Description

[Technical Field]

[0001] This invention relates to a data acquisition method, and more particularly to a method for remotely acquiring eSIM profiles, an electronic device, and a computer-readable storage medium. [Previous Technology]

[0002] Traditional Subscriber Identity Modules (SIMs) can no longer meet people's needs for smart and convenient living, leading to the emergence of embedded Subscriber Identity Module (eSIM) technology. Users can open an account through an operator and then use their mobile devices to download and activate the eSIM, enabling independent communication and network connectivity.

[0003] eSIM has the advantages of smaller size and lower power consumption compared to physical SIM cards, but it still cannot get rid of the problem that the distance may be too far when sharing Wi-Fi network with other mobile devices, resulting in the inability to connect. [Summary of the Invention]

[0004] In view of this, the present invention provides a method and electronic device for remotely obtaining eSIM profiles, and an electronic device and computer-readable storage medium, which solves the problem that the function of sharing network connection via Wi-Fi is limited by the Wi-Fi connection distance and signal strength.

[0005] A first embodiment of the present invention provides a method for remotely obtaining an eSIM profile, applied in an electronic device, comprising the following steps: a primary user sends an eSIM profile configuration request to an eSIM management server through a mobile application (APP) of a primary mobile device; the eSIM management server, upon receiving the eSIM profile configuration request from the primary mobile device, transmits at least one eSIM profile to the primary mobile device according to the eSIM profile configuration request; after obtaining the eSIM profile, the primary mobile device encrypts the eSIM profile using its public key and sends the encrypted eSIM profile back to the eSIM management server; a secondary user sends an eSIM profile to the primary mobile device through a mobile application of a secondary mobile device. A primary mobile device sends an eSIM profile download request; upon receiving the eSIM profile download request, the primary mobile device transmits its public key to the secondary mobile device based on the eSIM profile download request; the secondary user sends the eSIM profile download request to the eSIM management server through the secondary mobile device's mobile application, wherein the eSIM profile download request contains the public key; the eSIM management server determines whether it has received the eSIM profile download request; if it has received the eSIM profile download request, the eSIM management server transmits the eSIM profile corresponding to the public key to the secondary mobile device; and after obtaining the eSIM profile, the secondary mobile device decrypts the eSIM profile using the public key and then installs the eSIM profile.

[0006] This embodiment of the invention also provides an electronic device, which includes a memory, a processor, and a program for remotely retrieving eSIM profiles stored in the memory and executable on the processor. When executed by the processor, the program for remotely retrieving eSIM profiles performs the following steps: a primary user sends an eSIM profile configuration request to an eSIM management server via a mobile application (APP) of a primary mobile device; the eSIM management server receives the eSIM profile configuration request from the primary mobile device and transmits at least one eSIM profile to the primary mobile device according to the eSIM profile configuration request; after obtaining the eSIM profile, the primary mobile device encrypts the eSIM profile using its public key and sends the encrypted eSIM profile back to the eSIM management server; A user sends an eSIM profile download request to a master mobile device via a slave mobile device's mobile application; the master mobile device receives the eSIM profile download request and transmits its public key to the slave mobile device according to the eSIM profile download request; the user sends the eSIM profile download request to the eSIM management server via the slave mobile device's mobile application, wherein the eSIM profile download request contains the public key; the eSIM management server determines whether it has received the eSIM profile download request; if it has received the eSIM profile download request, the eSIM management server transmits the eSIM profile corresponding to the public key to the slave mobile device; and after obtaining the eSIM profile, the slave mobile device decrypts the eSIM profile using the public key and then installs the eSIM profile.

[0007] Embodiments of the present invention also provide a computer-readable storage medium storing a computer program that, when executed, implements the steps of the method for remotely obtaining eSIM profiles as described above.

[0013] Figure 1 is a schematic diagram of the architecture of a system for remotely obtaining eSIM configuration files according to an embodiment of the present invention. The system 100 for remotely obtaining eSIM configuration files according to an embodiment of the present invention includes a primary mobile device 110, a base station 120, an eSIM management server 130, and secondary mobile devices 141, 143, and 145. The primary mobile device 110 and the secondary mobile devices 141, 143, and 145 interact with the eSIM management server 130 through the base station 120, respectively.

[0014] Figure 2 is a flowchart of the method for remotely obtaining eSIM configuration files according to an embodiment of the present invention, applied to the processor of an electronic device. Depending on different requirements, the order of the steps in this flowchart can be changed, and some steps can be omitted.

[0015] Step S1: The main user sends an eSIM profile configuration request to the eSIM management server 130 through the mobile application (APP) of the main mobile device 110.

[0016] In step S2, the eSIM management server 130 and the autonomous mobile device 110 receive the eSIM profile configuration request and transmit a preset number of eSIM profiles (e.g., 3 eSIM profiles, eSIM Profile 1 to eSIM Profile 3) to the main mobile device 110 according to the eSIM profile configuration request.

[0017] Step S3: After obtaining the eSIM profiles, the main mobile device 110 encrypts the eSIM profiles using its public key, for example, encrypting the first eSIM profile (eSIM Profile 1), and then transmits the encrypted first eSIM profile to the eSIM management server 130. It should be noted that the main mobile device 110 may also encrypt the eSIM profiles using specific information of the slave users who want to download the eSIM profiles (e.g., the first slave user, the second slave user, and the third slave user) or the slave mobile devices 141, 143, and 145 of these slave users.

[0018] For example, the first eSIM profile to be configured for the slave mobile device 141 can be encrypted a second time based on the face recognition result of the first slave user or the International Mobile Equipment Identity (IMEI) of the slave mobile device 141 (first slave mobile device) of the first slave user to enhance security and ensure that only the slave mobile device 141 can download the first eSIM profile.

[0019] Step S4: When the first user wants to download the first eSIM profile, a first eSIM profile download request is sent from the APP of the mobile device 141 to the main mobile device 110.

[0020] In step S5, the main mobile device 110 receives the first eSIM profile download request and transmits the public key of the main mobile device 110 to the slave mobile device 141 according to the first eSIM profile download request.

[0021] In step S6, the first user sends a second eSIM profile download request to the eSIM management server 130 through the APP of the mobile device 141, wherein the second eSIM profile download request contains the public key.

[0022] Step S7, the eSIM management server 130 determines whether it has received a download request for the second eSIM profile from the mobile device 141.

[0023] In step S8, if a download request for the second eSIM profile is received from the mobile device 141, the eSIM management server 130 will transmit the first eSIM profile corresponding to the public key to the mobile device 141.

[0024] It should be noted that if the primary mobile device 110 uses only its public key to encrypt the eSIM profile, and the eSIM management server 130 has multiple encrypted eSIM profiles, then the eSIM management server 130 may choose any one eSIM profile to send to the secondary mobile device 141. If the primary mobile device 110 uses its public key and the IMEI of the secondary mobile device 141 to encrypt the eSIM profile, then the eSIM management server 130 must send the eSIM profile corresponding to the public key and the IMEI of the secondary mobile device 141 to the secondary mobile device 141.

[0025] Step S9: After obtaining the first eSIM profile from the mobile device 141, the first eSIM profile is decrypted using the public key, and then the first eSIM profile is installed. It should be noted that in step S3, if the first eSIM profile was encrypted using facial recognition results or the IMEI, then the facial recognition results or the IMEI must also be used to decrypt the first eSIM profile during decryption.

In this embodiment, the processor 210 is used to run code stored in the memory 220 or process data, for example, to run the system 230 that remotely retrieves eSIM profiles.

[0029] It should be noted that Figure 3 is only an example to illustrate the electronic device 200. In other embodiments, the electronic device 200 may also include more or fewer elements, or have different element configurations.

[0030] If the modules / units integrated in the electronic device 200 are implemented as software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium.

[0031] FIG4 is a functional block diagram showing an electronic device according to an embodiment of the present invention, which is used to execute a method for remotely obtaining an eSIM profile. The method for remotely obtaining an eSIM profile according to an embodiment of the present invention can be implemented by a computer program in a computer-readable storage medium, for example, memory 220 in electronic device 200. When the computer program implementing the method of the present invention is loaded into memory 220 by processor 210, it drives processor 210 of electronic device 200 to execute the method for remotely obtaining an eSIM profile according to an embodiment of the present invention.

[0032] The electronic device 200 of the present invention, for example, an eSIM management server, includes an eSIM profile configuration module 310 and an eSIM profile transmission module 320.

[0033] The eSIM profile configuration module 310 receives an eSIM profile configuration request from one of the main users' main mobile devices, and transmits a preset number of eSIM profiles to the main mobile device according to the eSIM profile configuration request, and then receives the encrypted eSIM profiles from the main mobile device.

[0034] After obtaining the eSIM profiles, the main mobile device encrypts the eSIM profiles using its public key and sends the encrypted eSIM profiles back to the eSIM profile configuration module 310.

[0035] It should be noted that the primary mobile device can also encrypt the eSIM profile using specific information from one of the users or one of the users' mobile devices that is downloading the eSIM profile.
