Abstract

A communication terminal capable of utilizing a plurality of radio communication services respectively provided by a plurality of radio communication systems establishing a shared radio communication system is provided. The communication terminal comprises a hardware processing unit for performing common hardware processing necessary for utilizing each of the radio communication services; an IC card that stores a plurality of communication software packages necessary for respective radio communication services; a software selection unit that selects one communication software package out of the communication software packages stored in the IC card, which corresponds to a communication service to be utilized; and a software executing unit that executes the selected communication software package.

Description

technical field [0001] The present invention relates to a communication terminal capable of utilizing communication services provided by a multi-wireless communication system, a general-purpose wireless communication system constituted by the multi-wireless communication systems, and an IC card writing device for writing software into an IC card. Background technique [0002] In recent years, wireless communication systems of various communication methods have been developed. These wireless communication systems are different in areas where services can be provided, service contents, and the like. Therefore, the user must use a communication terminal such as a mobile phone according to the wireless communication system. However, since it is inconvenient to use multiple communication terminals, a new type of communication terminal (hereinafter referred to as "universal communication terminal") has recently been developed that can utilize the communication services provided b...
