[0002] In communication networks, the location information of user terminals is a basic information in network operation and maintenance. In many scenarios, the operation and maintenance of communication networks are based on location information. For example, when a user complains about call establishment failure or sudden call drop after call establishment, the operator needs to know the location information of the user when the call establishment fails or the call drops, so as to quickly handle the fault and improve network performance; for another example, the operator needs to conduct active business analysis based on the location information of the user terminal and present it geographically, so as to obtain which areas or cells are busy in order to carry out targeted expansion and optimization.

[0068] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0069] In the description below, words such as “first” and “second” are only used for the purpose of distinguishing the description and should not be understood as indicating or implying relative importance or order.

[0070] First, the application scenario of the present disclosure is described. The present disclosure can be applied to the acquisition of location information of user terminals in a communication network, especially the acquisition of location information of user terminals in a VoLTE (Voice over LTE, voice based on LTE network) network. In the related art, the location information of the user terminal is usually acquired based on the network interface data at the start of the user call, and recorded in the call detail record (CDR) of the user terminal. The inventor found that: in actual applications, due to the complexity of the network interface, the location information cannot be obtained at the start of the user call, or the obtained location information is inaccurate, resulting in incomplete or inaccurate location information in the call detail record.

[0071] In order to solve the above problems, the present disclosure provides a method, device, storage medium and electronic device for obtaining location information. The method obtains the target user identification of the target user terminal and the first location information of the target user terminal at the current time, determines the target call detail record of the target user terminal according to the target user identification and the current time, and updates the second location information using the first location information according to the current time and the call start time. In this way, when the second location information cannot be obtained at the start time of the user call, or the obtained second location information is inaccurate, the second location information can be updated by this method, so that accurate and complete second location information is recorded in the call detail record.

[0072] It should be noted that the network interface data capable of obtaining user location information in the VoLTE network includes at least one of the following interface data: Mw interface data, Gm interface data, Rx interface data, S1 interface data, Gx interface data, Sh interface data. The above interfaces belong to the standard interfaces in the 3GPP (3rd Generation Partnership Project) protocol, and the specific description in the 3GPP protocol can be referred to, and this disclosure will not repeat them.

[0073] The preset interface priority includes: the interface data is sorted from high to low in the following order: Mw interface data priority>Rx interface data priority>S1 interface data priority>Gm interface data priority>Gx interface data priority>Sh interface data.

[0074] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0075] Figure 1 A method for obtaining location information provided by an embodiment of the present disclosure is as follows: Figure 1 As shown, the method includes:

[0076] S101: Acquire a target user identifier of a target user terminal.

[0077] The target user identifier may be the MSISDN (Mobile Subscriber International ISDN number) or IMSI (International Mobile Subscriber Identification number) of the target user terminal.

[0078] This step can be triggered according to the network interface data collected in the communication network, or according to an externally input instruction. Therefore, the target user identifier of the target user terminal can be obtained from the network interface data, for example, the MSISDN of the target user terminal can be obtained from the GM interface data or the GX interface data as the target user identifier; it can also be obtained according to an externally input instruction, for example, if the operator needs to query the location information of a certain target user terminal, the target user identifier can be obtained from the instruction input by the user; for another example, when the call detail record of the target user terminal needs to be queried, the method for obtaining the location information provided in this embodiment can be executed by obtaining the target user identifier of the call detail record to be queried.

[0079] S102: Acquire first location information of the target user terminal at the current moment.

[0080] In this step, there are multiple ways to obtain the first location information. For example, a location request message may be sent to the target user terminal, and the target user terminal may report the first location information at the current moment; the first location information of the target user terminal at the current moment may be obtained through the collected network interface data; or the historical location information of the target user terminal may be obtained from a historical location database.

[0081] S103: Determine a target call detail record from at least one call detail record according to the target user identifier and the current time.

[0082] The target call detail record is used to record the call information of the target call of the target user terminal, and the call information includes the call start time of the target call and the second location information of the target user terminal at the call start time.

[0083] It should be noted that the at least one call detail record mentioned above may be one or more call detail records stored in a local disk or server, each call detail record may include a user ID and a call start time, representing a call or a data service call process of a user terminal corresponding to the user ID, and the same user ID may have multiple call detail records. In addition, the second location information in the call detail record may be a valid value or an invalid value. Generally, at the start time of the call, if the location information of the target user terminal is not obtained, the second location information is an invalid value, which may be a preset invalid value or an invalid string, such as a value of 0 or a string NULL; if the location information of the target user terminal is obtained at the start time of the call, the location information of the target user terminal is used as the above-mentioned second location information.

[0084] In this step, according to the target user ID and the current time, the target user ID closest to the current time can be found from at least one call detail record, and determined as the target call detail record. The target call detail record that meets the following three conditions can be found and determined from the at least one call detail record: 1) the user ID is the same as the target user ID; 2) the call start time is less than or equal to the current time; 3) the absolute value of the time difference between the call start time and the current time is the smallest. In this way, the call detail record with the smallest absolute value of the time difference between the call start time and the current time can be obtained, so as to update the location information in the call detail record.

[0085] Furthermore, on the basis of the above three conditions, the target call detail record can also be required to meet any one of the following two conditions: the call end time in the target call detail record is later than the current time, or the absolute value of the time difference between the call start time and the current time is less than or equal to a preset search time threshold, which can be any time from 0 to 30 minutes.

[0086] S104: Update the second location information using the first location information according to the current time and the call start time.

[0087] In this step, when the current time is greater than or equal to the call start time, the first location information can be used as the second location information, that is, the second location information in the target call detail record can be replaced by the first location information.

[0088] The first location information can also be used as the second location information when the absolute value of the time difference between the current time and the call start time is less than or equal to the first time threshold. The first time threshold can be less than the above-mentioned preset search time threshold. For example, the first time threshold can be any time from 0 to 20 minutes.

[0089] By adopting the above method, the target user identification of the target user terminal is obtained, the first location information of the target user terminal at the current time is obtained, the target call detailed record of the target user terminal is determined according to the target user identification and the current time, and the second location information is updated using the first location information according to the current time and the call start time. In this way, when the second location information cannot be obtained at the start time of the user call, or the obtained second location information is incomplete or inaccurate, the second location information can be updated by this method, thereby obtaining accurate and complete second location information.

[0090] It should be noted that the location information described in the present disclosure may include longitude and latitude information, such as longitude and latitude reported by the terminal, or longitude and latitude information of the terminal obtained in the communication network according to the signaling of the terminal; on the other hand, the location information described in the present disclosure may also include network location information and / or administrative area information, wherein the network location information may include: one or more of the cell identifier, base station identifier and location area identifier, and the administrative area information may include one or more of the country, province, city, district, county and township. That is, the first location information in the above embodiment may include the first network location information and / or the first administrative area information; the above second location information may include the second network location information and / or the second administrative area information.

[0091] Optionally, the first location information may be obtained in step S102 in one or both of the following two ways:

[0092] Method 102-1: Acquire the first location information of the target user terminal at the current moment through network interface data.

[0093] The network interface data of the target user terminal during the call process can be obtained, and the first location information of the target user terminal at the current moment can be obtained according to the network interface data. The network interface data can be one or more of Mw interface data, Gm interface data, Rx interface data, S1 interface data, Gx interface data and Sh interface data.

[0094] By way of example, the first location information may include a cell identifier and a location area identifier. The cell identifier may be the ECI (E-UTRAN Cell Identifier) ​​in the 3GPP protocol. The cell identifier and the location area identifier may be collected from the Invite request message of the Gm interface data, and the first location information may be obtained based on the cell identifier and the location area identifier. The specific acquisition method may refer to the field definition in the 3GPP protocol.

[0095] Mode 102-2: according to the target user identifier and the current time, obtain the historical location information of the target user terminal from at least one historical location information, and use the historical location information as the first location information.

[0096] The historical location information is location information of the target user terminal at a historical moment obtained according to network interface data at the historical moment, and the historical moment is earlier than the current moment.

[0097] The at least one historical location information may be temporary location information stored in a memory or a database, which records the user identification, historical location information and the historical moment of obtaining the historical location information of each user terminal.

[0098] In this way, when the first location information cannot be obtained through the network interface data, the historical location information of the target user terminal can be obtained as the first location information, which can increase the completeness of the user location information acquisition.

[0099] Furthermore, it is also possible to determine whether the absolute value of the time difference between the historical moment and the call start moment is less than or equal to the second time threshold. If it is determined that the absolute value of the time difference between the historical moment and the call start moment is less than or equal to the second time threshold, the historical location information is used as the first location information. In this way, it is considered that the historical location information within the second time threshold of the call start moment is accurate and can be used as the first location information, which can further increase the accuracy of obtaining the user location information.

[0100] In addition, the above historical location information can also be updated in time. When the first location information of the target user terminal at the current moment is obtained through the network interface data, the historical location information of the target user terminal can be updated according to the target user identifier and the current moment.

[0101] For example, after obtaining the first location information, it can be confirmed based on the target user identifier whether the target user terminal has historical location information stored in the memory or database. If the historical location information has been stored, the historical location information is updated to the first location information, and the historical moment when the historical location information was obtained is recorded as the current moment. If the target user terminal does not store historical location information in the memory or database, a new historical location information can be stored, with the first location information of the target user identifier as the historical location information and the current moment as the historical moment.

[0102] In this way, it can be ensured that the historical location information is the latest location information of the target user terminal, and when the historical location information is needed, more accurate location information can be obtained.

[0103] In some other embodiments of the present disclosure, the above-mentioned location information may include network location information, that is, the first location information includes the first network location information, and the second location information includes the second network location information. In the case where the above-mentioned step S102 is to obtain the first location information of the target user terminal at the current moment through the network interface data, the above-mentioned step S104 may be implemented in the following two ways to update the second location information using the first location information according to the current moment and the call start time:

[0104] Method 104-1: When the absolute value of the time difference between the current time and the call start time is less than or equal to the first time threshold, the first network location information of the target user terminal at the current time is used as the second network location information, and the current time is used as the current update time of the second network location information.

[0105] Among them, the first time threshold can be a preset time for confirming that the user location information is credible, which is related to the user's movement speed. In communication networks where the user movement speed is faster, such as highways and high-speed railways, the first time threshold can be set to a shorter time, for example, it can be any time from 0 to 2 minutes; and in communication networks where the user movement speed is slower, such as urban residential areas and business districts, the first time threshold can be set to a longer time, for example, it can be any time from 0 to 20 minutes.

[0106] In this way, when the absolute value of the time difference between the current time and the call start time is less than or equal to the first time threshold, the first network location information is credible and can be used as the second network location information to obtain accurate location information of the user terminal.

[0107] Method 104-2: When the absolute value of the time difference between the current time and the call start time is greater than the above-mentioned first time threshold, and the absolute value of the time difference between the current time and the call start time is less than the absolute value of the time difference between the last update time of the second network location information and the call start time, the first network location information is used as the second network location information, and the current time is used as the current update time of the second network location information.

[0108] In this way, when the conditions in the above-mentioned method 104-2 are met, the first network location information is closer to the call start time than the second network location information, so relatively accurate location information of the user terminal can be obtained.

[0109] It should be noted that, in the above manner, if the first network location information is consistent with the second network location information, the second network location information may continue to remain unchanged.

[0110] In some other embodiments of the present disclosure, the above-mentioned location information may also include network location information, that is, the first location information includes the first network location information, the second location information includes the second network location information, and the target call detail record may further include the priority of the second network location information, so that:

[0111] In the case where the first location information of the target user terminal at the current moment is obtained through the network interface data in the above step S102, the priority of the first network location information can also be obtained according to the network interface data.

[0112] Among them, the priority of the first network location information can be used to characterize the accuracy of the location information in the network interface data. The higher the priority, the higher the corresponding accuracy. By way of example, the network interface data may include: Mw interface data, Gm interface data, Rx interface data, S1 interface data, Gx interface data, Sh interface data, etc. The priority of the first network location information obtained from the above network interface data can be sorted from high to low in the following order: Mw interface data priority>Rx interface data priority>S1 interface data priority>Gm interface data priority>Gx interface data priority>Sh interface data. Of course, the priority of the above network interface data is used for example, and can also be sorted according to other priorities.

[0113] Then, the method of using the first location information to update the second location information in the above step S104 may be: when a first preset condition is met, the first network location information is used as the second network location information, the priority of the first network location information is used as the priority of the second network location information, and the current time is used as the current update time of the second network location information, wherein the first preset condition includes any one of the following conditions:

[0114] Condition 1: the absolute value of the time difference between the current time and the call start time is less than or equal to the first time threshold, and the priority of the first network location information is higher than the priority of the second network location information;

[0115] Condition 2: the absolute value of the time difference between the current time and the call start time is less than or equal to the first time threshold, and the priority of the first network location information is equal to the priority of the second network location information, and the current time is earlier than the last update time of the second network location;

[0116] Condition 3: The absolute value of the time difference between the current time and the call start time is greater than the first time threshold, and the absolute value of the time difference between the current time and the call start time is less than the absolute value of the time difference between the last update time of the second network location information and the call start time.

[0117] It should be noted that, when the above-mentioned first preset condition is met, it can be confirmed that the first network location information is more accurate than the second network location information. Therefore, the first network location information can be used as the second network location information to record more accurate location information in the call detail record.

[0118] In some other embodiments of the present disclosure, the above-mentioned location information may include network location information and administrative district information, that is, the first location information includes first network location information and first administrative district information, and the second location information includes second network location information and second administrative district information. In this way, when the network interface data includes the user network location information, the first location information of the target user terminal at the current moment can be obtained in the following manner:

[0119] The first network location information of the target user terminal at the current moment is obtained through the network interface data; and the administrative district information corresponding to the first network location information is obtained according to the network administrative district correspondence as the first administrative district information of the target user terminal at the current moment.

[0120] The network administrative region correspondence relationship includes administrative region information corresponding to different network location information. For example, the network location information may include TAC, the administrative region information may include a city, and the network administrative region correspondence relationship may be a correspondence relationship as shown in Table 1 below.

[0121] Network location information Administrative district information TAC100 A city TAC101 A city TAC102 City B

[0122] Table 1

[0123] As shown in Table 1: TAC100 and TAC101 correspond to city A, and TAC102 corresponds to city B. In this way, if the acquired TAC is 101, then according to the network administrative region correspondence, it can be obtained that the administrative region information corresponding to the TAC is city A, and city A can be used as the first administrative region information of the target user terminal at the current moment.

[0124] Then, according to the current time and the call start time, the second network location information in the target call detail record may be updated using the first network location information, and the second administrative region information in the target call detail record may be updated using the first administrative region information.

[0125] For example, when the current time is greater than or equal to the call start time, the first location information can be used as the second location information, and the first administrative district information can be used as the second administrative district information; or when the absolute value of the time difference between the current time and the call start time is less than or equal to the first time threshold, the first location information can be used as the second location information, and the first administrative district information can be used as the second administrative district information.

[0126] In this way, through the above method, the network location information of the user terminal can be obtained, and the corresponding administrative area information can be obtained based on the network location information of the user terminal. The second network location information and the second administrative area information of the target user terminal are also recorded in the call detail record, and the operation and maintenance of the communication network.

[0127] Optionally, when the network interface data does not include user network location information, but the network interface data includes the roaming number, area code or domain name of the target user terminal, the roaming number, area code or domain name can be obtained through the network interface data; the first administrative district information can be obtained based on the roaming number, area code or domain name; and the second administrative district information in the target call detail record can be updated using the first administrative district information based on the source time of the interface data and the call start time.

[0128] Among them, the CSRN (CS Domain Routing Number) field in the UDA (User Data Answer) message of the Sh interface data can be obtained as the roaming number. For example, if the CSRN is 86139XXXXXX, the roaming number is determined to be 86139XXXXXX. According to the roaming number, the city to which the number belongs can be determined, and the city can be used as the first administrative region information.

[0129] In addition, the area code or domain name can also be obtained from the SBC-DOMAIN field of the INVITE message of the Mw port. For example, the SBC-DOMAIN field contained in the INVITE message is sbc03.020.001.gd.gz.chinamobile.com, where 020 is the area code and gd.gz is the domain name. Accordingly, according to the area code 020, it can be determined that the corresponding city is M, and according to the domain name gd.gz, it can also be determined that the corresponding city is M. It should be noted that the format of the sbc-domain can be preset, and the area code and domain name therein, as well as the administrative district information corresponding to the area code and domain name, can be determined according to the preset format.

[0130] In this way, when the network interface data does not contain the user's network location information, the first administrative district information can be obtained through the roaming number, area code or domain name, and the first administrative district information can be used as the second administrative district information in the target call detail record, thus ensuring the integrity of the location information record.

[0131] In addition, the above-mentioned updating of the second administrative region information in the target call detail record by using the first administrative region information according to the current time and the call start time can be implemented in the following manner:

[0132] If the absolute value of the time difference between the current time and the call start time is less than or equal to the second time threshold, the first administrative region information is used as the second administrative region information, and the current time is used as the current update time of the second administrative region information.

[0133] The second time threshold may be equal to or different from the first time threshold. The second deletion threshold may be a preset time for confirming that the acquired first administrative district information is credible, for example, any time from 0 to 60 minutes. In this way, when the absolute value of the time difference between the current time and the call start time is less than or equal to the second time threshold, the first administrative district information is credible, and the first administrative district information may be used as the second administrative district information to record the accurate second administrative district information of the target user terminal in the target call detail record.

[0134] Furthermore, the second administrative district information may be updated using the first administrative district information according to the last update time of the second administrative district information and the call start time. The updating method may be the following two methods:

[0135] If the absolute value of the time difference between the last update time of the second administrative district information and the call start time is greater than the third time threshold, the first administrative district information is used as the second administrative district information, and the current time is used as the current update time of the second administrative district information;

[0136] If the absolute value of the time difference between the last update time of the second administrative district information and the call start time is greater than the third time threshold, and the absolute value of the time difference between the current time and the call start time is less than the absolute value of the time difference between the last update time of the second administrative district information and the call start time, the first administrative district information is used as the second administrative district information, and the current time is used as the current update time of the second administrative district information.

[0137] Among them, the third time threshold can be any time from 1 minute to 1440 minutes. When the absolute value of the time difference between the last update time of the second administrative district information and the call start time is greater than the third time threshold, the second administrative district information is no longer credible. Therefore, the first administrative district information is used to update the second administrative district information to record relatively accurate administrative district information of the user terminal.
