[0070] Figure 3 The flowchart of the call processing method provided by the embodiments of the present application is shown in the figure. Figure 3 The method includes S101 to S105.

[0071] S101, the electronic device acquires the call state of the first user in the current collection period.

[0072] The call state includes a normal state or an abnormal state.

[0073] Optionally, the time T of the current collection period can be preset in the electronic device by the technician, for example, T can be set as the maximum delay time of the call allowed by the database of the DPI system, and the present application does not limit this.

[0074] Optionally, the electronic device can set the time length T in the timer, and after starting the timer, when the timer reaches the time length T, the call state of the period is acquired.

[0075] In one possible implementation, the electronic device can receive the call state of the current collection period set by the technician.

[0076] In another possible implementation, the electronic device can also determine the call state of the current collection period according to the reference speed between the DPI call generated by the adjacent two times. In this case, Figure 4 Another flowchart of the call processing method provided by the embodiments of the present application is shown in the figure. Figure 4 The above S101 can specifically include S1011 to S1014.

[0077] S1011, the electronic device acquires the current DPI call of the first user collected at present and the historical DPI call collected last time on the current DPI call.

[0078] Optionally, each international mobile subscriber identification number (IMSI) can uniquely identify a user in a mobile network, and the electronic device can obtain the DPI bill of the first user by using the IMSI of the first user. For example, the electronic device can obtain a plurality of DPI bills, and then select all the DPI bills of the first user from the plurality of DPI bills according to the IMSI of the first user. After obtaining all the DPI bills of the first user, the current DPI bill of the first user and the historical DPI bill collected last time are determined.

[0079] In S1012, the electronic device determines a current reference speed corresponding to the current DPI bill according to a bill generation time in the current DPI bill, a current bill point corresponding to the current DPI bill, a bill generation time in the historical DPI bill, and a historical bill point corresponding to the historical DPI bill.

[0080] Optionally, the current reference speed is determined by a quotient of a current reference distance and a current reference time length. The current reference distance is a distance between the current DPI bill point and the historical DPI bill point. The current reference time length is a time length of a difference between the bill generation time in the current DPI bill and the bill generation time in the historical DPI bill.

The current reference distance is a distance between the current DPI bill point and the historical DPI bill point. The current reference time length is a time length of a difference between the bill generation time in the current DPI bill and the bill generation time in the historical DPI bill.

[0084] In S1013, if the current reference speed is greater than a speed threshold, the electronic device sets a bill state of the current collection period to an abnormal state.

[0085] Optionally, the speed threshold can be preset in the electronic device by a technician. For example, the speed threshold can be set to 400 kilometers per hour, which is the fastest speed of a high-speed rail. The present application does not limit this.

[0086] Optionally, if the bill state of the bill is the abnormal state, the electronic device can directly cache the current DPI bill and the DPI bills collected subsequently until the end of the current collection period.

[0087] Optionally, the current reference speed is determined by a quotient of a current reference distance and a current reference time length. The current reference distance is a distance between the current DPI bill point and the historical DPI bill point. The current reference time length is a time length of a difference between the bill generation time in the current DPI bill and the bill generation time in the historical DPI bill.

[0088] S1014, if the current reference speed is less than or equal to the speed threshold, the electronic device sets the state of the call record of the current collection period to the normal state.

[0089] Optionally, if the state of the call record is the normal state, the electronic device can directly send the set of DPI call records to the positioning database.

[0090] S102, if the state of the call record is the abnormal state, the electronic device acquires a set of deep packet inspection (DPI) call records of the first user in the current collection period.

[0091] The set of DPI call records includes one or more DPI call records, and the DPI call record refers to a data service identification result table, which records data generated by the user in the process of online, including user behavior data (such as the time when the call record is generated, the behavior duration), network quality data, terminal state data (such as the access base station cell of the terminal), and traffic detail data, etc. Each DPI call record in the set of DPI call records corresponds to a call record point, and the call record point is used to represent the location of the access base station cell in the corresponding DPI call record.

[0092] Optionally, as described above, if the state of the call record is the abnormal state, the electronic device can directly cache the current DPI call record and the DPI call record collected subsequently, and in this case, the electronic device can specifically acquire the set of DPI call records of the first user in the current collection period from the aforementioned cache.

[0093] S103, the electronic device determines a central call record point in the set of call record points according to the set of DPI call record points.

[0094] The set of call record points is composed of one or more call record points corresponding to the respective DPI call records.

[0095] In one possible implementation, the electronic device can select the call record point with the smallest sum of distances between the call record point and the remaining call record points as the central call record point. In this case, Figure 5 Another flowchart of the call record processing method provided by the embodiments of the present application is shown in FIG. 6. As shown in FIG. 6, the above S103 can specifically include S1031-S1032. Figure 5

[0096] S1031, the electronic device calculates the sum of distances between each call record point in the one or more call record points and the remaining call record points.

[0097] S1032, the electronic device selects the call record point with the smallest sum of distances as the central call record point.

[0098] ​In another possible implementation, the electronic device can first determine a geometric center of one or more of the DPI slip points in the set of DPI slips, and then select as the central slip point the slip point closest to the geometric center.

[0099] Optionally, taking a two-dimensional coordinate system as an example, the electronic device can first calculate the horizontal coordinate and the vertical coordinate of the geometric center, then calculate the distance between each slip point and the geometric center according to the horizontal coordinate and the vertical coordinate of the geometric center, and finally select as the central slip point the slip point with the smallest distance to the geometric center.

[0100] Optionally, the electronic device can calculate the horizontal coordinate of the geometric center according to the following formula (2):

[0101]

[0102] where x is the horizontal coordinate of the geometric center, A ix is the horizontal coordinate of the i th slip point.

[0103] Optionally, the electronic device can calculate the vertical coordinate of the geometric center according to the following formula (3):

[0104]

[0105] where y is the vertical coordinate of the geometric center, A iy is the vertical coordinate of the i th slip point.

[0106] Optionally, after determining the geometric center, the electronic device can calculate the distance between each slip point and the geometric center according to the following formula (4):

[0107]

[0108] where s i is the distance between the i th slip point and the geometric center.

[0109] Optionally, before determining the central slip point, the electronic device can also determine the set of DPI slip points according to the set of DPI slips. In this case, Figure 6 is another flowchart of a slip processing method provided by an embodiment of the present application. As Figure 6 shown, before S1031, the method can further include S201 to S203.

[0110] S201, the electronic device determines the respective access base station cell positions of one or more DPI slips in the set of DPI slips.

[0111] The access base station cell is a wireless area controlled by the base station accessed by the DPI slip.

[0112] S202, the electronic device determines, according to the location of the access base station cell corresponding to each of the one or more DPI call records, a call record point corresponding to each of the one or more DPI call records.

[0113] S203, the electronic device determines, according to the call record points corresponding to the one or more DPI call records, a set of DPI call record points.

[0114] S104, the electronic device determines, according to the time of generation of each of the one or more DPI call records, the call record point corresponding to each of the one or more DPI call records, the time of generation of the central call record in the central call record point corresponding to the DPI call record, and the central call record point, a first reference speed corresponding to each of the one or more DPI call records.

[0115] The first reference speed is determined by the quotient of the first reference distance and the first reference time length. The first reference distance is the distance between the call record point corresponding to each of the one or more DPI call records and the central call record point. The first reference time length is the time length of the difference between the time of generation of each of the one or more DPI call records and the time of generation of the central call record.

[0116] Optionally, the electronic device can calculate the first reference time length according to the following formula (5):

[0117] T i = |T ni -T0|i = 0, 1, 2, 3, … n Formula (5)

[0118] Wherein, T i is the first reference time length of the i-th DPI call record, T ni is the time of generation of the i-th DPI call record, and T0 is the time of generation of the central call record point.

[0119] Optionally, when the location of the call record point is latitude and longitude, the electronic device can calculate the first reference speed corresponding to the DPI call record according to the latitude and longitude corresponding to the DPI call record and the central call record point and the first reference time length, and according to the first reference time length and the first reference distance. In this case, Figure 7 is another flowchart of the call record processing method provided by the embodiments of the present application. As shown in Figure 7 S104 can specifically include S1041 to S1044.

[0120] S1041, the electronic device determines the difference in longitude and the difference in latitude between the call record point corresponding to each of the one or more DPI call records and the central call record point.

[0121] S1042, the electronic device determines the first reference distance according to a difference in longitude, a difference in latitude, and a preset conversion relationship between the respective call record points of the one or more DPI call records and the central call record point.

[0122] The conversion relationship can include: 1 degree = 111 kilometers, 1 minute = 1.85 kilometers, and 1 second = 31 meters.

[0123] Alternatively, the electronic device can obtain the difference in longitude and the difference in latitude between the respective call record points of the one or more DPI call records and the central call record point, multiply the degrees, minutes, and seconds corresponding to the difference in longitude and the difference in latitude by the lengths corresponding to the degrees, minutes, and seconds in the conversion relationship, respectively, to obtain distances corresponding to the difference in longitude and the difference in latitude, and use the Pythagorean theorem to calculate the first reference distance as the hypotenuse, using the distances corresponding to the difference in longitude and the difference in latitude as the two right-angle sides of the plane right triangle.

[0124] For example, taking the unit of distance as kilometers, 1 degree = 111 kilometers, 1 minute = 1.85 kilometers, and 1 second = 0.031 kilometers, the degrees, minutes, and seconds of the latitude of the i-th call record point are A i °B i ′C i ″, and the degrees, minutes, and seconds of the central call record point are A0°B0′C0″. The electronic device can calculate the distance in latitude between the i-th call record point and the central call record point according to the following formula (6):

[0125] D i = 111 * |A i °-A0°| + 1.85 * |B i ′-B0′| + 0.031 * |C i ″-C0″| Formula (6)

[0126] where D i is the distance in latitude between the i-th call record point and the central call record point.

[0127] The degrees, minutes, and seconds of the longitude of the i-th call record point are H i °E i ′F i ″, and the degrees, minutes, and seconds of the longitude of the central call record point are H0°E0′F0″. The electronic device can calculate the distance in longitude between the i-th call record point and the central call record point according to the following formula (7):

[0128] L i = 111 * |H i °-H0°| + 1.85 * |E i ′-E0′| + 0.031 * |F i ″-F0″| Formula (7)

[0129] where Li is the distance between the i th bill point and the center bill point in longitude.

[0130] The electronic device can calculate the first reference distance of the i th bill point according to the following formula (8) :

[0131]

[0132] wherein S i is the first reference distance between the i th bill point and the center bill point.

[0133] S1043, the electronic device determines the first reference time length according to the respective bill generation time of each of the one or more DPI bills and the center bill generation time of the center bill point corresponding to the DPI bill.

[0134] S1044, the electronic device determines the first reference speed according to the quotient of the first reference distance and the first reference time length.

[0135] Alternatively, the electronic device can calculate the first reference speed of the i th DPI bill according to the following formula (9) :

[0136]

[0137] wherein V i is the first reference speed of the i th DPI bill, T i is the first reference time length of the i th DPI bill.

[0138] S105, if there is an abnormal bill corresponding to the first reference speed greater than the speed threshold, the electronic device deletes the position of the access base station cell in the abnormal bill.

[0139] The bill processing method provided by the embodiments of the present application can obtain a set of DPI bills in an abnormal state, determine a center bill point in the set of DPI bill points, the center bill point can represent the center of the activity range of the first user in the current collection period, take the center bill point as a reference, calculate the first reference speed corresponding to the DPI bill according to the distance between the bill point corresponding to each DPI bill and the center bill point and the time length difference between the bill generation time of each DPI bill and the center bill generation time, if the first reference speed corresponding to a certain DPI bill is too large and exceeds the preset speed threshold, it indicates that the DPI bill is too far away from the center of the activity range and deviates from the reasonable activity range of the first user in the current collection period, so that the DPI bill can be confirmed as an abnormal bill, and the position of the access base station cell in the abnormal bill is deleted, thereby reducing the DPI bills with incorrect access base station cell positions.

[0140] Based on the understanding of the above embodiments, Figure 8This is another flowchart illustrating the call detail record (CDR) processing method provided in this application. Figure 8 As shown, the call detail record (CDR) processing method includes: streaming DPI CDRs according to IMSI, grouping DPI CDRs with the same IMSI into one category, determining whether the period in which the DPI CDR file is located is in an abnormal state. If the period is in an abnormal state, the DPI CDR is cached. If the period is not in an abnormal state, it is determined whether the speed corresponding to the DPI CDR file and the historical DPI CDR file exceeds a speed threshold. If it exceeds the speed threshold, the period is placed in an abnormal state. If it does not exceed the speed threshold, the DPI CDR is sent to the location database. The specific implementation can be referred to the above embodiment, and will not be repeated here.

[0141] Based on the understanding of the above embodiments, Figure 9 This is another flowchart illustrating the call detail record (CDR) processing method provided in this application.
