[0020] In order to make the purpose, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

[0021] In one embodiment, Figure 1As shown, a method for identity authentication of a user terminal is provided. This embodiment mainly uses the method applied to a user terminal as an example. Among them, the user terminal disclosed in the present invention may include but is not limited to a mobile phone, a tablet computer, etc. Among them, the identity authentication method of the user terminal applied to the user terminal may have at least two user identification cards built-in, for example, one user identification card is for accessing the network using the Code Division Multiple Access (CDMA) mode (hereinafter referred to as C mode), and the other user identification card is for accessing the network using the Global System for Mobile Communications (GSM) mode (hereinafter referred to as G mode). Using the method of the embodiment of the present disclosure to perform identity authentication of the user terminal can avoid the user from manually switching the SIM card, thereby ensuring the communication stability of the user terminal and avoiding communication interruption affecting the user's communication experience.

[0022] like Figure 1 As shown, the identity authentication method of the user terminal includes:

[0023] Step 101: Read the user identity identification file in the first user identification card.

[0024] The user identity identification file is used to identify the unique identity information of the user terminal, including the International Mobile Subscriber Identity (IMSI) file.

[0025] In one embodiment of the present disclosure, user identity information in a first user identification card is read, wherein the first user identification card can be understood as a user identification card that is pre-set for priority use by the user terminal. For example, when the first user identification card is a C-mode user identification card that adopts the CDMA mode to access the communication network, and the second user identification card is a G-mode user identification card that adopts the GSM mode to access the communication network, the user terminal adopts the CDMA mode to access the network by default.

[0026] In this embodiment, in order to facilitate timely detection of damage to the user identity identification file in the first user identification card, the user identity identification file in the first user identification card can be read at a preset time interval, wherein the preset time interval can be set according to the scenario, for example, the user identity identification file in the first user identification card is 1 second.

[0027] Step 102: When the user identification file in the first user identification card fails to be read, the user identification file in the second user identification card is read, wherein the user identification information of the user terminal contained in the user identification file in the first user identification card is the same as the user identification information of the user terminal contained in the second user identification card.

[0028] In one embodiment of the present disclosure, when the user identity identification file in the first user identification card fails to be read, the user identity identification file in the second user identification card is read. The user identity identification information of the user terminal contained in the user identity identification file in the first user identification card is the same as the user identity identification information of the user terminal contained in the second user identification card, that is, the user identity identification information contained in the two user identification cards is the same identity identification information of the user terminal. For example, the user identity identification file in the first user identification card is a C-mode IMSI file, and the user identity identification file in the second user identification card is a G-mode IMSI file, etc. In this embodiment, when the user identity identification file in the first user identification card fails to be read, the user identity identification file in the second user identification card is automatically read. The card reader module in the user terminal can be used to read the user identity identification file.

[0029] Step 103 : When the user identity identification file in the second user identity card is read successfully, an identity authentication operation of the user terminal is performed according to the user identity identification file in the second user identity card.

[0030] In one embodiment of the present disclosure, when the user identification file in the second user identification card is read successfully, an identity authentication operation of the user terminal is performed according to the user identification file in the second user identification card.

[0031] In another embodiment of the present disclosure, when the user identification file in the first user identification card is read successfully, the identity authentication operation of the user terminal is performed according to the user identification file in the first user identification card.

[0032] In different application scenarios, the steps for performing the above identity authentication operation are different. In some possible embodiments, for example, Figure 2 As shown in the figure, the authentication operation of the user terminal includes:

[0033] Step 201: Parse the successfully read user identification file to obtain user identification information.

[0034] The user identification information may include: mobile country code, mobile network code, mobile user identification code and other information that uniquely identifies the user terminal identity and the mobile network it is connected to.

[0035] In an embodiment of the present disclosure, the successfully read user identification file is parsed to obtain user identification information.

[0036] Step 202: Feedback the user identification information to the identity authentication device, wherein the identity authentication device performs identity authentication of the user terminal according to the user identification information.

[0037] Among them, the identity authentication device is related to the specific communication scenario. For example, when the user terminal communicates, it accesses the mobile communication network through a nearby base station. Therefore, the base station will send an identity authentication request to the user terminal. Therefore, the identity authentication device can be a base station.

[0038] In an embodiment of the present disclosure, user identity recognition information is fed back to an identity authentication device, wherein the identity authentication device performs identity authentication of the user terminal according to the user identity recognition information.

[0039] In order to more intuitively display the identity authentication process of the user terminal, in one embodiment of the present disclosure, the reading process of the user identity identification file can be displayed.

[0040] In this embodiment, the user identity identification file reading prompt information of the first user identification card is displayed on the preset display interface, wherein the user identity identification file reading prompt information may include the identification card identifier of the first user identification card and the reading progress of the user identity identification file, etc., thereby, the user can intuitively know which user identification card is currently being identified and the identification progress on the preset display interface.

[0041] In this embodiment, when the user identity identification file in the first user identification card fails to be read, a prompt message indicating that the user identity identification file reading failure of the first user identification card is failed is displayed on a preset display interface. The style of the prompt message indicating that the user identity identification file reading failure is failed includes but is not limited to one or more of text, color, letters, pattern, animation, etc.

[0042] Similarly, in one embodiment of the present disclosure, user identity identification file reading prompt information of the second user identification card can also be displayed on the preset display interface, wherein the user identity identification file reading prompt information may include the identification card identifier of the second user identification card and the reading progress of the user identity identification file, etc., thereby, the user can intuitively know which user identification card is currently being identified and the identification progress on the preset display interface.

[0043] In this embodiment, when the user identification file in the second user identification card is successfully read, a prompt message indicating that the user identification file of the second user identification card has been successfully read is displayed on a preset display interface. The prompt message may be in one or more of the following formats: text, color, letter, pattern, animation, etc.

[0044] In one embodiment of the present disclosure, when the user identity identification file in the first user identification card fails to be read, a replacement reminder message for the first user identification card is also displayed on the terminal interface of the user terminal to intuitively remind the user to replace the first user identification card. If the user does not confirm the replacement reminder message after a first preset time, the displayed replacement reminder message for the first user identification card is closed so as not to affect the user's use of the terminal device. The replacement reminder message for the first user identification card is displayed after a preset time. If the user does not confirm the replacement reminder message after a second preset time, the displayed replacement reminder message for the first user identification card is closed so as not to affect the user's use of the terminal device, and the replacement reminder message for the first user identification card is no longer displayed. In order to ensure that the user can be informed of the file damage of the first user identification card, the second preset time is longer than the first preset time.

[0045] In another embodiment of the present disclosure, when the user identification file of the first user identification card is successfully read, the user terminal's identity authentication operation can be directly performed based on the user identification file in the first user identification card. Furthermore, to ensure communication stability of the terminal device when switching to the second user identification card, the user identification file of the second user identification card can also be read. If the user identification file in the second user identification card fails to be read, a reminder message to replace the second user identification card is displayed on the terminal interface of the user terminal.

[0046] In summary, the user terminal authentication method of the disclosed embodiment reads a user identity file from a first user identification card. If reading the user identity file from the first user identification card fails, the user identity file from a second user identification card is read. If reading the user identity file from the second user identification card succeeds, the user terminal's authentication operation is performed based on the user identity file from the second user identification card. In this technical solution, the user does not need to actively switch user identification cards. If reading the user identity file from one user identification card in the user terminal fails, the user identity file from another user identification card is actively read, thereby ensuring communication stability of the user terminal.

[0047] It should be understood that although Figure 1-2 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders.
