Problems solved by technology

The latter needs to download the roaming site operator's configuration file (profile, including file system, network access key parameters, auxiliary security domain, application and other data) information. Before and after arriving at the roaming site, it is necessary to manually switch the eSIM Profile through the client system to achieve login. However, due to special circumstances (such as wild animal tracking and positioning equipment, etc.), manual switching is difficult or impossible for some IoT terminals, which brings great inconvenience to use.

Embodiment 1

[0029] After the device is connected to the network, the eSIM card can actively query the network access information of the area, and the information format is MCC (Mobile Country Code) + MNC (Mobile Network Code).

[0030] According to the definition of the specification, the encoding format of MCC+MNC is as follows:

[0031] MCC digit 2

MCC digit 1

1st byte

MNC digit 3

MCC digit 3

2nd byte

MNC digit 2

MNC digit 1

3rd byte

[0032] figure 1 It is a flow chart of the method for automatically switching the configuration file of the eSIM card provided by the embodiment of the present application. Such as figure 1 As shown, the method for automatically switching the configuration file of the eSIM card includes the following steps:

[0033] S101: The eSIM card regularly detects the area where the terminal is currently located and the current network access status.

[0034] If the network access status indicates that the netwo...

Abstract

The invention provides an eSIM card and a method and system for automatically switching a configuration file of the eSIM card. The method comprises the steps: enabling an eSIM card to regularly detecta region where a terminal is currently located, so as to judge whether the terminal is in a roaming state or not; enabling an eSIM card to obtain the network entry information of the terminal in thecurrent region if the terminal is in the roaming state, and transmitting a preferred list obtaining request to a third side management platform; receiving the preferred list, sent by the third side management platform, of the current region, and storing the preferred list; judging whether the eSIM card is provided with a configuration file of a first preferred operator in the preferred list or not; switching the configuration file of an original operator in the eSIM card to the configuration file of the first preferred operator if the eSIM card is provided with the configuration file of the first preferred operator in the preferred list, and notifying the terminal provided with the eSIM card of carrying out the restart and reentry. According to the invention, a user does not need to carryout manual operation, and the user experience is good.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to an eSIM card, a method and a system for automatically switching configuration files of the eSIM card. Background technique [0002] With the gradual popularization of Internet of Things technology, various forms of Internet of Things products have gradually come out to meet the needs of the development of the times, and more and more traditional devices (such as cars, monitoring equipment, etc.) are embedded in communication modules to become Internet of Things terminals. eSIM (Embedded Universal Integrated Circuit Card) is the core of the development of the Internet of Things. Through eSIM technology, the Internet of Things terminal can log in to the operator's network. In view of the different coverage of operator networks in different countries and regions, IoT terminals may be roaming at any time. It is very important whether the terminal can log in to ...
