, etc. In this way, the key information header can be segmented to obtain multiple key information segments.

[0052] Step S103: Carry multiple compressed voice segments and multiple key information segments to the first area of ​​each voice burst according to the preset carrying rules, and channel encode the information in the first area of ​​each voice burst, and send it to the receiving end in the form of a voice superframe, so that the receiving end can parse the power voice data and key information header from the voice superframe, and decrypt the power voice data based on the key information header, wherein each voice superframe includes multiple voice bursts.

[0053] Specifically, the above-mentioned voice superframe may include multiple voice bursts, and the structure of the voice burst here is similar to Figure 2The data bursts in the same structure can both carry a 192-bit payload. The difference between the two is that the two 192-bit payload areas of the voice burst carry compressed voice segments and custom content, while the two 192-bit payload areas of the data burst carry pure data content. The first area here can refer to the payload area of ​​the voice burst or other areas of the voice burst, and this application does not make specific restrictions.

[0054] After obtaining the voice superframe, the transmitting end may send the voice superframe to the receiving end. In this way, the receiving end may parse the power voice data and the key information header from the voice superframe and decrypt the power voice data based on the key information header.

[0055] Through the above method, the compressed voice segment and the key information segment can be carried to the first area of ​​the voice burst, and then the voice superframe can be used to carry the power voice data and the key information header to realize the transmission of the power voice data, so that the power industry can carry out emergency and command and dispatch through the power voice data; at the same time, it also enables the receiving end to reorganize the key information header after receiving the key information segment, and use the key information header to decrypt the transmitted power voice data to realize the secure transmission of the power voice data.

[0056] In an optional embodiment, the step S103 of carrying the multiple compressed voice segments and the multiple key information segments to the first area of ​​each voice burst according to a preset carrying rule includes:

[0057] sequentially selecting a first preset number of compressed speech segments from the plurality of compressed speech segments, and carrying the first preset number of compressed speech segments selected each time to the first area of ​​each speech burst; and

[0058] A second preset number of key information segments are selected in sequence from the multiple key information segments, and the second preset number of key information segments selected each time are carried to the first area of ​​the first voice burst, wherein the first voice burst is a specified part of the voice burst or the entire voice burst in the voice superframe, the first area is the effective payload area of ​​the voice burst, and the total length of the first preset number of compressed voice segments and the second preset number of key information segments is less than the length of the net payload allowed to be carried by the first voice burst.

[0059] Specifically, the first preset number and the second preset number can be set based on actual needs and are not specifically limited herein. The first voice burst refers to a voice burst carrying a key information segment, which can be a designated portion of a voice burst or the entire voice burst within a voice superframe. The total length of the first preset number of compressed voice segments and the second preset number of key information segments is less than the payload length allowed for the first voice burst. For example, when the payload length allowed for the first voice burst is 192 bits, the total length of the first preset number of compressed voice segments and the second preset number of key information segments is less than 192 bits. As an alternative embodiment, the first preset number can be set to three and the second preset number to one, meaning that each voice burst carries three compressed voice segments and one key information segment. The key information segment can be carried in the custom area and channel-coded along with the compressed voice segments to form a voice superframe and then transmitted to the receiving end. In this way, the key information segment is transmitted after channel coding, providing enhanced security.

[0060] The transmitter can sequentially select a first preset number of compressed speech segments from the plurality of compressed speech segments, and then carry the first preset number of compressed speech segments selected each time into the payload area (i.e., the first area) of each voice burst. Furthermore, the transmitter can sequentially select a second preset number of key information segments from the plurality of key information segments, and then carry the second preset number of key information segments selected each time into the payload area of ​​the first voice burst. The transmitter can then perform channel coding on the information in the payload area of ​​each voice burst using an encoder and an interleaver to generate a voice burst, thereby forming a voice superframe.

[0061] This allows the power voice data and key information header to be carried in the voice superframe for transmission, enabling the transmission and encryption of power voice data between the transmitter and receiver. Furthermore, because each key information segment in the key information header is also channel-coded, the key information is more reliable and more secure.

[0062] In an optional embodiment, the voice superframe includes six voice bursts, wherein the first voice burst is the second voice burst to the fifth semantic burst in the voice superframe, or the first voice burst is the first voice burst to the sixth semantic burst in the voice superframe, and the first area of ​​the first voice burst includes a first preset number of compressed voice segments and a second preset number of key information segments.

[0063] Specifically, a speech superframe may include six speech bursts (occupying a total of 360ms), which are represented by speech burst A, speech burst B, speech burst C, speech burst D, speech burst E, and speech burst F, respectively. Figure 4As shown in the figure, voice burst A carries voice synchronization information (SYNC), while voice bursts B through F carry embedded signaling. Before sending voice burst A, a data burst can be sent. This data burst carries the data synchronization information SYNC, a voice header (Line of Contact, LC), and a key information header (Payload Integrity Check, PI). During a voice call, voice superframes can be used as the basic transmission unit and sent continuously.

[0064] As an optional implementation, the multiple key information segments of the key information header can be located in the first area from the second speech burst to the fifth semantic burst of the speech superframe, that is, in the first area from speech burst B to speech burst E. In this way, the first area from speech burst B to speech burst E is as follows: Figure 5 For example, assuming that the key information header is 96 bits, the 96-bit key information header can be divided into four key information segments, each of which is 24 bits and is respectively set in the custom area in the first area of ​​voice burst B to voice burst E.

[0065] As another optional embodiment, the multiple key information segments of the key information header are located in the first area from the first speech burst to the sixth semantic burst of the voice superframe, that is, in the first area from speech burst A to speech burst F. In this way, the first area from speech burst A to speech burst F is also Figure 5 For example, assuming that the key information header is 96 bits, the 96-bit key information header can be divided into 6 key information segments, each of which is 16 bits and is respectively set in the custom area in the first area of ​​voice burst A to voice burst F.

[0066] In this embodiment, the key information segment undergoes channel coding along with the compressed voice segment, enhancing key protection and minimizing decryption errors. Furthermore, by carrying the key information segment in the first region of the voice burst, there's no need for additional control frames to carry the key information. This saves air interface resources and control logic, making implementation easier and truly addressing user pain points and difficulties.

[0067] In an optional embodiment, the step S103 of performing channel coding on the information in the first region of each voice burst and sending the information to the receiving end in the form of a voice superframe includes:

[0068] Encoding the information in the first region of each speech burst using an encoder to obtain encoded data corresponding to each speech burst, wherein a length of the encoded data corresponding to each speech burst is greater than a length of the information in the first region of each speech burst;

[0069] The coded data corresponding to each voice burst is interleaved by an interleaver to form a voice superframe, and the voice superframe is sent to the receiving end.

[0070] Specifically, the channel coding process of the information in the first region of each speech burst can be as follows: Figure 6 As shown, an encoder is first used to encode the information in the first region of each speech burst to obtain coded data corresponding to each speech burst, and then an interleaver is used to interleave the coded data corresponding to each speech burst to form a speech superframe.

[0071] It should be noted that the encoding process will double the check bits. For example, after 192 bits of data are encoded by the encoder, 384 bits of encoded data will be obtained. Therefore, this can ensure the reliable transmission of voice, and the transmission distance will be greatly improved, which is more conducive to use in emergency environments.

[0072] In this embodiment, since each key information segment is concatenated with a first predetermined number of compressed voice segments before being encoded and interleaved, the key information's check bits are expanded, effectively addressing uncertainties in wireless transmission paths and minimizing decryption errors. Furthermore, this method can be used for both end-to-end encryption and over-the-air encryption, enhancing the reliability of both end-to-end and over-the-air transmissions.

[0073] In an optional embodiment, before performing channel coding on the information in the first region of each voice burst and sending the information in the form of a voice superframe to the receiving end in step S103, the method further includes:

[0074] Obtaining a voice header corresponding to the power voice data and segmenting the voice header to obtain multiple control information segments;

[0075] A third preset number of control information segments are selected in sequence from multiple control information segments, and the third preset number of control information segments selected each time are carried to the second area of ​​the second voice burst, wherein the second voice burst is a specified portion of the voice burst in the voice superframe, the second area is an embedded signaling area of ​​the voice burst, and the total length of the third preset number of control information segments is less than the length of the embedded signaling allowed to be carried by the second voice burst.

[0076] Specifically, the transmitting end can also obtain the voice header corresponding to the power voice data and segment the voice header to obtain multiple control information segments. The transmitting end then sequentially selects a third preset number of control information segments from the multiple control information segments and carries each selected third preset number of control information segments into the embedded signaling area (i.e., the second area) of the second voice burst. The voice header can include various control information such as call type (single call / group call, emergency call / non-emergency call, etc.), source address, and destination address. Its length can be set based on actual needs. The second voice burst carries the control information segment, which can be a specified portion of the voice burst in the voice superframe. The third preset number can be set based on actual needs and is not specifically limited here.

[0077] In this way, a terminal that accesses later can also parse the voice header from the voice superframe after receiving the voice superframe, and use it to confirm whether it is power voice data sent to itself. If so, it parses the power voice data from the voice superframe; if not, it discards it.

[0078] In an optional embodiment, the voice superframe includes six voice bursts, wherein the second voice burst is the second voice burst to the fifth semantic burst of the voice superframe, and the second area of ​​the second voice burst includes a third preset number of control information segments.

[0079] Specifically, a speech superframe may include six speech bursts (occupying a total of 360ms), which are represented by speech burst A, speech burst B, speech burst C, speech burst D, speech burst E, and speech burst F, respectively. Figure 5 As shown in the figure, voice burst A carries synchronization information, while voice bursts B through F carry embedded signaling. During a voice call, voice superframes can be used as the basic transmission unit and sent continuously.

[0080] The multiple control information segments of the voice header can be located in the second region from the second voice burst to the fifth semantic burst of the voice superframe, that is, in the second region from voice burst B to voice burst E. In this way, a terminal that accesses later can also parse the voice header from the second region from voice burst B to voice burst E after receiving the voice superframe and determine whether it is power voice data sent to itself. If so, it parses the power voice data from the voice superframe; otherwise, it discards the data.

[0081] In an optional embodiment, before performing channel coding on the information in the first region of each voice burst and sending the information in the form of a voice superframe to the receiving end in step S103, the method further includes:

[0082] The voice header and key information header are sent to the receiving end in the form of a data frame, so that the receiving end determines whether to receive the voice superframe based on the voice header, and if it is determined that the voice superframe is received, decrypts the compressed voice segment in the voice superframe based on the key information header.

[0083] Specifically, before sending the voice superframe, the sending end can first send the voice header and the key information header to the receiving end in the form of a data frame. In this way, before receiving the voice superframe, the receiving end can directly confirm whether the voice superframe is the power voice data sent to itself based on the voice header. If it is confirmed that the voice superframe is the power voice data sent to itself, the voice superframe is received, and the power voice data is parsed from the voice superframe, and then decrypted using the key information header; if it is confirmed that the voice superframe is not the power voice data sent to itself, the voice superframe is discarded.

[0084] In the above manner, the receiving end can promptly receive and decrypt the electric power voice data sent to itself based on the voice header and key information header in the data frame, ensuring that the electric power voice data can be received normally.
