[0015] The beneficial effects of the present application are: The present application introduces a configurable cache period mechanism, which realizes dynamic capture and structured preprocessing of the data to be transmitted in the Internet of Things communication base station, effectively optimizing the initial data processing efficiency; by strictly arranging the captured data to be transmitted in ascending order of target frequency band value, an ordered data sequence is generated, which not only explicitly reveals the frequency band distribution characteristics of the data, but also converts discrete frequency band requests into continuous frequency spectrum requests. This ordered preprocessing based on frequency band value effectively reduces the computational overhead during subsequent frequency band correlation analysis and queue division, providing a clear and low-redundancy input structure for efficient multi-frequency resource allocation and switching. ​​​​The application greatly simplifies the integration process of frequency band resources by constructing coordinate axes for regular grouping through preset frequency band span; the first data frequency band is taken as the origin, and the frequency band span is taken as the scale to establish the partition standard, so that the to-be-transmitted data is automatically classified into continuous scale intervals to form a transmission queue, thereby realizing the physical adjacency aggregation of frequency band resources; when determining the transmission frequency band interval, the highest and lowest target frequency bands in the queue are directly taken as the interval boundaries, which not only retains the original frequency band distribution characteristics, but also avoids complex frequency band calculation and reduces real-time calculation overhead in the implementation process. The application avoids the calculation power consumption of full queue data sorting by taking the highest latency sensitivity of the to-be-transmitted data in the transmission queue as a representative to bind it with the complete transmission frequency band interval where the data is located to generate a priority transmission feature, and physically binds the high-priority service and the spectrum resource; secondly, the priority features of all transmission queues are aggregated and dynamically sorted in descending order of latency sensitivity to construct an emergency service channel across the frequency band-the high-priority feature not only triggers its own transmission, but also directly drags the synchronous release of the resources in the transmission queue of the bound frequency band interval; this "point-to-area" mechanism solves the problem that high-time-efficiency services are easily blocked by low-frequency queues in traditional multi-frequency band systems, while guaranteeing the overall utilization rate of associated frequency band resources, and significantly improves the service reliability and real-time performance of the base station in the high-concurrency Internet of Things scene; The method constructs parallel transmission queues and an intelligent matching base station real-time load state transmission mechanism based on the bandwidth of the Internet of Things communication base station; when the high-priority features are sufficient (the number of features is greater than the number of parallel queues), the highest emergency degree feature is immediately allocated to the parallel transmission queue, and the transmission of the whole queue is triggered through frequency band interval binding; when the high-priority features are insufficient, the next priority features are supplemented downward to ensure that the bandwidth is not idle; the mechanism focuses on the autonomous evolution capability of the transmission process-any queue completes the transmission of high-priority data, and then automatically fills the remaining data in the same frequency band queue in sequence to form a transmission process of "key service priority breakthrough + associated data continuous follow-up"; when the whole queue is empty, a new frequency band queue is activated from the global priority sequence to be included in the parallel transmission queue for transmission; the decision delay and resource empty window period of the traditional base station frequency band switching are eliminated.

[0017] Figure 1 is a flowchart of the method described in the application; Figure 2 is a flowchart of the method described in Example 2 of the application; Figure 3 is a flowchart of the method described in Example 3 of the application. DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] Example 1 Multi-band adaptive switching method based on IoT communication base station, such as Figure 1 As shown, specifically including the following: This method focuses on adaptively switching the frequency band of IoT communication base stations during actual data transmission to improve the transmission efficiency of the data to be transmitted. It should be noted that before this method is implemented, it is necessary for the IoT communication base station to have the ability to accurately extract the data to be transmitted and its target frequency band; First, it is necessary to clearly define the data to be transmitted received by the IoT communication base station. This method is based on the characteristics of the IoT communication base station: after receiving the data, it needs to be cached. Therefore, there is a certain delay in the process of receiving, caching, and transmitting. Therefore, real-time transmission (receiving and transmitting simultaneously) is difficult to achieve in practice. Based on this characteristic, a cache period is constructed. The duration of the cache period needs to be determined on-site by the operator based on the actual situation. Generally, it is related to the transmission performance of the IoT communication base station (that is, for data of the same size to be transmitted, the faster the processing speed in the process of receiving, caching, and transmitting, the shorter the cache period, and vice versa). Select any IoT communication base station as the research object of this method (the following steps are also applicable to other IoT communication base stations of the same type); Determine and record the current time as the end time of a cache cycle. Combined with the cache cycle duration preset by the operator, the start time of this cache cycle can be obtained. Then determine the number of data to be transmitted received by the IoT communication base station during the time interval from the start time point to the end time point of the cache cycle, and count the total number of data to be transmitted, which is recorded as ; At this point, the data to be transmitted and the total number of data to be transmitted within a cache cycle are obtained. It should be noted that using the current moment as the end time point of a cache cycle is not a fixed condition. The current moment can also be used as the start time point of a cache cycle, and the length of a cache cycle can be determined in the future to determine the end time point of this cache cycle. In summary, the start time point and end time point of a cache cycle can be determined according to actual needs.

[0020] Next, the target frequency bands associated with each of the determined to-be-transmitted data are extracted, and the target frequency bands are sorted (sequence processing) in ascending order according to the specific values of the target frequency bands, and the sorted result is recorded as a target frequency band sequence, denoted as: ; The to-be-transmitted data are sorted in the sorting order of the target frequency band sequence , and a to-be-transmitted data sequence is obtained, denoted as: , wherein the target frequency band associated with each of the to-be-transmitted data , is a count index, and the value range is 1 to ; Up to now, the target frequency band sequence and the to-be-transmitted data sequence in the current cache period are obtained; Next, the frequency band span preset by the operator is obtained, and the target frequency bands associated with all to-be-transmitted data in the to-be-transmitted data sequence are clustered by combining the frequency band span, that is, all to-be-transmitted data in the to-be-transmitted data sequence are clustered, and a transmission queue sequence is obtained after clustering. The target frequency bands associated with all to-be-transmitted data in any transmission queue in the transmission queue sequence are extracted to form a transmission frequency band interval associated with the transmission queue.

[0021] Next, the transmission deadlines of all to-be-transmitted data in any transmission queue and the transmission frequency band interval associated with the transmission queue are extracted from the determined any transmission queue and the transmission frequency band interval associated with the transmission queue, and the time delay sensitivity of each to-be-transmitted data is determined (the shorter the transmission deadline, the higher the time delay sensitivity, and vice versa, the lower the time delay sensitivity); The to-be-transmitted data with the highest time delay sensitivity are extracted from the determined transmission queue, and the time delay sensitivity of the to-be-transmitted data is extracted. The transmission frequency band interval in which the to-be-transmitted data and the transmission queue are located is extracted; together with the to-be-transmitted data, the time delay sensitivity of the to-be-transmitted data, and the transmission frequency band interval associated with the to-be-transmitted data to form a priority transmission feature; Similarly, the priority transmission features associated with each of the transmission queues in the transmission queue sequence are determined according to the above method, and all the priority transmission features are sorted in descending order according to the time delay sensitivity of the to-be-transmitted data in the priority transmission features. The sorted result is recorded as a priority transmission feature sequence; ​​Determine the number of maximum parallel transmission queues based on the bandwidth of the Internet of Things communication base station (the total number of transmission that can be accommodated at the same time, here the determination of the total number of transmission is considered to meet any data size of the to-be-transmitted data, that is, the determination of the total number of transmission is not affected by the size of the to-be-transmitted data), and construct a corresponding number of parallel transmission queues according to the number of maximum parallel transmission queues; Then, the priority transmission feature sequence determined in this cache period is sequentially included in the parallel transmission queue for transmission operation, in addition, the to-be-transmitted data in the transmission frequency band interval associated with the transmission queue of the priority transmission feature sequence needs to be extracted and included in the parallel transmission queue for transmission operation; In the transmission process, the frequency band of the parallel transmission queue needs to be adjusted to the transmission frequency band interval associated with the corresponding transmission queue (that is, the target frequency band of each to-be-transmitted data in the transmission queue is located in the frequency band of the parallel transmission queue) Adjust the frequency band interval of the parallel transmission queue to the transmission frequency band interval associated with the corresponding transmission queue, and perform transmission operation; If the to-be-transmitted data in the transmission queue associated with any transmission frequency band interval in the parallel transmission queue is transmitted, continue to obtain the priority transmission feature in the priority transmission feature sequence and include it in the parallel transmission queue, extract the transmission queue associated with the newly included priority transmission feature and include it in the parallel transmission queue, adjust the frequency band interval of the parallel transmission queue to the transmission frequency band interval of the newly included transmission queue, and perform transmission operation, until all to-be-transmitted data in all transmission queues in the current cache period are transmitted.

[0022] The core of this embodiment is to realize efficient data management and frequency band switching scheduling; first, the receiving, caching, and transmission characteristics of the Internet of Things communication base station are determined, a cache period is constructed based on the setting of the operator, and the to-be-transmitted data and the total number in the cache period are determined; then, the target frequency band of the to-be-transmitted data is extracted and sorted to form a target frequency band sequence and a to-be-transmitted data sequence; then, the data is clustered according to the preset frequency band span to determine the transmission queue sequence and the associated transmission frequency band interval; then, the time delay sensitivity of the to-be-transmitted data in the transmission queue is extracted to determine the data with the highest time delay sensitivity, and a priority transmission feature sequence is constructed to ensure that data with high time delay requirements can be transmitted first; finally, the number of maximum parallel transmission queues is determined based on the bandwidth of the Internet of Things communication base station and the corresponding queues are constructed, the priority transmission feature sequence is sequentially included for transmission, and the frequency band of the parallel transmission queue is adjusted to match the associated frequency band interval of the transmission queue; in the whole process, the parallel transmission queue also needs to be dynamically updated according to the transmission completion condition.

[0023] Embodiment 2 The embodiment discloses a method for determining a transmission queue sequence and a transmission frequency band interval associated with all transmission queues in the transmission queue sequence, and the method comprises the following steps: Figure 2 as shown in the following table, and specifically comprises the following steps: In the embodiment 1, the frequency band span preset by the operator is denoted as , and then the to-be-transmitted data sequence is extracted. The lowest to-be-transmitted data in the target frequency band in the to-be-transmitted data sequence is determined, that is, the to-be-transmitted data , and the target frequency band corresponding to the to-be-transmitted data is extracted from the target frequency band sequence corresponding to the to-be-transmitted data sequence determined in the embodiment 1. ; The target frequency band is taken as the origin of the coordinate axis, and the frequency band span is taken as the scale of the coordinate axis to construct the coordinate axis, that is, the scale interval between two scales on the constructed coordinate axis represents a frequency band span . It should be explained here that, in order to avoid disputes between age scales, the origin of the method is the starting scale of the first scale interval; the starting scale of any scale interval is contained in the scale interval, and the ending scale is not contained in the scale interval. For example, the origin is the first scale, a scale interval is formed between the first scale and the second scale, the first scale is the starting scale of the scale interval and the second scale is the ending scale of the scale interval, the first scale is contained in the scale interval, the second scale is not contained in the scale interval, and the second scale will be taken as the starting scale of the scale interval formed by the second scale and the third scale, that is, the second scale is contained in the scale interval formed by the second scale and the third scale, and the subsequent scales are the same.

[0024] Then, all the to-be-transmitted data in the transmission data sequence are plotted on the constructed coordinate axis according to the positions of the target frequency bands in the target frequency band sequence corresponding to the transmission data sequence on the constructed coordinate axis. At this time, the to-be-transmitted data distinguished by different scale intervals will be obtained, the to-be-transmitted data in the same scale interval is taken as the same group, and is denoted as a transmission queue. The total number of the transmission queues plotted on the constructed coordinate axis is counted according to the above method, and is denoted as , and the obtained is obtained. ​The transmission queue sequence is denoted as , wherein ; At this point, the transmission queue sequence after clustering is obtained , any one of the determined transmission queue sequence is extracted, denoted as , and example processing is performed on the transmission queue , and the remaining transmission queues in the transmission queue sequence are processed in the same way as the transmission queue , wherein n is a count index, and the value range is 1 to ; All target frequency bands associated with the to-be-transmitted data in the determined transmission queue are extracted, and the highest target frequency band and the lowest target frequency band are further determined, and the highest target frequency band is taken as the maximum value in the transmission frequency band interval associated with the transmission queue ; similarly, the lowest target frequency band is taken as the minimum value in the transmission frequency band interval associated with the transmission queue ; At this point, the transmission frequency band interval associated with the transmission queue is obtained, and is denoted as ; By repeating the above steps, the transmission frequency band intervals associated with all transmission queues in the transmission queue sequence are obtained, and the obtained transmission frequency band intervals are sorted in the order of the transmission queue sequence , denoted as .

[0025] The embodiment clusters the transmission data sequence by constructing the coordinate axis, aiming to realize reasonable grouping of the to-be-transmitted data and accurate allocation of the frequency band resources; specifically, the frequency band span is set and the to-be-transmitted data sequence is extracted, the lowest data of the target frequency band is found as the starting point, the coordinate axis with the target frequency band as the origin and the frequency band span as the scale is constructed, the definition rule of the scale interval is determined, the to-be-transmitted data is mapped to the coordinate axis according to the position of the target frequency band, a plurality of scale intervals are formed, the data in each interval forms a transmission queue, and the transmission queue sequence is obtained; then, each transmission queue is further processed, the target frequency bands of all to-be-transmitted data in the transmission queue are extracted, the highest and lowest target frequency bands are determined, and the highest and lowest target frequency bands are taken as the maximum value and the minimum value of the transmission frequency band interval associated with the transmission queue, and finally the transmission frequency band intervals corresponding to the transmission queues are obtained and sorted in order; the purpose of this process is to effectively organize the to-be-transmitted data and reasonably divide and utilize the frequency band resources.

[0026] Example 3 This embodiment further discloses a method for constructing a priority transmission feature and determining a parallel transmission queue based on Embodiment 1 and Embodiment 2, specifically including the following: Extract the transmission queue determined based on Example 2 Perform sample processing; Determine the transmission queue The transmission deadline of all data to be transmitted; Obtain the mapping relationship between the transmission deadline and delay sensitivity preset by the operator (the shorter the transmission deadline, the higher the delay sensitivity; the longer the transmission deadline, the lower the delay sensitivity. The operator determines the mapping relationship between the transmission deadline and delay sensitivity based on this feature), and combine it with the transmission queue The transmission deadline of all data to be transmitted in the transmission queue is determined The delay sensitivity of all data to be transmitted in .

[0027] Determine the transmission queue The data to be transmitted with the highest delay sensitivity (i.e., the shortest transmission deadline) is denoted as , and the data to be transmitted The delay sensitivity of is denoted as: ; Then confirm the data to be transmitted The transmission queue The associated transmission frequency band interval is recorded as , the data to be transmitted , delay sensitivity , transmission frequency band Combined as a transmission queue The associated priority transmission characteristics.

[0028] Repeat the above steps to determine the transmission queue sequence The priority transmission characteristics associated with each of the transmission queues in the There are transmission queues, so the resulting priority transmission characteristics can be determined to be , expressed as: (at this time is out of order); Re-extraction middle The delay sensitivity associated with each priority transmission feature, and The priority transmission features are sorted in descending order of delay sensitivity, and the sorted results are recorded as the priority transmission feature sequence, which is expressed as: .

[0029] The embodiment aims to improve the data transmission efficiency and resource allocation rationality of the Internet of Things communication base station; by extracting the to-be-transmitted data and its transmission deadline time in the transmission queue, using the mapping relationship preset by the operator to determine the time delay sensitivity of each data, and then finding out the data with the highest time delay sensitivity, constructing the priority transmission characteristics including the data, its time delay sensitivity and transmission frequency band interval; repeating the process to determine the priority transmission characteristics of all transmission queues, and sorting the characteristics according to the time delay sensitivity to form a priority transmission characteristic sequence.

[0030] Embodiment 4 The embodiment continues to disclose a method for determining parallel transmission queues based on the embodiment 1, which specifically includes the following: Obtain the bandwidth of the Internet of Things communication base station, and mark it as (The bandwidth described herein refers to the maximum bandwidth that can be used by the Internet of Things communication base station in the process of transmitting data); For the maximum bandwidth that can be used by the Internet of Things communication base station in the process of transmitting data); Then, the operator assigns a corresponding bandwidth to any one transmission queue, which should meet the data transmission operation of any one transmission queue, and marks the bandwidth preset by the operator as ; Extract the determined bandwidth and the bandwidth , and use to determine the total number of maximum parallel transmission queues supported by the Internet of Things communication base station , wherein represents the downward rounding of the calculation result (i.e. ); According to the total number of parallel transmission queues , construct parallel transmission queues.

[0031] The embodiment aims to combine the total bandwidth of the Internet of Things communication base station and the transmission queue bandwidth preset by the operator, calculate the total number of maximum parallel transmission queues supported by the base station, and construct a corresponding number of parallel transmission queues accordingly.

[0032] Embodiment 5 The embodiment continues to disclose a method for performing transmission based on parallel transmission queues based on the embodiments 1, 3 and 4, as shown in Figure 3 , which specifically includes the following: The priority transmission characteristic sequence and the total number of parallel transmission queues can be obtained by the embodiments 1, 3 and 4; The total number of priority transmission characteristics in the priority transmission characteristic sequence is Total number of parallel transmission queues The comparison results will determine the execution transmission strategies in two different directions; First, if the total number is determined Greater than or equal to the total , it means that the total number of parallel transmission queues can afford the priority transmission feature sequence All priority transmission features are transmitted simultaneously; extract Parallel transmit queues parallel transmit queues (with The same number of priority transmission features) The priority transmission features are included in turn parallel transmission queues; It should be noted that at this time The frequency band intervals of the parallel transmission queues are not consistent with The transmission frequency band intervals associated with each priority transmission feature are the same, so it is necessary to The frequency band of the parallel transmission queues is adjusted to The transmission can be performed only after the transmission frequency band intervals associated with the data to be transmitted in the priority transmission characteristics are the same; If during the transmission Parallel transmit queues When the data to be transmitted in any one of the priority transmission features is completed, the transmission queue where the data to be transmitted is located is extracted; The remaining untransmitted data to be transmitted in this transmission queue are sorted in descending order of delay sensitivity, and are sequentially included in the parallel transmission queue where the data to be transmitted has completed transmission (the frequency band interval of this parallel transmission queue is the same as the transmission frequency band interval associated with the transmission queue where the data to be transmitted has completed transmission, so no adjustment is required, and the target frequency band of all data to be transmitted in this transmission queue can be met).

[0033] Second, if the total number is determined Less than the total (Indicates that the total number of parallel transmission queues cannot afford the priority transmission feature sequence All priority transmission features in the sequence are transmitted simultaneously), then from the priority transmission feature sequence Extract in sorted order Priority transmission features (subsequent extraction of priority transmission features is also extracted in the sorting order), and the extracted Priority transmission features are included parallel transmission queues; Same adjustment the transmission frequency band interval of the transmission queue in which the to-be-transmitted data is located is the same as the transmission frequency band interval of the transmission queue of the parallel transmission queue in which the to-be-transmitted data is located, and the transmission is performed; the transmission frequency band interval of the transmission queue in which the to-be-transmitted data is located is the same as the transmission frequency band interval of the transmission queue of the parallel transmission queue in which the to-be-transmitted data is located, and the transmission is performed; if the to-be-transmitted data in any one of the parallel transmission queues is completed during the transmission process, if the to-be-transmitted data in any one of the parallel transmission queues is completed during the transmission process, if the to-be-transmitted data in any one of the parallel transmission queues is completed during the transmission process, the remaining to-be-transmitted data in the transmission queue is sorted according to the time delay sensitivity from high to low, and is sequentially included in the parallel transmission queue in which the to-be-transmitted data is completed (the transmission frequency band interval of the parallel transmission queue is the same as the transmission frequency band interval of the transmission queue in which the to-be-transmitted data is located, so it does not need to be adjusted, and can meet the target frequency band of all to-be-transmitted data in the transmission queue).

[0034] if any one of the parallel transmission queues completes the transmission of all to-be-transmitted data in a transmission queue, if any one of the parallel transmission queues completes the transmission of all to-be-transmitted data in a transmission queue, a to-be-transmitted priority transmission feature is sequentially extracted from the priority transmission feature sequence, and the transmission operation is continued to be performed on the priority transmission feature until all to-be-transmitted data in all transmission queues in the transmission queue sequence is completed, and the transmission is stopped (which indicates that all to-be-transmitted data in the current cache period is completed, and the to-be-transmitted data in the next cache period is determined to perform the transmission operation).

[0035] The purpose of the embodiment is to perform data transmission of an Internet of Things communication base station. First, the number of priority transmission features is compared with the total number of parallel transmission queues to determine the transmission strategy. When the number of parallel transmission queues is sufficient, all priority features can be transmitted at the same time, and the queue frequency band needs to be adjusted to match the transmission demand. If it is insufficient, the data is transmitted in priority order to ensure that critical data is processed first. At the same time, resources are dynamically managed during the transmission process. When a transmission task is completed, the remaining data is sorted according to the priority and supplemented into the idle queue to avoid resource waste. The final goal is to fully utilize the transmission capacity of the base station, improve the transmission efficiency, and ensure the timeliness and integrity of data transmission.
