Embodiment Construction
[0038] Data synchronization refers to keeping the data stored in the OS-SIM card consistent with the data stored in the synchronization server. The common data synchronization needs to be realized through the mobile platform. The OS-SIM card must be installed in the mobile platform (such as a mobile phone), and communicate with the mobile platform (such as a mobile phone) through a standard 7816 or USB interface, and the synchronization server It is also necessary to establish a data path with the mobile platform and adopt a corresponding synchronization protocol to complete the data synchronization with the OS-SIM card. Since the data synchronization between the OS-SIM card and the synchronization server must be completed through the mobile platform, the synchronization speed is restricted by the mobile platform, and the security of the synchronization data is not guaranteed.
[0039] refer to figure 1 , in order to reduce the intermediate link of the mobile platform and com...
