[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "first," "second," etc., used in this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps, units, or modules is not necessarily limited to those explicitly listed, but may include other steps, units, or modules not explicitly listed or inherent to such processes, methods, products, or devices.

[0028] Figure 1 This is one of the flowcharts illustrating the remote configuration method for the BeiDou short message terminal provided by this invention, such as... Figure 1 As shown, the method includes steps 110, 120, 130, and 140. The executing entity of the remote configuration method for the BeiDou short message terminal provided by this invention can be the BeiDou short message terminal itself. Unless otherwise specified, subsequent embodiments will use the BeiDou short message terminal as an example for explanation.

[0029] Step 110: Obtain initial short message information, add monitoring identification information to the initial short message information, and generate the first short message.

[0030] Specifically, the remote configuration method for the BeiDou short message terminal provided in this embodiment of the invention is executed by a remote configuration device for the BeiDou short message terminal. This device can be implemented in software, such as a remote configuration program for the BeiDou short message terminal running on a computer; or it can be implemented in hardware, such as a computer or server executing the remote configuration method for the BeiDou short message terminal.

[0031] The remote configuration method for Beidou short message terminals provided in this embodiment of the invention is suitable for short message industry customers who collect IoT data. Based on the data analysis capabilities of the industry customer platform and the analysis of performance data from daily communication processes, the method automatically calculates the terminal's configuration parameters and sends them to the terminal via short messages, thereby enabling remote configuration of the short message terminal.

[0032] The BeiDou short message terminal is a hardware device deployed at application sites (such as ocean-going fishing vessels, uninhabited forest areas, and geological monitoring points). It is the "outpost" of the entire system, responsible for data collection and command execution.

[0033] Industry short message platforms are typically deployed as server systems in city data centers or the cloud. They serve as the "brain" of the entire system, responsible for aggregating, analyzing, and making decisions based on massive amounts of data.

[0034] Figure 2This is a schematic diagram of the remote configuration method for the BeiDou short message terminal provided by the present invention, as shown below. Figure 2 As shown, the BeiDou short message terminal establishes an air link with the BeiDou-3 satellite through a short message transceiver antenna, and uses the BeiDou-3 short message communication chip to receive and send short messages. The industry short message platform interacts with the BeiDou short message ground system through an industry data interface module. Furthermore, the BeiDou short message terminal configures parameters such as transmission power and communication frequency through a device configuration module; it parses the received short message content into terminal configuration commands through a remote command parsing module and sends them to the device configuration module; and it operates through a power supply module.

[0035] Initial short message information refers to the original business payload that the terminal needs to upload to the industry short message platform. In this embodiment of the invention, the Beidou short message terminal acquires raw data collected in real time by environmental sensors (such as temperature, humidity, air pressure, water level, or geographic location sensors) through its integrated IoT data acquisition module. This raw data is then formatted to form initial short message information.

[0036] Monitoring identification information refers to a non-service data field generated by the BeiDou short message terminal and appended to the initial short message service payload, used to characterize the data transmission status. In this embodiment of the invention, the monitoring identification information includes a transmission sequence number and a transmission timestamp.

[0037] Figure 3 This is a flowchart illustrating the specific implementation of the remote configuration method for the BeiDou short message terminal provided by this invention. Figure 3 As shown, the remote configuration method for the BeiDou short message terminal provided in this embodiment of the invention can be divided into three stages: uploading IoT data, generating configuration commands, and issuing configuration commands.

[0038] First, IoT data is uploaded. In this embodiment of the invention, environmental data obtained through environmental sensors is converted into short message information to be sent. It should be noted that, in order to perform communication performance analysis, a header needs to be added to the short message to be sent, dynamically embedding monitoring identification information. Through a protocol encapsulation algorithm, this monitoring identification information is encapsulated in the header field of the initial short message information to generate the first short message.

[0039] Step 120: Send the first short message to the industry short message platform via satellite.

[0040] Specifically, the first short message not only carries the business data collected by the environmental sensors, but also the transmission sequence number and transmission timestamp added in the previous steps. The encapsulated first short message is sent to the BeiDou satellite via the BeiDou-3 short message module. After receiving the radio frequency signal, the BeiDou satellite forwards the information to the BeiDou short message ground system through its space relay link. The BeiDou short message ground system then forwards the short message information sent to the BeiDou satellite to the customer's industry short message platform.

[0041] Step 130: Receive a second short message from the industry short message platform, and parse the parameter configuration instructions based on the second short message.

[0042] Specifically, the BeiDou short message terminal receives a second short message from the industry short message platform transmitted via satellite. It should be noted that this second short message is generated by the industry short message platform based on the aforementioned link quality assessment results (such as packet loss rate and latency), and is forwarded to the satellite link via the BeiDou ground system.

[0043] The BeiDou short message terminal receives the second short message and parses out the parameter configuration instructions. The process of parsing the parameter configuration instructions preferably uses a preset dedicated communication protocol format for unpacking and parsing.

[0044] Step 140: Based on the parameter configuration instructions, adjust the transmission power and / or communication frequency of the Beidou short message terminal.

[0045] Specifically, after the BeiDou short message terminal parses the parameter configuration instructions, it needs to convert the parsing result into control primitives that the device configuration module can recognize, and set the terminal configuration according to the configuration parameters.

[0046] For example, if the current link packet loss rate is continuously higher than 15%, the Beidou short message terminal will increase the transmission power from the default 10W to 20W according to the instructions issued by the platform.

[0047] The remote configuration method for a BeiDou short message terminal provided in this invention adds monitoring identification information to the initial short message information, providing a basis for link quality analysis for the remote platform; by receiving short messages from industry short message platforms and parsing parameter configuration instructions, a remote closed-loop control link is established, enabling the terminal to dynamically obtain optimal configuration parameters based on the decision results of the backend algorithm; and by adjusting the transmission power and / or communication frequency of the BeiDou short message terminal based on the parameter configuration instructions, remote setting of the terminal's transmission power and communication frequency is achieved, thereby ensuring reliable communication transmission and the rational use of BeiDou communication channel resources.

[0048] In some embodiments, the monitoring identification information includes a transmission sequence number and a transmission timestamp; The sending sequence number is a unique sequence number generated by the Beidou short message terminal in a continuously incrementing manner each time a short message is sent.

[0049] Specifically, in this embodiment of the invention, the monitoring identification information includes a transmission sequence number and a transmission timestamp. Through the collaboration of these two, the industry short message platform can provide a comprehensive performance profile of the communication link from two dimensions: "completeness" and "real-time performance".

[0050] The transmission sequence number is a continuously incrementing value maintained by the processor inside the BeiDou short message terminal. Each time the terminal successfully constructs or sends the first short message frame, the value of the Serial Number Register (SN) in its internal memory is automatically incremented by 1. This sequence number is encapsulated along with the service data. Furthermore, to ensure uniqueness within a specific statistical period, this sequence number is typically represented by a sufficiently wide binary number (such as 16-bit or 32-bit).

[0051] The transmission timestamp records the absolute time scale from which the short message was initiated by the terminal. Considering the inherent time synchronization advantage of BeiDou terminals, the terminal prioritizes obtaining standard time synchronization information from the BeiDou satellite navigation system as its time source to ensure global synchronization between the terminal's time and the platform-side server time. In extreme cases where there is no satellite time synchronization signal, the terminal's internal high-precision real-time clock is invoked.

[0052] The remote configuration method for the BeiDou short message terminal provided in this embodiment of the invention provides data support for monitoring link quality of the industry short message platform by combining the sending sequence number and the sending timestamp. This facilitates real-time differentiation between "continuous packet loss caused by signal obstruction" and "high latency caused by channel congestion," providing quantitative triggering conditions for subsequent parameter adjustments.

[0053] In some embodiments, obtaining initial short message information, adding monitoring identification information to the initial short message information, and generating a first short message includes: Acquire information collected by environmental sensors and convert the information collected by the environmental sensors into initial short message information; The sending sequence number and the sending timestamp are added to the header of the initial short message information and encapsulated into the first short message.

[0054] Specifically, the terminal acquires information from environmental sensors through an IoT data acquisition module. Depending on the actual application scenario, environmental sensors may include, but are not limited to, temperature sensors, humidity sensors, pressure sensors, water level gauges, flow meters, or geolocation modules.

[0055] After acquiring the raw analog or digital signals from the sensor, the terminal performs format conversion, data compression, or byte alignment processing on the raw signals according to a preset industry communication protocol, thereby generating an initial short message. This initial short message constitutes the service data payload of this communication.

[0056] In order to enable the industry platform to perceive the quality status of the BeiDou satellite link in real time during subsequent processes, the terminal dynamically generates corresponding monitoring identifiers, namely the sending sequence number and the sending timestamp, while generating the initial short message information.

[0057] The generated monitoring identifier is physically merged with the service payload. Specifically, the terminal adds the sending sequence number and the sending timestamp at the beginning position of the initial short message information (i.e., in the message header) according to a preset byte offset, thereby encapsulating it into a first short message.

[0058] The remote configuration method for the BeiDou short message terminal provided in this embodiment of the invention achieves simultaneous transmission of business data and link status in the same message by performing "environmental information collection" and "communication quality probe injection" on the terminal side. This method does not change the original underlying communication protocol of BeiDou short messages, and utilizes the extremely limited message header byte space to provide the necessary original analysis dimension for subsequent remote parameter optimization based on link quality.

[0059] Figure 4 This is the second flowchart illustrating the remote configuration method for the BeiDou short message terminal provided by this invention, as shown below. Figure 4 As shown, the method includes steps 410, 420, 430, and 440. The executing entity of the remote configuration method for the BeiDou short message terminal provided by this invention can be an industry short message platform. Unless otherwise specified, subsequent embodiments will use an industry short message platform as an example for illustration.

[0060] Step 410: Receive short message information from the Beidou short message terminal and extract the monitoring identification information from the short message information.

[0061] Specifically, the industry short message platform, as the core of data processing, listens in real time and receives data uploaded by BeiDou short message terminals distributed in various locations through a two-way communication link established by the BeiDou short message ground system (such as a ground center station or service provider gateway). After the BeiDou satellite forwards the terminal message to the ground center station, the ground center station encapsulates the message into a standard data packet and forwards it to the platform.

[0062] like Figure 2As shown, the industry short message platform can achieve data interaction with the BeiDou short message ground system through the industry data interface module; perform business application-oriented information processing on the received short message system through the industry data processing module; realize the application display and analysis capabilities of industry data through the industry data application module; analyze performance data such as the success rate and market of received short messages through the communication performance analysis module; and generate configuration instructions for specific terminals through the configuration instruction sending module according to application requirements and the requirements for reasonable utilization of BeiDou channels.

[0063] The platform performs bit-level or byte-level decomposition of the received short message information according to the communication protocol agreed upon with the terminal in advance (which corresponds to the encapsulation logic on the terminal side in step 110).

[0064] The platform identifies the monitoring identifier area from a fixed offset position in the short message information (usually the message start segment), and extracts the monitoring identifier information, namely the sending sequence number and sending timestamp. After the monitoring identifier is extracted, the remaining message bytes are identified as the initial short message information, i.e., business data, and are transferred to the industry data processing module for routine business analysis.

[0065] It should be noted that while extracting the identification information, the platform will simultaneously record the local reception time of the message arriving at the platform.

[0066] Step 420: Based on the monitoring identification information, calculate the current link quality index between the Beidou short message terminal and the industry short message platform.

[0067] Specifically, the industry short message platform uses the monitoring identification information extracted from the first short message to quantitatively evaluate the real-time link status between the Beidou short message terminal and the industry short message platform through a preset statistical model.

[0068] In this embodiment of the invention, the current link quality indicators include data loss rate and data transmission duration. The platform assesses the stability of the uplink by performing continuity analysis on the "sending sequence number" of multiple received short messages and calculating the data loss rate. The platform assesses the transmission latency and congestion level of the link by comparing the "origin time" and "arrival time" of the messages and calculating the data transmission duration.

[0069] Step 430: Based on the current link quality indicators, determine the configuration parameters for the BeiDou short message terminal.

[0070] Specifically, the industry short message platform transforms abstract link statistics into concrete hardware control commands. Based on the analysis of communication performance data over a period of time, and combined with application needs and the communication optimization requirements of the BeiDou system, it calculates and determines the configuration parameters for the BeiDou short message terminal, namely the transmission power and communication frequency (Low Frequency 1 (LF1) / Low Frequency 2 (LF2)). Its core logic lies in dynamically finding the optimal balance between "communication success rate" and "terminal power consumption / spectrum resource usage" based on the current congestion level of the satellite channel or the obstruction situation of the terminal's environment.

[0071] Step 440: Encapsulate the configuration parameters into a second short message and send it to the BeiDou short message terminal via satellite.

[0072] Specifically, the industry short message platform will encode the parameter configuration values ​​determined by the aforementioned link analysis results according to the preset terminal control protocol, generate configuration parameter instructions, encapsulate the configuration parameter instructions into a second short message, forward it to the BeiDou satellite through the BeiDou short message ground system, and use the downlink (broadcast / communication link) of the BeiDou system to deliver the instructions across spatial dimensions to the remote device, thus completing closed-loop control.

[0073] Optionally, considering that the satellite link may still be unstable, the platform can also implement a reliable transmission strategy. For example, after the platform sends the command, it enters a waiting state. If it does not receive a "configuration success confirmation message" from the terminal within a preset time, it will automatically trigger a retransmission mechanism until confirmation is received or the maximum number of attempts is reached, thereby ensuring the determinism of remote configuration.

[0074] The remote configuration method for BeiDou short message terminals provided in this invention receives short message information, extracts monitoring identification information from it, and calculates the current link quality index based on the monitoring identification information, thereby achieving a precise quantitative evaluation of the communication performance of the BeiDou short message link. By determining targeted configuration parameters based on the link quality index, it achieves dynamic matching and intelligent decision-making between communication parameters and the actual channel environment. By encapsulating the configuration parameters into instructions and sending them to the terminal via satellite link, a complete remote closed-loop optimization mechanism is constructed. In environments without terrestrial network coverage, it enables remote configuration of the short message terminal, automatically optimizes terminal performance, and significantly improves communication reliability and channel utilization.

[0075] In some embodiments, the monitoring identification information includes a transmission sequence number and a transmission timestamp; The current link quality metrics include data loss rate and data transmission time. The step of calculating the current link quality index between the BeiDou short message terminal and the industry short message platform based on the monitoring identification information includes: The sending sequence number of multiple short messages received within a preset time period is counted, the sequence of missing sending sequence numbers is analyzed, and the data loss rate is calculated. The receiving time of the short message is obtained, and the time difference between the receiving time and the sending timestamp in the short message is calculated to obtain the data transmission duration.

[0076] Specifically, the monitoring identification information includes the transmission sequence number and transmission timestamp. Current link quality metrics include data loss rate and data transmission duration.

[0077] Data loss rate refers to the percentage of data packets that fail to reach the industry short message platform within a specific monitoring period or message sequence range due to reasons such as channel interference, physical obstruction, signal attenuation, or system congestion, out of the total number of data packets sent by the BeiDou short message terminal. In this embodiment of the invention, the data loss rate is a link quality indicator based on application layer sequence integrity. It is calculated by statistically analyzing the "sending sequence number" carried in the messages received by the industry short message platform within a preset observation window, identifying logical gaps between sequence numbers (i.e., missing sequence numbers), and comparing the number of missing sequence numbers with the expected total number of messages within that period.

[0078] Data transmission duration, also known as end-to-end transmission latency, refers to the total time span from the physical moment a single short message is initiated by the BeiDou short message terminal, through BeiDou satellite relay, ground station processing, and ground network transmission, to the moment it is successfully received by the industry short message platform. In this embodiment of the invention, data transmission duration is a link performance indicator calculated based on timestamp comparison. It is obtained by calculating the absolute difference between the "local system time" of the message received by the industry short message platform and the "sending timestamp" encapsulated in the message payload. This indicator covers terminal processing latency, space segment transmission latency, and ground segment relay latency, and is mainly used to reflect the current congestion level of the BeiDou short message channel and the system response efficiency.

[0079] The platform analyzes the sequence number in the message header and calculates the data loss rate based on the missing information. It statistically analyzes the sending sequence numbers of multiple short messages received within a preset time period, identifies any missing sequences, and calculates the data loss rate accordingly.

[0080] Within a preset time period (e.g., one hour or a cycle of receiving 50 consecutive messages), the platform extracts the transmission sequence number from each message and arranges them in a buffer sequence according to the order of reception. The continuity of the transmission sequence numbers is analyzed. If a discontinuous sequence number is detected (e.g., the received sequence is 001, 002, 004, 005), it is determined that there is a missing sequence (e.g., sequence number 003 is missing). This missing sequence corresponds to a packet loss event that occurred during the inbound link of the BeiDou short message service.

[0081] The platform calculates the data transmission duration by analyzing the sending timestamp in the message header and combining it with the receiving time. Upon receiving a short message, the platform records the current server system time, defined as the receiving time. The sending timestamp recorded by the terminal when initiating communication is parsed from the short message header, and the time difference between the receiving time and the sending timestamp is calculated to obtain the data transmission duration. The data transmission duration actually includes the sum of terminal internal processing latency, satellite uplink latency, satellite forwarding latency, ground station processing latency, and ground network transmission latency. By monitoring the trend of data transmission duration changes, such as a continuous increase, the platform can predict whether the BeiDou channel is entering a high-load or congested state.

[0082] The remote configuration method for the BeiDou short message terminal provided in this embodiment of the invention quantifies the link communication quality by calculating the data loss rate and data transmission duration, providing data support for configuring terminal parameters to ensure reliable communication transmission and the rational use of BeiDou communication channel resources.

[0083] In some embodiments, determining the configuration parameters for the BeiDou short message terminal based on the current link quality index includes: When the data loss rate exceeds a first preset range and / or the data transmission duration exceeds a second preset range, the configuration parameters for the BeiDou short message terminal are calculated. The configuration parameters include terminal transmit power and communication frequency parameters.

[0084] Specifically, in this embodiment of the invention, the configuration parameters include terminal transmit power and communication frequency parameters.

[0085] Terminal transmit power refers to the intensity of electromagnetic wave energy output from the radio frequency front-end of the BeiDou short message terminal and radiated into space via the antenna when performing the task of sending radio signals to satellites. It directly determines the link loss redundancy of the uplink signal after penetrating the atmosphere, vegetation, and building obstructions. In this embodiment of the invention, this power parameter is adjustable, and a dynamic balance between signal coverage and terminal power consumption can be achieved by changing the gain stage or bias voltage of the internal radio frequency power amplifier of the terminal.

[0086] Communication frequency parameters refer to the radio carrier center frequency or specific physical frequency band identifier selected when a BeiDou short message terminal interacts with a satellite. This parameter defines the physical location of the radio signal in the spectrum space. In the BeiDou short message system, this typically corresponds to different operating frequencies supported by the Radio Determination Satellite Service (RDSS) (inbound / outbound), such as the specific frequency bands LF1 and LF2 mentioned in this embodiment. This parameter determines the channel resource allocation for terminal access to the satellite system. By switching frequency parameters, it is possible to avoid co-channel interference, suppress multipath fading, and adaptively adjust to channel congestion.

[0087] Upon receiving a message with a monitoring identifier from a terminal, the industry short message platform does not necessarily change the terminal configuration immediately. Instead, it uses a preset threshold monitoring mechanism to determine whether the current communication quality has deteriorated to the point where optimization is needed. Only when link metrics deviate from the normal "preset range" will the platform initiate the recalculation of configuration parameters.

[0088] The platform continuously monitors link quality data received from specific terminals. Based on a preset first range, it determines whether the percentage of missing packets in N consecutive packets exceeds this range. If it does, it determines that the current link has physical obstruction or signal attenuation, triggering configuration calculations. The first preset range is determined based on application needs and the communication optimization requirements of the BeiDou system.

[0089] Based on a preset second preset range, it is determined whether the proportion of missing data in consecutive messages exceeds this second preset range. If the time difference T between the message being sent from the terminal and received by the platform, calculated using the sending timestamp, consistently exceeds the second preset range, it is determined that the current BeiDou channel is overloaded or there is severe network congestion, triggering configuration calculations. The second preset range is determined based on application needs and the communication optimization requirements of the BeiDou system.

[0090] The remote configuration method for the BeiDou short message terminal provided in this invention determines the configuration parameters based on the analysis of communication performance data over a period of time, combined with application needs and the communication optimization requirements of the BeiDou system. While effectively ensuring the high reliability of IoT monitoring data transmission in extreme environments, it significantly improves the allocation efficiency and utilization rate of BeiDou's limited short message channel resources, reduces unnecessary power consumption of the terminal, and ultimately realizes intelligent and refined closed-loop optimization of terminal communication performance in unattended scenarios.

[0091] The apparatus provided in the embodiments of the present invention will be described below. The apparatus described below can be referred to in correspondence with the method described above.
