Abstract: A service processing server for providing a communication processing service with an information providing server, to a cell phone belonging to a network capable of identifying subordinate cell phones, and including an application receiving part for receiving first communication terminal-specific information to specify a specific cell phone, and service-specific information in association with each other; a specific information generating part for generating second communication terminal-specific information; an approval requesting part for transmitting approval request information containing the service-specific information and the second communication terminal-specific information, to the information providing server; a result receiving part for receiving approval result information returned; and a registering part for performing a registration process for providing the communication processing service to the specific cell phone in accordance with reception of the approval result information.

Abstract: A message transmission system includes a registration accepting part for accepting a membership number, a subscriber telephone number, and a subscribed service ID; a subscriber information storage for storing membership numbers, subscriber telephone numbers, and subscribed service IDs in association with each other; a transmission request receiver for receiving a membership number of a message destination and a service ID of a Web server from the Web server or from communication terminal; a communication address converter for referring to the subscriber information storage on the basis of the received membership number and service ID to retrieve the subscriber telephone number corresponding to the membership number and service ID; and a message output part for outputting a predetermined message while designating the retrieved subscriber telephone number.

Abstract: Mobile unit 16 which can activate Java-AP software obtains ADF 205 from IP server unit 13, receives SDF (security descriptive file) 204 by using ADF 205 from administering server unit 18 which a trustworthy organization (a communication provider which administers mobile packet communication network 15) administers, and obtains Jar file 206 by using ADF 205 from IP server unit 13. Then, mobile unit 16 installs Java-AP software containing these files. Java-AP, which is achieved by activating the installed Java-AP software, operates within the range of authorization expressed by policy information contained in SDF 204.

Abstract: In a mobile phone 600, a trusted application and a download helper are executed to generate an area reservation request message for requesting reservation of a storage area for storing a program, data, and the like. This message is transmitted to an area management server 500. When the area management server 500 receives the area reservation message, it transmits an area reservation instruction message to the mobile phone 600. When the mobile phone 600 receives the area reservation instruction message, the storage area for storing the program, the data, and the like is reserved in an external memory. A downloaded program and data are stored into this area.
