DISTRIBUTION METHOD, DISTRIBUTION SYSTEM, AND TERMINAL DEVICE

摘要

A mobile device (16) capable of starting Java-AP software acquires an ADF (205) from an IP server device (13). By using the ADF (205), the mobile device (16) receives an SDF (security description file) (204) from a management server device (18) managed by a reliable organization (communication company managing a mobile packet communication network (15)). Next, by using the ADF (205), the mobile device (16) acquires a Jar file (206) from an IP server device (13). The mobile device (16) installs in itself Java-AP software containing these files. The Java-AP realized by starting the Java-AP software operates within a range of authority represented by the policy information included in the SDF (204).
