Abstract
A file update message received in an integrated circuit card in a mobile communication apparatus having apparatus memory causes the card content to be updated in compliance with the file update message. An apparatus memory refresh command issued from the card causes the apparatus memory to align automatically with the updated card content.
Claims20
A method including:
- receiving an update message at an integrated circuit card comprising card content stored in a card memory of the integrated circuit, wherein the integrated circuit card is disposed in a mobile communication apparatus comprising an apparatus memory;
- updating the card content in the card memory of the integrated circuit card in compliance with the update message;
- issuing from the integrated circuit card an apparatus memory refresh command;
- and
- refreshing the apparatus memory to align the apparatus memory with the updated card content in the card memory.
An integrated circuit card comprising:
- a card memory storing a card content and an operating system for operating the integrated circuit card and an instruction code to be executed in the integrated circuit card by the operating system, wherein the integrated circuit card is configured to be inserted in a mobile communication apparatus having an apparatus memory, wherein the instruction code when executed by the operating system is configured to
- receive an update message;
- update the card content in the card memory of the integrated circuit card in compliance with the update message;
- issue from the integrated circuit card an apparatus memory refresh command configured to refresh the apparatus memory to align the apparatus memory with the updated card content in the card memory.
The apparatus of claim ii, wherein the command issue code is written in the reserved for future use or RFU bytes of the memory location for the life cycle status information.
The apparatus of claim ii, wherein the command issue code is written in the proprietary bytes of the memory location for the life cycle status information.
A mobile communication apparatus comprising:
- an apparatus memory;
- a receiver configured to receive an update message;
- an integrated circuit card comprising a card memory storing a card content, an operating system for operating the integrated circuit card, and an instruction code to be executed in the integrated circuit card by the operating system, wherein the instruction code when executed by the operating system is configured to
- receive the update message from the receiver;
- update the card content in the card memory of the integrated circuit card in compliance with the update message;
- issue from the integrated circuit card an apparatus memory refresh command configured to refresh the apparatus memory;
- and
- refresh the apparatus memory to align the apparatus memory with the updated card content in the card memory.
