摘要

PROBLEM TO BE SOLVED: To constitute a communication management system which performs the acquisition and dealings of information contents and functions.

SOLUTION: A terminal device 2 transmits its own equipment information and an information content acquisition request to a contents distribution device 3. Based on the information content in the acquisition request and the equipment information, the contents distribution device 3 designates a distribution request for a program, which concretizes the information content in the terminal device 2, and transmits the program to a program distribution device 4 and further transmits a function specification usage permission request required for implementation of the functions to a license management device 5. When receiving the usage permission request, the license management device 5 transmits the usage approval for the function specification to the program distribution device 4 and the contents distribution device 3. The program distribution device 4 transmits the program to the terminal device 2 only when it receives the usage approval. The contents distribution device 3 transmits the information contents to the terminal device 2 only when it receives the usage approval.
