Fig. 1 is a flowchart illustrating an eSIM card terminal device switching method according to an embodiment of the present invention.

eSIM card terminal device switching can include three phases:

firstly, adding terminal equipment to the terminal equipment. The stage of adding the secondary terminal device to the primary terminal device may be referred to as "the primary terminal device" and "the secondary terminal device" described herein are only used to distinguish the two terminal devices, and the functions of the terminal devices are not limited.

And II, registering the terminal equipment. After the auxiliary terminal device is added to the main terminal device, the auxiliary terminal device needs to be registered in the support system, so that the support system can obtain authentication data and subscription data of the card writing of the auxiliary terminal device.

And thirdly, switching between terminal devices.

The technical scheme of adding the terminal equipment stage to the terminal equipment is introduced firstly based on three stages.

This stage is to add a terminal device (e.g. a secondary terminal device) associated with the terminal device through the terminal device (e.g. a primary terminal device) already registered with the support system. The main terminal device adds the information of the auxiliary terminal device managed under the account to the support system, if the support system does not have the account, the account and the terminal device switching password are set before the auxiliary terminal device is added, and then the information of the auxiliary terminal device is added.

The specific process can comprise the following steps:

s101: the master terminal device receives the add instruction.

S102: the main terminal device obtains identification information of the auxiliary terminal device, such as an International Mobile Equipment Identity (IMEI) of the auxiliary terminal device, an electronic Identity (electronic Identity, eID), and the like.

S103: and the main terminal equipment sends a terminal equipment registration request to the support system according to the received identification information of the auxiliary terminal equipment, wherein the terminal equipment registration request comprises the acquired identification information of the main terminal equipment and the identification information of the auxiliary terminal equipment.

S104: and the support system registers the auxiliary terminal equipment according to the identification information of the main terminal equipment and the identification information of the auxiliary terminal equipment in the received registration request.

S105: and after the support system finishes the registration, the support system sends registration feedback information to the main terminal equipment.

S106: after receiving the registration feedback information including the identification information of the secondary terminal device sent by the support system, the primary terminal device sets an operation password, which may be an operation password associated with the primary terminal device, an operation password associated with the account information, or an operation password associated with the secondary terminal device.

S107: and the main terminal equipment sends the operation password to the support system.

S108: and the support system generates the corresponding relation between the identification information of the auxiliary terminal equipment and the identification information of the main terminal equipment and the corresponding relation between the operation password and the auxiliary terminal equipment according to the received operation password.

After the main terminal device finishes adding the auxiliary terminal device, the support system needs to register the auxiliary terminal device, namely, the auxiliary terminal device registration stage.

The specific process can comprise the following steps:

s201: the auxiliary terminal Equipment receives a registration instruction, the registration instruction comprises identification information of the auxiliary terminal Equipment, and the identification information of the auxiliary terminal Equipment comprises information such as an International Mobile Equipment Identity (IMEI), an electronic Identity (eID) and the like.

S202: and the auxiliary terminal equipment sends an authentication request to the support system after receiving the registration instruction, wherein the authentication request comprises the identification information of the auxiliary terminal equipment.

S203: and after receiving the authentication request sent by the auxiliary terminal equipment, the support system authenticates and authenticates the auxiliary terminal equipment according to the identification information of the auxiliary terminal equipment.

S204: and after finishing the authentication and authorization of the auxiliary terminal equipment, the supporting system sends authentication feedback information to the auxiliary terminal equipment, wherein the authentication feedback information comprises the identification information of the auxiliary terminal equipment.

S205: and after receiving the authentication feedback information sent by the support system, the auxiliary terminal equipment sends an authentication data request to a subscription relationship management data preparation platform SM-DP +, wherein the authentication data request comprises identification information of the auxiliary terminal equipment.

S206: and the SM-DP + authenticates the secondary terminal equipment according to the identification information of the secondary terminal equipment in the authentication data request (for example, the SM-DP + verifies the legality of the eSIM card in the secondary terminal equipment).

S207: when the SM-DP + passes the verification, authentication data is generated, where the authentication data may include SM-DP + packing data such as International Mobile Subscriber Identity (IMSI), authentication Key (K), source signaling point code (Opc), and the like of the secondary terminal device into an operator profile (profile) file.

S208: and the SM-DP + sends the authentication data to the secondary terminal equipment.

S209: an embedded universal integrated circuit card (eUICC) in the secondary terminal device writes the received authentication data into an embedded subscriber identity Module (eSIM) to complete card writing.

S207: and after the secondary terminal equipment finishes card writing, sending card writing data to the SM-DP +.

S208: and the SM-DP + generates card writing result feedback information according to the card writing data received from the auxiliary terminal equipment and sends the card writing result feedback information to the support system, wherein the card writing result feedback information comprises the card writing data and the authentication data.

S209: the support system stores the authentication data in the card writing result feedback information to a subscription database.

After the auxiliary terminal equipment completes registration, the subscription database in the support system already stores the authentication data of at least one auxiliary terminal equipment, and the main terminal equipment establishes a corresponding relationship with at least one auxiliary terminal equipment, so that the condition of terminal equipment switching can be met, and the switching between the terminal equipment is supported, namely, the switching stage between the terminal equipment.

The switching stage between the terminal devices is divided into a switching command initiated by the main terminal device and a switching command initiated by the auxiliary terminal device.

Taking the example of the master terminal device initiating the switching instruction first,

the specific process can comprise the following steps:

s301: the main terminal equipment receives a switching instruction, wherein the switching instruction comprises identification information (including a switching password corresponding to the target terminal equipment to be switched, and an International Mobile Equipment Identity (IMEI) and an international electronic identity (eID) of the target terminal equipment to be switched (any registered auxiliary terminal equipment)).

S302: and the main terminal equipment sends the switching instruction to the support system.

S303: and after receiving the switching instruction, the support system verifies the identification information of the target terminal equipment to be switched, which is included in the switching instruction.

S304: and after the verification of the support system is passed, acquiring authentication data corresponding to the eSIM card of the target terminal equipment from the subscription database according to the identification information of the target terminal equipment to be switched in the switching instruction.

S305: the support system sends the acquired update instruction including the authentication data to a Home Subscriber Server (HSS).

Taking the example of the secondary terminal device initiating the switching instruction,

s401: the auxiliary terminal device receives a switching instruction, where the switching instruction includes identification information (including a switching password corresponding to the target terminal device to be switched, and an IMEI and an eID of the target terminal device to be switched) of a target terminal device to be switched (which may be the main terminal device or any other registered auxiliary terminal device).

S402: and the auxiliary terminal equipment sends the switching instruction to the support system.

S403: and after receiving the switching instruction, the support system verifies the identification information of the target terminal equipment to be switched, which is included in the switching instruction.

S404: and after the verification of the support system is passed, acquiring authentication data corresponding to the eSIM card of the target terminal equipment from the subscription database according to the identification information of the target terminal equipment to be switched in the switching instruction.

S405: the support system sends the acquired update instruction including the authentication data to a Home Subscriber Server (HSS).

S406: and the HSS deletes the authentication data of the original terminal equipment according to the received updating instruction, creates the authentication data corresponding to the eSIM card of the target terminal equipment according to the authentication data corresponding to the eSIM card of the target terminal equipment in the updating instruction, and activates the network function of the target terminal equipment.

In addition, the network used in the present invention may also include a 5G network, and in order to complete the fast switching requirement of the master Mobile phone and the slave Mobile phone, the user number may be used as an account, and the master terminal device and the n slave terminal devices may be registered under each account to manage the authentication data corresponding to the eSIM cards in all the terminal devices of the user, and the identification information of the terminal device includes the terminal device model, the International Mobile Equipment Identity (IMEI), the eID number of the eSIM card of the terminal device, the terminal device operation password, and the like, and the authentication data such as the International Mobile Subscriber Identity (IMSI), the authentication Key (K), the source point code (Original point code, Opc) written in each eSIM card.

the main terminal equipment and the auxiliary terminal equipment comprise an application program, a processor, an eUICC and an eSIM card.

The support system comprises a terminal device signing database.

Fig. 3 shows an application menu interface of the terminal device. The program menu provides three function keys: adding terminal equipment, registering the terminal equipment and switching the terminal equipment.

Adding a terminal device: the method is used for adding terminal equipment information managed under an account into a support system by the main terminal equipment, so that the support system records the corresponding relation between the identification information of the auxiliary terminal equipment and the identification information of the main terminal equipment and the corresponding relation between the operation password and the auxiliary terminal equipment. If the support system has no account, the account and the terminal equipment switching password and the like need to be set firstly when the terminal equipment is added, and then the identification information of the auxiliary terminal equipment is added.

Registering the terminal equipment: the added account, the identification information of the auxiliary terminal equipment and the switching password of the auxiliary terminal equipment are used on the auxiliary terminal equipment to log in a supporting system, and the supporting system issues the use number and the number use permission of the auxiliary terminal equipment corresponding to the account after verifying the identity and the identification information of the auxiliary terminal equipment; then the secondary terminal equipment uses the number, eID of the eSIM card and the like to apply for card writing data to an eSIM card writing platform SM-DP +, and after the application is successful, the secondary terminal equipment writes the eSIM card through the eUICC according to the received card writing data; after the card writing is successful, the SM-DP + feeds back the card writing result to the support system; the support system registers the authentication data such as IMSI, K, Opc and the like written in the eSIM card in a signing database; namely, the terminal equipment registration not only completes the card writing of the eSIM card, but also provides the terminal equipment registration function.

Switching the terminal equipment: the function can be operated on the main terminal equipment or the auxiliary terminal equipment, when the main terminal equipment is operated, a user initiates an application for using the auxiliary terminal equipment through a client, after the support system verifies the identity and the identification information of the terminal equipment, an authentication data updating instruction is issued to an HSS (home subscriber server) at a network side, the HSS deletes the authentication data of an original number and creates the authentication data of the auxiliary terminal equipment according to the authentication data of the auxiliary terminal equipment in the authentication data updating instruction, so that the network function of the auxiliary terminal equipment is activated, and the aim of switching the terminal equipment is fulfilled.

Taking the example of adding a terminal device as an example,

opening an operation interface of terminal equipment, wherein the terminal equipment can be a mobile phone or other wearable equipment provided with a client, the terminal equipment can be an intelligent main terminal equipment or an auxiliary terminal equipment provided with an eSIM card, and also can be other intelligent terminal equipment not provided with the eSIM card (such as iPad with a WIFI connection function and other intelligent terminal equipment not provided with the eSIM card), clicking a menu of 'adding terminal equipment' in the client interface, and inputting identification information of the auxiliary terminal equipment such as IMEI (international mobile equipment identity) and eSIM card eID (electronic identity) numbers of the auxiliary terminal equipment after entering a page.

Optionally, after entering the interface, an information collector (e.g., a camera) of the terminal device may further be used to collect picture identification data (a two-dimensional code, a dynamic code, or the like) of the secondary terminal device, where the picture identification data may include identification information of the secondary terminal device, such as an IMEI, an eSIM card eID number, of the terminal device.

The method comprises the steps that after the terminal equipment acquires identification information of the auxiliary terminal equipment, equipment registration requests are sent to a supporting system, the supporting system receives the registration requests and sends confirmation information to the terminal equipment, then the terminal equipment sets an operation password of the auxiliary terminal equipment and sends the operation password to the supporting system, and the supporting system generates the corresponding relation between the identification information of the auxiliary terminal equipment and the identification information of the main terminal equipment and the corresponding relation between the operation password and the auxiliary terminal equipment according to the operation password.

And then, the support system sends equipment adding result feedback information to the terminal equipment to complete the addition of the terminal equipment by the support system.
