Description
Technical Field
The invention relates to the technical field of wireless communication transmission, in particular to a wireless communication transmission system and a wireless communication transmission method based on multi-base-station cooperation.
Background
At present, along with the construction of urban communication networks, some base stations which are long established at present may not be suitable for the application of the current communication network, and the communication base stations can not be distinguished as urban boundaries in the boundary range of provinces, so that the problem of coverage cell overlapping can be caused no matter the problem caused by urban development construction or the problem that the base stations between adjacent provinces are unreasonable at the boundary of the provinces; when the coverage areas of the base stations are overlapped, the influence of use feeling and even economic loss are often caused to users in the signal coverage area of the base stations, and the similar problem of the base stations is that the initiative of the base stations for judging the operation abnormity is lacked through the feedback after the users are influenced for a long time; in addition, because the data of the user in the coverage area of the base station is huge and the reasons influencing the communication of the user are numerous, it is difficult to effectively judge whether the reason of the communication abnormality of the user is the overlapping coverage of the base station signals in the monitoring area.

calculating the stability r of users in the monitoring area, wherein the larger n1/n0 is, the better the stability of the users in the abnormal communication state is, that is, the greater the relevance between the abnormal communication state of the users and the overlapping coverage range of the base station is, and the smaller the influence of other factors is, the more convincing and effective the data of the users in the influence of the overlapping coverage range of the base station on the users; a1 represents a reference coefficient corresponding to n1/n0, e1 represents that a user records user historical data in a target warning area as a first proportion corresponding to a second index judgment result, e2 represents that the user does not record the user historical data in the target warning area as a second proportion corresponding to the second index judgment result, and e0 represents a mean value of absolute value differences of the first proportion and the second proportion in all user historical data in a monitoring area; the smaller | e1-e2|/e0 is, the smaller the influence of the overlapping coverage of the communication abnormality of the user and the base station is, that is, the communication abnormality of the user has no specific regularity, and the data difference between the user and other users is obvious, so that the data analyzability is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the wireless communication transmission method based on the cooperation of multiple base stations comprises the following steps:
step S1: acquiring a user position and user data of a communication software terminal registered and logged in a monitoring area, wherein the user position refers to a communication position of the communication software terminal when detection is completed in a monitoring period, the user data refers to a communication index result output by the communication software terminal, and the communication index result comprises a first index judgment result when the communication quality is less than a standard value and a second index judgment result when the communication quality is greater than or equal to the standard value; m base stations exist in the monitoring area, and m is a positive integer greater than 1;
the user position indicates the position of the user when the software terminal is used for communication speed measurement; the communication software terminals are all application communication speed measurement software which can be installed on a mobile phone client, the communication index result can be mobile phone signal strength or broadband network speed, when the communication index result is the mobile phone signal strength, the standard value can be set to-95 dbm, and the communication index result of the user is determined to be a second index judgment result by more than or equal to-95 dbm, namely, the communication effect is good; if the actual measurement is-50 dbm, the-50 dbm is greater than-95 dnm, the signal intensity of the mobile phone is better;
step S2: extracting a user corresponding to a first index judgment result when the communication index result is that the communication quality is smaller than a standard value as a target user to be analyzed, acquiring a user position corresponding to the target user to be analyzed, and outputting the user position as the target position to be analyzed; analyzing the target position to be analyzed is to determine reference data of user communication abnormality in a monitoring area with a plurality of base stations, because the reference data of the communication abnormality may be a communication abnormality problem caused by the influence of the plurality of base stations in the monitoring area, and may also be a communication abnormality problem caused by other reasons, and the target position to be analyzed and a user corresponding to the target position to be analyzed are data bases for analyzing which abnormality reason;
and step S3: judging whether the coverage area of a base station in a monitoring area has an overlapping coverage range when the communication software terminal starts to detect in a monitoring period, and transmitting a first early warning signal to the communication software terminal of a target user to be analyzed when the overlapping coverage range does not exist; and when the overlapping coverage range exists, analyzing the relation between the overlapping coverage range and the target position to be analyzed based on historical data, and performing real-time selection early warning.
Whether the area range of the overlapping coverage exists in the monitoring area or not is analyzed because the system needs to determine the reason of the communication abnormity of the user, when the area range of the overlapping coverage does not exist, the fact that the communication abnormity of the user in the monitoring area is irrelevant to the overlapping coverage of the base station can be shown, when the area range of the overlapping coverage exists, the fact that the communication abnormity of the user is possibly relevant to the overlapping coverage of the base station can be shown, therefore, the relation between the communication abnormity and the target position to be analyzed needs to be analyzed subsequently, weighing factors and judgment indexes are determined, and therefore early warning is conducted on the condition that the overlapping coverage of the base station influences the communication of the user. The first early warning signal is an early warning signal which is not related to the overlapping coverage of the base station, for example, the first early warning signal can be a signal which has larger interference at the position where a user is located and has stronger closure of a signal receiving position, such as the position of a basement elevator. And when the communication software terminal of the user starts to detect, the judgment of the overlapping coverage range of the coverage area of the base station is carried out, so that the time length of signal transmission between the user detection and the base station is shortened, and the authenticity and the effectiveness of the analysis of the overlapping coverage range of the base station on the corresponding user detection data are improved.
Analyzing the relation between the overlapping coverage range and the position of the target to be analyzed, comprising the following steps:
step S31: setting an overlapping coverage area in a monitoring area as a target warning area, marking a target user to be analyzed in the target warning area as a first distinguishing user, and acquiring historical data of the first distinguishing user under adjacent interval frequency in the monitoring area, wherein the historical data comprises historical user positions and historical user data;
step S32: setting historical user data of a first distinguishing user as a first index judgment result and judging that the overlapping coverage area exists at present as a first condition, acquiring a historical user position meeting the first condition as a first distinguishing position, and recording the number n1 of times that the first distinguishing position belongs to a target warning area when the position is acquired and the total number n0 of times that the first distinguishing position is acquired when the target warning area exists; using the formula:
calculating the stability r of users in the monitoring area, wherein the larger n1/n0 is, the better the stability of the users in the abnormal communication state is, that is, the greater the relevance between the abnormal communication state of the users and the overlapping coverage range of the base station is, and the smaller the influence of other factors is, the more convincing and effective the data of the users in the influence of the overlapping coverage range of the base station on the users; a1 represents a reference coefficient corresponding to n1/n0, e1 represents that a user records user historical data in a target warning area as a first proportion corresponding to a second index judgment result, e2 represents that the user does not record the user historical data in the target warning area as a second proportion corresponding to the second index judgment result, and e0 represents a mean value of absolute value differences of the first proportion and the second proportion in all user historical data in a monitoring area; the smaller the | e1-e2|/e0 is, the smaller the influence of the communication abnormality of the user and the overlapping coverage of the base station is, that is, the communication abnormality of the user has no specific regularity, and the difference between the data of the user and the data of other users is obvious, so that the analyzability of the data is reduced.
The ratio one and the ratio two can be interpreted as examples as follows: the 10 detection records exist in the user historical data, 4 overlapping coverage areas exist, because the base station analyzes whether the overlapping coverage areas exist or not when the terminal performs communication detection every time, and the second index judgment result shows that the user communication effect is good, namely whether the data of the user has main difference or not is analyzed from another angle; if 6 second index judgment results exist and respectively correspond to 2 times when the historical positions of the 4 times of users belong to the overlapping coverage range and 4 times when the historical positions of the users do not belong to the overlapping coverage range, the proportion I is 2/4, and the proportion II is 4/6;
step S33: setting a stability threshold r0, removing user data with the stability r smaller than the stability threshold r0 in a monitoring area, and calibrating the rest users as target users.
Analyzing the relation between the overlapping coverage range and the position of the target to be analyzed, and further comprising the following steps:
acquiring the number ai1 of target users and the total number ai0 of communication software terminals in a monitoring area for detection when a target warning area exists for the ith time, and the area size si1 of the target warning area and the area size si0 of the monitoring area, wherein i is less than or equal to k, and k represents the total times of detection and existence of the target warning area by the communication software terminals in a monitoring period;
constructing a sequence pair (qi, wi) of a target user, wherein qi represents a target proportion difference index in a monitoring area corresponding to the ith detection, wherein qi = ai1/ai0-ai2/ai0, and ai2 represents the number of users of which the communication index result is a first index judgment result in the target warning area, and the position of the user does not belong to the ith detection;
wi represents the area proportion of a target warning area in the detection area corresponding to the ith detection, and wi = si1/si0;
based on k groups of sequence pairs, performing curve fitting according to sequence points formed by taking an area ratio as an abscissa and a target ratio difference index as an ordinate, extracting sequence points corresponding to a maximum value and a minimum value of the abscissa to connect to form a calibration curve, obtaining a linear distance difference value between the sequence points on the fitting curve and the calibration curve, obtaining the number f1 of the sequence points with the linear distance difference value being less than or equal to a difference threshold value and the number k of all the sequence points, and calculating a fitting ratio d = f1/k, wherein the longitudinal coordinate corresponding to the maximum value of the abscissa is greater than the longitudinal coordinate corresponding to the minimum value of the abscissa;
setting a fitting ratio threshold value d0, if the fitting ratio value d is greater than or equal to the fitting ratio threshold value d0, outputting a first association signal that the overlapping coverage range and the target position to be analyzed have a regular influence on the number of the target position to be analyzed, wherein the first association represents that the change of the overlapping coverage range has a regular influence on the number of the target position to be analyzed, and the regular influence comprises the influence with a mathematical relationship such as linear influence, exponential influence and the like.
The real-time selection early warning method comprises the following steps:
and judging whether a first correlation signal is transmitted in the detection and monitoring area analyzed in real time, and transmitting an early warning signal to the communication software terminal equipment and reminding the user equipment of the influence of the communication abnormity cause of the base station on the overlapping coverage area when the first correlation signal exists or the difference value between the actual target ratio difference index corresponding to the area of the real-time monitoring target warning area and the ideal target ratio difference index corresponding to the area of the target warning area on the fitting curve is less than or equal to a difference threshold value. When the first correlation signal exists, the user data monitored in real time is shown to meet the analyzed fitting curve, namely the abnormal reason of the user communication data under the current detection condition is caused by the overlapping coverage area generated among multiple base stations; the fitted curve shows that there is a correlation between the effects of overlapping coverage of base stations on users.
Judging whether the coverage area of the base station in the monitoring area has an overlapping coverage range, comprising the following steps:
the overlapping coverage range refers to an area affected by the situation that the number of cells with the signal strength difference of less than 6dbm is greater than 3, and the number of the cells comprises the main serving cell.
A cell, also called a cell, refers to an area covered by a base station or a part of a base station in a cellular mobile communication system, in which a mobile station can reliably communicate with the base station through a radio channel. When the overlapping coverage range exists, conditions such as intra-network interference, low cell throughput, poor user perception and the like which affect the use of users can be generated, if a coverage area occurs at a provincial boundary, the risk of automatically switching strong signals can be generated when communication signals of some users only using the provincial mobile network are weaker than those of adjacent provinces at the provincial base station, so that the problems of economic loss and the like of the users are caused, and the problem of overlapping coverage of multiple base stations can be solved by adjusting the downward inclination angle or azimuth angle of the base station to control the coverage range of the base station; the existing network positions an active interference base station through sweep frequency data, and adopts a strategy of replacing or canceling the site address for the site; for the sites which have large influence and cannot be solved by the two methods, the frequency point can be considered to be changed, and after the system receives the analyzed early warning signal, a base station maintenance responsible person carries out professional analysis on the early warning signal, adopts the solution method and carries out maintenance. The overlapping coverage range may be that the communication base station cannot be clearly distinguished as the city boundary, so that the overlapping problem of the coverage cells of the base stations between adjacent provinces may occur at the boundary of the provinces, or the original base station plan may not match the current city state along with the development of the city construction, and the electromagnetic wave refraction problem generated by some newly-built base stations or other newly-added buildings may cause the overlapping of the coverage areas of the existing base stations.
In addition, such problems are often found through active feedback of the user and have already caused losses to many users at this time; the invention carries out early warning analysis on the user on the premise of minimizing loss based on the characteristic judgment about the overlapping coverage range of the historical data analysis, thereby not only shortening the analysis time, but also reducing the influence of artificial uncertainty involved in the historical habit of actively feeding back abnormity by the user to further promote the base station overlapping coverage problem maintenance.
