Description

Method and device for adjusting transmitting power
Technical Field
The present invention relates to a transmission power adjustment technology in the field of mobile communications, and in particular, to a transmission power adjustment method and apparatus.
Background
With the development of broadband Networks and the popularization of Wireless Local Area Networks (WLAN) intelligent terminals, more and more users use WLANs to surf the internet, and the WLAN technology achieves full network coverage of signals by dividing cells to respectively cover. Wherein the coverage of each cell is variable, which is determined by the transmit power of the cell; when the transmitting power of the cell is larger, the coverage area of the cell is correspondingly larger; when the transmission power of a cell is small, the coverage area of the cell is correspondingly small. Thus, when the transmit power of a cell is determined, the coverage of the cell is also determined, within which all users share the network bandwidth. Since users in the coverage area of a cell may change in real time and the service processing capability of the cell is limited, it is likely that the coverage area of the cell is not matched with the service processing capability of the cell as the users in the coverage area of the cell change, and at this time, the coverage area of the cell needs to be adjusted.
For example, when the maximum number of users accessing a certain cell is greatly increased and exceeds the service processing capability of the cell, the transmission power of the cell also needs to be reduced, and then the coverage area of the cell is reduced, so that users of the cell are reduced, congestion is avoided, and user experience is affected, and meanwhile, the transmission power of a relatively idle neighboring cell can be increased, so that the coverage area of the neighboring cell is increased, and the purpose of balancing is achieved; when the maximum number of user accesses in a certain cell is recovered to be equivalent to the service processing capacity of the cell, the transmission power of the cell needs to be recovered.
The existing WLAN transmission power adjusting technology generally adjusts the transmission power of a cell only based on the current adjusting information of the cell, has no prediction capability, can process the cell only when congestion occurs, and has lagged processing response and insufficient intelligence, so that the user experience is poor.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example one
An embodiment of the present invention provides a method for adjusting transmit power, which is described by taking a WLAN cell as an example, and as shown in fig. 1, the method for adjusting transmit power includes:
step 101, acquiring actual adjustment information of a cell in an Nth preset time length, wherein the actual adjustment information comprises an actual maximum user access number.
Illustratively, the WLAN includes a plurality of cells, and full network coverage of signals in the WLAN is achieved by means of coverage of each cell. The user realizes the interaction process with the network by accessing a certain cell. In practical application, due to the movement or departure of a user, the user use condition of a cell may change continuously with time, in order to more conveniently obtain the current user use condition of the cell, the time of day may be first divided into a plurality of preset durations, then the actual maximum user access number is collected and counted within the nth preset duration to obtain the current user use condition of the cell, the preset durations in the day are arranged in sequence according to time, for example, the nth preset duration is the preset duration corresponding to the current time, and the N +1 th preset duration is the next preset duration of the nth preset duration. The preset duration may be set according to specific conditions, which is not limited in the embodiment of the present invention.
In practical applications, it may be inaccurate to reflect the current user usage of the cell only by the actual maximum user access number, for example, there is a case where the user only accesses the WLAN but does not run an application program, at this time, the user equipment only needs to maintain a basic connection service, the traffic of the user is very low, and if only the actual maximum user access number is still considered at this time, misjudgment on the current user usage of the cell may be caused. Therefore, in order to obtain a more comprehensive and accurate current user usage of the cell, the actual adjustment information may further include an actual traffic volume and/or an actual average traffic volume per user. The actual traffic is the total traffic of all users in the preset time period, and can be acquired by collecting and counting in the preset time period. The actual average traffic of a single user indicates the average traffic of each user in a preset time period, and can be obtained according to the actual maximum user access number and the actual traffic.
102, obtaining the prediction adjustment information of the cell in the N +1 th preset time length, wherein the prediction adjustment information comprises the predicted maximum user access number.
In order to adjust the transmitting power of the cell more timely and effectively, the user use condition of the cell in the N +1 th preset time length can be predicted besides the current user use condition of the reference cell, so that the transmitting power of the cell can be adjusted in advance. Similarly, the user usage of the cell in the N +1 th preset time period may not be accurate enough only by predicting the maximum user access number, and therefore, similar to the actual adjustment information, the predicted adjustment information may further include the predicted traffic volume and/or the predicted average traffic volume per user.
Alternatively, the predicted adjustment information may be estimated by a mathematical model based on the actual adjustment information. For example, the predicted maximum user access number may be obtained according to the actual maximum user access number; the predicted traffic can be obtained according to the actual traffic; the predicted average traffic of the single user can be obtained according to the actual average traffic of the single user.
Step 103, adjusting the transmitting power of the cell at least according to the actual maximum user access number of the nth preset time and the predicted maximum user access number of the (N + 1) th preset time.
For example, when the actual maximum user access number of the nth preset duration is less than the first threshold and the predicted maximum user access number of the (N + 1) th preset duration is less than the third threshold, it indicates that the cell is idle, and at this time, the transmission power of the cell may be reduced, so that the cell is more energy-saving and environment-friendly; when the actual maximum user access number of the nth preset time is greater than the fifth threshold and the predicted maximum user access number of the (N + 1) th preset time is greater than the eighth threshold, it is indicated that the number of users in the cell is too many and congestion is likely to occur, and at this time, the transmission power of the cell can be reduced, and the coverage area of the cell is actively reduced, so that the users accessing the cell are reduced, and the occurrence of congestion is avoided; when the actual maximum user access number of the nth preset time duration is greater than or equal to the first threshold and less than or equal to the fifth threshold, and the predicted maximum user access number of the (N + 1) th preset time duration is greater than or equal to the third threshold and less than or equal to the eighth threshold, it is described that the user usage situation at this time of the cell matches with the rated transmission power of the cell, the transmission power of the cell should be recovered to the rated transmission power at this time, and the rated transmission power is the transmission power of the cell when the cell is initialized. It is worth noting that the coverage areas of all cells in the WLAN overlap, so simply reducing the transmission power of a certain cell to make the coverage area of the cell smaller does not usually affect the full network coverage of the signal. In practical applications, the first threshold, the third threshold, the fifth threshold, and the eighth threshold may be set according to specific situations, which is not limited in the embodiment of the present invention. Preferably, the first threshold may be equal to the third threshold, and the fifth threshold may be equal to the eighth threshold.
Therefore, the future prediction adjustment information of the cell is estimated by combining the current actual adjustment information and the historical record, so that the transmitting power of the cell can be adjusted in advance according to the current actual adjustment information and the future prediction adjustment information, the processing response is more timely and intelligent, and the user experience is improved.
Optionally, before obtaining the actual adjustment information of the cell in the nth preset duration, at least a history of a first preset time period needs to be stored; and then, acquiring the historical maximum user access number of the (N + 2) th preset time length of the cell according to the historical record of the first preset time period. When the prediction adjustment information of the cell in the N +1 th preset time duration is obtained, the predicted maximum user access number of the cell in the N +1 th preset time duration may be obtained according to the actual maximum user access number of the N th preset time duration and the history record of the first preset time duration. When the transmission power of the cell is adjusted at least according to the actual maximum user access number for the nth preset time period and the predicted maximum user access number for the (N + 1) th preset time period, it may be first determined whether the actual maximum user access number for the nth preset time period is 0, the predicted maximum user access number for the (N + 1) th preset time period is 0, the historical maximum user access number for the (N + 2) th preset time period is 0, and whether a time period spanned by a historical record is greater than or equal to a first preset time period. When the actual maximum user access number of the nth preset time is 0, the predicted maximum user access number of the (N + 1) th preset time is 0, the historical maximum user access number of the (N + 2) th preset time is 0, and the time period spanned by the historical record is greater than or equal to a first preset time period, adjusting the transmitting power of the cell to be a first transmitting power, wherein the first transmitting power is less than the current transmitting power of the cell.
Illustratively, when the actual maximum user access number of the nth preset time period is 0, the predicted maximum user access number of the N +1 th preset time period is 0, and the historical maximum user access number of the N +2 th preset time period is 0, it indicates that no user access exists in the nth preset time period, the N +1 th preset time period, and the N +2 th preset time period every day for the cell, but if the time period spanned by the history record is too small, for example, only the history record of one day of yesterday, it is determined that no user access exists in the nth preset time period, the N +1 th preset time period, and the N +2 th preset time period every day for the cell, and misjudgment is easily caused, therefore, the embodiment of the present invention further sets the first preset time period, and when the actual maximum user access number of the nth preset time period is 0, the historical maximum user access number of the N +2 th preset time period is obtained from the history record of which is longer than the first preset time period, the predicted maximum user access number of the N +1 th preset time duration is 0, which indicates that the actual maximum user access number of the N th preset time duration is 0, which is a long-term trend, so that the transmitting power of the cell can be adjusted to 0, and the transmitting power of the cell can be adjusted to an extremely low value according to the actual situation, thereby achieving the effect of energy conservation.
Optionally, the actual adjustment information further includes an actual traffic volume of the cell in an nth preset duration, and the predicted adjustment information further includes a predicted traffic volume of the cell in the nth preset duration. Before the adjusting the transmission power of the cell, it is also necessary to obtain the coverage radii of all the neighboring cells of the cell and the distance between each neighboring cell and the cell. When the transmit power of the cell is adjusted at least according to the actual maximum user access number of the nth preset duration and the predicted maximum user access number of the (N + 1) th preset duration, it may be first determined whether the actual maximum user access number of the nth preset duration is less than a first threshold, whether the actual traffic of the nth preset duration is less than a second threshold, whether the predicted maximum user access number of the (N + 1) th preset duration is less than a third threshold, whether the predicted traffic of the (N + 1) th preset duration is less than a fourth threshold, and whether an effective neighboring cell exists. When the actual maximum user access number of the nth preset time is smaller than a first threshold, the actual traffic of the nth preset time is smaller than a second threshold, the predicted maximum user access number of the (N + 1) th preset time is smaller than a third threshold, the predicted traffic of the (N + 1) th preset time is smaller than a fourth threshold, and an effective adjacent cell exists, adjusting the transmitting power of the cell to a second transmitting power, wherein the second transmitting power is smaller than the current transmitting power of the cell, and the coverage radius of the effective adjacent cell is larger than the distance between the effective adjacent cell and the cell.
For example, when the actual maximum user access number of the nth preset time duration is smaller than the first threshold, the actual traffic of the nth preset time duration is smaller than the second threshold, the predicted maximum user access number of the N +1 th preset time duration is smaller than the third threshold, and the predicted traffic of the N +1 th preset time duration is smaller than the fourth threshold, it indicates that the cell has a small traffic at this time, and is relatively idle, and in order to save energy, the transmission power of the cell may be reduced. Since the coverage radius of the effective neighboring cell is greater than the distance between the effective neighboring cell and the cell, the coverage of the effective neighboring cell may substantially include the coverage of the cell. When the effective adjacent cell exists in the cell, the user which can not access the cell can access the effective adjacent cell, so that the network of the user is not interrupted. On the other hand, because the traffic of the cell at this time is not large, reducing the transmitting power of the cell usually does not cause too heavy burden to the effective neighboring cell, and does not cause congestion of the effective neighboring cell, so that the effects of energy conservation and environmental protection can be achieved, and the user experience cannot be influenced. The second threshold and the fourth threshold may be set according to specific situations in practical applications, which is not limited in the embodiment of the present invention. Preferably, the second threshold value may be equal to the fourth threshold value.
Optionally, the actual adjustment information further includes an actual average single-user traffic volume of the cell in an nth preset duration, and the predicted adjustment information further includes a predicted average single-user traffic volume of the cell in the nth preset duration. When the transmission power of the cell is adjusted at least according to the actual maximum user access number for the nth preset time period and the predicted maximum user access number for the (N + 1) th preset time period, it may be first determined whether the actual maximum user access number for the nth preset time period is greater than or equal to a first threshold and less than or equal to a fifth threshold, whether the actual average single-user traffic for the nth preset time period is greater than or equal to a sixth threshold and less than or equal to a seventh threshold, whether the predicted maximum user access number for the (N + 1) th preset time period is greater than or equal to a third threshold and less than or equal to an eighth threshold, and whether the predicted average single-user traffic for the (N + 1) th preset time period is greater than or equal to a ninth threshold and less than or equal to a tenth threshold. When the actual maximum user access number of the nth preset time period is greater than or equal to a first threshold and less than or equal to a fifth threshold, the actual average single user traffic of the nth preset time period is greater than or equal to a sixth threshold and less than or equal to a seventh threshold, the predicted maximum user access number of the (N + 1) th preset time period is greater than or equal to a third threshold and less than or equal to an eighth threshold, and the predicted average single user traffic of the (N + 1) th preset time period is greater than or equal to a ninth threshold and less than or equal to a tenth threshold, adjusting the transmission power of the cell to the rated transmission power.
In general, when a cell uses a rated transmission power, an actual maximum user access number of the cell needs to satisfy a first rated range, and an actual average single-user traffic needs to satisfy a second rated range, for example, the first rated range is greater than or equal to a first threshold and less than or equal to a fifth threshold, and the second rated range is greater than or equal to a sixth threshold and less than or equal to a seventh threshold. Therefore, when the actual maximum user access number in the nth preset time period is greater than or equal to the first threshold and less than or equal to the fifth threshold, and the actual average single-user traffic in the nth preset time period is greater than or equal to the sixth threshold and less than or equal to the seventh threshold, it indicates that the user usage of the cell in the nth preset time period matches the user usage corresponding to the rated transmission power.
When the cell adopts the rated transmission power, the predicted maximum user access number of the cell needs to satisfy a third rated range, and the actual average single-user traffic needs to satisfy a fourth rated range, for example, the third rated range is greater than or equal to a third threshold and less than or equal to an eighth threshold, and the fourth rated range is greater than or equal to a ninth threshold and less than or equal to a tenth threshold. Therefore, when the predicted maximum user access number of the N +1 th preset time duration is greater than or equal to the third threshold and less than or equal to the eighth threshold, and the predicted average single-user traffic of the N +1 th preset time duration is greater than or equal to the ninth threshold and less than or equal to the tenth threshold, it is indicated that the user usage of the cell in the N +1 th preset time duration can be predicted to be matched with the user usage corresponding to the rated transmission power, so that the transmission power of the cell can be recovered to the rated transmission power. In practical application, the fifth threshold, the sixth threshold, the seventh threshold, the eighth threshold, the ninth threshold, and the tenth threshold may be set according to specific situations, which is not limited in the embodiment of the present invention. Preferably, the fifth threshold may be equal to the eighth threshold, the sixth threshold may be equal to the ninth threshold, and the seventh threshold may be equal to the tenth threshold.
Optionally, the actual adjustment information further includes an actual average single-user traffic volume of the cell in an nth preset duration, and the predicted adjustment information further includes a predicted average single-user traffic volume of the cell in the nth preset duration. When the transmission power of the cell is adjusted at least according to the actual maximum user access number for the nth preset time period and the predicted maximum user access number for the (N + 1) th preset time period, it may be first determined whether the actual maximum user access number for the nth preset time period is greater than a fifth threshold, whether the actual average single-user traffic for the nth preset time period is greater than a seventh threshold, whether the predicted maximum user access number for the (N + 1) th preset time period is greater than an eighth threshold, and whether the predicted average single-user traffic for the (N + 1) th preset time period is greater than a tenth threshold. When the actual maximum user access number of the nth preset time is greater than a fifth threshold, the actual single-user average traffic of the nth preset time is greater than a seventh threshold, the predicted maximum user access number of the (N + 1) th preset time is greater than an eighth threshold, and the predicted single-user average traffic of the (N + 1) th preset time is greater than a tenth threshold, adjusting the transmitting power of the cell to a third transmitting power, wherein the third transmitting power is less than the current transmitting power of the cell.
For example, when the actual maximum user access number of the nth preset time duration is greater than the fifth threshold, the actual average single-user traffic of the nth preset time duration is greater than the seventh threshold, the predicted maximum user access number of the (N + 1) th preset time duration is greater than the eighth threshold, and the predicted average single-user traffic of the (N + 1) th preset time duration is greater than the tenth threshold, it indicates that the user access number of the cell is too large, and the average single-user traffic is too large, the cell is likely to be congested, and therefore the transmission power of the cell needs to be reduced, so that the coverage area of the cell is reduced, the access number of the cell users is reduced, and the reduction of user experience due to congestion is avoided.
Optionally, before obtaining the predicted adjustment information of the nth +1 preset duration of the cell, the method further needs to obtain historical adjustment information of the cell at the nth +1 preset duration, historical adjustment information of the cell at the nth preset duration, and historical adjustment information of the cell at the nth-1 preset duration, where the historical adjustment information includes historical maximum user access number. When the predicted adjustment information of the N +1 th preset time length of the cell is obtained, the predicted maximum user access number of the N +1 th preset time length may be obtained according to the historical maximum user access number of the cell in the N +1 th preset time length, the actual maximum user access number of the N-1 th preset time length, the historical maximum user access number of the N-1 th preset time length, and the historical maximum user access number of the N-1 th preset time length.
For example, before obtaining the predicted adjustment information of the cell in the N +1 th preset time period, a history record needs to be stored, where the history record may record the actual maximum user access number of the cell in the nth preset time period each day; then, according to the actual maximum user access number of the cell in the nth preset time every day, obtaining the historical maximum user access number of the cell in the nth preset time every day, wherein it is worth to say that the nth preset time is any one of all preset times in one day of the cell, and therefore, all preset times of the cell in the current day can be sequentially obtained according to the method for obtaining the historical maximum user access number of the cell in the nth preset time every dayHistorical maximum user access number of; next, obtaining the predicted maximum user access number in the N +1 th preset time length according to the historical maximum user access number of the cell in the N +1 th preset time length, the actual maximum user access number in the N-1 th preset time length, the historical maximum user access number in the N-1 th preset time length, and the historical maximum user access number in the N th preset time length, preferably, calculating the predicted maximum user access number in the N +1 th preset time length by a formula (9), wherein the formula (9) isWherein,the predicted maximum user access number for the N +1 th preset duration,predicting the maximum user access number W for the N +1 th preset durationHIn order to be the historical weight value,the actual maximum user access number W of the Nth preset time lengthRAs a result of the current weight value,the actual maximum user access number of the preset time length for the N-1,the predicted maximum user access number for the N-1 th preset duration,and presetting the historical maximum user access number of the duration for the Nth time.
In practical applications, the predicted adjustment information may further include a predicted traffic volume and/or a predicted average traffic volume per user in order to adjust the transmission power more accurately.
For example, similar to the method for obtaining the predicted maximum user access number for the N +1 th preset time duration, the predicted traffic volume for the N +1 th preset time duration may be obtained according to the historical traffic volume of the cell for the N +1 th preset time duration, the actual traffic volume for the N-1 th preset time duration, the historical traffic volume for the N-1 th preset time duration, and the historical traffic volume for the N-1 th preset time duration. Preferably, the predicted traffic volume of the N +1 th preset time period may be calculated by formula (10), where the formula (10) isWherein,the predicted traffic for the N +1 th preset duration,predicting traffic for a preset duration of N +1, WHIn order to be the historical weight value,for actual traffic of Nth preset duration, WRAs a result of the current weight value,actual traffic of a preset duration for the N-1 th time,the predicted traffic for the N-1 th preset duration,and presetting the historical traffic of the duration for the Nth time.
For example, similar to the method for obtaining the predicted maximum user access number for the N +1 th preset time duration, the method may be implemented according to the historical average single-user traffic of the cell in the N +1 th preset time duration, the actual average single-user traffic in the N-1 th preset time duration, or the predicted maximum user access number in the N +1 th preset time durationAnd obtaining the predicted average traffic of the single user in the N +1 th preset time length by the average traffic of the single user in the history in the N-1 th preset time length and the average traffic of the single user in the history in the N +1 th preset time length. Preferably, the predicted average traffic of the (N + 1) th preset time period can be calculated by formula (11), where formula (11) isWherein,predicting the average traffic of the single user for the N +1 th preset time period,predicting the average traffic volume of a single user for a preset duration N +1, WHIn order to be the historical weight value,actual single-user average traffic for Nth preset duration, WRAs a result of the current weight value,actual single-user average traffic for a preset duration of N-1,predicting the average traffic of the single user for the N-1 th preset time length,and averaging the historical single-user average traffic for the Nth preset time length.
Correspondingly, the actual adjustment information may further include actual traffic and/or actual average traffic per user; the historical adjustment information may also include historical traffic and/or historical single-user average traffic.
For example, similar to the method for obtaining the historical maximum user access number of the cell in all the preset durations on the same day, before obtaining the prediction adjustment information of the cell in the N +1 th preset duration, a historical record needs to be stored first, and the historical record can also record the actual traffic volume of the cell in the nth preset duration every day; then, according to the actual traffic volume of the cell in the nth preset time every day, acquiring the historical traffic volume of the cell in the nth preset time every day, wherein it is worth to be noted that the nth preset time is any one of all preset times in one day of the cell, and therefore, the historical traffic volumes of the cell in all preset times every day can be sequentially acquired according to the method for acquiring the historical traffic volume of the cell in the nth preset time every day.
Similarly, before obtaining the prediction adjustment information of the cell in the N +1 th preset time, a history record needs to be stored, and the history record can also record the actual average single-user traffic of the cell in the nth preset time every day; then, the historical single-user average traffic volume of the cell in the nth preset time period on the current day is obtained according to the actual single-user average traffic volume of the cell in the nth preset time period on the current day, and it is worth mentioning that the nth preset time period is any one of all preset time periods in one day of the cell, so the historical single-user average traffic volume of the cell in all preset time periods on the current day can be sequentially obtained according to the method for obtaining the historical single-user average traffic volume of the cell in the nth preset time period on the current day.
The embodiment of the invention provides a method for adjusting transmitting power, which comprises the following steps: acquiring actual adjustment information of a cell in an Nth preset time length, wherein the actual adjustment information comprises an actual maximum user access number; acquiring the prediction adjustment information of the cell in the N +1 th preset time length, wherein the prediction adjustment information comprises the predicted maximum user access number; and adjusting the transmitting power of the cell at least according to the actual maximum user access number of the Nth preset time length and the predicted maximum user access number of the (N + 1) th preset time length. Compared with the prior art, the method estimates the future prediction adjustment information of the cell by combining the current actual adjustment information and the historical record, so that the transmitting power of the cell can be adjusted in advance according to the current actual adjustment information and the future prediction adjustment information, the processing response is more timely and intelligent, and the user experience is improved.
Example two
In the embodiment of the present invention, a processing procedure of a cell monday is taken as an example, where the cell is any one of cells in a WLAN, and specifically, a processing manner of tuesday, wednesday, thursday, friday, saturday, and sunday is the same as that of monday, as shown in fig. 2, the method for adjusting transmission power includes:
step 201, obtaining an initial value of the transmitting power of the cell according to the identifier of the cell and the rated transmitting power record of the cell, and executing step 202.
The cell identifier is unique, so that the cell can be determined by the cell identifier first, and then the nominal transmission power corresponding to the cell identifier in the nominal transmission power record is obtained as the initial value of the transmission power of the cell.
Step 202, judging whether the cell is a cell with adjustable power according to the cell identifier; when the cell is a power adjustable cell, step 203 is executed; when the cell is not a power adjustable cell, step 201 is performed.
In practical applications, there are cells with non-adjustable power, for example, VIP (guest) cells with high network quality requirements, and a constant and relatively large transmission power is generally adopted, and the transmission power of the cells is generally not allowed to be reduced according to actual use conditions, so the embodiment of the present invention does not adjust the transmission power of such cells. The identifier of the cell includes a power adjustable identifier, so that it can be determined whether the cell is a power adjustable cell according to the power adjustable identifier, for example, when the power adjustable identifier is 0, it may indicate that the cell is a power non-adjustable cell, and when the power adjustable identifier is 1, it may indicate that the cell is a power adjustable cell.
Step 203, obtaining the historical maximum user access number, the historical traffic volume and the historical single-user average traffic volume of the cell in each preset time length on the same day according to the actual maximum user access number, the actual traffic volume and the actual single-user average traffic volume of the cell in each preset time length every day in the history record, and executing step 204.
In practical applications, it is generally necessary to combine actual traffic with historical traffic to determine predicted traffic more accurately, and therefore, the determination of historical traffic is crucial to accurately predicting predicted traffic. In order to make the historical traffic more valuable, it is usually necessary to store the actual traffic for each preset time period of each day of the cell in the history. In practical applications, in order to save storage space, the maximum time period spanned by the history record is generally set according to specific situations, for example, the history record of 6 months at most can be stored, and when the history record exceeds 6 months, the initial history record is deleted, so that the maximum time period spanned by the history record is always kept at 6 months.
During initialization, according to the actual traffic of each date corresponding to the current day in the historical record in each preset time, the historical traffic of the cell in each preset time on the current day is sequentially acquired. For example, the description will be given taking an example in which the current day is monday of M months and the maximum time period spanned by the setting history is 6 months, and when M month is 1 month, (M-1) month is 12 months, which indicates the last month of M months.
When the time period spanned by the historical records is less than 1 month, the historical traffic of the Nth preset time length can be obtained according to a formula (1), wherein the formula (1) isWherein,and A is the sum of the actual traffic of the cells in the nth preset time length every day of the last week.
When the time period spanned by the history exceeds 1 month and is less than 2 months, the history can be recordedObtaining the historical traffic of the Nth preset time according to a formula (2), wherein the formula (2) isWherein,and B is the sum of the actual traffic of each Monday cell in the Nth preset time length in M-1 month.
When the time period spanned by the history record exceeds 2 months and is less than 3 months, the history traffic of the nth preset time period can be obtained according to the formula (3), wherein the formula (3) is,wherein,the historical traffic volume of the Nth preset time duration is obtained, B is the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-1 month, and C is the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-2 month.
When the time period spanned by the history exceeds 3 months and is less than 4 months, the history traffic of the nth preset time period can be obtained according to the formula (4), wherein the formula (4) is,wherein,the historical traffic volume of the Nth preset time duration is obtained, B is the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-1 month, C is the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-2 month, and D is the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-3 month.
When the time period spanned by the history exceeds 4 months and is less than 5 months, the nth preset time can be obtained according to the formula (5)Long historical traffic, said equation (5) is,wherein,the historical traffic volume of the Nth preset time duration is set as B, the sum of the actual traffic volumes of each Monday cell of M-1 month in the Nth preset time duration is set as C, the sum of the actual traffic volumes of each Monday cell of M-2 months in the Nth preset time duration is set as D, the sum of the actual traffic volumes of each Monday cell of M-3 months in the Nth preset time duration is set as D, and the sum of the actual traffic volumes of each Monday cell of M-4 months in the Nth preset time duration is set as E.
When the time period spanned by the history exceeds 5 months and is less than 6 months, the history traffic of the nth preset time period can be obtained according to the formula (6), wherein the formula (6) is,wherein,the historical traffic volume of the Nth preset time duration is set as B, the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-1 month is set as C, the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-2 month is set as D, the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-3 month is set as D, the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-4 month is set as E, and the sum of the actual traffic volumes of each Monday cell in the Nth preset time duration in M-5 month is set as F.
When the time period spanned by the history is 6 months, the history traffic of the nth preset time period can be obtained according to formula (7), wherein the formula (7) is,wherein,history traffic of preset duration for NthThe method comprises the following steps of obtaining actual service volume of each Monday cell in M-1 month in the Nth preset time period, obtaining actual service volume of each Monday cell in M-2 month in the Nth preset time period, obtaining actual service volume of each Monday cell in M-3 month in the Nth preset time period, obtaining actual service volume of each Monday cell in M-4 month in the Nth preset time period, obtaining actual service volume of each Monday cell in M-5 month in the Nth preset time period, and obtaining actual service volume of each Monday cell in M-6 month in the Nth preset time period.
It should be noted that, in the embodiment of the present invention, the method for acquiring historical traffic is taken as an example, and the historical maximum user access number, the historical single user average traffic, and the method for acquiring historical traffic are similar, and are not described herein again.
Step 204, determining a historical weight according to the time period spanned by the historical record, and executing step 205.
The time periods spanned by different historical records correspond to different historical weights, and in practical application, because the time periods spanned by the historical records have maximum values, the historical weights also have corresponding maximum values. Specifically, when the time period spanned by the history record does not reach the maximum value, the history weight is in direct proportion to the time period spanned by the history record; when the time period spanned by the history record reaches the maximum value, the history weight also reaches the maximum value corresponding to the history weight and keeps unchanged, in practical application, the proportional relationship can be set according to specific conditions, and the embodiment of the invention is not limited. For example, the maximum value of the time period spanned by the history record may be set to be 6 months, and when the time period spanned by the history record reaches 4 months, the history weight may be 0.4; when the time period spanned by the historical records reaches 5 months, the historical weight can be 0.5; when the time period spanned by the history reaches 6 months, the history weight reaches its maximum value of 0.6 at this point.
Step 205, according to the historical weight, calculating the current weight, and executing step 206.
Specifically, after the historical weight is determined, the current weight may be determined according to a sum of the historical weight and the current weight being 1.
Step 206, obtaining the identifiers and the geographical location information of all the neighboring cells of the cell according to the neighboring cell configuration record, and executing step 207.
The cell has at least one neighboring cell, and the identifiers and the geographical location information of all the neighboring cells of the cell are recorded in the neighboring cell configuration record, wherein the geographical location information indicates the location of the neighboring cell. In practical application, the geographic location information may be represented as longitude and latitude coordinates, or may be represented as a relative location between the neighboring cell and a reference location, where the reference location may be some buildings with identification properties, and may be set according to a specific situation, which is not limited in the embodiment of the present invention.
Step 207, in a second preset time period, determining whether actual maximum user access number information and actual traffic information of an nth preset time length exist; when the actual maximum user access number information and the actual service volume information of the nth preset duration exist, executing step 208; when there is no actual maximum user access number information and actual traffic information for the nth preset duration, step 243 is executed.
In practical application, when the actual maximum user access number information and the actual traffic information of the nth preset time duration are acquired, the acquisition may fail, so that a second preset time duration may be set, and the acquisition operation is monitored in the second preset time duration. When the actual maximum user access number information and/or the actual traffic information of the nth preset time duration are not acquired within the second preset time period, at this time, the transmission power of the cell cannot be adjusted, that is, the acquisition operation is abnormal, and corresponding warning information needs to be generated to inform an administrator, so that the administrator can take corresponding measures in time to correct the abnormal situation, or a correction flow is triggered, so that the correction device can take corresponding measures to correct the abnormal situation. In addition, in practical application, the abnormal condition of the collecting operation further includes that when the actual maximum user access number information and/or the actual traffic information of the nth preset time duration is collected, the messy code information occurs, and at this time, the actual maximum user access number and/or the actual traffic cannot be obtained according to the actual maximum user access number information and/or the actual traffic information, so that corresponding warning information also needs to be generated.
And step 208, acquiring the actual maximum user access number information and the actual service volume information of the nth preset time duration, and executing step 209.
For example, the actual maximum user access number information and the actual traffic volume information of the nth preset time duration may be obtained according to the traffic volume of the nth preset time duration.
Step 209, judging whether the actual maximum user access number of the nth preset duration is within a first preset range; when the actual maximum user access number of the nth preset duration is within the first preset range, executing step 210; when the actual maximum user access number of the nth preset duration is not within the first preset range, step 243 is executed.
For example, when a cell transmits a signal at a rated transmission power, the number of user accesses of the cell is generally between 0 and 800, and even if congestion occurs, the number of user accesses of the cell does not exceed 1000, so that the first preset range may be set to 0 to 1000, and when the obtained actual maximum number of user accesses in the nth preset time period is 1100 or-30, it may be determined that the actual maximum number of user accesses is invalid, and at this time, the transmission power of the cell cannot be adjusted, that is, an abnormal acquisition operation occurs, and a corresponding alarm message needs to be generated, so that the manager is notified that the manager can take a corresponding measure in time to correct the abnormal situation, or a correction flow is triggered, so that the correction device can take a corresponding measure to correct the abnormal situation.
Step 210, judging whether the actual traffic of the nth preset duration is within a second preset range; when the actual traffic volume of the nth preset duration is within the second preset range, executing step 211; when the actual traffic volume of the nth preset duration is not within the second preset range, step 243 is executed.
For example, when a cell transmits a signal at a rated transmission power, the traffic volume of the cell is generally between 0 to 5Gbps (Giga bits per second, 1000 megabits per second), and even if congestion occurs, the traffic volume of the cell does not exceed 6Gbps, so that the first preset range can be set to 0 to 6Gbps, and when the actual traffic volume of the nth preset duration is 7Gbps or-1 Gbps, it can be determined that the actual traffic volume is invalid, and at this time, the transmission power of the cell cannot be adjusted, that is, an abnormal acquisition operation occurs, corresponding alarm information needs to be generated to inform an administrator, so that the administrator can take corresponding measures in time to correct the abnormal situation, or a correction flow is triggered, so that a correction device can take corresponding measures to correct the abnormal situation.
Step 211, calculating the actual average single-user traffic of the nth preset duration according to the actual maximum user access number of the nth preset duration and the actual traffic of the nth preset duration, and executing step 212.
The actual average traffic of the single user in the nth preset time period is represented as the average traffic of each user in the nth preset time period. For example, the actual average traffic volume of a single user for the nth preset time period may be calculated by equation (8). The formula (8) isWherein,for the actual average traffic of the single user of the nth preset duration,the actual traffic for the nth preset duration,and presetting the actual maximum user access number of the duration for the Nth time.
Step 212, according to the historical maximum user access number of the N +1 th preset time length, the historical weight, the actual maximum user access number of the Nth preset time length, the current weight, the actual maximum user access number of the N-1 th preset time length, the historical maximum user access number of the N-1 th preset time length and the historical maximum user access number of the Nth preset time length, the predicted maximum user access number of the N +1 th preset time length is calculated, and step 213 is executed.
For example, the predicted maximum user access number of the N +1 th preset time period may be calculated by equation (9), where equation (9) isWherein,the predicted maximum user access number for the N +1 th preset duration,predicting the maximum user access number W for the N +1 th preset durationHIn order to be the historical weight value,the actual maximum user access number W of the Nth preset time lengthRAs a result of the current weight value,the actual maximum user access number of the preset time length for the N-1,the predicted maximum user access number for the N-1 th preset duration,and presetting the historical maximum user access number of the duration for the Nth time.
Step 213, calculating the predicted traffic of the N +1 th preset duration according to the historical traffic of the N +1 th preset duration, the historical weight, the actual traffic of the Nth preset duration, the current weight, the actual traffic of the N-1 th preset duration, the historical traffic of the N-1 th preset duration and the historical traffic of the Nth preset duration, and executing step 214.
For example, the predicted traffic of the N +1 th preset time period may be calculated by formula (10), where the formula (10) isWherein,the predicted traffic for the N +1 th preset duration,predicting traffic for a preset duration of N +1, WHIn order to be the historical weight value,for actual traffic of Nth preset duration, WRAs a result of the current weight value,actual traffic of a preset duration for the N-1 th time,the predicted traffic for the N-1 th preset duration,and presetting the historical traffic of the duration for the Nth time.
Step 214, calculating the predicted average traffic of the single user for the N +1 th preset time period according to the historical average traffic of the single user for the N +1 th preset time period, the historical weight, the actual average traffic of the single user for the N th preset time period, the current weight, the actual average traffic of the single user for the N-1 th preset time period, the historical average traffic of the single user for the N-1 th preset time period, and the historical average traffic of the single user for the N th preset time period, and executing step 215, 219, 226, or 230.
For example, the predicted average traffic of the (N + 1) th preset time period can be calculated by equation (11), where equation (11) isWherein,predicting the average traffic of the single user for the N +1 th preset time period,predicting the average traffic volume of a single user for a preset duration N +1, WHIn order to be the historical weight value,actual single-user average traffic for Nth preset duration, WRAs a result of the current weight value,actual single-user average traffic for a preset duration of N-1,predicting the average traffic of the single user for the N-1 th preset time length,and averaging the historical single-user average traffic for the Nth preset time length.
It should be noted that, the embodiments of the present invention provide a transmission power adjustment scheme under four conditions, which are respectively a first condition, a second condition, a third condition, and a fourth condition, so that after calculating the predicted average traffic of a single user for an N +1 th preset duration, it is necessary to respectively determine whether the current user usage of a cell meets one of the four conditions. When the current user use condition of the cell meets one of the four conditions, executing a corresponding transmission power adjustment scheme; when the current user usage of the cell does not meet the four conditions, a holding scheme is adopted, for example, the holding scheme may be to hold the current transmission power of the cell. Steps 215, 219, 226, 230 are the initial steps for determining whether the four conditions are met.
Step 215, judging whether the predicted maximum user access number of the N +1 th preset time length is 0; when the predicted maximum user access number of the N +1 th preset duration is 0, executing step 216; when the predicted maximum user access number of the N +1 th preset time period is not 0, step 238 is executed.
When the predicted maximum user access number of the N +1 th preset time length is not 0, it indicates that the current user use condition of the cell does not meet the first condition, and a holding scheme may be adopted.
Step 216, judging whether the actual maximum user access number of the Nth preset time length is 0; when the actual maximum user access number of the nth preset duration is 0, executing step 217; when the actual maximum user access number of the nth preset duration is not 0, step 238 is executed.
When the actual maximum user access number of the nth preset time duration is not 0, it indicates that the current user usage of the cell does not meet the first condition, and a retention scheme may be adopted.
Step 217, judging whether the time period spanned by the history is greater than or equal to a first preset time period; when the time period spanned by the history is greater than or equal to the first preset time period, executing step 218; when the time period spanned by the history is less than the first preset time period, step 238 is performed.
Specifically, when the time period spanned by the history is less than a first preset time period, it indicates that the current user usage of the cell does not meet the first condition, and a retention scheme may be adopted.
For example, the first preset time period may be 3 months.
Step 218, judging whether the historical maximum user access number of the N +2 th preset time length is 0; when the historical maximum user access number of the N +2 th preset time length is 0, executing step 234; when the historical maximum user access number of the N +2 th preset time period is not 0, the step 238 is executed.
For example, when the actual maximum user access number of the nth preset time duration is 0, the predicted maximum user access number of the (N + 1) th preset time duration is 0, the historical maximum user access number of the (N + 2) th preset time duration is 0, and the time period spanned by the historical record is greater than or equal to the first preset time period, the current user usage condition of the cell meets the first condition. Specifically, when the actual maximum user access number of the nth preset time duration is 0, the predicted maximum user access number of the N +1 preset time duration is 0, and the historical maximum user access number of the N +2 preset time duration is 0, it is indicated that no user access exists in the nth preset time duration, the N +1 preset time duration, and the N +2 preset time duration every monday of the cell, but if the time duration spanned by the historical record is too small, for example, only the historical record of one day of the yesterday, it is determined that no user access exists in the nth preset time duration, the N +1 preset time duration, and the N +2 preset time duration every monday of the cell, and thus the misjudgment is easily caused, therefore, the embodiment of the invention further sets the first preset time duration, except that the actual maximum user access number of the nth preset time duration is 0, the predicted maximum user access number of the N +1 preset time duration is 0, besides the maximum historical user access number of the N +2 th preset time length is 0, a closeable scheme can be adopted only when the time period spanned by the historical record is more than or equal to the first preset time period. For example, the closable scheme may be to adjust the transmission power of the cell to 0, or to adjust the transmission power of the cell to an extremely low value according to actual conditions.
When the current user usage of the cell does not meet the first condition, a retention scheme may be adopted.
Step 219, judging whether the actual maximum user access number of the nth preset time length is less than a first threshold value; when the actual maximum user access number of the nth preset time length is less than the first threshold, executing step 220; when the actual maximum number of user accesses for the nth preset time period is greater than or equal to the first threshold, step 238 is executed.
Specifically, when the actual maximum user access number of the nth preset time period is less than the first threshold, it can be reflected that the user access number is smaller and the cell is idle within the nth preset time period; when the actual maximum user access number of the nth preset time duration is greater than or equal to the first threshold, it indicates that the current user usage of the cell does not meet the second condition, and a retention scheme may be adopted.
Step 220, judging whether the actual traffic of the Nth preset time length is smaller than a second threshold value; when the actual traffic volume of the nth preset duration is less than the second threshold, executing step 221; when the actual traffic volume of the nth preset duration is greater than or equal to the second threshold, step 238 is executed.
When the actual traffic of the nth preset time is smaller than the second threshold, it can be reflected that the traffic of the cell is smaller and the cell is idle within the nth preset time; when the actual traffic of the nth preset duration is greater than or equal to the second threshold, it indicates that the current user usage of the cell does not meet the second condition, and a retention scheme may be adopted.
Step 221, judging whether the predicted maximum user access number of the N +1 th preset time length is less than a third threshold value; when the predicted maximum user access number of the N +1 th preset duration is less than the third threshold, executing step 222; when the predicted maximum number of user accesses for the N +1 th preset duration is greater than or equal to the third threshold, step 238 is executed.
When the predicted maximum user access number of the N +1 th preset time length is smaller than the third threshold, the fact that the user access number is smaller and the cell is idle in the N +1 th preset time length can be reflected; when the predicted maximum user access number of the N +1 th preset time length is greater than or equal to the third threshold, it indicates that the current user use condition of the cell does not meet the second condition, and a holding scheme may be adopted.
Step 222, judging whether the predicted traffic of the N +1 th preset time length is smaller than a fourth threshold value; when the predicted traffic volume of the N +1 th preset duration is smaller than the fourth threshold, executing step 223; when the predicted traffic volume for the N +1 th preset time period is greater than or equal to the fourth threshold, step 238 is performed.
When the predicted traffic of the N +1 th preset time duration is smaller than the fourth threshold, it can be reflected that the traffic of the cell is smaller and the cell is idle within the N +1 th preset time duration; when the predicted traffic of the N +1 th preset duration is greater than or equal to the fourth threshold, it indicates that the current user usage of the cell does not meet the second condition, and a retention scheme may be adopted.
Step 223, obtaining the distances between all the neighboring cells and the cell according to the geographical location information of each neighboring cell of the cell, and executing step 224.
Specifically, a first neighboring cell is taken as an example for description, where the first neighboring cell is any one of all neighboring cells of a cell, so that the distance between each neighboring cell of the cell and the cell may be sequentially obtained by referring to the method for obtaining the distance between the first neighboring cell and the cell.
For example, when the geographical location information of the first neighboring cell is represented as a longitude and latitude coordinate, correspondingly, the geographical location information of the cell is also represented as a longitude and latitude coordinate, so that the distance between the first neighboring cell and the cell can be directly obtained according to the two longitude and latitude coordinates; when the geographical position information of the first neighboring cell is represented as the relative position of the first neighboring cell and the reference position, correspondingly, the geographical position information of the cell is also represented as the relative position of the first neighboring cell and the reference position, so that the distance between the first neighboring cell and the cell can be indirectly obtained according to the two relative positions.
And 224, acquiring the coverage radius of all the adjacent cells according to the identifier of each adjacent cell, and executing step 225.
Taking a first neighboring cell as an example for explanation, where the first neighboring cell is any one of all neighboring cells of a cell, and a rated transmit power of the first neighboring cell may be obtained according to an identifier of the first neighboring cell and a rated transmit power record; and then, acquiring the coverage radius of the first adjacent cell according to the rated transmitting power of the first adjacent cell. Since the first neighboring cell is any one of all neighboring cells of the cell, the coverage radii of all neighboring cells can be sequentially obtained with reference to the method for obtaining the coverage radius of the first neighboring cell.
Step 225, judging whether an effective adjacent cell exists; when a valid neighbor exists, perform step 235; when no valid neighborhood exists, step 238 is performed.
Specifically, when the actual maximum user access number of the nth preset time duration is smaller than the first threshold, the actual traffic of the nth preset time duration is smaller than the second threshold, the predicted maximum user access number of the (N + 1) th preset time duration is smaller than the third threshold, the predicted traffic of the (N + 1) th preset time duration is smaller than the fourth threshold, and an effective neighbor exists, the current user usage of the cell meets the second condition, and at this time, the cell is relatively idle and has an effective neighbor, and an energy saving and reduction scheme can be adopted. For example, the energy saving reduction scheme may be to reduce the transmit power of the cell substantially. The transmitting power of the cell is greatly reduced, although most users of the cell can access the effective adjacent cell, because the actual maximum user access number and the actual service volume of the cell are small, the effective adjacent cell is not overloaded, and the congestion of the effective adjacent cell is not caused. Therefore, the emission power of the cell is greatly reduced, so that the effects of energy conservation and environmental protection can be achieved, and the user experience cannot be influenced.
When the current user usage of the cell does not meet the second condition, a retention scheme may be adopted.
Step 226, judging whether the actual maximum user access number of the nth preset time length is greater than or equal to the first threshold and less than or equal to the fifth threshold; when the actual maximum user access number of the nth preset duration is greater than or equal to the first threshold and less than or equal to the fifth threshold, execute step 227; when the actual maximum user access number of the nth preset duration is less than the first threshold or greater than the fifth threshold, step 238 is executed.
When a cell employs a rated transmission power, the actual maximum number of user accesses generally needs to satisfy a first rated range, which may be greater than or equal to a first threshold and less than or equal to a fifth threshold, for example. When the actual maximum user access number of the nth preset time length is greater than or equal to the first threshold and less than or equal to the fifth threshold, the actual maximum user access number of the nth preset time length meets a first rated range; when the actual maximum user access number of the nth preset time duration is less than the first threshold or greater than the fifth threshold, it indicates that the current user usage of the cell does not meet the third condition, and a retention scheme may be adopted.
Step 227, judging whether the actual average single-user traffic of the nth preset duration is greater than or equal to a sixth threshold and less than or equal to a seventh threshold; when the actual average single-user traffic of the nth preset duration is greater than or equal to the sixth threshold and less than or equal to the seventh threshold, execute step 228; when the actual average single-user traffic volume of the nth preset duration is less than the sixth threshold or greater than the seventh threshold, step 238 is executed.
When the cell employs the rated transmission power, the actual average single-user traffic volume generally needs to satisfy the second rated range, for example, the second rated range may be greater than or equal to the sixth threshold and less than or equal to the seventh threshold. When the actual average single-user traffic of the nth preset time length is greater than or equal to the sixth threshold and less than or equal to the seventh threshold, indicating that the actual average single-user traffic of the nth preset time length meets a second rated range; and when the actual average single-user traffic of the nth preset duration is smaller than the sixth threshold or larger than the seventh threshold, indicating that the current user service condition of the cell does not meet the third condition, and adopting a holding scheme.
Step 228, judging whether the predicted maximum user access number of the N +1 th preset time length is greater than or equal to a third threshold value and less than or equal to an eighth threshold value; when the predicted maximum user access number of the N +1 th preset duration is greater than or equal to the third threshold and less than or equal to the eighth threshold, execute step 229; when the predicted maximum user access number of the N +1 th preset time period is less than the third threshold or greater than the eighth threshold, step 238 is executed.
When the cell employs the rated transmission power, the predicted maximum number of user accesses generally needs to satisfy a third rated range, which may be greater than or equal to a third threshold value and less than or equal to an eighth threshold value, for example. When the predicted maximum user access number of the N +1 th preset time length is greater than or equal to the third threshold and less than or equal to the eighth threshold, the predicted maximum user access number of the N +1 th preset time length meets a third rated range; when the predicted maximum user access number of the N +1 th preset time length is smaller than the third threshold or larger than the eighth threshold, it indicates that the current user use condition of the cell does not meet the third condition, and a holding scheme may be adopted. Preferably, the third nominal range may be the same as the first nominal range.
Step 229, judging whether the predicted average traffic of the single user for the N +1 th preset time length is greater than or equal to a ninth threshold and less than or equal to a tenth threshold; when the predicted average traffic volume of the single user for the N +1 th preset duration is greater than or equal to the ninth threshold and less than or equal to the tenth threshold, execute step 236; when the predicted average traffic volume of the N +1 th preset time period is smaller than the ninth threshold or larger than the tenth threshold, step 238 is performed.
For example, when a cell employs a nominal transmit power, the predicted average single-user traffic typically needs to meet a fourth nominal range, which may be greater than or equal to a ninth threshold and less than or equal to a tenth threshold, for example. And when the predicted average traffic of the single user in the N +1 th preset time length is greater than or equal to the ninth threshold and less than or equal to the tenth threshold, indicating that the predicted average traffic of the single user in the N +1 th preset time length meets the fourth rated range.
When the actual maximum user access number of the nth preset time period is greater than or equal to the first threshold and less than or equal to the fifth threshold, the actual average single-user traffic of the nth preset time period is greater than or equal to the sixth threshold and less than or equal to the seventh threshold, the predicted maximum user access number of the N +1 th preset time period is greater than or equal to the third threshold and less than or equal to the eighth threshold, and the predicted average single-user traffic of the N +1 th preset time period is greater than or equal to the ninth threshold and less than or equal to the tenth threshold, the current user usage of the cell meets the third condition, at this time, the current user usage of the cell matches the user usage corresponding to the rated transmission power, a recovery scheme may be adopted, for example, the recovery scheme may be to recover the transmission power of the cell to the rated transmission power.
When the current user usage of the cell does not meet the third condition, a retention scheme may be adopted.
Step 230, judging whether the actual maximum user access number of the nth preset time length is greater than a fifth threshold value; when the actual maximum user access number of the nth preset duration is greater than the fifth threshold, executing step 231; when the actual maximum number of user accesses for the nth preset time period is less than or equal to the fifth threshold, step 238 is executed.
When the actual maximum user access number of the nth preset time is greater than the fifth threshold, it may be reflected that the actual maximum user access number of the cell is too large within the nth preset time, and therefore, congestion may occur in the cell; and when the actual maximum user access number of the Nth preset time length is less than or equal to the fifth threshold, the current user use condition of the cell is not in accordance with the fourth condition, and a holding scheme can be adopted.
231, judging whether the actual average single-user traffic of the Nth preset time length is greater than a seventh threshold value; when the actual average single-user traffic of the nth preset duration is greater than the seventh threshold, executing step 232; when the actual average single-user traffic volume for the nth preset duration is less than or equal to the seventh threshold, step 238 is executed.
When the actual average single-user traffic of the nth preset time is greater than the seventh threshold, it may be reflected that the actual average single-user traffic of the cell is too large within the nth preset time, and therefore the cell may be congested; and when the actual average single-user traffic of the nth preset duration is less than or equal to the seventh threshold, indicating that the current user use condition of the cell does not meet the fourth condition, and adopting a holding scheme.
Step 232, judging whether the predicted maximum user access number of the N +1 th preset time length is greater than an eighth threshold value; when the predicted maximum user access number of the N +1 th preset duration is greater than the eighth threshold, performing step 233; when the predicted maximum user access number of the N +1 th preset time period is less than or equal to the eighth threshold, step 238 is executed.
When the predicted maximum user access number of the N +1 th preset time duration is greater than the eighth threshold, the fact that the predicted maximum user access number of the cell is too large in the N +1 th preset time duration can be reflected, therefore, the cell may be congested in the N +1 th preset time duration, and at the moment, the transmitting power of the cell can be adjusted in advance in the N +1 th preset time duration, so that congestion of the cell is avoided in time, and the method is more intelligent; when the predicted maximum user access number of the N +1 th preset time length is less than or equal to the eighth threshold, it indicates that the current user use condition of the cell does not meet the fourth condition, and a holding scheme may be adopted.
Step 233, judging whether the predicted average traffic of the single user for the N +1 th preset duration is greater than a tenth threshold; when the predicted average traffic volume of the single user for the N +1 th preset duration is greater than the tenth threshold, execute step 237; when the predicted average traffic volume of the single user for the N +1 th preset time period is less than or equal to the tenth threshold, step 238 is executed.
Specifically, when the predicted average traffic of the single user for the N +1 th preset time period is greater than the tenth threshold, it can be reflected that the predicted average traffic of the single user of the cell is too large in the N +1 th preset time period, and therefore the cell may be congested.
When the actual maximum user access number of the nth preset time is greater than the fifth threshold, the actual average single-user traffic of the nth preset time is greater than the seventh threshold, the predicted maximum user access number of the (N + 1) th preset time is greater than the eighth threshold, and the predicted average single-user traffic of the (N + 1) th preset time is greater than the tenth threshold, the current user use condition of the cell meets the fourth condition, at this time, the cell is likely to be congested, so that the transmission power of the cell needs to be reduced, and the coverage of the cell is reducedThe range further reduces the actual maximum user access number and the actual average traffic of a single user, and avoids poor user experience caused by congestion. An overload reduction scheme may be employed, which may be, for example, a suitable reduction in the transmit power of the cell. For example, the current transmit power of the cell is W1At this time, the user usage of the cell meets the fourth condition, and the transmission power of the cell needs to be adjusted to W2. Needs to satisfy the requirement when adjusting the transmitting power of the cell to W2In the meantime, the actual maximum user access number of the cell may be within the first rated range, and the actual average single-user traffic of the cell may also be within the second rated range. The first rated range is the variation range of the actual maximum user access number corresponding to the cell adopting the rated transmitting power, and the second rated range is the variation range of the actual single-user average service volume corresponding to the cell adopting the rated transmitting power.
When the current user usage of the cell does not meet the fourth condition, a retention scheme may be adopted.
Step 234, generating scheme information, wherein the scheme information comprises a closable scheme, and executing step 239.
For example, the closable scheme may be to adjust the transmission power of the cell to 0, or to adjust the transmission power of the cell to an extremely low value according to actual conditions.
Step 235, generating scheme information, wherein the scheme information comprises an energy saving reduction scheme, and step 239 is executed.
For example, the energy saving reduction scheme may be to reduce the transmit power of the cell substantially.
Step 236, generating scheme information, wherein the scheme information comprises a recovery scheme, and executing step 239.
For example, the recovery scheme may be to recover the transmit power of the cell to the nominal transmit power.
Step 237, generating scheme information, wherein the scheme information comprises an overload reduction scheme, and executing step 239.
As an example, the overload reduction scheme may be to reduce the transmit power of the cell appropriately.
Step 238, generating scheme information, wherein the scheme information comprises a maintenance scheme, and executing step 239.
As an example, the holding scheme may be to hold the current transmit power of the cell.
It is worth to be noted that, when the current user usage of the cell does not meet the first condition, the second condition, the third condition, or the fourth condition, the retention scheme is adopted.
239, determining whether the scheme information is successfully generated within a third preset time period; when the generation of the recipe information is successful, step 240 is performed; when the generation of the recipe information is unsuccessful, step 243 is performed.
In practical applications, the generation of the recipe information may fail, and therefore a third preset time period is set to monitor this operation. If the generation of the scheme information fails within the third preset time period, the transmission power of the cell cannot be adjusted, that is, an abnormal operation occurs, corresponding warning information needs to be generated and is notified to an administrator, so that the administrator can take corresponding measures to correct the abnormal condition in time, or a correction flow is triggered, so that the correction device can take corresponding measures to correct the abnormal condition.
Step 240, generating an adjustment instruction according to the scheme information, and executing step 241.
Corresponding to the plan information, the adjustment instructions include a closeable plan adjustment instruction, an energy saving reduction plan adjustment instruction, a recovery plan adjustment instruction, an overload reduction plan adjustment instruction, and a retention plan adjustment instruction.
Specifically, a closable scheme adjustment instruction is generated according to a closable scheme, where the closable scheme adjustment instruction may instruct to adjust the transmission power of the cell to 0, or may instruct to adjust the transmission power of the cell to an extremely low value according to an actual situation; generating an energy-saving reduction scheme adjusting instruction according to the energy-saving reduction scheme, wherein the energy-saving reduction scheme adjusting instruction can indicate that the transmitting power of a cell is greatly reduced; generating a recovery scheme adjusting instruction according to the recovery scheme, wherein the recovery scheme adjusting instruction can instruct to recover the transmitting power of the cell to the rated transmitting power; generating an overload reduction scheme adjusting instruction according to the overload reduction scheme, wherein the overload reduction scheme adjusting instruction can indicate that the transmitting power of the cell is properly reduced; according to the retention scheme, a retention scheme adjustment instruction is generated, which may indicate to maintain the current transmit power of the cell.
Step 241, determining whether the adjusting instruction corresponds to the scheme information; when the adjustment instruction corresponds to the recipe information, performing step 242; when the adjustment instruction does not correspond to the recipe information, step 243 is performed.
In practical applications, the generated adjustment instruction may not correspond to the recipe information, and therefore, it is necessary to monitor whether the generated adjustment instruction corresponds to the recipe information.
Specifically, the method for generating the energy saving reduction scheme adjustment instruction, the recovery scheme adjustment instruction, the overload reduction scheme adjustment instruction, and the retention scheme adjustment instruction is similar to the method for determining the closable scheme adjustment instruction, which is not described herein again. When a closable scheme adjustment instruction is generated, whether scheme information at this time includes a closable scheme needs to be judged; when the scheme information at this time includes a closable scheme, it indicates that the generated adjustment instruction is correct; when the scheme information does not include a closable scheme, it indicates that the generated adjustment instruction is wrong, and at this time, the transmission power of the cell cannot be adjusted, that is, the adjustment operation is abnormal, and a corresponding warning message needs to be generated to notify an administrator, so that the administrator can take a corresponding measure in time to correct the abnormal situation, or a correction flow is triggered, so that the correction device can take a corresponding measure to correct the abnormal situation.
Step 242, according to the adjustment instruction, adjusting the transmission power of the cell, and executing step 207.
The closable scheme adjustment instruction is taken as an example for explanation, and the energy saving reduction scheme adjustment instruction, the recovery scheme adjustment instruction, the overload reduction scheme adjustment instruction, and the retention scheme adjustment instruction are similar to the closable scheme adjustment instruction adjustment method, and are not described herein again. Specifically, the transmission power of the cell is adjusted to 0 according to the instruction of the closable scheme adjustment instruction, or the transmission power of the cell is adjusted to an extremely low value according to the actual situation.
Step 243, generating corresponding alarm information, and executing step 207.
Specifically, when the actual maximum user access number information and the actual traffic volume information do not exist within the second preset time period, generating alarm information without acquiring the actual maximum user access number information and/or the actual traffic volume information within the nth preset time period; when the actual maximum user access number of the Nth preset time length is not in the first preset range, generating alarm information that the actual maximum user access number of the Nth preset time length is abnormal; when the actual traffic of the Nth preset time length is not in the second preset range, generating alarm information of the abnormal actual traffic of the Nth preset time length; when the scheme information is unsuccessfully generated, generating alarm information of failed generation of the scheme information; and when the adjusting instruction does not correspond to the scheme information, generating an error warning message by generating the adjusting instruction.
Compared with the prior art, the method estimates the future predicted adjustment information of the cell by combining the current actual adjustment information and the historical record, so that the transmitting power of the cell can be adjusted in advance according to the current actual adjustment information and the future predicted adjustment information, the processing response is more timely and intelligent, and the user experience is improved; in the method, the actual adjustment information further comprises actual traffic and/or actual average single-user traffic, the predicted adjustment information further comprises predicted traffic and/or predicted average single-user traffic, and the historical adjustment information further comprises historical traffic and/or historical average single-user traffic, so that the user service condition of the cell is reflected more comprehensively and accurately, and the transmitting power of the cell is adjusted more reasonably; in addition, the method also reduces the transmitting power of the relatively idle cell, thereby reducing unnecessary energy consumption and achieving the effects of energy conservation and environmental protection.
