Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of communication technologies, and in particular to a method for downloading a profile, a terminal, and a storage medium.

Background Art

[0002] A Subscriber Identity Module (SIM) is independent of a mobile terminal. By inserting a SIM card into the mobile terminal, the mobile terminal can access a data network. On the other hand, an Embedded-SIM (eSIM) card is generally embedded inside a mobile terminal and can replace the SIM card. On the other hand, although the eSIM card cannot be inserted or removed, by downloading profiles of different operators to the eSIM card, the purpose of card or operator switching can be achieved. However, because a certain mobile terminal is limited by the applicable scenario and does not support wireless network communication technology (Wi-Fi) or Bluetooth (registered trademark) technology, thus, it is difficult for the eSIM card of the mobile terminal to quickly and effectively download the profile, and the user experience deteriorates. Therefore, how to improve the convenience and accuracy of profile downloading is an urgent problem to be solved currently.

[0008] The following describes the technical concepts in the embodiments of this disclosure clearly and completely, linking them with the drawings of the embodiments of this disclosure. Clearly, the embodiments described are some, but not all, embodiments of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure, without any creative effort on their part, fall within the scope protected by the embodiments of this disclosure.

[0009] The flowcharts shown in the diagrams are merely illustrative and do not necessarily have to include all content and operations / steps, nor do they have to be performed in the order they are described. For example, certain operations / steps may be further broken down, combined, or partially merged, and therefore the actual order in which they are performed may change depending on the actual situation.

[0010] It should be understood that the terminology used in the description of the embodiments of this disclosure is merely for the purpose of describing specific embodiments and is not intended to limit the embodiments of this disclosure. As used in the description and claims of the embodiments of this disclosure, unless the context explicitly indicates otherwise, the singular forms “one,” “one,” and “the said” are intended to include the plural form.

[0011] Embodiments of this disclosure provide a method for downloading a profile, a terminal, and a storage medium. The method for downloading the profile can be applied to a mobile terminal, which may be a mobile phone, tablet, laptop, desktop computer, or wearable device. For example, if the mobile terminal is a mobile phone, after the mobile phone is powered on, if the eSIM card is not activated and a SIM card is inserted, a command to download the eSIM card profile is sent to a server using the SIM card's communication network. The target profile returned by the server based on the profile download command is retrieved, the target profile is written to the eSIM, and the eSIM card is activated.

[0012] Hereinafter, several embodiments of the embodiments of this disclosure will be described in detail with reference to the drawings. The embodiments and features described below can be combined with each other, as long as they do not conflict with each other.

[0013] Refer to Figure 1, which is a flowchart of the method for downloading a profile according to an embodiment of the present disclosure.

[0014] As shown in Figure 1, the method for downloading the profile may include steps S101 to S102.

[0015] In step S101, after the mobile terminal is powered on, if the eSIM card is not activated and a SIM card is inserted, a command to download the eSIM card profile is sent to the server using the SIM card's communication network, and the SIM card is used to provide the communication network.

[0016] Here, the mobile terminal may include an eSIM card and a card slot, the card slot being used for inserting a SIM card to provide a communication network. The card slot may be installed in accordance with the actual circumstances, and the embodiments of this disclosure are not specifically limited thereto, for example, the card slot may be located in the bottom region of the mobile terminal. For example, as shown in Figure 2, mobile terminal A includes an eSIM card B and a card slot C, the eSIM card B being embedded in the circuit board in the upper left of mobile terminal A, and the card slot C being located on the right side of the mobile terminal, card Slot C is used for inserting a SIM card.

[0017] In the embodiments of this disclosure, the eSIM card profile is a Profile, and that is, in the embodiments of this disclosure, the profile downloaded for the eSIM card is the Target Profile.

[0018] In one embodiment, after the mobile terminal is powered on, application information and file information of the eSIM card are acquired. The application information includes information such as International Mobile Subscriber Identity (IMSI) or Universal Subscriber Identity Module (USIM), and the file information includes information such as Internet information and profile list. Based on the file information, it is determined whether or not the eSIM card has been activated. By acquiring the file information of the eSIM card, it is possible to accurately determine whether or not the eSIM card has been activated.

[0019] In one embodiment, a method for determining whether an eSIM card has been activated based on file information may involve obtaining a profile list for the eSIM card from the file information and determining whether the eSIM card has been activated based on the profile list. Here, the profile list is a list of profile sets included in the eSIM card, and the types of profiles included in the profile list may be set according to the actual situation, and the embodiments of this disclosure are not specifically limited thereto, for example, the types of profiles may include test profiles and access network profiles. Based on the profile list, it is possible to accurately determine whether the eSIM card has been activated.

[0020] In one embodiment, the method for determining whether an eSIM card has been activated based on a profile list may involve determining whether a profile of a pre-configured type exists in the profile list, determining that the eSIM card has been activated if such a profile exists, or determining that the eSIM card has not been activated if such a profile does not exist. Here, the pre-configured type may be set according to the actual situation, and the embodiments of this disclosure are not specifically limited thereto; for example, the pre-configured type may be an operational type. By determining whether a profile of a pre-configured type exists in the profile list, it is possible to accurately determine whether an eSIM card has been activated.

[0021] In one embodiment, when it is determined that the eSIM card is not activated, it is determined whether a SIM card is inserted. When it is determined that the SIM card is not inserted, preset prompt information is transmitted to prompt the user that the SIM card is not inserted in the mobile terminal. When the user receives that the SIM card is not inserted, the user inserts the SIM card into the mobile terminal. Here, the preset prompt information may be set according to the actual situation, and the embodiments of the present disclosure are not specifically limited thereto. For example, for the preset prompt information, the mobile terminal may announce the voice that the SIM card is not inserted or display the character information that the SIM card is not inserted on the display screen of the mobile terminal. When it is detected that the SIM card is not inserted, the user can be promptly prompted to insert the SIM card, and the efficiency of downloading the profile can be improved.

[0022] Note that the method for determining whether a SIM card is inserted may be set according to the actual situation, and the embodiments of the present disclosure are not specifically limited thereto. For example, it is determined whether SIM card information can be obtained. When SIM card information can be obtained, it is determined that the SIM card is inserted, or when it is detected that the detection identifier of the SIM card in the mobile terminal is at the first identifier, it is determined that the SIM card is inserted into the card slot.

[0023] In one embodiment, after the mobile terminal is powered on, if the eSIM card is not activated and a SIM card is inserted, it is determined whether the SIM card has registered for a communication network service. If the SIM card has not registered for the communication network service, a request to register the SIM card for the communication network service is sent, and it is requested that the server matching the SIM card register the communication network service based on the request for the SIM card to register the communication network service. If it is determined that the SIM card has not registered for the communication network service, the SIM card is controlled to register the communication network service with the server, improving the efficiency and accuracy of the mobile terminal downloading the profile.

[0024] In one embodiment, the mobile terminal includes a Local Provisioning Assistant (LPA). When it is determined that the SIM card has registered for a communication network, the LPA is controlled to establish a communication connection with the server using the communication network of the SIM card and send a download command for the profile of the eSIM card to the server through the communication connection. By controlling the LPA to send a download command for the profile of the eSIM card to the server using the communication network of the SIM card, the efficiency and accuracy of downloading the profile can be improved.

[0025] In one embodiment, the LPA establishes a communication connection with a server using a pre-configured connection method via the SIM card's communication network. After the mobile terminal establishes the communication connection with the server, it controls the communication connection to send a command to the server to download the eSIM card profile. Here, the pre-configured connection method may be selected according to the actual situation, and the embodiments of this disclosure are not specifically limited thereto. For example, the pre-configured connection method may be a method that establishes a communication connection with the server by scanning the server's 2D code, or a method that establishes a communication connection with the server by accessing the network address corresponding to the server.

[0026] For example, when it is determined that the SIM card has registered with a communication network, the LPA obtains a QR code from the server, identifies the QR code information, and controls the LPA to establish a communication connection with the server using the SIM card's communication network and the QR code information. After the LPA establishes the communication connection with the server, it sends a command to the server to download the eSIM card profile via the communication connection. The QR code on the server ensures that the communication connection with the server is established accurately, significantly improving the efficiency and accuracy of downloading the profile.

[0027] For example, when it is determined that the SIM card has registered a communication network, the LPA obtains the server's network address and controls the SIM card's communication network to establish a communication connection with the server using that network address. After the mobile device establishes a communication connection with the server, the LPA sends a command to the server to download the eSIM card profile via the communication connection. This ensures that a communication connection with the server is accurately established using the server's network address, significantly improving the efficiency and accuracy of profile downloads.

[0028] In one embodiment, if it is detected that an application program other than the LPA is using the SIM card's communication network, the system prohibits each application program other than the LPA from using the SIM card's communication network. By prohibiting application programs other than the LPA from using the SIM card's communication network, the role of the SIM card becomes solely for the eSIM card to download profiles, improving the efficiency and accuracy of the eSIM card's profile download.

[0029] For example, a mobile terminal includes an LPA, application program 1, application program 2, application program 3, and application program 4, and if the LPA and application program 2 request to use the SIM card's communication network, the request by application program 2 is prohibited, and the LPA is allowed to use the SIM card's communication network to send a command to the server to download the eSIM card profile.

[0030] In one embodiment, after the mobile terminal is powered on, it is determined whether the eSIM card has been activated. If the eSIM card has not been activated, it is determined whether the mobile terminal is connected to a Wi-Fi hotspot. If the mobile terminal is not connected to a Wi-Fi hotspot, it is determined whether a SIM card has been inserted. If a SIM card has been inserted, a command to download the eSIM card profile is sent to the server using the SIM card's communication network. If the eSIM card has not been activated and the mobile terminal is not connected to a Wi-Fi hotspot, a command to download the eSIM card profile is sent to the server using the SIM card's communication network, significantly improving the convenience and efficiency of downloading the profile.

[0031] In step S102, the server retrieves the target profile that it has returned based on the profile download command, writes the target profile to the eSIM card, and activates the eSIM card.

[0032] Here, the target profile is the profile on which the mobile device's eSIM card registers its business operations, and this target profile includes data such as the file system, access network key parameters, support security domains, and applications.

[0033] In one embodiment, the SIM card's communication network sends a command to the server to download the eSIM card profile, the server receives the download command, obtains the target profile based on the download command, the server returns the target profile to the mobile terminal via the SIM card's communication network, the mobile terminal writes the target profile to the eSIM card and activates the eSIM card. The mobile terminal receives the target profile returned by the server, writes the target profile to the eSIM card and activates the eSIM. card This significantly improves the convenience and efficiency of downloading and activating the target profile.

[0034] In one embodiment, the method for obtaining the target profile based on the profile download command may involve obtaining a pre-configured mapping relationship table between the profile download command and the profile, querying the profile corresponding to the profile download command from the mapping relationship table, and selecting that profile as the target profile. Here, the mapping relationship table is established in advance based on the profile download command and the profile, and the mapping relationship table may be established according to the actual situation, and the embodiments of this disclosure are not specifically limited thereto. The target profile corresponding to the profile download command can be accurately queried from the mapping relationship table, significantly improving the efficiency of downloading the profile.

[0035] In one embodiment, the target profile is written to the eSIM card, the eSIM card is activated, the activation information of the eSIM card is obtained, and based on the activation information, it is determined whether or not the eSIM card has been activated. If it is determined that the eSIM card has been activated and that the SIM card has been inserted, the use of the SIM card is prohibited. If it is determined that the eSIM card has been activated, the use of the SIM card is prohibited, so that the SIM card is simply used for the eSIM card to download the profile, improving the efficiency and accuracy of the eSIM card downloading the profile.

[0036] In one embodiment, a method for determining whether an eSIM card has been activated based on the activation information determines whether the activation information includes a first identifier. If the activation information includes the first identifier, it is determined that the eSIM card has been activated. If the activation information includes a second identifier, it is determined that the eSIM card has not been activated. If the eSIM card has not been activated, the LPA establishes a communication connection with the server using the SIM card's communication network and controls the communication connection to send a command to the server to download the eSIM card profile. By checking whether the eSIM card has been activated, the efficiency and accuracy of activating the eSIM card can be improved.

[0037] As an example, as shown in Figure 3, the process includes S201, when the mobile terminal is powered on; S202, when determining whether the eSIM card has been activated; S203, when determining whether a SIM card has been inserted if the eSIM card has not been activated; S204, when ending the profile download if the eSIM card has been activated; S205, when determining that a SIM card has been inserted, when the SIM card registers with the communication network service; S206, when the SIM card has registered with the communication network service, when the LPA establishes a communication connection with the server using the SIM card's communication network and sends a download command for the eSIM card profile to the server via the communication connection; S207, when obtaining the target profile returned by the server based on the profile download command, writing the target profile to the eSIM card, and activating the eSIM card; S208, when determining whether the eSIM card has been activated; S209, when prohibiting the use of the SIM card if the eSIM card has been activated; and S204, when ending the profile download.

[0038] According to the method for downloading profiles in the above embodiment, if the eSIM card is not activated after the mobile terminal is powered on and a SIM card is inserted, a command to download the eSIM card profile is sent to the server using the SIM card's communication network. The target profile returned by the server based on the profile download command is retrieved, the target profile is written to the eSIM card, and the eSIM card is activated. In this solution, if the eSIM card is not activated, a command to download the eSIM card profile is sent to the server using the SIM card's communication network, solving the problem of the mobile terminal not having a communication network. Furthermore, the target profile returned by the server based on the profile download command is received, the target profile is written to the eSIM card, and the eSIM card is activated. This significantly improves the convenience and accuracy of downloading the target profile for the eSIM card, and also improves the efficiency of activating the eSIM card.
