For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The Mobile terminal according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal.
The following describes embodiments of the present application in detail.
Referring to fig. 1, fig. 1 is a schematic network architecture of a long-range BLE network disclosed in an embodiment of the present application, where the long-range BLE network includes BLE nodes such as a first mobile terminal, a second mobile terminal, a third mobile terminal, and a BLE gateway. The BLE node in the long-distance BLE network modulates the physical layer (PHY), so the BLE node can also be used for different protocols and different network architectures (such as Mesh, Star, point-to-point, and the like).
Long range (Lora), also called long distance, is a low power consumption local area network wireless standard (IEEE 802.15.4 g). Bluetooth Low Energy (BLE), also called Bluetooth Low Energy, is a personal area network technology designed and sold by the Bluetooth special interest group. The BLE node may communicate with other BLE nodes through the BLE gateway or other relay-enabled BLE node pairs. The communication distance of the BLE node is generally several kilometers to tens of kilometers, and the communication distance of the BLE node is longer compared with the communication distance of the classic Bluetooth communication and the WiFi communication.
The BLE node may include a BLE module (e.g., a BLE chip) that supports a data transmission rate of 250kbps, 500kbps, 1Mbps, and 2 Mbps. The BLE chip can support not only a spread spectrum modulation mode, but also other modulation modes of a plurality of standards, such as Frequency-shift Keying (FSK)/Gaussian Frequency-shift Keying (GFSK), can be switched with each other, and not only can realize the remote modulation capability, but also can use the standard FSK or binary On-Off Keying (OOK) modulation technology. The BLE node may be any mobile terminal including a BLE module, such as a cell phone, a wearable device (e.g., a smart bracelet, a smart watch, a smart headset, etc.), a tablet, etc.
Mesh networking can be performed between the BLE nodes, the first mobile terminal and the second mobile terminal can join the same group, and the BLE nodes joining the same group can have a priority relay right. Devices in the Mesh network can perform multi-hop transmission in the Mesh network.
The first mobile terminal and the second mobile terminal can directly establish a bluetooth communication channel, and the first mobile terminal can also establish the bluetooth communication channel through a BLE gateway and/or other BLE nodes. Generally speaking, when the distance between the first mobile terminal and the second mobile terminal is less than the maximum distance allowing bluetooth connection, if the first mobile terminal needs to perform bluetooth communication with the second mobile terminal, the first mobile terminal and the second mobile terminal can directly establish a bluetooth communication channel; when the distance between the first mobile terminal and the second mobile terminal is greater than the maximum distance allowing Bluetooth connection, if the first mobile terminal needs to perform Bluetooth communication with the second mobile terminal, the first mobile terminal and the second mobile terminal can establish a Bluetooth communication channel through a BLE gateway and/or other BLE nodes.
In this application embodiment, when using BLE network to carry out voice call, can be when BLE network is relatively poor quick transmission retransmission data package to promote the voice call effect of BLE network.
Based on the network architecture shown in fig. 1, the embodiment of the present application discloses a data packet retransmission method. Referring to fig. 2, fig. 2 is a flowchart illustrating a data packet retransmission method according to an embodiment of the present application, and as shown in fig. 2, the data packet retransmission method includes the following steps.
201, when a first mobile terminal and a second mobile terminal perform a voice call, if the first mobile terminal fails to transmit a first voice data packet to the second mobile terminal, the first mobile terminal extracts at least one first voice keyword from the first voice data packet.
In this embodiment of the application, the first mobile terminal and the second mobile terminal both belong to a BLE node in a long-distance BLE network. The first mobile terminal and the second mobile terminal may be connected through a BLE gateway, may be connected through another BLE node having a relay function, and may be directly connected. Both the first mobile terminal and the second mobile terminal may support the relay function. The first mobile terminal and the second mobile terminal can also perform Mesh networking and join the same group.
When the first mobile terminal needs to perform Bluetooth voice communication with the second mobile terminal, the first mobile terminal and the second mobile terminal both start a Bluetooth low energy function, and the first mobile terminal can establish a communication channel with the second mobile terminal through a long-distance BLE network to realize long-distance voice telephone communication.
When a first mobile terminal needs to perform Bluetooth voice communication with a second mobile terminal, a microphone of the first mobile terminal can collect voice signals input by a user, a voice encoder of the first mobile terminal can sample the input voice signals according to a certain sampling frequency, the sampled signals are encoded, the encoded signals are compressed, and the compressed signals are packaged to obtain a voice data packet. If the BLE networks of the first mobile terminal and the second mobile terminal are poor, packet loss may occur when the first mobile terminal transmits the voice data packet to the second mobile terminal, so that the first mobile terminal fails to transmit the first voice data packet to the second mobile terminal.
The BLE network quality may be determined by a bluetooth Received Signal Strength Indication (RSSI) of the first mobile terminal. For example, if the bluetooth RSSI of the first mobile terminal is lower than-130 dBm, the BLE network is considered to be poor.
In the embodiment of the application, if the first mobile terminal fails to transmit the first voice data packet to the second mobile terminal, the first mobile terminal extracts at least one first voice keyword from the first voice data packet. The first mobile terminal can recognize the text information from the first voice data packet through a voice recognition algorithm, and extracts the key words from the text information. For example, the text message is "i have a break for a moment, and six spots go to XX station", and the keywords include six total voice keywords of "i", "have a break", "a moment", "six spots", "go", "XX station".
202, the first mobile terminal detects whether at least one first voice keyword contains an important keyword.
In the embodiment of the present application, the important keyword may include not only a verb but also a noun such as a person name, a place name, and time. Important keywords may also include some adjectives.
Optionally, the important keyword includes at least one of a verb, a place name keyword, a person name keyword, and a time keyword.
And 203, if the first mobile terminal receives the first target voice keyword, the first mobile terminal generates a first retransmission voice data packet containing the first target voice keyword, and sends the first retransmission voice data packet to the second mobile terminal, wherein the first target voice keyword comprises at least one important keyword in the first voice keyword.
In the embodiment of the application, if the first mobile terminal detects that the at least one first voice keyword contains an important keyword, a first retransmission voice data packet is generated according to the important keyword in the at least one first voice keyword. The voice data packet corresponding to the important keyword in the at least one first voice keyword is smaller than the voice data packet corresponding to the at least one first voice keyword.
For example, the first voice keyword includes "me", "rest", "a moment", "six points", "go", "XX station" for a total of six voice keywords. The important keywords include four speech keywords of "me", "six points", "go", "XX station". Obviously, the voice data packets corresponding to the four voice keywords are smaller than the voice data packets corresponding to the six voice keywords. The information of the important keywords can reflect the content in the first language data packet, and the first target voice keywords can form complete semantics. After receiving the first retransmission voice data packet, the second mobile terminal can acquire key voice information from the first retransmission voice data packet, so that the voice call effect of the BLE network is improved.
In this application embodiment, only transmit the first retransmission voice data package that contains important keyword when retransmitting voice data package, because first retransmission data package obviously will be less than first voice data package, can reduce the size of the retransmission data package of transmission when guaranteeing the important keyword of the voice data package of transmission, can be at the retransmission data package of the quick transmission when BLE network is relatively poor to promote the voice conversation effect of BLE network.
Optionally, the method shown in fig. 2 may further include step 204.
And 204, if not, the first mobile terminal discards the first voice data packet.
In the embodiment of the application, if at least one first voice keyword does not contain an important keyword, it indicates that the first voice data packet does not contain important information, and in order to improve the voice call effect, the first voice data packet may be directly discarded, and the voice data packet waiting for transmission may be directly transmitted.
In the process of voice communication, because voice sent by a user is generally continuous, if the transmission of a voice data packet fails, if retransmission is selected, the voice communication is delayed, if the voice data packet does not contain important keywords, the voice data packet is directly discarded, and then the next voice data packet is transmitted, so that the effect of the voice communication is improved.
Optionally, in step 201, the first mobile terminal extracts at least one first voice keyword from the first voice data packet, which may specifically include the following steps:
(11) the first mobile terminal converts the first voice data packet into first text information;
(12) the first mobile terminal extracts at least one first voice keyword in the first text message.
In this embodiment, the first mobile terminal may convert the first voice data packet into the first text information by using a voice recognition algorithm. The speech recognition algorithm may comprise a neural network algorithm.
Optionally, the first voice data packet is encoded according to a first encoding method, and in step 203, the first mobile terminal generates a first retransmission voice data packet containing a first target voice keyword, including:
(21) the method comprises the steps that a first mobile terminal obtains at least one voice fragment containing a first target voice keyword;
(22) the first mobile terminal splices at least one voice segment to obtain a spliced voice segment;
(23) and the first mobile terminal encodes the spliced voice fragments by adopting a second encoding mode to obtain a first retransmission voice data packet, wherein the encoding code rate corresponding to the second encoding mode is smaller than that corresponding to the first encoding mode.
In the embodiment of the application, each voice keyword corresponds to one voice segment. The first mobile terminal can obtain at least one voice segment corresponding to the first target voice keyword. For example, if there are 4 first target voice keywords, the first mobile terminal may obtain 4 voice segments corresponding to the 4 first target voice keywords.
The voice segment is a segment into which a voice signal collected by a microphone of the first mobile terminal is divided. For example, the speech signal lasts for 7 seconds, and the six keywords are "me", "rest", "one", "six points", "go", "XX station", where "me" is a 0-0.5 second speech segment in the speech signal, "rest" is a 0.5-1.5 second speech segment in the speech signal, "one" is a 1.5-2.5 second speech segment in the speech signal, "six points" is a 3-4 second speech segment in the speech signal, "go" is a 4-4.5 second speech segment in the speech signal, and "XX station" is a 4.5-7 second speech segment in the speech signal.
The first mobile terminal can acquire four key voice fragments of a voice fragment of 0-0.5 second, a voice fragment of 3-4 second, a voice fragment of 4-4.5 second and a voice fragment of 4.5-7 second in the voice signal, and the four key voice fragments are spliced according to the time sequence of the four voice fragments in the voice signal to obtain a spliced voice fragment, wherein voice keywords in the spliced voice fragment comprise 'I', 'six points', 'go', 'XX station'.
The speech signal needs to be encoded before transmission. Generally, the lower the coding rate of audio coding, the smaller the encoded voice data packet, and the smaller the occupied storage space. Because the coding rate corresponding to the second coding mode is smaller than the coding rate corresponding to the first coding mode, the size of the first retransmission data packet is smaller than the size of the first voice data packet. The size of the retransmission data packet transmitted can be reduced while the voice data packet transmitted is guaranteed to include important keywords, and the retransmission data packet can be rapidly transmitted when the BLE network is poor, so that the voice communication effect of the BLE network is improved.
Referring to fig. 3, fig. 3 is a schematic flow chart of another data packet retransmission method disclosed in the embodiment of the present application, and fig. 3 is obtained by further optimizing on the basis of fig. 2. As shown in fig. 3, the data packet retransmission method includes the following steps.
301, when the first mobile terminal performs a voice call with the second mobile terminal, if the first mobile terminal fails to transmit the first voice data packet to the second mobile terminal, the first mobile terminal extracts at least one first voice keyword from the first voice data packet.
302, the first mobile terminal detects whether at least one first voice keyword contains an important keyword.
303, if yes, the first mobile station generates a first retransmission voice data packet containing a first target voice keyword, and sends the first retransmission voice data packet to the second mobile station, where the first target voice keyword includes an important keyword in at least one first voice keyword.
For specific implementation of steps 301 to 303 in this embodiment, reference may be made to detailed descriptions of steps 201 to 203 shown in fig. 2, which is not described herein again.
304, in the voice communication process, if the number of times that the first mobile terminal retransmits the data packets to the second mobile terminal reaches the preset number threshold, the first mobile terminal acquires a second voice data packet to be transmitted to the second mobile terminal.
In the embodiment of the present application, the preset number threshold may be preset and stored in a memory (e.g., a non-volatile memory) of the mobile terminal. For example, the preset number threshold may be set to 10. The data packets retransmitted by the first mobile terminal to the second mobile terminal may be the same data packet or different data packets.
The first mobile terminal extracts 305 at least one second voice keyword from the second voice data packet.
306, the first mobile terminal detects whether the at least one second voice keyword contains an important keyword.
307, if the at least one second voice keyword includes an important keyword, the first mobile terminal generates a third voice data packet including a second target voice keyword, and sends the third voice data packet to the second mobile terminal, where the second target voice keyword includes the important keyword of the at least one second voice keyword.
Optionally, fig. 3 may further include step 308.
308, if the at least one second voice keyword does not include an important keyword, the first mobile terminal discards the second voice data packet.
In the embodiment of the application, when the number of the data packets retransmitted to the second mobile terminal by the first mobile terminal reaches the preset number threshold, it indicates that the current voice call quality is poor, so as to avoid the situation of voice retransmission. And when the voice data packet is transmitted subsequently, performing semantic analysis on the voice data packet to be transmitted in advance, if the voice data packet to be transmitted contains important keywords, regenerating a smaller data packet for transmission, and if the voice data packet does not contain the important keywords, directly discarding the second voice data packet. According to the embodiment of the application, when the current voice call quality is judged to be poor, semantic analysis can be performed in advance, retransmission after first transmission is avoided, the transmission time length of the second voice data packet is saved, and the voice call effect is improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating another data packet retransmission method according to an embodiment of the present application, and fig. 4 is obtained by further optimizing on the basis of fig. 2. As shown in fig. 4, the data packet retransmission method includes the following steps.
401, when the first mobile terminal performs a voice call with the second mobile terminal, if the first mobile terminal fails to transmit the first voice data packet to the second mobile terminal, the first mobile terminal detects whether the RSSI is smaller than a preset signal strength threshold.
In the embodiment of the application, when the first mobile terminal fails to transmit the first voice data packet to the second mobile terminal, the keyword extraction and the keyword analysis are not directly performed, but the RSSI is detected first, and whether the keyword extraction and the keyword analysis are performed or the first voice data packet is directly retransmitted is determined according to the detected RSSI. The Bluetooth RSSI is acquired, so that the first mobile terminal can judge the quality of the current call quality more accurately.
402, if the value is less than the first threshold value, the first mobile terminal extracts at least one first voice keyword from the first voice data packet.
403, the first mobile terminal detects whether at least one first voice keyword contains an important keyword.
404, if yes, the first mobile station generates a first retransmission voice data packet containing a first target voice keyword, and sends the first retransmission voice data packet to the second mobile station, where the first target voice keyword includes an important keyword among at least one first voice keyword.
For a specific embodiment of steps 402 to 404, refer to detailed descriptions of steps 201 to 203 shown in fig. 2, which are not described herein again.
Optionally, if the RSSI is greater than or equal to the preset signal strength threshold, the first mobile terminal continues to transmit the first voice data packet to the second mobile terminal.
In the embodiment of the application, if the RSSI is greater than or equal to the preset signal strength threshold, it indicates that the quality of the bluetooth communication channel established between the first mobile terminal and the second mobile terminal is better, and retransmission is not required after processing, i.e. keyword extraction and keyword analysis are not performed, and the first voice data packet is directly retransmitted. According to the embodiment of the application, the first voice data packet can be directly retransmitted when the current Bluetooth RSSI is high, voice keyword extraction and keyword analysis are not needed, the time for the first mobile terminal to send the first voice data packet to the second mobile terminal can be shortened, and therefore the voice call effect is improved.
The above description has introduced the solution of the embodiment of the present application mainly from the perspective of the method-side implementation process. It is understood that the mobile terminal includes hardware structures and/or software modules for performing the respective functions in order to implement the above-described functions.

The integrated unit can be realized in a form of hardware, and can also be realized in a form of a software functional unit.
