Communication method, communication system, communication device, managing device, recording medium and user information module

摘要

The object is to provide a communication system enabling a server to obtain a grasp of the behavior of users on a communications network even when communication is performed between users on the communications network without going through the server. A communication apparatus 31 has a user information module containing user attribute information indicating an attribute of a user 41. When the communication apparatus 31 communicates with a communication apparatus 33, the communication apparatus 31 sends user attribute information of the user 41 to the communication apparatus 32 and receives and holds user attribute information of a user 42 from a communication apparatus 32, and the communication apparatus 31 sends said held user attribute information of the user 42 to a management apparatus 5.
