Updating method of user signing data, management system, eUICC and terminal

Abstract

The invention discloses an updating method of user signing data, a management system, an eUICC and a terminal, and relates to the communication field. The method comprises steps that the eUICC sends a request for acquiring an address of a signing data management platform to a server; the eUICC establishes a channel with the signing data management platform by finding the address returned by the server; and the eUICC downloads user signing data from the signing data management platform and updates the user signing data. According to the invention, capability of an eUICC card is expanded; remote management of profile is quite safely achieved based on the eUICC card in a hardware mode; safety of updating and management of the profile is quite high; functions of remote downloading, activation, updating and the like of the profile are quite safely achieved; the requirement for flexibly configuring the profile in the Internet of Things is met; and operator switching is effectively performed.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for updating user subscription data, a management system, an eUICC and a terminal. Background technique [0002] Profile is a collection of files, data and applications, including user identification information and service contract information. The existing pluggable SIM (Subscriber Identity Module, customer identification module) card is an integration of software and hardware, changing the profile requires replacing the hardware card at the same time, which cannot meet the needs of on-demand signing and flexible profile configuration in international roaming services. In the existing technology, the remote management of Profile is usually realized through OTA (Over-the-Air Technology) or softsim, but the existing method cannot safely realize the remote management of Profile, and the traditional pluggable Sim The card OTA method cannot realize the...

The existing pluggable SIM (Subscriber Identity Module, customer identification module) card is an integration of software and hardware, changing the profile requires replacing the hardware card at the same time, which cannot meet the needs of on-demand signing and flexible profile configuration in international roaming services

In the existing technology, the remote management of Profile is usually realized through OTA (Over-the-Air Technology) or softsim, but the existing method cannot safely realize the remote management of Profile, and the traditional pluggable Sim The card OTA method cannot realize the remote update and management of the entire profile, and the Soft Sim solution lacks the hardware protection of the UICC. The pure software implementation solution is vulnerable to attacks and has low security. The implementation methods of various terminal manufacturers are incompatible with each other.
