Rather, the use of "exemplary" or "for example" is intended to present the concept in a specific manner.

[0036] Before the position information query method provided by the embodiments of the present application is described in detail, the implementation environment and application scenario of the embodiments of the present application are introduced.

[0037] First, the application scenario of the embodiments of the present application is introduced.

[0038] The location information query method of this application embodiment is applied to a scenario where the location information of a device is queried. In related technologies, when a management device queries the location information of a communication device, the management device needs to obtain the identifier of the communication device. Then, based on the identifier of the communication device, the management device determines the location information of the communication device via GPS, thereby completing the query of the location information of the communication device.

[0039] In summary, in the current technical solution, the management device can only determine the location information of the communication device when the GPS positioning service is enabled, which reduces the operability of determining the location information.

[0040] To address the aforementioned problems, this application provides a method for querying location information. The querying device can receive an instruction from a first device to query the location information of a second device. This instruction includes the identifier of the second device. Then, the querying device can obtain the network element device to which the second device is connected based on the identifier of the second device. Next, the querying device can obtain the identifier of the base station to which the second device is connected based on the identifier of the second device and the network element device to which the second device is connected, and determine the location information of the base station to which the second device is connected based on the identifier of the base station. Finally, the querying device sends the location information of the base station to which the second device is connected, as the location information of the second device, to the first device. In other words, the querying device can determine the base station to which the terminal is connected based on the network element device to which the terminal is connected, and determine the location information of the terminal based on the location information of the base station. This improves the operability of determining location information.

[0041] The implementation environment of the embodiments of this application is described below.

[0042] like Figure 1 The diagram illustrates a communication system provided in an embodiment of this application. The communication system includes: a management device (such as server 101), at least one communication device (such as terminal 102, terminal 103), and at least one network element device (such as network element device 104, network element device 105). Server 101 can communicate with terminal 102, terminal 103, network element device 104, and network element device 105 via wired / wireless communication.

[0043] The server 101 can receive a query instruction from the terminal 102 for querying the location information of the terminal 103. The server can send verification information for determining whether to allow positioning of the location information to the terminal 103. The server 101 can also receive confirmation information from the terminal 103 indicating that the positioning of the location information is allowed. The server 101 can also send query credentials to the terminal 102 indicating that the terminal 103 supports querying of the location information. The server 101 can also receive the query credentials from the terminal 102 and manage the query credentials from the terminal 102. The server 101 can also send a query instruction to the network element device 104 for querying the network element device accessed by the terminal 103, and receive information of the network element device 105 from the network element device 104. The server 101 can also send a query instruction to the network element device 105 for querying the base station accessed by the terminal 103, and receive the identity of the base station accessed by the terminal 103 from the network element device 105. The server 101 can determine the location information of the base station accessed by the terminal 103 based on the identity of the base station accessed by the terminal 103, and send the location information of the base station accessed by the terminal 103 to the terminal 102.

[0044] In some embodiments, the server 101 can interact with the terminal 102 (or the terminal 103) through the Hyper Text Transfer Protocol (HTTP) protocol, and the server can interact with the network element device 104 (or the network element device 105) through the mobile markup language (MML) protocol.

[0045] The server (such as the server 101) can be a physical server or a cloud server.

[0046] The terminal (such as the terminal 102 and the terminal 103) can be a device with transceiving function. The terminal can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can be deployed on water surface (such as ships, etc.); can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal includes handheld devices, vehicle-mounted devices, wearable devices or computing devices with wireless communication function. Exemplarily, the terminal can be a mobile phone, a tablet computer or a computer with wireless transceiving function. The terminal device can also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city, a wireless terminal in smart home, etc.

[0047] In some embodiments, the network element device 104 can be a home subscriber server (HSS) network element device. Alternatively, the network element device 104 can be a unified data management (UDM) entity.

[0048] In some embodiments, the network element device 105 can be a mobility management entity (MME). Alternatively, the network element device 105 can be an access and mobility management function (AMF) entity. Alternatively, the network element device 105 can be a visitor location register (VLR).

[0049] After the application scenario and implementation environment of the embodiments of the application are described, the location information query method provided by the embodiments of the application is described in detail below in combination with the implementation environment.

[0050] The methods in the following embodiments can be implemented in the application scenario and implementation environment described above. The embodiments of the application are described in detail below in combination with the accompanying drawings.

[0051] Figure 2 A flowchart of a location information query method provided by the embodiments of the application is shown in FIG. 2. As shown in FIG. 2, the method can include S201-S205. Figure 2

[0052] S201, the server receives a query instruction from a first device.

[0053] The query instruction is used to indicate the location information of a second device, and the query instruction includes a first identifier of the second device.

[0054] In a possible design, the first identifier can be an International Mobile Equipment Identity (IMEI) of the second device.

[0055] In another possible design, the first identifier can be a Mobile Subscriber International ISDN / PSTN number (MSISDN) corresponding to a Subscriber Identification Module (SIM) in the second device. ​

[0056] S202, the server acquires the identifier of the target network element device according to the first identifier.

[0057] The target network element device is a network element device accessed by the second device.

[0058] In a possible implementation, after the server acquires the query instruction from the first device, the server can send the first identifier to the HSS and the UDM entity respectively. The HSS stores identifiers of a plurality of first preset devices and identifiers of a plurality of first preset network element devices, one identifier of a first preset device corresponds to one identifier of a first preset network element device. The UDM entity stores identifiers of a plurality of second preset devices and identifiers of a plurality of second preset network element devices, one identifier of a second preset device corresponds to one identifier of a second preset network element device. Then, the HSS can receive the first identifier from the server. If the HSS determines that there is an identifier of a first preset device in the plurality of identifiers of first preset devices that is the same as the first identifier, the HSS determines the identifier of the target network element device according to the identifier of the first preset device in the plurality of identifiers of first preset devices that is the same as the first identifier, and sends the identifier of the target network element device to the server.

[0059] Similarly, the UDM entity can receive the first identifier from the server. If the UDM entity determines that there is an identifier of a second preset device in the plurality of identifiers of second preset devices that is the same as the first identifier, the UDM entity determines the identifier of the target network element device according to the identifier of the second preset device in the plurality of identifiers of second preset devices that is the same as the first identifier, and sends the identifier of the target network element device to the server.

[0060] In a possible design, if the HSS determines that there is an identifier of a first preset device in the plurality of identifiers of first preset devices that is the same as the first identifier, the target network element device can be any one of an MME and a VLR.

[0061] For example, as shown in Table 1 and Table 2, the correspondence between the identifiers of preset devices stored by the HSS and the identifiers of MMEs and the correspondence between the identifiers of preset devices and VLRs are shown respectively.

[0062] Table 1: Correspondence between identifiers of preset devices and identifiers of MMEs

[0063]

[0064] Table 2: Correspondence between identifiers of preset devices and identifiers of VLRs

[0065]

[0066] In another possible design, if the UDM entity determines that there is a second preset device identifier same as the first identifier in the multiple second preset device identifiers, the target network element device can be an AMF entity.

[0067] For example, as shown in Table 3, a correspondence between the identifiers of the preset devices stored by the UDM entity and the identifiers of the AMF entity is shown.

[0068] Table 3: Correspondence between the identifiers of the preset devices and the identifiers of the UDM entity

[0069]

[0070]

[0071] S203: The server obtains the identifier of the target base station according to the first identifier and the identifier of the target network element device.

[0072] The target base station is a base station accessed by the second device.

[0073] In a possible implementation, the server stores multiple third preset network element device identifiers and multiple preset address information, and one third preset network element device identifier corresponds to one preset address information. After the server obtains the identifier of the target network element device, the server can determine, from the multiple third preset network element device identifiers, a third preset network element device identifier same as the identifier of the target network element device, and determine the target address information according to the third preset network element device identifier same as the identifier of the target network element device in the multiple third preset network element device identifiers, where the target address information is the address information of the target network element device. Then, the server sends the first identifier to the target network element device according to the target address information. After that, the server receives the identifier of the target base station from the target network element device.

[0074] In a possible design, the target network element device stores multiple third preset device identifiers and multiple first preset base station identifiers, and one third preset device identifier corresponds to one first preset base station identifier. After the server sends the first identifier to the target network element device, the target network element device can receive the first identifier from the server. Then, the target network element device can determine, from the multiple third preset device identifiers, a third preset device identifier same as the first identifier, and determine the identifier of the target base station according to the third preset device identifier same as the first identifier in the multiple third preset device identifiers, and send the identifier of the target base station to the server.

[0075] S204: The server determines the location information of the target base station according to the identifier of the target base station.

[0076] In a possible implementation, the server stores a plurality of second preset base station identifiers and a plurality of first preset location information, one second preset base station identifier corresponding to one first preset location information. After the server obtains the identifier of the target base station, the server can determine, from the plurality of second preset base station identifiers, a second preset base station identifier that is the same as the identifier of the target base station, and determine the location information of the target base station according to the second preset base station identifier that is the same as the identifier of the target base station.

[0077] In another possible implementation, the server can be connected with a first database, and the server can interact with the first database. The first database stores a plurality of third preset base station identifiers and a plurality of second preset location information, one third preset base station identifier corresponding to one second preset location information. After the server obtains the identifier of the target base station, the server can determine, based on the first database, a third preset base station identifier that is the same as the identifier of the target base station from the plurality of third preset base station identifiers of the first database, and determine the location information of the target base station according to the third preset base station identifier that is the same as the identifier of the target base station, and obtain the location information of the target base station from the first database.

[0078] It should be noted that the first database can be a 5th generation mobile communication technology (5G) engineering parameter database. Alternatively, the first database can be a 4th generation mobile communication technology (4G) engineering parameter database. Alternatively, the first database can be a 3th generation mobile communication technology (3G) engineering parameter database.

[0079] S205. The server sends the location information of the target base station to the first device.

[0080] That is, the server can take the location information of the target base station as the location information of the second device, and the location information of the target base station can indicate the location of the second device. In addition, the server can take the location information of the target base station as the query result of the first device to the location information of the second device, and send the location information of the target base station to the first device.

[0081] The technical solutions provided by the above embodiments at least have the following beneficial effects: The server can receive a query instruction from the first device, the query instruction being used to indicate querying the location information of the second device, and the query instruction comprising an identifier of the second device. Then, the server can acquire an identifier of a target network element device according to the first identifier, the target network element device being a network element device accessed by the second device. Then, the server can acquire an identifier of a target base station according to the first identifier and the identifier of the target network element device, the target base station being a base station accessed by the second device. Then, the server determines the location information of the target base station according to the identifier of the target base station. Then, the server sends the location information of the target base station to the first device. That is, the server can determine the base station accessed by the terminal according to the network element device accessed by the terminal, and determine the location information of the terminal according to the location information of the base station. In this way, the operability of determining the location information can be improved.

[0082] In some embodiments, as shown in FIG. 3, after S201, the method for querying the location information further comprises S301-S304. Figure 3

[0083] S301, the server sends verification information to the second device.

[0084] The verification information is used to indicate whether to allow positioning the location information.

[0085] In some embodiments, after the server sends the verification information to the second device, the second device can receive the verification information from the server and present the verification information to the user. Then, the second device can receive an operation instruction input by the user to the verification information, and delete the verification information.

[0086] In some embodiments, after the server sends the verification information to the second device, the second device can receive the verification information from the server and present the verification information to the user. Then, the second device can receive an operation instruction input by the user to the verification information, and delete the verification information.

[0087] S302, the server receives the confirmation information from the second device, and sends a first query credential to the first device.

[0088] The first query credential is used to indicate that the location information of the second device is supported to be queried.

[0089] S303, the server receives a second query credential from the first device.

[0090] ​In a possible implementation, the first device can receive a second query credential input by the user, and send the second query credential input by the user to the server. Then, the server can obtain the second query credential from the first device.

[0091] As shown in Figure 4 The first device 400 displays a query page 401, which includes a mobile phone number (i.e., a first identifier) input box 402, a query credential input box 403, a query credential obtaining button 404, and a positioning button 405. In response to an operation (e.g., a click operation) on the query credential obtaining button 404, the first device 400 receives a query credential from the server. For example, the mobile phone number input box 402 can be 12345678901, and the query credential input box 403 can be 853461. In response to an operation (e.g., a click operation) on the positioning button 405, the first device 400 sends a query instruction to the server.

[0092] In a possible design, the first device can receive a second query credential input by the user through a preset application (APP).

[0093] It should be noted that the preset APP is not limited in the embodiments of the present application. For example, the preset APP is an operator business hall APP. For another example, the preset APP is a public number. For another example, the preset APP is a social APP.

[0094] S304, the server determines whether the first query credential and the second query credential are the same.

[0095] In some embodiments, if the server determines that the first query credential and the second query credential are the same, the server performs S202.

[0096] In some embodiments, the query instruction is further used to query state information of the second device. After the server receives the query instruction from the first device, the server can further obtain target state information according to the first identifier and the identifier of the target network element device, and send the target state information to the first device. The target state information is the state information of the second device.

[0097] In a possible implementation, the server can determine target address information according to the identifier of the target network element device, and send the first identifier to the target network element device according to the target address information. Then, the server can receive the target state information from the target network element device.

[0098] In a possible design, the target network element device stores a plurality of third preset device identifiers and a plurality of preset state information, and one third preset device identifier corresponds to one preset state information. After the server sends the first identifier to the target network element device, the target network element device can receive the first identifier from the server. Then, the target network element device can determine, from the plurality of third preset device identifiers, a third preset device identifier that is the same as the first identifier, determine the target state information according to the third preset device identifier that is the same as the first identifier, and send the target state information to the server.

[0099] In a possible design, the state information can include at least one of the following: registration management (RM) state information, an IMEI, connection management (CM) state information, mobility management state information, on-off state information, network type information, a time at which the communication device establishes a connection with the network element device, and a time at which the communication device disconnects from the network element device.

[0100] For example, as shown in Table 4, a correspondence between a preset device identifier and preset state information, and a preset base station identifier stored by an AMF entity is shown. In the table, a registered state is used to indicate that a device is in a powered-on state, and a deregistered state is used to indicate that a device is in a powered-off state.

[0103] For example, as shown in Table 5, a correspondence between a preset device identifier and preset state information, and a preset base station identifier stored by an MME is shown. In the table, IDLE is used to indicate that a device is in an idle state, DEREGISTERED is used to indicate that a device is in a powered-off state, and CONNECTED is used to indicate that a device is in a busy state.

[0104] Table 5: Correspondence between a preset device identifier and preset state information, and a preset base station identifier

[0105]

[0106]

[0107] Exemplarily, as shown in Table 6, a correspondence relationship between the identification of the preset device stored by the VLR and the preset state information, and the identification of the preset base station is shown. Wherein, the ATTACH is used to indicate that the device is in the power-on state, and the DETACH is used to indicate that the device is in the power-off state.

[0108] Table 6: Correspondence relationship between the identification of the preset device and the preset state information, and the identification of the preset base station

[0109]

[0110] It should be noted that if the target network element device is an AMF entity, the network mode information in the target state information is 5G. If the target network element device is an MME, the network mode information in the target state information is 4G. If the target network element device is a VLR, the network mode information in the target state information is 3G.

[0111] In a possible implementation, the server stores a plurality of preset IMEIs and a plurality of preset device models, and one preset IMEI corresponds to one preset device model. If the preset state information corresponding to the third preset device whose identification is the same as the first identification in the plurality of third preset device identifications includes the target IMEI, the server can determine the preset IMEI which is the same as the target IMEI from the plurality of preset IMEIs, and determine the target device model according to the preset IMEI which is the same as the target IMEI in the plurality of preset IMEIs, and generate the target state information.

[0112] In another possible implementation, the server can be connected with a second database, and the server can interact with the second database. The second database stores a plurality of preset IMEIs and a plurality of preset device models, and one preset IMEI corresponds to one preset device model. If the preset state information corresponding to the third preset device whose identification is the same as the first identification in the plurality of third preset device identifications includes the target IMEI, the server can determine the preset IMEI which is the same as the target IMEI from the plurality of preset IMEIs of the second database based on the second database, and determine the target device model according to the preset IMEI which is the same as the target IMEI in the plurality of preset IMEIs, and generate the target state information.

[0113] In some embodiments, after the server determines the location information of the target base station and the target state information, the server can also store the determined location information of the target base station and the target state information, and establish a correspondence relationship between the first identification and the determined location information of the target base station and the target state information.

[0114] Exemplarily, as shown in Table 7, the server stores the correspondence relationship between the first identification and the determined location information of the target base station and the target state information.

[0115] Table 7: Correspondence between the first identifier and the location information of the target base station and the target state information

[0116]

[0117] In a possible implementation, after the server determines the location information of the target base station, the server can further acquire a target time, the target time being a time at which the server determines the location information of the target base station. Then, the server can store the location information of the target base station and the target time, and establish a correspondence between the first identifier and the location information of the target base station and the target time.

[0118] In some other embodiments, a timer is deployed in the server, and the timer stores a preset time. The timer can send a query instruction to the server at the preset time. Then, the server can receive the query instruction from the timer and determine the location information of the target base station at the current time. Then, the server can determine whether the location information of the target base station at the current time is the same as the location information of the target base station at the adjacent preset time. If the server determines that the location information of the target base station at the current time is not the same as the location information of the target base station at the adjacent preset time, the server stores the location information of the target base station at the current time.

[0119] In a possible implementation, if the server determines that the location information of the target base station at the current time is the same as the location information of the target base station at the adjacent preset time, the server deletes the location information of the target base station at the current time.

[0120] The above embodiments will be described below in combination with specific examples. As shown in FIG. 5, the process of the above embodiments includes S501-S505. Figure 5

[0121] S501: The timer initiates a query (i.e., the timer sends a query instruction to the server at a preset time).

[0122] S502: The server queries the location information (i.e., the server receives the query instruction from the timer and determines the location information of the target base station at the current time).

[0123] S503: The server determines whether the queried location information has changed compared with the last location information (i.e., the server determines whether the location information of the target base station at the current time is the same as the location information of the target base station at the adjacent preset time).

[0124] In some embodiments, if the server determines that the queried location information has changed compared with the last location information, S504 is performed.

[0125] ​S504. The server records the time and stores the queried location information (i.e., the server stores the location information of the target base station at the current moment).

[0126] In other embodiments, if the server determines that the queried location information has not changed compared to the previous location information, then S505 is executed.

[0127] S505. The server deletes the queried location information (i.e., the server deletes the location information of the target base station at the current moment).

[0128] In some embodiments, the query instruction is further used to instruct the query of trajectory information of the second device, and the query instruction further includes: a target time period. After the server receives the query instruction from the first device, the server can also determine at least one target location information from historical location information based on the first identifier and the target time period. Then, the server can generate target trajectory information based on the at least one target location information and send the target trajectory information to the first device. The historical location information includes: location information of base stations connected to by the second device at different times; the target location information is the location information within the target time period from the historical location information; the target trajectory information includes at least one target location information and is used to indicate the trajectory of the second device within the target time period.

[0129] In some embodiments, the server may also generate a target map based on the address information of the target base station and send the target map to the first device. The target map includes the address information of the target base station. The first device can then present the target map to the user.

[0130] In one possible design, the server can also generate a target map based on the target base station's address information and the target status information. The target map may also include the target status information.

[0131] For example, such as Figure 6 As shown, the first device 600 displays a query page 601, which includes: network standard information 602, location information 603, device model 604, and map 605. Among them, the network standard information 602 is 4G, the location information 603 is city A, street A, building A, the device model 604 is model A, and the map 605 includes coordinate points 606.

[0132] In some embodiments, the server stores identifiers of multiple fourth preset devices, which are devices that support querying the location information of any device. When the server receives a query instruction from the first device, the server can also obtain the identifier of the first device. If there is an identifier among the multiple fourth preset devices that is the same as the identifier of the first device, the server can skip S301 and directly execute S202.

[0133] In some embodiments, the server may charge the first device a query fee.

[0134] It should be noted that when the server charges the first device for the query, the server can interface with the billing and accounting system to provide package information and query records.
