Taking a certain 4g+5g dual-mode base station as an example, the base station can start and process 4G cells and 8 5G cells in parallel, and compared with serial processing time delay, parallel processing time delay is greatly reduced, but because base station resources (such as DDR bus rate, shared Memory size, number of hardware accelerators, etc.) are limited, if parallel processing exceeds a certain number of cells, and when time slots are continuously scheduled, the data reading and writing data volume is too large at the same time, and the data volume to be processed exceeds the upper limit of the processing capacity of the base station, at the moment, the physical layer function module of the base station is blocked, thereby greatly reducing the operation efficiency of the base station.
Based on the above, the embodiment of the application provides a base station resource scheduling optimization method, which is beneficial to avoiding further deterioration of the blocking condition of a physical layer functional module on one hand and improving the operation efficiency of a base station when the physical layer functional module is blocked; on the other hand, the method is beneficial to reasonably utilizing limited base station resources to realize the corresponding functions of the functional modules, and is beneficial to further improving the operation efficiency of the base station.
The base station resource scheduling optimization method can be used for single-mode base stations or dual-mode base stations for performing multi-cell parallel starting and processing.
The method for optimizing the base station resource scheduling is described in detail below. Referring to fig. 1, an embodiment of the present application provides a method for optimizing base station resource scheduling, which includes:
step S110: acquiring a task to be processed from a task processing queue;

Step S130 allocates base station resources for the physical layer function module, including: and preferentially distributing the base station resources for the physical layer functional modules with high resource scheduling priority.
It will be appreciated that the task processing queue in step S110 is a data structure for storing tasks to be processed, and the tasks are arranged according to a first-in first-out principle, i.e. the task that is first to enter the queue will be processed first. The task processing queues may be implemented using a variety of data structures, such as linked lists, arrays, and the like. In a base station for performing multi-cell parallel starting and processing, one or more task processing queues are set for each cell, and at the same time, a plurality of task processing queues corresponding to a plurality of cells can work simultaneously, so that multi-cell parallel starting and processing is realized.
It can be understood that the physical layer function modules in the above step S120 refer to a series of function modules that form a physical layer structure of the base station, and mainly include:
The signal transmission module is mainly responsible for the functions of signal channel equalization, modulation and demodulation, channel coding and decoding and the like;

and the radio frequency processing module is used for generating and receiving radio frequency signals and carrying out filtering, amplifying and other processing on the radio frequency signals.
It will be appreciated that the above described functional modules are only some examples of physical layer functional modules of a base station and are not specific limitations of the physical layer functional modules. In addition, each physical layer function module has specific functions and roles, and the basic functions of the base station are completed in a cooperative mode.
It will be understood that the blocking in step S130 refers to that the functional module is blocked or delayed in implementing its function, so that the function that it should implement cannot be implemented in time.
It may be understood that the above base station resources refer to base station hardware resources, which are the basis for supporting normal operation of the physical layer functional module, and the base station resources may include:
(1) Computing resources: refers to hardware resources for processing data and executing instructions, such as high performance processors, graphics processor GPUs, hardware accelerators, etc.;
(2) Storage resources: refers to hardware resources, such as caches, flash memory, hard disks, etc., for storing data and programs;
(3) Communication resources: refers to hardware resources, such as communication interfaces, communication buses, etc., for data transmission and network communications.
The following describes tasks processed by the base station, physical layer function modules related to the tasks, and relationships between base station resources:
The task is the specific operation to be completed by the base station, the physical layer functional module is the specific component for realizing the related operation, and the base station resource is the basic hardware resource for supporting the normal operation of the functional module.
It may be understood that, the above-mentioned resource scheduling priority may be a priority allocated to the blocked physical layer function module after determining that the physical layer function module is blocked, and the following description will be given of a configuration scheme of the resource scheduling priority:
As an optional implementation manner of the above base station resource scheduling optimization method, before allocating base station resources to the physical layer function module according to the resource scheduling priority in step S130, the above base station resource scheduling optimization method further includes: determining whether a physical layer function module is blocked; and configuring the resource scheduling priority of the base station resources in the base station chip for the physical layer function module with the blocking according to a preset priority configuration rule.
It can be appreciated that the above method for determining whether the physical layer function module is blocked may be: and acquiring a multi-cell parallel processing flow time sequence diagram according to the subframe structures of the 4G and the 5G, the data arrival time, the starting time sequence of each functional module, the processing time of each module and the like, so as to judge which functional modules are blocked according to the processing flow time sequence diagram, for example, if the processing time consumption of a certain functional module is obviously abnormal, judging that the module is blocked.
It can be understood that the preset priority configuration rule may be a priority configuration rule preset according to a resource scheduling priority and a blocking degree of the functional module, and a specific setting scheme will be described in detail below.
In addition, it is understood that the step S130 further includes: and when the physical layer functional module is not blocked, directly distributing base station resources for the physical layer functional module so as to enable the physical layer functional module to realize corresponding functions.
According to the scheme, the resource scheduling priority of the base station resources in the base station chip can be configured for the physical layer functional module with the blocking according to the preset priority configuration rule, so that the functional module with the blocking can reasonably allocate the base station resources according to the resource scheduling priority, and the base station operation efficiency is improved.
The following describes in detail a method for judging whether the physical layer functional module is blocked or not:
The base station resource scheduling optimization method in the embodiment of the application can judge whether the functional module is blocked or not from the perspective of the base station resource alone, from the perspective of the functional module alone and from the perspective of combining the base station resource and the functional module, and the three embodiments are respectively described in detail below:
First embodiment: solely from the base station resource perspective;
as an optional implementation manner of the base station resource scheduling optimization method, the determining whether the physical layer function module is blocked includes: counting the total resource amount of base station resources in the base station used by a physical layer function module of each cell belonging to the same base station at the current moment; and determining whether the physical layer functional module is blocked or not and determining the blocking degree according to the total resource amount and a preset total resource amount threshold value.
The total amount of resources may be the total number of resources or the total size of resources, and an example is explained below how to determine whether the physical layer function module is blocked and the blocking degree according to the total amount of resources and a preset total amount of resources threshold value:
Taking a functional module of digital communication signal equalization processing as an example, the module needs to call FDEQ hardware accelerators when realizing the function of the functional module, in the process of parallel processing of a base station to a plurality of cells, the situation that a plurality of digital communication signal equalization processing modules call FDEQ hardware accelerators together at a certain moment may exist, and because the number of FDEQ hardware accelerators is limited, some digital communication signal equalization processing modules do not call FDEQ hardware accelerators so as to cause blocking.
At this time, the total amount of resources of the base station resource, i.e. the FDEQ hardware accelerator, can be counted by the digital communication signal equalization processing module at the moment, then the digital communication signal equalization processing module is judged to be blocked according to the preset total amount of resources threshold value set by the number of the FDEQ hardware accelerators, and among the modules with the blocking, the higher the demand of the FDEQ hardware accelerator is, the higher the blocking degree is.
It can be appreciated that the method for obtaining the number of FDEQ hardware accelerators described above may be: the number of hardware accelerators is determined FDEQ based on the number of FDEQ hardware accelerators returned after successful initialization FDEQ of the hardware accelerators.
Of course, it is understood that, in addition to the number FDEQ of hardware accelerators, the preset total resource amount threshold of the FDEQ hardware accelerator may be set by the maximum support number of FDEQ hardware accelerators, and the maximum support number of FDEQ hardware accelerators may be queried from the chip manual.
In addition, the preset total resource amount threshold of FDEQ hardware accelerators may be set according to the maximum value of FDEQ hardware accelerator number and FDEQ hardware accelerator maximum support number.
It will be appreciated that a functional module that blocks may be understood as a functional module that cannot meet the operation requirement of the base station resource, and taking the above example as an example, in this example, some digital communication signal equalization processing modules that can meet the operation requirement of the FDEQ hardware accelerator are not blocked, while other digital communication signal equalization processing modules that cannot meet the operation requirement are blocked.
According to the scheme, the total resource amount of the base station resources in the base station used by the physical layer function modules of each cell belonging to the same base station is counted, whether the physical layer function modules are blocked or not and the blocking degree of the blocking can be determined by combining the preset total resource amount threshold, and the blocking function modules are determined from the aspect that whether the base station resources can meet the requirements of the function modules or not, so that the method is beneficial to rapidly and efficiently distributing resource scheduling priorities to the blocking function modules, and further is beneficial to improving the operation efficiency of the base station.
Second embodiment: from the functional module perspective alone;
as an optional implementation manner of the base station resource scheduling optimization method, the determining whether the physical layer function module is blocked includes: counting the processing time consumption of each physical layer functional module at the current moment; and determining whether the physical layer functional module is blocked and the blocking degree according to the processing time consumption and the time consumption threshold.
It can be understood that the processing time consumption of each physical layer function module can be obtained by recording the processing start time and the processing end time of each physical layer function module by using a clock function and then obtaining the processing time consumption of the physical layer function module according to the difference between the processing end time and the processing start time.
The time consumption threshold may be determined by: and determining according to the processing time consumption of the corresponding physical layer functional module when the single cell is processed.
In addition, it will be appreciated that the performance decay factor may be set when the time consumption threshold is set, i.e. to allow the processing time of the physical layer function module to be slightly greater when the base station performs multi-cell parallel start-up and processing than when the base station performs single-cell start-up and processing. The performance attenuation factor can be 1.1-1.3, and the specific value can be adjusted according to the reporting delay requirement of the functional module.
It will be appreciated that if the processing time of the physical layer function module is greater than the time consumption threshold, it may be determined that the physical layer function module is blocked, and the blocking degree of the physical layer function module may be determined by a difference between the processing time of the physical layer function module and the time consumption threshold, for example: the blocking degree of the physical layer functional module is determined by the ratio of the difference value between the processing time consumption and the time consumption threshold value of the physical layer functional module and the time consumption threshold value, namely the processing time delay ratio.
According to the scheme, whether the physical layer functional module is blocked or not and the blocking degree are determined through more visual processing time of the functional module, so that resource scheduling priority can be distributed to the blocked functional module in a quick and efficient manner, and further the operation efficiency of the base station can be improved.
In a third embodiment, the base station resource and the functional module are combined to judge whether the physical layer functional module is blocked or not and the blocking degree of the blocking;
As an optional implementation manner of the base station resource scheduling optimization method, the determining whether the physical layer function module is blocked includes: counting the total resource amount of the base station resources in the base station used by the physical layer function module of each cell belonging to the same base station at the current moment, and consuming time for processing of each physical layer function module; and determining whether the physical layer functional module is blocked and the blocking degree according to the total resource amount, the preset total resource amount threshold value, the processing time consumption and the time consumption threshold value.
The solution for judging whether the blocking occurs according to the total amount of resources and the preset total amount of resources and the solution for judging whether the blocking occurs according to the time-consuming processing and time-consuming processing thresholds are referred to in the detailed description of the first embodiment and the second embodiment of the foregoing, and the embodiments of the present application are not repeated.
It may be understood that, if the congestion determination result obtained according to the total amount of resources and the preset total amount of resources is referred to as a first determination result and the congestion determination result obtained according to the time-consuming processing and time-consuming threshold is referred to as a second determination result, the above scheme for determining whether the physical layer function module is congested and the congestion degree according to the total amount of resources, the preset total amount of resources, the time-consuming processing and time-consuming threshold together may be as follows:
Case one: both judging results are that blocking occurs;
If the first judging result and the second judging result are both blocking, finally judging that the physical layer functional module is blocked;
and a second case: one of the two judging results is that the blockage occurs, and the other judging result is that the blockage does not occur;
If one of the first determination result and the second determination result is that the blocking occurs, and the other determination result is that the blocking does not occur, it may be determined that the physical layer function module is blocked, or it may be determined that the physical layer function module is not blocked.
Of course, in this case, the final determination result may also be obtained by the confidence degrees set in advance for the two determination results, for example: if the confidence of the first determination result is higher than the second determination result, in the second embodiment, if the first determination result is that blocking occurs, the physical layer function module is finally determined to be blocked, and vice versa.
And a third case: both judging results are that no blockage occurs;
And if the first judging result and the second judging result are both that the blocking does not occur, finally judging that the physical layer functional module is not blocked.
The scheme is combined with the base station resources and the functional modules to jointly judge whether the physical layer functional modules are blocked, so that the judging accuracy of the module blocking is improved, the scheduling optimization efficiency of the base station resource scheduling optimization method is improved, and the base station operation efficiency is improved.
The following describes the configuration rule of the resource scheduling priority in detail:
As an optional implementation manner of the above base station resource scheduling optimization method, the configuring, according to a preset priority configuration rule, a resource scheduling priority of the base station resource in the base station chip for the blocking physical layer function module includes: and configuring resource scheduling priority for the physical layer function module with the blockage according to the reported time delay requirement and the blockage degree.
It can be appreciated that the setting of the preset priority configuration rule may consider the reporting delay requirement and the blocking degree of the functional module, for example:
if the reporting time delay requirement of the physical layer functional module is high and the blocking degree is high, configuring the highest resource scheduling priority for the physical layer functional module;
If the reporting delay requirement or the blocking degree of the physical layer functional module is high, configuring a higher resource scheduling priority for the physical layer functional module;
And configuring lower resource scheduling priority for the physical layer functional module under the other conditions.
It can be understood that the resource scheduling priority may be set to multiple levels, for example, 0-3 total four levels, the highest resource scheduling priority is 0 level, the lowest resource scheduling priority is 3 level, and the resource scheduling priority is jointly configured by the comprehensive reporting delay requirement and the module blocking degree.
In addition, it should be noted that the physical layer function modules with the same priority follow the first-in first-out and free competition mode.
According to the scheme, the reporting delay requirement and the blocking degree are comprehensively considered, and the resource scheduling priority of the base station resources in the base station chip is configured for the physical layer functional module with the blocking, so that the physical layer functional module with the blocking can acquire the corresponding base station resources according to the resource scheduling priority configured for the physical layer functional module with the blocking, further deterioration of the blocking condition of the physical layer functional module is avoided, and further improvement of the operation efficiency of the base station is facilitated.
It can be understood that some caches exist in the storage resources of the base station, and the reasonable utilization of the caches can accelerate the processing process of the physical layer functional module, so that the following scheme is provided in the embodiment of the application:
as an optional implementation manner of the above method for optimizing base station resource scheduling, the step S130 allocates base station resources to the physical layer function module according to the resource scheduling priority, including: and allocating a cache for the physical layer functional module with the high resource scheduling priority so as to accelerate the processing process of the physical layer functional module.
It is understood that the Cache may be a Shared Memory, a double rate synchronous dynamic random access Memory DDR, or a Cache Memory Cache.
The scheme for allocating the cache for the physical layer function module with the high resource scheduling priority can be as follows: the read-write addresses of the input buffer and the output buffer of the physical layer function module are configured as cache addresses.
According to the scheme, the high-speed cache in the base station resources is distributed to the physical layer functional module with high resource scheduling priority, so that the processing process of the physical layer functional module is accelerated, the physical layer functional module can rapidly realize the functions to be realized by utilizing the base station resources distributed to the physical layer functional module, and the improvement of the base station operation efficiency is facilitated.
Because Shared Memory is a cache with wider application, is a more efficient access buffer for software and hardware, and is 2-3 times of the access speed of DDR (double data rate synchronous dynamic random access, double data rate synchronous dynamic random access Memory) Memory, the cache in the scheme can adopt Shared Memory, but the size of Shared Memory in a base station Memory resource is limited, generally only 64M byte, which is particularly rare compared with 32768M byte (32G) of DDR Memory, based on the scheme provided by the embodiment of the application, the following scheme is provided:
As an optional implementation manner of the base station resource scheduling optimization method, the allocating a cache for the physical layer function module with a high resource scheduling priority includes: and configuring read-write addresses of the input buffer and/or the output buffer of the physical layer functional module with high resource scheduling priority and the input buffer size and/or the output buffer size meeting the buffer allocation threshold requirement as shared memory addresses.
It will be appreciated that the above cache allocation threshold requirement may be determined based on the allocatable size of the shared memory. In addition, it should be noted that, in order to implement quick start of the multi-cell co-processing system, the multi-cell forward IQ data needs to be preferentially allocated to the shared memory, where the remaining shared memory size is the allocable size of the shared memory.
According to the scheme, the buffer read-write address of the physical layer functional module with high resource scheduling priority and buffer size meeting the buffer allocation threshold requirement can be configured as the shared memory address, so that the shared memory is effectively utilized to accelerate the physical layer functional module, the physical layer functional module can rapidly realize the function to be realized by utilizing the base station resources allocated to the physical layer functional module, and the improvement of the base station operation efficiency is facilitated.
As an optional implementation manner of the base station resource scheduling optimization method, the allocating a cache for the physical layer function module with a high resource scheduling priority includes: determining a target serial processing string according to the resource scheduling priority, the input buffer area, the output buffer area, the buffer allocation threshold and the execution sequence of the physical layer functional module; the buffer memory size required by the serial processing string meets the buffer memory allocation threshold requirement; and configuring read-write addresses of an input buffer area and/or an output buffer area of each physical layer functional module in the target serial processing string as shared memory addresses.
It can be understood that from the buffer multiplexing perspective, the same shared memory may be allocated to different physical layer functional modules for reading and writing, for example, a serial processing string is processed serially according to the sequence of a→b→c, and the output buffer of the physical layer functional module a is the input buffer of the physical layer functional module B, and the output buffer of the physical layer functional module B is the input buffer of the physical layer functional module C, so when the total size of the input buffer, the output buffer, the input buffer and the output buffer of the physical layer functional module a and the input buffer and the output buffer of the physical layer functional module C satisfy the buffer allocation threshold, the read-write addresses of the physical layer functional modules A, B and C are all configured as the shared memory addresses, and the physical layer functional modules A, B and C can be accelerated by a relatively small shared memory cost.
It should be noted that, when the buffer read-write address of each physical layer function module in the target serial processing string is configured as the shared memory address, care should be taken that the read-write operation of each function module will not generate the buffer stepping problem.
According to the scheme, the buffer read-write addresses of the physical layer functional modules in the target serial processing string are configured to be the shared memory addresses, so that multiplexing of the shared memory can be realized, acceleration is performed for the physical layer functional modules, the acceleration effect is maximized, and the base station operation efficiency is improved.
