Description

Technical Field

[0001] The present disclosure relates to the field of communication interaction technology, and in particular to a Beidou short message communication method and device. Background Art

[0002] Beidou short message refers to a short message service that uses China's Beidou satellite navigation system to transmit data. Beidou short message can be used to achieve point-to-point or broadcast short message transmission, and supports the transmission of various types of information such as text, numbers, and images.

[0003] Beidou short messages can be applied in many fields, such as emergency communications, agricultural information transmission, logistics tracking, environmental monitoring, etc. It has great application potential in rural areas, remote areas and places with unstable communication networks.

[0004] The Beidou satellite navigation system has global coverage capabilities and can provide a wide range of short message transmission services without geographical restrictions. Moreover, compared with other communication methods, the cost of using Beidou short message services is relatively low, which is economical for some regions or industries with limited resources.

[0005] However, due to the relatively limited bandwidth of Beidou short message service, Beidou short message cannot support large-scale high-speed data transmission in actual applications, which may result in a small number of Chinese characters that can be sent each time (for example, only 49 Chinese characters can be sent at a time). Summary of the Invention

[0030] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0031] From the above background technology records, it can be seen that Beidou short messages still have certain communication capabilities in remote areas and places where the communication network is unstable. However, there are situations where only a few Chinese characters can be sent at a time.

[0032] In one or more embodiments disclosed in the application, by converting the content to be sent into Chinese characters in a predefined character set, it can be encoded using the first encoding method, so that more Chinese characters can be included in a Beidou message sent in a single time.

[0033] Furthermore, this method can reduce the number of messages that need to be sent when sending content with the same Chinese characters, thereby helping to make the interaction between terminals smoother and helping the first terminal to send the content to be sent to the second terminal more efficiently.

[0034] In order to better understand the idea of ​​this disclosure, first combine Figure 1 The schematic diagram of the hardware device used in the short message communication method provided by the present disclosure can also be understood as a short message communication device, such as Figure 1 As shown, the device may include: an RDSS signal receiving module, an RDSS signal transmitting module, an RDSS RF transceiver chip U5 and a BeiDou-3 dedicated baseband chip U6;

[0035] Among them, the RDSS signal transmission module may include: a transmitting antenna L, a power amplifier PA, a low noise amplifier LNA1, a first filter U1 and an attenuator U2. The signal output end of the RDSS RF transceiver chip is connected to the signal input end of the attenuator U2, the signal output end of the attenuator U2 is connected to the signal input end of the first filter U1, the signal output end of the first filter U1 is connected to the signal input end of the low noise amplifier LNA1, the signal output end of the low noise amplifier LNA1 is connected to the signal input end of the power amplifier PA, and the output end of the power amplifier PA is connected to the signal input end of the transmitting antenna L.

[0036] The RDSS signal receiving module may include: a receiving antenna S, a second filter U7, a low noise amplifier LNA2, a low noise amplifier LNA3, a third filter U3 and a fourth filter U4, the signal output end of the receiving antenna S is connected to the signal input end of the second filter U2, the signal output end of the second filter U2 is connected to the signal input end of the low noise amplifier LNA2, the signal output end of the low noise amplifier LNA2 is connected to the signal input end of the third filter U3, the signal output end of the third filter U3 is connected to the signal input end of the low noise amplifier LNA3, the signal output end of the low noise amplifier LNA3 is connected to the signal input end of the fourth filter U4, and the signal output end of the fourth filter U4 is connected to the signal input end of the RDSS RF transceiver chip;

[0038] It can be seen that the short message communication device has the characteristics of high integration, small size and low power consumption. Therefore, it can be widely used in various Beidou communication terminals, including vehicle-mounted, handheld, digital transmission, etc.

[0039] Of course, the short message communication device may further include a processor, and the processor may be connected to each component and may be used to process data generated by each component.

[0040] It should be understood that in actual application scenarios, the specific components that the short message communication device may include can be reasonably changed and set according to actual conditions. Here, only an example of a possible connection diagram of the short message communication device is provided to assist in understanding the idea of ​​the short message communication method disclosed herein.

[0041] Please refer to Figure 2 , which shows the process of an embodiment of the Beidou short message communication method according to the present disclosure. Figure 2 The Beidou short message communication method shown in FIG. 1 can be applied to a first terminal (the first terminal can be understood as a terminal device for sending Beidou short messages), such as Figure 2 As shown, the Beidou short message communication method may include the following steps:

[0042] Step 201 : Based on a predefined character library set of commonly used characters and a first content to be sent, obtain a second content to be sent corresponding to the first content to be sent.

[0043] Wherein, each character in the second content to be sent belongs to a predefined character set.

[0044] Step 202: Obtain at least one Beidou message by encoding the second content to be sent according to the first encoding method.

[0045] The first encoding method is determined based on the number of elements in the predefined character set.

[0046] Step 203: Use the Beidou satellite communication channel to send at least one Beidou message to the second terminal.

[0047] As an example, commonly used characters may be understood as frequently used characters, or may be understood as characters that may be frequently used in specific scenarios.

[0048] For example, in an outdoor adventure interaction scenario, commonly used characters might be used to describe coordinate information, weather conditions, and physical conditions. In a transportation scenario, commonly used characters might be used to describe vehicle status and road conditions. In other words, commonly used characters might vary in different scenarios, and accordingly, the predefined character set for commonly used characters might also vary.

[0049] As an example, the first content to be sent can be understood as the content that needs to be sent out by the user. For example, the user may enter content to report on the current situation. For example, the content entered by the user may be "The first team members, gather at the top of the mountain, pay attention to the current bad weather, the road is slippery, pay attention to safety", where "slippery, bad" may not be characters in the font set. Therefore, the second content to be sent corresponding to the first content to be sent can be "The first team members, gather at the top of the mountain, pay attention to the current bad weather, the road is slippery, pay attention to safety".

[0050] That is, the sentences expressed in the first content to be sent and the second content to be sent have similar meanings, except that the characters in the second content to be sent are all characters in the predefined character library set.

[0051] As an example, the second content to be sent may be encoded using a first encoding method corresponding to a predefined character set, thereby obtaining at least one Beidou message.

[0052] It should be understood that since the number of predefined character sets for commonly used characters is greatly reduced compared to existing Chinese characters, and the first encoding method is determined based on the number of elements in the predefined character set, the result after encoding by the first encoding method requires fewer characters, which helps to include more content in a Beidou message.

[0053] Of course, the specific encoding method selected can be limited according to the actual situation. However, it should be understood that since the total number of items to be encoded is reduced, the memory occupied by each Chinese character after encoding can be less. Therefore, more content can be encoded in the same storage space. That is, a shorter message can include more Chinese characters.

[0054] For example, when encoding 1000 commonly used Chinese characters, the memory occupied by a single Chinese character encoding is reduced, and the maximum length of a single message can be increased. For example: in the related art, 1011000010100001 represents that "啊" is encoded with 16 digits, while in this embodiment, encoding only 1000 commonly used characters can become 0101010101, that is, 10 digits, thus reducing 6 bits; therefore, the maximum length of a single message can be increased. In the related art, a single message can send 49 Chinese characters, while the method of the present disclosure can send 120 Chinese characters.

[0055] As an example, at least one Beidou message can be sent to the second terminal respectively using the Beidou satellite communication channel. And since the content included in each Beidou message increases, compared with the related art, the method of the present disclosure can reduce the number of times of sending short messages in batches, which is conducive to the first terminal sending the content to be sent to the second terminal more efficiently. It can also be understood that it helps to achieve smoother communication between the first terminal and the second terminal.

[0056] As an example, which specific communication channel of which specific Beidou satellite is used can also be limited according to the actual situation, and can be limited according to the actual situation. Here, the specific communication channel selected is not limited.

[0057] It can be seen that in the present disclosure, based on the predefined character library set of common characters and the first content to be sent, the second content to be sent corresponding to the first content to be sent is obtained, where each character in the second content to be sent belongs to the character library set; at least one Beidou message is obtained by encoding the second content to be sent according to the first encoding method, where the first encoding method is used to determine based on the number of elements in the predefined character library set; at least one Beidou message is sent to the second terminal respectively using the Beidou satellite communication channel. And through the method of the present disclosure, the content to be sent is converted into Chinese characters in the predefined character library set, so that it can be encoded using the first encoding method, so that more Chinese characters can be included in a single Beidou message sent.

[0058] Furthermore, when sending the content of the same Chinese characters, this method can reduce the number of messages to be sent, which helps to make the interaction between terminals smoother and also helps the first terminal to send the content to be sent to the second terminal more efficiently.

[0059] In some embodiments, step 101 (obtaining second content to be sent corresponding to the first content to be sent based on a predefined character library set of commonly used characters and the first content to be sent) is further specifically used to:

[0060] Based on the predefined character set and the first content to be sent, determine whether the first content to be sent includes text that does not belong to the character set; when the first content to be sent includes text that does not belong to the predefined character set, update the first content to be sent to obtain the second content to be sent; when the first content to be sent includes text that belongs to the predefined character set, determine that the first content to be sent is the second content to be sent.

[0061] As an example, when the characters in the first content to be sent all belong to the characters in the predefined font set, it can be determined that the first content to be sent meets the requirements of the first encoding, so that the first content to be sent can be determined as the second content to be sent and encoded using the first encoding rule.

[0062] When the text in the first content to be sent includes text that does not belong to the predefined character library set, it indicates that part of the content of the first content to be sent may not meet the requirements of the first encoding. In this way, the first content to be sent can be updated to obtain the second content to be sent. In this way, it can be ensured that the second content to be sent can be encoded using the first encoding to obtain at least one Beidou short message.

[0063] In some embodiments, updating the first content to be sent to obtain the second content to be sent may specifically include:

[0064] Perform contextual semantic analysis on characters that do not belong to the predefined character set;

[0065] Determining, from the predefined character set based on the semantic analysis result, similar commonly used characters corresponding to the characters that do not belong to the predefined character set;

[0066] Based on the determined similar commonly used text, the first content to be sent is updated to obtain the second content to be sent.

[0067] For example, performing contextual semantic analysis on characters that do not belong to the predefined character set can be understood as analyzing the specific meanings expressed by the characters that do not belong to the predefined character set. This helps ensure that the meanings expressed by the updated first content to be sent and the second content to be sent are similar.

[0068] For example, the first content to be sent includes "The destination is at the top of the mountain, please go ahead, the road is slippery and it is easy to fall"; among them, "slippery" and "fall" may not belong to the predefined font set, while "slippery" does belong to the predefined font set. Therefore, after this part of the content is updated, it can be "The destination is at the top of the mountain, please go ahead, the road is slippery, please be careful."

[0069] It should be understood that the first content to be sent may have fewer, the same, or more Chinese characters than the second content to be sent. This is because sentences with similar meanings may have different lengths. For example, "The journey is winding and there are many obstacles" may be updated to: "The journey is winding and there are many obstacles." Or it may be: "The journey is difficult."

[0070] As an example, determining similar commonly used characters from a character set to characters that do not belong to the predefined character set can be understood as performing a contextual semantic analysis on the characters that do not belong to the predefined character set, thereby determining the meaning expressed by the characters that do not belong to the predefined character set in the sentence, which helps to make the similar commonly used characters determined from the predefined character set more accurate.

[0071] In some embodiments, updating the first content to be sent based on the determined similar commonly used text to obtain the second content to be sent may specifically include:

[0072] Display characters that do not belong to the predefined font set and similar commonly used characters;

[0073] In response to receiving the replacement text input by the user, the first content to be sent is updated and the second content to be sent is obtained.

[0074] As an example, by displaying characters that do not belong to the predefined character set and similar commonly used characters, it is convenient for the user to input replacement characters so that the second content to be sent can express a similar meaning to the first content to be sent.

[0075] It should be understood that similar content may include multiple words, that is, there may be multiple words with similar meanings in the predefined character library. Therefore, a character or a word that does not belong to the predefined character library set may correspond to multiple similar commonly used characters, which is conducive to users being able to enter replacement characters more accurately.

[0076] For example, since the replacement text is entered by the user based on displayed similar content, the meaning of the first content to be sent and the second content to be sent can be made more similar. This modification method allows the user to participate in the replacement and also helps ensure that the content subsequently entered by the user can directly meet the predefined font set.

[0077] In some embodiments, the step 103 of “sending at least one BeiDou message to the second terminal” may specifically include:

[0078] Determine the sending order of at least one Beidou message according to the position of the content corresponding to each Beidou message in the second content to be sent; and, according to the determined sending order, after sending a Beidou message, send another Beidou message at an interval of a preset time.

[0079] As an example, by sorting the sending order of at least one Beidou message and sending a Beidou message after a preset time interval, this method of sorting and sending information helps to improve the sending efficiency of Beidou messages.

[0080] As an example, the preset duration may be one minute. Of course, the specific preset duration may be limited according to actual conditions.

[0081] In some embodiments, the above method may further include:

[0082] Generate test confirmation information;

[0083] The detection confirmation information is sent to the second terminal using the Beidou satellite communication channel.

[0084] Here, the second terminal can be used to determine the Beidou message information currently received and sent by the first terminal based on the detection confirmation information, and return the determination result to the first terminal, wherein the determination result is used to indicate the second terminal to the received Beidou message information.

[0085] As an example, by generating detection confirmation information, the current reception status of the second terminal can be known based on the confirmation information fed back by the second terminal. This will help to send Beidou messages more reasonably and ensure that the second terminal can fully receive at least one Beidou message.

[0086] As an example, the first detection confirmation information can be generated after a certain number of Beidou short messages are sent, or after a complete round of Beidou messages are sent. Of course, in the specific implementation method, the specific time for generating the detection confirmation information can be limited according to actual conditions.

[0087] In some embodiments, the method may further include: if the determination result indicates that the second terminal has not completely received at least one Beidou message, determining a time for sending the detection confirmation information next time based on the determination result and the Beidou message sent by the first terminal;

[0088] Before the next time the detection confirmation information is sent, the message information that the second terminal has not received is sent at intervals.

[0089] As an example, the confirmation result can also be understood as a communication success rate. For example, if the first terminal sends 8 messages and the second terminal receives 4 messages, the communication success rate can be 50%.

[0090] It should be understood that the communication success rate can reflect the data loss situation of the Beidou data packet received by the receiving end (second end). The higher the success rate, the less the number of data loss, and the lower the success rate, the more the number of data loss; therefore, when the number of losses is less, it can be determined that the time for sending the detection confirmation information next time is later, and accordingly, when the number of losses is large, it can be determined that the time for sending the detection confirmation time next time is relatively early, so that it can be ensured to a certain extent that the second terminal can accurately receive the Beidou message data sent by the first terminal.

[0091] As an example, after the first detection confirmation message is sent, each subsequent detection confirmation message can be calculated using the following formula:

[0092]

[0093] Where, T max It can be the single round continuous sending time limit of Beidou data packets (which can be understood as the time interval between the next detection confirmation information sent and the last detection confirmation information sent). To round up, T0 is the unit time interval for short message transmission (for example, a short message can be sent once every 1 minute), p is the communication success rate of the receiving end (which can also be understood as the confirmation result returned by the second terminal), and k is a fixed coefficient, and the value of the coefficient k is 3.

[0094] It can be seen from this formula that although the unit time interval of the short message transmission is fixed, since p may change according to the actual transmission situation, the time interval between two adjacent detection confirmation information may be different. That is, the sending of detection confirmation information is related to the current communication success rate. In this way, the number of times the detection confirmation information needs to be sent can be reduced to a certain extent, making the sending of detection confirmation information more reasonable and helping to save communication resources.

[0095] For example, in one possible embodiment, the interval unit time length of the short message round transmission is 1 minute; for example, assuming that the communication success rate p may be 0.5, the single round continuous transmission time limit of the Beidou data packet is two minutes. At this time, the communication success rate is low, and the sent data needs to be confirmed once every two minutes, with two minutes as a round; and when the communication success rate is lower than 0.5, or even lower, the single round continuous transmission time limit of the Beidou data packet is one minute, that is, one minute as a round; each time the sending end sends a Beidou data packet, it needs to determine the order; and when the success rate is 0.9, the communication is successful. When the communication success rate is higher, then after 117 minutes, just need confirm once the data that send; And when the communication success rate is close to 1, then the single round continuous transmission duration limit of Beidou data packet is close to 325 minutes, that is to say, when the communication success rate is very high, just need confirm once the data that send every 325 minutes; Therefore, the transmitting terminal of the present embodiment is higher when the communication success rate is lower, and the frequency that the data that send is confirmed is higher, to prevent a large amount of data loss from occurring in Beidou data packet, and when the communication success is higher, the frequency that the data that send is confirmed is significantly reduced, to ensure Beidou data packet transmission efficiency.

[0096] In some embodiments, the information in the determination result may be generated by:

[0097] Determine the interval frequency of each received Beidou data packet and the number of received Beidou data packets;

[0098] A determination result is generated according to the preset frequency, the determined interval frequency, and the number of received data packets.

[0099] That is, the preset frequency may indicate that the first end has sent a plurality of data packets, and by comparing the plurality of data packets with the received data packets, the success rate may be obtained.

[0100] The determined interval frequency may be variable, which can indicate to a certain extent which data packets and which time periods are received slowly, and can reflect to a certain extent the change in the efficiency of the second terminal in receiving short messages.

[0101] It can be seen that the determination result includes at least the reception success rate and reception efficiency of the second terminal, so that the first terminal can more reasonably send the short message information that has not yet been sent to the second terminal according to the determination result.
