Embedded subscriber identity module (eSIM, embedded subscriber identity module) is the evolution form of SIM, which is directly integrated in the electronic device in the form of a chip. After purchasing the electronic device, the user can directly use the eSIM to communicate between the electronic device and other devices. There is no need to insert a physical physical SIM anymore.

Since the eSIM is integrated inside the electronic device, after the electronic device leaves the factory, there is generally no contract data (Profile) between the user and the operator inside the eSIM. For electronic devices with built-in eSIM, after the user turns on the device, the profile needs to be downloaded online to the eSIM of the electronic device, and then the built-in eSIM of the electronic device can work normally. For an electronic device with a display screen that is convenient for the user to perform interface operations, the user can complete the profile download through an interface operation on the electronic device, while for an electronic device that does not have a display screen or has a small display screen, the user's interface operations are limited, such as For wearable devices or simple Internet of Things (IOT, internet of things) devices, due to limited interface operations, users cannot download Profiles through interface operations on the electronic device body, making it difficult to download Profiles. The solution of downloading subscription data (Profile) by an electronic device from an operator in the prior art is introduced as follows.

Referring to FIG. 1 , it is a system framework and a schematic flow diagram of the Profile downloading process of electronic devices such as mobile phones and tablet computers (PAD, portable android device) that have display screens and are convenient for users to perform interface operations. It mainly includes: the user signs a contract with the operator through the operator's store or the operator's App; the operator's server generates a Profile, and stores the Profile to instruct the subscription manager data preparation plus (SM-DP+, subscription manager data preparation plus), and the operation The merchant server generates the activation code corresponding to the above Profile, and transmits the activation code to the electronic device. The activation code contains the address of SM-DP+, and the above SM-DP+ is a server for supporting Profile download; the electronic device recognizes the SM from the activation code. -DP+ address, send a Profile download request to SM-DP+; SM-DP+ starts Profile data download after receiving the Profile download request. Through the above process, the electronic device can download the Profile into the eSIM of the electronic device.

See Figure 2, which is a system framework and flow diagram of the Profile download process for electronic devices such as wearable devices and IOT devices with limited interface operations. Compared with the process shown in Figure 1, auxiliary equipment is added, here Auxiliary devices are generally mobile phones, PADs and other electronic devices with display screens that are convenient for users to perform interface operations. It mainly includes: the user signs a contract with the operator through the operator's store or the operator's App; the operator's server generates a Profile and stores the Profile in SM-DP+, and the operator's server generates the activation code corresponding to the above Profile, and the activation code Transmission to the auxiliary device; the auxiliary device transmits the activation code to the main device through Bluetooth, where the main device is the above-mentioned wearable device, IOT device and other electronic devices with limited user interface operations; the main device recognizes the activation code from the activation code. SM-DP+ address, send a Profile download request to SM-DP+; SM-DP+ starts Profile data download after receiving the Profile download request. Through the above process, the main device can download the profile to the eSIM of the main device. It should be noted that the data transmission between the main device and SM-DP+ is forwarded by the auxiliary device, that is: the main device sends a Profile download request to the auxiliary device, and the auxiliary device forwards the Profile download request to the SM-DP+, the same , SM-DP+ sends the Profile to the auxiliary device, and the auxiliary device forwards the Profile to the main device via Bluetooth.

In the Profile download method in the prior art, for electronic devices such as wearable devices and IOT devices, especially IOT devices, for which the user has limited interface operations, in order to obtain the activation code and Profile from the auxiliary device, the user must first operate the Bluetooth pairing and connection between electronic devices and auxiliary devices, if faced with a large number of IOT devices, users have to perform repeated Bluetooth pairing and connection operations for each IOT device, the process is cumbersome and time-consuming; moreover, in order to be able to When the activation code and profile are transmitted between the device and the auxiliary device, the speed requirement is met. The electronic device must have a built-in traditional Bluetooth module instead of a built-in BLE, which will lead to an increase in the cost and power consumption of the electronic device. If the main business of the electronic device does not have an application scenario for Bluetooth , It also leads to the waste of the built-in bluetooth module in the electronic equipment.

It should be noted that if the electronic device is turned on, after a round of carrier network search within a preset period of time, the contracted second carrier network is not searched, and a process similar to failed attempt 1 and failed attempt 2 is executed. , then, after performing a round of operator network search, the electronic device can perform regular operator network search in a certain period until step 805c to step 810c are executed to complete the profile download and use the second operator network for communication .

It should be noted that, in Figure 8, the user signs an electronic device at one operator as an example. Optionally, the user can also go to two or more operators to sign an electronic device, but the signed operator is generally Table 1 records the operator with the operator network identifier, so that the electronic device can find the corresponding download server address through Table 1, and download the Profile. If the user signs contracts with two or more operators, the electronic device can first download the profile from the download server of which operator, and use which operator's network to communicate. After signing the contract for the electronic device, assuming that the electronic device first searches the network of the first operator and downloads the profile from the first download server of the first operator, the electronic device can then use the network of the first operator to communicate .

It should be noted that the embodiment shown in FIG. 8 may be applicable to the following scenarios:

The electronic device manufacturer produces electronic devices that are common to at least two operators, and presets the corresponding relationship between the network identification of at least two operators and the download server address in the electronic device, and the operator recorded in the corresponding relationship preset by the user in the electronic device Operators who decide to sign on their own. For example, assuming that the corresponding relationship shown in Table 1 is preset in the electronic device, the user can select one or more operators from the first operator to the third operator to sign. or,

When an electronic equipment manufacturer produces electronic equipment dedicated to a certain operator, such as electronic equipment dedicated to a second operator, the electronic equipment may preset the network identifier of the second operator and the download server address of the second operator (for example, Table 1 According to the corresponding relationship between the download server address B) in , the user can only go to the second operator to sign a contract for the electronic device.

In the embodiment shown in FIG. 8 , the corresponding relationship between the network identifier of the operator and the address of the download server is built into the electronic device, and the address of the download server is intelligently matched through the network identifier of the operator analyzed during the network search process. In the technical solution shown in Figure 1 and Figure 2, the activation code in the signing process must be relied on to obtain the download server address, and pass it to the main device through the auxiliary device (for the IOT device scenario), and in the technical solution shown in Figure 3 and Figure 4 It must rely on the SM-DS server to obtain the address of the download server, which can neither rely on the delivery of auxiliary equipment nor rely on the newly added SM-DS server on the network side; moreover, as long as the user completes the contract on the operator's server, the user can Start the electronic device at any time, and the electronic device will complete the actions of profile download and network access by itself, without the user's operation, which simplifies the user's experience of downloading the profile. In particular, for enterprise users and other scenarios that need to download profiles for a large number of IOT devices, it is completely possible to download and use profiles automatically when electronic devices are turned on without manual intervention, which greatly reduces labor costs.

Moreover, the method for downloading contract data in the embodiment of the present application, for wearable devices and IOT devices and other electronic devices with limited user interface operations, especially IOT devices, does not need to have a built-in traditional Bluetooth module, and does not need to perform Bluetooth pairing and connection with auxiliary devices. There is no need to perform data interaction with auxiliary equipment, which simplifies the download process of Profile, and also simplifies the download process of Profile for electronic devices such as mobile phones and PADs with unlimited user interface operations; moreover, compared to Figure 3 and Figure 3 In the example shown in 4, there is no need to build an additional SM-DS server, which effectively reduces the complexity of the Profile download operation, and reduces the operating costs of electronic equipment and operators.

In combination with the system architecture and data interaction relationship shown in FIG. 7 , the method for downloading subscription data in this embodiment of the present application will be described through the embodiment shown in FIG. 9 . Different from the situation in Figure 8 where the user selects an operator to sign a contract based on the corresponding relationship between the built-in operator network identifier and the download server address of the purchased electronic device, in the embodiment shown in Figure 9, before the electronic equipment manufacturer produces the electronic equipment, A user such as an enterprise has signed a contract with a target operator and requires the electronic equipment manufacturer to customize the electronic equipment for the target operator; or, the operator may also require the electronic equipment manufacturer to customize the electronic equipment for the operator. In FIG. 9 , it is assumed that the target operator signed by the electronic device is the second operator. In the embodiment shown in FIG. 9 , the corresponding relationship between the target operator's network identifier and the target operator's download server address, that is, the target download server address, is built into the electronic device. In FIG. 9, taking the target operator as an example of the second operator, correspondingly, the network identifier of the target operator is the network identifier of the second operator, the target download server is the second download server, and the address of the target download server is the second download server address.

Referring to Fig. 9, this embodiment includes three phases, which are the signing phase, the production phase and the downloading phase. specific:

In the signing stage, the following steps 901-902 are included:

Step 901: The user obtains the identification information of the built-in eSIM of the electronic device that needs to be subscribed, uploads the obtained identification information to the server of the second operator (that is, the server of the target operator), and executes the signing process on the server of the second operator .

Step 902: The second operator server generates a Profile according to the identification information uploaded by the user, and stores the Profile in the second download server (ie, the target download server).

In the production stage, the following steps 903-904 are included:

Step 903: The user submits the identification information of the eSIM built in the electronic device to the electronic device manufacturer, or the user directly purchases an eSIM card with signed identification information from the eSIM card manufacturer and hands it to the electronic device manufacturer;

Step 904: The electronic device manufacturer produces the electronic device according to the identification information of the eSIM provided by the user or the eSIM card delivered by the user, and configures the electronic device to only search for the network identification of the target operator after starting up.

The target operator's network identifier in FIG. 9 is the second operator's network identifier, which is assumed to be PLMN B.

In the profile download stage, the following steps 905-911 are included:

Step 905: The electronic device is turned on.

After the electronic device is turned on, search for the second operator network (that is, the target operator network), and the electronic device can have a built-in second operator network identifier (that is, the target operator network identifier), and the electronic device searches the operator network. In the process, it is judged whether the operator network identifier of the searched operator network is consistent with the built-in second operator network identifier. If they are consistent, the network search is successful, otherwise the network search fails. Based on the success and failure of searching the Internet, the steps that the electronic device may execute after starting up are described respectively:

Failed attempt 1:

Step 906a: the electronic device searches for the second operator's network (that is, the target operator's network).

Step 907a: If the electronic device does not find the operator's network, or the searched operator's network ID is inconsistent with the second operator's network ID (that is, the target operator's network ID) built into the electronic device, the electronic device searches for the second operator's network ID If the network fails, start a periodic retry; the above-mentioned periodic retry means that the electronic device re-searches the network of the second operator based on a certain preset period or a certain specified time, and the above-mentioned preset period or specified time is not limited by the embodiment of this application .

Successful attempts:

Step 906b: The electronic device searches for the second operator network (that is, the target operator network).

Step 907b: The electronic device searches for the second operator's network, obtains the operator's network identifier in the broadcast message, determines that it is consistent with the second operator's network identifier (that is, the target operator's network identifier) built into the electronic device, and searches for the second operator's network identifier. The second operator's network (that is, the target operator's network) succeeds.

Step 908b: The electronic device finds the second download server address (that is, the target download server address) corresponding to the network identifier of the second operator;

Step 909b: The electronic device accesses the second download server according to the address of the second download server, and sends a Profile download request to the second download server, and the request carries the identification information of the built-in eSIM of the electronic device;

Step 910b: The electronic device receives the Profile request success message fed back by the first download server, and downloads the Profile from the first download server to the built-in eSIM.

Step 911b: The electronic device communicates using the second operator's network based on the downloaded Profile.

In the embodiment shown in Figure 9, the user can complete the contract with the operator before the electronic device is produced, and specify the target operator network for the electronic device to search. After the manufacturer delivers the electronic device and the user turns on the electronic device, the electronic The device can immediately search the network of the target operator, download and use the Profile, and further simplify the experience of using the electronic device; compared with the embodiment shown in Figure 8, it can further simplify the multiple attempts of the electronic device to find other profiles in the embodiment shown in Figure 8. The process of downloading the server address corresponding to the network of the non-target operator reduces the time for the electronic device to download the Profile.

It should be noted that, in the embodiment shown in FIG. 9 , taking the preset corresponding relationship between the network identifier of the target operator and the target download server in the electronic device, the electronic device executes step 908b to obtain the address of the target download server as an example. Optionally, the corresponding relationship between the network identifier of the target operator and the target download server may not be preset in the electronic device, and only the address of the target download server is preset. Correspondingly, after the electronic device executes step 907b, it directly executes step 909b, according to The preset target download server address can be used to access the target download server.

It should be noted that in FIG. 9, the target operator network is an example of an operator network. Optionally, the target operator network in FIG. 9 may also be extended to two or more operator networks. Correspondingly, the electronic device The corresponding relationship between the network identifier of each target operator and the address of the download server is preset in the network, and when the electronic device searches the network of the target operator, it judges whether the network identifier of the searched operator network is consistent with the preset target operator network. One of the target operator network identifiers in the identification is consistent. If they are consistent, the corresponding download server address is found from the preset correspondence between each target operator network identifier and the download server address, and the Profile is downloaded.
