Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a terminal location tracing method, device, electronic device, and storage medium. Background Art

[0002] With the rapid development of 5G technology, VoWiFi has become an important means for operators to provide high-quality voice services. Tracing the broadband location of VoWiFi users is crucial for operators, as it allows them to accurately locate users' actual locations when using VoWiFi services.

[0003] In the related art, during the VoWiFi user broadband location tracing process, the fixed-line AAA / tracing system transmits the user's broadband location information to the tracing gateway based on the actual geographic location mapped to the user's broadband access IP address. However, the accuracy of the actual geographic location mapped to the user's broadband access IP address depends on the operator's management of the registered address of the optical modem device. If the registered address is incorrect, the VoWiFi user's broadband tracing will be inaccurate. This sole reliance on broadband location tracing cannot ensure the accuracy and reliability of the user's location.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0059] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0060] Figure 1 A flow chart of a terminal location tracing method according to an embodiment of the present disclosure is shown as follows: Figure 1 As shown, the terminal location tracing method provided in the embodiment of the present disclosure includes the following steps:

[0061] S102, in response to receiving a location query request sent by the voice wireless local area network system, simultaneously obtaining the terminal broadband location information from the broadband network tracing system and the terminal cellular location information from the mobile core network tracing system.

[0062] It should be noted that the information carried in the above-mentioned location query request may include: broadband access Internet Protocol address, International Mobile Subscriber Identity / mobile phone number, request to obtain terminal broadband location information, and request to obtain terminal cellular location information. The above-mentioned terminal broadband location information includes the actual geographical location mapped to the broadband access Internet Protocol address. The above-mentioned terminal cellular location information includes the cell identifier Cell ID, tracking area identifier TA ID, current location retrieved CurrentLocationRetrieved or location information age.

[0063] S104: Determine whether the terminal broadband location information and the terminal cellular location information meet preset conditions.

[0064] It should be noted that the above preset conditions may include a first preset condition and a second preset condition.

[0065] For example, the above S104 may include the following steps: determining whether the broadband location information of the terminal meets a first preset condition; and determining whether the cellular location information of the terminal meets a second preset condition.

[0066] S106, in response to the terminal broadband location information and the terminal cellular location information meeting the preset conditions, the terminal broadband location information and the terminal cellular location information are simultaneously transmitted to the voice wireless LAN system, so that the voice wireless LAN system can trace the terminal location according to the terminal broadband location information and the terminal cellular location information.

[0067] The present disclosure combines the terminal cellular location and broadband location for tracing, which can make up for the disadvantages of single broadband tracing and improve the accuracy and reliability of terminal location tracing.

[0068] In one embodiment of the present disclosure, the location query request includes a broadband access IP address, an international mobile subscriber identity code / mobile phone number, such as Figure 2 As shown, the terminal location tracing method provided in the embodiment of the present disclosure can determine whether the terminal broadband location information meets the first preset condition through the following steps, and can successfully obtain the terminal broadband location information:

[0069] S202, determining whether the Internet Protocol address cached by the broadband is the same as the Internet Protocol address of the broadband access based on the international mobile subscriber identity code / mobile phone number, and whether the cached broadband location information of the terminal meets the preset time limit of the first cache;

[0070] S204: If the Internet Protocol addresses are the same and meet the preset validity period of the first cache, the terminal broadband location information meets the first preset condition.

[0071] In one embodiment of the present disclosure, Figure 3 As shown, the terminal location tracing method provided in the embodiment of the present disclosure can determine whether the terminal cellular location information meets the second preset condition through the following steps, and can successfully obtain the terminal cellular location information:

[0072] S302, determining whether the terminal cellular location information includes the retrieved parameters of the current location;

[0073] S304: If the terminal cellular location information includes a current location retrieved parameter, the terminal cellular location information satisfies a second preset condition.

[0074] For example, if the terminal cellular location information carries the parameter "Current Location Retrieved", it means that the current location of the terminal has been retrieved, and the Cell ID and TA ID are immediate results, valid and credible (equivalent to the above terminal cellular location information meeting the second preset condition).

[0075] In one embodiment of the present disclosure, Figure 4 As shown, the terminal location tracing method provided in the embodiment of the present disclosure further includes the following steps to determine whether the terminal cellular location information meets the second preset condition, which can ensure the accuracy and validity of the obtained terminal cellular location information:

[0076] S402, if the terminal cellular location information includes location information timeliness, determining whether the location information timeliness meets a preset timeliness of the second buffer;

[0077] S404: If the timeliness of the location information meets the preset timeliness of the second buffer, the terminal cellular location information meets the second preset condition.

[0078] For example, if the terminal cellular location information carries the parameter "Age of location information", it means that the Cell ID and TA ID at this time are the result of the terminal's most recent interaction with the core network. At this time, the validity of the terminal cellular location information must be judged based on the "Age of location information". For example, if the "Age of location information" is less than or equal to a certain time limit (equivalent to the preset time limit of the above-mentioned second cache), for example, 5 minutes, then the Cell ID and TA ID at this time are considered valid and reliable (equivalent to the above-mentioned terminal cellular location information meeting the second preset condition).

[0079] In one embodiment of the present disclosure, Figure 5 As shown, the terminal location tracing method provided in the embodiment of the present disclosure further includes the following steps before determining whether the terminal cellular location information meets the second preset condition, which can provide basic data for determining whether the terminal cellular location information is valid:

[0080] S502, determining whether the cell identifier and tracking area identifier of the cellular location information are successfully obtained;

[0081] S504: If yes, determine whether the terminal cellular location information meets the second preset condition.

[0082] Based on the same inventive concept, the present disclosure also provides a terminal location tracing device, as described in the following embodiments. Since the principle of solving the problem in the device embodiment is similar to that in the above method embodiment, the implementation of the device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.

[0083] Figure 6 A schematic diagram of a terminal location tracing device according to an embodiment of the present disclosure is shown. Figure 6As shown, the device includes: an information acquisition module 61, an information judgment module 62, and an information transmission module 63.

[0084] The information acquisition module 61 is configured to, in response to receiving a location query request sent by the voice wireless local area network system, simultaneously acquire the terminal broadband location information from the broadband network tracing system and the terminal cellular location information from the mobile core network tracing system;

[0085] An information determination module 62 is configured to determine whether the terminal broadband location information and the terminal cellular location information meet preset conditions;

[0086] The information transmission module 63 is used to transmit the terminal broadband location information and the terminal cellular location information to the voice wireless local area network system at the same time in response to the terminal broadband location information and the terminal cellular location information meeting the preset conditions, so that the voice wireless local area network system can trace the terminal location according to the terminal broadband location information and the terminal cellular location information.

[0087] In an example of the present disclosure, the information determination module 62 is specifically configured to determine whether the terminal broadband location information satisfies a first preset condition; and determine whether the terminal cellular location information satisfies a second preset condition.

[0088] In one example of the present disclosure, the location query request in the terminal location tracing device includes a broadband access Internet Protocol address and an international mobile user identification code / mobile phone number; the information judgment module 62 also judges whether the Internet Protocol address of the broadband cache is the same as the Internet Protocol address of the broadband access based on the international mobile user identification code / mobile phone number, and whether the cache of the terminal broadband location information meets the preset time limit of the first cache; if the Internet Protocol addresses are the same and meet the preset time limit of the first cache, then the terminal broadband location information meets the first preset condition.

[0089] In one example of the present disclosure, the above-mentioned information judgment module 62 is also used to judge whether the terminal cellular location information includes the current location retrieved parameter; if the terminal cellular location information includes the current location retrieved parameter, the terminal cellular location information meets the second preset condition.

[0090] In one example of the present disclosure, the above-mentioned information judgment module 62 is also used to, if the terminal cellular location information includes location information timeliness, determine whether the location information timeliness meets the preset timeliness of the second cache; if the location information timeliness meets the preset timeliness of the second cache, then the terminal cellular location information meets the second preset condition.

[0091] In one example of the present disclosure, the information determination module 62 is further configured to determine whether the cell identifier and tracking area identifier of the cellular location information are successfully acquired; if so, to determine whether the terminal cellular location information satisfies a second preset condition.

[0092] It should be noted that the information acquisition module 61, information determination module 62, and information transmission module 63 described above correspond to S102 to S106 in the method embodiment. The examples and application scenarios implemented by these modules and corresponding steps are the same, but are not limited to the contents disclosed in the method embodiment described above. It should be noted that the above modules, as part of the apparatus, can be executed in a computer system, such as a set of computer-executable instructions.

[0093] Figure 7 A schematic diagram showing the structure of a terminal location tracing system in an embodiment of the present disclosure is shown. Figure 7 As shown, the system architecture includes a voice wireless LAN system 701, a tracing gateway 702, a broadband network system 703 and a mobile core network tracing system 704;

[0094] Among them, the tracing gateway 702 includes an interface module 7021, a judgment module 7022, a cache database 7023 and a cache timer 7024.

[0095] The interface module is used to connect with relevant network elements, such as voice wireless LAN system elements, broadband network tracing system elements, mobile core network tracing system elements, etc.

[0096] After the tracing gateway receives the location query request sent by the voice wireless LAN system network element through the interface module, it first determines whether there is cached data through the judgment module. If there is no cached data, the tracing gateway initiates the process of obtaining the terminal location information; if there is cached data, it again determines whether the broadband access IP address has changed. If it has changed, the tracing gateway re-initiates the process of obtaining the terminal broadband and cellular location information. If there is no change: it then determines whether the terminal broadband and cellular location information cache timer has timed out. If it has timed out, the tracing gateway re-initiates the process of obtaining the terminal broadband and cellular location information. If it has not timed out, the tracing gateway returns the terminal broadband and cellular location information cached in the cache database to the voice wireless LAN system.

[0097] The voice wireless LAN system is a non-3GPP access system, including but not limited to 4G network elements ePDG, 5G network elements AMF, 6G related network elements, etc.

[0098] The broadband network traceability system is a broadband network, including but not limited to home broadband, government and enterprise broadband, satellite broadband and other trusted and untrusted networks. Its traceability system includes but is not limited to fixed-line AAA, CRM platform, etc.

[0099] The mobile core network traceability system is the mobile core network, including but not limited to the 4G / 5G core network and the 6G core network. Its traceability system includes but is not limited to the 4G / 5G core network network elements HSS+UDM, 6G related network elements, signaling monitoring system, positioning platform GMLC / LRF, satellite positioning platform, etc.

[0100] For example, the judgment logic includes but is not limited to the following situations:

[0101] The first case, such as Figure 8 As shown in the figure: When the terminal broadband location information and cellular location information cache timer settings are the same, the tracing gateway judgment includes the following steps:

[0102] S801, the traceability gateway receives a terminal location query request;

[0103] S802, determine whether there is cached data in the terminal location query request, if so, execute S803, if not, execute S806;

[0104] S803, determine whether the broadband IP address in the cached data has changed, if not, execute S804, if so, execute S806;

[0105] S804, determine whether the timer has timed out. If the timer has not timed out, execute S805. If the timer has timed out, execute S806.

[0106] S805, returning the terminal broadband location information and the terminal cellular location information in the cache database to the voice wireless LAN system, and ending the process;

[0107] S806: The tracing gateway initiates a request to obtain the terminal broadband location information and the terminal cellular location information.

[0108] It should be noted that the above-mentioned cache timer includes a terminal broadband location information cache timer (first timer) and a cellular location information cache timer (second timer), and the terminal location information is only valid within the specified time of the cache timer.

[0109] Second case: If Figure 9 As shown in the figure: When the cache timers of the terminal broadband location information (execution of the first timer) and the cellular location information (execution of the second timer) are set to different times, the tracing gateway judgment includes the following steps:

[0110] S901: The traceability gateway receives a terminal location query request;

[0111] S902, determine whether there is broadband IP address cache data in the terminal location query request, if so, execute S903, if not, execute S908;

[0112] S903, check whether the broadband IP address in the cache data has changed, if not, execute S904, if so, execute S908;

[0113] S904, determine whether the first timer has timed out, if not, execute S905, if so, execute S908;

[0114] S905, determine whether there is cellular location information cache data in the terminal location query request, if so, execute S906, if not, execute S909;

[0115] S906, determine whether the second timer has timed out, if not, execute S907, if yes, execute S909;

[0116] S907, returning the terminal broadband location information and the terminal cellular location information in the cache database to the voice wireless LAN system, and ending the process;

[0117] S908, the tracing gateway initiates a request to obtain the terminal broadband location information and the terminal cellular location information;

[0118] S909, the tracing gateway initiates a request to obtain the terminal's cellular location information.

[0119] In addition, after receiving the terminal traceability query response from the traceability system via the interface module, the traceability gateway must determine the terminal's location information. This determination includes the following three conditions: whether the terminal's broadband location information was successfully acquired; whether the terminal's cellular location information was successfully acquired; and whether the terminal's cellular location information is valid. If these three conditions are met, the traceability gateway returns a success flag, the terminal's broadband location information, and the cellular location information to the voice wireless LAN system, caches the broadband location information and the cellular location information, and resets the first and second timers. If any of these conditions are not met, the traceability gateway returns an indication denying the terminal access to the voice wireless LAN system.

[0120] It should be noted that the above-mentioned cache database is designed to avoid the signaling load caused by the frequent interaction between the tracing gateway and the tracing system when the user frequently switches between the voice wireless LAN network and the cellular network. It enables the tracing gateway to have the function of caching information including but not limited to user numbers, broadband location information and cellular location information.

[0121] In a specific example, Figure 10 As shown in the figure, in the scenario where there is no cached data in the traceability gateway, the operation of the terminal location traceability system includes the following steps:

[0122] S1001: The VoWiFi system sends a location query request to the tracing gateway. The request message carries information including but not limited to the broadband access IP address, port number, IMSI / MSISDN, etc., requesting the terminal broadband and cellular location information.

[0123] S1002: The tracing gateway determines that there is no corresponding cached data based on the IMSI / MSISDN, and then simultaneously obtains the terminal broadband location information from the broadband network tracing system and the terminal cellular location information from the mobile core network tracing system:

[0124] S10021: The tracing gateway sends a broadband tracing query request to the broadband network tracing system to obtain the terminal broadband location information (the actual geographical location of the terminal mapped to the broadband access IP address);

[0125] S10022: The traceability gateway sends a cellular traceability query request to the mobile core network traceability system to obtain the terminal cellular location information (Cell ID, TA ID, Current Location Retrieved or Age of location information).

[0126] S1003: The broadband network tracing system returns the terminal broadband location information to the tracing gateway, and the mobile core network tracing system returns the terminal cellular location information to the tracing gateway.

[0127] S10031: The broadband network traceability system returns a broadband traceability query response to the traceability gateway, carrying the terminal broadband location information (the actual geographical location of the terminal mapped to the broadband access IP address);

[0128] S10032: The mobile core network traceability system returns a cellular traceability query response to the traceability gateway, carrying the terminal cellular location information (Cell ID, TA ID, Current Location Retrieved or Age of location information).

[0129] It should be noted that the cellular traceability query response does not carry both the "Current Location Retrieved" and "Age of location information" parameters; only one of them is carried. If the "Current Location Retrieved" parameter is carried, it means that the terminal's current location has been retrieved, and the Cell ID and TA ID are immediate, valid, and reliable. If the "Age of location information" parameter is carried, it means that the Cell ID and TAID at this time are the result of the terminal's most recent interaction with the core network. In this case, the validity of the terminal's cellular location information must be determined based on the Age of location information.

[0130] S1004: After receiving the broadband traceability query response and the cellular traceability query response, the traceability gateway performs the following three judgments on the terminal location information:

[0131] Whether the terminal broadband location information is successfully obtained;

[0132] Whether the cellular location information Cell ID and TA ID are successfully obtained;

[0133] Determine whether the validity of the cellular location information meets any of the following conditions: If the cellular traceability query response carries the parameter "Current Location Retrieved", the Cell ID and TA ID at this time are considered valid and reliable; if the cellular traceability query response carries the parameter "Age of location information", the parameter "Age of locationinformation" is less than or equal to a certain time limit, for example, 5 minutes, then the Cell ID and TA ID at this time are considered valid and reliable.

[0134] S1005. If the above three judgments are met at the same time, the tracing gateway returns a success mark, the terminal broadband location information and the cellular location information to the VoWiFi system, caches the broadband location information and the cellular location information, and resets the cache timers T1 (equivalent to the above-mentioned first timer) and T2 (equivalent to the above-mentioned second timer); if any one of the judgments is not met, the tracing gateway returns an indication of rejecting the terminal's access to VoWiFi.

[0135] In a specific example, Figure 11As shown in the figure, the tracing gateway caches the terminal broadband and cellular location information. The VoWiFi terminal broadband access IP address is the same as the cached data. The broadband location information cache T1 has not timed out, but the cellular location information cache timer T2 has timed out. The tracing gateway only needs to obtain the terminal cellular location information from the tracing system. At this time, the terminal location tracing system includes the following steps when running:

[0136] S1101: The VoWiFi system sends a location query request to the tracing gateway. The request message carries information including but not limited to the broadband access IP address, port number, IMSI / MSISDN, etc., requesting to obtain the terminal broadband and cellular location information;

[0137] S1102, the tracing gateway determines based on the IMSI / MSISDN that the broadband IP address cached by the user is the same as the broadband access IP address at this time, and the broadband location information cache timer T1 has not timed out, but the cellular location information cache timer T2 has timed out, then obtains the cellular location information (including but not limited to Cell ID and TA ID) and CurrentLocation Retrieved indication or Age of location information from the mobile core network tracing system.

[0138] S1103, the mobile core network traceability system returns a cellular traceability query response to the traceability gateway, carrying the terminal cellular location information (Cell ID and TA ID), Current Location Retrieved or Age of location information.

[0139] S1104: After receiving the cellular traceability query response, the tracing gateway performs the following two judgments on the terminal's cellular location information:

[0140] Determine whether the cellular location information Cell ID and TA ID are successfully obtained;

[0141] The validity of cellular location information is determined by any of the following: if the cellular traceability query response carries the parameter "Current Location Retrieved", the Cell ID and TA ID at this time are considered valid and credible; if the cellular traceability query response carries the parameter "Age of location information", and the Age of location information is less than or equal to a certain time limit, such as 3 minutes, the Cell ID and TA ID at this time are considered valid and credible.

[0142] S1105, if both judgments are passed, the tracing gateway returns a success mark, the cached terminal broadband location information and the newly acquired cellular location information to the VoWiFi system, caches the newly acquired cellular location information, and resets the cache timers T1 and T2; if any of the judgments is not met, the tracing gateway returns an indication of denying the terminal access to VoWiFi.
