The invention discloses a convergence service terminal, which comprises a terminal capacity information module and a terminal capacity proxy module, wherein the terminal capacity information module is used for describing terminal capacity of the convergence service terminal and generating description information of the terminal capacity; and the terminal capacity proxy module is used for scheduling the terminal capacity according to a request of calling the terminal capacity by a convergence service server and reporting the terminal capacity to the convergence service server so that the convergence service server establishes a convergence service in combination with the terminal capacity. In addition, the invention also discloses the convergence service server, a convergence service system, a convergence service establishing method and a convergence service using method. The user terminal capacity is introduced in the convergence service to be taken as a service and information sourceof convergence application, so that a user can establish and use the convergence service more conveniently and flexibly and service experiences of the user can be enhanced.
