Problems solved by technology

[0003] However, in the traditional mobile phone system, since only single-language application programs can be logged in, when USIMs with different language interpretation programs are mixed among users, the program cannot be downloaded to all users through the mobile phone system. , traditionally, there is no solution to this problem at all

Embodiment Construction

[0013] Next, embodiments of the present invention will be described.

[0014] 1 is a conceptual diagram illustrating the present invention, FIG. 2 is a process diagram illustrating a download program, FIG. 3 is a diagram showing a representative program language of an IC card, and FIG. 4 is a diagram showing a selection screen of a download program.

[0015] The USIM 1 has a storage device and a processing unit (CPU), and is a module having a function of installing an execution program translated in machine language or other languages. The module is separated from the IC card in the form of a card. Therefore, the configuration of the physical interface (contact end face) of the electrical connection portion, and the electrical communication method, etc., are completely the same as those of the IC card. Personal information is stored in the USIM, and once it is assembled into a mobile phone with a transceiver function, the function of the mobile phone can be realized. The USIM...

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.

Description

technical field [0001] The invention relates to a system for downloading programs from a program server to a universal subscriber identification module through a portable telephone system. Background technique [0002] In Europe, the function of a mobile phone is realized mainly by setting a plug-in-shaped Subscriber Identification Module (Subscriber Identity Module: abbreviated as SIM) in which the program for realizing the function of the mobile phone is embedded in an IC chip on the casing of the mobile phone. Now, a Universal Subscriber Identity Module (Universal SIM: hereinafter referred to as USIM) that can use this SIM specification worldwide is being considered. [0003] However, in the traditional mobile phone system, since only single-language application programs can be logged in, when USIMs with different language interpretation programs are mixed among users, the program cannot be downloaded to all users through the mobile phone system. , traditionally, no solu...
