Fig. 1 is a communication management method provided by the present invention, as shown in fig. 1, the method includes:
step S101, collecting system throughput of the wireless communication system working in each collection period in a preset judgment period.
In the embodiment of the present invention, the determination period is a preset time period, and one determination period includes a preset number of acquisition periods, for example, the determination period is 5min, the acquisition period is 1min, and each determination period includes 5 acquisition periods. The wireless communication system is in different working scene modes in the working process according to different scene requirements, wherein the working scene modes are configured with corresponding trigger strategies, and when the wireless communication system meets the trigger strategies, the wireless communication system enters the working scene modes corresponding to the trigger strategies.
It should be noted that, in the working process of the wireless communication system, the system throughput of the wireless communication system is acquired according to the acquisition period in the preset determination period, and the wireless communication system has a corresponding working scene mode in each acquisition period, but the working scene modes of the wireless communication system in each acquisition period are not necessarily the same or different, and the working scene modes are not distinguished by taking the sampling period as an interval, but are different according to the actual scene requirements.
And S102, calculating the average system throughput of each working scene mode contained in the judgment period according to the system throughput of each acquisition period.
And counting the types of the working scene modes contained in all the acquisition periods of the judgment period, and calculating the system average throughput of the working scene modes of different types.
And S103, determining a target working scene mode according to the system average throughput of each working scene mode, wherein the system average throughput of the target working scene mode is more than or equal to the system average throughput of any one working scene mode in a judgment period.
According to the communication management method provided by the invention, the system average throughput of various working scene modes contained in the judgment period is counted, and the target working scene mode which is most suitable for the wireless communication system at present is determined based on the system average throughput, so that the wireless communication system can perform self-adaptive adjustment of the working scene mode switching condition based on the target working scene mode, and the performance of the wireless communication system is further optimized.
Fig. 2 is a flowchart of another communication management method provided by the present invention, as shown in fig. 2, in this embodiment, based on the implementation shown in fig. 1, step S103 is refined, specifically, when at least two working scene modes are included in the determination period, the following step S103a is executed, and when only one working scene mode is included in the determination period, the following step S103b is executed
And step S103a, determining the working scene mode with the maximum system average throughput as a first target working scene mode.
When at least two working scene modes are involved in the judgment period, selecting the working scene mode with the maximum system average throughput from all the working scene modes, wherein the working scene mode with the maximum system average throughput indicates that the performance of the system is currently optimal when the wireless communication system operates in the working scene mode, so that the working scene mode is determined as the target working scene mode to be adjusted, and in order to facilitate subsequent description, the determined target working scene mode is defined as the first target working scene mode.
Step S103b, the trying mechanism is started to control the wireless communication system to work in the test working scenario mode, and when the system average throughput of the wireless communication system working in the test working scenario mode is greater than the system average throughput of the reference working scenario mode, the test working scenario mode is used as the second target working scenario mode, and when the system average throughput of the wireless communication system working in the test working scenario mode is less than or equal to the system average throughput of the reference working scenario mode, the reference working scenario mode is used as the second target working scenario mode.
When only one working scene mode is included in the current judgment period, an attempt of testing the working scene mode can be performed to try to find out whether other working scene modes exist or not, specifically, the wireless communication system is controlled to work in the testing working scene mode, whether the average throughput of the system working in the testing working scene mode is higher than that of the system working in the reference working scene mode or not is compared, when the average throughput of the system working in the testing working scene mode is higher than that of the system working in the reference working scene mode, the system performance of the wireless system working in the testing working scene mode is superior to that working in the reference working scene mode, the testing working scene mode is used as a target working scene mode, and when the average throughput of the system working in the testing working scene mode is compared to be smaller than or equal to that of the reference working scene mode When the throughput is averaged, it is indicated that the performance of the wireless communication system operating in the test operating scenario mode is not improved, and at this time, the reference operating scenario mode in which the wireless communication system previously operates should be taken as the target operating scenario mode. For convenience of the following description, in this case, the determined target working scene mode is defined as the second target working scene mode.
Fig. 3 is a flowchart of another communication management method provided by the present invention, and as shown in fig. 3, in this embodiment, based on the embodiment shown in fig. 2, step S103b may specifically include:
step S10361, detecting whether the wireless communication system has continuously operated in the reference operation scene mode for at least N2 acquisition cycles.
In this embodiment, when it is recognized that only one working scenario mode is included in the current determination period, an attempt to test the working scenario mode may be performed to try to find whether another working scenario mode exists, so as to improve the performance of the wireless communication system.
Specifically, in step S103b1, first, an attempt condition determination of the attempt mechanism is performed, that is, it is determined by detecting whether the wireless communication system has been continuously operated in the reference operation scenario mode for at least N2 acquisition periods, and specifically, when it is detected that the wireless communication system has been continuously operated in the reference operation scenario mode for at least N2 acquisition periods, it indicates that the wireless communication system will be operated in the reference operation scenario mode for a longer time and the system throughput is stable, and then the following step S103b2 may be performed to start the attempt mechanism; when it is detected that the wireless communication system continuously operates in the reference working scene mode for less than N2 acquisition periods, it indicates that the wireless communication system does not stably operate in the reference working scene mode at present, and a subsequent handover may occur.
And step S103b2, controlling the wireless communication system to work in a preset test work scene mode in N3 acquisition cycles.
The test working scenario mode may be preset by a person skilled in the art, that is, the person skilled in the art determines the test working scenario mode corresponding to the reference working scenario mode in advance according to the operation condition of the wireless communication system. The present embodiment initiates the try mechanism by controlling the wireless communication system to operate in the test operating scenario mode for N3 acquisition cycles thereafter.
It should be noted that the values of N2 and N3 are set by those skilled in the art according to actual situations, for example, N2 is 10, N3 is 4, and so on.
Step S10363, counting a system average throughput of the wireless communication system in each acquisition period when the wireless communication system operates in the test operating scenario mode in N3 acquisition periods, which is denoted as a first system average throughput.
Step S103b4, counting the system average throughput of the wireless communication system in each acquisition cycle during N3 acquisition cycles before the wireless communication system operates in the test operating scene mode, which is denoted as the second system average throughput.
When the wireless communication system works for N3 acquisition periods in the test working scene mode, the system average throughput of each acquisition period of the test working scene mode in the N3 acquisition periods is counted, and the system average throughput of N3 acquisition periods of the reference working scene mode before the test working scene mode is selected, so that the reference working scene mode and the test working scene mode are compared conveniently.
And step S103b5, comparing the average throughput of the first system with the average throughput of the second system.
And determining whether the test working scene mode is worth trying or not by comparing the first system average throughput of the test working scene mode with the second system average throughput of the reference working scene mode, thereby determining a target working scene mode which is suitable for the wireless communication system at present, namely a second target working scene mode.
Specifically, if the average throughput of the first system is greater than the average throughput of the second system, it is determined that the system performance of the wireless system in the test working scenario mode is better than the system performance in the reference working scenario mode, that is, the attempt is successful, and at this time, it is determined that the test working scenario mode is the second target working scenario mode, that is, the following step S103b6 is executed; when the average throughput of the first system is less than or equal to the average throughput of the second system, it is determined that the reference operation scenario mode is the second target operation scenario mode, that is, the following step S10367 is executed.
Step S10366, the test working scene mode is used as a second target working scene mode.
Step S10367 is to set the reference operation scene mode as a second target operation scene mode.
After the first target working scene mode and the second target working scene mode are determined, the wireless communication system can perform a series of strategy adjustments according to the target working scene mode so as to ensure and improve the system performance of the wireless communication system in the subsequent working process.
With continued reference to FIG. 3, in some embodiments, after the first target operating scene mode is determined, i.e., after step S103a, the following step S103a1 is performed.
Step S103a1, adjusting the trigger strategy of the first target working scene mode to reduce the trigger difficulty of the first target working scene mode.
In the invention, when the trigger strategy of the first target working scene mode is adjusted, the effect of reducing the trigger difficulty of the first target working scene mode is taken as a standard, namely, the target working scene mode can be more easily switched to in the working process of the wireless communication system. Specifically, how to adjust the trigger policy is not specifically limited in the present invention, for example, in some embodiments, the trigger policy includes: and at least one judgment condition, wherein a corresponding trigger threshold value is configured in the judgment condition, and at the moment, when the trigger strategy of the target working scene mode is adjusted, the judgment condition is realized by adjusting the trigger threshold value configured in the at least one judgment condition in the trigger strategy of the target working scene mode.
In addition, it should be noted that the form of the trigger policy is not limited in the present invention, for example, the trigger policy may include an objective function, and the objective function may be a comprehensive function, or the trigger policy may include a plurality of parallel execution conditions, specifically, when the trigger policy includes an objective function, the determination condition of the trigger policy may be one, that is, as long as the result calculated by using the objective function satisfies the threshold of the determination condition, and when the trigger policy includes a plurality of parallel execution conditions, the determination condition may be a plurality of, that is, when the correlation index of the wireless communication system satisfies the plurality of determination conditions in parallel, the trigger policy is satisfied.
In the invention, the distribution of the working scene modes of the wireless communication system can be divided into two situations, wherein one situation is that the wireless communication system only comprises two working scene modes which are switched according to actual requirements in the working process of the wireless communication system, at the moment, the trigger strategies of the two working scene modes can correspond to the same objective function, but the two working scene modes correspond to different judgment conditions, for example, the judgment condition of one working scene mode is that the calculation result of the objective function is greater than a preset threshold value, the judgment condition of the other working scene mode is that the calculation result of the objective function is less than or equal to the preset threshold value, and when the trigger strategies of the target working scene mode are adjusted in the scene, the common preset threshold value in the judgment conditions of the two working scene modes can be adjusted; in another case, the wireless communication system includes more than two working scene modes, at this time, each working scene mode corresponds to its own objective function, and when the trigger strategy of the target working scene mode is adjusted in this scene, the objective function corresponding to the target working scene mode itself is adjusted.
With continued reference to fig. 3, in some embodiments, after the second target operating scenario mode is determined, two different policy adjustment schemes are implemented according to two scenarios of the second target operating scenario mode.
Specifically, when it is determined that the test operation scene mode is the second target operation scene mode, i.e., after step S103b6, 103b8 is executed, and when it is determined that the reference operation scene mode is the second target operation scene mode, i.e., after step S10367, 103b9 is executed.
Step S103b8, adjusting the trigger strategy of the test working scene mode to reduce the trigger difficulty of the test working scene mode.
The wireless communication system is easier to switch to the test working scene mode in the subsequent working process by adjusting the trigger strategy of the test working scene mode, thereby improving the performance of the system.
And step S103b9, increasing the value of N2 by a preset step value.
The threshold of the trigger attempt mechanism is raised by increasing the value of N2, so that the system can more easily keep operating in the reference working scenario mode to maintain better performance.
It should be noted that, in the embodiment, for the adjustment of the value N2, when the attempt fails, the value N2 should be increased to raise the trigger threshold of the attempt mechanism, and when the attempt succeeds, the value N2 should be restored to the default value to avoid the value N2 being continuously increased.
Fig. 4 is a flowchart of another communication management method provided by the present invention, as shown in fig. 4, on the basis of the embodiment shown in fig. 1, before step S101, the present embodiment further includes:
and S100, determining a working scene mode corresponding to each acquisition period in the judgment period.
In this embodiment, before the system throughput of the wireless communication system in each acquisition period is acquired, the working scene mode of the wireless communication system in each acquisition period may be determined in real time, so as to facilitate subsequent statistics of the accuracy of the system average throughput of different types of working scene modes.
In some embodiments, the corresponding operation scene mode of the wireless communication system in the acquisition period may be determined as follows:
the set acquisition period includes at least N1 sub-periods, each sub-period is a small time segment included in the acquisition period, and the values of N1 and the sub-periods can be set by those skilled in the art according to actual situations, for example, the acquisition period is 1min, N1 is 5, and the sub-period is 1 s.
Specifically, step S100 specifically includes:
step S1001, selecting the first N1 sub-periods of the acquisition period, and determining the working scene mode triggered when the wireless communication system works in each sub-period according to the triggering strategy of each working scene mode and the operation index of the wireless communication system in each sub-period.
Step S1002, determining a working scene mode corresponding to the acquisition period according to a result of the working scene mode triggered by the first N1 sub-periods of the acquisition period.
That is, in each sub-period, acquiring an operation index of the wireless communication system, determining which trigger strategy of the working scene mode the wireless communication system satisfies in each sub-period by using the operation index and the trigger strategies of each working scene mode, when the trigger strategies are satisfied, determining the working scene mode of the wireless communication system in the sub-period, and further determining the working scene mode corresponding to the acquisition period according to a result of the working scene mode triggered by the first N1 sub-periods of the acquisition period, in some embodiments, selecting one working scene mode with the largest frequency from the working scene modes triggered by the first N1 sub-periods of the acquisition period as the working scene mode corresponding to the acquisition period.
Of course, in practical applications, the working scene mode of the acquisition period may also be determined in other manners, and the present invention is not limited in particular.
The following description will use the scenario of TM8 in a wireless communication system as an example.
The TM8 mode supports dual stream data transmission, and even can participate in space division pairing with dual streams, and in principle, the capacity of the system can be greatly increased when RB (Resource Block ) resources are limited, but the performance of TM8 in an actual external field is poor, even worse than TM7, and the main reasons thereof are:
(1) TM8 is short of natural RBs, and due to the conflict between DMRS (Demodulation Reference Signal) of TM8 and PSS (Primary Synchronization Signal), SSS (Secondary Synchronization Signal), PBCH (Physical Broadcast Channel) resources, the available RB resources under some scheduling subframes are reduced.
(2) The DMRS resources of TM8 are limited, and when the number of DMRSs exceeds 4, the DMRS sequences cannot be completely orthogonal, which seriously affects the demodulation performance of TM 8.
(3) Terminals supporting SRS (Sounding Reference Signal) antenna transmission in a real external field are few.
Although TM8 has the above disadvantages, in some specific scenarios, TM8 has a great advantage, and if TM8 gain application scenarios can be quickly and accurately identified and TM8 scheduling is implemented, throughput of the system is greatly improved.
The process of adjusting the TM8 working scene mode by using the communication management method provided by the invention is as follows:
the parameters are set as follows:
large _ Statistics _ window1 (acquisition cycle): 60 s;
small _ Statistics _ window2 (subcycle): 1 s;
selecting the first N1 sub-periods in the acquisition period, wherein N1 is 3;
the number of acquisition cycles N2 included in one judgment cycle is 5;
the trying mechanism judges that the condition N3 is 10;
the preset step value DeltaN3 of N3 is 5;
the trigger strategy for setting the TM8 work scenario mode is as follows:

Wherein TM8_ SU _ SE _ Thr1 is 4.8, and TM8_ SU _ SE _ Thr2 is 6; MU _ TTI _ Stream _ Thr ═ 4; RB _ Rest _ Thr ═ 12.

The triggering strategy is a comprehensive function, the function comprehensively considers space division capacity, Physical Resource Block (PRB) resources and SE distribution of the system, and the application potential of a TM8 specific scene is measured through the indexes, but the function may also consider only part of parameters.
In the first case, the work scene mode in the judgment period is greater than or equal to 2:
step 0: statistics are obtained.
SU_TTI_Ratio：{[0.8，0.7，0.8]，[0.8，0.7，0.8]，[0.5，0.4，0.6]，[0.5，0.4，0.6]，[0.8，0.7，0.8]}n
MU_TTI_Stream：{[3.1，3.2，3]，[3.1，3.2，3]，[4.1，4.2，4]，[3.1，3.2，3]，[3.1，3.2，3]}n
RB_Rest_Ratio：{[0.9，0.7，0.8]，[0.9，0.7，0.8]，[0.9，0.9，0.9]，[0.9，0.7，0.8]，[0.9，0.7，0.8]}n
RBRest_SE_Ratio：{[0.3，0.3，0.4]，[0.3，0.3，0.4]，[0.3，0.3，0.2]，[0.3，0.3，0.4]，[0.3，0.3，0.4]}n
CellThroughput_Large_Statistics_window：{[200]，[200]，[250]，[210]，[200]}n
Note: n represents the nth judgment period; [] Represents one acquisition period within a judgment period, and since N2 is configured with 5, there are 5 acquisition periods, i.e., 5 [ ], within one judgment period.
[ X1, X2, XN1] represents the statistical results of N1 sub-periods in a certain acquisition period, and because N1 is configured with 3, only three sub-periods are counted in each [ ].
Step 1: the TM8 scene quickly identifies the conditional decision.
Equivalent factors corresponding to the sub-periods:
EFI_J＝aI_J*SU_TTI_Ratiol_J*RB_Rest_Ratiol_J*RBRest_SE_Ratiol_J
wherein, I represents an acquisition cycle sequence; j represents the sequence of the corresponding sub-period within the acquisition period. For example:
in the first acquisition period, the equivalent factors corresponding to the first three sub-periods are:
Equivalent-Factor1 ═ EF1_1, EF1_2, EF1_3], where
EF1_1＝1*0.8*0.9*0.3＝0.216；
EF1_2＝1*0.7*0.7*0.3＝0.147；
EF1_3＝1*0.8*0.8*0.4＝0.256。
Step 2: and judging the implementation condition of the scene corresponding strategy.
In Equivalent factors Equivalent-Factor1 corresponding to three sub-periods in the first acquisition period, [ EF1_1, EF1_2, and EF1_3], there are 2 thresholds TM8_ Handover _ Factor (0.15) larger than the trigger policy, and 1 is smaller than the threshold, so the remaining time of the first acquisition period will adopt a TM3/8 adaptive transmission mode, and the working scene mode of the first acquisition period is defined as TM 3/8.
The situation of the remaining 4 acquisition cycles is solved in the same way:
Equivalent-Factor2＝[EF2_1，EF22，EF23]＝[0.216，0.147，0.256]
the second acquisition cycle is defined as TM 3/8;
Equivalent-Factor3＝[EF3_1，EF32，EF33]＝[0，0，0，]
the third acquisition cycle is defined as TM 3/7;
Equivalent-Factor4＝[EF4_1，EF4_2，EF4_3]＝[0.135，0.084，0.192]
the fourth acquisition cycle is defined as TM 3/7;
Equivalent-Factor5＝[EF5_1，EF5_2，EF5_3]＝[0.216，0.147，0.256]
the fifth acquisition cycle is defined as TM 3/8.
Step 3: and counting the system throughput of each acquisition period.
CellThroughput_Large_Statistics_window：{[200]，[200]，[250]，[210]，[200]}n
Note: n represents the nth judgment period.
Step 4: and counting the average system throughput CellThroughput corresponding to different scenes in the judgment period.
Average cellthreughput of three TM3/8 acquisition cycles (200+200+ 200)/3-200;
the average CellThroughput of the two TM3/7 acquisition cycles is (250+210)/2 is 230.
Step 5: based on the average cellthreghhput values corresponding to different scenes counted in Step4, the threshold value TM8_ Handover _ Factor of the trigger strategy in Step1 is intelligently and dynamically adjusted.
The adjustment process is as follows:
average flow rate of TM3/7 in IF determination period > average flow rate of TM3/8 in determination period (Case1)
TM8_Handover_Factor＝TM8_Handover_Factor+TM8_Handover_DeltaFactor＝0.17
Else(Case2)
TM8_Handover_Factor＝TM8_Handover_Factor-TM8_Handover_DeltaFactor＝0.13
End
According to the calculation result, the condition of Case1 is satisfied, so that the result of updating TM8_ Handover _ Factor is 0.17, and the difficulty of TM3/8 scheduling is increased.
In the second case: the method only comprises one working scene mode in a judgment period:
step 0: statistics are obtained.
SU_TTI_Ratio：{[0.8，0.7，0.8]，[0.8，0.7，0.8]，[0.8，0.7，0.8]，[0.8，0.7，0.8]，[0.8，0.7，0.8]}n，{[x，x，x]，[x，x，x]，[]，[]，[]}n+1；
MU_TTI_Stream：{[3.1，3.2，3]，[3.1，3.2，3]，3.1，3.2，3]，[3.1，3.2，3]，[3.1，3.2，3]}n，{[x，x，x]，[x，x，x]，[]，[]，[]}n+1；
RB_Rest_Ratio：{[0.9，0.7，0.8]，[0.9，0.7，0.8]，[0.9，0.7，0.8]]，[0.9，0.7，0.8]，[0.9，0.7，0.8]}n，{[x，x，x]，[x，x，x]，[]，[]，[]}n+1；
RBRest_SE_Ratio：{[0.3，0.3，0.4]，[0.3，0.3，0.4]，[0.3，0.3，0.4]，[0.3，0.3，0.4]，[0.3，0.3，0.4]}n，{[x，x，x]，[x，x，x]，[]，[]，[]}n+1；
CellThroughput_Large_Statistics_window：{[200]，[200]，201]，[199]，[200]}n，{[205]，215]，[]，[]，[]}n+1。
Note: n represents the nth judgment period; []: represents one acquisition period within a judgment period, and since N2 is configured with 5, there are 5 acquisition periods, i.e., 5 [ ], within one judgment period.
[ X1, X2 ], XN1 ]: represents the statistical result of N1 sub-periods in a certain collection period, and because N1 is configured with 3, only the values of three sub-periods are counted in each [ ].
Step 1: the TM8 scene quickly identifies the conditional decision.
EF_n_I_J＝a_n_I_J*SU_TTI_Ration_n_I_J*RB_Rest_Ratio_n_I_J*RBRest_SE_Ration_I_J
Wherein n represents a sequence of judgment periods; i represents the sequence of acquisition cycles; j represents the sequence of the corresponding sub-period within the acquisition period.
In the nth judging period, the equivalent factors of all the acquisition periods are as follows:
equivalent factors corresponding to the first three sub-periods in the first acquisition period
Equivalent-Factor_n_1＝[EF_n_1_1，EF_n_1_2，EF_n_1_3]
EF_n_1_1＝1*0.8*0.9*0.3＝0.216；
EF_n_1_2＝1*0.7*0.7*0.3＝0.147；
EF_n_1_3＝1*0.8*0.8*0.4＝0.256。
Step 2: and judging the implementation condition of the scene corresponding strategy.
2 of the three sub-periods in the first acquisition period are larger than the TM8_ Handover _ Factor (0.15), so the remaining time in the first acquisition period adopts a TM3/8 adaptive transmission mode, and the working scene mode of the first acquisition period is defined as TM 3/8.
The situation of the remaining 4 acquisition cycles is solved in the same way:
Equivalent-Factor_n_2＝[EF_n_21，EF_n_22，EF_n_2_3]＝[0.216，0.147，0.256]
the working scene mode of the second acquisition period is defined as TM 3/8;
Equivalent-Factor_n_3＝[EF_n_3_1，EF_n_3_2，EF_n_3_3]＝[0.216，0.147，0.256]
the third acquisition cycle is defined as TM 3/8;
Equivalent-Factor_n_4＝[EF_n_41，EF_n_4_2，EF_n_43]＝[[0.216，0.147，0.256]
the fourth acquisition cycle is defined as TM 3/8;
Equivalent-Factor_n_5＝[EF_n_5_1，EF_n_5_2，EF_n_5_3]＝[0.216，0.147，0.256]
the fifth acquisition cycle is defined as TM 3/8.
Step 3: and counting the system throughput of each acquisition period.
CellThroughput_Large_Statistics_window：{[200]，[200]，201]，[199]，[200]}n，{[205]，215]，[]，[]，[]}n+1。
Note: n represents the nth judgment period.
Step 4: and counting the average system throughput CellThroughput corresponding to different working scene modes in the judgment period.
Average cellthreughput of five TM3/8 acquisition cycles (200+200+201+199+ 200)/5-200
Step 5: and intelligently and dynamically adjusting the threshold value TM8_ Handover _ Factor of the trigger strategy in Step1 based on the system average throughput corresponding to different working scene modes counted in Step 4.
Specifically, the following is:
step5.1: determine whether TM3/7 trial condition is reached
And judging whether the number of times of continuously adopting the TM3/8 in the acquisition period reaches N3(N3 is equal to 10), if so, performing TM3/7 heuristic, and executing the following Step5.2.
Step5.2: and (3) a TM3/7 heuristic mechanism, namely directly adopting a TM3/7 to perform heuristic scheduling in the first two acquisition periods in the next n +1 th judgment period, and performing throughput statistics after the two acquisition periods.
Step5.3: TM3/7 heuristic result evaluation
The system average throughput for the acquisition period with TM3/7, (205+215)/2, 210;
the system average throughput of the first two TM3/8 acquisition periods closest to the TM3/7 acquisition period is (199+200)/2 is 199.5.
Step5.4: updating threshold value TM8_ Handover _ Factor and heuristic Condition N3 in trigger policy
If: the heuristic is successful, i.e. the system average throughput for the first two acquisition cycles using TM3/8, which is closest to the trial TM3/7 acquisition cycle < the system average throughput for the current two acquisition cycles using TM3/7, then the following operations are performed:
TM8_Handover_Factor＝TM8_Handover_Factor+TM8_Handover_DeltaFactor＝0.17
meanwhile, updating the heuristic conditions: n3, i.e., restore N3 to default;
note: the number of times the TM3/8 is continuously scheduled needs to be counted again from 0.
If: the heuristic fails, i.e., the system average throughput of the first two acquisition cycles employing TM3/8, which are the closest to the attempted TM3/7 acquisition cycle > the system average throughput of the current two acquisition cycles employing TM 3/7;
updating the heuristic conditions: n3, namely setting N3 to N3+ DeltaN 3;
note: the number of times the TM3/8 is continuously scheduled needs to be counted again from 0.
