Description

Technical Field

[0001] The present invention relates to the technical field of communication terminals, and in particular to a Beidou short message receiving and sending prediction system and method. Background Art

[0002] The application scenarios of BeiDou-3 short message function are becoming increasingly rich, and its application value in various industries and daily life is gradually becoming prominent. At present, most terminal product designs with BeiDou short message function have met the requirement of 95% sending success rate, which largely guarantees the basic communication needs of users. However, in actual applications, especially in some special user scenarios, the actual use experience of BeiDou short message function is not satisfactory, and the problem of high sending failure rate still exists.

[0003] This problem is particularly prominent in miniaturized mobile terminals, such as mass-market smartphones. Due to the small size and limited internal space of smartphones, multiple wireless communication modes (such as 2G / 3G / 4G / 5G, WIFI, Bluetooth, Beidou short message, Tiantong, etc.) need to be integrated, which undoubtedly increases the difficulty of terminal design. In this context, antenna performance is limited, resulting in the Beidou short message function being prone to sending failures in some scenarios.

[0004] In response to this problem, the commonly provided treatment suggestions mainly include changing to an open venue, adjusting the direction of the phone, waiting for retry and other general instructions. However, these methods often cannot fundamentally solve the problem, nor can they give users enough confidence. In some emergency situations, it is difficult for users to determine the specific cause of the failure to send, which may cause users to feel anxious and dissatisfied. Therefore, it is necessary to design a new Beidou short message sending and receiving prediction system. Summary of the invention

DETAILED DESCRIPTION

[0043] A Beidou short message transmission and reception prediction system and method of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein, while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0046] In a first aspect, the present invention provides a Beidou short message receiving and sending prediction system, such as Figure 1 As shown, a transceiver chip 1 and an interference detection unit 2;

[0047] The interference detection unit 2 is used to collect interference signals in the current environment and send them to the transceiver chip 1; the transceiver chip 1 analyzes the current environment and the signal analysis results in the current environment according to the interference signals.

[0048] Specifically, the transceiver chip 1 is the core component of the system, responsible for sending and receiving Beidou short messages. The chip integrates signal processing and analysis functions, and can perform environmental analysis and signal processing based on the received interference signals. The interference detection unit 2 is used to monitor and collect interference signals in the current environment. These interference signals may come from other radio equipment, natural phenomena or human interference, etc.

[0049] The interference detection unit 2 monitors the electromagnetic signals in the environment in real time, identifies and collects possible interference signals. The collected interference signals are sent to the transceiver chip 1. After receiving the interference signal, the transceiver chip 1 will analyze it to evaluate the communication quality of the current environment. According to the analysis results, the transceiver chip 1 can predict the success rate of short message sending and take corresponding measures, such as adjusting the transmission power, changing the communication frequency or optimizing the encoding method to improve the reliability of communication. After analyzing the interference signal and taking optimization measures (optimization measures may not be performed), the transceiver chip 1 performs the sending and receiving operations of the Beidou short message.

[0050] In one embodiment of the present invention, please refer to Figure 2 , further comprising a radio frequency unit 3, the radio frequency unit 3 comprising a transmitting front-end link 31, a second receiving front-end link 32 and a second signal transceiver device 34;

[0051] The first end of the transmitting front-end link 31 and the first end of the second receiving front-end link 32 are respectively connected to the transceiver chip 1 , and the second ends are connected to the second signal transceiver device 34 through the first RF switch 33 .

[0052] The transmitting front-end link 31 is responsible for amplifying, filtering and modulating the signal from the transceiver chip 1 to make it suitable for radio frequency transmission. The second receiving front-end link 32 is responsible for receiving the radio frequency signal transmitted from the second signal transceiver device 34, and filtering, amplifying and down-converting the signal to convert the signal into a format suitable for processing by the transceiver chip 1. In this embodiment, the second signal transceiver device 34 adopts the second signal transceiver device 34, and those skilled in the art can also use a circularly polarized antenna to receive and transmit signals.

[0053] In one possible embodiment of the present invention, the signal analysis result includes: signal strength, signal quality and transmission success rate.

[0054] Specifically, the interference detection unit 2 includes a first signal transceiver device 22 , and the first signal transceiver device 22 is used to collect and transmit the interference signal to the transceiver chip 1 .

[0055] The interference detection unit 2 further includes a first receiving front-end link 21 , and the first signal transceiver device 22 is connected to the transceiver chip 1 via the first receiving front-end link 21 .

[0056] Specifically, the first signal transceiver 22 mainly collects interference signals and transmits them to the transceiver chip 1. The first receiving front-end link 21 is a link connecting the first signal transceiver 22 and the transceiver chip 1. Its function is to process the collected interference signals, which may include: signal amplification - enhancing the strength of the interference signal for subsequent processing. Filtering - removing unnecessary signal components and retaining only the interference signal. Signal conditioning includes signal matching, conversion, etc. to ensure signal quality.

[0057] Through such a design, external interference signals can be monitored in real time and responded to quickly. Through a dedicated receiving front-end link, interference signals can be optimized and processed. Through the cooperation of the transceiver chip 1 and the interference detection unit 2, it can be better integrated into the existing communication system.

[0058] In another possible embodiment of the present invention, Figure 3As shown, the interference detection unit 2 is provided with a plurality of interference detection units. By deploying the interference detection units 2 at multiple locations, all-round monitoring of the communication system can be achieved, thereby more accurately detecting interference signals from different directions or different frequencies. At the same time, multiple interference detection units 2 can improve the reliability of the system. If one detection unit fails, the other units can still continue to work to ensure the stable operation of the system. By comparing the strength, arrival time or phase difference of the interference signals received by different detection units, the position of the interference source can be more accurately located.

[0059] Specifically, each interference detection unit 2 may be placed at a different location in the communication system, such as a communication node, a base station, or a mobile device. These interference detection units 2 may communicate with each other in some way to share interference information, thereby working together to improve the efficiency of interference processing. Multiple detection units can adopt different response strategies for different types of interference signals, such as adaptive frequency adjustment, dynamic power control, etc.

[0060] In other possible embodiments of the present invention, please refer to Figure 4 , further comprising a second RF switch 23 , through which the first receiving front-end link 21 and the second receiving front-end link 32 are connected to the transceiver chip 1 .

[0061] Specifically, the second RF switch 23 can route the signal of the interference detection unit 2 to different receiving front-end links of the transceiver chip 1 as needed. When necessary, the second RF switch 23 can quickly switch the signal path, such as switching between normal communication mode and interference detection mode. At the same time, the second RF switch 23 can also provide a certain degree of isolation to protect the transceiver chip 1 from being damaged by strong interference signals.

[0062] In this embodiment, the first signal transceiver 22 collects external interference signals. The second RF switch 23 selects to route the interference signal to the first receiving front-end link 21 according to the control signal. The first receiving front-end link 21 processes the received interference signal, such as amplifying and filtering. The processed interference signal is transmitted to the transceiver chip 1 through the second RF switch 23. When interference detection is not required, the second RF switch 23 can switch the receiving path of the transceiver chip 1 back to the second receiving front-end link 32 for normal communication signal processing.

[0063] Similarly, in Figure 4 Based on the embodiment shown in FIG. 1 , a plurality of first signal transceiver devices 22 and first receiving front-end circuits 21 may be provided, such as Figure 5 As shown, and connected to the second RF switch 23.

[0064] In other possible embodiments of the present invention, Figure 6As shown, the first signal transceiver device 22 is provided with at least one, and the first radio frequency switch 33 includes a front radio frequency switch 331 and a rear radio frequency switch 332;

[0065] The first end of the front RF switch 331 is connected to the second signal transceiver 34, the second end is connected to the transmission front-end link 31, and the third end is connected to the first end of the rear RF switch 332;

[0066] The second end of the rear RF switch 332 is connected to the first signal transceiver device 22 , and the third end is connected to the first receiving front-end link 32 .

[0067] Specifically, Figure 6 A scheme for combining RF signals and interference signals is designed to merge the transmitting signal path and the receiving signal path. The combining design scheme needs to support the high power capacity of Beidou transmitting signals and realize the high isolation requirements of the transmitting signal link to the receiving signal link. When analyzing the environment, first traverse the second signal transceiver, the second receiving front-end link 32, the first signal transceiver 22 and the transmitting front-end link 31 respectively to obtain two different signals. Signal demodulation and analysis processing are completed through the transceiver chip 1, and the signal characteristic information is transmitted to the processor 4. When the Beidou short message is sent, the processor 4 transmits the information to be sent to the transceiver chip 1 for modulation and demodulation, and sends it to the second signal transceiver 34 through the transmitting front-end link 31.

[0068] Through the cooperation of the front RF switch 331 and the rear RF switch 332, the normal communication signal and the interference detection signal can be effectively isolated to avoid mutual interference. The system can quickly switch to different working modes as needed, which improves the flexibility and response speed of the system. The dedicated first signal transceiver 22 can more effectively detect and analyze interference signals, thereby taking more effective anti-interference measures.

[0069] Similarly, in Figure 6 Based on the embodiment shown, multiple first signal transceiver devices 22 may be provided, such as Figure 7 As shown, and connected to the rear RF switch 332.

[0070] In another possible embodiment of the present invention, the Beidou short message transmission and reception prediction system also includes a processor 4. When performing environmental analysis, the processor receives a signal analysis result generated by the transceiver chip; when sending a short message signal, the processor selects the information transmission value of the transceiver chip from the signal analysis result.

[0071] Specifically, the processor 4 is responsible for system operation. The transceiver chip 1 is responsible for Beidou short message RF and baseband signal processing, and completes environmental RF signal analysis and processing. The RF unit 3 is responsible for converting electrical signals into RF signals for transmission, or converting received RF signals into electrical signals. The interference detection unit 2 monitors interference signals in the environment, such as electromagnetic interference, noise, etc., and sends the collected interference signal data to the transceiver chip 1.

[0072] Second, please refer to Figure 8 The present invention also provides a Beidou short message sending and receiving prediction method, using the Beidou short message sending and receiving prediction system as described in any one of the above items, comprising the steps of:

[0073] S1, traverse the interference detection unit 2 to obtain an interference signal;

[0074] S2. Analyze and process the interference signal to generate evaluation data;

[0075] S3. Compare the evaluation data with preset data through an algorithm to generate a sending success rate.

[0076] Please refer to Figure 7 , the system will access each interference detection unit 2 and collect the interference signal data detected by them, which may include the frequency, strength, occurrence time, etc. of the interference signal. Next, the system will conduct an in-depth analysis of the collected interference signals, which may include signal identification, signal classification, interference source location, etc. The analysis results will be converted into a series of evaluation data that can reflect the current communication environment and the possible impact on the success rate of Beidou short message transmission and reception.

[0077] Then, specific algorithms (such as machine learning models, statistical analysis, etc.) are used to compare the evaluation data with the preset success rate standards or historical data. Based on the comparison results, the system will predict the Beidou short message sending success rate under the current conditions. Fig. 9 As shown, the system will intuitively display the predicted transmission success rate on the device terminal so that the operator can understand the current communication status. The system will also provide some suggestions or instructions to guide the operator on how to improve the transmission success rate. This may include adjusting the communication frequency, changing the transmission power, optimizing the antenna direction, etc.

[0078] Furthermore, in the step S1, it also includes: traversing the radio frequency unit 3 to obtain the radio frequency signal. The system will also check the status of the radio frequency unit 3, including parameters such as signal strength, frequency, modulation mode, etc., to obtain the current radio frequency signal status. Next, the system will conduct an in-depth analysis of the collected radio frequency signals, which may include signal identification, signal classification, interference source location, etc., and will also compare the radio frequency signal with the interference signal or perform other operations to form an analysis result. The analysis results will also be converted into a series of evaluation data, which can also reflect the status of the current communication environment and the possible impact on the success rate of Beidou short message transmission and reception.

[0079] Furthermore, in the step S2, the analysis process includes signal demodulation, signal comparison, signal quality analysis, spectrum analysis, level analysis and noise analysis.

[0080] Furthermore, in the step S2, the evaluation data includes the signal strength of the radio frequency, the strength of the interference signal and the quality of the signal.

[0081] Specifically, in step S2, useful information is extracted from the received RF signal, such as data packets, modulation type, etc. The analysis performed may include: comparing the current RF signal with a known standard signal or historical signal to identify deviations. Evaluating the clarity and reliability of the signal, including bit error rate, signal-to-noise ratio, etc. Analyzing the frequency distribution of the signal to identify the frequency components of the interfering signal. Measuring the level (power) of the signal to ensure that it is within an appropriate range. Evaluating the noise level in the signal to determine its impact on the communication quality.

[0082] Furthermore, after step S3, the method further includes: displaying the sending success rate and improvement instructions corresponding to improving the sending success rate on the device terminal.

[0083] Further, if it is chosen not to improve the sending success rate, the short message signal is sent directly; if it is chosen to improve the sending success rate, after executing the improvement instruction, steps S1-S3 are repeated.

[0084] Further, the system automatically identifies or manually confirms that the improvement instruction has been executed.

[0085] Furthermore, the evaluation data and algorithm are automatically saved to the processor 4 .

[0086] Specifically, if the improvement measures cannot improve the sending success rate, the system will directly send the short message signal according to the current conditions. If the sending success rate is improved after executing the improvement instructions, the system will re-execute the entire prediction process to ensure the optimal sending conditions. The system can automatically detect whether the improvement instructions have been executed and confirm their effects. The operator can manually confirm that the improvement instructions have been executed to ensure the accuracy of system information and the reliability of operation.

[0087] After the short message is successfully sent, the evaluation data and algorithm results will be automatically saved to the processor 4 for subsequent analysis and optimization. The saved data and algorithm can be used to optimize the entire prediction process, improve the system's adaptability and prediction accuracy. For the complete process, please refer to Fig.10 .

[0088] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
