Problems solved by technology

[0005] For the existing two methods, the first method needs to rely on the openmobile interface of the android system because of the need for preset files, so there is a problem that the download mechanism is complicated and cannot be applied to all systems; Transformation, each new device or communication method needs to be redesigned, thus increasing the development cost

Embodiment 1

[0041] figure 2 The structure of an eSIM card is shown, where the eSIM card 110 includes a communication element 210 and a secure element 220, where:

[0042] The communication component 210 establishes a communication channel 150 with the management terminal 120.

[0043] The communication element 210 may implement contact communication or non-contact communication, and the non-contact communication includes an existing wireless communication method, such as Bluetooth communication.

[0044] The secure element 210 executes application-related operating instructions, authentication, and stores communication data of the operator downloaded through the communication channel 150. The secure element 210 is implemented by opening a secure area in the eSIM card, and the secure area must be authenticated before being accessed, and no access interface is provided for ordinary users.

[0045] image 3 The structure of the management terminal 120 is shown. The management terminal 120 includes ...

Embodiment 2

[0052] Attached below Figure 4 Describe the working process of the eSIM card management system. The working method of the eSIM card management system includes the following steps:

[0053] A communication channel 150 is established between the communication element 210 of the eSIM card 110 and the management terminal 120;

[0054] The management terminal 120 requests to obtain card information;

[0055] The communication element 210 obtains the card information stored in the secure element 220, such as the number of the eSIM card;

[0056] The communication element 210 sends the card information to the management terminal 120 through the communication channel 150;

[0057] The management terminal 120 sends the card information to the server 130 through the Internet channel 140;

[0058] The server 130 queries the database through card information and organizes authentication information;

[0059] The server 130 generates authentication information such as the current session ID, eSim ran...

Embodiment 3

[0077] In the third embodiment, the process of downloading the communication data of the operator by the eSIM card is described. The downloaded communication data of the operator needs to be activated externally when it is used. Figure 5 Describe the process of activating one of the communication data of multiple operators on the eSIM card.

[0078] Including the following steps:

[0079] The management terminal 120 organizes activation instructions;

[0080] The management terminal 120 and the communication element 210 establish a communication channel 150;

[0081] Transparently transmit the activation instruction through the communication channel 150;

[0082] After receiving the activation instruction, the secure element 220 obtains the downloaded operator communication data information, organizes the information into instructions, and transparently transmits the information to the management terminal 120 through the communication channel 150;

[0083] The management terminal 120 pa...

Abstract

The invention discloses an eSIM (emulation subscriber identity module) card and a method for operating the same, and is applied to the field of communication. The eSIM card comprises a safety elementand a communication element. The method includes steps of establishing communication channels by the aid of the communication element; transmitting authentication information via the communication channels; transmitting operator communication data downloading requests after successful authentication is carried out; downloading operator communication data by the aid of the established communicationchannels; installing the operator communication data in the safety element. The eSIM card and the method have the advantage that operator management data can be downloaded in the eSIM card under theconditions that software and hardware environments of existing management terminals do not need to be transformed and machine card access mechanisms do not need to be preliminarily loaded in the eSIMcard.

Description

Technical field [0001] This application relates to the field of communications, and in particular to an eSIM card and its working method. Background technique [0002] With the popularity of mobile terminals, the use of SIM cards has become a bottleneck restricting their development. The hardware of the mobile terminal needs to reserve a card slot for the SIM card, and users need to go to the business hall to purchase the SIM card separately. The use of the SIM card brings a lot of inconvenience to the mobile terminal manufacturers and users. [0003] The eSIM card embeds the traditional SIM card directly on the device chip instead of adding it as an independent removable component. Users can download the communication data of multiple operators so as to freely choose to activate one of them at any time Business access. The eSIM card solves the problem of inconvenience in using the existing SIM card. [0004] There are two existing eSIM card download mechanisms, one is for the exi...
