Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all 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.
Fig. 1 is a schematic flow chart of a signal blind spot positioning method provided by the present invention, and the signal blind spot positioning method shown in fig. 1 includes the following steps:
step S101, determining the off-line user according to the signaling information of the user.
Specifically, signaling information of a user is acquired, where the signaling information includes a measurement report and communication event information, where the measurement report is information on network quality periodically reported to a network by the user and is an important basis for evaluating the quality of a wireless environment, and the communication event information is information on communication events such as a call and an internet access performed by the user.
It should be noted that there are two reporting methods for the measurement report: the method comprises the steps of periodic reporting and event triggering reporting, wherein the reporting mode of the measurement report is configured at the network side and can be configured according to the application scene requirement. In a large city, coverage is generally good, and user density is high, so in order to reduce network stress, a measurement report can be reported in an event-triggered manner. However, in the initial stage of network construction and the debugging and testing operation stage, in order to observe the operation condition of the network at any time, a periodic mode can be adopted to report the measurement report.
In the extracted user signaling data, firstly, a measurement report is utilized to search users which report measurement reports discontinuously, and the period of measurement reports which are not reported by the users which report measurement reports discontinuously is determined, wherein the users which report measurement reports discontinuously are more than the preset time, a preset time range is set, the time can be adjusted according to the network condition, the condition that the measurement reports which are shorter in time are not reported continuously due to building shielding and the like of the users is screened out, and the users which can not report the measurement reports continuously due to the network coverage problem are searched more accurately.
And then, according to the communication event information of the user, determining whether the user which is reported discontinuously is caused by the active shutdown of the user. And determining a shutdown user by searching the last piece of communication event information before the unreported measurement report time period and the first piece of communication event information after the unreported measurement report time period, wherein the shutdown user refers to a user who uses the last piece of communication event information before the unreported measurement report time period as a shutdown message and/or uses the first piece of communication event information after the unreported measurement report time period as a startup message. And determining a offline user according to the discontinuous reporting user and the shutdown user, wherein the offline user is a user after the shutdown user is removed from the discontinuous reporting user.
And step S102, acquiring the offline position and the re-online position of the offline user, and determining the intermediate position of the offline position and the re-online position.
Specifically, according to the location information in the signaling information, the location information of the offline user during offline can be preliminarily determined, and the offline location and the re-access location of the offline user can be determined by using the location information reported in the communication event of the user, the GPS positioning information and the like. Because the distance between the off-line position and the re-on-line position of the off-line user is different, when a plurality of users are counted, the intermediate point position of the off-line position and the re-on-line position is used as the off-line position of the off-line user, so that the workload of analysis is reduced more, and the analysis result is more accurate.
And step S103, determining a blind area set according to the middle point position of each off-line user.
Specifically, according to a preset coverage range, clustering statistics is performed on the positions of the intermediate points of the off-line users, and an intermediate point set is obtained. The preset coverage range needs to be set according to the actual condition of the network, for example, in a user dense area, the quality of the network coverage needs to be higher, a smaller coverage range can be set, and for example, in an area with fewer users, a larger coverage range can be set if a certain coverage quality needs to be achieved. And in a preset coverage range, performing cluster statistics on the positions of the intermediate points of the off-line users to serve as an intermediate point set. The clustering statistics can be performed by a common clustering algorithm.
The blind area set is a set of intermediate points of which the number of the intermediate points is greater than a preset first threshold, in the intermediate point set, a certain threshold needs to be set, more areas of the intermediate points are found out for statistics, if the number of the intermediate points in one area is greater than 3, the intermediate points are used as statistical objects, the phenomenon of network disconnection caused by other non-network coverage reasons of a single user is avoided, if network disconnection caused by transient mobile phone faults and the like occurs, the areas of which the positions of the intermediate points are concentrated are found out and used as further analysis objects, and the accuracy of blind point positioning is improved.
And step S104, determining signal blind spots according to the position distribution condition of each intermediate point in each blind zone set.
Specifically, after the intermediate point set is determined, the determining a signal blind point according to the position distribution of the intermediate point in the blind area set includes:
specifically, after a blind area set meeting a certain intermediate point number condition is determined, in order to enable the positioning of the blind points to be more accurate, three intermediate points are randomly extracted from the blind area set to form a triangle; and determining the inner center of the triangle as a signal blind spot. In an actual network, blind areas possibly caused by one signal blind point have a certain coverage range, and the three adjacent intermediate points are utilized to further perform correlation analysis on the position relationship between the three adjacent intermediate points, so that the uncertainty of a blind area set searched by a single user can be eliminated, and the signal blind points further positioned by at least three users can be closer to the position of the actual signal blind point.
The signal blind area positioning method provided by the invention can position the off-line user according to the signaling data, determine the area with more off-line users in the preset coverage area as the signal blind area, and further accurately position the signal blind point by analyzing the middle point of the off-line user off-line position in the blind area, so that operators reduce the labor and material resource expenditure for daily signal blind point positioning work, can conveniently, timely and accurately position the signal blind point in the daily network, and improve the network coverage quality.
