[0002] Voice over WiFi (VoWiFi) is a voice calling technology based on the IP Multimedia Subsystem (IMS), similar to Voice over Long-Term Evolution (VoLTE). It allows smartphone users to make voice or video calls over WiFi when connected to a WiFi network, without relying on the mobile operator's cellular network.

[0003] Currently, operators can support user devices to access the 4G / 5G core network through non-3GPP access methods, using the IMS network to provide users with services such as voice calls and SMS, which is called VoWiFi service. Existing VoWiFi user location technologies, which estimate the user's location during a VoWiFi call based on the time and location of the user's access to the cellular network before and after the call, have significant errors. Furthermore, methods that determine location information using the user's IP address and port number cannot respond to location requests from external positioning systems. Summary of the Invention

[0051] The following is a detailed description of a call detail record (CDR) data recording method provided in this application, with reference to the accompanying drawings.

[0052] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0053] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0054] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0055] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0056] To facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish the same or similar items with essentially the same function and effect. Those skilled in the art can understand that the terms "first" and "second" are not intended to limit the quantity or execution order.

[0057] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0058] According to the background technology description, the current mobile user positioning technology in the core network queries the AMF / MME for the location information of the cell accessed by the user equipment through the GMLC / LCS network element. However, in VoWiFi service, the UE does not access the core network through the AMF / MME network element, nor does it access cell information through the base station. Therefore, the current mobile user positioning technology is not entirely suitable for the positioning of VoWiFi users.

[0059] VoWiFi user location technologies are mainly divided into two categories: One category considers that after a user connects to WiFi, their location is not too far from the WiFi network they are connected to. Therefore, the user's location is determined by the installation address of the WiFi network they are connected to. This method uses network devices such as evolved packet data gateways or traceability gateways within the network to determine the WiFi network the user is connected to through the user's IP address and port number, and provides the user's WiFi access location information to other core network elements. However, there is no complete method or process for providing VoWiFi user location information for location requests initiated by external positioning systems to core network devices. The other category estimates the user's current location by using the cell information and time difference between the user's two previous WiFi accesses to the cellular network, or by using the cell information and time of the user's previous and subsequent WiFi accesses to the cellular network. This positioning method has a large margin of error.

[0060] To address the aforementioned technical issues, this application provides a VoWiFi user location method, which involves: determining the target area where the target user is currently located; sending a first request message to the network management system of the target area, the first request message being used to request a query of the broadband information accessed by the target user; receiving a first response message sent by the network management system of the target area, the first response message being used to indicate the broadband information accessed by the target user; and determining the location information of the target user based on the broadband information accessed by the target user, thereby enabling accurate location of VoWiFi users.

[0061] The VoWiFi user location method provided in this application will be described in detail below with reference to the accompanying drawings.

[0062] Figure 1This is a schematic diagram of a communication network architecture provided in an embodiment of this application. Figure 1 As shown, the communication network includes: User Equipment (UE), wireless routers, Evolved Packet Data Gateway (ePDG), Unified Data Management (UDM) network element, 3GPP AAA server, converged network element SMF+PGW-C, Policy Control Function (PCF) network element, Policy and Charging Rules Function (PCRF) network element, Location-Based Services (LBS) platform, Session Border Controller (SBC), and IP Multimedia Subsystem (IMS) enhanced network management.

[0063] User equipment (UE) is an important concept in mobile communications. UE can be a mobile phone, smart terminal, multimedia device, streaming media device, etc. In this application, it refers to a device that supports VoWiFi service.

[0064] A wireless router is primarily responsible for converting wired network signals into wireless signals, enabling devices that support Wi-Fi technology (such as computers, mobile phones, tablets, etc.) to access the internet wirelessly. In this application, the wireless router connects VoWiFi user devices, whose location information needs to be determined, to the wireless network.

[0065] The Evolved Packet Data Gateway (ePDG) is a key component in mobile communication networks. Its main function is to ensure secure access for UEs transmitting data from untrusted non-3GPP access networks (such as home Wi-Fi, enterprise Wi-Fi, public Wi-Fi, etc.) to the Evolved Packet Core (EPC) network.

[0066] The Unified Data Management (UDM) network element is responsible for user data management, service network element registration management, interface services, user authentication, and identity decryption. In this application, the UDM receives a third request message from the location service platform requesting to query the SMF information currently accessed by the target user, and sends a third response message to the location service platform indicating the SMF information currently accessed by the target user. This enables the location service platform to determine the target area where the target user is currently located based on the SMF information currently accessed by the target user, and then obtain the broadband information accessed by the target user from the network management system of the target area.

[0067] The 3GPP AAA server provides users with authentication, authorization, and accounting (AAA) functions and supports non-3GPP access.

[0068] The converged network element SMF+PGW-C is a fusion of the Session Management Function (SMF) network element and the Packet Data Network Gateway Control Plane (PGW-C). The SMF is responsible for controlling how users access the network and how data is transmitted in the network, while also providing management functions such as session creation, modification, and release. The PGW-C is responsible for signaling interaction with the User Equipment (UE) and managing the user's data session state.

[0069] The Policy Control Function (PCF) network element / Policy and Charging Rules Function (PCRF) network element is mainly responsible for providing policy-based decision-making mechanisms and flow-based charging functions.

[0070] Location-based services (LBS) platforms utilize mobile devices to obtain users' geographic locations and provide users with relevant information and services based on this location information.

[0071] It should be noted that, Figure 1 In the communication network shown, an LBS platform is used as an example for illustration. In other embodiments, the LBS platform can be replaced by a location service platform in 4G or 5G. This application does not limit this embodiment.

[0072] A Session Border Controller (SBC) is located at the edge of a voice network and can view all incoming and outgoing traffic (control plane and data plane), protecting the voice system from malicious use.

[0073] The IP Multimedia Subsystem (IMS) enhanced network management system improves network operation and maintenance efficiency and ensures network security by enhancing control capabilities, strengthening automated operation and maintenance, enhancing security, and improving scalability and flexibility. In this application, the IMS enhanced network management system is responsible for acquiring signaling messages from the message interface and analyzing these messages to determine and save user identification information, user access broadband information, user VoWiFi registration status information, etc. Upon receiving a first request message from the location service platform requesting a query of the target user's access broadband information, it returns the user's access broadband information or a query failure code to the location service platform based on the user's online status. In other embodiments, the network management system involved in this application can be other network management systems capable of saving user VoWiFi registration status information and home broadband information. For example, the IMS enhanced network management system can be replaced with a 5G core network enhanced network management system, and the corresponding communication network architecture is as follows: Figure 2 As shown.

[0074] It is understood that the embodiments of this application do not limit the functional network elements included in the mobile communication system. In some embodiments, the mobile communication system may also add new functional network elements or enhance the capabilities of existing network elements to provide new capabilities internally and externally. The newly added functional network elements or enhanced existing network elements may also operate based on the methods in this application.

[0075] It should be noted that the application scenarios of the embodiments of this disclosure are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0076] The VoWiFi user location method provided in the embodiments of this disclosure will be described in detail below.

[0077] Figure 3 The flowchart of a VoWiFi user positioning method provided in this application embodiment is applied to a location service platform. For example, the location service platform involved in this application can be a location-based services (LBS) platform or a 4G / 5G base station positioning platform.

[0078] like Figure 3 As shown, the method includes the following steps:

[0079] S101. Determine the target region where the target user is currently located.

[0080] The target user is a VoWiFi user. For example, the target user is a VoWiFi user whose location information is to be determined.

[0081] In some embodiments, the target region can be the province where the user is currently located.

[0082] For example, the specific implementation of step S101 can be found in steps S1011-S1014, which will not be repeated here.

[0083] S102. Send the first request message to the network management system of the target area.

[0084] The first request message is used to request the broadband information accessed by the target user.

[0085] In some embodiments, the first request message includes a user identifier of the target user. For example, the user identifier may be a Mobile Station International Subscriber Directory Number (MSISDN), such as a user's mobile phone number.

[0086] In some embodiments, prior to step S102, the method further includes: determining the identifier of the network management system of the target region based on the target region and the third mapping relationship.

[0087] The third mapping relationship is the mapping relationship between the region and the identifier of the network management system.

[0088] Based on this, step S102 can be specifically implemented as follows: based on the identifier of the network management system in the target area, send a first request message to the network management system in the target area.

[0089] S103, Receive the first response message sent by the network management system of the target area.

[0090] The first response message is used to indicate the broadband information accessed by the target user.

[0091] For example, the first response message may include at least one of the following: identification information of the broadband accessed by the target user, account information of the broadband accessed by the target user, and installation address of the broadband accessed by the target user.

[0092] S104. Determine the location information of the target user based on the broadband information accessed by the target user.

[0093] For example, location information can be information representing a user's geographical location, such as latitude and longitude.

[0094] In some embodiments, step S104 may specifically be implemented as: determining the location information of the target user based on the broadband information accessed by the target user and the fourth mapping relationship.

[0095] The fourth mapping relationship is the mapping relationship between broadband information and location information. For example, the fourth mapping relationship can be the mapping relationship between broadband information and latitude and longitude.

[0096] In some embodiments, such as Figure 4 As shown, before step S101, the method further includes step S100:

[0097] S100: Receive a second request message sent by an external system.

[0098] The second request message is used to request the location information of the target user.

[0099] In some embodiments, the second request information sent by the external system includes the target user's user identifier. After receiving the second request message, the location service platform obtains and saves the target user's user identifier.

[0100] Following step S104, the method further includes step S105:

[0101] S105. Send a second response message to an external system.

[0102] The second response message is used to indicate the location information of the target user.

[0103] It is understood that the VoWiFi user location method provided in this application can respond to query requests from external systems of the core network for the location of VoWiFi users.

[0104] In some embodiments, such as Figure 5 As shown, step S101 can be specifically implemented as the following steps S1011-S1014:

[0105] S1011. Determine the target UDM to which the target user belongs.

[0106] In some embodiments, step S1011 may specifically be implemented as: determining the UDM to which the target user belongs based on the target user's user identifier and the first mapping relationship.

[0107] The first mapping relationship is the mapping relationship between the user identifier and the UDM.

[0108] S1012, Send a third request message to the target UDM.

[0109] The third request message is used to request a query of the target user's currently accessed SMF information.

[0110] In some embodiments, the third request message includes the user identifier of the target user.

[0111] S1013. Receive the third response message sent by the target UDM.

[0112] The third response message is used to indicate the SMF information currently accessed by the target user.

[0113] S1014. Based on the SMF information currently accessed by the target user, determine the target region where the target user is currently located.

[0114] In some embodiments, step S1014 can be specifically implemented as: determining the target region where the target user is currently located based on the SMF information currently accessed by the target user and the second mapping relationship.

[0115] The second mapping relationship is the mapping relationship between SMF information and regions.

[0116] In some embodiments, the first mapping relationship, the second mapping relationship, the third mapping relationship and the fourth mapping relationship described above are provided to the location service platform by the network service operator.

[0117] It is understood that this application obtains the broadband information accessed by the target user by sending a request to the network management system of the target user's current location, and determines the target user's location information based on the broadband information, thereby accurately obtaining the location of the user accessing VoWiFi calls.

[0118] Figure 6 A flowchart of another VoWiFi user location method provided in this application embodiment, applied to UDM, the method includes the following steps:

[0119] S201, Receive a third request message sent by the location service platform.

[0120] The third request message is used to request a query of the target user's currently accessed SMF information.

[0121] S202, Send a third response message to the location service platform.

[0122] The third response message is used to indicate the SMF information currently accessed by the target user.

[0123] It should be understood that sending a response message to the location service platform enables the location service platform to determine the target area where the target user is currently located based on the SMF information currently accessed by the target user, and then obtain the broadband information accessed by the target user from the network management system of the target area.

[0124] Among them, the broadband information accessed by the target user is used to determine the target user's location information.

[0125] Figure 7 A flowchart of another VoWiFi user location method provided in this application embodiment, applied to a network management system, the method includes the following steps:

[0126] S301, Receive the first request message sent by the location service platform.

[0127] The first request message is used to request the broadband information accessed by the target user.

[0128] S302. Send the first response message to the location service platform.

[0129] The first response message is used to indicate the broadband information accessed by the target user; the broadband information accessed by the target user is used to determine the location information of the target user.

[0130] In some embodiments, the above method further includes: obtaining signaling messages from the message interface; analyzing the signaling messages to determine and save at least one of the following information: user identification information, user access broadband information, and user VoWiFi registration status information.

[0131] In some embodiments, the network management system of the target area stores at least one of the following information: user identification information, user access broadband information, and user VoWiFi registration status information.

[0132] Among them, the user's VoWiFi registration status information is used to determine the user's VoWiFi online status and whether to return the user's access broadband information to the user.

[0133] Optionally, step S302 can be specifically implemented as follows:

[0134] S3021. Based on the VoWiFi registration status information corresponding to the target user, determine whether the target user is in a VoWiFi online state.

[0135] S3022. When the target user is online via VoWiFi, send a first response message to the location service platform.

[0136] In some embodiments, if the target user is offline via VoWiFi, a query failure error code is sent to the location service platform.

[0137] It should be understood that the network management system involved in this application needs to be able to save the user's VoWiFi registration status information and the user's broadband access information. For example, the network management system can be an IMS enhanced network management system or a 5GC enhanced network management system.

After obtaining the broadband information, it is converted into the user's location information and finally the user's location information is returned to the external system. This method can accurately locate VoWiFi users and solves the problem in the prior art that it cannot respond to location requests from external systems of the core network.

[0141] The second request message contains the target user's user identifier.

[0142] In some embodiments, the user identifier of the target user may be the user's mobile phone number.

[0143] S2. The location service platform determines the UDM to which the target user belongs based on the target user's user identifier and the first mapping relationship.

[0145] S3. The location service platform sends a third request message to the target UDM. The third request message is used to request the query of the target user's currently accessed SMF information.

[0146] In some embodiments, the third request message includes the user identifier of the target user.

[0147] S4. UDM returns a third response message to the location service platform. The third response message is used to indicate the SMF information currently accessed by the target user.

[0148] S5. The location service platform determines the target region where the target user is currently located based on the SMF information currently accessed by the target user and the second mapping relationship.

[0149] The second mapping relationship is the mapping relationship between SMF information and regions.

[0150] S6. The location service platform determines the identifier of the network management system in the target area based on the target area and the third mapping relationship.

[0151] The third mapping relationship is the mapping relationship between the region and the identifier of the network management system.

[0152] S7. The location service platform sends a first request message to the network management system of the target area. The first request message is used to request the query of the broadband information accessed by the target user.

[0153] In some embodiments, the first request message includes the user identifier of the target user.

[0154] S8. The network management system returns a first response message to the location service platform. The first response message is used to indicate the broadband information accessed by the target user.

[0155] S9. The location service platform determines the location information of the target user based on the broadband information accessed by the target user and the fourth mapping relationship.

[0156] The fourth mapping relationship is the mapping relationship between broadband information and location information. For example, the fourth mapping relationship can be the mapping relationship between broadband information and latitude and longitude.
