Data updating method, data updating device and data updating system of eUICC module

Abstract

The invention belongs to the technical field of Internet of Things, and particularly relates to a data updating method, a data updating device and a data updating system of an eUICC module. The data updating method is used for carrying out data updating on the eUICC module; the method comprises the steps of calculating a data updating increment packet of the eUICC module relative to a data supportplatform according to a hardware support version of the eUICC module, a current data version of the eUICC module and the data support version of the data support platform; obtaining the current resource utilization rate of the eUICC module in real time, and calculating the number of transmission update blocks according to the current resource utilization rate of the eUICC module and the data update increment packet; and carrying out data updating on the eUICC module according to the number of the transmission updating blocks. According to the method, the necessary version and the data updating increment packet which are matched with the eUICC module can be automatically matched, block downloading and updating are achieved according to the current resource utilization rate of the eUICC module, and therefore small system time delay is achieved, and waste of flow charges is avoided.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a data updating method, a data updating device and a data updating system of an eUICC module. Background technique [0002] With the development and wide application of mobile communication technology, the Internet of Things business is also developing rapidly in the direction of mobility, easy connection and remote management. Therefore, the key module smart card that promotes Internet of Things terminals to access mobile networks has generated new technical requirements: A new smart card form eUICC (Embedded UICC, embedded universal integrated circuit card) and a remote management system established to support the eUICC form. [0003] The eUICC module includes a non-pluggable smart card (eSIM) solidified in the terminal device, that is, the SIM card is directly embedded on the device chip and cannot be replaced at will, instead of being added to the d...

Problems solved by technology

[0004] With technology upgrades, version updates are inevitable between the eUICC module and the remote management system. Although the eUICC module comes with a lightweight operating system, its processing and analysis capabilities are limited, and the eUICC module is compatible with the system version when updating data. Limited, and the update package provided by the remote management system usually includes all the data of each version in order to be compatible with all eUICC modules. If the default update version is used, not only the system delay will be large, but it may also exceed the hardware support of the current eUICC module. cause system error
