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] Hereinafter, embodiments of the present invention will be described.

[0014] figure 1 Is a conceptual diagram illustrating the present invention, figure 2 Is a diagram illustrating the process of downloading the program, image 3 It is a drawing showing the representative programming language of IC card, Figure 4 This is a diagram showing the selection screen of the download program.

[0015] The USIM1 has a storage device and an arithmetic processing device (CPU). It is a module with the function of installing an execution program translated in machine language or other languages. The module separates the IC card in the shape of a plug-in. Therefore, the physical interface structure (contact end surface) of the electrical connection part, and the electrical communication method, etc., are completely the same as the IC card. Personal information is stored in the USIM, and once it is assembled into a portable phone with a transceiver function, the function of the portab...

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 present invention relates to a system for downloading a program from a program server to a universal user identification module through a portable telephone system. Background technique [0002] In Europe, the function of the mobile phone is mainly realized by setting a subscriber identification module (SubscriberIdentify Module: abbreviated as SIM) in the shape of a plug-in IC chip that embeds the program that realizes the mobile phone function on the casing of the mobile phone. In recent years, Now, it is being considered that the universal subscriber identification module (Universal SIM: hereinafter referred to as USIM) of the technical specifications of this SIM can be used all over the world. [0003] However, in the traditional portable phone system, since only a single language application program can be logged in, when each user has a USIM with different language interpreters, the program cannot be downloaded to all users through the portable ph...
