Detailed Implementation
[0020] The embodiments of this application will now be described in more detail with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0021] To address the technical issues of current technologies that rely on base station deployment density and signal models to determine terminal location information, resulting in high positioning latency during video calls, and requiring the terminal to actively report data, which prevents real-time triggering during video calls and compromises the security of location information, this embodiment provides a location determination method, such as... Figure 1 As shown, the method includes: Step 101: In response to the target terminal device being in 5G video communication state, receive the SMS location instruction sent by the server.
[0022] In this embodiment of the application, the target terminal device can be a terminal device in 5G video communication state. Specifically, the terminal device (End-User Device / Terminal Device) can be a hardware device that is directly operated by the user for accessing the network, running applications, and obtaining services. For example, the terminal device can include, but is not limited to, mobile phones, tablets, desktop computers, vehicle-mounted systems, etc.
[0023] In some examples, the 5G video communication status can refer to the state of a terminal device conducting video communication in a 5G network environment; for example, the video communication status can include, but is not limited to, the state of a terminal device during video calls, video conferences, live interactive sessions, etc., in a 5G network environment.
[0024] For example, if user 1 and user 2 respectively connect to a video call in a 5G network environment through terminal device 1 and terminal device 2, it can be determined that terminal device 1 and terminal device 2 can be the target terminal devices in this application embodiment, and terminal device 1 and terminal device 2 are in the 5G video communication state in this application embodiment.
[0025] As an alternative approach, if user 1 and user 3 connect to a video conference in a 5G network environment through terminal device 1 and terminal device 3 respectively, then terminal device 1 and terminal device 3 can be determined to be the target terminal devices in this application embodiment, and terminal device 1 and terminal device 3 are in the 5G video communication state in this application embodiment.
[0026] As an alternative approach, if user 2 and user 3 conduct live interaction in a 5G network environment through terminal device 2 and terminal device 3 respectively, then terminal device 2 and terminal device 3 can be determined to be the target terminal devices in this application embodiment, and terminal device 2 and terminal device 3 are in the 5G video communication state in this application embodiment.
[0027] In this embodiment, in a 5G video communication system, the server-side can undertake core functions such as media processing, session control, resource scheduling, intelligent enhancement, and network collaboration. Compared with 4G or traditional video communication architectures, the server-side in a 5G environment needs to deeply coordinate with 5G network capabilities (such as network slicing, MEC, and QoS assurance) to achieve an ultra-high-definition, low-latency, highly reliable, and intelligent video communication experience. It should be noted that the server-side in this embodiment can also be a server, a cloud server, a remote server, etc.
[0028] In this embodiment, the SMS location command can be a command sent by the server to the terminal device to trigger the acquisition of location information. Specifically, the SMS location command in this embodiment can include a unique identifier (such as a UUID) and an encryption token. For example, the video call server (i.e., the server in this embodiment) can send an SMS command containing a unique identifier (such as a UUID) and an encryption token to the client terminal (i.e., the target terminal device in this embodiment). The SMS content format can be: GET_LOCATION: <uuid> : <timestamp> : <signature>.
[0029] In this embodiment, a unique identifier is a standard mechanism for generating globally unique IDs in a distributed system without centralized coordination. Its core objective is to ensure that IDs generated by any device at any time are virtually unique, without relying on a central registry.
[0030] In some examples, the encrypted information can specifically be a cryptographic token, a digital credential generated based on cryptographic principles for authentication, authorization, or data protection. It is not a simple string, but a secure object constructed using a key, algorithm, and payload, possessing characteristics such as anti-forgery, anti-tampering, and verifiability. It should be noted that the use of cryptographic tokens in this application embodiment ensures the security of the location determination process.
[0031] For example, if user 1 and user 2 respectively connect to a video call in a 5G network environment through terminal device 1 and terminal device 2, it can be determined that terminal device 1 and terminal device 2 can be the target terminal devices in this application embodiment. If terminal device 1 and terminal device 2 are in the 5G video communication state in this application embodiment, a text message location command can be sent to terminal device 1 and terminal device 2 to obtain the location information of terminal device 1 and terminal device 2.
[0032] As an alternative approach, if user 1 and user 3 connect to a video conference in a 5G network environment through terminal device 1 and terminal device 3 respectively, then terminal device 1 and terminal device 3 can be determined to be the target terminal devices in this application embodiment. If terminal device 1 and terminal device 3 are in the 5G video communication state in this application embodiment, then a text message location command can be sent to terminal device 1 and terminal device 3 to obtain the location information of terminal device 1 and terminal device 3.
[0033] Step 102: Obtain the location information of the target terminal device based on the SMS location command.
[0034] In this embodiment of the application, the location information can be the location information of the target terminal device, such as, but not limited to, latitude and longitude coordinates, data-format location information, etc.
[0035] As an alternative approach, if User 1 and User 2 have successfully connected to a video call in a 5G network environment via Terminal Device 1 and Terminal Device 2 respectively, then Terminal Device 1 and Terminal Device 2 can be identified as target terminal devices in this embodiment. Since Terminal Device 1 and Terminal Device 2 are in a 5G video communication state in this embodiment, a text message location command can be sent to Terminal Device 1 and Terminal Device 2 to obtain their location information. Subsequently, after receiving the text message location command, Terminal Device 1 and Terminal Device 2 can obtain their own location information.
[0036] As an alternative approach, if User 1 and User 3 connect to a video conference in a 5G network environment through Terminal Device 1 and Terminal Device 3 respectively, then Terminal Device 1 and Terminal Device 3 can be determined to be the target terminal devices in this application embodiment. If Terminal Device 1 and Terminal Device 3 are in the 5G video communication state in this application embodiment, then a text message location command can be sent to Terminal Device 1 and Terminal Device 3 to obtain their location information; and then after receiving the text message location command, Terminal Device 1 and Terminal Device 3 can obtain their own location information respectively.
[0037] Optionally, when executing "obtaining the location information of the target terminal device based on the SMS location command", the following method may be used, but is not limited thereto: the method includes: verifying the signature validity based on the identification information in the SMS location command; if the signature validity verification is successful, generating a first acquisition request for location information, the first acquisition request being used to request the user to authorize the acquisition of the location information from the target location service; and in response to the user's confirmation authorization command, acquiring the location information through the target location service.
[0038] In this embodiment, signature validation is a process that uses cryptographic methods to verify whether the digital signature of a piece of data is authentic, complete, and has not been tampered with. It is a core mechanism for ensuring data trustworthiness in scenarios such as communication security, identity authentication, software distribution, and electronic transactions.
[0039] For example, in this embodiment of the application, the target terminal device can perform signature validity verification based on the identification information in the SMS location instruction, and if the signature validity verification is successful, generate a request for the user to authorize the acquisition of the location information from the target location service.
[0040] In some examples, the first acquisition request may be a request for the user to authorize the acquisition of the location information from the target location service, which may be location service software, location service program, etc. in the target terminal device.
[0041] For example, when the target terminal device is terminal device 1, the target location service can be the location service software or location service program in terminal device 1. After the terminal device 1 passes the signature validity verification, it can generate a request for the user to authorize the acquisition of location information from the location service software or location service program in terminal device 1 (i.e., the first acquisition request in this application). When the user authorizes based on the first acquisition request, terminal device 1 can acquire its own location information from the location service software or location service program.
[0042] For example, when the target terminal device is terminal device 2, the target location service can be the location service software or location service program in terminal device 2. After the terminal device 2 passes the signature validity verification, it can generate a request for the user to authorize the acquisition of location information from the location service software or location service program in terminal device 2 (i.e., the first acquisition request in this application). When the user authorizes based on the first acquisition request, terminal device 2 can acquire its own location information from the location service software or location service program.
[0043] As an optional approach, the client terminal (i.e., the target terminal device in this application embodiment) can parse the instructions in the SMS message and trigger the positioning process after verifying the validity of the signature. Specifically, the client terminal (i.e., the target terminal device in this application embodiment) can call the system positioning service, such as the Fused LocationProvider, to request the user's authorization to obtain the real-time location. Among these options, GPS or Beidou high-precision mode can be selected first to obtain the location information of the client terminal (i.e., the target terminal device in this application embodiment).
[0044] Optionally, after executing "generating a first request to obtain location information if the signature validity verification passes", the following method may be used, but is not limited to: in response to the user's denial of authorization instruction, generating a second request to obtain location information, wherein the first request is used to request the access network device connected to the target terminal device to determine the location information; and receiving the location information sent by the access network device.
[0045] In some examples, the second acquisition request may be a request to the access network device to send location information. For example, when the target terminal device is terminal device 1, after the signature validity verification of terminal device 1 is passed, a request can be generated to request the user to authorize the acquisition of location information from the location service software or location service program in terminal device 1 (i.e., the first acquisition request in this application). If the user refuses to authorize the acquisition of location information from the location service software or location service program, then terminal device 1 can generate a request to request the access network device to send location information (i.e., the second acquisition request in this application embodiment) and receive its own location information sent by the access network device.
[0046] For example, when the target terminal device is terminal device 2, the target location service can be the location service software or location service program in terminal device 2. After the terminal device 2 passes the signature validity verification, it can generate a request for the user to authorize the acquisition of location information from the location service software or location service program in terminal device 2 (i.e., the first acquisition request in this application). If the user refuses to authorize the acquisition of location information from the location service software or location service program, then terminal device 2 can generate a request for the access network device to send location information (i.e., the second acquisition request in this application embodiment) and receive its own location information sent by the access network device.
[0047] As an alternative, if the user refuses authorization, the client terminal (i.e., the target terminal device in this application embodiment) can fall back to base station triangulation or WiFi fingerprint positioning as alternative solutions to obtain its own location information.
[0048] Step 103: Encrypt the location information according to the encryption format indicated by the SMS location instruction.
[0049] Optionally, when performing the "encryption of location information according to the encryption format indicated by the SMS location instruction", the following methods may be used, but are not limited to: determining the timestamp information corresponding to the location information; and encrypting the location information according to the encryption format indicated by the SMS location instruction based on the timestamp information and the identification information.
[0050] In this application embodiment, a timestamp can be a number or string representation that records the specific time point when an event occurred. In computer systems, network communications, security protocols, log tracing, and distributed systems, timestamps are a fundamental element for realizing key functions such as timing control, state synchronization, replay attack prevention, and audit tracing.
[0051] In this embodiment, the timestamp information corresponding to the location information can be determined, and then the location information can be encrypted according to the target encryption format based on the timestamp information and the identification information to obtain the encrypted location information in this application.
[0052] For example, when the target terminal device is terminal device 1, if terminal device 1 obtains its own location information 1, it can determine the timestamp information 1 of the location information 1, and encrypt the location information 1 according to the target encryption format based on the timestamp information 1 and the identification information 1 of terminal device 1 to obtain the encrypted location information in this application embodiment.
[0053] For example, when the target terminal device is terminal device 2, if terminal device 2 obtains its own location information 2, it can determine the timestamp information 1 of the location information 2, and encrypt the location information 2 according to the target encryption format based on the timestamp information 2 and the identification information 2 of terminal device 2 to obtain the encrypted location information in this application embodiment.
[0054] As an optional approach, the client terminal (i.e., the target terminal device in this application embodiment) can encrypt the obtained latitude and longitude coordinates (i.e., the location information in this application embodiment) through the HTTPS protocol to obtain the target encrypted information in this application embodiment, and send the target encrypted information to the video call server (i.e., the server in this application embodiment). The encryption algorithm adopts a standard encryption algorithm, such as SM4 encryption algorithm or AES-256 encryption algorithm, etc.
[0055] Step 104: Send the encrypted location information to the server.
[0056] Location information is used by the server to update the location of the target terminal device.
[0057] As an optional approach, the server can decrypt the encrypted location information upon receipt. After decryption, the server can update the customer's location marker in the call interface and synchronize it to the backend management system. It should be noted that the location data is only used for this call and is stored in the server's memory rather than in a persistent database.
[0058] Compared with existing technologies, this embodiment receives a location command sent by the server in response to the target terminal device being in 5G video communication mode, and obtains the location information of the target terminal device based on the location command. This allows the embodiment to initiate the location information acquisition operation in response to the SMS command, reducing the location acquisition delay during video calls and improving the timeliness of location acquisition. This embodiment can also encrypt the location information before sending it by using an encryption format in the SMS location command, improving the security of information transmission and making the location information acquisition process more reliable.
[0059] To illustrate the server-side processing, this embodiment also provides a location determination method, such as... Figure 2 As shown, it includes: Step 201: In response to the target terminal device being in 5G video communication state, obtain the identification information and encryption information corresponding to the terminal device.
[0060] In this embodiment, the executing entity can be a server, specifically a video call server. In a 5G video communication system, the server-side can undertake core functions such as media processing, session control, resource scheduling, intelligent enhancement, and network collaboration. Compared to 4G or traditional video communication architectures, the server in a 5G environment needs to deeply coordinate with 5G network capabilities (such as network slicing, MEC, and QoS assurance) to achieve an ultra-high-definition, low-latency, highly reliable, and intelligent video communication experience. It should be noted that the server in this embodiment can also be a server, a cloud server, a remote server, etc.
[0061] In this embodiment of the application, the target terminal device can be a terminal device in 5G video communication state. Specifically, the terminal device (End-User Device / Terminal Device) can be a hardware device that is directly operated by the user for accessing the network, running applications, and obtaining services. For example, the terminal device can include, but is not limited to, mobile phones, tablets, desktop computers, vehicle-mounted systems, etc.
[0062] In some examples, the 5G video communication status can refer to the state of a terminal device conducting video communication in a 5G network environment; for example, the video communication status can include, but is not limited to, the state of a terminal device during video calls, video conferences, live interactive sessions, etc., in a 5G network environment.
[0063] For example, if User 1 and User 2 connect to a video call in a 5G network environment through Terminal Device 1 and Terminal Device 2 respectively, the identification information and encryption information corresponding to Terminal Device 1 and Terminal Device 2 can be obtained respectively; if User 1 and User 3 connect to a video conference in a 5G network environment through Terminal Device 1 and Terminal Device 3 respectively, the identification information and encryption information corresponding to Terminal Device 1 and Terminal Device 3 can be obtained respectively; if User 2 and User 3 conduct live interaction in a 5G network environment through Terminal Device 2 and Terminal Device 3 respectively, the identification information and encryption information corresponding to Terminal Device 2 and Terminal Device 3 can be obtained respectively. Step 202: Generate a text message location command for the target terminal device based on the identification information and encryption information.
[0064] In this embodiment, the SMS location command can be a command sent by the server to the terminal device to trigger the acquisition of location information. Specifically, the SMS location command in this embodiment can include a unique identifier (such as a UUID) and an encryption token. For example, the video call server (i.e., the server in this embodiment) can send an SMS command containing a unique identifier (such as a UUID) and an encryption token to the client terminal (i.e., the target terminal device in this embodiment). The SMS content format can be: GET_LOCATION: <uuid> : <timestamp> : <signature>.
[0065] In this embodiment, a unique identifier is a standard mechanism for generating globally unique IDs in a distributed system without centralized coordination. Its core objective is to ensure that IDs generated by any device at any time are virtually unique, without relying on a central registry.
[0066] In some examples, the encrypted information can specifically be a cryptographic token, a digital credential generated based on cryptographic principles for authentication, authorization, or data protection. It is not a simple string, but a secure object constructed using a key, algorithm, and payload, possessing characteristics such as anti-forgery, anti-tampering, and verifiability. It should be noted that the use of cryptographic tokens in this application embodiment ensures the security of the location determination process.
[0067] For example, if user 1 and user 2 connect to a video call in a 5G network environment via terminal device 1 and terminal device 2 respectively, the identification information and encryption information corresponding to terminal device 1 and terminal device 2 can be obtained respectively. Based on this information, SMS location commands for terminal device 1 and terminal device 2 can be generated respectively.
[0068] As an alternative approach, if User 1 and User 3 connect to a video conference in a 5G network environment through Terminal Device 1 and Terminal Device 3 respectively, the identification information and encryption information corresponding to Terminal Device 1 and Terminal Device 3 can be obtained respectively. Based on the identification information and encryption information corresponding to Terminal Device 1 and Terminal Device 3 respectively, SMS location instructions for Terminal Device 1 and Terminal Device 3 can be generated respectively.
[0069] Step 203: Send a location command via SMS to the target terminal device.
[0070] For example, if user 1 and user 2 connect to a video call in a 5G network environment through terminal device 1 and terminal device 2 respectively, the identification information and encryption information corresponding to terminal device 1 and terminal device 2 can be obtained respectively. Then, based on the identification information and encryption information corresponding to terminal device 1 and terminal device 2 respectively, SMS location instructions for terminal device 1 and terminal device 2 can be generated respectively, and the SMS location instructions for terminal device 1 and terminal device 2 can be sent to terminal device 1 and terminal device 2 respectively.
[0071] As an alternative approach, if User 1 and User 3 connect to a video conference in a 5G network environment through Terminal Device 1 and Terminal Device 3 respectively, the identification information and encryption information corresponding to Terminal Device 1 and Terminal Device 3 can be obtained respectively. Based on the identification information and encryption information corresponding to Terminal Device 1 and Terminal Device 3 respectively, SMS location instructions for Terminal Device 1 and Terminal Device 3 can be generated respectively, and the SMS location instructions for Terminal Device 1 and Terminal Device 3 can be sent to Terminal Device 1 and Terminal Device 3 respectively.
[0072] Step 204: In response to receiving encrypted location information sent by the target terminal device, mark the location of the target terminal device based on the encrypted location information.
[0073] As an optional approach, the server can decrypt the encrypted location information upon receipt. After decryption, the server can update the customer's location marker in the call interface and synchronize it to the backend management system. It should be noted that the location data is only used for this call and is stored in the server's memory rather than in a persistent database.
[0074] Among related technologies, 5G positioning technology (such as triangulation and base station signal model) relies on base station data or dedicated positioning services, which cannot be triggered in real time during video calls. Furthermore, when obtaining location through base station coarse positioning or LPP protocol, there are problems of insufficient accuracy and the need for multiple handshake interactions, making it difficult to meet the real-time requirements of video communication.
[0075] It should be noted that the embodiments of this application can shorten the positioning response time to within 2 seconds through the SMS triggering mechanism, which is a significant optimization compared to the 5-10 second delay of traditional base station positioning; it can support all terminal devices that support 5G SMS function without the need for pre-installed application; the positioning error in open areas can be less than or equal to 5 meters, and the error in indoor scenes can be less than or equal to 20 meters, which is better than the 50-meter error of pure base station positioning.
[0076] It should be noted that the embodiments of this application can also display a dynamic QR code on the call interface, and the user can jump to the system location interface after scanning the code, but this requires the terminal camera to support it; dynamic passwords can also be embedded in the SMS, which requires the customer to enter the password for authorization, and is suitable for high-security scenarios; or a pre-agreed message / password can be replied to in the SMS, which requires the customer to enter the pre-agreed message / password to obtain the geographical location, and is also suitable for high-security scenarios.
[0077] It should be noted that the embodiments of this application can combine timestamps and digital signatures to prevent replay attacks; can also obtain geographical location through operator SMS; can also make dynamic decisions based on signal strength and positioning accuracy; and can also encrypt and transmit location information after local desensitization on the terminal.
[0078] Compared with existing technologies, this embodiment receives a location command sent by the server in response to the target terminal device being in 5G video communication mode, and obtains the location information of the target terminal device based on the location command. This allows the embodiment to initiate the location information acquisition operation in response to the SMS command, reducing the location acquisition delay during video calls and improving the timeliness of location acquisition. This embodiment can also encrypt the location information before sending it by using an encryption format in the SMS location command, improving the security of information transmission and making the location information acquisition process more reliable.
[0079] Furthermore, as Figure 1 To illustrate the specific implementation of the method shown, this embodiment provides a location determination device, such as...
