The invention relates to a method for switching a subscription of a user from a first MNO () to a second MNO (), characterized in that it comprises requesting to a remoter server switching from the first MNO to the second MNO and temporary storing data updates related to the second MNO in a dedicated file.

Method for switching a subscription from a first MNO to a second MNO

This invention relates to an integrated circuit device comprising a memory and at least one application program residing within said memory. This invention is characterized in that the application program comprises at least one configurable variable and a list of at least one reference element, and in that said memory includes, on the one hand, at least one means for initializing said variables, wherein said means is configured with several parameters, one of which parameters is said reference element list, and on the other hand, a command for sending data that contain, in particular, values to be assigned to the configurable variables. This invention can be applied, in particular, to smart cards.

Device and method for initializing an applicative programme of an integrated circuit card

A data processing system which includes memory, a processor connected to the memory, and logic for causing the processor to perform a method for executing computer code having a plurality of transactions within the computer code. The method includes steps for examining the computer code being executed for a change in observable state; for storing data for the executed computer code that are part of the plurality of transactions within the computer code; for maintaining a pointer to the logical beginning of the stored data and maintaining a pointer to the end of the stored data for the last transaction within the computer code to be fully executed; and responsive to detecting a change in observable state, for committing a portion of the stored data.

Method and apparatus for processing transactions in a data processing system

A smart card which includes a non-volatile read/write memory, a processor connected to the memory, and an installer module configured to cause the processor to receive computer code having method bodies into the memory, and further configured to cause the processor to perform a method for determining the instruction boundaries of the method bodies and resolving unresolved references within the method bodies. The method includes steps for examining each instruction for a forward jump instruction and a valid ending instruction, maintaining a farthest logical return pointer corresponding to the instruction for which the farthest forward jump instruction or the farthest valid ending instruction is detected, resolving unresolved references within a method body starting with the first instruction and ending with the instruction corresponding to the farthest logical return pointer, and terminating the examination of each instruction within a method body when the instruction under examination is beyond the instruction corresponding to the farthest logical return pointer.

Method and apparatus for linking converted applet files without relocation annotations

A smart card which includes a non-volatile read/write memory, a resolve buffer, a processor connected to the memory and the resolve buffer, and an installer module configured to cause the processor to receive computer code having unresolved references into the memory, and further configured to cause the processor to perform a method for resolving unresolved references. The method including steps for copying the contents of the memory into the resolve buffer, detecting unresolved references in the computer code, determining the resolved reference for each of the detected unresolved references, updating the contents of the resolve buffer with the resolved references, and replacing the contents of the memory with the contents of the resolve buffer.
