It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0045] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0046] The terminal will request SUCI from the USIM card in the following situations:

[0047] Scenario 1: When the terminal is in an unregistered state and is preparing to register with the network (e.g., after inserting the USIM card and turning on the device), the terminal requests the USIM card to obtain the SUCI, and then sends a Registration Request message to the Access and Mobility Management Function (AMF), carrying the SUCI to request registration with the network.

[0048] Scenario 2: The terminal receives an Identity Request message from the AMF (e.g., the AMF cannot find the terminal's Subscription Permanent Identifier (SUPI) based on the 5G-GUTI, or the AMF cannot authenticate the terminal, or the SUPI obtained based on the SUCI is unacceptable, etc.). The Identity Request message is used to request the terminal to provide the SUCI. In this case, the terminal will also request the USIM to obtain the SUCI and then reply to the AMF with the SUCI via an Identity Response message.

[0049] The general process for a terminal to obtain SUCI is as follows:

[0050] The terminal sends a request message to the USIM requesting a SUCI. The USIM can determine, based on its configuration, whether to calculate the SUCI itself or have the terminal calculate it. If the USIM calculates the SUCI, it sends the calculated SUCI to the terminal. If the terminal calculates the SUCI, the USIM sends the parameters needed to calculate the SUCI (including SUPI, SUPI type, routing indicator, home network public key identifier, home network public key, and protection scheme identifiers) to the terminal, which then calculates the SUCI based on these parameters.

[0051] However, if the parameters used to calculate the SUCI on the USIM are configured incorrectly, the terminal may be unable to obtain the SUCI for network access, which will prevent the terminal from registering with the network and thus prevent the user from obtaining services. Therefore, this application proposes a method for handling parameter configuration errors.

[0052] The method for handling parameter configuration errors provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0053] Reference Figure 2 This application provides a method for handling parameter configuration errors, as shown in the figure. The method for handling parameter configuration errors includes:

[0054] Step 201: If the parameters for calculating the SUCI (Summary Identity Token) are not configured correctly, the terminal performs the target operation.

[0055] Wherein, the SUCI is used for a first wireless access technology, and the target operation includes at least one of the following:

[0056] Invalid Global Subscriber Identity Card (USIM);

[0057] The first wireless access technology is prohibited;

[0058] The SUCI is generated using the empty algorithm;

[0059] Register using emergency services;

[0060] The network-side device is notified that the parameters for calculating the SUCI have not been configured correctly.

[0061] In this embodiment, the incorrect configuration of the parameters for calculating the Subscription Encryption Identifier (SUCI) can be understood or replaced by an error in the parameter configuration for calculating the SUCI. Specifically, the parameters used to calculate the SUCI can be considered incorrectly configured if at least one of the following conditions is met:

[0062] One or more parameters used to calculate SUCI are not configured or are configured incorrectly;

[0063] The SUCI cannot be calculated based on the configured parameters, or an incorrect SUCI cannot be calculated based on the configured parameters.

[0064] Optionally, an invalid USIM can be understood or replaced with the services of an invalid USIM card, which can protect user privacy and prevent user IDs (such as SUPI) from being exposed due to misconfiguration.

[0065] Optionally, prohibiting the first radio access technology can be understood or replaced by ignoring cells using the first radio access technology during cell selection. In this way, when the first radio access technology is prohibited, the terminal can choose to use a second radio access technology to access the network, thereby ensuring that the terminal can still obtain communication services and guaranteeing communication reliability. Specifically, for the first radio access technology, the terminal needs to use SUCI to access it; for example, in some embodiments, the first radio access technology can be 5G or 6G. For the second radio access technology, the terminal does not need to use SUCI to access it; for example, in some embodiments, the second radio access technology can be 3G or 4G.

[0066] Optionally, using a null algorithm to generate the SUCI can be understood or replaced by using a null scheme to generate the SUCI, so that the terminal can still obtain the service of the first wireless access technology, ensuring the reliability of communication.

[0067] Optionally, registering using emergency services can be understood as accessing the first radio access technology network via emergency services. One implementation involves the terminal sending a registration request message for emergency calls to the network-side equipment. This way, the terminal can still obtain the services of the first radio access technology, ensuring the reliability of communication.

[0068] Optionally, the terminal can notify the network-side device that the parameters of the SUCI have not been correctly configured. This allows the operator to notify the user to upgrade the USIM, thereby ensuring the reliability of subsequent communication.

[0069] It should be noted that the statement that the parameters for calculating the Subscription Encryption Identifier (SUCI) are not configured correctly can be understood as the statement that the information required for SUCI calculation is not correctly configured in the USIM.

[0070] This application embodiment defines the terminal's operational behavior when the parameters for calculating the Subscription Encryption Identity (SUCI) are incorrectly configured. The SUCI is used for a first radio access technology, and the target operation includes at least one of the following: invalidating the Global Subscriber Identity Module (USIM); disabling the first radio access technology; generating the SUCI using a null algorithm; registering using emergency services; and notifying the network-side device that the parameters for calculating the SUCI are incorrectly configured. This clarifies the terminal's operational behavior when the parameters used to calculate the SUCI are incorrectly configured, thereby preventing the user ID (such as SUPI) from being exposed due to misconfiguration or ensuring communication reliability.

[0071] Optionally, in some embodiments, the terminal performing the target operation includes:

[0072] The terminal performs the target operation based on the first information; wherein the first information includes at least one of a target state and user instruction information, the target state being the current state of the terminal, and the user instruction information being used to instruct the user to disable communication services or to allow communication services.

[0073] In this embodiment, a user's blocking of communication services can be understood or replaced as not accepting the risk of privacy leakage, and a user's allowing of communication services can be understood or replaced as accepting the risk of privacy leakage. In other words, the aforementioned user instruction information can also be used to indicate whether or not to accept the risk of privacy leakage.

[0074] In this embodiment, the terminal can obtain its current state and then perform a target operation based on that state. Different states can correspond to different operations. Optionally, the terminal's current state can include a communication state and a communication stage. The communication state can be understood as the terminal's state during communication, and the communication stage can be understood as the terminal's state of receiving or preparing to send messages during communication.

[0075] Optionally, the communication state may include at least one of the following: registered state, unregistered state, no security context, and having a security context. For example, the terminal obtaining its current state can be described as the terminal currently being in a registered or unregistered state, or the terminal currently having or not having a security context.

[0076] Optionally, the communication phase may include receiving an identity request message and sending a registration request. For example, the terminal obtaining its current state can be described as the terminal receiving an identity request message from the network-side device and the terminal sending a registration request to the network-side device.

[0077] Optionally, in some embodiments, the terminal performing the target operation based on the received user instruction information includes at least one of the following:

[0078] If the user instruction information instructs the user to disable communication services, the terminal will have an invalid USIM.

[0079] When the user instruction information instructs the user to allow the communication service, the terminal performs at least one of the following: disables the first wireless access technology; generates the SUCI using a null algorithm; or registers using the emergency service.

[0080] In this embodiment of the application, user instruction information can be obtained by introducing an interface for obtaining user instructions. This allows the user to decide whether to allow the communication service. If the communication service is allowed, the reliability of subsequent communication can be guaranteed. If the communication service is prohibited, the risk of privacy leakage can be reduced.

[0081] It should be noted that since the terminal cannot determine the user's preferences, by introducing an interface to obtain user instructions, the terminal can acquire user instruction information and perform targeted operations based on this information, thus achieving a balance between privacy protection and service access. Furthermore, obtaining the terminal's current state can serve as a prerequisite for implementing certain interactive actions, enabling the terminal to behave appropriately in different states.

[0082] Optionally, in some embodiments, when the first information includes the user instruction information, the method further includes:

[0083] The terminal displays error configuration information, which is used to obtain the user instruction information.

[0084] Optionally, in some embodiments, the error configuration information is used to indicate at least one of the following: the parameters of the SUCI are not configured correctly, and the SUCI is updated.

[0085] In this embodiment, the terminal can display error configuration information via a pop-up window, allowing the user to choose whether to allow communication services or accept the risk of privacy leakage. For example, in some implementations, error configuration information can be displayed via a pop-up window to indicate that the parameters for calculating the SUCI have not been configured correctly or to indicate that the SUCI needs to be updated. The user can input their selection via operation buttons or voice, such as displaying a first operation button and a second operation button on the pop-up window. The first operation button is associated with allowing communication services and accepting the risk of privacy leakage; the second operation button is associated with disallowing communication services and not accepting the risk of privacy leakage. When the user selects the first operation button, user instruction information is generated to instruct the user to allow communication services or accept the risk of privacy leakage; when the user selects the second operation button, user instruction information is generated to instruct the user to disable communication services or not accept the risk of privacy leakage.

[0086] For example, the terminal displays a dialog box to the user, saying, "Your current USIM card is not configured correctly. Continuing to use it may pose a risk of privacy leakage. Do you want to continue using it? You can contact your operator to replace your USIM card." If the user clicks "Yes," the terminal obtains user instruction information from the user indicating that communication services are allowed. If the user clicks "No," the terminal obtains user instruction information from the user indicating that communication services are prohibited.

[0087] Optionally, in some embodiments, when the first information includes the target state, the terminal performing the target operation based on the target state information includes at least one of the following:

[0088] When the target state is the first state, the terminal disables the first wireless access technology;

[0089] When the target state is the second state, the terminal notifies the network-side device that the parameters for calculating the SUCI have not been configured correctly.

[0090] The first state includes at least one of the following: non-registered state, no security context, or ready to send a registration request;

[0091] The second state includes at least one of the following: registered state, having a security context, or receiving an identity request.

[0092] In this embodiment, when the terminal's target state is the first state, it can be determined that the first wireless access technology is prohibited, but the terminal can still select the second wireless access technology. When the terminal's target state is the second state, it can be determined that the parameters for calculating the SUCI have not been correctly configured and the network-side device is notified.

[0093] Optionally, in some embodiments, when the first information includes the target state and the user indication information, the terminal performing the target operation based on the first information includes:

[0094] When the user instruction information instructs the user to allow the communication service, the terminal performs at least one of the following: disables the first wireless access technology; generates the SUCI using a null algorithm; or registers using the emergency service.

[0095] If the target state indicates that the terminal has obtained the target cause value, the terminal invalidates the USIM;

[0096] The target cause value is used to indicate that the terminal is invalid.

[0097] Optionally, if the target state indicates that the terminal has obtained the target cause value, invalidating the USIM by the terminal includes: if the terminal first performs registration and obtains the target cause value sent by the network-side device based on the registration, then the terminal invalidates the USIM. In other words, the aforementioned target state is that the terminal has obtained the target cause value.

[0098] For example, if the user instruction information instructs the user to allow communication services, and the terminal blocks the first radio access technology, the terminal can register or attach to a second radio access technology network (e.g., attach to a 4G network). If the user instruction information instructs the use of a null algorithm to generate the SUCI, then the null algorithm is used to generate the SUCI, and the terminal registers to the first radio access technology network (e.g., registers to a 5G network) based on the generated SUCI. If the user instruction information instructs the use of emergency services for registration, then emergency services are used to register to the first radio access technology network (e.g., registers to a 5G network). After registration or attachment, the network-side device can send a target cause value to the terminal indicating that the terminal is invalid (e.g., the network may not be able to find a valid SUPI due to a misconfigured SUPI, thus indicating that the terminal is invalid; this target cause value can be sent via an identity response message or a NAS rejection message). The terminal invalidates the USIM (or disables the USIM card) based on this target cause value.

[0099] Optionally, in some embodiments, when the user instruction information in the first information packet is received, the terminal performing the target operation based on the first information includes:

[0100] When the user instruction information instructs the user to allow the communication service, the terminal performs at least one of the following: disables the first wireless access technology; generates the SUCI using a null algorithm; or registers using the emergency service.

[0101] Furthermore, if the terminal obtains the target cause value, the terminal invalidates the USIM;

[0102] The target cause value is used to indicate that the terminal is invalid.

[0103] Optionally, in some embodiments, the method further includes:

[0104] The terminal sends a first request message to the USIM, the first request message being used to request SUCI;

[0105] The terminal receives the first response message corresponding to the first request message;

[0106] The terminal determines, based on the first response message, that the parameters for calculating the SUCI have not been configured correctly.

[0107] It should be noted that in some embodiments, if the USIM finds that the parameters for calculating SUCI are not configured correctly, the USIM sends a first response message carrying an error reason value to the terminal. The error reason value is used to indicate that the parameters for calculating SUCI are not configured correctly, and the terminal determines that the parameters for calculating SUCI are not configured correctly based on the error reason value.

[0108] In some embodiments, if the USIM does not find that the parameters used to calculate SUCI are not configured correctly, the USIM may send a first response message carrying the parameters used to calculate SUCI to the terminal, and the terminal determines that the parameters used to calculate SUCI are not configured correctly based on the parameters used to calculate SUCI.

[0109] Optionally, in some embodiments, the invalid USIM includes:

[0110] Invalidate the service of the first wireless access technology associated with the USIM.

[0111] Optionally, invalidating the service of the first radio access technology associated with the USIM can be understood or replaced by invalidating the service of the first radio access technology network, such as invalidating 5G network service or invalidating 6G network service.

[0112] Optionally, in some embodiments, the prohibition of the first wireless access technology includes:

[0113] Cells using the first wireless access technology are ignored during the cell selection process.

[0114] In this embodiment of the application, during the cell selection process, since cells using the first wireless access technology are ignored, cells using the second wireless access technology can still be used, thereby continuing to provide network services using the second wireless access technology.

[0115] Optionally, in some embodiments, after generating the SUCI using the empty algorithm, the method further includes:

[0116] The terminal sends the SUCI to the network-side device.

[0117] For example, when the network-side device is an AMF, the terminal can send a registration request message to the AMF, and the registration request message includes the SUCI.

[0118] Optionally, in some embodiments, the notification to the network-side device that the parameters for calculating the SUCI are not correctly configured includes:

[0119] A second message is sent to the network-side device. The second message contains a second reason value, which indicates that the parameters for calculating the SUCI have not been configured correctly.

[0120] Optionally, the second reason value can also be used to indicate that the SUCI was generated according to the empty algorithm.

[0121] For example, when the network-side device is an AMF (Application Management Function), the terminal can send an uplink NAS message, such as a registration request message or an identity response message, to the AMF, carrying a second cause value in the NAS message to indicate that the parameters for calculating the SUCI have not been configured correctly. The AMF can also determine whether the SUCI was specially generated based on the second cause value, and thus take special actions, such as using a null algorithm to decrypt the SUCI or using backup subscription information. The AMF can record the error cause value for the terminal and notify the user to update the configuration information on the USIM via out-of-band means (such as telephone or SMS).

[0122] In this embodiment, the network-side device can take special processing based on the second cause value, such as using an empty algorithm to decrypt SUCI and notifying the operator so that the operator can notify the user to upgrade the USIM, thereby ensuring the reliability of subsequent communication.

[0123] To better understand this, we will use some examples below.

[0124] In some embodiments, assuming the first radio access technology is 5G and the second radio access technology is 4G or LTE radio access technology (RAT), the relevant process for calculating SUCI parameters not being configured correctly includes the following steps:

[0125] 1. The terminal sends a request message to USIM requesting SUCI;

[0126] Optionally, the terminal may send a request message to USIM requesting SUCI before initiating a registration request message;

[0127] Optionally, after receiving the identity request message, the terminal may send a request message to USIM to request SUCI.

[0128] 2. USIM sends a response message to the terminal, and the terminal determines from the response message that the parameters for calculating SUCI have not been configured correctly. The terminal determines that the parameters for calculating SUCI have not been configured correctly based on the response message in the following situations:

[0129] Scenario 1: If USIM finds that the parameters for calculating SUCI are not configured correctly, USIM sends an error reason value to the terminal. The error reason value indicates that the parameters for calculating SUCI are not configured correctly, and the terminal determines that the parameters for calculating SUCI are not configured correctly based on the error reason value.

[0130] Scenario 2: If USIM does not find that the parameters for calculating SUCI are not configured correctly, USIM sends the parameters for calculating SUCI to the terminal. The terminal determines that the parameters for calculating SUCI are not configured correctly based on the parameters for calculating SUCI.

[0131] 3. Optionally, the terminal may obtain user instruction information if the parameters for calculating SUCI are not configured correctly.

[0132] Optionally, the user-instructed terminal can instruct the user to block or allow communication services, or to accept or reject the risk of privacy breaches.

[0133] The terminal can display error configuration information to the user and then obtain user instructions. The error configuration information indicates a USIM card configuration error. It can also prompt for a USIM update.

[0134] For example, the terminal displays a dialog box to the user, saying, "Your current USIM card is not configured correctly. Continuing to use it may pose a risk of privacy leakage. Do you want to continue using it? You can contact your operator to replace your USIM card." If the user clicks "Yes," the ME obtains user instruction information from the user indicating that communication services are allowed. If the user clicks "No," the terminal obtains user instruction information from the user indicating that communication services are prohibited.

[0135] 4. Optionally, the terminal obtains its current state if the parameters for calculating SUCI are not configured correctly. The current state indicates the terminal's current status and may include information about the terminal's status during communication or its status when receiving or preparing to send messages during communication.

[0136] 5. The terminal determines the subsequent action based on at least one of the user's instruction information and the current state, including one or more of the following:

[0137] 1) Invalid USIM (or 5G service of an invalid USIM card);

[0138] 2) 5G RAT is disabled (LTE RAT is allowed), meaning that ME ignores 5G RAT cells during cell selection.

[0139] 3) Generate SUCI using the empty algorithm;

[0140] 4) Use emergency services to access the 5G network;

[0141] 5) Notify AMF of error messages, which indicate that the parameters for calculating the SUCI have not been configured correctly.

[0142] Optionally, specific implementations include the following:

[0143] 1) The terminal disables the USIM card based on user instructions that prohibit communication services or do not accept privacy risks.

[0144] 2) The terminal accesses the 5G network by allowing communication services or accepting the risk of privacy leakage according to the user's instructions, using an empty algorithm to generate SUCI, or by prohibiting 5G RAT or using emergency services.

[0145] 3) The terminal determines that it is prohibited to select 5G RAT based on at least one of the following: the current state is non-registered, there is no security context, and the terminal is ready to send a RegistrationRequest. However, the terminal can still select 4G or LTE RAT.

[0146] 4) The terminal determines the AMF error information based on at least one of the following: its current state is registered, it has a security context, and it has received an Identity request. The terminal can send an uplink NAS message to the AMF, carrying an error reason value indicating that the parameters for calculating SUCI have not been configured correctly. The AMF can record this error reason value for the UE and notify the user to update the configuration information on the USIM via out-of-band means (e.g., telephone, SMS).

[0147] 5) The terminal allows communication services or accepts the risk of privacy leakage according to the user's instructions, and uses an empty algorithm to generate SUCI, or blocks 5G RAT or uses emergency services to access the 5G network; wherein, the terminal receives an error reason value from the AMF again to indicate that the UE is illegal (possibly because the SUPI is misconfigured, causing the network to not find a valid SUPI, thus indicating that the UE is illegal), and the terminal blocks the USIM card according to the error reason value.

[0148] It should be noted that the above user instructions and current status are optional and include, but are not limited to, the above current status.

[0149] Regarding situations 1) and 2) above: obtaining user instruction information by the terminal can achieve a balance between privacy protection and service access, since the terminal cannot determine the user's preferences, thus introducing an interface for obtaining user instructions.

[0150] Regarding situations 3) and 4) above: The terminal obtaining the current state can serve as a prerequisite for implementing some interactive actions, so that the terminal can have reasonable operational behavior in different states.

[0151] By blocking USIM cards, user privacy can be protected and user IDs (such as SUPI) can be prevented from being exposed due to misconfiguration.

[0152] For scenarios 2), 3), and 4), the terminal can still obtain communication services. For scenarios 2) and 4), the terminal can still obtain 5G services. For scenario 3), the UE can obtain 4G services (but 5G services are disabled). Since 4G itself does not have a SUPI protection mechanism, this method can be used without requesting the user's instructions.

[0153] Regarding situation 5) above, notifying the AMF can provide a means for network-side devices to know that the USIM card is misconfigured, thereby enabling the operator to notify the user to upgrade the USIM.
