[0036] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0037] As described in the background section, manual verification of user QR codes may not be accurate in related technologies. Therefore, this invention provides a QR code recognition method, apparatus, electronic device, and storage medium. The MEC server can determine the account type based on the encrypted information corresponding to the account identifier of an account, and determine whether the account is an abnormal account based on the account type. This enables accurate and effective QR code recognition, improving the effectiveness of QR code recognition.

[0038] The QR code recognition method, apparatus, electronic device, and storage medium provided in this invention can be applied to wireless communication systems. For example, a 5G communication system is used as an example. Figure 1This is a schematic diagram of the network architecture of a 5G communication system provided in an embodiment of the present invention. The 5G communication system may include user equipment (UE) 101, radio access network (RAN) equipment or access network (AN) equipment 102, user plane function (UPF) 103, access and mobility management function (AMF) 104, session management function (SMF) 105, policy control function (PCF) 106, authentication server function (AUSF) 107, network function repository function (NRF) 108, application function (AF) 109, network exposure function (NEF) 110, unified data management (UDM) 111, and network slice selection function (NSSF) 112, etc. UE 101 accesses the 5G network (i.e., UE 101 accesses a 5G system that provides 5G network access) and establishes a session with the network. Then, UE 101 can communicate with the functions that serve UE 101 (such as UPF 103, AMF 104, etc.) through (R)AN device 102. Typically, in practical applications, the connection between the above-mentioned devices or service functions can be a wireless connection or a wired connection. To conveniently and intuitively illustrate the connection relationship between the various devices, Figure 1 Solid lines are used to represent the meaning.

[0039] The (R)AN device 102 is used by UE 101 to access the network. The (R)AN device 102 may include base stations, evolved node base stations (eNB), next-generation node base stations (gNB), new radio eNBs, macro base stations, micro base stations, high-frequency base stations or transmission and reception points (TRP), non-3GPP access networks (such as WiFi), and / or non-3GPP interworking functions (N3IWF), etc.

[0040] UPF 103: Used to handle user plane related events, such as transmitting or routing data packets, detecting data packets, reporting traffic volume, handling quality of service (QoS), lawful interception, and storing downlink data packets. In this embodiment of the invention, UPF 103 can send key parameters of a first account to the MEC server (not shown in the figure), the key parameters of which include the account identifier of the first account.

[0041] AMF 104: Used for connection management, mobility relationships, registration management, access authentication and authorization, reachability management, and security context management. In this embodiment of the invention, AMF 104 can be the key parameters of the first account sent by UE 101 through (R)AN device 102.

[0042] SMF 105: Used for session management (e.g., session establishment, modification, and release), selection and control of UPF 103, selection of service and session continuity modes, and roaming services. In this embodiment of the invention, SMF 105 can receive key parameters of the first account sent by AMF 104 and send the key parameters of the first account to UPF 103.

[0043] PCF 106: Used for formulating strategies, providing strategy control services, and obtaining contractual information related to strategy decisions.

[0044] AUSF 107: Used to interact with UDM 111 to obtain user information and perform authentication-related functions, such as generating intermediate keys.

[0045] NRF 108: Network function text for service discovery, maintaining examples of available network functions, and the services supported by these network functions.

[0046] AF 109: Interacts with the 3GPP core network to provide services or servers; for example, it can interact with NEF 110.

[0047] NEF 110: Securely exposes various services and capabilities provided by 3GPP network functions (including content exposure or exposure to third parties), transforms or translates information interacting with AF 109 and information interacting with internal network functions, such as AF service identifiers and content 5G core network information (e.g., network slice selection assistance information). In this embodiment of the invention, NEF 110 can perform access authentication for MEC servers (not shown in the figure).

[0048] UDM 111: Handles authentication information in 3GPP authentication and key negotiation mechanisms, handles user identity information, access authorization, registration and mobility management, subscription management, and short message management.

[0049] NSSF 112: Used to select a set of network slices for UE 101, determine network slice selection protocol information, and determine the AMF set (AMF set refers to a collection of multiple AMFs that can serve UE 101) for UE 101.

[0050] Optionally, in the embodiments of the present invention, each of the above-mentioned functional modules (i.e., UPF 103, AMF 104, SMF 105, PCF 106, AUSF 107, NRF 108, AF 109, NEF 110, UDM 111, and NSSF 112) can be integrated on the server to realize their functions.

[0051] In combination with the above Figure 1 The 5G communication system shown in the figure, such as Figure 2 As shown, the QR code recognition method, apparatus, electronic device, and storage medium provided in this embodiment of the invention can be applied to a QR code recognition system. Figure 2 As shown, the QR code recognition system includes a UE 101, an (R)AN device 102, a server 201, and a terminal 202. Typically, in practical applications, the connection between these devices or service functions can be wireless. To conveniently and intuitively illustrate the connection relationships between the devices, Figure 2 The diagram uses solid lines. Specifically, server 201 can be a functional network element in the 5G core network (5GC).

[0052] Among them, UE 101 can send data to the AMF in 5GC (e.g., via (R)AN device 102) through (R)AN device 102. Figure 1 The AMF 104 in the 5GC sends the key parameters of the first account, and then the UPF in the 5GC (e.g., Figure 1 The UPF 103 in the first account can send the key parameters of the first account to the server 201. The key parameters of the first account include the account identifier of the first account.

[0053] After receiving the account identifier of the first account, server 201 can encrypt the account identifier to generate encrypted information and determine the QR code type of the first account based on the encrypted information. Additionally, server 201 can also send the account identifier of the first account to terminal 202 via (R)AN device 102.

[0054] After receiving the account identifier of the first account, the terminal 202 can display the account identifier of the first account.

[0055] For example, an electronic device that performs the QR code recognition method provided in the embodiments of the present invention (e.g., the one described above) Figure 2 The terminal 202 shown can be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR) / virtual reality (VR) device. This embodiment of the invention does not impose special limitations on the specific form of the electronic device. It can interact with the user through one or more methods such as a keyboard, touchpad, touchscreen, remote control, voice interaction, or handwriting device.

[0056] Optionally, the above-mentioned electronic devices (e.g., the above-mentioned...) Figure 2 The server 201 shown can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery network (CDN) services, and big data and artificial intelligence platforms.

[0057] In combination with the above Figure 2The QR code recognition system shown below will be described in its entirety from the perspective of the interaction between various devices in the QR code recognition system. This will illustrate the process by which the MEC server determines whether the first account is an abnormal account and the process by which the terminal displays the account identifier of the first account.

[0058] like Figure 3 As shown, the QR code recognition method provided in this embodiment of the invention may include S101-S106.

[0059] S101, the MEC server receives the key parameters of the first account.

[0060] The key parameters of the first account include the account identifier of the first account.

[0061] Based on the description of the above embodiments, it should be understood that the UE corresponding to (or using) the first account can send the key parameters of the first account to the AMF through the (R)AN device. After receiving the key parameters of the first account, the AMF can send the key parameters of the first account to the SMF. After receiving the key parameters of the first account, the SMF can send the key parameters of the first account to the UPF. After receiving the key parameters of the first account, the UPF can send the key parameters of the first account to the MEC server.

[0062] Specifically, when the first account carries the UE into the service area of ​​the (R)AN device (such as a shopping mall or subway station), the UE will send a tracking area update (TAU) procedure. Furthermore, the UE can initiate a protocol data unit (PDU) session request to send the aforementioned key parameters to the network element devices in the 5GC.

[0063] For example, the account identifier of the first account can be the mobile directory number (MDN) of the first account or the identifier of the subscriber identity module (SIM) card of the first account.

[0064] Optionally, NEF can authenticate and identify the MEC server for access. If the authentication is successful, the MEC server can receive the key parameters of the first account.

[0065] S102, the MEC server encrypts the account identifier of the first account and generates encrypted information.

[0066] It should be understood that the MEC server encrypts the account identifier of the first account to protect account privacy and prevent the leakage of account information.

[0067] S103 and MEC servers determine the QR code type of the first account based on encrypted information.

[0068] In one implementation of this invention, the MEC server stores a preset correspondence, which includes multiple encrypted information items and a QR code type corresponding to each of the multiple encrypted information items. Combined with... Figure 3 ,like Figure 4 As shown, the MEC server determines the QR code type of the first account based on encrypted information, which may specifically include S1031.

[0069] S1031, The MEC server will determine the QR code type corresponding to the generated encrypted information in the preset correspondence as the QR code type of the first account.

[0070] Based on the description of the above embodiments, it should be understood that the generated encrypted information is encrypted information generated by the MEC server encrypting the account identifier of the first account.

[0071] For example, Table 1 below is an example of a preset correspondence provided in an embodiment of the present invention.

[0072] Table 1

[0073] Encrypted information QR code type Encrypted message 1 Abnormal QR code Encrypted message 2 Normal QR code Encrypted message 3 Abnormal QR code Encrypted message 4 Normal QR code

[0074] Assuming the generated encrypted information is encrypted information 4, the MEC server determines that the QR code type of the first account is a normal QR code.

[0075] In another implementation of this invention, the MEC server can also send the generated encrypted information to the QR code system. After receiving the encrypted information, the QR code system can decrypt it to obtain the account identifier of the first account. Then, the QR code system can determine the QR code type corresponding to the account identifier of the first account, which is the QR code type of the first account. The QR code system can then send the QR code type of the first account to the MEC server.

[0076] S104. If the QR code type of the first account is an abnormal QR code, the MEC server determines that the first account is an abnormal account and sends the account identifier of the first account to the terminal.

[0077] It should be understood that an account's QR code can be either an abnormal QR code or a normal QR code. If the QR code for the first account is an abnormal QR code, it indicates that the first account is in an abnormal situation, and the MEC server can identify the first account as an abnormal account.

[0078] In one alternative implementation, the color of a normal QR code can be a preset color (e.g., green), while the color of an abnormal QR code can be another color (e.g., red or yellow).

[0079] Understandably, the MEC server can send the account identifier of the abnormal account to the terminal so that the terminal can display the account identifier of the abnormal account.

[0080] Optionally, if the QR code type of the first account is a normal QR code, the MEC server can determine that the first account is a normal account.

[0081] S105, The terminal receives the first account information sent by the MEC server.

[0082] Based on the description of the above embodiments, it should be understood that the account identifier of the first account is sent to the terminal by the MEC server when the QR code type of the first account is an abnormal QR code. The QR code type of the first account is determined by the MEC server based on encrypted information, which is generated by the MEC server through encryption processing of the account identifier of the first account.

[0083] S106. The terminal displays the account identifier of the first account.

[0084] Understandably, the terminal displays the account identifier of the first account so that on-site supervisors in public places can accurately identify the account identifier of the abnormal account and thus monitor the abnormal account (i.e., the first account). For example, prohibiting entry into public places.

[0085] Optionally, the terminal can display the account identifier of the first account in an anonymized manner to avoid disclosing the privacy information of the first account. For example, when the account identifier of the first account is the MDN of the first account, the terminal can only display the last four digits of the MDN.

[0086] The technical solution provided by the above embodiments can bring at least the following beneficial effects: As shown in S101-S106, the MEC server can receive key parameters of the first account, including the account identifier of the first account; then the MEC server can encrypt the account identifier of the first account to generate encrypted information, and determine the QR code type of the first account based on the encrypted information. If the QR code type of the first account is an abnormal QR code, it indicates that the first account is in an abnormal state. The MEC server can determine that the first account is an abnormal account and send the account identifier of the first account to the terminal. In this embodiment of the invention, the MEC server can determine the account type of an account based on the encrypted information corresponding to the account identifier of an account, and determine whether the account is an abnormal account based on the account type, which can accurately and effectively identify the user's QR code and improve the effectiveness of QR code recognition.

[0087] In addition, after receiving the account identifier of the first account sent by the MEC server, the terminal can display that account identifier. This ability to accurately and effectively identify which accounts are abnormal improves the effectiveness of content display and further ensures the security of public places.

[0088] In one implementation of this invention, the key parameters of the first account further include the TAC information of the first account. (Combined with...) Figure 3 ,like Figure 5 As shown, the QR code recognition method provided in this embodiment of the invention may further include S107-S110.

[0089] S107. The MEC server determines the location information of the first account based on the TAC information of the first account.

[0090] In this embodiment of the invention, the TAC information of the first account can also be understood as a list of base stations corresponding to the first account. The list of base stations may include the identifiers of multiple base stations, which are base stations that provide services to the first account.

[0091] Optionally, the MEC server can determine the location information of the first account based on the multiple input multiple output (MIMO) multi-beam characteristics of the base station, and based on indoor positioning technologies such as round trip time (RTT), time difference of arrival (TDOA), angle of arrival (AOA), and departure angle of arrival (DOA) of the cell.

[0092] S108, the MEC server sends the location information of the first account to the terminal.

[0093] S109. The terminal receives the location information of the first account sent by the MEC server.

[0094] S110, The terminal displays the location information of the first account.

[0095] In this embodiment of the invention, the terminal displays the location information of the first account. On the one hand, supervisors in public places can determine the location information that the first account has previously passed through (or arrived at); on the other hand, supervisors can quickly determine the current location information of the first account in order to find the first account as soon as possible.

[0096] Combination Figure 3 ,like Figure 6 As shown, the QR code recognition method provided in this embodiment of the invention may further include S111-S112.

[0097] S111. If the QR code type of the first account is a normal QR code, the MEC server determines whether the location information of the first account exists in the risk location set.

[0098] It should be understood that this set of risky locations includes at least one location information. The location information included in this set of risky locations is used to characterize locations that are off-limits or have a high risk level.

[0099] Understandably, if the QR code type of the first account is a normal QR code, it means that the first account is in a normal state. At this time, the MEC server can determine whether the location information of the first account exists in the risk location set.

[0100] S112. If the location information of the first account exists in the risk location set, the MEC server determines that the first account is an abnormal account.

[0101] It should be understood that if the location information of the first account exists in the risk location set, it means that the location information of the first account is a location that is prohibited from access or has a high risk level. At this time, the MEC server can determine that the first account is an abnormal account.

[0102] Understandably, after the MEC server determines that the first account is an abnormal account, the MEC server can also send the account identifier of the first account to the terminal.

[0103] Optionally, if the location information of the first account exists in the risk location set, the MEC server determines that the first account is a normal account.

[0104] In this embodiment of the invention, the MEC server and terminal can be divided into functional modules according to the above method example. For example, each function can be divided into its own functional module, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module. It should be noted that the module division in this embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation.

[0105] When dividing each function into modules according to its corresponding function. Figure 7 A possible structural schematic diagram of the QR code recognition device involved in the above embodiments is shown, such as... Figure 7 As shown, the QR code recognition device 30 may include: a receiving module 301, a processing module 302, a determining module 303, and a sending module 304.

[0106] The receiving module 301 is used to receive key parameters of the first account, including the account identifier of the first account.

[0107] The processing module 302 is used to encrypt the account identifier of the first account and generate encrypted information.

[0108] The determination module 303 is used to determine the QR code type of the first account based on the encrypted information;

[0109] The determination module 303 is also used to determine that the first account is an abnormal account if the QR code type of the first account is an abnormal QR code.

[0110] The sending module 304 is used to send the account identifier of the first account to the terminal.

[0111] Optionally, the key parameters of the first account may also include the TAC information of the first account.

[0112] The determination module 303 is also used to determine the location information of the first account based on the TAC information of the first account.

[0113] The sending module 304 is also used to send the location information of the first account to the terminal.

[0114] Optionally, the determining module 303 is further configured to determine whether the location information of the first account exists in the risk location set if the QR code type of the first account is a normal QR code.

[0115] The determination module 303 is also used to determine that the first account is an abnormal account if the location information of the first account exists in the risk location set.

[0116] Optionally, the MEC server stores a preset mapping relationship, which includes multiple encrypted information and the QR code type corresponding to each of the multiple encrypted information.

[0117] The determination module 303 is specifically used to determine the QR code type corresponding to the generated encrypted information in the preset correspondence as the QR code type of the first account.

[0118] When using integrated units, Figure 8 A possible structural schematic diagram of the QR code recognition device involved in the above embodiments is shown. For example... Figure 8 As shown, the QR code recognition device 40 may include a processing module 401 and a communication module 402. The processing module 401 can be used to control and manage the operation of the QR code recognition device 40. The communication module 402 can be used to support communication between the QR code recognition device 40 and other entities. Optionally, as shown...
