[0032] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0033] Embodiment 1

[0034] Figure 1 : is a flow chart of a circuit detection method based on an ESIM card provided by an embodiment of the present invention. The method of this embodiment is automatically executed by an electronic device including an ESIM card, wherein each step can be performed in sequence as shown in the flow chart, or multiple steps can be performed simultaneously according to actual conditions, which is not limited here. The circuit detection method based on an ESIM card provided by the present invention includes:

[0035] Step S101, when a first conversion instruction is received, converting the ESIM card into a radio frequency test card;

[0036] Step S102: Testing the hardware circuit of the electronic device by using the radio frequency test card;

[0037] Step S103: when a second conversion instruction is received, the radio frequency test card is restored to the ESIM card.

[0038] Through the above implementation, first, when the first conversion instruction is received, the ESIM card is converted into a radio frequency test card; then, the hardware circuit of the electronic device is tested by the radio frequency test card; finally, when the second conversion instruction is received, the radio frequency test card is restored to the ESIM card.

[0039] In this embodiment, it should be noted that, considering the technical problem in the prior art that after the whole assembly of the electronic device is completed, the circuit test of the whole device cannot be performed. Therefore, in this embodiment, in order to solve the above technical problem, when the first conversion instruction is received, the ESIM card is converted into a radio frequency test card; the hardware circuit of the electronic device is tested by the radio frequency test card; when the second conversion instruction is received, the radio frequency test card is restored to the ESIM card. After the whole assembly is completed, the ESIM card in the electronic device is converted into a radio frequency test card by the first conversion instruction, and the hardware circuit test of the electronic device is completed based on the radio frequency test card, thereby avoiding the whole machine failure and improving the user experience.

[0040] The above steps will be described in detail below in conjunction with specific implementation methods.

[0041] In step S101, when a first conversion instruction is received, the ESIM card is converted into a radio frequency test card.

[0042] Specifically, when receiving the first conversion instruction, the electronic device including the ESIM card converts its own ESIM card into a radio frequency test card, so as to subsequently perform circuit detection on the whole device based on the radio frequency test card. It can be understood by those skilled in the art that the radio frequency test card can receive the test instruction and feedback the test result in a coupled manner, thereby solving the problem that the test interface of the circuit module is encapsulated inside the electronic device housing and cannot communicate with the test device, and realizing circuit detection of the whole device.

[0043] Optionally, the first conversion instruction is received through a user input unit of the electronic device. That is, the tester can input the first conversion instruction through the user input unit of the electronic device, thereby controlling the electronic device to convert its own ESIM card into a radio frequency test card, so that the electronic device enters a circuit test mode of the whole device. The user input unit can be a button, a touch screen, or a microphone of the electronic device, and the specific type of the user input unit is not limited in this embodiment.

[0044] For example, the tester inputs the first conversion instruction 123# through the key of the electronic device to control the electronic device to convert its own ESIM card into a radio frequency test card and enter the circuit test mode of the whole device.

[0045] In one embodiment, when the first conversion instruction is received, converting the ESIM card into a radio frequency test card includes: when the first conversion instruction is received, decompiling the ESIM card, turning on the authentication of the ESIM card and modifying the encryption key of the ESIM card to a preset key.

[0046] In this embodiment, in order to realize the communication connection between the electronic device and the test device during the circuit detection process of the whole machine, when the electronic device receives the first conversion instruction, it decompiles its own ESIM card, opens the authentication of the ESIM card and modifies the encryption key of the ESIM card to a preset key, so that the electronic device can communicate with the test device based on the preset key, receive the test instruction issued by the test device, and feed back the test result to the test device. Among them, the test device can be a computer or other equipment used for testing, and this embodiment does not limit the specific type of the test device.

[0047] For example, when the electronic device receives the first conversion instruction, it decompiles its own ESIM card, turns on the ESIM card's authentication, NAS Security (Non-Access Stratus Security) and AS Security (Access Stratus Security), and modifies the ESIM card's encryption key to the preset key 000102030405060708090A0B 0C0D 0E0F ​​Hex.

[0048] In step S102, the hardware circuit of the electronic device is tested by the radio frequency test card.

[0049] Specifically, after a communication connection is established between the electronic device and the test device through the radio frequency test card, various tests can be performed on the hardware circuit of the electronic device, for example, TRP (Total Radiated Power), TIS (Total Isotropic Sensitivity), etc. This embodiment does not limit the specific test items.

[0050] In one implementation, the detecting the hardware circuit of the electronic device by using the radio frequency test card includes: detecting the hardware circuit of the electronic device by using the radio frequency test card based on the preset key.

[0051] In this implementation, if the encryption key of the ESIM card has been modified to a preset key when the ESIM card is converted into a radio frequency test card, the electronic device can use the radio frequency test card to detect the hardware circuit of the electronic device based on the preset key. Specifically, the preset key can be used to encrypt the test instructions and test results transmitted between the electronic device and the test device.

[0052] In step S103, when the second conversion instruction is received, the radio frequency test card is restored to the ESIM card.

[0053] Specifically, when receiving the second conversion instruction, the electronic device restores the radio frequency test card to the ESIM card to exit the circuit test mode of the whole device and restore the default function of the ESIM card.

[0054] Optionally, the second conversion instruction is received through a user input unit of the electronic device. That is, the tester can input the second conversion instruction through the user input unit of the electronic device after the test is completed or when an abnormality occurs in the test, thereby controlling the electronic device to restore the RF test card to the ESIM card, so that the electronic device exits the circuit test mode of the whole device.

[0055] For example, after the test is completed or when an abnormality occurs during the test, the tester inputs the second conversion instruction 345# through the button of the electronic device to control the electronic device to restore the RF test card to the ESIM card and exit the circuit test mode of the whole device.

[0056] Optionally, the second conversion instruction is received from the test device via the RF test card. That is, after completing the circuit test of the whole machine, the test device sends the second conversion instruction to the electronic device, so that the electronic device restores the RF test card to the ESIM card, thereby exiting the circuit test mode of the whole machine.

[0057] In one embodiment, when the second conversion instruction is received, restoring the radio frequency test card to the ESIM card includes: when the second conversion instruction is received, restoring the preset key to the encryption key of the ESIM card, and restoring the ESIM card to its initial state before it is converted into the radio frequency test card.

[0058] In this implementation, when the electronic device receives the second conversion instruction, it restores the preset key to the encryption key of the ESIM card, and restores the ESIM card to its initial state before being converted into a radio frequency test card, so as to restore the default function of the ESIM card.

[0059] For example, when the electronic device receives the second conversion instruction, it restores the preset key to the encryption key of the ESIM card, and restores Authentication, NAS Security, and AS Security authentication.

[0060] In one embodiment, please refer to Figure 2 , Figure 2 1 is a flow chart of another circuit detection method based on an ESIM card provided by an embodiment of the present invention. Before converting the ESIM card to a radio frequency test card upon receiving a first conversion instruction, the method further includes:

[0061] Step S104, after the electronic device is powered on, performing a presence detection on the ESIM card;

[0062] Step S105: when the ESIM card is in place, output prompt information about the ESIM card being in place.

[0063] In this embodiment, when performing a circuit test on an electronic device, the electronic device is powered on first, and then the ESIM card is detected to be in place. If the ESIM card is detected to be in place, a prompt message about the ESIM card being in place is output, so that the tester can perform subsequent circuit tests on the whole device after understanding the result of the ESIM card in place detection. For example, if the ESIM card is detected to be in place, the subsequent circuit test of the whole device is performed. If the ESIM card cannot be detected to be in place, the circuit test of the whole device can be directly terminated.

[0064] In one embodiment, after the electronic device is powered on, detecting the presence of the ESIM card includes: after the electronic device is powered on, detecting a level state of an ESIM card detection pin, and determining that the ESIM card is in place when the level state meets a preset condition.

[0065] In this embodiment, an ESIM card detection pin can be set in the electronic device, and when the ESIM card is not inserted or the ESIM card is not recognized, the ESIM card detection pin is set to a low level, and when the ESIM card is inserted or the ESIM card is recognized, the ESIM card detection pin is set to a high level; or, the ESIM card detection pin can also be pulled up to a power supply through a resistor in the electronic device, and when the ESIM card is not inserted, the ESIM card detection pin is a high level, and when the ESIM card is inserted, the pin is pulled down to a low level. It can be understood by those skilled in the art that the level state detection of the ESIM card detection pin can also be implemented in other ways, and this embodiment does not limit the specific way to implement the level state detection of the ESIM card detection pin.

[0066] In an embodiment of the present invention, when a first conversion instruction is received, the ESIM card is converted into a radio frequency test card; the hardware circuit of the electronic device is tested by the radio frequency test card; when a second conversion instruction is received, the radio frequency test card is restored to the ESIM card. When performing circuit testing of the entire device, the ESIM card in the electronic device is converted into a radio frequency test card by the first conversion instruction, and the hardware circuit testing of the electronic device is completed based on the radio frequency test card, thereby avoiding failure of the entire device and improving the user experience.

[0067] Embodiment 2

[0068] Based on the above embodiments, Figure 3 FIG. 1 is a flow chart of another circuit detection method based on an ESIM card provided by an embodiment of the present invention. The method comprises:

[0069] Step S201, after the electronic device is powered on, performing a presence detection on the ESIM card;

[0070] Step S202, determine whether the ESIM card is in place, if yes, execute step S203, otherwise go to step S209;

[0071] Step S203, outputting prompt information about the ESIM card being in place;

[0072] Step S204, determining whether the first conversion instruction is received within a preset time, if yes, executing step S205, otherwise, turning to step S209;

[0073] Specifically, if the electronic device receives the first conversion instruction within the preset time, it converts its own ESIM card into a radio frequency test card and enters the circuit test mode of the whole machine, so as to detect the hardware circuit of the electronic device through the radio frequency test card; if the first conversion instruction is not received within the preset time, it means that the hardware circuit of the electronic device is not being tested. At this time, there is no need to convert the ESIM card into a radio frequency test card, and the circuit detection process based on the ESIM card is directly ended.

[0074] Step S205, converting the ESIM card into a radio frequency test card;

[0075] Step S206, testing the hardware circuit of the electronic device by using the radio frequency test card;

[0076] Step S207, determining whether a second conversion instruction is received, if yes, executing step S208, otherwise, going to step S206;

[0077] Specifically, if the electronic device receives the second conversion instruction, it restores the RF test card to the ESIM card and exits the circuit test mode of the whole machine; if it does not receive the second conversion instruction, it means that the circuit test of the whole machine has not been completed. At this time, the hardware circuit of the electronic device continues to be tested through the RF test card.

[0078] Step S208, restoring the radio frequency test card to the ESIM card;

[0079] Step S209, end the process.

[0080] For example, when the circuit detection method based on the ESIM card of this embodiment is used to detect the circuit of the electronic device, the electronic device is first powered on. After the electronic device is powered on, the ESIM card is detected in place. If the ESIM card is detected in place, the display screen of the electronic device outputs a prompt information about the ESIM card in place, so that the tester can input the first conversion instruction through the keyboard of the electronic device after knowing that the ESIM card is in place, and control the electronic device to convert its own ESIM card into a radio frequency test card. After that, the electronic device is placed in the preset position of the coupling box, and the coupling box is connected to the test equipment and the test instrument respectively. The test equipment runs the automated test script and sends a test instruction to the electronic device through the coupling box and the radio frequency test card; after receiving the test instruction, the electronic device controls its own circuit to work in the working mode corresponding to the test instruction (for example, communicating with the base station in the mode corresponding to the test instruction), and feeds back the test result of the electronic device to the test equipment through the radio frequency test card and the coupling box; the test instrument measures the test data of the electronic device during the circuit detection process through the coupling box, and generates a test report based on the test data and reports it to the test equipment; the test equipment compares the test report with the preset threshold value, determines whether the circuit detection of the electronic device passes according to the preset judgment condition, and outputs the test result so that the tester can know the test result in time. If the test passes, the electronic device can be taken out of the coupling box, and the second conversion instruction can be input through its keyboard. After receiving the second conversion instruction, the electronic device restores the radio frequency test card to the ESIM card. At this point, the circuit detection of the electronic device is completed, and the ESIM card is restored to its default function. It can be understood by those skilled in the art that the preset position of the electronic device in the coupling box can be determined by placing an electronic device with the best indicators and parameters in the coupling box for testing in advance.

[0081] In an embodiment of the present invention, after the electronic device is powered on, the ESIM card is detected in place; when the ESIM card is in place, a prompt message about the ESIM card being in place is output; when a first conversion instruction is received, the ESIM card is converted into a radio frequency test card; the hardware circuit of the electronic device is detected by the radio frequency test card; when a second conversion instruction is received, the radio frequency test card is restored to the ESIM card. When performing circuit detection of the entire device, the ESIM card in the electronic device is converted into a radio frequency test card by the first conversion instruction, and the hardware circuit detection of the electronic device is completed based on the radio frequency test card, thereby avoiding failure of the entire device and improving the user experience.
