Abstract

The invention provides a program-downloading system comprising a USIM (1) from and in which data can be read and written via a cellular phone terminal (2) and which holds a given program specification and encryption communication means, and a program server for communicating with the USIM via the cellular phone terminal and providing a program to the universal subscriber identify module according to the given program specification. The program server prepares a program list that can be provided according to a program specification sent out of the USIM via the cellular phone terminal and transmits the program list to the cellular phone terminal, so that when program information selected by the USIM from the program list is received via the cellular phone terminal, a given encryption communication means is selected out of an encryption communication means list transmitted out of the USIM to encrypt a program, which is then downloaded to the USIM.

Claims

1. A program-downloading system for a universal subscriber identify module, characterized by comprising a universal subscriber identify module from and in which data are read and written via a cellular phone terminal and which holds a given program specification and encryption communication means, and a program server for communicating with said universal subscriber identify module via said cellular phone terminal and providing a program to said universal subscriber identify module according to said given program specification, wherein:

said program server prepares a program list that can be provided according to a program specification sent out of the universal subscriber identify module via the cellular phone terminal and transmits said program list to the cellular phone terminal, so that when program information selected by the universal subscriber identify module from said program list is received via the cellular phone terminal, a given encryption communication means is selected out of an encryption communication means list transmitted out of the universal subscriber identify module to encrypt a program, which is then downloaded to the universal subscriber identify module by virtue of encryption communication via the cellular phone terminal.

2. The program-downloading system according to claim 1, characterized in that the program list transmitted to said universal subscriber identify module is indicated on a display of the cellular phone terminal for selection.

3. The program-downloading system according to claim 1, characterized in that the encrypted program received at the cellular phone system is written in the universal subscriber identify module by means of encryption communication.
