Abstract:
A smart card for a mobile station, having a first data processor, utilized in a mobile communications system, the smart card comprising:an interface capable of transferring data items from and to the mobile station; a memory capable of storing the data items; and a second data processor interacting with the first data processor by receiving data items therefrom, and transmitting data items thereto, in a predetermined coding format, such that the smart card is compatible with different mobile stations implementing a common mobile station/smart card interfacing standard, and storing and retrieving the data items to and from the memory, wherein the second processor is adapted to convert a data item received via the interface from the predetermined coding format to a compressed coding format and to store the data item in the memory in the compressed coding format, and wherein the second processor is adapted to convert the data item, when retrieved from the memory, from the compressed coding format to the predetermined coding format before transmitting the data item via the interface in the predetermined coding format, wherein the compression and decompression is performed on the smart card to reduce the amount of memory occupied by the data item on the smart card, without diverging from the mobile station/smart card interfacing standard.
