Abstract

The invention discloses a method and device for updating a smart card operating system for updating JAVA cards through the software upgrading mode and keeping the data of installed applications unchanged so as to reduce a waste of JAVA cards and increase user experience. The method for updating a smart card operating system comprises following steps: obtaining a system JAVA package after a chip operating system COS is updated; according to the package identification of the obtained system JAVA package, updating a corresponding system JAVA package in the COS; updating target object data corresponding to the system JAVA package; and updating and calling call information of each application of the system JAVA package.

Description

technical field [0001] The invention relates to the technical field of smart card operating systems, in particular to a method and device for updating smart card operating systems. Background technique [0002] E-wallet is a financial IC card application designed to facilitate cardholders' small consumption. As mobile terminals increasingly become an indispensable communication tool for people, it will be an irresistible trend to implement electronic wallet services through mobile terminals. During specific implementation, a USIM (Universal Subscriber Identity Module, Universal Subscriber Identity Module) card (also called a JAVA card) inside the mobile terminal may be used to carry the electronic wallet service. [0003] At present, when users use the electronic wallet service carried by the mobile terminal, if there is a problem with the JAVA card and the user cannot use the electronic wallet service, the user needs to replace the JAVA card before continuing to use the el...
