Abstract

The present application discloses an eSIM card and a management method thereof, wherein, the eSIM card comprises an ISD, an ISD-R and ECASD, the ISD-R managing at least one ISD-P, each ISD-P managingADF; ADF of ISD-P in active state is migrated to the ISD so that the ADF of the ISD-P in the currently active state is managed by the ISD. The application achieves the technical effects of reducing the memory consumption of the eSIM card, improving the management efficiency and reducing the production cost and the later maintenance cost.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to an eSIM card and a management method. Background technique [0002] eSIM is the abbreviation of Embedded SIM (Subscriber Identity Module, also known as subscriber identity card or smart card) embedded SIM card, which is a new product form of SIM card. SIM cards are usually used in mobile phones, while eSIM cards can be used in the field of the Internet of Things. They can be fixedly welded on the device terminal without moving or replacing, and can flexibly switch the information of the user's contracted operator (such as China Mobile, China Unicom or China Telecom, etc. . [0003] The information of the user's contracted operator is mainly completed by installing ISD-P (Issuer Security Domain Profile) and downloading its profile (user configuration file). Such as figure 1 As shown, Profile includes security domain (MNO-SD, SSD), file system (FileSys...
