Description

Subscription data downloading method and electronic equipment

Technical Field

The present application relates to the field of intelligent terminal technologies, and in particular, to a subscription data downloading method and an electronic device.

Background

An embedded subscriber identity module (eSIM) is an evolved form of a SIM, and is directly integrated in an electronic device in the form of a chip, and a user can directly use the eSIM to communicate the electronic device with other devices after purchasing the electronic device without inserting a physical entity SIM.

Since the eSIM is integrated inside the electronic device, after the electronic device leaves a factory, the eSIM is generally free of any subscription data (Profile) between the user and the operator. After a user starts up, the electronic device with the built-in eSIM needs to download a Profile to the eSIM of the electronic device on line, and then the eSIM built in the electronic device can work normally. For an electronic device which is provided with a display screen and facilitates interface operation of a user, the user can complete Profile downloading through interface operation on the electronic device, and for an electronic device which is not provided with a display screen or has a small display screen and therefore interface operation of the user is limited, such as a wearable device or an internet of things (IOT) device with a simple form, because interface operation is limited, the user cannot download the Profile through interface operation on an electronic device body, so that the Profile downloading is difficult. A scheme for downloading subscription data (Profile) from an operator for an electronic device in the prior art is described as follows.

Fig. 1 shows a system framework and a flow diagram of a Profile downloading process of an electronic device such as a mobile phone and a tablet computer (PAD) that has a display screen and facilitates interface operations of a user. The method mainly comprises the following steps: the user signs a contract with the operator through an operator store or an operator App; the method comprises the steps that an operator server generates a Profile, stores the Profile into an SM-DP (SM-DP + subscription manager data preparation plus) indicating subscription manager data preparation, generates an activation code corresponding to the Profile, and transmits the activation code to electronic equipment, wherein the activation code comprises an SM-DP + address, and the SM-DP + is a server for supporting downloading of the Profile; the electronic equipment identifies the SM-DP + address from the activation code and sends a Profile downloading request to the SM-DP +; and after the SM-DP + receives the Profile downloading request, starting the Profile data downloading. Through the above process, the electronic device can download the Profile into the eSIM of the electronic device.

Referring to fig. 2, a system framework and a flow diagram of a Profile downloading process of an electronic device with limited interface operation performed by a user, such as a wearable device or an IOT device, are shown, and an auxiliary device is added in comparison with the flow shown in fig. 1, where the auxiliary device is generally an electronic device with a display screen, such as a mobile phone or a PAD, and is convenient for the user to perform interface operation. The method mainly comprises the following steps: the user signs a contract with the operator through an operator store or an operator App; the operator service side generates a Profile, stores the Profile to SM-DP +, generates an activation code corresponding to the Profile and transmits the activation code to the auxiliary equipment; the auxiliary equipment transmits the activation code to the main equipment through Bluetooth, wherein the main equipment is electronic equipment with limited interface operation performed by users such as the wearable equipment and the IOT equipment; the master equipment identifies an SM-DP + address from the activation code and sends a Profile downloading request to the SM-DP +; and after the SM-DP + receives the Profile downloading request, starting the Profile data downloading. Through the above process, the master device can download the Profile into the eSIM of the master device. It should be noted that, the data transmission between the master device and the SM-DP + is forwarded through the auxiliary device, that is: the method comprises the steps that the main equipment sends a Profile downloading request to the auxiliary equipment, the auxiliary equipment forwards the Profile downloading request to the SM-DP +, and similarly, the SM-DP + sends a Profile to the auxiliary equipment, and the auxiliary equipment forwards the Profile to the main equipment through Bluetooth.

In the prior art, for electronic devices with limited interface operations, such as wearable devices and IOT devices, especially IOT devices, in order to acquire an activation code and a Profile from an auxiliary device, a user must first operate the electronic device and the auxiliary device to perform bluetooth pairing and connection before downloading the Profile, and if facing a large amount of IOT devices, the user needs to perform repeated bluetooth pairing and connection operations on each IOT device, which is tedious in process and consumes too much time; moreover, in order to meet the rate requirement when the activation code and the Profile are transmitted between the electronic device and the auxiliary device, the electronic device must be internally provided with a conventional bluetooth module, but cannot be internally provided with BLE, which causes the cost and power consumption of the electronic device to increase, and if the main service of the electronic device has no application scene to bluetooth, the waste of the bluetooth module internally arranged in the electronic device is also caused.

In order to solve the problems that in the prior art, cost and power consumption are high due to the fact that a Bluetooth module is arranged in electronic equipment with limited user interface operation, particularly IOT equipment, and the process of downloading the Profile by the electronic equipment is complicated, in one embodiment of the application, a more automatic process is introduced, namely, an SM-DS server is used for assisting the electronic equipment in downloading the Profile, and the electronic equipment can acquire an SM-DP + address in a mode that downloading events are registered on the SM-DS server and the electronic equipment is regularly inquired. Specifically, the method comprises the following steps:

fig. 3 shows a system framework and a flow diagram of a Profile downloading process of an electronic device, such as a mobile phone and a PAD, which has a display screen and facilitates interface operations of a user. The method mainly comprises the following steps:

The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into image signal in standard RGB, YUV and other formats. In some embodiments, the electronic device 500 may include 1 or N cameras 593, N being a positive integer greater than 1.

In this way, the electronic device 500 may play or record video in a variety of encoding formats, such as: moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, and the like.

The NPU is a neural-network (NN) computing processor that processes input information quickly by using a biological neural network structure, for example, by using a transfer mode between neurons of a human brain, and can also learn by itself continuously. Applications such as intelligent recognition of the electronic device 500 can be realized through the NPU, for example: image recognition, face recognition, speech recognition, text understanding, and the like.

The external memory interface 520 may be used to connect an external memory card, such as a Micro SD card, to extend the memory capability of the electronic device 500. The external memory card communicates with the processor 510 through the external memory interface 520 to implement a data storage function.

The electronic device may have a data service access capability after being started, where the data service access capability may be a wireless fidelity (WiFi) access, or a data service solution such as Profile (provisioning Profile) with a capability limit preset in an eSIM built in the electronic device.

Referring to fig. 7, assuming that a user signs a contract (also referred to as an account opening) at a first operator service end based on identification information of an eSIM built in an electronic device, for example, an EID, the first operator service end generates a corresponding Profile based on the identification information of the eSIM, and sends the Profile to a first download server for storage, and the electronic device may access the first download server based on an address of the first download server and download the Profile based on the identification information of the eSIM. The identification information of the eSIM is used to identify the eSIM.

Similarly, assuming that the user has completed signing (also referred to as opening an account) at the second operator service end based on the identification information of the eSIM built in the electronic device, for example, the EID, the second operator service end generates a corresponding Profile based on the identification information of the eSIM, and sends the Profile to the second download server for storage, and the electronic device can access the second download server based on the address of the second download server and download the Profile based on the identification information of the eSIM.

Unlike the electronic device in fig. 1-2 that obtains the SM-DP + address from the operator server and the electronic device in fig. 3-4 that obtains the SM-DP + address from the SM-DS server, the electronic device shown in fig. 7 stores a corresponding relationship between at least one operator network identifier and a download server address.

It should be noted that, in table 1, the correspondence between 3 operator network identifiers and download server addresses stored in the electronic device is taken as an example, in an actual application, the number of the correspondence stored in table 1 may be more or less, and the embodiment of the present application is not limited.

TABLE 1

In the technical solutions shown in fig. 1-2, the address of the download server of the operator is carried in the activation code and transmitted to the electronic device that needs to download the Profile, such as a mobile phone, a PAD, a wearable device, an IOT device, etc.; in the technical solutions shown in fig. 3 to 4, the address of the download server of the operator is stored in the SM-DS server, and the electronic device needs to first obtain the address of the download server of the signed operator from the SM-DS server, and then can access the download server based on the obtained address of the download server, so as to implement downloading of the Profile; in the embodiment of the present application shown in fig. 7, the address of the download server of at least one operator is stored in the electronic device, so that the electronic device does not need to obtain the address of the download server through bluetooth, data communication, and the like, thereby reducing data interaction between the electronic device and other devices based on the address of the download server.

With reference to the system architecture and the data interaction relationship shown in fig. 7, a description is given to the subscription data downloading method in the embodiment of the present application by using the embodiment shown in fig. 8. In the embodiment shown in fig. 8, the correspondence relationship shown in table 1 is preset in the electronic device, and the user selects the second operator to sign a subscription. The subscription data downloading method of the embodiment shown in fig. 8 may be divided into two stages, which are respectively: a subscription phase and a download phase.

In the signing stage, the method comprises the following steps 801-803:

step 801: the user acquires the identification information of the eSIM built in the electronic equipment needing to be signed.

Specifically, the user may sign a contract with the operator at any time after purchasing the electronic device based on the identification information of the eSIM built in the electronic device, that is, an account is opened at the operator, and the signing route may be that the user goes to an operator store to complete a signing process, or the user uses the auxiliary device to access a webpage of the operator, an APP of the operator, and the like to execute the signing process. It should be noted that, if the electronic device to be signed is an electronic device which has a display screen and facilitates user interface operation, the auxiliary device may be an electronic device to be signed or another electronic device, and if the electronic device to be signed is an electronic device whose user interface operation is limited, the auxiliary device may be an electronic device other than the electronic device to be signed.

Before signing up, a user can obtain identification information of an eSIM built in an electronic device through an auxiliary device, wherein the identification information is used for uniquely identifying the eSIM, and optionally, the identification information can be an EID of the eSIM. The user can acquire the identification information of the eSIM of the electronic device in a manual input mode, a two-dimensional code scanning mode, and the like. When a user needs to sign up for a large number of electronic devices at a time, the user may also provide, by a provider (e.g., a vendor or a manufacturer) of the electronic devices to be signed up, identification information, such as an EID, of the electronic device embedded esims to be signed up by the user in a batch at a time.

Step 802: and the user uploads the acquired identification information of the eSIM built in the electronic equipment to a target operator server, and the signing process is completed at the target operator server.

The target operator server is an operator server of an operator (hereinafter, referred to as a target operator) selected by the user from a plurality of operators and desiring to perform a subscription, for example, in fig. 8, the second operator is the target operator, and the second operator server is the target operator server.

Step 803: and the target operator service terminal generates a Profile according to the identification information of the eSIM uploaded by the user, and stores the Profile in the target download server.

It should be noted that the Profile may also be generated by the target download server according to the identification information of the eSIM, and the embodiment of the present application is not limited.

The target download server refers to a server storing the Profile of the electronic device, that is, a server provided by the target operator for downloading the Profile, and in fig. 8, the second download server is the Profile download target server.

In the Profile downloading stage, the method comprises the following steps 804 to 810:

step 804: the electronic device is powered on.

It should be noted that, in the embodiment shown in fig. 8, before the electronic device is turned on, the user preferably has finished signing for the electronic device at least one operator, that is, step 804 is preferably executed after step 803, otherwise, if the electronic device has not signed up at the time of turning on, the electronic device cannot download the Profile, and the electronic device may not download the Profile until step 803 is executed.

After the electronic device is powered on, the operator network search may be performed, and in fig. 8, the following possible Profile downloading flows are taken as examples to describe steps that may be executed after the electronic device is powered on, and the following corresponding relationships shown in table 1 are preset in the electronic device as an example.

Failed attempt 1:

step 805 a: the electronic device performs an operator network search.

In the embodiment of the present application, the electronic device performs the operator network search generally based on a baseband chip built in the electronic device. The baseband chip may correspond to the baseband processor described in fig. 5.

Step 806 a: the electronic device searches for a fourth operator network and obtains a fourth operator network identifier, such as PLMN D, in the broadcast message of the fourth operator network.

Referring to fig. 8, taking an example that the electronic device receives a broadcast message transmitted by a fourth base station that is provided with a communication service by a fourth operator, the fourth base station is not shown in fig. 7.

Step 807 a: the electronic device searches for the address of the download server corresponding to the operator network identifier PLMN D from the preset correspondence (i.e. table 1) between the operator network identifier and the address of the download server, and if the corresponding address of the download server is not found, the branch flow is ended.

Since the download server address corresponding to the fourth operator network identifier PLMN D is not stored in table 1, the electronic device cannot find the corresponding download server address, and the Profile download attempt fails.

Failed attempt 2:

step 805 b: the electronic device performs an operator network search.

Step 806 b: the electronic equipment searches the first operator network and acquires a first operator network identifier PLMN A in a broadcast message of the first operator network.

Referring to fig. 8, an example is given in which the electronic device receives a broadcast message sent by the first base station.

Step 807 b: the electronic device searches for the download server address corresponding to the first operator network identifier PLMN a from the preset correspondence (also referred to as table 1) between the operator network identifiers and the download server addresses, and obtains the download server address a.

Step 808 b: the electronic equipment accesses a first download server according to the address A of the download server, and sends a Profile download request to the first download server, wherein the request carries identification information of an eSIM (embedded subscriber identity module) in the electronic equipment;

step 809 b: and the electronic equipment receives the Profile request failure message fed back by the first downloading server.

Because the user does not sign a contract at the first operator service end, the Profile corresponding to the identification information of the electronic equipment built-in eSIM is not stored in the first downloading server, the first downloading server feeds back a Profile request failure message to the electronic equipment, and the Profile downloading attempt fails.

Successful attempts were:

step 805 c: the electronic device performs an operator network search.

Step 806 c: the electronic equipment searches the second operator network and acquires a second operator network identifier PLMN B in the second operator network broadcast message.

Referring to fig. 8, the electronic device receives the broadcast message sent by the second base station as an example.

Step 807 c: the electronic device searches for the download server address corresponding to the second operator network identifier PLMN B from the preset correspondence (i.e., table 1) between the operator network identifiers and the download server addresses, and obtains the download server address B.

Step 808 c: the electronic equipment accesses a second download server according to the address B of the download server, and sends a Profile download request to the second download server, wherein the request carries the identification information of the eSIM built in the electronic equipment;

step 809 c: and the electronic equipment receives the Profile request success message fed back by the second download server, and downloads the Profile from the first download server to the built-in eSIM.

Step 810 c: the electronic device communicates using the second carrier network based on the downloaded Profile.

In steps 808b and 808c, the electronic device needs to access the corresponding download server according to the address of the download server, so that the electronic device is required to have a data service access capability after being started, where the data service access capability may be WiFi access, or a data service solution such as profile (provisioning profile) that is preset with capability limitation in an eSIM built in the electronic device, and the embodiment of the present application is not limited. The Profile with the preset capability limit in the eSIM is used for supporting the eSIM to access a download server, and the Profile is downloaded from the download server.

It should be noted that, if after the electronic device is powered on, after a round of operator network search is performed within a preset time period, no second contracted operator network is searched, and flows similar to the failed attempt 1 and the failed attempt 2 are executed, after the electronic device executes the round of operator network search, the electronic device may perform regular operator network search at a certain period until steps 805c to 810c are executed, complete Profile download, and use the second operator network for communication.

It should be noted that, in fig. 8, for example, a user signs an agreement for an electronic device at one operator, optionally, the user may also sign an agreement for the electronic device by going to two or more operators, but the signed operators are generally the operators with the operator network identifiers recorded in table 1, so that the electronic device can find the corresponding download server address through table 1 to perform Profile download. If the user signs up at two or more operators, the electronic device may first download the Profile from the download server of which operator, and then use which operator network for communication, for example, if the user signs up at both the first operator and the second operator for the electronic device, assuming that the electronic device first searches for the first operator network and downloads the Profile from the first download server of the first operator, then the electronic device may later use the first operator network for communication.

It should be noted that the embodiment shown in fig. 8 can be applied to the following scenarios:

an electronic equipment manufacturer produces electronic equipment common to at least two operators, the corresponding relation between the network identifiers of the at least two operators and the address of the download server is preset in the electronic equipment, a user determines the operator to sign a contract among the operators recorded in the corresponding relation preset in the electronic equipment, for example, assuming that the corresponding relation shown in table 1 is preset in the electronic equipment, the user can select one or more operators from a first operator to a third operator to sign a contract. Alternatively, the first and second electrodes may be,

if an electronic device manufacturer produces an electronic device dedicated to a certain operator, for example, an electronic device dedicated to a second operator, a corresponding relationship between a network identifier of the second operator and a download server address (for example, the download server address B in table 1) of the second operator may be preset in the electronic device, and a user may only sign a contract for the electronic device with the second operator.

In the embodiment shown in fig. 8, the corresponding relationship between the operator network identifier and the download server address is built in the electronic device, and the download server address is intelligently matched through the operator network identifier analyzed in the network searching process, and compared with the technical solutions shown in fig. 1 and fig. 2, which must rely on the activation code in the subscription process to obtain the download server address and transmit the download server address to the main device (for the IOT device scenario), and the technical solutions shown in fig. 3 and fig. 4, which must rely on the SM-DS server to obtain the download server address, it is possible to achieve the purpose of not relying on the transmission of the auxiliary device, nor on the SM-DS server newly added on the network side; and as long as the user finishes signing at the service end of the operator, the user starts the electronic equipment at any time, and the electronic equipment can finish the actions of Profile downloading and network accessing by itself, so that the user does not need to operate, and the experience of downloading the Profile by the user is simplified. Particularly, for the scenes that enterprise users and the like need to download the Profile for massive IOT equipment, the downloading and the use of the Profile can be automatically completed when the electronic equipment is started without manual intervention, and the labor cost is greatly reduced.

Moreover, the method for downloading subscription data in the embodiment of the application simplifies the downloading flow of the Profile for the electronic devices with limited user interface operation, such as wearable devices and IOT devices, in particular to the IOT devices, without a built-in traditional bluetooth module, without bluetooth pairing and connection with the auxiliary devices, and without data interaction with the auxiliary devices, and also simplifies the downloading flow of the Profile for the electronic devices with unlimited user interface operation, such as mobile phones and PADs; moreover, compared with the examples shown in fig. 3 and 4, an SM-DS server does not need to be additionally built, so that the complexity of Profile downloading operation is effectively reduced, and the operation cost of electronic equipment and operators is reduced.

With reference to the system architecture and the data interaction relationship shown in fig. 7, a description is given to the subscription data downloading method in the embodiment of the present application by using the embodiment shown in fig. 9. In contrast to the situation that the user selects an operator to sign a contract based on the corresponding relationship between the purchased network identifier of the electronic device built-in operator and the address of the download server in fig. 8, in the embodiment shown in fig. 9, before the electronic device manufacturer produces the electronic device, the user, for example, a certain enterprise, has signed a contract with the target operator and requests the electronic device manufacturer to customize the electronic device for the target operator; alternatively, the operator may require the electronic device manufacturer to customize the electronic device for the operator. It is assumed in fig. 9 that the target operator to which the electronic device has contracted is the second operator. In the embodiment shown in fig. 9, the electronic device is provided with a corresponding relationship between a network identifier of a target operator and an address of a download server of the target operator, that is, an address of the target download server. In fig. 9, taking the target operator as the second operator as an example, correspondingly, the target operator network identifier is the second operator network identifier, the target download server is the second download server, and the target download server address is the second download server address.

Referring to fig. 9, this embodiment includes three phases, a sign-up phase, a production phase, and a download phase. Specifically, the method comprises the following steps:

in the signing stage, the method comprises the following steps 901-902:

step 901: the user acquires identification information of an eSIM (embedded subscriber identity module) built in the electronic equipment to be signed, uploads the acquired identification information to a second operator service end (namely, a target operator service end), and executes a signing process at the second operator service end.

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

In the production stage, the method comprises the following steps 903-904:

step 903: the user submits the built-in eSIM identification information of the electronic equipment to an electronic equipment manufacturer, or the user directly purchases an eSIM card with signed identification information from an eSIM card manufacturer and delivers the eSIM card to the electronic equipment manufacturer;

step 904: and the electronic equipment manufacturer produces the electronic equipment according to the identification information of the eSIM provided by the user or the eSIM card delivered by the user, and only searches the network identification of the target operator after configuring the electronic equipment to be started.

The target operator network identity in fig. 9 is the second operator network identity, assumed to be PLMN B.

In the Profile downloading stage, the method comprises the following steps 905-911:

step 905: the electronic device is powered on.

After the electronic equipment is started, searching a second operator network (namely a target operator network), wherein a second operator network identifier (namely a target operator network identifier) can be built in the electronic equipment, and the electronic equipment judges whether the searched operator network identifier of the operator network is consistent with the built-in second operator network identifier or not in the operator network searching process, if so, the network searching is successful, otherwise, the network searching is failed. Based on two conditions of success and failure of network searching, the steps possibly executed after the electronic equipment is started are respectively described as follows:

failed attempt 1:

step 906 a: the electronic device conducts a second carrier network (i.e., target carrier network) search.

Step 907 a: if the electronic equipment does not search the operator network, or the searched operator network identifier is inconsistent with a second operator network identifier (namely a target operator network identifier) built in the electronic equipment, the electronic equipment fails to search the second operator network, and starts to retry regularly; the above-mentioned periodic retry refers to that the electronic device re-performs the second operator network search based on a certain preset period or a certain specified time, and the above-mentioned preset period or specified time is not limited in this embodiment of the application.

Successful attempts were:

step 906 b: the electronic device conducts a second carrier network (i.e., target carrier network) search.

Step 907 b: the electronic device searches for a second operator network, acquires the operator network identifier in the broadcast message, judges that the operator network identifier is consistent with a second operator network identifier (namely, a target operator network identifier) built in the electronic device, and successfully searches for the second operator network (namely, the target operator network).

Step 908 b: the electronic equipment finds a second download server address (namely a target download server address) corresponding to the second operator network identifier;

step 909 b: the electronic equipment accesses a second download server according to the address of the second download server, and sends a Profile download request to the second download server, wherein the request carries the identification information of the eSIM built in the electronic equipment;

step 910 b: and the electronic equipment receives the Profile request success message fed back by the first downloading server, and downloads the Profile from the first downloading server to the built-in eSIM.

Step 911 b: the electronic device communicates using the second carrier network based on the downloaded Profile.

In the embodiment shown in fig. 9, the user may complete the subscription with the operator before the electronic device is produced, and designate the target operator network for electronic device search, and after the manufacturer delivers the electronic device and the user powers on the electronic device, the electronic device may immediately search the target operator network, perform Profile download and use, thereby further simplifying the use experience of the electronic device; compared with the embodiment shown in fig. 8, the process that the electronic device tries to find the address of the download server corresponding to the other non-target operator network for multiple times in the embodiment shown in fig. 8 can be further simplified, and the time for downloading the Profile by the electronic device is reduced.

It should be noted that, in the embodiment shown in fig. 9, for example, the electronic device presets the corresponding relationship between the target operator network identifier and the target download server, and the electronic device executes step 908b to acquire the target download server address, optionally, the electronic device may also not preset the corresponding relationship between the target operator network identifier and the target download server, and only presets the target download server address, and accordingly, after executing step 907b, the electronic device directly executes step 909b, and accesses the target download server according to the preset target download server address.

It should be noted that, for example, the target operator network in fig. 9 is one operator network, optionally, the target operator network in fig. 9 may also be extended to 2 or more operator networks, and correspondingly, the electronic device presets a corresponding relationship between each target operator network identifier and a download server address, and when the electronic device performs network search of the target operator, determines whether the searched network identifier of the operator network is consistent with one target operator network identifier in the preset target operator network identifiers, and if so, finds a corresponding download server address from the preset corresponding relationship between each target operator network identifier and the download server address, and performs Profile download, which is not described herein.
