[0057] The beneficial effects of the present application are:

[0058] The present application introduces a configurable cache period mechanism, realizes the dynamic capture and structured preprocessing of the transmission data of the Internet of Things communication base station, effectively optimizes the initial data processing efficiency; by strictly arranging the captured transmission data in ascending order of target frequency band value, an ordered transmission 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 spectrum requests. This ordered preprocessing based on frequency band value effectively reduces the computational overhead during subsequent frequency band correlation analysis and queue division, and provides a clear and low-redundancy input structure for efficient multi-frequency resource allocation and switching;

[0059] The present application constructs a coordinate axis by presetting the frequency band span to simplify the integration process of the frequency band resource; 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, and the transmission data is automatically classified into continuous scale intervals to form a transmission queue, realizing the physical adjacency aggregation of the frequency band resource; when determining the transmission frequency band interval, the highest and lowest target frequency band 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;

[0060] The present application takes the highest latency-sensitive transmission data in the transmission queue as a representative, binds it with the complete transmission frequency band interval where the data is located to generate a priority transmission feature, which avoids the calculation consumption of full-queue data sorting, and physically binds high-priority services and spectrum resources; secondly, by aggregating the priority features of all transmission queues and dynamically sorting them in descending order of latency sensitivity, an emergency service channel across frequency bands is constructed - high-priority features not only trigger their own transmission, but also directly lead to the synchronous release of 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 systems, while ensuring the overall utilization rate of associated frequency band resources, significantly improving the service reliability and real-time performance of the base station in high-concurrency Internet of Things scenarios;

[0061] The method is based on the bandwidth of the Internet of Things communication base station to construct a parallel transmission queue and an intelligent matching base station real-time load state transmission mechanism; when high priority features are sufficient (the number of features ≥ the number of parallel queues), immediately assign the highest emergency degree features to the parallel transmission queue, and trigger the overall transmission of the queue through the frequency band interval binding; when high priority features are insufficient, then fill in the next priority features, ensuring that the bandwidth is not idle; the mechanism focuses on the autonomous evolution capability of the transmission process-any queue completes high priority data transmission, and automatically fills the remaining data in the same frequency band queue in order, forming a "key business priority breakthrough + associated data continuous follow-up" transmission process; when the entire queue is empty, a new frequency band queue is activated from the global priority sequence and included in the parallel transmission queue for transmission; eliminate the decision delay and resource window period of traditional base station frequency band switching.

[0066] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0067] Example 1

[0068] The multi-frequency adaptive switching method based on the Internet of Things communication base station, as shown in Figure 1 , specifically includes the following:

[0069] The method focuses on the adaptive switching of the frequency band of the Internet of Things communication base station in the actual data transmission process, so as to improve the transmission efficiency of the data to be transmitted;

[0070] It should be noted that the method needs to meet the requirement that the Internet of Things communication base station has the ability to accurately extract the data to be transmitted and its target frequency band before being implemented;

[0071] Firstly, the data to be transmitted received by the Internet of Things communication base station needs to be determined. Based on the characteristics of the Internet of Things communication base station, the received data needs to be cached, so there is a certain hysteresis in the process of receiving-caching-transmitting. Therefore, real-time transmission (receiving and transmitting at the same time) is difficult to achieve in actual process. Based on this characteristic, a cache period is constructed. The length of the cache period needs to be determined by the operator in combination with the actual situation. Generally, it is related to the transmission performance of the Internet of Things communication base station (that is, the faster the processing speed of the same size of data to be transmitted in the process of receiving-caching-transmitting, the shorter the length of the cache period, and vice versa).

[0072] Any one Internet of Things communication base station is selected as the research object of the method (the following steps are also applicable to other Internet of Things communication base stations of the same type).

[0073] The current time is determined and recorded as the end time point of a cache period. Combined with the length of the cache period preset by the operator, the start time point of the cache period can be obtained.

[0074] Then, a plurality of data to be transmitted received by the Internet of Things communication base station from the start time point to the end time point of the cache period is determined, and the total number of the plurality of data to be transmitted is counted, denoted as .

[0075] Thus, the data to be transmitted in a cache period and the total number of the data to be transmitted are obtained. It should be noted that the current time is not a fixed condition as the end time point of a cache period. The current time can also be used as the start time point of a cache period, and a cache period in the future is determined in terms of length, and the end time point of the cache period is determined. In summary, the start time point and the end time point of a cache period can be determined according to actual needs.

[0076] Then, the target frequency bands associated with the determined data to be transmitted are extracted, and the target frequency bands are sorted (serialized) in ascending order according to the specific values of the target frequency bands. The sorted result is denoted as target frequency band sequence, represented as: .

[0077] The data to be transmitted is sorted in the order of the target frequency band sequence , and the data to be transmitted sequence is obtained, represented as: , wherein any one data to be transmitted corresponds to a target frequency band . For the index, the value range is 1 to ;

[0078] So far, the target frequency band sequence in this cache cycle is obtained and the to-be-transmitted data sequence ;

[0079] Then, the operator's preset frequency band span is obtained, and all target frequency bands associated with each 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 after clustering, a transmission queue sequence is obtained. The target frequency bands associated with all to-be-transmitted data in any one transmission queue in the transmission queue sequence are extracted to form a transmission frequency band interval associated with the transmission queue.

[0080] Then, the transmission deadlines of all to-be-transmitted data in the transmission queue are extracted from the determined any one 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);

[0081] The to-be-transmitted data with the highest time delay sensitivity is 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;

[0082] 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, a priority transmission feature is formed;

[0083] Similarly, the priority transmission features associated with all transmission queues in the transmission queue sequence are determined according to the above method, and all priority transmission features are sorted in descending order of the time delay sensitivity of the to-be-transmitted data. The sorted result is recorded as a priority transmission feature sequence;

[0084] Then, the number of maximum parallel transmission queues is determined based on the bandwidth of the Internet of Things communication base station (the transmission total number that can be accommodated at the same time, which is regarded as the determination of the transmission total number that can meet any data size of to-be-transmitted data, that is, the determination of the transmission total number is not affected by the size of the to-be-transmitted data), and a corresponding number of parallel transmission queues are constructed according to the number of maximum parallel transmission queues;

[0085] The priority transmission feature sequence determined in the current 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 is extracted and included in the parallel transmission queue for transmission operation.

[0086] 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 transmission queue (i.e., 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)

[0087] The frequency band interval of the parallel transmission queue is adjusted to the transmission frequency band interval associated with the transmission queue, and the transmission operation is performed.

[0088] If the to-be-transmitted data in the transmission queue associated with any transmission frequency band interval in the parallel transmission queue is transmitted, the priority transmission feature in the priority transmission feature sequence is continuously obtained and included in the parallel transmission queue, and the transmission queue associated with the newly included priority transmission feature is extracted and included in the parallel transmission queue. The frequency band interval of the parallel transmission queue is adjusted to the transmission frequency band interval of the newly included transmission queue, and the transmission operation is performed until all to-be-transmitted data in all transmission queues in the current cache period are transmitted.

[0089] The core of the 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 based on the setting of the operator is constructed, 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 preferentially. Finally, the maximum number of 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.

[0090] Embodiment 2

[0091] 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, as shown in Figure 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, as shown in

[0092] In embodiment 1, the frequency band span preset by the operator is denoted as , then, the data sequence to be transmitted is extracted again ;

[0093] The data sequence to be transmitted is determined The lowest data to be transmitted in the target frequency band in the data sequence to be transmitted, that is, the data to be transmitted , is extracted from the target frequency band sequence corresponding to the data sequence to be transmitted determined in Embodiment 1 ; The target frequency band corresponding to the data to be transmitted is extracted from the target frequency band sequence ; ;

[0094] The origin of the coordinate axis is taken as the target frequency band , and the scale of the coordinate axis is taken as the frequency band span , that is, the scale interval between the two scales of the constructed coordinate axis represents a frequency band span ;

[0095] It needs to be explained here that, in order to avoid disputes between age scales, the origin of the first scale interval is taken as 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;

[0096] 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 used 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 similar.

[0097] Then, all the data to be transmitted in the transmission data sequence is plotted on the constructed coordinate axis according to the position of the target frequency band in the target frequency band sequence corresponding to the transmission data sequence on the constructed coordinate axis;

[0098] At this time, the data to be transmitted distinguished by different scale intervals will be obtained, and the data to be transmitted in the same scale interval is taken as the same group, which is recorded as a transmission queue;

[0099] The total number of transmission queues plotted on the constructed coordinate axis is counted according to the above method, and is recorded as , and the obtained transmission queues are recorded in the order on the coordinate axis, which is recorded as a transmission queue sequence, and is represented as: , wherein, ;

[0100] At this point, the transmission queue sequence after clustering processing is obtained , any one of the determined transmission queue sequence is extracted, denoted as , and the transmission queue is processed by example, and the rest of the transmission queue sequence is processed in the same way as the transmission queue is processed, where n is a count index, and the value range is 1 to ;

[0101] All target frequency bands associated with the data to be transmitted are extracted from the determined transmission queue , 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 ;

[0102] At this point, the transmission frequency band interval associated with the transmission queue is obtained, and is denoted as: ;

[0103] By analogy, the above steps are repeated to obtain the transmission frequency band interval associated with each of the transmission queues in the transmission queue sequence , and the obtained transmission frequency band intervals are sorted in the order of the transmission queue sequence , denoted as: .

[0104] The embodiment clusters the transmission data sequence by constructing coordinate axes, aiming to realize reasonable grouping of data to be transmitted and accurate allocation of frequency band resources; specifically, the frequency band span is first set and the transmission data sequence is extracted, the lowest data of the target frequency band is found as the starting point, the coordinate axes with the target frequency band as the origin and the frequency band span as the scale are constructed, the definition rules of the scale intervals are clarified, the data to be transmitted is mapped to the coordinate axes according to the position of the target frequency band, forming multiple scale intervals, the data in each interval forms a transmission queue, and a transmission queue sequence is obtained; then, each transmission queue is further processed, the target frequency bands of all data to be transmitted in the transmission queue are extracted, the highest and lowest target frequency bands are determined, which 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 interval corresponding to each transmission queue is obtained and sorted in order; the purpose of this process is to effectively organize the data to be transmitted, so that the frequency band resources are reasonably divided and utilized.

[0105] Example 3

[0106] This embodiment, based on Embodiments 1 and 2, further discloses a method for constructing priority transmission features and determining parallel transmission queues, specifically including the following:

[0107] Extract the transmission queue determined in Example 2 Perform example processing;

[0108] Determine the transmission queue The deadline for transmitting all data to be transmitted;

[0109] Obtain the mapping relationship between the operator's preset transmission deadline and latency sensitivity (the shorter the transmission deadline, the higher the latency sensitivity; the longer the transmission deadline, the lower the latency sensitivity; the operator determines the mapping relationship between the transmission deadline and latency sensitivity based on this characteristic), and combine it with the transmission queue. The transmission deadline for all data to be transmitted determines the transmission queue. The latency sensitivity of all data to be transmitted.

[0110] Determine the transmission queue The data to be transmitted that has the highest latency sensitivity (i.e., the shortest transmission deadline) is denoted as . and the data to be transmitted The time delay sensitivity is denoted as: ;

[0111] Then determine the data to be transmitted The transmission queue The associated transmission frequency band interval is denoted as , will transmit data Delay sensitivity Transmission frequency band interval Combine them as a transmission queue The associated priority transmission characteristics.

[0112] Repeat the above steps to determine the transmission queue sequence. The priority transmission characteristics associated with each transmission queue in the sequence of transmission queues. There is There are several transmission queues, so the total number of priority transmission features obtained can be determined to be... One, represented as: (at this time (for disordered order)

[0113] Extract again middle The latency sensitivity associated with each priority transmission feature, and The priority transmission features are sorted in descending order of delay sensitivity, and the sorted result is denoted as the priority transmission feature sequence, as follows: .

[0114] The purpose of this embodiment is to improve the data transmission efficiency and resource allocation rationality of IoT communication base stations. By extracting the data to be transmitted and its transmission deadline from the transmission queue, the latency sensitivity of each data is determined using the mapping relationship preset by the operator. Then, the data with the highest latency sensitivity is identified, and a priority transmission feature containing the data, its latency sensitivity, and the transmission frequency band is constructed. This process is repeated to determine the priority transmission features of all transmission queues, and the priority transmission feature sequence is formed by sorting the features according to their latency sensitivity.

[0115] Example 4

[0116] This embodiment further discloses a method for determining a parallel transmission queue based on embodiment 1, specifically including the following:

[0117] Obtain the bandwidth of this IoT communication base station and record it as... (Bandwidth mentioned here) Therefore, the maximum bandwidth that an IoT communication base station can use during data transmission (i.e., the maximum bandwidth available for this purpose).

[0118] The operator then allocates appropriate bandwidth to any transmission queue. This bandwidth should satisfy the data transmission operations of any transmission queue, and the bandwidth preset by the operator is recorded as follows: ;

[0119] Extract the determined bandwidth and bandwidth ,use Determine the maximum total number of parallel transmission queues supported by this IoT communication base station. ,in This indicates rounding the calculation result down (i.e., );

[0120] Construct according to the total number of parallel transmission queues , build A parallel transmission queue.

[0121] This embodiment aims to combine the total bandwidth of the IoT communication base station with the transmission queue bandwidth preset by the operator to calculate the maximum number of parallel transmission queues supported by the base station, and to construct a corresponding number of parallel transmission queues accordingly.

[0122] Example 5

[0123] This embodiment, based on embodiments 1, 3, and 4, further discloses a method for performing transmission based on a parallel transmission queue, such as...Figure 3 As shown, it specifically includes the following:

[0124] The priority transmission feature sequence can be obtained through Examples 1, 3, and 4. and the total number of parallel transmission queues ;

[0125] Prioritize transmitting feature sequences The total number of priority transmission features Total number of parallel transmission queues The comparison will determine the strategy for transmission in two different directions;

[0126] First, if the total number is determined Greater than or equal to the total This indicates that the total number of parallel transmission queues is sufficient to handle the priority transmission of the characteristic sequence. All priority transmission features are transmitted simultaneously;

[0127] extract In a parallel transmission queue Parallel transmission queues (and) (the number of priority transmission features is the same), will The priority transmission features are sequentially incorporated In a parallel transmission queue;

[0128] It is important to note that at this time The frequency band intervals of the parallel transmission queues did not coincide with... Each priority transmission feature is associated with the same transmission frequency band, so it is necessary to... The frequency band interval of each parallel transmission queue is adjusted to match... Transmission can only be performed if the transmission frequency band intervals associated with the data to be transmitted in the priority transmission features are the same.

[0129] If during transmission In a parallel transmission queue Once the data to be transmitted in any one of the priority transmission features is completed, extract the transmission queue containing the data to be transmitted that has been transmitted.

[0130] The remaining untransmitted data in this transmission queue are sorted in descending order of latency sensitivity and then sequentially added to the parallel transmission queue where the data to be transmitted has been completed (the frequency band of this parallel transmission queue is the same as the transmission frequency band associated with the transmission queue where the data to be transmitted has been completed, so no adjustment is needed, and the target frequency band of all the data to be transmitted in this transmission queue can be satisfied).

[0131] Second, if the total number of the parallel transmission queues is less than the total number of the priority transmission features indicating that the total number of the parallel transmission queues cannot simultaneously transmit all the priority transmission features in the priority transmission feature sequence , then one priority transmission feature is extracted from the priority transmission feature sequence in the order of the sequence (the subsequent extracted priority transmission features are also extracted in the order of the sequence), and the extracted priority transmission feature is included in the parallel transmission queue ; The frequency band interval of the parallel transmission queue is also adjusted to be the same as the transmission frequency band interval associated with the to-be-transmitted data in the priority transmission feature, and transmission is performed. If the to-be-transmitted data in any one of the priority transmission features in the parallel transmission queue is completed during the transmission process, the transmission queue in which the to-be-transmitted data is located is extracted.

[0132] The remaining to-be-transmitted data in the transmission queue is sorted in the order of 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 frequency band interval of the parallel transmission queue is the same as the transmission frequency band interval associated with 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 the to-be-transmitted data in the transmission queue. If any one of the parallel transmission queues completes the transmission of all the to-be-transmitted data in a transmission queue, one untransmitted priority transmission feature is extracted from the priority transmission feature sequence in the order of the sequence, and the transmission operation on the priority transmission feature is continued until all the to-be-transmitted data in all the transmission queues in the transmission queue sequence

[0133] is completed, and the process is stopped (indicating that all the to-be-transmitted data in this cache period is completed, and the to-be-transmitted data in the next cache period is determined to perform the transmission operation).

[0136] ​​​​​​​The embodiment aims to perform data transmission of the Internet of Things communication base station. First, the number of priority transmission feature sequences 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 simultaneously. If not, the queue frequency band needs to be adjusted to match the transmission demand. If not, the priority order is gradually transmitted to ensure that critical data is processed first. At the same time, resources are dynamically managed during transmission. When a transmission task is completed, the remaining data is sorted by 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 transmission efficiency, and ensure the timeliness and integrity of data transmission.
