It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a schematic flow chart of a number identification method provided in an embodiment of the present invention, where the embodiment is applicable to a case of identifying a target number in a batch number, especially to a case of dialing a virtual device, and is applicable to a case of identifying a target number of a machine-card separation type, and the method may be performed by a number identification device, which may be implemented in a software and/or hardware manner, and the number identification device may be integrated in an electronic device such as a computer or a server.
As shown in fig. 1, the method of the present embodiment includes:
s110, acquiring original signaling data, and extracting authentication data corresponding to at least one number to be detected in the original signaling data.
The original signaling data may be signaling data to be processed at the current time. The raw signaling data may include, but is not limited to, the following: number to be detected, authentication data, location coding and cell identification. The number to be detected may be a number which needs to be identified at the current time. Authentication data may include, but is not limited to, the following: the number of authentications, an authentication start time point corresponding to each authentication, and an authentication completion time point corresponding to each authentication.
Specifically, the original signaling data within the preset duration may be obtained. Furthermore, the number to be detected and the authentication data corresponding to the number to be detected in the original signaling data can be extracted.
Alternatively, there may be various manners of acquiring the original signaling data, which are not limited herein, for example, acquiring the signaling data from an operation domain, or acquiring the signaling data from a base station, or receiving the signaling data sent by a server, or acquiring the signaling data from an international gateway.
S120, determining authentication delay data corresponding to each number to be detected according to the authentication data of each number to be detected.
The authentication delay data may be authentication delay data obtained according to authentication data of the number to be detected.
Specifically, after the authentication data of each number to be detected is obtained, the authentication delay data corresponding to each number to be detected can be determined according to the authentication data of each number to be detected.
Optionally, the authentication delay data corresponding to each number to be detected is determined according to the authentication data of each number to be detected by the following steps:
step one, for each authentication of each number to be detected, calculating a difference value between an authentication starting time point of the current authentication of the current number to be detected and an authentication finishing time point to obtain a single authentication time delay of each authentication of each number to be detected.
The single authentication delay can be understood as one authentication delay of the number to be detected.
Specifically, for each authentication of each number to be detected, the current number to be detected may be determined. After determining the current number to be detected, an authentication start time point and an authentication completion time point of the current authentication of the current number may be determined. After determining the authentication starting time point and the authentication finishing time point of the current authentication of the current number, the difference value calculation can be carried out on the authentication starting time point and the authentication finishing time point of the current authentication of the number to be detected, and then, the single authentication time delay of each authentication of each number to be detected can be obtained.
For example, the current number to be detected is 10 minutes and 20 seconds at 9 am on 10 month 01 of 2020, and the current number to be detected is 9 minutes and 23 seconds at 9 am on 10 month 01 of 2020, and then the single authentication delay of the current number to be detected on the first authentication is a time difference between 9 minutes and 23 seconds at 9 am on 10 month 01 of 2020 and 10 minutes and 20 seconds at 9 am on 10 month 01 of 2020, that is, the single authentication delay of the current number to be detected on the first authentication is 3 seconds.
And step two, calculating an authentication delay average value of each number to be detected according to the authentication times of each number to be detected and the single authentication delay of each authentication, and taking the authentication delay average value as authentication delay data corresponding to each number to be detected.
Specifically, after obtaining the single authentication time delay of each authentication of each number to be detected, the average value of the authentication time delays of each number to be detected can be calculated according to the authentication times of each number to be detected and the single authentication time delay of each authentication, and then the average value of the authentication time delays of each number to be detected can be obtained, so that the average value of the authentication time delays of each number to be detected can be used as the authentication time delay data corresponding to each number to be detected.
For example, the number of times of authentication of the current number to be detected is 3 times, the authentication time delay of the current number to be detected at the 1 st time is 3 seconds, the authentication time delay of the current number to be detected at the 2 nd time is 1 second, and the authentication time delay of the current number to be detected at the 3 rd time is 2 seconds, so that the average value of the authentication time delays of the current number to be detected can be obtainedSecond, namely, the authentication delay data of the current number to be detected is 2 seconds.
S130, according to the authentication delay data of each number to be detected, grouping processing is carried out on each number to be detected, and a number group to be detected is obtained.
The number group to be detected may be a number group obtained by grouping each number to be detected. The number of sets of numbers to be detected may be one or more. The number of numbers to be detected included in the group of numbers to be detected may be one or more.
Specifically, for the authentication delay data of each number to be detected, packet processing can be performed on each number to be detected, and then, a number group to be detected can be obtained.
S140, determining a target detection number group in the number group to be detected, and determining target numbers according to each number to be detected in the target detection number group.
The target detection number group may be a number group obtained by analyzing authentication delay data corresponding to each number to be detected included in the number group to be detected. The number of sets of object detection numbers may be one or more. The destination number may be understood as an abnormal type number.
Specifically, the authentication delay data corresponding to the number to be detected in each number group to be detected can be analyzed, and then, the target detection number group in the number group to be detected can be determined. After determining the target detection number group in the number group to be detected, the call behavior characteristic data corresponding to each number to be detected in the target detection number group can be analyzed, and then the target number can be determined.
It should be noted that, the number of the target detection number groups is smaller than or equal to the number of the number groups to be detected.
Optionally, the target detection number group in the number group to be detected may be determined by the following steps:
step one, determining the average authentication delay of the number groups to be detected according to the authentication delay data corresponding to the numbers to be detected in the number groups to be detected aiming at each number group to be detected.
Specifically, for each number group to be detected, the average authentication delay of the number group to be detected can be determined according to the authentication delay data corresponding to each number to be detected in the number group to be detected.
Optionally, the average authentication delay of the number group to be detected may be determined according to authentication delay data corresponding to each number to be detected in the number group to be detected by:
and summing the authentication delay data corresponding to each number to be detected in the number group to be detected to obtain authentication delay data and value corresponding to the number group to be detected, and dividing the authentication delay data and value by the number of the numbers to be detected included in the number group to be detected to obtain the average authentication delay of the number group to be detected.
The current number group to be detected includes 3 numbers to be detected, wherein the 3 numbers to be detected are number 1, number 2 and number 3 respectively. The authentication delay data corresponding to the number 1 is 2 seconds, the authentication delay data corresponding to the number 2 is 3 seconds, and the authentication delay data corresponding to the number 3 is 1 second, so that the sum of the authentication delay data corresponding to the number group to be detected is 2+3+1=6 seconds, and further, the average authentication delay of the number group to be detected can be 6/3=2 seconds.
And step two, if the average authentication time delay of the number group to be detected reaches a preset time delay threshold, taking the number group to be detected as a target detection number group.
The delay threshold may be empirically set, and the specific value thereof is not limited herein, for example, the pre-delay threshold is 2 seconds, 3 seconds, or 4 seconds.
Specifically, a time delay threshold is preset, and if the average authentication time delay of the number group to be detected reaches the preset time delay threshold, the number group to be detected can be used as the target detection number group.
Illustratively, the preset delay threshold is 2 seconds. The number groups to be detected are a first group of number groups to be detected and a second group of number groups to be detected, wherein the average authentication time of the first group of number groups to be detected is 1 second, and the average authentication time of the second group of number groups to be detected is 3 seconds. It can be seen that the average authentication of the first group of to-be-detected number groups does not reach 2 seconds for 1 second, and the average authentication of the second group of to-be-detected number groups reaches 2 seconds for 2 seconds, so that the second group of to-be-detected number groups is the target detection number group.
Optionally, determining the target number according to each number to be detected in the target detection number group includes: and extracting call behavior characteristic data of each number to be detected in the target detection number group, and determining the target number according to the call behavior characteristic data of each number to be detected.
The call behavior feature data may include at least one of feature data such as call times, calling duty ratio, opposite terminal number dispersion, and opposite terminal home location duplicate removal amount.
Specifically, call behavior feature data of each number to be detected in the target detection number group can be extracted, further, at least one call behavior feature data of each number to be detected is analyzed, and the target number is determined based on an analysis result.
Optionally, determining the target number according to the call behavior feature data of each number to be detected includes: extracting the number of calls of a target number, the calling duty ratio, the number dispersion of the opposite terminal and the characteristic data of the duplicate removal quantity of the attribution of the opposite terminal in a preset period; and determining the target number according to the call times, the calling duty ratio, the opposite terminal number dispersion and the opposite terminal attribution deduplication quantity characteristic data of the target number.
Optionally, the target number may be determined according to the number of calls, the calling duty ratio, the opposite terminal number dispersion, and the opposite terminal home location deduplication number feature data of the target number by:
the number of calls threshold, the calling duty ratio threshold, the opposite terminal number dispersion threshold and the opposite terminal home location duplication removal number threshold can be preset, if the number of calls of the number to be detected reaches the number of calls threshold, the calling duty ratio of the number to be detected reaches the calling duty ratio threshold, the opposite terminal number dispersion of the number to be detected reaches the opposite terminal number dispersion threshold, and the opposite terminal home location duplication removal number of the number to be detected reaches the opposite terminal home location duplication removal number threshold, the number to be detected can be used as a target number.
In order to further improve the efficiency and accuracy of the number identification, after the target number is determined, the maximum time advance corresponding to the target number can be obtained from the original signaling data, and further, the number processing can be performed on the target number according to the maximum time advance corresponding to the target number. The number processing may be a reserved number or a deleted number.
According to the technical scheme, the authentication data corresponding to at least one number to be detected in the original signaling data are extracted by acquiring the original signaling data; according to the authentication data of each number to be detected, determining authentication delay data corresponding to each number to be detected; according to the authentication delay data of each number to be detected, carrying out grouping processing on each number to be detected to obtain a number group to be detected; the technical scheme of the embodiment of the invention determines the target number according to each number to be detected in the target detection number group, determines the authentication delay data of the number to be detected through the authentication data of the number to be detected in the original signaling data, and identifies the target number based on the authentication delay data without depending on the identification of dialing equipment.
Example two
Fig. 2 is a flow chart of a number identification method according to a second embodiment of the present invention, and based on the foregoing embodiment, optionally, the grouping processing is performed on each number to be detected according to authentication delay data of each number to be detected, so as to obtain a number group to be detected, including: arranging the authentication delay data of each number to be detected according to a preset arrangement sequence, determining the number of the number to be detected corresponding to each authentication delay data after arrangement, and obtaining a number sequence of the number arranged according to the preset arrangement sequence, wherein the preset arrangement sequence is from big to small or from small to big; and carrying out grouping processing on each number to be detected according to the variation trend of the number in the number sequence to obtain a number group to be detected.
Wherein, the technical terms identical to or corresponding to the above embodiments are not repeated herein.
As shown in fig. 2, the method of this embodiment may specifically include:
s210, acquiring original signaling data, and extracting authentication data corresponding to at least one number to be detected in the original signaling data.
S220, determining authentication delay data corresponding to each number to be detected according to the authentication data of each number to be detected.
S230, arranging the authentication delay data of each number to be detected according to a preset arrangement sequence, and determining the number of the numbers to be detected corresponding to each authentication delay data after arrangement to obtain a number sequence of the number arranged according to the preset arrangement sequence.
The preset arrangement sequence can be from big to small or from small to big.
Specifically, after the authentication delay data corresponding to each number to be detected is obtained, the arrangement sequence of the authentication delay data of each number to be detected can be preset. The authentication delay data of each number to be detected is arranged according to a preset arrangement sequence, and then the number of the numbers to be detected corresponding to each authentication delay data after arrangement can be determined. After the number of the numbers to be detected corresponding to each authentication delay data after arrangement is determined, a number sequence of the number of the numbers arranged according to a preset arrangement sequence can be obtained.
For example, the authentication delay data of the number to be detected 1 is 2 seconds, the authentication delay data of the number to be detected 2 is 2 seconds, and the authentication delay data of the number to be detected 3 is 3 seconds. And arranging the authentication delay data of each number to be detected from small to large, wherein the number of numbers with the authentication delay data of 2 seconds is 2, and the number of numbers with the authentication delay data of 3 seconds is 1. Therefore, the number sequence of the number arranged according to the arrangement sequence from small to large can be obtained, wherein the number sequence is 2 seconds of authentication delay data and the authentication delay data is 3 seconds.
S240, according to the variation trend of the number in the number sequence, grouping processing is carried out on each number to be detected, and a number group to be detected is obtained.
The change trend may be a trend of the number and the authentication delay data, alternatively, the change trend may be a trend of the number changing from small to large with the authentication delay data, or the change trend may be a trend of the number changing from large to small with the authentication delay data.
Specifically, after a number sequence of numbers arranged according to a preset arrangement order is obtained, a change trend of the numbers in the number sequence can be determined. Furthermore, each number to be detected can be subjected to grouping processing according to the changing trend of the number in the number sequence, and then the number group to be detected can be obtained.
Optionally, the number to be detected may be grouped according to a variation trend of the number in the number sequence to obtain a number group to be detected:
step one, determining the inflection point position in the variation trend of the number in the number sequence, and taking authentication delay data corresponding to the number at the inflection point position as grouping reference data.
The inflection point position may be a position of an inflection point in a trend of a number of numbers in the number sequence. The number of corner points may be one or more. The packet reference data may be reference data for grouping the numbers to be detected. The number of packet reference data may be one or more.
Specifically, after determining the trend of the number of numbers in the number sequence, the inflection point position in the trend of the number of numbers in the number sequence may be determined according to the trend of the number of numbers in the number sequence. After determining the inflection point location, authentication delay data corresponding to the number located at the inflection point location may be used as the packet reference data.
It should be noted that, considering that the authentication delay data and the number of numbers are often discrete data, the number of numbers located at the inflection point position may be understood as the number of numbers located adjacent to the inflection point position. The packet reference data may select one of the authentication delay data corresponding to one of the two critical number numbers whose trend changes from an increasing trend to a decreasing trend or from a decreasing trend to an increasing trend as the packet reference data.
By way of example only, and not by way of limitation,
TABLE 1
T 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160
S 10 15 20 25 20 15 10 15 20 25 20 15 5 4 10 15
Table 1 is a trend of the number and the authentication delay data, where T represents the authentication delay data and S represents the number. Alternatively, (t=40, s=25) in the variation trend is taken as one inflection point position, that is, inflection point position 1; (t=70, s=10) as one inflection point position, namely, inflection point position 2; (t=100, s=25) as one inflection point position, namely, inflection point position 3; (t=140, s=4) as one inflection point position, that is, inflection point position 4. Then t=40 can be taken as one packet reference data, i.e. packet reference data 1; let t=70 be one packet reference data, i.e., packet reference data 2; t=100 as one packet reference data, i.e., packet reference data 3; t=140 as one packet reference data, i.e., packet reference data 3.
Dividing the number to be detected corresponding to each authentication delay data into at least two primary number groups based on the packet reference data, and determining the number groups to be detected based on the at least two primary number groups.
The primary number group may divide the number to be detected corresponding to each authentication delay data according to the packet reference data.
Specifically, after the packet reference data is obtained, the number to be detected corresponding to each authentication delay data may be divided based on the packet reference data, and then at least two primary number groups may be obtained. After obtaining at least two primary number groups, the obtained primary number groups can be processed, and then the number groups to be detected can be obtained. Alternatively, the obtained primary number groups may be subjected to a combination process.
Optionally, the number to be detected corresponding to each authentication delay data may be divided into at least two primary number groups based on the packet reference data by:
dividing a quantity sequence into at least two quantity intervals by taking each group of reference data as a critical point of the quantity interval.
The number interval may be a monotonically increasing interval or a monotonically decreasing interval.
Specifically, each group of reference data is used as a critical point of a number interval, so that the number sequence can be divided, and at least two number intervals can be obtained.
And secondly, taking the arrangement sequence of the authentication time delay data as the dividing sequence of the primary number groups, and determining each number interval or every two adjacent number intervals as a primary number group.
Specifically, by taking the arrangement sequence of the authentication delay data as the division sequence of the primary number groups, each number interval or every two adjacent number intervals can be determined as one primary number group.
Along the lines of the above example, with continued reference to table 1, packet reference data may be obtained as: packet reference data 1 (t=40), packet reference data 2 (t=100), and packet reference data 3 (t=140). Then, the number sequence numbers corresponding to t=10 to t=40 are taken as one number section, i.e., number section 1; taking the number sequence numbers corresponding to t=50 to t=70 as one number interval, namely a number interval 2; taking the number sequence numbers corresponding to t=70 to t=100 as one number interval, namely a number interval 3; taking the number sequence numbers corresponding to t=100 to t=140 as one number interval, namely a number interval 4; the number sequence numbers corresponding to t=150 to t=160 are taken as one number section, i.e. number section 5.
Then, the number interval 1, the number interval 2, the number interval 3, the number interval 4, and the number interval 5 may be individually used as one primary number group, or the number interval 1 and the number interval 2 may be used as one primary number group, the number interval 3 and the number interval 4 may be used as one primary number group, and the number interval 5 may be used as one initial number group. Alternatively, the number set to be detected may be determined based on at least two primary number sets by:
And aiming at each primary number group, if the total number of the numbers to be detected contained in the primary number group reaches a preset number threshold, taking the primary number group as the number group to be detected.
The number threshold may be empirically set, and the specific number is not limited herein, for example, 50, 80 or 100.
Specifically, a number threshold is preset. For each primary number group, if the total number of numbers to be detected contained in the primary number group reaches a preset number threshold, the primary number group may be used as the number group to be detected.
On the basis of the above, if the total number of the numbers to be detected contained in the primary number group does not reach the preset number threshold, combining the primary number group into a primary number group with a smaller number of the numbers to be detected contained in the primary number group adjacent to the primary number group, and judging whether the total number of the numbers to be detected contained in the combined primary number group reaches the preset number threshold.
Specifically, if the total number of numbers to be detected contained in the primary number group does not reach the preset number threshold, it may be determined that the primary number group adjacent to the primary number group contains a smaller number of numbers to be detected. After the determination, the primary number group can be combined into a primary number group with a smaller number to be detected in the primary number group adjacent to the primary number group. After the merging is completed, whether the total number of the numbers to be detected contained in the merged preliminary number group reaches a preset number threshold value or not can be judged.
