Fig. 1 is a schematic diagram of an application scenario based on an embodiment of the present disclosure, and as shown in fig. 1, the application scenario shown in fig. 1 may specifically include a user terminal 1 and a coverage hole area 2.
The user terminal 1 may be any terminal capable of accessing a network, and includes but is not limited to a mobile phone, a notebook computer, an intelligent home device, a tablet computer, and other hardware devices capable of sending signaling information.
Specifically, the second signaling information may be sent before the user terminal enters the coverage hole area, and the first signaling information carrying the network attachment signaling may be sent after the user terminal leaves the coverage hole area, i.e., returns to the network.
Example one
Fig. 2 is a flowchart of a method for identifying a coverage hole area according to an embodiment of the present disclosure, and as shown in fig. 2, the method for identifying a coverage hole area according to the embodiment includes the following steps:
The main implementation of the method for identifying a coverage hole area provided in this embodiment is the coverage hole area identification device.
In this embodiment, when the ue enters the coverage hole area, or the ue actively powers off or sets a flight mode to leave the network, and returns to the network again, the ue first sends a first signaling information carrying a network attach signaling (attach signaling). Therefore, the first signaling information carrying the network attachment signaling and the corresponding first time point can be used as a basis for judging the coverage hole area.
Specifically, in order to obtain the first signaling information carrying the network attach signaling and the corresponding first time point, the coverage hole area identifying device may first obtain a historical signaling set corresponding to each user from a database. Specifically, the history signaling set may include all history signaling corresponding to each user and sorted in time order.
102, obtaining target signaling information corresponding to each user from the historical signaling set, where the target signaling information includes a first time point of first signaling information carrying network attachment signaling, a second time point of second signaling information whose time sequence is before the first signaling information, a user identifier of the user, and a cell identifier, and the first signaling information carrying network attachment signaling is a first piece of signaling information after the user returns to the network.
In this embodiment, after the coverage hole area recognition device acquires all the historical signaling in chronological order corresponding to each user from the database, the coverage hole area recognition device may collectively acquire target signaling information corresponding to each user from the historical signaling in order to obtain a time point when the user leaves the network and returns to the network again. Specifically, the target signaling information may include a first time point of first signaling information carrying network attachment signaling, a second time point of second signaling information whose time sequence is before the first signaling information, a user identifier of each user, and a cell identifier.
The first signaling information carrying the network attachment signaling is the first piece of signaling information after the user returns to the network. The second signaling information before the first signaling information in time sequence is the last signaling information before the user leaves the network. Therefore, the first time point corresponding to the first signaling information is a time point when the user returns to the network, and the second time point corresponding to the second signaling information is a time point when the user leaves the network.
In addition, the user identifier of each user may be any identifier capable of uniquely identifying the user identity, for example, the user identifier may be a mobile phone number of the user.
In this embodiment, only the time points when the user leaves the network and returns to the network can be obtained from the signaling information of the user. In order to determine the specific location of the coverage hole area, location information of the user when leaving the network and returning to the network is also required.
Therefore, in order to obtain the location information when the user leaves the network and returns to the network, the coverage hole area identification device may obtain, for each user, a target Measurement Report (MR) corresponding to each user from the database according to the user identifier in the target signaling information.
Specifically, the target measurement report may include a first measurement report after the first time point and a second measurement report before the second time point. That is, the coverage hole area identifying means may acquire a first measurement report after a point in time when the user returns to the network and a second measurement report before a point in time when the user leaves the network.
Since the location information, the time point and the user identification at the time of generating the measurement report can be included in the measurement report. Therefore, the location information when the user generates the first measurement report after the time point when the user returns to the network is considered to be the location information when the user leaves the coverage hole area, and the corresponding time point is the time point when the user leaves the coverage hole area. And generating second measurement report before the time point when the user leaves the network, wherein the position information is the position information when the user enters the coverage hole area, and the corresponding time point is the time point when the user enters the coverage hole area.
In addition, the location information when the measurement report is generated may specifically include latitude and longitude information.
And step 104, performing data processing on the target signaling information corresponding to each user and the target measurement report, and determining a coverage hole area.
In this embodiment, after the coverage hole area identification device acquires the target signaling information and the target measurement report, the coverage hole area identification device may perform data processing on the target signaling information and the target measurement report corresponding to each user in order to accurately identify the coverage hole area from a large amount of information.
In the method for identifying a coverage hole area provided in this embodiment, a historical signaling set corresponding to each user is obtained from a database, target signaling information corresponding to each user is obtained from the historical signaling set, the target signaling information includes a first time point of first signaling information carrying a network attachment signaling, a second time point of second signaling information whose time sequence is before the first signaling information, a user identifier of the user, and a cell identifier, for each user, a target measurement report corresponding to the user is obtained from the database according to the user identifier in the target signaling information, and the target signaling information and the target measurement report corresponding to each user are subjected to data processing to determine the coverage hole area. The coverage hole area is identified more accurately by combining the user signaling information and the measurement report, and the signaling information and the measurement report are subjected to data processing, so that the accuracy and the comprehensiveness of identifying the coverage hole area are further improved, and the technical problem that the identification result is deviated or even wrong in the prior art is effectively solved.
Example two
On the basis of the first embodiment, in order to further explain the coverage hole area identification method provided by the embodiment of the present disclosure, after the step 102 in the first embodiment, the method further includes: judging whether each target signaling message comprises second signaling message carrying a detachment signaling; if the target signaling information exists, the target signaling information comprising the second signaling information carrying the detachment signaling is taken as an abnormal signaling; and deleting the abnormal signaling.
In this embodiment, in order to avoid the interference of the abnormal signaling on the identification of the coverage hole area, the coverage hole area identification device may determine and delete the abnormal signaling.
Specifically, the coverage hole area identifying device may determine whether each target signaling information includes second signaling information carrying detach signaling (detach signaling). The second signaling information carrying the detach signaling is signaling information generated when the user actively shuts down or leaves the network by setting a flight mode, and therefore, the second signaling information cannot be used as signaling information for identifying the coverage hole area.
Therefore, if the coverage hole area identification device determines that the second signaling information carrying the detach signaling exists in the certain target signaling information, the target signaling information can be used as the abnormal signaling, and the abnormal signaling is deleted.
By the method, the target signaling information is effectively judged and eliminated, and the interference of abnormal signaling generated by active shutdown or flight mode setting of a user on the identification of the coverage hole area is avoided.
Further, on the basis of the first embodiment, after the step 102, the method further includes: judging whether each target signaling message comprises a target signaling message of which the time length between the first time point and the second time point exceeds a preset first time length; if yes, the target signaling information of which the time length between the first time point and the second time point exceeds a preset first time length is taken as an abnormal signaling; and deleting the abnormal signaling.
In this embodiment, in order to identify the coverage hole area more accurately, the coverage hole area identification device may determine and delete the signaling with abnormal time.
Specifically, the coverage hole area identifying device may determine whether each target signaling information includes target signaling information in which a time length between the first time point and the second time point exceeds a preset first time length. Because the duration between the first time point and the second time point is the duration that the user leaves the network, the duration between the first time point and the second time point exceeding the preset first duration may be that the user is in the coverage hole area for a long time or other abnormal conditions, and cannot be accurately distinguished, so that the accuracy of identifying the coverage hole area is affected.
Therefore, if the coverage hole area identification device determines that some target signaling information includes target signaling information in which the time length between the first time point and the second time point exceeds the preset first time length, the target signaling information may be used as an abnormal signaling, and the abnormal signaling may be deleted.
The preset first time period may be one hour or other suitable time period.
By the mode, the signaling with abnormal time is effectively judged and eliminated, and therefore the accuracy of identifying the coverage hole area is improved.
Further, on the basis of the first embodiment, after the step 103, the method further includes: for each target measurement report, calculating the moving speed of the user moving from the position corresponding to the first measurement report to the position corresponding to the second measurement report; and if the moving speed is greater than a preset speed threshold value, taking the target measurement report as an abnormal measurement report, and deleting the abnormal measurement report.
In this embodiment, in order to avoid a situation that the position information corresponding to the target measurement report is inaccurate, so as to cause a coverage hole area recognition error, the coverage hole area recognition device may determine and delete the abnormal measurement report by calculating whether the user moving speed is greater than a preset speed threshold.
Specifically, the coverage hole area identification device may calculate, for each user's target measurement report, a moving speed of each user moving from a position corresponding to the first measurement report to a position corresponding to the second measurement report, that is, a moving speed of each user in the coverage hole area. If the coverage hole area identification device judges that the moving speed of a certain user in the coverage hole area is greater than a preset speed threshold value, the preset speed threshold value can be 250km/h, namely the maximum moving speed of a high-speed rail, the moving speed of the user is abnormal, and further the position information corresponding to the target measurement report of the user is inaccurate.
Therefore, if the coverage hole area identification device determines that the moving speed of a certain user moving from the position corresponding to the first measurement report to the position corresponding to the second measurement report is greater than the preset speed threshold, the target measurement report of the user is taken as an abnormal measurement report, and the abnormal measurement report is deleted.
By the mode, the abnormal measurement report is effectively judged and eliminated, so that the condition that the coverage hole area is identified wrongly due to inaccurate position information corresponding to the target measurement report is avoided.
Further, on the basis of the first embodiment, before the step 104, the method further includes: calculating a time point corresponding to the first time point and the first measurement report, and/or whether a difference value between the second time point and a time point corresponding to the second measurement report is greater than a preset second time length; and if so, taking the target signaling information and the target measurement report as abnormal data, and deleting the abnormal data.
In this embodiment, a situation that the coverage hole area is inaccurately identified due to mismatch between a time point corresponding to the target measurement report and a time point corresponding to the target signaling information is avoided. The coverage hole area identification device may determine and delete the abnormal data by calculating whether a difference between a time point corresponding to the measurement report and a signaling time point is greater than a preset second duration.
Specifically, the coverage hole area identifying device may calculate a time point corresponding to a first measurement report after a first time point and a first time point of first signaling information carrying network attachment signaling, and/or whether a difference between a second time point of second signaling information before the first signaling information and a time point corresponding to a second measurement report before the second time point in time order is greater than a preset second duration. Namely, whether the difference between the first time point when the user returns to the network and the time point when the user leaves the coverage hole area is larger than the preset second time length or not and/or whether the difference between the second time point when the user leaves the network and the time point when the user enters the coverage hole area is larger than the preset second time length or not is calculated.
If the difference values are all greater than the preset second time duration, or one of the difference values is greater than the preset second time duration, it indicates that the time point corresponding to the target measurement report is not matched with the signaling time point, that is, the location information corresponding to the target measurement report cannot be used as the location information when the user enters the coverage hole area or when the user leaves the coverage hole area.
Therefore, the coverage hole area identifying device may take the target signaling information and the target measurement report as abnormal data and delete the abnormal data.
Further, the preset second period of time may be 5 minutes or any other suitable period of time.
By the mode, the abnormal data is effectively judged and eliminated, so that the condition that the coverage hole area is inaccurately identified due to the fact that the time point corresponding to the target measurement report is not matched with the time point corresponding to the target signaling information is avoided.
Further, on the basis of the first embodiment, before the step 104, the method further includes: for each user, if a first measurement report before the first time point or a second measurement report after the second time point does not exist in the database, taking the target measurement report as an abnormal measurement report; and deleting the abnormal measurement report.
In this embodiment, it is to avoid that the coverage hole region cannot be accurately identified due to insufficient target measurement report information. The coverage hole area identification device may determine and delete an abnormal measurement report whose information is not complete.
Specifically, the coverage hole area identifying device may determine, for each user, whether a first measurement report before a first time point and a second measurement report after a second time point coexist in the database, and if not, indicate that the target measurement report information is not complete. Therefore, the coverage hole area identification means may regard the target measurement report as an abnormal measurement report and delete the abnormal measurement report.
By the mode, the target measurement report with incomplete information is effectively judged and eliminated, so that the condition that the coverage hole area cannot be accurately identified due to incomplete information of the target measurement report is avoided.
In the coverage hole area identification method provided in this embodiment, by determining whether each target signaling information includes second signaling information carrying a detach signaling, determining whether each target signaling information includes target signaling information in which a time length between a first time point and a second time point exceeds a preset first time length, calculating, for each target measurement report, a moving speed at which the user moves from a position corresponding to a first measurement report to a position corresponding to a second measurement report, calculating a time point corresponding to the first time point and the first measurement report, and/or whether a difference between the second time point and the time point corresponding to the second measurement report is greater than a preset second time length, and for each user, if there is no first measurement report before the first time point or no second measurement report after the second time point in the database, taking the target measurement report as an abnormal measurement report, and deleting the abnormal measurement report. Namely, the abnormal target signaling information and the abnormal target measurement report are judged and deleted, so that the condition that the coverage hole area cannot be accurately identified or the identification error of the coverage hole area is effectively avoided due to the abnormal condition.
EXAMPLE III
Fig. 3 is a flowchart of a method for identifying a coverage hole area according to a third embodiment of the present disclosure, and as shown in fig. 3, the method for identifying a coverage hole area according to this embodiment is further refined in step 104 on the basis of any of the above embodiments, and then the method for identifying a coverage hole area according to this embodiment includes the following steps:
In this embodiment, in order to determine the coverage hole area more accurately, the coverage hole area identification device may perform data processing on the target signaling information and the target measurement report.
Specifically, the coverage hole area identification device may cluster the target signaling information and the target measurement report by using a density clustering algorithm according to the position information of a plurality of preset areas to be measured, so as to obtain the number of users corresponding to each area to be measured and the number of position points corresponding to the measurement report.
The area to be detected is determined as a coverage hole area only when the number of users passing through a certain area to be detected and the number of times of the users passing through the area to be detected both meet certain conditions. Therefore, for each region to be measured, the coverage hole region identification device may determine whether the number of users in the region to be measured is greater than a preset first number threshold, and whether the number of location points corresponding to the measurement report is greater than a preset second number threshold, and if both are greater, it indicates that the region to be measured meets the conditions of the coverage hole region, and may determine that the region to be measured is the coverage hole region.
For example, the coverage hole area identification device may perform clustering on the target signaling information and the target measurement report by using a density clustering algorithm, the clustering radius may be set to 100 meters, and the output area may be used as a preset area to be measured.
